I have a machine with an AMD Athlon 1 GHz processor on a Jetway 663AS Pro rev 1.2 Motherboard, flashed with the latest BIOS available from Jetway.

I believe the processor is a socket A type A1000AMT3B It is announced in the post during bootup as AMD Athlon TM 1000MHz (100x10.0).

I would like to put the fastest processor this motherboard will accept in place of the 1 GHz one and believe this to be an AMD Athlon A1400AMT3B, which is poving difficult to get hold of. Are there any other processors that are available to provide me with such and upgrade? The 256 KB on-board cache is the obvious attraction of the Athlon processor.

I have seen a number of the 133 MHz (266 MHz FSB) processors but a lot less 100 MHz (200 MHZ FSB) ones about. Can a 266 MHz one be "unlocked" to run at 200 MHz (underclocked) and still give me 1.4 GHz at 10x?

Any help or advice would be appriecated.

Not at 10x, Your 1000 runs at 10x, not the motherboard, What you'd want is a 2400+ which runs at 15x, which will give you 1500mhz, but its not really a good solution, since they don't perform well with 168 pin SDram, they are built for ddr ram. Your best bet would be to upgrade your mobo and ram first. Socket A's can be had fairly cheap, depending on tha make and features, But Ram is expensive comparabley. Then you still need to buy a cpu. Here is about the biggest one you can run efficiently, but for the price, you can buy a new sempron 2200 for just a few bucks more http://www.compgeeks.com/detai...nvti...00AMS3B&cat=CPU' ">http://www.compgeeks.com/detai...tid=A1300AMS3B&cat=CPU

Thanks for the reply.

You are right about leaving the old motherboard behind, I did that about six or seven months ago with a build on a Gigabyte GA-8S648 using a 2.4 GHz P4 and 1 GB of RAM. The Jetway AMD Athlon machine is number 2 on my network and is taking over from number 3, a PCChips m571 with an AMD K6 2 450 Mhz processor, as my preferred tinkering machine.

So I know there are better routes than upgrading from the 1 GHz processor I just fancy doing it. I also fancy a K6 3 in the m571 and I am on the look out for one of those too! So thanks for the link I may just go for that if they will ship to England UK

Jetway do not say anything about using the 2400+ that you have mentioned but I think it is a long time since they showed any interest in such old MB's as the 663AS Pro for them to have posted anything new about this board!

Hi Les,

Jetway does have something to say about the Athlon XP 2400+, and it's "No."

Here is a direct link to the CPU support table for your motherboard:
http://www.jetway.com.tw/evisn.../CPU...ort/663AS12.htm' ">http://www.jetway.com.tw/evisn...PU_support/663AS12.htm

The table shows many "Athlon 0.18u" (Athlon XP Palomino) and "Athlon 0.13u" (Athlon XP Thoroughbred) CPUS, and shows "NO" next to all of them. I am pretty sure it is not just because they are 133 FSB processors. Here's why; the Durons of 1.0 through 1.3 GHz (i.e. Duron Morgan), which run with 100FSB but are castrated Athlon XP Palominos, also say "NO." So it's not just the FSB; it's the XP-type processors in general.

The mobo has the VIA KT133 chipset, and many (all? -- I'm not sure) with this chipset have trouble running Athlon XPs even if they have "overclocking" settings for 133 FSB, as some do.

Bottom line, I don't think you stand a good chance of underclocking an Athlon XP on your motherboard.

As to what you can do (and since this is your tinkering machine): The 100 FSB Athlon Thunderbirds are expensive because they are the top of the line for board like yours. The 133 FSB versions are much more reasonable, as you've seen. A lot of people overclocked T-Birds, and there is still information on the Internet about this, including unlocking and resetting their multipliers, if necessary. So you can probably run a 133 FSB version underclocked, (you would probably not have to do anything other than drop it in), but you probably could also run it as a 200MHz version and increase the multiplier to bring it up to full speed. Or beyond...

You could also overclock the 1000 you already have.

Hi John,

Thanks for the reply, much appreciated.

I think Jetway might be down this morning as the link you gave me is failing as is my own way in. You are right though I remember now that I only did a cut and paste of the processors that were OK with the 663AS pro so my local reference is what is lacking any that are not! Put it down to my advancing years. It was from this table that I came up with the A1400AMT3B as the best processor I could go for with this board.

I did download a load of info about overclocking by shorting links using a "graphite" pencil or with a conducting paint or epoxy but you say that maybe I could drop an S3C straight in. As the motherboard clock speed is 100 MHz the S3C would presumably double that to 200 MHz but what would the multiplier be?

This confuses me because when I tinkered with my old m571, to replace the Cyrix P233 with the AMD K6 2 450, it was a simple process of moving jumpers about as the K6 reads the 2x multiplier as 6x. The Jetway board seems to read the processor and do this sort of thing in the post or the BIOS. Is this right?

The links I have mentioned shorting claim to "unlock" the processor. So if it is unlocked what speed would this "autodetect" feature that my board appears to use, actually set. I bet you can tell that I am out of my depth now.

I am watching a 200 MHz 1.4 GHz processor on eBay but would still like to know if I could utliise a 266 MHz one!

Any advice re foregoing threads?

Hi Les,

Sorry for no further response. I am not going to give you specific advice on raising the multiplier and dropping the FSB on a 266 T-Bird, to make it run like a same-speed 200 T-Bird. This is because it may involve modifying the processor, and since I have never modified a T-Bird, I am not the one to walk you through that. But I am sure if you Google with search terms like thunderbird, overclock (even though you are not trying to overclock the methods are similar), and multiplier, you will find articles on this.

One guide, which assumes a fair amount of knowledge, is:
http://ocinside.de/index_e.html' ">http://ocinside.de/index_e.html
Click the Workshop icon at the left, then select "Interactive painting guide - TB and Duron overclocking by pencil and knife" from the list of "AMD Socket A guides." Don't try this at home without more detailed help or mentoring.

I can also try to get the attention of someone with experience on this. It may take a day or two considering the holiday weekend.

A very good thing to know is if your motherboard has a multiplier adjustment feature, either by jumper or in the BIOS. This could minimize the needed modification, or eliminate it if the CPU is already unlocked.

Here's how I look at the risk of modifying the CPU. Prices per Pricewatch, with shipping:

Athlon XP 1400 200: $148
Athlon XP 1400 266: $ 65
Difference: $83

In the unlikely event you screw up a 266 version modding it by carefully applying proven methods, you lose $65. If you buy a 200 version, you automatically lose $83.

Hi John,

The reply is much apprieciated.
The Jetway Link you gave me came good and I have to admit to having been there myself in the past so I should have remembered this.

I have used Google to trawl for information about overclocking with pencil lines, conductive epoxy etc. and reckon I could do it if the mood takes me.

My Jetway Motherboard and its BIOS are my biggest unknown. I have got an AMD K6 2 to work at 450 MHz where the x2 multiplier setting on the MoBo is read by the processor as x6 but this was done with physical jumpers that I could understand and a lot of help on the EYO technical forum. It appears to me that this Jetway board recognises a flag maybe read from the processor and sets the multiplier to suit in the post.

If I un-lock a 266 MHz processor does this un-set this flag I have postulated and need something else to set the FSB? You can see this is where I am out of my depth and my searches so far have not come up with an answer but I shall keep looking.

Your sums on the economics of it are well appreciated as it is exactly what I have been toying with myself along with a K6 3 I have spotted that would make a good replacement for the K6 2 in my third machine!
What I cannot think of is a plausible explanation for the expenditure to run by the wife for either machine!



The edit:
P.S. I don't speak German so I have posted in the English Forum at: http://ocinside.de/index_e.html' ">http://ocinside.de/index_e.html Thanks for the link.

I have been having a play with the Painting Guide you referred me to at ocinside.de and cannot see how an A1400AMS3B ever works as with the FSB at 100 MHz making the Systembus 200 MHz the maximum multiplier is 6.25 hence the processor runs at 1250 MHz maximum not 1.4 GHz! What am I missing

I think there was some kind of scheme whereby some of the lower multipliers were remapped to make the new higher multipliers (like the 14X).

But I found something interesting. Although the KT133 chipset in your motherboard officially supports only 200FSB CPUs (100 MHz CPU clock setting), there are settings in the BIOS up to 133. This is on page 40 of the manual. If you need the manual it's here:
http://www.jetway.com.tw/evisn...d/ma...al/663PROR1.ZIP' ">http://www.jetway.com.tw/evisn...ad/manual/663PROR1.ZIP

So this may allow you to run The 266FSB T-Bird 1400 at stock settings. Also take note that when the CPU clock is at 133 MHz, the PCI clock is at the normal 33 MHz, so your other system components would not be overclocked.

snooper,

John has asked me to see if I can help you out a bit with your Jetway 663AS Pro rev 1.2 Motherboard, and the problem of getting a faster CPU to work in it.
I think I can help.

First, there seems to be a little confusion about this dammed 100/200 vs 133/266 MHz/DDR FSB thing.
The AMD CPUs that we are discussing run at either 100 or 133 MHz.
But the Athlons can transmit information or 'data' on BOTH the rising and falling edge of a pulse... DDR or "Double Data Rate"
It really only runs at 100 or 133 MHz, but because of the "Double Data Rate" it is often refer to as a 200 or 266 MHz processor... it sounds better if you are trying to sell one.

So, in the case of the 1400 MHz Athlons we're discussing, one will run at 14x 100 = 1400 MHz
That's the A1400AMS3B
The other runs at 10.5x 133.3 = 1400 MHz
That's the A1400AMS3C

So if you run the A1400AMS3C in your Jetway 663AS, which can only run at 100 MHz, or slightly more, because of the KT133 chipset's limitations, you will end up running it at 10.5x 100 = 1050 MHz
Which is a very small improvement from where you are now... only 50 MHz better.

But, it is possible to change that 10.5x multiplier to 14.0x (by cutting / joining the L3, L4 and L11 bridges), and run it in yours at 14.0x 100 = 1400 MHz
If you are game for learning a bit about 'hard-modding' an Athlon T-bird, I'll be happy to 'walk-you-through' it.

@ John,
You posted while I was composing... the BIOS (CMOS) may allow settings up to 133 MHz, but I don't think the KT133 chipset is capable of much more than 115 ~ 118 MHz

@Milt-- Bummer on the limited FSB of the KT133. It was starting to look easy. I was still living in a Socket 7 world when KT133 came out.

@ Les-- You are in the best of hands now.

Hello Milt (& John),

I saw the mention of this 133/33 MHz MoBo clock settings on page 40 of my manaul when I was having a scan throught it after my last post and was puzzled because the orginal link you gave me to Jetway definitely say that 266 (133x2 as Milt explains) won't work and now I can see why if 118 MHz max is the best you can get.

I am game to unlock an A1400AMS3C's multiplier and can see the basics of what is involved. As a constructor of HiFi, when tracks on printed circuit boards were 1 mm wide and apart and managing to chip a playstation for my son some years ago when I realised how much smaller everything had become, I cannot help wondering why a little bit of tinning with some solder to bridge the links on the processor is not a possibility. I guess this is a no no or it would have been advocated before now.

Milt I would be most grateful for a walk through the process but at the moment this would be in advance of me doing it as I have yet to obtain a faster processor. I have this in hand with an eBay auction closing here in the UK shortly so I may be lucky.

All this information and advice is very much appreciated.

snooper,

Good luck on the eBay auction!

Unlocking the early Athlon 'Classic' Thunderbirds basically involves cutting or 'blowing' all of the L3, L4, and L6 bridges, so that YOU get to chose the multiplier that it will run at.
Once those bridges have been severed, you can easily re-join the appropriate ones with a common 2B pencil... the graphite in 'pencil lead' is electrically conductive enough to form a 'new bridge'
If you chose the 'wrong' multiplier, or just want to try a higher or lower multiplier, it's $hit-simple to just erase your pencil lines and start over.
If you have the skills, and the tools, to create a permanent 'solder bridge', once you have settled on the 'best' multiplier, so much the better.
You can also do the same with a conductive pen, or a 'Windshield Defogger Repair Kit' from your local Auto Supplies store.

Cutting, or 'blowing' the bridges is the hardest part.
Personally, I've used a mini-Dremel with a diamond bit on it for all of my early experiments.
But, I really believe that the easy, 'clean' way to cut them is to 'blow' them, like tiny little fuses, using your choice of 2 'C' cell batteries in series, a single 6v 'Lantern' battery, a single 12v 'D' cell battery, a 6v motorcycle battery charger, or the 5v line on any PSU.
Solder two needles to the ends of two wires, and use the needles to make contact with the individual bridge you want to blow.
In the case of a 1400'C' you would have to 'blow' two L3 bridges, and two L4 bridges.
The L6's are already 'open' on a 1400C

It will take a bit of searching, (or experimenting, on your part), to figure out how to get more than a 12.5x multi, but I'm sure we have enough smarts between the three of us, to get it done.
After all, AMD did it. So can we.

A good place to start your research is on this link...

Or, better yet, this one...

Hello again,

I took my eye off the ball and narrowly missed the one on eBay today but there are two more later in the week so I am still up for this.

Such a fast reply but I have read it through with http://ocinside.de/index_e.html' ">http://ocinside.de/index_e.html open alongside at the, "Interactive painting guide - TB and Duron overclocking by pencil and knife" section so that I could see the links that you refer to.

I selected:
1.75 Volts
5.25xSystembus(10.5xFSB)
LOCK - Change multiplier over the bridges

100 MHz FSB for 1050 MHz, which is what you explained an A1400AMS3C would run at in my machine without any modification.

I can see what has to be done and can see my way to getting it going at 1250 MHz but the 1400 still has me foxed despite a visit to Toms Hardware pages. The ocinside link you posted oddly enough takes me to the same place as the one above and dig as I may I cannot find anything about "resistors" but it is early days and I remember my early lack of understanding when folks told me an AMD K6 2 would read a 2x multiplier as 6x and run at 450 MHz with a 75 MHz FSB. Now I advocate it to others! Is there something similar with the Athlons or am I going to have to overvolt it a bit?

I have booted up the Jetway MB machine with my AMD 1 GHz processor and in the POST I see at the top of the screen:

Award Modular BIOS v6.00PGN
V.663AS/663ASPRO A15 12-14-2001 (This is the BIOS revesion I flashed it to)
Main Processor : AMD Athlon ™ 1000MHz(100x10.0)
Memory Testing : 786432K OK


and at the bottom right:

Vcore : 1.78 5V : 4.75
Vdd : 3.14 12V : 12.36
Vcc 3V: 3.14

I hit Del and took a look in the BIOS at:

Frequency/Voltage Control

and saw:

AutoDetect DIMM/OCI Clk : Enabled
CPU Host/PCI/Spread Spec : Default
CPU Vcore Select : Default

Exactly as shown on page 40 of my Jetway manual.

I paged up and down and could see the options available with these setting.
I still have not fully grasped the significance of how these settings have to be, to interact properly with the processor when its links are changed but I will get there eventually.

Thanks for the help to date.

Regards,

les.

P.S. An edit because I think the penny has just dropped.

You told me in an earlier post that selecting the 133/33 clk would give 115-118/33 MHz so if I choose this setting in the BIOS at CPU Host/PCI/Spread Spec and get 115 MHz and set the bridges for 12.5x that would give me 115x12.5=1437.5 MHz.
If I get 118 then the 12x bridge would do for 1416 MHz and maybe, if I am now cooking on gas, 118x12.5 for 1.475 GHz with perhaps a bit more voltage for stability. Am I on target or is it back to the drawing board with my thinking cap on?

Hi Les,

I think you are on the right track in comparing this situation to the old K62; that's what I meant by the lower multiplier settings being somehow remapped to be 13X and up. I did see something about 5X equaling 14X but I did not quote it earlier since it was talking about a specific ASUS mobo, and I was not yet sure it is universal. But probably it is, since the remapping would have to be built into the CPU, not the mobo, or the 1400 would not have worked on earlier motherboards. I just hope this remapping is in both 1400s and not just the 200 version.

When Milt said all you were likely to get was 115-118, he meant that the board may not boot or could be unstable if set at 133, not that it would produce a slower result. You would have to actually use a lower setting, such at the 112/37 shown in the manual. That's getting a bit lofty with the PCI clock (37), however.

Are you considering running some experiments with your Athlon 1000? You would probably have to increase the core voltage for some of those higher speed targets, if you got there at all. Although the idea is to see how far you can go with stock voltage first. With the 1400, however, we were just talking about raising the multiplier and lowering the FSB, and it doesn't care how it gets to 1400, so you would not need to increase voltage in that situation. Probably not for a mild increase beyond 1400 either. My 1200 does 1320 on stock voltage (just by increasing the FSB), although the 1400, already being the fastest in its class, may have less relative overclocking potential.

Hi Les,

You are right on target!
Whatever hat that is you're wearing... keep it! It's a good one.

I was hoping that you might have more options on that "Frequency/Voltage Control" page than just these three...

AutoDetect DIMM/OCI Clk : Enabled
CPU Host/PCI/Spread Spec : Default
CPU Vcore Select : Default

But, just having that last one, the "CPU Vcore Select", will be a help, if it will allow us to increase the Vcore voltage from the 'stock' 1.75v (although your BIOS 'reads' Vcore as 1.78v ), to about 1.85v (which is the max we can hope for, without physically modifying the motherboard)

I was hoping that we would have a 'CPU Frequency', or something along that line, that would allow us to raise the FSB up from 100 MHz in small steps, like 1 to 3 MHz at a time.

CORRECTION: I just DL'ed your manual, and in the section of your CMOS called "Frequency/Voltage Control", under...
"Jetway 663AS Pro rev 1.2"

This item allows you to set the CPU Host/PCI clock and Spread Spectrum.
The choice are:
Default,
100/33Mhz/-0.5%,
100/33Mhz/±0.25%,
100/33Mhz/±0.5%
102/34Mhz/Off,
104/35Mhz/Off,
106/35Mhz/Off,
107/36Mhz/Off
108/36Mhz/Off,
109/36Mhz/Off,
110/37Mhz/Off,
111/37Mhz/Off
112/37Mhz/Off,
133/33Mhz/-0.5%,
133/33Mhz/±0.25%,
133/33Mhz/±0.5%"
So we at least have options in the CMOS to 'push' it to as high as 112 MHz... but not the 115 to 118 that I was hoping for.

But, we may be able to use CPUCooL to accomplish the same thing, but do it from within Windows.
In order to use CPUCooL, we'll need you to get the number off your PLL (Phase Lock Loop) which is the 'clock generator' on your mobo.
It controls what combinations of CPU and PCI speeds are available for you to select.
CPUCooL usually has more options available than what you find in your CMOS.
Take a good look at your mobo, with a good strong light.
You'll probably need a small magnifying glass as well.
You are looking for a black, rectangular chip, with many tiny connector 'legs' along each side.
It will always have, right beside it, a shiny, oval, aluminum 'cannister' with "14.3 MHz" stamped on it's top.
We need the numbers off of the PLL chip next to that 'can'... that's where the small magnifying glass will come in handy.

Meantime, try 'bumping up' your current At hon 1000's FSB, a little at a time, and see how far you can get on the 'stock' 1.75v ( although your BIOS 'reads' Vcore as 1.78v )
You can probably get to 108, or 110, on the stock voltage.
That'll give you 1080, or 1100 MHz, on your next boot.
Then try raising your Vcore, (try +0.05v), using the "CPU Vcore Select" section of your CMOS.
With the 'extra' +0.05v you should be able to boot at 112 X 10.0x = 1120 MHz

This will be your first, and by far the easiest, attempt at overclocking... Good Luck!

OK, one step forward and two backwards.

I went into the BIOS and set:

AutoDetect DIMM/OCI Clk : Enabled
CPU Host/PCI/Spread Spec : 108/36/Off
CPU Vcore Select : Default

Saved and Exited but the boot process hung going into XP Pro at the XP screen with the blue dots that cycle across stuck so I pressed the reset button and went back into the BIOS and set:

AutoDetect DIMM/OCI Clk : Enabled
CPU Host/PCI/Spread Spec : 107/36/Off
CPU Vcore Select : Default

and this time it booted up OK after pausing to ask if I wanted Safe Mode or Normal Boot etc because a hardware change had been detected, at which I selected a normal boot.

I saw 1070(107x10.0) in the POST and in XP's Help and Support at Tools, My Computer Information, System Info saw Speed 1070 MHz.

Flushed with success I rebooted and in the BIOS set:

AutoDetect DIMM/OCI Clk : Enabled
CPU Host/PCI/Spread Spec : 110/37/Off
CPU Vcore Select : +0.05

As soon as I Saved and Exited the CMOS the monitor screen went blank and its amber standby light lit and that is how it has been ever since.

I have tried pressing the Reset & Power Off and Power On reboots but cannot get anything out of it. There are no sounds, no memory checking clicks or any error message beeps.

It would appear that I need to back one or both of these settings off a touch but since I cannot get into the BIOS I do not know how to do this.

Where do I go from here?

John, I reckon that 5x read as 14x that you mention is how the A1400AMS3B the(200MHz) version does it.

Another thought I have had is about the capability of my original memory it is probably only 100 MHz. The 512MB I added myself was from Crucial and is described as Part No. CT64M64SD75512MB 168-pin DIMM PC133.
The orginal memory the machine came with is simply described as 256 MB SDRAM.

An Edit P.S. Having written the above I went back and tried booting up again. This time there was one continuous beep. I pressed the reset and briefly saw "32 MB something" in the top right of the screen before it went blank and stayed blank.
I think my Nvidia GForce MX200 Graphics Card doesn't like the 37 MHz!

I think it is time to use pins 2 & 3 of the JBAT Clear CMOS jumper with the mains power off of course. Who can remember all their BIOS setting?

OK the CMOS settings in the BIOS are back at defaults and I am up and running at 1000 MHz again.

While the case is open I am going to go looking for the Crystal with 14.3 on it and get the Phase Lock Loop info.

..................

OK this Edit is to add the info I have found.

My shiny, oval, aluminum 'cannister' has "25.4F1.B" on it's top and near to it, the black, rectangular chip, with many tiny connector 'legs' along each side has:

VIA
VT1611A
0106CE TIAWAN
18H401F68 C M

printed on it. The C & the M above are inside circles.

You were spot on about a good light and a magnifying glass.
