I have a Compaq Presario 1625 laptop that I want to upgrade the processor on and not sure what the options are. I was also wondering if the "2x as 6x" trick so you can run at least a 400 (6 x 66) processor on this motherboard would work as well. I can't find any info on the manufacturer of the motherboard. Thanks. The specs on the motherboard are:

Bus Ratio setting range is from 2.0x to 4.5x

CPU core voltage options are 1.2V / 2.2V / 2.45V

Bus frequency setting options are 66.6 MHz / 66.0 MHz

This is the information from CPU-Z:

Are you running the latest BIOS ROMPAQ SP11490.exe (336.47k) F.0A (07/14/99) Release Date: 1999-08-02 and Battery Controller/KBC Firmware Update SP15238.exe (702.09k) Release Date: 2000-08-09 Version: 1.11?

The 2x = 6x is only for CXT core (Model 8 and Model 9) CPU's, so you'd have to purchase a new CPU.

Are those the only VCore options you have? (EDIT - looks like they are, though there might be some undocumented settings available as well.) If so, a K6-III-400/450 (Model 9) 2.2V/3.3V running at 6x66MHz for 400MHz would be the fastest CPU you could install...assuming the BIOS will setup this CPU properly, and a BF2 pin is available.

If you can reach 2.0V Vcore or lower, a K6-2/III+ CPU can be fitted to extend battery life.

Note- I think they meant 60.0MHz and 66.6MHz, not 66.0 MHz and 66.6MHz.

EDIT - Looks like BF2 is available. See ->

CPU #5 - ??? ;)

Thanks for the info. I have installed all of the ROM updates for the motherboard off of compaq's website. Is that good or bad? I am planning on getting a different processor off of ebay for this laptop. I just needed to know what processor would work if any at all. The documentation for the laptop motherboard off of compaq's website says 66.6 MHz & 66.0 MHz. They may be wrong but I was just quoting the manufacturer. What is a BF2? I didn't see anything on the link you put saying anything about BF2. So if I got a K6-III-400/450 (Model 9) 2.2V/3.3V running at 6x66MHz for 400MHz, would I put the clock multiplier on 2x then to get the 6x. How would I find out if my Bios would support this CPU? Just install the new CPU and turn it on ???? Thanks again for any info you can give me. I know my way around computers okay pretty well, but updating processors I don't have alot of experience with.

Get your CPU here -> http://www.jlmtech.net/catalog/index.php' ">http://www.jlmtech.net/catalog/index.php

ROM updates are good.

BF0, BF1, and BF2 are the pin names for the Bus Multipliers on a CPU. Some only have BF0 and BF1...thus their bus multiplication is limited. Your board seems to have all 3 (S1-4, 5, and 6) so you should be able to set all possible multiplier combinations...not just the ones that are listed in the table (it is missing 1.5x, 5.0x, and 5.5x). On a CXT core K6, the CPU will recognize a jumpering of 2x as 6x automatically.

As for the BIOS knowing about the CPU, that will be a cr*apshoot unless you can find someone that has tried this before successfully on your particular machine. It might work just fine, display incorrect information but run just fine, or not boot at all until you set a configuration that it knows about. The last BIOS date is pretty recent, so there is a GOOD CHANCE the CPU will be recognized correctly.

If you can set 2.0V or lower on VCore, a K6-2/III+ CPU will give you an even bigger boost in performance. These CPU's have an on-die, full speed L2 cache...making your notebooks motherboard external cache an L3 cache. These will also help conserve battery life...which can always be of benefit.

VCore on your machine is set with S1-1, 2, and 3...and again, not all switch positions are mentioned in the setup document. Since you can set as low as 1.2V, there is a GOOD CHANCE that you can set voltages in-between 1.2V and 2.2V. There are some rarer flavors of K6+ CPU's that run at these lower voltages (I've seen 1.6/1.7V advertised...was there a 1.2V as well??).

Thanks for the info. Is there a different between laptop and desktop kIII 400 MHz processors? I may just go with the KIII instead of the KIII+ so I don't have to worry about screwing up the voltage. I don't think I understand the multiplier part though. Would I have to set the multiplier to 2x on my motherboard using the dip switches then? Or does the processor do it automatically to get the 6X. I don't know where on the mother board to test how to get 2.0 volts to run the KIII+ unless anybody can help me out with that. If I can get 2.0 volts then I would prefer to go with the KIII+. Thanks

The biggest reason I want to upgrade the prccessor is so I can add a DVD rom. The DVD rom supposedly needs a 350MHz processor or better.

I did some searching on ebay and found some K6-III 400 MHz processors but they say right on the chip 2.4 volts. My motherboard says it has 2.45 volts as an option. Will 2.45volts work for a 2.4 volt K6-III cpu.

Nope...the CPU does not know what it is mounted in. That's why I have a K6-2/+ running in my DFI Tower!

Yes...you set the CPU Multiplier switches for 2x...the CPU will do the rest.

A K6-III running at 400MHz will use 10.80A@2.2V and 12.40A@2.4V Vcore.
A K6-III running at 450MHz will use 12.15A@2.2V and 13.50A@2.4V Vcore.
A K6-III+ running at 450MHz will use 8.50A@2.0V Vcore.

So there is a BIG difference in power savings...and it will help make life easier on your VCore regulator as well.

If you have access to a DVM, you can measure VCore without a CPU installed. The readings will be close, but not exact, as you should really have a load on the supply for a proper reading.

VCore S1-1 S1-2 S1-3
x.xxV Off Off Off
1.20V On Off Off (Set as Default)
2.45V Off On Off
x.xxV On On Off
2.20V Off Off On
x.xxV On Off On
x.xxV Off On On

When you say DVM do you mean digital volt meter? I got one. I can't keep the processor on it and change dip switches as I'll fry the current CPU won't I?. Lets say hypothetically I took the current CPU out of the mother board and wanted to test the various dip switch (????) options the manufacturer does not give. Where am I actually testing on the motherboard with the processor pulled? Also what is the procedure for doing this. I take it I turn the pc on when trying to test the voltage right?

So can the K6-III 400MHz processor run on 2.2 volts or 2.4 volts? The processor chip has stamped right on it 2.4 volts. I'm a littel confused on this? Thanks again for all the help as this is all starting to make alot more sense.

K6-III 450 MHz processor on Ebay' ">http://cgi.ebay.com/ws/eBayISA...&rd=1#ebayphotohosting

Yup on the DVM.

It depends on the currently installed CPU, and the current that the VCore regulator can supply. You could either over-voltage the CPU, or pull too much current from the regulator.

To measure, you can look around for the VCore regulator, and measure off of one of its legs (find the correct one). You can also find out what pins VCore is on the Socket 7, and measure (carefully) off of one of those.

The K6-III came in both flavors, so you have to read which one you got. The one you show is the 2.4V one, and he will use the most power (12.40A@400MHz). It depends then if your VCore regulator can supply that kind of power or not, which was not mentioned in the specs. You can figure it out by checking into the VCore parts themselves, or by writing COMPAQ and seeing what they say.

My DFI can support 10.0A on VCore, so the + series CPU is just the ticket.

Hmmm...Just saw you have something called Power OK swithches...I'm gonna bet you have to set those to match as well...

Per your other post -

VCore S1-1 S1-2 S1-3
x.xxV Off Off Off
2.10V On Off Off (Set as Default) <- corrected
2.45V Off On Off
x.xxV On On Off
2.20V Off Off On
x.xxV On Off On
x.xxV Off On On
x.xxV On On On

If this is the case, and the CPU marking confirms this, then a K6-III+ should just drop right in...it will run at 2.1V just fine (though if you can find a 2.0V setting, that would be cool).

Your BIOS may have motherboard sensor measuring built-in...what does it say?

K6-266 MMX
(Little Foot - Model 7)
January 6, 1998 - {$268} 321 pins

Socket 7 32KB data (2-way)
32KB instruction (2-way) 8.8 million

I would not understand why they set the thing to 2.1V (1.2V?) when it is a 2.2V CPU...

Thanks again, you've been super helpful. So you think compaq mislabeled the maintenance guide off of there website saying that default vcore is 1.2v? If they mislabled it and it was actually 2.1v, then I could go witha K6III+ which would be even better than running a K6III. Would a 2.1v K6 processor even run on 1.2v ???? I actually went in and changed the voltage from the supposed 1.2v to the documented 2.2v for the current K6 266MHz 2.1v processor. It definitely runs a littel better. I ran a program called cpumark and I went from 16.3 before the voltage increase to 17.7. So I had a definite increase by changing the voltage from the documented 1.2v to the 2.2 v setting. I also changed the power OK voltage to match the core voltage setting. I also tried changing the multiplier from 4.0x to 4.5x on both voltage settings and the pc would NOT boot up. So I left it at the default 4.0x.

I don't feel comfortable hooking a volt meter to my motherboard so I will go with the K6III 400MHz 2.4 volt processor and just run it at the documented 2.45 volts on my motherboard. I would think that would be fine. Unless you think my default setting on my mother board is definitely 2.1 volts instead of the documented 1.2 volts. Thanks again.

Again...does your BIOS support "sensor monitoring"? You would be able to monitor things like temperature and voltage, etc...

If not, Everest can monitor these (assuming that the motherboard has sensors to begin with), and can also tell you alot about your machine. The latest Beta Build 254 also has the K6+ CPU MSR dump added (pats self on the back for suggesting it to Fiery ). The Computer Sensor page will tell you just what the voltage is when you flick the switches.

http://www.lavalys.hu/pre/ever...ever..._build_0254.zip' ">http://www.lavalys.hu/pre/ever...esthome_build_0254.zip

If the CPU could run on the 1.2V voltage, it would surely pull more current to make up the difference. I highly doubt the thing would boot up though. That's the reason I think it was a misprint (along with the 60/66MHz one). Not sure why you couldn't change the CPU multiplier, but OK for now.

Printed on the CPU says:

AMD K6
AMD-K6/266ADZ
2.1V CORE/3.3V I/O
A 9822EPGW
1997 AMD

I ran all of the Bios updates on the Compaq website but Everest still said my Bios is 6/09/98. I hope that will be fine. Around the CPU there is a cream colored holder that says "lock" on one side and "open" on the other. I haven't tried to pull the CPU yet but appears to be reomovable. I ended up setting my voltage core back to the default 1.2V which is more than likely "2.1" volts since you think my pc would not even boot up on 1.2v. Plus when I drop from 2.2 volts to the marked 1.2 volts my cpu mark # drops from 17.7 to 16.1. I would think that if I was going from 2.2 volts to an actual 1.2 volts my cpu bench mark # would drop much lower. I am trying to find a K6III+ 400MHz processor and then run it at 2.1V. Otherwise a K6 III 400MHz processor would be fine and run it at 2.4V.

Do you think the K6III 380MHz processor would be fine as well. I figure setting the multiplier at 2x which the CPU will run at 6x and 6x66MHz=396MHz. Which is over the 380MHz on the chip. It would be nice to go with a 380 MHz chip since it's a 2.2 volt and would run cooler than a regular K6 III 400 chip.

Also, do you think a K6 II 400 MHz 2.2V chip would be fine? If I went with a K6II chip I would not get the L3 cache right.?

I think I am starting to understand all of this and just about ready to decide on the right chip to upgrade to.

One last thing. Would a K6II or K62+ 450 or 500 MHz chip work for me. I know I could NOT get anymore than 400MHz out of it based on the 6x66MHz max capability but still wondered if it would work fine at 400MHz.

I see somebody is selling a K6 266 ADZ 2.1V CPU on ebay so it must be removable.

K6 266 2.1V ADZ CPU' ">http://cgi.ebay.com/ws/eBayISA...1&rd=1&ssPageName=WD1V

Thanks again,

Yup...

A denotes the 321-pin CPGA package, so it is removable. D represents 2.0-2.2V VCore, and Z represents 0-85'C Temperature range.

See -> http://www.amd.com/us-en/asset...t_ty..._docs/21049.pdf' ">http://www.amd.com/us-en/asset...nd_tech_docs/21049.pdf

In this case, Everest must be incorrect (re: BGA).

Try for the + series CPU if you can. It will be much easier on your VCore regulator as I mentioned earlier. The difference between the 2+ and the III+ is the on-die L2 cache...the 2+ has 128K while the III+ has 256K. I'm using a K6-2/+ 450ACZ running ar 6x66MHz for 400 MHz in my DFI, though I'd like to step up to the III+ as it would be the most CPU I could run in the machine.

The K6-III/380 would also work and has the on-die L2 cache, but again, it will use more power.

QUOTE I'm using a K6-2/+ 450ACZ running ar 6x66MHz for 400 MHz in my DFI It looks like you answered my question on running a faster chip at a slower speed is possible. You have definitley gotten me to where I feel pretty comfortable on choosing the right proccessor to upgrade with. Would you rate running at a lower power such as a K6II+ 400/450 better than having the L2 cache in a K6III380 and running at 2.4 volts. I would think running at a higher voltage and getting the L2 cache in the III series would be best but I am just learning all of this so I'm not too sure.

What do you think the chances of my Phoenix System BIOS Date 06/09/98 working with a K6II or III chip? That right now would be my only limiting factor as the voltage is not an issue with 2.1/2.2/2.4 options.

I also read about this: PowerTweak 2.0, it turs on the K6-2+ extra advanced features.
Orphanlaptops' ">http://www.orphanlaptops.com/mp983.htm

I also figured out how to remove the chip. Just had to finally decide to push the screwdriver a little harder to get the chip to snap and slide over. Then the chip comes right out very easily.

Thanks again. Without your help I would not have gotten this far.

The + series CPU's contain the on-die L2 cache as well.

As for turning on the CPU options, let's get the thing installed before we go there. That will be the easy part.

Yup on the CPU removal. Just make sure the lever is fully up before installing the CPU, and make sure to align the pins properly (it only fits one way). It should drop right in with no trouble, and latch just as easily. Does your CPU have a fan/heatsink on it now? How is it cooled?

The BIOS should recognize that an AMD CPU has been installed, it's just whether it will understand the Multiplier properly and give us the speed we desire. One possibility is that it will display properly and run properly. Another is that it will display incorrectly, but still run properly. We won't think about not booting at all.

QUOTE Does your CPU have a fan/heatsink on it now? How is it cooled? The CPU does NOT have a fan on it. Ther is a system fan about 3 inches away from it on the back of the pc. There is also a square aluminum chunk the same size as the CPU and about a 9mm thick that sits on top of the processor and then attaches to a 12 inch by 4 inch piece of metal to dissipate the heat.

My CPU is locked in place by by prying with a screwdriver into the "locked" side of the socket which moves the CPU over a few millimeters. To remove it you pry with a screwdriver in the "open" side of the socket.

I'll try for a K6III+ 400/450 MHz otherwise I'll get a K6 II+400/450 MHz.

Thanks for all your help.

That's right...you have that "heat spreader" thing I saw in the manual. That should be sufficient to keep the CPU cool.

Interesting mounting method for the CPU...just be careful when you pry!

What size motherboard cache do you have? Everest should say under the Motherboard Chipset section.

Make sure you look for the + and not the "P" CPU. The P-type (0.25µm process) is not as power efficient as the + type (0.18µm process), and was the predecessor to the + CPU.
