Hi there,

I have recently upgraded my Mobo to Abit AN7 Mainboard Socket A, nForce2 Ultra400/MCP2-T, 8X AGP

I have an AMD XP 1800+ processor

My mem is Crucial PC 2700 512 MB

My GPU is an XFX 5700 ultra (128 MB)

I happened to notice that by default I was only running my processor at 1150 Mhz (11.5 *100).

So I upped my FSB to 133 to get the proper 1533 (11.5 * 133). (266 being the designated FSB for the 1800+).

Ram is set to run at 333 Mhz

AGP @ 66 Mhz

Is this as good at it gets without Overclocking?

I'm guessing I can't push my FSB to 166 (333) and match the Ram (333), without having to change the multiplier to 9 (or there abouts). But will the CPU support this?

Are there any issues with my FSB running at 266 and Ram at 333?

and Finally is 66 still the standard rate for AGP slot?


many thanks

I think that your FSBs for processor and ram are intact. But I am not too sure about the GPU. I think, it must be more than 66 MHz, but I may be wrong.

QUOTE Is this as good at it gets without Overclocking?
Yes, these are the correct default settings.
QUOTE I'm guessing I can't push my FSB to 166 (333) and match the Ram (333), without having to change the multiplier to 9 (or there abouts). But will the CPU support this?
Possible. Just try to select a lower multiplier and then reboot. It will either accept the new multi or it won't(i.e. it will just keep the default x11.5 multi)...no harm done
Depending on your CPU's type/model, you might even be able to just raise the FSB to 166MHz without changing the multiplier, although i wouldn't recommend doing that if you're using the retail/boxed heatsink & fan that came with your processor.
QUOTE Are there any issues with my FSB running at 266 and Ram at 333?
Stability-wise, no....it should run just fine.
However, running your FSB and memory frequency asynchronously(i.e. at different speeds) will actually decrease performance on NForce2-based motherboards, so i suggest you set your memory frequency('DRAM clock' to '100%' or 'synch' (or just 133/266MHz if none of the aforementioned options is available) in BIOS.
QUOTE and Finally is 66 still the standard rate for AGP slot?
Yes, 66MHz is the default clockspeed for the AGP-slot.
Overclocking it wouldn't make much sense, either, since you would not get any noticable increases in performance.

Ah, many thanks Greyhound - you are a scholar and a gentleman

I guess what I really need is a new CPU, but alas no $$$ for such an extravagance

I always feel a little guilty mentioning this on official forums, but so far no one at AMD seems to mind people talking about overclocking. If you've got a Thoroughbred-B 1800+, you stand an excellent chance of being able to up the FSB to 166MHz. (You can check this with any CPU info utility like CPU-Z or WCPUID; family 6, model 8, stepping 1 is a Thoroughbred-B.) You might have to up the voltage a little, but you could still manage it on stock cooling assuming your temps are reasonable now. Thoroughbred-Bs are wonderful like that. Just remember, on stock cooling it's really not a good idea to go above 1.7v or 1.725v, so, uh, don't.

Of course, overclocking's done at your own risk, blah blah blah. If your temps seem reasonable now, the only real risk you face with overclocking is losing your BIOS settings via clearing the CMOS. Speaking of which, if you decide to try this and it fails, just clear the CMOS (unplug it, pop out the silvery CMOS battery-- in your case, it's near the bottom right corner of the motherboard-- and count to ten slowly, pop it back in, plug it back in, and boot up). You'll lose your BIOS settings (and of course the time), but that's all. (If you really don't want to lose them, sometimes turning it off, waiting, then turning it on again while hammering insert helps on nForce2 boards.. some kind of default settings thing, it's worked on a few boards I've seen.)

Ah my luck is definately running out my 1800+ is 6,6,2 model

The Nvidia system util reports my CPU voltage at 1.075. isn't that a bit low?

CPU Temp 60 C degree

Having looked at the Model 6 data sheet I can't see where my defaults are for my CPU... why are these details such a secret?

<SDA>, can you please tell me where I can find these utilities?

No-go, then
Around 1.9GHz is possible with some Palominos(AXP model 6), but you would need very good cooling and a good deal of voltage....
QUOTE The Nvidia system util reports my CPU voltage at 1.075. isn't that a bit low?
Thats just incorrect. Period.
Try using a different hardware-monitoring utility like MBM5 or Speedfan(search on google) and/or check your voltages in BIOS(usually in the 'PC Health status' or 'Hardware monitor' menu).
QUOTE Having looked at the Model 6 data sheet I can't see where my defaults are for my CPU... why are these details such a secret?
Default voltage for all (desktop) Athlon XP model 6 parts is 1.75V.
The appropriate specs *are* documented in the Datasheet' ">http://www.amd.com/us-en/asset...nd_tech_docs/24309.pdf, p.31(Chapter 7), table 8

Also, a solid connection to a higher power (and I'm not talking about a good PSU ) is a must when OC'ing a Pally.
