No Overclock Success with axp 2200+

[matt00926]

Im using the following

AXP 2200+ 266 fsb 1.8 ghz 1.6v
abit nf7 2.0 400fsb support
corshair xms 256x2 pc3200 2-2-3-6 @ 2.6v

ive gone from anywhere from 2.0 ghz to 2.25 ghz. ive tried the following

1.7v @ 2.0ghz
1.75-1.8v @ 2.2-2.25ghz


13.5 x 166, 13.5 x 148

if i try different multipliers i cant even boot into windows

the other times i o/c all desktop apps are stable, its games that freeze, and prime95 gets to about 20 seconds

is their something in bios im missing?

all fail within 20 seconds on prime95
yet on stock speeds it can go for hours with no errors

i purchased the cpu about a year ago retail, and i can get the chip up to 2.25 ghz and the ram up to 333fsb boot into windows pretty stable until i do anything 3d like gaming\prime95

Um, you have the AGP locked at 66 mhz right?

And 2.2ghz is quite ambitious for a chip that isn't really known for it's overclocking ability. If you were running a mobile barton or something it'd be different, but 2.2ghz is quite a jump in clock speed for a 2200+,.

Also check your temps since you're having stability problems whenever the CPU is hit with any heavy processing.

agp is set to 66, im not sure if its locked though, is their an option to lock it or something. and temps never go above like 50's maybe highest was 60 which for an amd i think is pretty safe, the shutdown temp in bios is like 75, and i have a bios from december

hmm, well first check that your latest bios is actually useful to you. If it doesn't include any usefu updates then revert back to an old bios to see if that fixes anything. If the AGP is set to 66 then you're fine. Those temps are high though, anything nearing 60 is a bit too high IMO. That's probably not the problem but I would reseat your hsf just for good measure. The first thing I would do is start in really small increments, either from a low starting point (a point that you are sure you can boot with) or from a high point and just work your way to what you feel is the max @ your current vcore. At that point play around with the vcore and try again. Keep doing that until you get a no-boot, then drop back down to your last bootable configuration and prime it.

Your vcore values seem a bit too high to me although I'm not very familiar with the 2200+ but I run my barton @ 2.2ghz with 1.575 vcore and could probably get away with 1.55.

If that doesn't work and you're not satisfied with the overclock I would just spend $85 and pick up a barton 2500+, they're great overclockers and inexpensive as well. A Barton would also allow you to utilize your Corsair XMS which at this point is nowhere close to its potential.
