You may just have a bum CPU. Some don't like OCing.

Your ram may not be able to handle even a small increase, too, but that's much less likely.

And 'ow' with the colors.

Congradulations on getting your system to OC. Sounds like you got a decent overclock out of it after just a little elbow grease.

As for the colors, if you browse around the forum you will notice that nobody posts in colors. It just kind of clashes with everything else. It is akin to writing in all caps...just bad manners I guess. Not to offend you or anything though, I know that you did not post like that to be offensive.

How did you get your board to accept anything that high. I too have a TUV4X, and the manual says it will only take upto a 1.2 cpu.


EDIT:

Okay after checking the Asus site, I see they changed the chipset to Via instead of the Apollo.

Wish mine would go that high too.

doesn't VIA make the appolo?

if i really try i can get my celery 900 up to 1.2....

uh...if you break down the ASUS motherboard code this is what my board works out to be:

TU - tulatin CPU support
V- via chipset (via 694T)
4X - AGP video multiplier/support
(it's accually 4x pro, but i'm not tottally sure what "pro" is...)

and apperently theres supposed to be a - WOA after that for "without audio"

and i've also flash my bios to the newest version (1005), so that might have something to do with it..

Hi Q-Frost. Sorry to hear about your o/c problems.

Before I get started, let me state that cooling is not the cause of your problems!

I have a Tualatin 1.3 Celery, Silicon thermal gunk & stock intel cooling, on a Gigabyte 60XT-A (Solano 815EP B-stepping) and managed to get it overclocked to 128FSB 99% stable with no voltage change. 99.99% stable at 125FSB @38C. I'm sure it would have been rock solid but the crappy mobo would not allow a voltage change.

Anyway, I had loads of problems to start with because of some strange incompatability with the memory. I originally had to use a Gigabyte utility called 'EasyTuneIII' to get overclocked otherwise the machine would not post. Using a setting in EasyTune to automatically find the maximum overclock possible, it went right up to 126FSB before locking. Strangely enough, the CPU seemed to burn in and became more stable after a few weeks of use. Eventually 128+FSB was possible with no voltage change!

On occassion I would twiddle with the Bios settings and eventually stumbled on some(apart from default) that the machine would boot with. These were 124+FSB and 3-2-2 5/7 memory(locked to same speed as FSB). I also found a great increase in stability over 117FSB by using the dividers to keep the PCI bus(IDE HD drives) as close to 33.[3]mhz ending up on the low side of 33.333333mhz. I tried several different brands of memory and amounts and there definately was a BIG difference in stability. Could not get any overclock with 512MB in the BIOS regardless of brand. Some would overclock at the specific settings I mentioned earlier. Others would not overclock in the BIOS at all but were fine at ALL O/C speeds using 'EasyTuneIII'.

So my advise is: try 120 or higher FSB, set the PCI divider and use 3-2-2 5/7 memory settings or even memory on Auto. If you can, up the CPU voltage by 0.025v at a time and go as far as 1.65v max.

If the machine cannot get back into the BIOS then clear the CMOS and start again.

Downloading the latest BIOS update and Flashing the ROM might help.

Try disabling the onboard audio as sounds started going a bit strange on my mobo above 110FSB, whereas my Aureal Vortex card works fine even at 128FSB.

If EasyTune works on your machine do not use the demo version of EasyTuneIV because it saps about 10% performance.

As Forge mentioned earlier. "You may just have a Bum CPU".

Good Luck
