a7n8x 2500 overclocking problems

[Paper Tiger]

So I was messing around with overclocking yesterday and was increasing the fsb. My motherboard seems to have issues running 200mghz fsb as it blue screens a lot during game play. I don't know what, I have seriously been trying different settings on and off for a year now with no luck.

Anyways, I was at 193x11 and bf2 crashed, so i upped it to 197x11 and i got an error loading windows that the startup file had been corrupted or something. Basically I had to re install windows and lost all my important data, recovery did not work, rebuilding the boot did not work, repairing the windows installtion did not work.

Anyone have an idea what happened? Did I do something wrong?

Also, the video card was overclocked at 390/360, with pci latency at 64.

My system specs are:
2500 barton
a7n8x rev 2.0
9800 pro
ocz pc3200 1gb dual ddr kit
2 western digital 36g raptors
antec tru 430

was the pci/agp lock on?

There is no pci lock in the bios that I can find.

It's running bios 1008. I've never had this happen before.

Just trying to get a little extra performance out of my rig for the newer games. It was stable for a day or two at 193x11, then I got a blue screen in bf2 and that was the end.

I don't understand why this mobo is giving me so many problems, I know of other people that are running their 2500's with rev a7n8x 2.0 boards fine. Mine just consistantly gives me crap.

that sux, maybe trying turning off spread spectrum just in case. and always prime95 test for a day just to be sure

you're supposed to increase the voltage to at least 1.65 since I think 2500+ chips boot up at a lower voltage? xp3200+ chips booted up at 1.65v so it's reasonable to think that your chip will need just as much juice

Both the desktop 2500+ & 3200+ use stock vcore of 1.65v.

Lets review some OC basics:

What vcore are you now using?

What vdimm?

At FSB 193mhz, does your ram pass memtest86 if run overnight?

What are you CPU & sys temps at FSB 193?

BTW: FSB of 193 was about all I could get out of my desktop (2500 Barton). I had to boost the vcore to about 1.725 or so. But the heat got to be too much. My rig is in a non-AC'd room. With good cooling, I believe I could have gotten higher.
