Hello. I have an older computer set up for my 9 year old daughter to run her games on. It's an AthlonXP 2500 with a gig of PC-3200 on a Biostar Nforce 2 mobo and an ATI all-in-wonder 2006 Edition, which I believe is a 9600 GPU. Well, being me, I had the urge to try to overclock this machine with a modest bump from 166fsb to 200fsb, raising the cpu from 1.8Ghz to 2.2Ghz. Well it's totally stable running anything that is not 3D, but when something does, it drops back to the desktop and gives an error saying "the graphics driver failed to initialize". So to test I set it back to 166Mhz fsb and it works totally fine again. Any thoughts or suggestions would be greatly appreciated!! Thanks! :D
 
If you can try checking if the agp bus is locked to the right frequency... ie 66 mhz... that is most likely your problem as the multiplier causes the agp freq to increase when the fsb increases
 
Thanks for the reply. I will check that after work today. I thought that the agp bus ratio would be auto set... I should have checked. (doh) Thanks again and I'll let you know.
 
OK, that wasn't it either. It was already set to "auto" in the bios. I set it maually to 66Mhz and it still will not drop into 3D. Totally fine back down at 166fsb. Weird...... :confused:
 
I believe there was the Nforce2 and the Nforce2 Ultra. Nforce2 Ultra is what officially supported 200Mhz FSB. Could just need a little push in the volts to become stable. The Board have any volt adjustments?
 
Hi... there is one AGP voltage adjustment. I'll have to try bumping that up abit. Thanks for the suggestion.
