7800gt don't keep it clock speed

post #1 of 5
Thread Starter 
What could that be??? Since I overclock my CPU I have alot of problem with my video card... If my front side bus is under 250 the card will work but sometimes it will go from its normal speed of 438 to 275Mhz and the application will lag a lot even freeze sometimes. And if I rise my FSB to 250 and higher no 3d application would start at all...

really strange...also since I change my board I notice that my video card is clocked 38 Mhz faster even if nothing is overclocked. it is now to 438 insted of 400 with my old board(a8n-e). Could that be a part of the problem.....?

any help would be really apreciated.

Weird, I dont see how a Clock would drop, unless there's a Voltage issue, which would be moreso the PSU than anything else.

Reset the CMOS and run everything stock, no point in OC'ing if nothing is working

I'll try that...

How can I be shure that the power supply is not defect... My voltage with Asus PC Probe are good and stable. Anyway i'll try to reset CMOS and see what happen...

thanks

When you changed motherboards, did you do a clean install of the OS and drivers or the repair method ???
