I'm not sure whether this is the right place to post this question as it has to do ith overclocking (or rather not-so-successful overclocking), but here it goes:
I have a Gigabyte GA-965P-DS3 rev 3.3 motherboard, 2Gig of PC5300 RAM (@ 667MHz), an NVIDIA 8800 GTS (640MB). Also I have 4 HDDs + 1 DVDRW drive.
The problem is that even the tiniest little overclock (like going from 1.8 to 2.0 GHz) causes the card to switch to x1 PCIe speed from x16. Stock CPU and memory speeds don't cause this. Also, I even connected the card to a separate PSU to eliminate insufficient power as a culprit (even though my main PSU is 560W or more - can't remember right now, but sufficient). I upgraded to a bios that is promised by the manufacturer to fix this particular issue (F11). No use. F12 bios (the latest) - no use as well.
The strange thing is that, when overclocking, setting the memory divider to run the memory at its stock speed or lower as well as fixing the PCIe frequency to 100Mhz doesn't do any good.
It is starting to look as if there is simply no way to get the system to overclock without loosing the video card's speed. The CPU overclocks nicely up to even 2.9GHz although at those speeds the memory starts to be a problem.
I've been unable to find any good info on this problem and it seems as if not many people are really having the same problem. Those posts on different forums were either in German or some othe nordic language or not answered at all.
If anyone knows anything about this issue, please help me.
Unfortunately, I cannot try another video card with the motherboard as I don't have one and have noone I can borrow one from, so that's not an option.
Thanx in advance....
