This just started happening a day or two ago, well in it's current form at least.
Occasionally, when my PC might crash while playing a game, it would boot back-up and performance would be slow. I somehow discovered that my PCIx16 port was being scaled down to x1, resulting in poor performance. I figured out that by loading optimized defaults in the BIOS and then redoing my overclock, I could fix it. Well, apparently no longer. Now, I can load my stock settings and all works fine. PCIx16. But, as soon as I overclock the CPU, it immediately drops the PCIEx16 down to PCIEx1. Any idea's what's going on? Am I not getting enough power from the PSU and so it's scaling it down? What's going on?
Gigabyte DS3 (Rev 3.3)
E4300 (When OCed: FSB 300, V.Core 1.4)
2 Gigs G.Skill DDR2 800
GeForce 8800GTS 640meg
Windows XP
Fortron 400W (Max 450W) PSU
So far, I've determined that it's unrelated to how much voltage I give. I set the FSB to 250 without any voltage modifications and it still scaled it down to 1x. As well, I've changed nothing with the PCIe slots in terms of speed. They've always been set to auto and always worked fine. I also manually set the speed at 100 and it still scaled it down.
This is getting really frustrating. I'm ready to give up on OCing and just buy myself a better, higher clocked processor.
Thanks.
