Windows 7: win7 reinstall

Could be a few things going on?

First, it could just be a bug in cpu/gpu-z. If you want to find out run 3DMark, then switch slots and run it again. If the results are the same in either slot, then it's probably just the bug they're talking about here and you can ignore cpu/gpu-z: DK 790FXB-M2RSH - pcie @ x4 instead of x16 - DFI Club Global Support Forum

It could be your bios getting twitchy on you... it certainly wouldn't be the first time I've seen a DFI bios spit out crazy random settings. See if there's an update for you: DFI LANParty:The Best OC Platform! Overclock, Motherboard, Intel, AMD. As you're probably well aware, it's no small task setting up a DFI bios properly.

Lastly, that slot could be bad... but unless you're going to go SLI it's not going to impact you as you have a spare.

Thx for the reply.

Looking into my bios i noticed that it is NOT updated as i thought it was, so my first task is to update that in the morning.

As for the first pci-e slot i think it's bad, i've had nothing but solid play on the second slot...if it goes i only have 1 left and i'll know it's time to get a new mobo...lol, thank goodness for 3 PCI-E x16 slots.

I've also thought about it possibly being my PSU, so i'll have to check that as well.

I've left the overclocking to a minimal untill i can figure what's up.

Use the guide in my sig to update your drivers and buy the retail copy - it will be more stable.

I know this thread is old...but i thought i would post an update as to what the problem was...1 little RAM timming off...that's it...stupid I know!
