Z68XP-UD5 GD2 nstability = excessive overvoltage

[Deathchant]

I have great news!

I took the celeron out and put the 2600K in.
After post -> all LEDs = out!

After 1,5 hour of torture in prime95:


Conclusion:
- 2600K not broken
- motherboard not broken
- GD2 led is just an oranje led that goes either on or off. After the post, before windows-startup, the GD2-LED goes out together with the rest.
Decreasing voltages in the bios does not make the LED-status change, this happens AFTER the post.
-  Spontaneous reboots were no instability-signs. Some gigabyte motherboards do this after a bios flash or after changing a lot of settings and saving it to the cmos.
- I think the stripes and artefacts in-screen and the not-wanting-to-post-to-bios issues was really a bios-F1-issue. I really don't know what else it could be, I excluded everything now. On this site I can see that it is supported since F2:

And no, I am not willing to flash back to bios F1 again The torture....
So for now, the quick conclusion is that my system is just fine now.

Hey, great news mate. At last all sorted. I wasn't sure of the status LED myself and so couldn't be definitive about how it worked. Now we know it will be easy next time.

Thanks for all the concern Dark Mantis and Allan!!

I've enabled the XMP profile (DDR3-1600 @1.65V @9-9-9-27), 2600K running @3.8GHZ and I did some prime95 again, only for a short while but no errors.

Well, I've tweaked W7 64bits that much that it fully looks like it is XP

I have played Crysis2 (without DX11 pack and high textures) and everything is stable. Man, it's good to have a fast PC:

I agree! Always great when it all works out in the end. Makes it all worthwhile.
