OK, I think I flashed my backup bios finally, used an older ps/2 kb. I did the alt+F12 and the screen flashed, then rebooted like normal.... Hopefully that was correct LOL!Now, the GOOD NEWS!After I had reset everything to auto from the backup flash I was about to retry all my settings when I realized I had XMP Profile set to disabled!I set it to Profile1 and the SPD now changed to 1866, timings were proper 9-10-9-27, and the ram voltage set to 1.5Run OCCT = NO ERRORS!!!! YAY! (10 min test) Maybe I'm not supposed to be on XMP (but I know this specific ram supports it), but it works finally!Prime95 = No problems either (really short test though)Now, vcore tends to vary between CPU-Z, OCCT, and Gigabyte's own utility, Easy Tune 6 (which I recently updated) Which one do I trust? And should I just set it to 1.21 like dazz recommended?

I've been spending all my breaks reading up on this stuff.Looking at other well-known hardware sites it seems other users are having troubles running at 1866 with these new revisioned SB boards. Though Corsair states over and over this RAM will work at 9-10-9-27 1.5v 1866mhz, I'm just not seeing it. Not sure how much time I'll have tonight to swap a stick out, or run memtest... first priority is to get that dang backup bios flashed. Also, I think I know what may have caused my initial boot to fail a few days ago. I changed the command rate to 1T, and that's when the bios reverted to the backup bios. So the PC will boot and load Windows (and FSX works) with 1866 and 2T but I can't pass stress tests. With 1333 and 2T I can pass stress tests. I hope it's a RAM issue and not a flaky board issue. I'll be out of town for a few days, so I really do appreciate everyone's help in trying to get me up and running!!!Thank you! :Hug:

I have been running the Corsair Vengeance at 1866 99924 1t 1.5v since January. Works also with the new B3 P8P67Dlx. They might not be the same ones however.Mine are labeled:CMZ8GX3M2A1600C8Also I have upped the volt at 1.525 to account for the Overclock. Stable as a rock.Pierre

Told ya in my earlier post to set the rams on XMP, mine do support XMP and they are set on it.OCCT need to run for a full hour without errors.Trust CPU-Z for the voltage.

Yeah must have missed it... a lot of suggestions in the thread!I will run OCCT later this evening for a full hour and then report!Thank you!!

Do not trust CPUZ fopr voltage (sorry Allain, it is not right for these boards) trust ET6 as I think somebody else mentioned in one of their posts. :Whistle:

Cool beans on the memory! The voltage reading in CPU-Z is broken again since the release of the B3 boards (this only applies to Gigabyte as far as I know). The HW Monitor tab on EasyTune6 is a great place to watch your CPU voltage and RAM voltage as it plots it and allows you to graphically see any dips or spikes. Just click on the CPU or DRAM buttons to scale the graph appropriately. If EasyTune6 isn't within 0.01 or 0.015v of what you set in the BIOS, let us know - but otherwise it should be good.

No problem...

Ok, while in FSX it varies by about two 100th's (.002). Honestly it's still set at auto. Is the Vtt that I need to change to 1.21v?
