**Gigabyte GA-X58A-UD7 OC-Tips-Bios-Discussion Thread**

Hey Sam, that's a little high drop, on ud4, when I set 1.64v in bios, it read 1.630v in ET6 and when set to 1.66v bios, ET6 reports 1.648v. I found that ET6 reports are actually the real value used.

BTW, did you try to play with the QPI/PLL? I read it could help in stability but you are only using 1.100v

Cool, I will try this Vdimm.
I didn't change the QPI/PLL at all to test the effect on stability. It has been damn stable, but I'm not pushing this CPU yet. I will try this for higher OC .

EDIT: Did change ...
It was a big jump from 1.616v to 1.648v for adding just 0,02v (from 1.64v to 1.66v BOIS sett) .
But I'm happy as long as the real Vdimm is under 1.65v. Is it really? I'm not really sure after seeing that dramatic jump.
EDIT2: (I see it is flipping between 1.632v to 1.648v on Idle, maybe it is after all).
Anybody has measured the real max-Vdimm for 1.66v on this MB yet?

Now I have some extra voltage on NB, and "one notch" extra on SB, PCIe, and QPI/PLL. With QPI/VVT=1.28v
Probably would need more VVT for the next jump, or pushing the RAM (Uncore/IMC), tho.
How does it look? should I adjust more/other stuff ?
