UnOfficial Asus Rampage II Extreme Thread

[Cookiesowns]

Anyone has issues with vDROOP on the Rampage II extreme board? Both on the QPI and the DRAM, if i set to 1.65 it usually runs at 1.644.... =(, now i force it to 1.66 and guess what 1.65, and my pc is running snappier than ever. 1504 bios.

1720 cas6 and 2050 cas8 so far and i havent pushed vdim over1.65 or pushed qpi over 1.42
not mush time to play but lookin great so far

Nice, SPI32M stable?

Droop is worse on software than reality.

I measure Vtt at the CPU socket, and got 1.21v idle / 1.19v load. Vdimm there was no droop at all under load and voltage was almost exactly what was set in BIOS. Short answer, the software is wrong.

See below:

On another topic, I did some Vcore, Vtt and Vdimm measuring behind the CPU socket to get an idea of real voltages with LLC enabled since it was bugging me how much it seemed to over-volt on load.
I don't use LLC normally, but when benching it helps control things a little more accurately. I was also curious about Vdimm so I measured it directly at the Dimm slots.

CPU Vcore

LLC On

BIOS Set = 1.28750v

Idle:

CPU-Z = 1.280v
Everest = 1.270 - 1.277v
DMM = 1.29v

Load:

CPU-Z = 1.280v
Everest = 1.316 - 1.323v
DMM = 1.30 - 1.31v

Vtt

BIOS Set = 1.2750v
Everest = 1.224v (idle) / 1.197v (load)
DMM = 1.21v (idle) / 1.18 - 1.19v (load)

Vdimm

BIOS Set = 1.577v
Everest = 1.568v (idle) / 1.548v (load)
DMM = 1.58v (idle & load)

Seems the board actually does increase vcore by 0.02v under load when LLC is enabled. This is not good behaviour, it should not change at all, or ideally, droop around 0.01 - 0.02v.
Gigabyte implement a 2 step LLC system where you can have intel spec droop (LLC off), moderate droop (level 1) and slight/no droop (level 2). This is a much better system IMO and Asus would do well to
use a similar system. The vcore should certainly not increase under load.

Vtt is well below BIOS set voltage, idle and load is slightly lower than everest states.

Vdimm is pretty much what you set in BIOS, which is higher than everest reports and does not change from idle to load (I tried this at a few Vdimm settings).

Nice, SPI32M stable?

never ran SPI32M
but i did 2 full passes of memtest
had em 24/7 cas6 1720mhz i'm sure they got alot more to give
they restin now usin the trident 2k bbse set
once the supercomputer thing is over i'll be able to push
i got my loop in finally lol
doin wgc @ 4.2 most i hit is 62c ambient 23c
