Core i7 Vdimm/VTT Graveyard :D

[saaya]

1.4 min, 1.55 max for QPI/DRAM Vcore
1.9 min, 2.2 max for vDimm
2.0 min, 2.2 max for vPLL

During all the week end, testing P6T Dlx, and no problems. I'm under Swiftech GTZ.
I'll go on next week with SS/DI and i'll tell you what's happening.

cool, thanks for the feedback!

Dinos, 1.5v realy safe for regular usage? what board you using anyway?

weve been running 1.55 uncore aka vtt for a while without any issues so far...

Dinos,
Fugger had a 965 down to -95 if memory serves. It was in one of the first two i7 threads he posted about. Don't know if that will apply to the 920's too. Just thought I'd mention it in case you didn't see it. I'm pretty sure that was the number, but I'm pretty tired right now. Kinda taking a break. I'm trying to get mine booted for the first time. The butterflies are churning too.

theres barely any scaling going that cold tho... you can bench at -15 and get almost the same clocks as -75 :/
tried the intel, giga and asus boards, all the same :/

Guys,
I got a questiuon on this. Anyone know where this 1.65v figure came from and how it was arrived at? Why 1.65v? I'm just curious what the reason was for it, and why. I know that the JEDEC was 1.5, but they were running higher than that before, but with this chip it has thouse warnings and they put stickers on some boards covering up the RAM slots. It worries me because these things seem to be doing fine, but that number is still there making me wonder.

ask intel
thats the figure they came up with... its 10% of 1.5v... 1.5 plus .15 = 1.65v...

Has anyone hear had problems running high speed/volt ddr3 on their i7 mobos?
Is the initial startup voltage 1.65, or the default for the ram? Did you have to run some slower ram first to set volts, and then pop in the high speed ram?

havent heard a single thing so far, all sticks seem to boot up just fine

AFAIK, Intel actually released "safe" voltages...1.65V was the highest reccommended for a stable system running 24/7.

I didn't have any trouble with mine. I'm running the Eclipse with missmatched Kingston DIMMs (2x 2000MHz 9-9-9-24 & 1x 1833MHz 8-8-8-24). They worked first time on auto...and I'm currently benching with them at 1600MHz 7-7-7-18 1T with 1.75V.

These i7's are really nice with memory it seems. They don't seem to need near as much voltage as on the older x48/P45 chipsets.

yeah, we hit 2200 32m stable with only 1.7v vdimm on BloodRage last week, i dont know how well it clocks on BlackOps and other x48 boards, but DEFINATELY not to 2200 with 1.7v ^^
and its just a regular kit, not handpicked, and its not even samsung but micron d9gtr i think
