Not all of them, some 975X motherboard also has huge vdroop such as my previous ASUS P5WD2-E Premium.

define 'huge' bro...my dq6 drooped about 0.024-0.0026v...is it huge or tiny one...set in bios 1.400, windows (CPUZ, Speedfan) 1.376...looks huge but of course 0.024 looks like tiny one...so not sure whether it's huge or not...

but the problem is
975 is a chip which don't really can clock..

i hve a DFI 975 mobo
which cannot make higher frequency

975 is good pairing with a higher multiplier processor, due to most 975 can reach high fsb like most 965 does.

Nope, 975 can go only as high as 400++ FSB only. Suitable for high multiplier.

Opps, I write it wrongly. I mean 975 can't reach high fsb like 965 does. My bad.

My new proc..

C2D E6850 @ 4ghz 500x8 1.5vcore (intel stock heatsink)
Gigabyte P35T DQ6
2x Kingston HyperX DDR3 @ 1500mhz 9-9-9-24 2.0vdimm
1gb HIS ATi Radeon X2900XT
Non tweak Windows XP sp2



see the temp? this proc is damn cold

35c only ???? 1.5vcore + intel stock heatsinks

Impossible! Is the readings wrong?

edited pic....? lowest i've seen is 52 on idle wif stock HSF and compound... unless u use dried ice or other cooling chemicals it's impossible to get tat low...
how did u do tat....?

irenic, try install your Gemini see how cold it can be. Also 4Ghz @ 1.5v is MADNESS.

hmm...this proc seems good for cascade benching.....4ghz at 35c.....5ghz+ would be possible i guess with -70C. But right now DDR3 performance isn't any better than DDR2 platform based on those PI time.

The proc defaults at 3ghz so 4ghz at 1.5v is reasonable.....my e6600 @ 4.3Ghz needs 1.57v...so its roughly the same but this proc definately show lotsa promise of its low temps.

I wonder if the temp reading is correct or not. Run Speedfan to double confirm or Gigabyte probe software.

Is there any reference to say how high these CPU's Vcore can SAFELY go up to? As shown in the packaging, it was stated 1.35v max. Does that mean if OC more than 1.35v, warranty void?

1.5v is reasonable for air cooling?

Intel couldnt care less if you overclock with 1.35v or more, they have no ways to check how much vcore you have pumped if to send back for RMA.

@irenic
I see that you sold your Gemini, then can't test anymore, getting what next?

air cooling is best to stay at 1.4v - 1.5v.....with phase change or cascade cooling, can go above 1.6v - 1.8v....depends on how cold you can hold the temps

No prob with warranty....u can pump in 1.8v and kill your proc, send in for warranty and there is no way Intel could check coz all voltage settings is done on the mobo itself. nothing is stored on the proc.

i didnt do anything.. i even used the stock thermal paste that comes at the bottom of intel stock fan

as u wish~!!

idle temp with EIST enable (stock speed)


i just bought a new set of wc..

Gawd, that really is cold even with 1.2v on stock cooler @ 2Ghz. ._. Guess with WC, maybe can easily reach 4.5Ghz.

What WC setup? Apex Ultra?

OIC, then how come high performance RAMS has warranty up to a certain Vdimm? e.g. 2.2v for DDR2. Would they know if we OC more than 2.2v?

Goshhhh stock thermal paste + stock heatsink + 1.5vcore 35c what a nice proc
