Someone with 3924A390 i7 920

[iTravis]

Guys I have a question regarding my temps since I asked quiet a few people and got different answers. I have TRUE lapped with 2 Ultra Kaze 2000rpm push/pull but my i7 920 D0 temps reach over 90 at full load when running LinX @1.36V (room temp is around 28-29C since it's hot these days). Some people say it's normal but others say it's really high, I'm trying to keep it under 85C at full load and I did remount, reapply thermal paste many times but still got the same result. I just took my heatsink off yesterday and I noticed there was a dark spot under the base, it looks like the MX-2 thermal paste got burn or something. So what your take on this?

@ 4.2 Ghz? Temps seem a bit high to me... Perhaps your heat spreader has bad contact with the chip.
Your vCore is too high for 4.2 IMO.
And regarding the thermal paste - really odd! Can it be some 'faked' MX-2? Or it might be some left over from the old TIM that was 'absorbed' by the CPU.

Just a bit high? You mean over 90C at full load? As for the chip I don't think I got a really good one that's why I need that much voltage, try to bump up VTT or QPI voltage but still no help. As for the paste, how do you know it's faked? I got the MX-2 from newegg.

Your temps seems abit high. Have you tried rotating the TRUE 90 degrees ?

On my mb/cpu mounting the TRUE with the fan blowing up/down resulted in way lower temps.

Hm..I've been told that my temps are ridiculously high at full load, so what you guys are saying it it's normal to have such temp? Just a bit high since my ambient temp is high? And yeh, I already did the North/South config, no difference compare to East/West.

[iTravis]

sry im new here, how would i go about uploading my results? i noticed you have to do it through a web addy or url how do i go about that?

Just upload through any image host sites like Imageshack or Photobucket.

There are big individual differences in temps on i7 cpu's. I have 2 W3520 that differs around 10c on equal oc. On air (TRUE with single 2000rpm fan) I have seen temps approaching 90 in LinX at 4.3 and 1.28v on the hottest one.

So it's normal to have such high temp? I have Turbo on so the first core is always the one with highest temp, I've seen the highest it can reach is 93, the rest highest is 90. Some people said that's not good for 24/7 but I think in reality we never use that much CPU load anyway, yet they sweat me a bit that make me consider changing the cooler. By the way my idle temp average is around 48 for the first core and 45-46 for the others 3.

i know im new here but 4.2ghz with 90+C temps is no way good even under load. you should be getting 70-75c tops with a TRUE. Is your 920 a D0?
because your voltages are way up there for 4.2 also.

@imo, what is your CPU batch?

Woah... I have nearly an identical batch as yours:

3914A114

4.2 GHz, 1.275 vcore, 1.300 uncore - Prime95, and LinPack stable.
(Marginally stable with 1.250 vcore.)

I doubt I'll be able to hit 4.8 GHz with 1.388 vcore.
I'm only on air, so I'll need to wait until winter here Chicago.
Then I can take my rig outside in -10F for some serious sub-zero air-cooling - which "theoretically" should be better than room temperature water-cooling.

any one else

[CryptiK]

What, did you buy it and the IHS was not attached?

[Chicken Patty]

or did he remove it?

I noticed core 0 stays anywhere from 3 to 4c higher than the rest is this normal?

Mine: Batch 3910A313 (4.2Ghz @ 1.35)

[road-runner]

Just picked up a 3912B353 a little bit ago, fixing to drop it in under water and see what it does...

[road-runner]

Seems to be ok, a quick run just to get it stable for crunching...

[Esajuppeli]

My i7 920 D0 (3851A262) clocks like this (Every voltage may not be exact minimum):
3360Mhz 0.99V
3500Mhz 1.08V
4000Mhz 1.25V
4300Mhz 1.38V
4600Mhz 1.52V

Max. 24/7- clocks are 4400Mhz HT Off, 4450Mhz HT Off. I'm using watercooling with two 360 radiators, Eheim 600 pump, 12mm/1,2" hoses, 6x Noctua NF-P12.

[Chicken Patty]

road runner, we have a very similar chip. I dont know if I can go lower on vcore, probably can just don't want to stop crunching to shut if off. THese are my crunching settings too! Load.

no man

removed it...killed my mobo but have been waiting 3 weeks for 2 mobos so i can run them

they both work, confirmed by jcool
