At stock FSB:

Ambient temp: cool

idle :25-35 spread across 4 cores
load: 42-46 spread across 4 cores (prime95 64 10min)
 
What Vcore? What's your ambient temp? What program are you using to get the idle temps?

Too many uknown variables. Also, idle temps don't really matter and I can tell you that those load temps don't look accurate.

Yeah those idle temps seem way too low. We need more information.
 
I guess I rushed posting this morning as I was late for work and all. I really do apologize. Should have taken my time and maybe posted some pics which I will do tonight. Until then let me fill in the gaps. Its a water cooled system (CPU only). I used Realtemp 3.0 and prime95 64 bit under Windows 7 beta to get those temp readings. Its a new build and I haven't even started overclocking. In matter of fact I disabled 'Turbo' mode. My load temps varied across the four cores something like 42,44,44,46. The ambient felt like 60 F - it was brisk and cool this morning but not freezing. Yesterday we had a heatwave (oppressive and no AC) and the load temps peaked at 52. I tested the cpu under a Thermalright ultra 120 (4 pipe) cooler and the load temps also peaked at 52 but the ambient was pretty chilly in the low 60s. But I'm curious what other D0 stepping owners are getting?


CPU: Intel 920 D0 SLBEJ
Thermal Grease: Tim Consultants 0098 formula
Vcore: 1.200 (I think)
CPU Block: D-Tek Fuzion V2
Rad: XPSC RX360
Pump: Swiftek 655 (variable speed)
MB: EVGA Classified
Ram: OCZ DDR3 1600 8-8-8-24 running at 1067 7-7-7-?

Again I'll post some cpu-z pics tonight ... feels like I'm forgetting something...
 
I'm getting something similar at about 18-21c ambient myself. though I haven't tried a full load of prime.
 
Here are some screen shots to back up my temps:

That's only after 5 minutes of prime... Try running IBT or LinX with 5 passes and see how high the load temps go. Much quicker than running Prime95 for hours.

Idle temps seem pretty good, although it is on stock with Vcore of 1.2v. Hopefully they won't deviate much when you start overclocking.
 
So maybe the temps will go up a few more degrees. I'm just curious though what other D0 920 temps others are getting for comparison?
 
Run the Intel Burn In Test software. That will get your temps up.

4.0 @ 1.175v with HT Idle

I'll post my 4.2 @ 1.25v in a bit.

4.2 @ 1.25v with HT Load
http://i113.photobucket.com/albums/n222/kinhwilliams/421175withHTLoad.jpg

As you can see the heat goes up greatly just by raising a mere 200mhz. Definitely don't think I can run 4.2 safely during the hot days. :( Technically I can boot in to windose fine at 4.2ghz @ 1.75v as well but I'm just not prime95 stable until I push the voltage up to 1.25v. Both of these were done on air btw (see sig) with room temp of around 73f. Oh and Load temps on both 4.0 and 4.2 are with Prime95 "Small FFTs" for 7-8 mins (although I have run them overnight).

4.0 with HT @ 1.16v sure is nice. My temps are about 2*C lower than yours (depending on ambient, of course) but I'm running a C0 at 3.8 and 1.248v. Still impressive to see you hit 4GHz at such a low voltage. It takes me 1.344v to get there with HT turned off.

4.2GHz is the higher end of the spectrum for what you can get air cooling. I've had no problems with this on some boards, but others won't have any of that.

Yah, voltage is pretty low (below stock I think, 1.2v is stock for i7 920s right?) but the heat is still intense! :eek: I see by your sig you have a Thermalright TRUE. Is that about the difference between a regular and a TRUE, 2c? :confused:

Wow, PC_User, you were quite right. Disabling HT does make the i7 run ~10*c cooler. Seems to be the same temp idle but it does lower load temp for sure. Technically this means I CAN run 4.2ghz this summer as long as I have HT off. :)

HT is a good feature to have on. Considering that you can have it on and still run the D0 at a relatively low voltage, I wouldn't turn it off.

I meant that my C0 runs about 2*C cooler than yours. The point is that although most D0s run the same (or sometimes higher) clock speeds as C0s at noticeably lower voltages, temperatures for the most part have remained the same.
 
Ran OCCT For an hour:

This one of the hottest cores:

Ofcourse I have yet to overclock yet but can't wait. I think the D0s have excellent thermal properties. Though I'm only about 7 degrees cooler than a thermalright ultra. Thought it would even be better that the ultra but maybe it will hold up better during overclocks...

I have the exact same batch number and was wondering what memory speed your running along with voltage (VTT, Memory, ICH, IOH, ect...)

I only ask because I am needing insane amounts of QPI/VTT voltage (1.55+) to run thus thing at 21x200 with the memory at 1600 7-7-7-20 1T. I may just get a different MB and or memory if this can not get worked out.

Currently I am running with 1.26v CPU, 1.65v memory at 1.55v QPI. I have not really messed with the other voltages since I am a noob at i7 overclocking.

Thanks in advance for any help!

The following are my system specs:

D0 stepping 920 /w Scythe Mugen 2
Gigabyte GA-EX58-UD4P
EVGA GTX285 FTW
Corsair TR3X6G1600C7G
Corsair HX1000
Samsung SH-S203N
3x Seagate 320gb 7200.10 Raid0
Antec 900
 
I read that if you get a 101 stop code to raise vcore and a 124 stop code means raise QPI/VTT. I am getting 124 stop codes, but also 9c stop codes.

I am just not as experienced with this platform so I figure it smart to ask around before messing with the other voltages more than I have.
 
Using the realtemp 3.00 program, here are my temps on a new d0 core i7 920 cpu with Coolermaster V8 hsf, stock speed 2.66 ghz:
min/max 39c/67c Antec p183 case fans 100%, cpu fan 100% (noisy mode)
min/max 42c/71c Antec p183 case fans low, cpu fan low (quiet mode)

The cpu fan speed was adjusted using a program called epu-6 engine. This came with the Asus P6T V2 Deluxe Intel X58 motherboard.

Do these temps sound about right?
 
d0 920 cpu @ 3.8GHZ with a Zerotherm Nirvana in an Antec 1200 (all fans on high)
40C idle
72C full load running prime
 
His temps seem right on. I get slightly lower temps than that even, but thats due to my heatkiller 3.0, larger radiator, IC diamond, etc. And Im talking about about my temps after playing CoD5 for an hour. Right now, my SLBEJ is only at 29C, and Ive been on the computer for a while. Room temp = 69F.
