| Ultimate OC Stress Test
said by AgentGOD  :Description: Linpack by Intel(R) is an extremely stressful program that will put even the most powerful X86/X64 CPU in the world at its knees. Load temp under Linpack will be up to 22*C higher than the competing software Prime95. This program will make usage of Linpack easier and more practical. Keep in mind, use this program at your own risk. By using this program, you agree that neither I nor Intel shall be responsible for including, but not limited to: burned up CPU, fried motherboard, spontaneous room temperature increase, hair loss, or mental stress. Benefits of using Linpack: 1. More accurate than Prime95 Small FFTs/Blend. 2. Takes less time to tell if your CPU/RAM is unstable than Prime95 (usually something like 8 minutes Linpack vs 40 hours under Prime95). 3. Use the same stress-testing engine that Intel uses to test their products before they are packed and put on shelves for sale. Benefits of using IntelBurnTest: 1. Simplifies usage of Linpack. 2. Direct output of results to the screen. 3. Simplifies the process of selecting a test size to use. 4. Better appearance. »www.xtremesystems.org/Forums/sho···t=197835

LOL! |
it worked for a few seconds then stoped working
temp only got to 48C that is 6 C more |

Maybe it is not for AMD CPU's??? I guess LOL |

Definitely a great program!
This found my previous OC as un-stable... An OC that was 8+ hours prime95 stable in less then 10 minutes...
Cannot beat that!

| Yah, it will bring mine to its knees when I venture above 3.6 GHz @ stock NB/VCORE/DDR/FSB voltage settings. I would definitely trust Linpack over memtest and everest for determining system stability. It's an added bonus that it will produce errors relatively quickly.
I noticed you were using Real Temp to monitor your core temperatures. I downloaded it and tried it out and found it displays a temperature 10 degrees below every other core program I have tried. I found in several OC forums that it is one of the few monitoring programs that displays the Wolfdale core sensor information accurately. So, I'm glad I tried it out! My idle temps are 31 - 31 and I am about to find out what my actual load temps are with another Linpack run.

i dont know anything about this Intel burn in test but the end-all stability test (sans GFX card) has been OCCT since the 2.0 beta was released
»www.ocbase.com/perestroika_en/in···Download
it uses the Prime95 25.x multi-threaded codebase but supposedly has further enhancements to increase CPU stress. Its generated graphs are fantastic, too. |

| Ender3rd ,
See in your screenshot of core-temp, it says your TJMax is 105c, that is wrong...
said by Intel Corp :
45nm Desktop Dual-Core Processors
Intel Core 2 Duo processor E8000 and E7000 series - 100°C
45 nm Desktop Quad-Core Processors
Intel Core 2 Quad processor Q9000 and Q8000 series - 100°C
Intel Core 2 Extreme processor QX9650 - 95°C
Intel Core 2 Extreme processor QX9770 - 85°C
»www.anandtech.com/weblog/showpost.aspx?i=478
Make sure in your real temp settings it says 100c for accurate temps!
Trust me I have OCCT v 2.0.0a I was passing that with flying colors... Prime95 v25.6 build 6 x64 passing for over 8 hours...
Failed IBT in less then 10 minutes....
If you think you are stable, try IBT, you may be proved wrong...

Glad you spotted that. I set both programs to TJMax = 100c and they both agree perfectly. Idle is reading 37c 37c and a LinPack 5x run shows both cores running between 53c - 54c. Those look like pretty reasonable numbers for the modest air cooling I have applied (Dynatron P985 in a zero pressure case).
Thanks for taking the time to point that out. I never would have spotted it!

| Interesting. My system was Prime95 stable for hours. Failed IBT within 10 minutes too. Had to back off the FSB a notch or two. That solved it.

I got IBT v1.6 stable @ 3.8 Linked & synced with memory @ 1900 MHz.

Thanks for the link. I've been stable (as far as FreeBSD is concerned) at 356x9, but I'd like to see if I can dial in the voltage to drop the temps if possible.
I'm also curious to see just how quickly it will fail at 400x8 on this Q6600 In FreeBSD, I can induce failure with mprime (read: prime95) within about 3-5 minutes. This should pick up the failure even faster I guess. Curious to see how bad it is, though, and if I'm truly stable at 3.2 (356x9).

| said by Stray Bullet :You can do 400x8 No, really, I can't.
I can't even do 400x6. This CPU does NOT like a fsb > 356 for some reason. Before you say it, it's been hashed out in a few threads - the memory is DDR2-1066 (PC2-8500) so it's not the limiting factor. Nor is it the motherboard (Asus P5K-E, the previous board - an Asus P5B - also had the same "cut off"). I've thrown 1.5 (and I think more at one point) at the CPU, it simply will not run at >356x*.

| said by Somnambul33t :anyone had success with this on Vista64 yet? It won't run on Vista PE...I get an error about an illegal instruction immediately after running it.
*edit* Nevermind. The problem is that Vista PE needs the 32-bit IBT, and when run with the "maximum stress" it probably tries to allocate most of my 4G of RAM and promptly dies when it cannot.
If I run it on 1/2, it still pegs all 4 cores, but doesn't crash (at least due to the memory allocation ) |

said by Stray Bullet :You can do 400x8 Yikes, with IBT running, my core temps were 63/63/57/57 (max, usually a bit lower) at 356x9 (1.2625 Vcore). That's nearly 10C higher than what I see under typical max load on this box. 
I'm trying 400x8 with the same Vcore and see what the temps are (and obviously if it passes heh).
Then what the hell, I'll try 425x8. Suggestions for Vcore?
