Crippled by crosshair bios 1602 and waiting for update + win 7
-edit updated correct nb speed.
Updated.
1055 down to 1.100V now. 1.150V looked stable.

Ok cool. I assume you're using y-cruncher to determine your stability? For some reason Prime95 blend finds errors quickly; y-cruncher cannot.
Really? You're having better luck with Prime? I've actually been meaning to test all the various ones on Thuban. I've so far played with y-cruncher, Prime95, and OCCT.
Yeah it finds errors quickly, I don't know if it has to do with round off checking or what. But the blend option finds memory instability quickly.
Failed at 1.100V. Looks like 1.150V is the ticket for my wafer. That's pretty impressive though.

Quick OC, just tested with Cinebench R10 and R11.5, will test stability and max OC when I have the time
1.4xx VCore (will check later in bios, I forgot VCore in Windows is bugged)

I hope 8 hours of Prime Blend is enough.
vCore idles at 1.416V and fluctuating between 1.44 and 1.452V on load and you see what value is set to (1.403125V), lol.
I'm writing 1.44V, since it seems that almost everyone writes the value which vCore is set to, not the load one.
HT is fluctuating, too, but most of the time it's around 230, regardless the fact I've set it to 228MHz.
Actually, after 8 hours of Blend, C'n'Q is disabled again...

And here's a screen with 700% memtest from a previous run, didn't wait it untill 1000% reached. The HT seems to be 1 MHz down on that particular screen, 'cause of the fluctuation.

Other bios settings
NB Voltage: 1.38V
VDDA Voltage: 2.74375V
HT Voltage: 1.35V
SB Voltage: 1.20V
NB1.8 Voltage: 1.8V
I'm not sure if all of them and their increased values were needed, but that are the settings atm.
I see another 1010MPMW in the table, very good cpu frequency, even if it's on 32bit and chilled water, they seem good :)

That's why sometimes prime95 and linpack will fail instantly and y-cruncher won't. And sometimes y-cruncher will fail before prime95 and linpack.
It depends which part of the system (CPU or memory/IO) is more unstable.
As for as temperature goes, linpack seems to run the hottest on Core 2 and K10 if it is tuned correctly. (because it is just THAT well optimized)
But the exact opposite is true on Core i7 when HT is enabled. y-cruncher runs the hottest simply because HT allows it to use both integer and floating-point units at the same time (thus stressing everything).
I bet core damage will get even higher :DQuote:

This does sound like a very interesting program. I'll try it later (when my i7 rig finishes its current task - which will take a few more days).
From my experience, pure CPU/execution unit programs don't produce the most heat. That's because the execution units are only a small portion of the processor.
To achieve maximum heat, you need the right balance of computation, memory access, and branching to be able to stress every single portion of the processor simultaneously. (execution units, branch prediction, instruction reorderer, cache, memory controller, etc...)
So far, I have yet to see a single program that can do this. I'll see if core damage can do it. :D

At 1.15V, full load is about the same as 1.35V's idle. (~23C) That's about -10 or -15 or so degrees.Quote:

Here's mine, just got my ram from rma so had finally the time to test stability. I had ran Prime95 blend at custom to finish each FFT length test at only one minute and finished all test in just under one hour and still going as I'm writing this.
Last time i tested prime with my x6 (3 weeks ago) fried my board running at 4.2GHz at 1.575v, i guess i was feeding too much volts trying to find stability on which the problem might have been my ram.

From the screenshot, my idle temps shows 33c but actually it's about 23c as i ran hwmonitor after i ran prime ;) lame excuse

Updated. No, I haven't tested wall power, but I can do so if you wish. I do have a watt meter. What kind of configuration are you interested in? I'll have to use a discrete GPU as this isn't a GX board, which would probably be what you'd use in an actual HTPC. I can test it with any combination of the following you'd like:
- (2 Max) Radeon HD 5850 OC
- Radeon 4850
- Radeon 3870
- GeForce 8400 GS

@ridney: I'll need 8+ hours for the stable chart. For now you're on untested.
Maybe time to put in the first post that people should NOT report the core temperatures, it's the CPU temperature that are interesting...
Some posts here where they are at damaging levels +62C at the CPU (cpu temp approx core temps + 13C !)
Don't want people to fry their cpu:s...
Edit: Maybe also ask people to write down full load voltage instead of idle voltage....
