Here we go. Yet another AM3 working on M2N32-SLI deluxe.



This validaiton after a 30 minute Prime95 stress. Granted I could let it run for a few hours, but i'm getting tired.

Regarding temperatures

I must say that I do not trust the temperature readings for Athlon II or Phenom II CPUs on our M2N* boards. The "CPU" temperature in the BIOS seems to be too high (possibly 10C?) and I know for a fact that the temperature reading for the individual cores (as can be read by HWmonitor for example) is too low; With my watercooling and light CPU load I can get temperature readings that are below ambient temperature, something which course is impossible.

AMD specifies different max temperatures for different CPUs. Generally the recommendations seems to vary between 60C to 75C. Temperature is not the only thing that matters though, increased voltage together with higher temperature is what causes CPUs to degrade more rapidly.

One word of caution; our motherboards where built when the most demanding CPU consumed around 125W and high-end CPUs could not be overclocked very much. Todays high-end CPUs are far more demanding when overclocked. You might want to be a bit careful of how far you push your CPUs especially on the weaker boards.
I noticed a few days ago that HWMonitor has some kind of reading (or estimation) of CPU power consumption. That might be useful.

The temperature has dropped below -20C now, so I did one more benchmarking session with my 555Be and M2N32 Ws Pro board:

I managed to OC the CPU past 5GHz now :-)

Dang, man, where do you live? That is mighty cold!!!

You must be setting some records with those speeds.

This 965BE setup I have is incredibly sensitive to ambient temp. I had noticed that if I place my hand 6" above the stock cooler, the fan spins up and the CPU temp increases almost immediately. Withdraw my hand and it comes back to "normal".

As a result of that observation, I removed the PSU from the case and opened up a few more baffles on the front of the case. The PSU is now hanging outside of the case. The net effect of these changes is that the temps running my MP3 to AAC encloding tests, which run the system at about 50% duty cycle, reduced the CPU temps by 4 degrees C. I was shocked that it made such a difference. By consequence, the fans are also quieter.

BTW, I'm running HWMonitor 1.17. I did not see anything that looks like CPU power indicator.

I live in the middle of Sweden.
The temperature has dropped to below -25C now. I guess it might end up below -30C tonight.

I tried to do one more session with the M2N32 Ws Pro board and a Sempron CPU, but it didn't work out so well. I experienced so called "cold bug" issues with the motherboard, that is the hardware stops working properly because of the low temperature.
I have a few records for watercooling, but compared to what the professional overclockers are capable of with liquid nitrogen, it really is nothing to brag about.

A benchmarking table/stand might be just what you need then. :-)

I'll check once my benchmarking rig has thawed a bit more.

ok i got a awesome deal from my friend, i will be adding another 9800gt to my rig. just wondering how well these m2n-sli deluxe handle sli. how many have tried it so far?

I dont know the difference (performance) between m2n32 and m2n, but if i am right 88gt=98gt, so with SLI, will be a good upgrade (see my sign )

Good Holidays anyway, to all of this club

nice to hear, i just found out though the one he has for me is the 1gb, i have the 512mb, so now i got to sell mine or just buy another 1gb card.

Well, IMHO makes sense to do an SLI when you already have a GPU, you add another GPU equal and "recycle" the system. Buy two cards for SLI no longer makes sense to me .. how much you spend and how much it costs a GTX460?

How are your temp now?

I had stock cooler on 8800gt (not single slot) and I had too much hot inside case (I hadnt 2x120 on top, now I have - my lianli is "upset" with GPU on top).

Feel free to ask everything
