They never make clear which prime95 test they used. There are 3 torture tests, small fft's. large fft's and blend. The cpu temps during the small fft's test is 2 to 3C higher and much more consistant than the large fft's test, which produces more system heat less cpu heat. If you graph the blend tes...

Nice #'s, what do they mean?

Excellent post Burcakb, very clearly shows how an excellent psu can fail to run an A64.

Sounds like you will enjoy the comparing the capacitors of the A64 and p3 board. The p4 800FSB board is very similar to the p3 board.

My personal rule of thumb, 18amps of 12v, 20 amps for videocard with molex, more for top of the line video, more again for over clocking. These are minimums, buy the most 12v power you can afford. The A64 and modern video cards take most of there power from the 12v rail nowadays. Older spec psu's wi...

I also have an nv silencer on a nvidia 6800gt, and it was money well spent. It is much quieter than the stock solution. A much smarter purchase than the crossflow fan in my opinion. It also removes the gpu heat from the case, and on my chaintech a64 board helps cool the nf3 chipset.

You are definatly going for overkill. The stock fans 2 x 120 and 1x 80 are very quiet, and undervolt nicely. There is over 2 sq ft of ventilation on the case. Temps are barely above ambiant. If you are concerned about a particular hot spot on your board, you can position the exhaust of the hard driv...

I'm just guessing, but more than likely you have a dh7-cg stepping, and msi wrote a new bios algorithm for temps because the co steppings temps read much lower on the same bios. If you had flashed the new bios on your old board, you would have seen the same thing happen.

It seems to be common to A64's maybe because the use so much 12v power. Some times resetting to fail-safe defaults, and reconfiguring helps, some tiimes a flash to a new bios. If those don't help some hot glue or silicone applied to the chokes can stop the resonance. (At your own risk of course). It...

Just another bump in the correction problem. I have a thermister on the side of my cpu that reads of 43.4C and the diode currently reads 70C with a correction of -26 that would indicate my temps(d) = 46C . It was my understanding that a thermistor on the side of the heat spreader would read a minimu...

My experience is that the tempurature of over volting hurts more than the voltage helps the overclock. Of coarse water will help that, but I would worry about the life of the cpu at over 1.7v.
Let me know what happened to your block. Too thin jets?

That explains it , thought the 2.0# was a typo. And 70's is uncorrected,44 corrected. I have a chaintech, 70-80 is normal, thats why the correction is so big (-26) Low pressure effects would be balanced by the high pressure side.

Don't feel to bad, I had the same problem with my very different result. If it makes you feel better, your corrected cpu temp is higher than mine!! More seriously, the modern hsf (heat pipes?) may have to be so powerful that idle temps approach ambiant. Since we have the same cpu, running at the sam...

Your temps are not as wonky as you might think Ed. The very fast changes are to be expected with the in-die diode. Try speed fan graphing, it will probably show much more fluctuation.
