My fans are mislabeled. The one labeled chassis is actually the CPU fan (mini-Ninja w/80mm fan using SpeedFan/PWN) and the other two fans are 120mm case exit fans (using manual fan controllers/Fanmates) and yes, when encoding, this machine is a bit loud, but in "low power mode", with the fans at min (and the CPU fan off), it's very quiet.
In my O/C testing, I find that doing and encode with x264_64bit using an AVS source with
QTGMC to deinterlace an interlaced source provides a serious beating on the CPU and memory, so much so, that I don't even use Prime95 anymore for stability testing.
fwiw, it seems like your voltage is high for a "mere" 20%, but then, all chips are different...what does your NB Freq show in CPU-z?
Ah OK, that might explain why your CPU is much cooler than mine then. What fan do you have on the mini_Ninja though, as I guess a 80/92mm would spin faster anyway to generate the same amount of air? I used to use one of those and found it OK but I'd have thought the Xigmatek HDT-D1248 would do a bit better, or at least as well. Looking at these results, it seems it's not the best heatsink and works better on 65mm Kentsfield CPUs than 45mm Yorkfield CPUs but I'm not sure which the Athlon II X4 is closer to
http://www.xbitlabs.com/articles/cooler ... 84_12.htmlNB and HT are both at 2000Mhz at default and I set them to 1920Mhz when testing the overclock.
I did have to use 1.456v on the Biostar board with the TRUE to get this CPU to 3.22Ghz, so it does seem like I've just got a poor performer here. Not that this would be a problem if it weren't for the temps. Even if the Xigmatek isn't quite as good as the TRUE, I'm having trouble understanding the much higher temps I'm getting with it:
(I'm being generous and assuming the recorded figure I have with the TRUE is Core and not CPU, I'll see if I've got any fuller records somewhere).
Idle: Xigmatek CPU 37, Core 27 @2.8Ghz(800Mhz)@1.36v(1.10v) vs TRUE Core 24
Load: Xigmatek CPU 62, Core
[email protected]@1.36v vs TRUE Core
[email protected]@1.456v
so either way, that's 22c higher at .1v lower!
I wonder if I didn't apply the TIM properly but I used (the last of my) Arctic MX-2 compound and applied it by filling in the channels on the HDT base and then applying two short lines, as shown here
http://archive.benchmarkreviews.com/ind ... mitstart=5I was using Arctic Silver with the TRUE but I don't think that should make much difference and the MX-2 should perhaps be better if anything (or safer at least, not containing any metal). It'd be a major pain removing and reseating the heatsink as it would require disconnecting everything and removing the motherboard from the case to get at the nuts, so I obviously don't want to do that if the heatsink is performing as good as can be expected but if it's majorly not working properly then it's best that I fix it, even if only to minimise temperatures at default clocks and prolong the life of the CPU. I'll have to order some more MX-2 to do this but I might as well get some anyway as I'm sure I'll need it for something else.
