Ok, I reached 2.8 GHz, but there's one little hickup...my PWM temps went through the roof. Got all the way up to 80*C after running Prime95 for a bit . My CPU hasn't topped 52*C yet...haven't had to increase vcore or decrease the multi so far...

Hueristic, good point

Well come to find out that the lapped NB heat sink (42*C) is ~10*C cooler than the unlapped one (52*C). Since the rigs are setup almost identically this makes for a good comparison.
Omega Supreme, sorry I completely forgot to reply to your post.

Thank you for reporting your findings. That just goes to show that lapping really does improve temperatures. How did you manage on removing that square yellow pad from the chipset cooler?

Good luck

Decimate, what kind of airflow setup do you have in your case? You may have a dead spot of air near your PWM that is causing the high temperatures during full load....

Sorry for the double post

Good luck

This is definitely the problem because I have a massive CPU heatsink (Cooler Master Hyper 6+) that's directed upwards because it's impossible to screw the damn thing in if you face it toward the back of the case. It's ok, though, because there's a huge vent at the top of the Silverstone TJ09 case. This leaves the PWM, which sits next to the CPU socket on its left, in a bit of a dead spot...I'm considering flipping the rear case fan so that instead of sucking hot air out, it's blowing cold air in, but I loathe having to open my case up again...I guess I'll get around to it eventually.

For now, though, the PWM gets up to 81*C when running Prime95 but no more than 62*C when running 3D applications. I ran through 3DMark06 with the Opteron 185 at 2.8 GHz and came up with a score of 11202.

I think this is the end of the line as far as OC'ing goes without me having to go back into the case and shuffle a couple of things around to get that PWM some more cooling. On the bright side, there's plenty of room left in this Opteron. I'm pretty sure I can break 3.0 GHz easy as long as the RAM is able to keep up...

On a side note, I looked up PWM temps on the Abit website and this is what appeared:
Quote:
"PWM" is a circuit on mainboards to convert the voltage level from power supply unit to provide specific voltage to components (ex. Provide CPU with core voltage). We know that CPU could be the hottest component inside a PC system, and we always care about the heat dissipation of it. Actually, the PWM circuit is quite hot too; especially when CPU is at full loading, large current passes through the PWM circuit and was converted to necessary CPU core voltage. Some ABIT boards show "PWM temperature" on BIOS setup page and Windows hardware monitoring tool. This provides users possible hottest temperature inside the PC chassis, and check whether the air conditioning inside the chassis needs to be enhanced or not. When CPU works heavily, the CPU temperature could be around 60 degree C; nevertheless, the PWM temperature may achieve 70 degree C or even higher; depends on the design of thermal convection. The safety limit of the PWM temperature is about 120 degree C, however, we strongly recommend improving the air flow and heat dissipation inside the PC chassis once it rises to 100 degree C.
Er...so apparently my temps are fine?

There's a few useful types here.

Decimate, if the information Abit is posting is correct then I would say YES you are fine. According to what they said you are 20C below the average limit which is probably good. Still though it wouldn't hurt to improve the airflow of that area in your case.

Good luck

This is the one.
http://www.harborfreight.com/cpi/cta...emnumber=93983

That first link had 3 laser ones of varying quality. but the cheapo one is good enough for our uses. Weird thing is it is $13 online and the specs are different the the specs of the one I got. but it looks the same.

Oh ok I saw that one and looked right past it not knowing what it was. I instantly wanted the gun type.

Thread Starter 
Decimate, if/when you get around to playing with fan orientations in your TJ09, try flipping the two top fans from exhaust to intake, and your CPU heatsink's fan to blow down (towards the video cards). This might seem really counter-intuitive, but I use the TJ09 as well and through a lot of testing of fan configurations, I discovered that using the two top-side fans as intakes dropped my load temperatures by about four degrees Celsius. That will also stimulate a lot of air movement in the PWM heatsinks' area, which should helpfully improve temperatures.
