Opteron 165 High load temps, Not case or compound related...

[NHjrMonarchs7]

Hey all,

I got a 165 opteron and the idle temp is pretty decent usually from 30-33c, but on load the temps sky rocket to up to 60c. This processor is still on stock volts. I have check my AS application and lapped my heatsink, I have been reading that the IHS and/or the diodes conductivity with the IHS may be bad or not flat. Do you think that this could be the case? Should i lap the IHS or remove it? Input please!!! This CPU is at 2700 on stock volts...(temps do not change when i put it back to stock)

My old Opty 165 that was at 2.6 GHz would run at 55 C while running dual Orthos, stock volts.
What does the coretemp say the temps are?
If you run it at 1.8GHz, it probably should not be at 60C. What's the stepping?

Its an LCB9E stepping, within seconds of starting dual orthos, core 1 is at 60-62c, core 0 is at 46-56c. This seems way to high.

I just tried on stock speeds, its only core 0 49, core1 54 now. That is still to high.

My temps were measured by speedfan, which should be cooler than coretemp. You might try a temp utility that measures at the CPU case and see what that says. IIRC, the AMD specs for operating temp are taken at the CPU case, not core

if your coming from your 3700+ diego in your sig to a opty 165. there will be a difference in load temps from the two. your temps are on the same lines as mine were when i was on aircooling so you have nothing to worry about there. i used a scythe mine w/ 120mm yate loon with the same overclock and volts in my sig now. dual core chips just get higher load temps than single cores.

Good to know, thank you, My stepping is actually lcbqe0712upaw

For dual-core AMD chips, the reported core temps are crap. According to AMD, they have a +/- 15° C reporting accuracy, so just ignore them. And geezerman is right, go by the cpu socket temp, which is Temp #1 in SpeedFan. As long as your socket temp is ~50-52°C, then you're fine, and that's coming from someone who's anal about their cpu temps.

Awesome, thanks, I actually did decide to lap the IHS...That puppy was everything but flat...The outsides of the ISH wore down much quicker than the center of the IHS, in fact, i need to get more sand paper today to finish it up. There is still silver in the middle, the outside is now copper. I am going to give the IHS and my ninja a good lapping tonight. Ill post with the results.

My Opteron 165 was running at 66 degrees celsius under load (Prime95 x 2).

I thought it was waaaay too hot, so I did some reading about removing the IHS.

I popped it off, but it made no difference, and I even lost 65mhz off my overclock. So, do not remove the IHS whatever you do.

I'm curious as to how much your temps will drop by lapping. I probably should have gone that route.

I was running the chip at 2665 before I took the IHS off, and now I'm at 2600mhz, both at 1.425v.

Hey Sick Beast, thanks dude, I def will take what you say. I have gotten pretty lucky with this chip it seems, i think I can get her pretty high. Like i said 2700-2800 with stock voltage so far. I just hate seeing high temps. So with your load at 66c have you had any issues?

Well, I'm at the brink of stability.

I had to back down to 2600mhz; we've had a heat wave here in Toronto, and it was stable in 25C ambient, but not 33C.

It's been exceedingly difficult to maintain a stable overclock. Even if I only run at 2500mhz at stock voltage, my chip still runs in the 50's under load.

I'm glad I was able to help you out; I'm pretty upset that I popped off my IHS. If you do it, keep in mind that it's *hard* to do, and that it's very easy to damage these tiny transistor things around the core. I scratched one and I have a feeling it's why my maximum overclock went down.

The IHS removal guide I read did it on a single core Opteron; with the dual cores, you have a far smaller margin of error. The knife just slips as you're doing it.
