Dual Core Opteron Temps...

[NightshadowUK]

So at 2.65GHz with 1.375v (BIOS) I get around 62ºC full load (dual Prime) - does that seem about right?

It's just I'll be going for 2.8GHz+ on Monday but I don't wanna fry anything...

Seems high that mate, what cooler are you using? Is it all in a case with low airflow?

[NightshadowUK]

CPU HSF: Akasa Evo 33 fitted with an 80mm Sharkoon 2000 turned up to max using the lil fan control thing.

Case: Akasa Eclipse-62 kitted out with 2x 120mm Sharkoon 1000 front and rear, as well as another 80mm Sharkoon 2000 blowing down on the PWM area.

I might try an ACF 64 Pro...

Seems pretty high but it is on air

Had my Opteron 146 (on a ThermalRight XP 120 with Sharkoon 1000) at around 52 full load @ 2.7GHz during summer, so that's rather a poor showing by your CPU.

i wouldnt wanna run it long term anywhere over 55 at load personally


buy a better cooler then continue the overclock

First opty165 I got was exactly like that. It went as high as 60 degrees even on low voltage while dual priming and as I checked the core temp I noticed one core was actually 12c higher than the other core which seemed to have pushed the overall cpu temperature. I returned that one and got replacement now cpu temp stays around 50C. Core temp difference is now like 5C. From what I've gathered it's known problem and some people say it's due to bad installation of IHS on AMD side. It seems some later 06xx batches are affected by this problem. Only solution that I know of apart from returning is to remove IHS and install cpu cooler directly on your cpu core but doing so will void your warranty. So if you can return your cpu and get another one.

For a comparison my Opteron 165 at 2.2GHz (1.35v) is 40C~42 C at load (prime).

If you load it at stock (2.0GHz for a 170) what is the temperature like?

M/B could be supplying extra voltage you are not aware of. What the Bios, CPU-Z (or probe software) and a voltMetre reading is can all be different unfortunately. Not sure if your ASUS M/B has the 'Over Volt the CPU option', have a look for it and make sure it not set. (My A8N32-Sli has it and I think it will zap another .2v, so 1.35 is infact 1.55v if I'm reading the manual correctly!)

At 2.65GHz:



At stock:



I'll fit the new mobo and HSF tomorrow and see what happens.

Update: Fitted the AC 64 Pro and temps at idle are around 50ºC according to Everest... but then that Core Temp program reads the cores at 33 and 42... I don't get it.

[manwithnoname]

I down loaded that 'Core Temp beta' program and get 39C/42C,
Asus AiBooster tells me the CPU is 39C underload. Idle and 27C/23C AiBooster 29C.

I think the CPU has sensors in the cores and the M/B has a sensor near (or under) the CPU.

[NightshadowUK]

Ahhh, well it's gone down to 45ºC on Everest now so I think I'm alright.
