Hi everyone,

I'm having problem with my workstation. It just freeze after a period. Need to hard reset. I'm not a pro at cpus, but I think it might be the max temp in the bios that is set to low (85C). The bios would let me put it a lot higher, but I want to make sure I don't do anything stupid.

This workstation is used in a renderfarm (my first AMD in the farm... benchmark...) so both cpus are use at 100% all the time for days...

Looked for infos on AMD site on how hight should i let the cpu heat before I risk dammage? Can't found any.

Is anyone know what would be the highest I can go on this setting?

Thanks!

Operating range for Model 8 MP2600+ is 0*C-90*C...

http://www.amd.com/gb-uk/asset...t_ty...ion_Rev_ENG.pdf' ">http://www.amd.com/gb-uk/asset...cification_Rev_ENG.pdf

I would not put the shutdown temp higher...I would put it lower around 70*C

Now this list really pertains to a single cpu setup...but you can go over a few things listed:


Check the following for overheating or perceived overheating:

- Is the heatsink correctly installed ?
--> Verify it is correctly installed.

- Is the heatsink filled with dust and crud ?
--> Clean with compressed air in a can.

- Is the heatsink fan operating ?
--> Replace defective fan with similar or better unit.

- Is the heatsink adequate for that application/CPU ?
--> Verify it meet the requirements for the CPU being used.
--> RETAIL heatsink? May require lapping and better TIM.

- Is thermal interface material used between heatsink and cpu ?
--> Verify it is used, and is applied according to the manufacturers guidelines.
--> Recommended PCM's, thermal pads from "AMD Thermal, Mechanical,and Chassis Cooling Design Guide #23794.PDF.
- Bergquist HF225UT Phase Change
- Chomerics T725 Phase Change
- Honeywell PCM45 Phase Change
- Power Devices Powerfilm Phase Change
- ShinEtsu PCS-TC-11T-13 Phase Change
- Thermagon T-pcm905C Phase Change
--> Recommended thermal interface material aka: grease, gel etc.
- Arctic Ceramique.
- Arctic Alumina.
- Arctic Silver, 3, 5 etc.

- Is the TIM pad cover removed from heatsink before installation, if using supplied TIM pad ?
--> Remove the cover before installation, failure to do so will insulate the cpu from the heatsink.

- Is there adequate airflow or case ventialation ?
--> Verify airflow, add case fans if required.



- Is the Vcore set higher than specified by the manufacturer ?
--> Verify the Vcore is set to the manufacturers specification in the mainboards bios.

- Is the temperature read via the internal temperature diode. Is the tremperature read via the socket thermistor ?
--> Temperatures read at the diode can and will be higher than an external reading.

- Is the temperature sensor properly calibrated ?
--> Several boards have this problem, check manufacturers bios revision history for calibration fix.
--> Does the heatsink feel warm or HOT, if it's warm it could be a miscalibration error.


The other thing is, how old is the mainboard, and are the physical components still in good shape?
