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?

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

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?

Physics? Ha! This is clearly magic and devilry at work. Prepare firewood! We have witches to burn!
