Hi guys! Great forum, it has helped me a lot in the past, I hope you can help me now; I am pretty sure you will.

I built a Render node like this:

AMDFX8350, stock, CM Hyper TX3 EVO
ASUS M5A78L-M/USB
2x8GB DDR3 1866
SSD Sandisk 64GB

I want to use it just for render as a slave on a small renderfarm. After some test, i realized it was going slower than it was suposed to be, so had a look at temperatures, voltages, etc (I don't know much about this so please help me)

I noticed the core multiplier dropped from x20 to x7 on full load when CPU temp (TMPIN0 in CPUID HWmonitor) hit about 60ºC, and it has crashed sometimes at this temperature.

I took a look at voltages as I have told you and i dont like +12V to be at 8.2V, or -5V to be at -9.216V, but I really dont know what these means.

I have read some posts about this issue but can´t solve the problem yet, so I ask for your help. I will really apreciate it, Any idea? Thank you all!

I upload idle and full load HW reads.

Solution
8.2v on the 12v rail is baddd, I don't like that at all, but HW is known to give some bogus ass reading too though....get a multimeter and probe the rail and see what you get

Hi Jook-D and thanks. PSU is a 500W bundled included in a B-Move Matx tower (B-Move Chill MicroATX 500W) Maybe I went cheaper than the setup needs to work properly...

Thanks JR1988, but I don´t have such a meter and no idea where to measure xD! I also tried speedFan and values were much closer to they should be... So maybe voltages are ok but core multiplier drops from time to time when full load...

Shall I have a better MB? No idea, I´m lost...

I have read that when a temp is so stupidly high is due to my mb doesnt have such sensor and the software make it up. I thnik fans work propely, i have the case opened and everything is ok, or is what it looks... Cpu heatsink is not as warm as HW is telling...

I dont have multimeter but will get one... Meanwhile, any more ideas? Thanks!
