Title: 7950 making computer freeze Post by: Waramp22 on January 04, 2014, 05:42:37 AM I installed a 3rd 7950 TFIII on my mining rig the other day. It ran for a full day and now it is intermittently causing my PC to freeze. Its an MSI 7950 Twin Frozr III. I have noticed in cgminer that the frozen screen sometimes shows very low 5*C for temp or something outrageous like 342*C. Seems like its temp sensor is screwed and intermittently fluctuating is causing the computer to freeze up. Are there any tests i can do on the card? Is the sensor replaceable? Try another driver perhaps?
I have rotated the cards around and this card is the troublemaker.

What's your power supply rated for, and how many PCIE cables does it have? It could be a power problem. If you're running really close, or using crappy molex to PCIE adapters, it may be you just don't have enough juice. I'm running 2x 7950 powered by a Corsair CX 750 W (non-gold,non bronze), and it seems to do just fine, stable for weeks. I used to run only one 7950 on a Corsair CX550, and occasionaly, it would freeze. I don't think that was a great power supply. |
