Title: Dual R9 280X frequent BSOD Post by: Prinzert on January 13, 2014, 02:10:02 PM This rig seems to be experiencing a BSOD on Windows 7 every 4-5 hours.
It does not appear to be overheating in any of the components. It's on a Gigabyte motherboard with a 750W Gold PSU. Does anybody have any specific tips for dual 280x that seemed to be causing BSOD?

if yes it meant ur system not stable much find the sweet spot.it common problem if u too much undervolt it. PSU rating? make sure the power supply is enaff Title: Re: Dual R9 280X frequent BSOD Post by: fattypig on January 13, 2014, 02:44:19 PM This rig seems to be experiencing a BSOD on Windows 7 every 4-5 hours.

Whats your version of cgminer and settings?

They hash at about 700 MH each. They use a lot more electricity than my MSI 7950 TF cards though.

Whats your version of cgminer and settings? I don't have the exact line in front of me. But they're running at 1070 GPU engine ( default ), 1500 Memory Engine ( down from 1600 default ), default volt, auto fan, temp target of 80c ( it hangs around 78 on one and 79 on the other ). I believe I have expire and queue both at 2 ( but I'll confirm when I get home this afternoon ). Intensity is set to 13. No changes to TC. They're both running at 740+KH/s at fans about 40-50%. do u oc and undervolt? if yes it meant ur system not stable much find the sweet spot.it common problem if u too much undervolt it. PSU rating? make sure the power supply is enaff I tried to undervolt but they wont take any voltage changes ( tried afterburner, trixx, asus gpu tweak ). The PSU is 750W Gold...I know it's not a huge PSU but it's plenty to run those 2 cards.

They hash at about 700 MH each. They use a lot more electricity than my MSI 7950 TF cards though. I tried to set TC to 8192 as I saw that used by a lot of people. But, I only get like 300 out of the cards when I do that.

What mainboard/CPU combination are you using? Two GPUs plus a CPU may be taxing the limits of your power supply, depending on how honest the rating is and what the +12v rails can provide. Measure the voltage on your +12v rail while hashing and see if you're suffering from sagging voltage at the cards.

Measure the voltage on your +12v rail while hashing and see if you're suffering from sagging voltage at the cards. It's a GA-F2A88X-UP4 motherboard with an A4 4000 richland CPU. The PSU is a Thermaltake Tough Power. The 12v rail is supposed to be able to deliver 60A. And it's not even running lukewarm. Yesterday I lowered the air evacuation in the room that it's in, and it's actually been running stable for over 24 hours now. Not sure what to make of that. |
