Title: Crashes at random intervals-1x7950 1x-7870xt Post by: ccplz on May 31, 2013, 09:10:13 PM Hello,I'm facing difficulties mining with my rig.
Once I start mining,everything will go smooth,for an hour or so,sometimes longer or shorter,it's really random,then bam,black screen and hard reset. GPU:1x7950(gigabyte) 1x-7870xt(sapphire) both relatively new(Running at 19 intensity,24000 thread concurrency at 77/69 degrees.) PSU:Corsair TX850W v1,new as well. CPU:Intel i5-2500 RAM:8gb DDR3 ram. Mobo:Gigabyte GA-P67-DS3-B3 I've tried everything these past days,from removing and reconnecting every cable,to switching the cards to another PCI-E port. What I ask of you is,can you pinpoint the piece of hardware that is causing the problem? Please note that the rig used to work normally 2 weeks ago. At this point I'm considering buying a new motherboard,is there any chance that it's the one malfunctioning? Thanks in advance.

So I decided not to mine tonight,and I figured out that the pc will still reset randomly,even when under 0 load.Any ideas? Title: Re: Crashes at random intervals-1x7950 1x-7870xt Post by: Slave2school on June 01, 2013, 09:44:56 PM Sounds like bad ram or psu. Try memtest86.
Title: Re: Crashes at random intervals-1x7950 1x-7870xt Post by: jdebunt on June 02, 2013, 05:48:24 PM i've had an issue like this on an old computer of mine (well, not old, one of the previous comps) :)
It used to run fine on max level, then blue screen & hard resetted. It was , as Slave2school mentioned, a RAM issue. I had to go into the BIOS & downclock the ram, because else it'ld overheat pretty fast. I ended up replacing the ram & everything worked fine for 4 years :) do a memtest & see what it tells you :) or try downgrading the ram speed in the bios.

I have a similar problem with one of my rigs. Although I didn't run memtest, I did run the built in Windows Memory Diagnostic tool (Control Panel -> Administrative Tool -> Memory Diagnostic). This test essentially froze. I swapped out the memory and now I'm hashing away. The BSOD would happen pretty quickly before. In the past, I've also had random BSOD and crashes due to a bad HDD that even passed HDD checking tools like spinrite! Best of luck!

This was with some "fancy" Ripjaws ram and a gigabyte 990fx board.

Now that I disconnected it,it has been working fine for 6 hours+ Title: Re: Crashes at random intervals-1x7950 1x-7870xt Post by: rtgornik on June 03, 2013, 02:42:36 PM Thanks for all the posts,I tried unhooking every piece of hardware I didn't need and apparently the one causing the restarts was the dvd drive. Now that I disconnected it,it has been working fine for 6 hours+ Very interesting. Just goes to show you, try EVERYTHING and try it one at a time. I'm glad you seem to have found the solution! |
