Title: Problems with 3 GPUs Post by: superness on April 20, 2013, 11:38:46 PM Would have loved to drop this in a more appropriate forum.. but here we go
I've been mining over the past week with 2x7950s, and while I was doing that I ordered two more 7950s. Here's the problem: After adding a third 7950 to the system my computer boots and runs incredibly slow. ( Boot times went from ~15s to multiple minutes ) Now, I seem to be able to mine just fine once it finally starts up but it's mostly unusable. Any one experience anything like that? Any suggestions? My PCI-E slots are 16x16x1, my PSU is 1300w, the CPU is beefy, there is 6gb of ram in the system.

And I'll say that I have tried every combination of two of the three cards and it runs great, while adding a third card runs very poorly.

If anyone else has an ASUS P6T mobo and has this issue, save yourself time/headache and flash your bios! Title: Re: Problems with 3 GPUs Post by: ZeikHunter on April 21, 2013, 06:09:18 AM I've got this same problem, but my topic got deleted.
mined with a 5970 for a few weeks, remembered I had a 5850! added that in the mix, now no matter what options I specify, cgminer stops @ "Started cgminer 2.11.4". Ends up chewing all my ram until I BSOD 1kw psu, amd 6-core proc, 16gb ram, on win7 64 |
