What motherboard are you using?

I run Windows 8 w/ 13.1 & 2.8

Im running a Lepa G1600 and working on trying to get 5 - 7950s working, up to 4 ATM, on it

Ok good to know, keep me posted when you get 5 or more running stable, I'd like to know about the details.

I honestly think you'd be better off just running 4 cards in one rig, way more stable. Trying to push to the limit is fun but you soon get tired of constantly rebooting your rig etc. I like sleeping well and not worrying if it crashed 3 minutes after I went to bed Grin

Yes it would be more stable, but a simple script to start cgminer when the computer reboots, and a setting in motherboard bios for it to always be on takes care of constant reboots, though I am trying to avoid that all together. And it is extremely more profitable to run x6 cards or more in one rig. The more cards in one rig, the less you spend on infrastructure (mobo,cpu,ram,shell) per card. Which improves the ROI a lot as well.

If I can get 6 stable and it takes me a whole weekend of testing to get it, it'll be worth it. But I don't see your point, it is becoming a huge headache and I've put in(wasted) a lot of time as it is.

Theoretically, GD65 should run 7 cards.

Can you undervolt the memory as well? Maybe it is too hot.

I actually have thought about that, I would imagine the bios has an option to downclock it, which would use less volts if I couldn't force a lower constant voltage. That is if were speaking about the memory for the system and not each cards actual memory, the cards stay plenty cool. The mobo/cpu/ram also stay pretty cool. So I don't think its that, but I suppose its worth trying, have you seen info/post anywhere that recommend this? or confirm any kind of results?
