Title: 4x 6870 Windows 7 Miner Crash Post by: Reno on June 24, 2011, 10:49:29 PM Hi there,
got some issues with my new Rig. Got 4x 6870 running on Windows 7 64 bit. I can mine with 3 cards without any problems, as soon as i plug in the dummy plug for the 4th card the miner won't start anymore, just crashes instant (tried: Phoenix Miner, Phoenix Rising, GUIMiner). Got a 1200w high quality PSU (Silverstone) with a lot of ampere etc. Mainboard is a MSI 890FXA-GD70. I tried to connect 2 cards with a crossfire cable and put the dummy plugs into the 2 other cards. This is working, but i can't adjust the core clocks, memory etc. and the crossfire mining performance is about 15% lower. I remember some older thread with the same problem but i can't manage to find it anymore :( MSI Afterburner won't start either "Unable to initialize display driver wrapper". Any suggestions? I can switch to a linux distribution too if this will help. Edit: Tried 11.6 and 11.5 both with sdk 2.4 Title: Re: 4x 6870 Windows 7 Miner Crash Post by: padrino on June 25, 2011, 01:02:22 AM I had 6 GPUs working in Windows 7 with 11.6, couldn't get it working with anything but that but when it was MSI afterburner couldn't hang. I moved to Linux and I can run 8 stable, I gave up fighting Windows.
