My servers are too old. 2U servers or 1 U servers. All PCI, but I managed to find PCI - PCI-E 16 extensions and purchase some HD 5770. In fact two for each server, waiting for the parts to be delivered. I heard of Linux Coin, is it easy to use? Will it recognize the HD 5770 etc?
I moved from linuxcoin to BAMT recently, and the uptime is much better. If the miner locks up, it restarts it and reconnects. Also, the multiple rig monitoring with "mgpumon" over ssh is pretty awesome.
