using a spare pc that has ram issues (only 1 out of 4 slots detects).
1gb of ram
1 pci-e 16x, 3 pci-e 1x
sapphire 5970 (scored for $250AUD)
laptop hdd (save some power)
windows 7
gpu's @ 880mhz (stock 725mhz), memory at 505mhz (lowest the msi tool allows).
core temps 59c & 72c stable.
fan speed @ 99% (loud).
averaging 768mH (slushpool)
using diablo with the following options:
java -cp target\libs\*;target\DiabloMiner.jar -Djava.library.path=target\libs\natives\windows com.diablominer.DiabloMiner.DiabloMiner --url http://mem.miner1:XXXXXXX@mining.bitcoin.cz -v 2 -w 256 FASTLOOP=false AGGRESSION=13
tried cgminer, seemed much slower than diablo for myself.
Ive spent the last week doing some industrious googling etc and managed to find a store that still sells 5970's new for ~$380 AUD, seems plausible to expand this pc to at least 4x5970's perhaps do another 2 pc's.
If anyone has stable old 5970's they want to unload, pm me
