Hi everyone,
I'm currently working on trying to get all 5 GPUs to mine using Ubuntu 11.04 and poclbm, the specs and installed software are as follows:
2x Rosewill CAPSTONE Series CAPSTONE-750
ASRock 970 EXTREME4 (3 x16 PCI-E slots, 2 x1 slots)
AMD Sempron 145
Patriot 4GB RAM
WD 40GB HDD
5x 5870 (mix of XFX and Sapphire)
ATI 11.5 driver
SDK v2.4
bitcoin 0.6.2
pyopencl 0.92 (with python installed)
The mining command: python poclbm.py -v -d 1 ****@gmail.com:****@pit.deepbit.net:8332
With this set up, opencl recognizes only two of the card (chances are b/c I mostly followed this guide:
https://bitcointalksearch.org/topic/ubuntu-1104-natty-64bit-headless-bitcoin-mining-with-ati-115-binary-driver-9239). So I'm wondering what I have to change for it to recognize all 5, perhaps update the ATI driver version? (to 11.6, 11.12, which one works the best?)
Another possibility is that 3/5 cards are on risers, without molex extenders. I know 59** and 69** cards need them, but I was under the impression that 58** did not need them. Anyone know for sure if 5870s will work without molex?
Many thanks!
