Again i am facing some bottle necks.
One i have already in mind, that windows supports only 4 GPU. Thats why using latest catalyst drivers. If windows don't support more than 4 & if not 8 GPU, then have to try Linuxcoin. Linux & programming will take some time for me to understand which will make 2-3 days rig not mining.
But i will try to keep it very less. Already going through linux.
2nd bottle neck, i faced yesterday which is unexpected.
Mother board is MSI Big Bang Marshal with 8 pcie slot.
I thought connecting card with 16x extender in pcie_1 & using 1x-16x extender connect other 7 cards.
But it seems not all pcie slot works with 1x-16x extender. It seems works in alternative slot.
Pcie_1, pcie_3, pcie_5, pcie_7 with 16x extender cable &
pcie_2, pcie_4, pcie_6, pcie_8 with 1x-16x extender cable.
I bought 21 1x-16x extender cable & 2 16x extender cable from Cablesaurus.
Now i connected 1st card with 16x, 2nd with 1x-16x & tried 3rd with 1x-16x & failed.
Only 1st & 2nd card detected.
Tried with spare 16x cable & 3rd card detected.
Anyone came across this problem?
Also, now again going to order 6 nos. of 16x extender cable from Cablesaurus.
I hope to run 16 cards with total mining capacity 6.4 Ghash/s soon. Trying all humanly possible things i can do.
