Which cables should i get? I saw some have moled power? What is the difference between regular cables.
powered is really only needed for 4 or more cards
what is the reason?
Length also plays a role, the risers 25CM and longer people report that powered cables are required, the shorter type (i guess they are around 10CM) i and other people have had success with.
You need powered risers with 4+ cards because the cards themselves draw power from the motherboard. The 24pin connector can only put so many volts/amps into the motherboard before it blows.
Do the pci 1x cables affect mining speed. It would seem like that would crush memory bandwidth and kill the production rate.Ron
I'm using a 1x to 16x powered adapter (the one in the ebay link above actually) and it doesn't affect speed at all ... in fact it's my fastest card of 3 identical cards by 10kh/s
I'm certainly not an expert on video, but I find that fascinating. I wonder why this process can work in a pcie 1x slot and regular gaming cannot. I would certainly be more willing to consider using risers with less bulky 1x cables than with the 16x full slot cables.Ron
