What's the advantage of building a $500 system doing 1600hs and then building 60x of them? That's still $30k. When you can get the same hash with just 2x 4xx/5xx cards or 1x vega and still have more slots to lower the system power overhead? Just spend your $30k on modern, faster, more efficient hardware...
Please show me where you can purchase these cards in bulk at a price that is not astronomical as I would love to fill my empty PCIe slots with them. Some of us are on the path of putting whatever iron on the fire that is making money, even if it isn't exactly the most efficient or latest wiz bang contraption. Even better, when / if (
) GPU prices get back to normal, we have tons of open slots ready to accept them with minimal config and downtime. Until then, they at the minimum, more than cover the expense for electricity of the combined GPU/CPU mining activity and earn back their own cost, slowly but surely, even in the depressed market we are in compared to 3 months ago.-=Slow Growth=-
Someone might see what I did there...
Until then, I snipe cards when and where I can if they are relatively close to what msrp was.
Aha, you are mining IntenceCoin :-)
Regarding filling empty PCIe slots I think these server power supplies does not have PCIe power connectors? So we are limited to cards with power from PCIe slot ony or using external power supplies? I have a Supermicro quad socket Opteron 6276 machine but CPU mining only on that one. I figured out that by using external power supply and powered risers it may be possible using GPUs too but right now I have a separate GPU mining rig.
Some servers do have PCIe slots and VGA power cables. My Supermicro server is a dual 6348 Opteron that has dual 1200 watt power supplies and has 6 PCIe slots and four 6-pin VGA power cables.
Expansion Slots
Three (3) PCI-Express x16 Gen. 2
One (1) PCI-Express x8 Gen. 2
Two (2) PCI-Express x4 (in x8 slot) Gen. 2
I currently have three Nvidia GTX 750 in the three PCI-Express x16 Gen. 2 slots.
