Is anyone here running their Vegas on one 8 pin PCIe cable split into 2 6+2 connectors? I know daisy chaining can be bad but the cables that came with the PSU ( Corsair hx1000 ) are heavy duty compared to other PCIe cables with only one 6+2 connection.
I am running mine at the 2x8pin (technically 8 + 6+2pin) cables that came with my corsairs. don't you have enough of these? with the rm1000x there are 4 of these per psu.
Yeah I have 4x 8pin to 2x6+2pin. Up till now I've only been running 2 Vegas from the PSU using two cables per Vega. Just read a lot of horror stories regarding daisy chaining PCIe cables, although most of this is people using the splitters. I didn't find much info on wether it was safe to use one PCIe cable for each vega
I tried running a 56 off a splitter, seemed to work fine but it was just one. Next I will try two 56s off the same cable. Corsair CX750M. I am mining CryptoNight though, not EthHash, which is very gentle on power compared to EthHash.
I really don't think trying to run two cards that should be pulling roughly 300w from a pcie 8-2 (rated at 150w, and the two PCIE slots at 75w each is going to net you a good result.) I mean i get that the math slightly tracks.. it's just a lot of stress instead of getting 2 psu's or a properly sized one with the right connectors.. for me mining is about uptime availability and consistency. if this is just a lab based test then godspeed.. but i'd be careful
Sorry if I misunderstood your intent
