Hi, am inspired how you're able to use old HP workstation doing this. I was trying on old HP workstations but fail to get more than 3x GTX1050ti work (75w each). PCIE 1to3 or 1to4 expansion cards won't work either on both motherboard pcie slots.

I have tried slotting GTX1050ti into PCIE Slot 2 as well primary display (75w draw from motherboard direct) - not able go beyond 3x GPU as well. Actual GPU power draw should be much lower around 63w each.

- HP XW600 (475w) - Motherboard/CPU support: LGA 775
- HP Z200 (325w) - 503397-001 LGA 1156 motherboard

Generally,
- GPU0 in Slot 2 (tried on riser as well)
- GPU1 & 2 powered by PCIE 6P Y split pins + SATA (no split) on each riser

- GPU3 powered by SATA to riser (6P) - SATA should be able to supply 92w to riser ... Not able turn on.

Note: I didn't use Slot 4 PCIE (carries 75w) to connect to PCIE 1to3 expansion card though. Not sure whether the USB cable connected to riser does carry any wattage from motherboard to risercard though without need be powered via SATA/Molex.

Much appreciate your shared experience on this have a few of above workstations to repurpose.

Hi, I am using Biostar TB-BTC Pro (12x GPU) and also TB-BTC 6.0 (6x GPU). Have tried many configurations of hardware setup but could only detect 6x AMD GPU.

I understand that RX OS dagfix only works on AMD GPU and NV OS only on Nvidia GPUs and I should not mix GPUs in single rig.

New to mining and SMOS as well. Am considering to hire someone whom can make my life easier with pre-configured miner configs (no idea how to get it run) - some basic lessons on pools setting/failover pools. as well as some basic lessons/assistance on undervolt/overclock GPU (currently using Power Color Red Devil 8GB RX 580 and Gigabyte GTX 1070 Gaming OC).

Tried to go into the http://chat.miningsimple.net - but couldn't seem log in.

Short of losing more hair over these, am open to consider hiring assistance for the above. Thanks.
