Hi,

I just got this ASROCK motherboard after 1 month of wait as it was on backorder was very excited as i had read good things about it, but it is failing me.

ASROCK H81 Pro BTC motherboard
4 X sapphire TRI-X
4X unpowered risers ( as the board supplies extra power to MOBO with the molex connectors)
windows 8.1
SSD HD 120GB
4X SAPPHIRES r9 290 tri-x
12GB of ram
intel core i7-4770 CPU


I am losing my mind with this MOBO !

It does not work as advertised !

I can only get 2 cards to work at best ! ... and sometimes even thats screws up

1st PSU#1 (800W) connect to all MOBO connectors including 2X molex and 1 X GPU Directly in 16X slot (no riser)

2nd GPU on 1050W PSU#2 (unpowered 1x to 16x riser in 1x slot closest to CPU) works sometimes but mostly not recognized or has exclamation mark

3rd GPU on PSU#2, when by miracle windows recognises the 2nd GPU and I can hash with both I try and add third (tried in all other available 1X slots with 1X to 16 X unpowered riser. It wont boot up or I get the windows system recovery crap.

Someone please help I have been at it for 3 days and I am losing my mind!!!
