i use 6 cards in dual mining mode and have a setup from 1000mhz and 900mvolt --> power @wall 1000 Watt with 26 per card and 155 MHs over all 6 cards
if i go down at 800mvolt the system will crash. i try tomorrow 850mvolt to save some power

is is better and more save if you connect the Molex Power cabels on your asrock mainboard, so you have more power on the pci-e bus and the normal mainboard power connector is not so under load / reduce the heat from the main connector --> very importend!

Are you mining at the moment of taking this screenshot? If so, stop and then open Wattman... You can click on those N/A fields and you can adjust value... All my 480s are at 1000mhz and 800 m, pulling ~ 140W each @ 24.5MH/s Am am using Newest ATI Drivers 16.7.3 on Win 8.1 Ah, yeah i was mining. Now i got it to work. Thanks. is is better and more save if you connect the Molex Power cabels on your asrock mainboard, so you have more power on the pci-e bus and the normal mainboard power connector is not so under load / reduce the heat from the main connector --> very importend! I never use the molex connectors when using powered risers. People have been burning stuff that way doing that on this mobo. This is the third time i reuse these systems and never burned anything during the last 3-4 years.

Something fishy is going on here.
GPU-Z is reporting a powerdraw at around 110w on every card. But my watt meter at the wall is reporting 1255w for the whole rig @ stock clocks.
110x6=660w My system cant pull 595w, more likely around 70w..
Maybe my watt meter is broken, it have to be ?

This is the third time i reuse these systems and never burned anything during the last 3-4 years. What you are saying is true, but only for one who is using USB Risers, since they have no 12V lanes connected to the PCI connector on the card... If you were using ribbon risers then connecting 2 molexes to the MB would be a good thing to do... With USB Risers those are not used at all... On the other hand you have to connect power to the risers via Molex/SATA connector. All the best

On the new H97 Anniversary ASRock Boards, if you have 3+ cards it wont boot unless you plug in the molex on the board. At least that was my experience, even with USB PCI-e risers.

I confirm that, I have a H97 Anniversary and mobo doesn't boot if you don't connect the molex on the board. I'm using it with 5 cards.

GPU-Z appears to only look at power draw via the PCI-E power connector(s) on the cards - which leaves out 60-80 watts drawn via the actual PCI-E SLOT by each card.

There are already numerous information about the GPU mining. You can search the mining section.

i like this build, asrock h81 pro btc or equivalent, like the h97 annyversary or the pro-g 8 giga ram g.skill sniper 1866, verycheap memory, ssd 120gb sandisk plus also very cheap, g1840 for the cpu and r1000i, but this is good only for 6 or 8 pin gpu, not dual 6+8 gpu

Is it just me or the whole "mobo died in 2 hours" was a mountain out of a molehill?

I confirm that, I have a H97 Anniversary and mobo doesn't boot if you don't connect the molex on the board. I'm using it with 5 cards. At the end my mobo is fried. This morning I checked it because I couldn't connect via SSH ... and... The problem is like roitpls said, if you don't connect the molex in the H97 Anniversary, the mobo don't startup... Now I'm thinking buy a H81 Pro BTC, if the mobo let's the user connect the cards without connect the molex... Well, now waiting for a new mobo

Well, now waiting for a new mobo I run H81 mobos in all my rigs and have done it for years. I have never used the molex connectors because i have always used good quality powered USB risers.

Ok, I know it, and I readed a lot of information about not connect the molex to the mobo, ... but the problem with H97 Anniversary is that the mobo doesn't boot with +3 gpus if you don't connect the molex.. a message is displayed, and it's impossible boot. Ok, then I will buy a H81 Pro btc. I expect the memory and cpu are ok!. 1st lesson!

The cpu and memory should hopefully be ok, i have burned other kind of mobos in the past without killing something else.
