Managed to put 6 RX 480 on a mobo using Corsair RM1000i 1000W. Running fine for an hour or so. Will update if my rig shuts down.
P/S: Did not test it with watt meter Setting: Stock Memory, GPU & Power, 60~80 Temperature, 2000~4000 Fan Speed Rig: Intel Celeron, 8GB RAM, 1TB HDD, MSI Z87-GD65
you don't need a wattmeter actually, just install corsair link, will show the wattage in and out

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

you don't need a wattmeter actually, just install corsair link, will show the wattage in and out I have the 1200W power supply. The efficency displayed is always 93%. I am quite suspicious about the reading.

My undervolt 6x R9 390 draws 1030W from the wall and hash at 165 MH/s. I use the 1200W Corsair platinum.

Can someone measure how much ampere RX480 is using from sata-molex cable from USB power riser? I measure how much xfx 280x is using, so we have some information to start from Post screen/windows - not doing anything ( 0.29A x 12V = 3.48W + 0.61A x 5V = 3.05W = 6.53W total from riser ) <- YELLOW 12V wire <- RED 5V wire Mining ETH 950/1250@1.074V ( 1.88A x 12V = 22.56W + 0.87A x 5V = 4.35W = 26.91W total from riser ) <- YELLOW 12V wire <- RED 5V wire1000/1500@1.068V ( 2.26A x 12V = 27.12W + 0.87A x 5V = 4.35W = 31.47W total from riser ) <- YELLOW 12V wire ( RED 5V wire -> same as on up photo ~ 0.87A) <- 950/1250 - GPUZ - 1000/1500 -> So my conclusion is that gpu draw power from 6pin or 8pin ... etc, memory draw power from pci-e slot

I know the R7 370 also uses alot from the slots, around 50Watts last time I measured. Much much more then any 7970/280x I had tested.

For the mining, it is better not to use water blocks. There is no point of running your miner at higher voltage and inefficiently.

The problem is , AMD is good only on eth , but in another script not run .
This is only one example with new siacoin :
Siacoin Go Pool miner hashrate: – GTX 1080 – 1945 MHS – GTX 1070 – 1466 MHS – GTX 980 Ti – 1220 MHS – GTX 970 – 803 MHS – GTX 950 – 385 MHS – GTX 750 Ti – 301 MHS – RX 480 – 872 MHS – R9 280X – 849 MHS – R9 290x – 1116 MHS
In my country the board cost 300€ for 8gb , its more expensive .

Some lucky miners get their electricity for free and run their cards as hard as they can - so a waterblock can make sense to some

You have two more cards I undervolt it to 1000 mV. When it is running, the voltage will drop to around 984 mV. I also use the 93% efficient power supply. The frequency is about 970 MHz.

I'm running with a Superflower leadex 1200w platinum. The entire system mining Eth (not dual mode) is at 850watts. 2x290x + 2x290 @ 1060mhz 1.039v With dual mining though, each card will consume ~60 watts more and 1200w is cutting it very close for 24/7. Are you running with stilt roms? rops disabled?

Are you running with stilt roms? rops disabled? I think there is no stilt bios for the 390. I have similar set up and you just need to undervolt a lot. The 390 is more efficient than 290. The 290x consumes more than 290.

Just be careful with the PCIE slot +12 V. You need to use the latest AMD driver not to burn the PCIE slot.
