Topic: Sapphire Nitro Rx470 4GB very low hash rate on EThereum (Read 1475 times)
What cable do you use?
Those sapphire have hdmi output and display output.
My trick is use a hdmi to dvi cable adapter.
I plug the hdmi dongle into the sapphire i plug a dvi cable into the dongle and into a dvi monitor this stops the 4mh issue.
Sapphire cards seem to always have black screen no video out issues via the hdmi jack.
I first had this show mining btc with hd 7950 sapphire cards.
Back to rx 470 I have three or four Dvi to hdmi adapter to get past the issues of no video
Which I think causes the 4mh bug
Did you try using the Claymore ethereum miner? Which driver are you using? It could be happening because of undervolting... I'd suggest you to first try re-installing the drivers and do not play any over-clocking with it. If even that doesn't work, try a re-install of Windows 10.
USB risers are usually fine, I don't think so that it is their problem until and unless it's a 3rd class version.

Attach the monitor on gpu2.
try running it without a monitor and clear out all overclock settings.
Hello,
I have buid a second RIG using Asrock Q1900M 4GB RAM on Windows 10 64bit and 2 GPU Sapphire Nitro RX470 4GB,
the first GPU is directly connected on PCI-e x16 and the second one with a powered riser X1 flat cable.
The directly connected PCI-e x16 GPU work at 25 MH/s but the second one run at 4 MH/s does anyome have the same issue ?
Can be a rider PCI-e card problem (i have try 2 different riser with flat powered cable?
I have try all possible combination on Bios side (gen1 gen2 gen3).
