RE: Mine more ETHereum with RX470/RX480 Bios Mods
I confirm you number on my RX480
I discovered TBP at 100W which allowed me to consume 20W less (I changed too Max Power at 100W).
Striges 1650, GPU at 1100MHz, Mem at 2100 gives 29MH/s on one card, while the other refuse to go above 2000MHz VRAM... maybe there is more a problem with the PCIE16x slot (not yet using a riser, waiting for delivery).
I have PCI errors.
I had good result with RX470 MSI above 27MH/s without TBP tweak, but it died of electric problem (is it related?)
I have been seeing the same. But found anything higher than 28mhs to be unstable, over long period of time. even MSI afterburn overclock at 2100 and 1150
Yeah I've backed-off some OC's as I would rather the rigs were mining 100% of the possible time than faster but less reliable.
