Hi guys, been lurking a while thought id bite the bullet and join. I have been mining since November 2017 - so still new to the game.
I have 2 mining rigs 1 is 4x 1080TI (was gaming Rig - was going to expand but prices gone mad!) and 2nd rig is 5x Asus 570 Expeditions OC 4gb + 2 x Nvidia 1080.
For now im just using nicehash to Mine.
Problem i have is 2 of the Asus 570's seem to be locked to default bios/clocks.
2 of the other 3 i have used annoraks OC custom rom and now get 29MH for about 95W
1 Card i have used the 1 click bios (think the trimmings are too tight for the OC rom) and get 28MH
But the other 2 cards, no matter how little a change 1MHz in Mem frequency or 1 Mhz in GOU frequency in Bios the card fails in the miner i get a driver stuck in thread then BSOD.
Also Card 0 which is running at 28MH in the miner application (claymore 10.8 i believe? using Nicehash legacy 1.8.
it shows as 28MH but it will then drop to 5MH or 6MH and will also drop speed on the 2nd algo from 850 down to 150. I have tried with stock rom, modded rom, no OC but the result is the same - is that a problem with the card or is the mining software reporting the rate wrong? Just concerned over a minute it does it maybe 10-15 times? over the course of the day that's a decent drop in speed! - I have already swapped out riser and cables.
Currently all the AMD cards give a combined rate when duel mining eth & decred of 130 which is ok but knowing that it could be 145-150 is bugging me!
In GPU-z every single card shows the same memory same version same everything there is no difference shown at all - checked line for line.
Any help appreciated - have posted on many forums with no luck
Thanks in advance
