bought Sapphire pulse RX 580 4GB - bought the BIOS from mining-bios.eu and flashed it.
disabled crossfire, switched to compute and using 18.6.1 drivers with SRB Miner.
than starts with 1100mhz\875mv and 1800mhz\950mv
=all fine but sloooow
than use overdriventool and increase mem clock by 10 - miner does not show more hs or something - i wait 1 minute and increase again and again and again - hashrate the same - after reaching 1950mhz mem clock i deceide to reboot machine, cause i wondering about that the miner didnt show more hs with more mem clock.
After reboot i start the miner and got instantly many compute errors on two cards?! why after the reboot? and why with "only" 1950mhz?
are there so bad memorys out there that cant handle 2000mhz?
EDIT:
one card reaches stable 2000
one stable at 1950
one stable at 1850
that is...bad?! what can i do? throw away the rom from Matthew?!
wrote a ticket...tia
