ok .. the bios of this asrock btc has no such option... its already for mining produced.

Does anyone has a solution/suggestion what i can do now?

Ok i did that troubleshooting...
Windows is updated
17.5.2 Drivers installed
in bios settings i cant find 4G Decoding but pcie is set to gen1

if i start claymore again he instantly shutsdown after DAG Buffer set .. (it goes so fast i cant tell exactly when)

i tried genoil-zec-miner and this works ... BUT

i also tried nicehash miner and this shuts down somewhere in the "gpu benchmark" ...

any further solutions/opinions?

thanks for the fast answers.

system swap is @ 16 GB

Bios-settings and the rest of that troubleshooting will be tested as soon as possible.

Hi,

here is my configuration:

ASRock H81 PRO BTC R2.0
2x 4GB Crucial DDR3L-1600
Intel Celeron G1840
120 GB SSD
6x Sapphire RX 580 Nitro+ Special Edition connected with powered Risercards
Chieftec Navitas GPM-1250C 1250W Netzteil

Win10 Pro 64bit

Everytime i start Claymore-Miner it freezez the Computer after DAG-Buffer.
I tried different drivers, some BIOS-Mod but i cant get it to run...
Also tried just with one and the same it freezez ...

It also does with all graphiccards are set in normal mode (without bios mod)

Can u help me?
