RX5700XT Randomly crashing (on Multiple brands of cards and MB's)

Hey Guy’s,

The last 4 weeks i have been fighting error after error on my new Rigs.
Got a awesome deal for 72 Brand new cards RX5700 XT different Brands but up till now the only thing they are gathering is dust.

The best i got out of the cards is running stable for 1 / 1,5 days. In this period there is always 1 random card running different from others (litle bit notabele hashrate)

After the 1 to 1,5 day’s of running the rig crashes because a Random GPU Dead message.
at this point the rig isn’t even stable anymore after a reboot it keeps crashing and crashing until i did 3 or 4 hard resets ending up running stable (ish) for the next 1 to 1,5 day’s.

Mine was crashing on phoenix miner every hour and I switched to lolminer 1.14 on HiveOS kerbal 5.6 beta v157 and it ran for 20 hrs.

Do not run on USB sticks, funny things happen, so I switched to SSD runs a lot better.

Running 16GB seems to help a little bit. Your core speed is too low, try 1350 or 1400.

I’m also trying HiveOS stable 5.0.21 kernal v172 with AMD driver 20.30.

I have Asrock H110 and I run PCIE speed on auto and it seems to run more stable than gen1 and gen2.

Disable CSM

Keep a monitor connected to rig or use a fake-hdmi stick
