Different RX 5700 XT cards crash on OC/UV

[rashid.sharafat]

Hello everyone
I am a new miner. I have total 4 cards, mentioned below.

1. [XFX RX 5700 Triple Dissipation 8GB GDDR6 3xDP HDMI Graphics Card RX-57XL83LD8 5700 XT RX-57XT83LD8] - 2 qty.
2. XFX Thicc Boost Up Graphics Card 5700 XT RX-57XT8TBD8 - 2 qty.

Right now, I am running 2 cards “Type-1: Triple dissipation” only, with the following OC/UV settings:

GPU 0:
Radeon RX 5700 XT 8176 MB · XFX
Micron GDDR6 · 113-180W2NAVI10XT8GD6_MS_191122_W8
52.02 MH 62°/90° 35% 133 W 1400 780 900

GPU 1:
Radeon RX 5700 XT 8176 MB · XFX
Micron GDDR6 · 113-180W2NAVI10XT8GD6_MS_191122_W8
52.05 MH 57°/96° 35% 132 W 1400 780 900

Type-2 is not connected, so no details are available. Everything is default, nothing changed for both type-1 and type-2.

When I connect the Thicc III ultra card, and adjust some OC/UV, mining gets crash.

Please share if anybody running his/her mining with these 2 cards and has the correct optimized OC/UV settings.

Running 5.4.80-hiveos.

Looking forward to your responses.

Thanks in advance.

Hi, please, please PLEASE bring the memory temps down if you don’t want to brick your GPUs.
Use AutoFan or manually run the fans on 60-80%. Fans are cheap. GPUs aren’t.
Try 1400 / 770/770/1350 and memory between 910 - 950. Test the memory until it crashes by +/- 10.
Get your VBIOS moded. After you do that you can see 57-58Mh at 100w.
