New to mining - need advice - 5700XT

AMD Cards
1

Hey Guys!

I am new to mining and i want to optimize my mining rig.

I have 3 GPUs:
0… 1x XFX RX 5700 XT
1… 1x Rog Strix RX 5700 XT
2… 1x Sapphire Nitro+ RX 5700 XT

I already flashed Bios on all cards:

→ I copied 1550Mhz VRAM Timings and to higher Mhz like 1800, 2000, 2250.
→ I changed DRAMTiming12 from 2945 to 8835 (because 8835 is 3x 2945)

MY OC look like this:

OC
OC1200×136 40.1 KB

I use HiveOS - Ethermine Pool - TeamRedMiner

The system is stable but not opimal. I am looking for improvements:

  • GPU 0 uses way too much power → 144W
  • I think GPU 2 is a pretty decent gpu so it should be possible to get more than 56MH right?
  • It should be possible to get more MHs on GPU0 and GPU1 or to reduce W right?

In general:

What do i have to do to get optimal OC settings for every card? Is there anything like a guideline?

Thanks Guys!

temps are kinda high too…

What temps should I aim for?

Beside the fans from my GPUs I don’t have any additional fans in my rig. Planning to change that.

GPU2 crashed after 10 hours → i changed MEM to 915

New Test for GPU2:

changed MVDD to 1350 and MEM to 950 → crashed after 5mins
testing now: MVDD 1350 and MEM 945 → stable since 45min

Lets see :slight_smile:

These settings work for me, 5 days now. My hashrate lower than what you have but system is stable and power is reasonable.
