First of all, I would to thank you all for this wonderful community where a lot of interesting information can be found.
I don't want to seem desperate, but I kind of am. Despite all the information on the site, I’m stuck and I really need your help on my first rig.
After battling a week to run my rig (I had a defective motherboard AND a defective RAM from Amazon) I finally got it working.My configuration:
- 4 off ASUS - ROG-STRIX-RX570-O4G-GAMING,
- MSI Z270 A Pro,
- RAM 4GB Corsair - CMK4GX4M1A2400C14,
- EVGA - SuperNOVA 750 G2,
- Windows 10 / Claymore Dual Miner.
- Latest AMD driver from this month
Until today, my rig was running with 2 RX 570 mounted on the motherboard because I had no risers. Everything was running perfectly fine with both GPU overclocked at 27mh/s.
Today, I received 4 USB risers that I ordered from Amazon. I plugged all the 4 GPUs on the usb risers and configured the bios so that the GPUs would be detected (at first I had a code 12 error, but I solved it thanks to the instructions here : 6 GPUs on windows 10 problem
, New 6-GPUs Mining Rig issues
).Here comes the problem:
When running Claymore Dual Miner, all the 4 GPUs start with their maximum hashrates but then rapidly drop to 4-2 hashrates. Sometimes, one of them jumps to its maximum hashrates (27-26) but then drops again. overall I have a very unstable hashrates with an average hash rates around 10 mh/s (after 1Hour).
At first I thought it was a power supply problem. So I tried with only one GPU and the problem was still there.
Then I realized that the computer was very slow, so I checked the CPU and memory usage. There I saw that when Claymore Dualminer was running, the CPU usage was at 100%, which it shouldn’t be (see below screenshot)
(sorry for the omelette du fromage
Do you have any idea of what is wrong in my case?
Thank you all in advance for your help.
