Is that hash rate with the Cryptonight algo? I assume so with such a number of rejected shares.

Claymore Equihash

I'm using a switch box with internetcable. I'm doing another testrun as we speak, 2 hours in and 800 accepted and Rejected 1.
I'm going to do another 12hr test, and check the results, so far its going good.

Unfortunately I don't have any experience with the AMD+Equihash combination. But 800 Accepted vs 1 Rejected share sounds just fine. As already written above less than 1 % rejected shares is fine.

< 1% rejected shares rate is normal. It might not be related to the overclocking. I get a similar rejected (or stale) shares amount if I move otherwise stable rig to the far corner of the house where wifi connection is weak and ping is sometimes too long.

6000 shares and 40+ rejected seems <1% shares are rejected, commonly that's acceptable.
For better result, you should check OC set, internet connection and power supply status.

Windows 10 PRO 64 bit with 17.10.1 Crimson AMD drivers and Sapphire trixx.

- Intel Pentium CPU G4400 @ 3.3GHz
- 2 x 4 GB DDR4 Crucial
- GA-H110-D3A
- 1000w 80+
- 6 x RX570 Red Dragons (elpida)

Last night did a testrun, i got 6000 shares and 40+ rejected shares, to much OC?

Sapphire Trixx settings :

Coreclock = 1325
Memoryclock = 2000
Powerlimit = -15%
GPU Voltage = -120V

Getting around 1870 - 1880 h/s with 875w at the wall. But with those many rejected, i think i should reduce my OC?
Is -120V undervoltage to much for the cards ?

Tips & ideas ?
