Title: Unstable core clocks while dualmining Post by: Kinca on December 14, 2017, 04:43:46 PM Hello guys, I hope you could help me here. I have 8 AMD GPU rig and I am setting dual mining now and trying to find best OC settings for one card after another.
RIG specs: Windows 10 PRO 64 bit Biostar TB250-BTC+ Celeron G3900 DDR4 4GB SSD 120GB Now, I am stuck at ASUS RX 470 4GB GAMING. I have modded BIOS and after overclock, card runs stable on ETH at 28.8 Mh/s. Clocks are core 1150, memory 2000 and voltage 1000. But once I run dual mine with LBRY, clock is jumping 950 to 1300+- and hashrate is unstable about 19 Mh/s. I tried flash back to original BIOS and issue is same. I tried different clocks and voltages and nothing helped so far. Do you have any idea which can cause the issue? Other cards are working good so far. Thank you.

Any ideas what can cause this? Only difference between these cards and other ones which are working ok is that they have just 6 pin instead of 8. Thanks

have you set the virtual mem to 6gb or more for two cards? i will suggest to install blockchain drivers and then try again use claymore commands rather than msi ab claymore inbuilt overclock and undervolt is stable than msi ab |
