ASUS RX 6600 XT 32.16MH/s & MSI RX 6600 XT Only 28.76MH/s - Total 60.93 MH/s with 106 W

I have a issue with MSI RX 6600 XT that only give less than 30 MH/s ( Only 28.76 MH/s ). I really appreciate help for setup better settings.

reduce the core clock to 865 on the MSI and Memory . not always higher is better.

I try lower the memeory and the card crash. Some specific setting

I have 4 assorted RX 6600 XT’s, including the same card as you. It’s doing 32.11 MH/s @ 59W
I use these overclocks: 1100/600/1155
My XFX and ASUS cards don’t always like the memory clock at 1155, I have them at 1125.

These are the settings for all my cards. Except 1 ASUS Dual 6600XT, I have the memory clock at 1125. It doesn’t like much higher than that, the miner starts showing it “dead”.

Something is screwy, cause your ASUS card is mining about the same MH as mine. Mine is at 31.94MH/s.

I have a lot of these cards.

Please review my settings below. Rock solid for the last 1 month.


I have the MSI 6600 XT Mech 2X and my settings are CORE 1350 MEM 1150. I get ~32.5 MH and it’s stable. I changed nothing with Voltage or Fan. Try that out.

Still stuck with the MSI with less than 29 Mh/s

I have MSI GPUs as well. Here are my settings that get me ~32.6 MH/s
Are you using the Gaming X version or the Mech 2X? Mine are Mech 2X.

Hope this helps.

I also noticed that the OS version 0.6-210 halved my MH. I rolled back to the 0.6-209 and everything was back to normal. Just something else to try.

Too high memory clock. Try 1125 1150

When I try lower the memory the MH/s down to 14

After downgrade to 0.6-209@210925 and change to Phoenix @ MSI 28.75 MH/s & ASUS 31.57 MH/s

Try 967 Core and 1135 Mem. I didn’t touch any other settings. I’m getting 32.24 with that.
