Use this setting “Second GPU” for your OC and it will be ok.

Micron memory is a bit tricky to work with. I have similar card, you can try the settings I used if it works for you.

Geez, I realized just how bad my settings above were…
After many hours of testing, I arrived at this efficient configuration:
Couple of remarks:
AIM: Maintain a high hashrate with as little wattage as humanly possible.
- CORE: I was aiming for 900 MHz originally (anything below 900 crashes), but I couldn’t get that speed to work at low mV value. It would automatically jump to 750mV and stay there, no matter what voltage I set. The nearest speed I found to work, was 920 MHz.
- VDD: step by step, I reached a minimum where it doesn’t crash at 920mhz - 640mV.
- VDDCI: seems to not have any effect beyond a certain minimum. Initially power draw kept dropping, till around 600-ish. I even tried 100mV - no effect. But it did drop a solid 3W from default to 600mV.
- MVDD: Anything below the magical 1300 mV would cause immediate drop in hashrate.
- MEM Speed: The rule “use frequencies that divide by 15” is very true, you can see the difference in hashrate straight away. 1080 MHz is the highest my PowerCollor Hellbound with micron memory will take. 1095 isn’t stable at 920 MHz core.
- SoC Frequency: The minimum I reached safely was 418. I set mine at 420.
- SoC Voltage: The minimum I reached was 755 mV. Anything below would crash. I have it now set to 760 mV.
The result of all this tweaking is amazing - a steady 32 MH @ 49/50W.

You have the exact same chip/memory like my cards. Read my post below, it will help you get much better results.
Thanks everyone for your help. Here is my final settings for now. I been trying for the last 4 hours to keep pushing but efficiency was not there.

What is all your thoughts on the 6600XT is it a good buy around the $500 price point current price?
VDDCI @600 made the difference, I tried your settings and yes, finally power dropped to 50w without loosing much hashrate! very good job thanks for sharing, here you are my settings:
Guys,struggling with registering my wallet. Have windows Tonwallet, and tonpool bot, but how do you actually register your wallet address ?
Nice. But you should be getting better hashrate at 1080 MHz mem speed, try that. Keep in mind, my settings aren’t 100% stable. I did get a restart once over night, so some voltage or frequency might need slight adjustment. I should have a stable config within a week though, we hope. Glad it helped!
Could anybody please help me out with overclock settings for the RX 6600 and RX 6600xts for Flux…

Absolutely correct, at @1080 I can reach 32.44 Mh/s. After some work I found a more stable and efficient oc:
I can probably improve it to 49/50w but I’m happy with 32.75 Mh/s @51w

You should register your wallet here in the telegram bot: @WhalesPoolBot
Then select WhalesPool on Hive Os FlightSheet

My final stable (36+ hrs) config, for comparison:
Compared to your values, I basically exchanged 0.6 MH for 1 watt. I’d say awesome job to both of us
what currency do you mine?
Just setup my first machine (way late to the game) playing around with 1 Radeon RX 6600 XT for now and have several more coming. Was running ETC for 2 days running at 32.73 @ 49W with zero issues. Hope all the rest coming run as nicely.

Very good job. The best I could do with this card is efficency = 0,65 but it depends on the memory, in this case I managed to oc to @1110:
SOC with Micron chipset consumes more watts compared to Samsung while memory clock is lower, they perform about the same but with different settings. As you can see I added DPM = 1, not sure makes a huge difference but I cut down some watts with other cards too
