Help me max my MH/s?

Good Morning! So I am recently new to mining rvn and so far enjoy it and have high hopes for the price of it going forward so lets help each other stack some coin!!!!

I have done some light reading into mining rvn and here is where im at 24 hours in. Total rewards so far are 30.2 hash as been up and down due to tuning and i do game sometimes lol.. What im mining with is a 6800xt and a 5700xt. Both are gaming cards for original use and purchase luckily at retail cost. Im averaging 62MH/s and topped out at 78 a few times so there som low hashing from the pool. I am using 2miners pool and their software suggestions. I have solar so electricity cost isnt of main concern cuz even if i ran them at theoritical max at 750 watts combined my increase would be about 15 bucks.

So heres a break down of each card

MSI Mech OC 5700xt had since july 2020. Running @ 1520MHz@ 925 mV 1800 on vram and 0 on power curve, it is running @ 160 watts 68c and about 26MH/s on teamredminer.

ASRock Taichi 6800xt had since December…Gotta watch those drops but havent been lucky again since lol. Running @ 1800MHz @ 1010mV 2100 on vram using around 200 watts. getting about 32MH/s average.

​

Just curious if anyone has a similar setup and or advice..again my goal is acumiliation of coin not profit over power.

Also i think im a raven coin fan for life lol love the logo!!
