I have been testing two RX 6600XTs since yesterday.

With minimal tweaking (basically only GPU 1350Mhz & MEM 2250MHz, no voltage tweaks) my result so far:

87.5W for ~ 32MHs (total card power on the wall)

More details in this post:

87 watt is too much, things will be easier if you install hiveOS and use popular presets available in the OC tweak settings or lower core Voltage yourself, 55watt is possible on that card

Thanks,

I was testing my 2 pieces in windows and had no way lower voltages yet.
I have several combos (mb+cpu+memory+ssd+psu) lying around which can take two cards so I did not use hiveos yet.

I will try hiveos on these combos (with USB stick). I think even with extra overhead / card (mb+cpu+memory takes about 35W) it makes sense as only investment needed is cards.

It's better not to do mining farms this way.
Then you will redo it all.
It is better to buy a Gigabyte GA-970A-DS3 motherboard or analogs on the same chipset. Although Asroсk or Asus only support 4 video cards, DDR 3 memory and X2 processor are very cheap. If the power supplies are good, then use 2 blocks for 1 mining farm. Sell the rest of the junk.
