Settings RX6800XT for mining TON

[Atlas007]

Hello everybody share settings for mining TON on video cards RX6800XT

I have the following data points from limited testing with Lolminer:

6800XT Sapphire Pulse
core 2000, mem 0, vdd 800, hash 3722, power 158
core 1900, mem 0, vdd 750, hash 3563, power 126
core 1800, mem 0, vdd 730, hash 3352, power 113

6800 Asus TUF
core 1800, mem 0, vdd 730, hash 2831, power 117

6700XT Sapphire Pulse
core 2000, mem 0, vdd 800~820, hash 2000, power 86

Memory is not used at all by the SHA256-TON algo, so I set it to 0 and it defaults to the minimum 1000mhz.
I am curious to try SoC VDD settings as this made a big difference to 6800 power consumption on ETHASH.

You should set the memory and voltages, i did for my 6700xt and reduced 10W and 4°c

Thanks, that’s a great idea.
I set memclk = 1000, VDDCI =700, MVDD = 1200, and it dropped 8W off each card. I really needed this extra headroom.

Great, but that’s too much voltage for 1000mhz i can go as low as 400mv on memory

Room temp 35°c

A few of my cards really don’t like MVDD below 1200 - they crash HiveOS.
