I've been mining Argon2d algo with my RTX 2060 rig (they actually do pretty amazing, up to 350kh/s@110W - small OC as im not a pro in this field
Recently, I've bought RX 5700. They have 8gb GDDR6 memory and 256 width bus so i thought they will do at least 30% better on argon and will give me around 480-500 kh/s.
Apparently i missunderstood something as the card is doing barely 370@200W. It is weird as on ETH i get 55mh with no OC. with rtx, being fully OCed i get only 32mh.
Using afterburner let me put memory clocks at +100 (1860MHz) where on rtx i did +950. I use windows becasue im not that techy and HiveOS had rtx fan issue and my cards were getting hot up to 90C
So i have felling that there is some difference in GPU built that influence hashrate on argon2d. Cant find any information on that regarding to rx 5700 and im not that wise in field of computer/gpu hardware. Generaly i want to unlock the memory and put the clocks as high as possible.
I've found more power tool that allows unlocking RX cards clocks. Already saved raw BIOS via Saphire TriXX.
here is what ive found on igor's forum:
Mentionable memory OC with AMD cards is nearly impossible. DPM stands for Dynamic Power Management, not for a final max clock rate in a slider. The memory OC goes over Wattman, but it is unstable as hell with no headroom. The reason why is also the kind of power delivery to the memory controller. It goes over MVDD and VDDCI and it is going wrong, if the balance between both is not perfect.

I should be able to put in max mem field: 1750? (14,000 / 2 = 7,000 / 2 = 1,750?). didnt touch that to not damage the card.
generaly of speaking im wondering if those 370kh/s is the limit for this card on argon2d? RX 580 8gb does around 200kh/s..yet in wodners me that rtx with 6gb gddr6 does 360@100w and rx with 8 does the same with more power.
thanks in advance
