The HiveOS power value is very inaccurate. I found up to 40W difference between actual power used by the system and the HiveOS. You can’t tune the rig with these numbers.
Try Red Team miner to try to reduce the power. Again, get a wall power meter if you want to tune your rig.
so i belive you drive bedder with only make the 1500MHz/1550MHz mem Straps Kopie/Paste … i have my test card now at 58MH/s but if you look on my screenshot the card with the bigger hash number hase the lowest share rate of all other … and the other cards only have the mem straps kopie paste …
I made some tests by myself with tREF value. I think it does not affect hashrate…I think it affects wattage and memory temps. I raised mine to 32000 and I saved about 3w and 2 degrees per card (that seems too big for tolerance). So I would answer b and c for the question “what´s higher tref value for?”
Tomorrow I think I test 64000 and check what happens…hiveos does not show any wattage difference…but it shows less memory temps of course. my rig actually is 0,402 mhash per watt out of the wall…think that´s ok for 2 x amd 5700 cards
I followed this guide and have the exact same GPU. I did not adjust my tREF number and left it as stock.
All I did was modify the timing straps and tune in Hive.
my cards run with ± 55 mhash at 1330 core and 890 mem clock. I didnt push them to highest mhash, I choosed sweetspot for efficiency…I didnt want to waste 40 w per card for just 3 mhash gain…
Do you have any RX 5600s? I’m debating buying 6 (RX 5600 XT Thicc II PRO) - they’re on for a decent price. But I’m torn between waiting for supply for more RX 5700s
I just added 2 new 5700 cards and wanted to show the difference between stock bios and modded bios…overclocking settings are equal, just bios settings are different:
Yes, I tried two different mods. First with only the memory timings updated and the second with the 5700 Non XT bios and tRef settings as listed in the OP.
