Under VRAM Timings, click on memory type and choose MT61K256M32 Micron and copy the (1500 or 1550) strap to the rest of the straps after it, then apply the tREF values as below:
Have you checked consumption at the wall?
The reason I ask is because I was experimenting with my Powercolor red dragons 5700 XT with different BIOSes.
I found that if I loaded the liquid devil bios (A bios intended for a liquid cooled 5700 XT) then the reported wattage in HiveOS decreased but the consumption at the wall remained the same.
I have a theory for this althopugh I have not done any research to confirm it.
I believe that the liquid devil BIOS has a higher power rating than the red dragon and as such, has a different measuring algo to determine the power draw (maybe it uses a different shunt resistor?) so reports the power draw as different from the red dragon.
Anyway, what I am trying to say is that I am not convinced that HiveOS reports the value correctly.
Check with a power meter at the wall.
no unfortunately my mining rig is a bit difficult to check on the wall. I wouldn’t have tested watercooling bios on aircooling tho ^^ in my case i really stick to two card with almost the same definition both sapphire pulse.
my main thing here is that i wasn’t even able to achieve 58MH/s before so even if it’s lying to me on the watt (i don’t think it’s lying more than usual tho) it’s still better in hashrate that what i’m used to see
what exactly do we change when editing the tREF value? I just made a rom for only one of my cards…the only thing I changed was the tREF value. original value was around 2850 for my 1800 Mhz that I run the card…suggested value is 7020, so it´s a big increase. I cant see any difference? Rig consumes 2 Watts less out of the plug…but that´s maybe a measure tolerance? Mhash seems to be exactly the same. So what´s the change when editing this value and what´s it for? mhash, watts, stability with higher clocks? pls explain. thx
i think he ment to put in every tREF value at the associated MHz. I tried this while also copying the 1500 Value under the others + using 5700 BIOS (on a 5700xtx 50th anniversary).
My MH went up from 51 to 55
Thank you!
This is the best post on forum.
1400/750/750/930 settings and your bios is working but sometimes it crashes and dont load all cards and i must HW restart rig 8x Sapphire Radeon Pulse RX 5700 XT.
Do you have experiences with changing MVDD for better temperature ?
hey, what is your Hive OS kernel version you use ?
also what is your other config in hive because in the same settings and micron card i’m on 130W always.
5.6.0-200909-hiveos-beta but i doubt you did what i suggested (bios modding / bios downgrade) because 130 seems really close to what you would get without any modding
