Hi Igotek, pls do you have Nitro or Pulse? I have Pulse and even if is clock and memory setup lower, my temperatures are very high 1400/930 = 96C. The temperature in room is around 20C.
Hi everyone! I also have Nitro+, all Sapphire rx5700xt.
and one Special Edition (the one with the stock RGB fans)
Some of them are with Samsung memory, and some of them are with Micron memory. I see the samsung mem is more efficient, but not stable on high mem 900 or higher.
Micron I was abel to push arround 940/950. In some cases also to 960.
The highest hash rate on Samsung was arround 55,6-56,4 MHs.
The highest hash rate on Micron was 58,7-60,13 But memory temp getting high, so I do not uses it with mem940 or higher.
First I also thought Samsung memory might be better, but it seems not to be.
Unfortunetly when you buy a card you can’t choose the memory type 
Did someone found better settings for this card?
Hereby I share some screen shots.
Happy mining!

Also looking for this. I just extracted my original bios and did a basic mod to this but I’d love a better one. I just copied the 1550 strap to the higher ones
Hello,
I have gigabyte cards. I tried many setup and for me this is the most efficient. I use the same settings and same bios for each cards, but I’m not able to reduce the consumption.
What’s wrong with my settings?
Thank you in advance!
Hi did you change the tRef=6000 that can give you arround 0,8-1MHs extra.
Hi,
I’ve setted the tRef to 9000.
I am also trying to make changes. The total RiG needed 990 W. 353MHs
Now I try to lower it with this settings, try is:
CORE:1430, DPM:7, VDD:760, VDDCl:770, MVDD:1300, MEM:940, PL:110
Now the total RiG needs 920 W. 352,7MHs
On the 6 cards I have lost only 0,3MHs but lower Watt. NOT Stabel yet but I am working on it…
What is that “DPM:7” and “PL:110”? How you set them up and what are they exactly?
PL:
Power Limit sets in Watts and allows you to limit the power used by the core graphics card. In most cases, AMD cards are not required if the frequency and core voltage are set. Currently applicable only to Vega and Navi GPUs famil
DPM:
This is required when undervolting. You should use this parameter with ‘Core Clock’ and ‘Core Voltage’.
DPM (Dynamic Power Management) or ‘Power Level’ of GPU core. For RX cards it’s a value from 1 to 7 . Default is 5 . Lower the value to downvolt.

thank you! 
Szivesen! Welcome!
Szia!
Köszi a segítséget / thx for your help! 
I tried with tRef settings from stock value to 64000 which is almost max possible. I didnt recognize any change in mhash. 6000/ 9000 seems to be a good value. Actually I´m at 16000 because I´m too lazy to go back to 9000, no measurable difference at all for my cards.
Hi, how did you managed to fill in so high value? I cannot fill in more than 9000.
