Hi guys could you help me with my 2 Sapphire RX5500 XT nitro+ special edition?
Is it possible to unlock the BIOS? This is the best I can get with the stock BIOS … if I try to set a Mem clock > 900 everything crashes…
Try 1100 core 725 VDD 850 Vddci 1250 Mvdd and 980 mem
Haven’t seen modded BIOS’ yet
If that doesn’t work for you
Remove Vddci, Mvdd and set Mem to 900
Then go up Mem by 10MHz steps until it crashes
Reapply Vddci and Mvdd

Try leave the core blank and rather change the memory to 900 and power limit 70
Then gradually add 25 untill you get the sweet spot
950 is safe on most cards
I had the same issue when I started adjusting the Core anything from 1000-1200
Thank you, I tried this: core blank, memory to 950 and power limit 70…seems quite stable with 27 mh/s. With memory > 950 I have invalide shares
You are most welcome.
Best is to then try 925 and see how it goes
Don’t worry too much if you have an invalid share or 2 in the first 24hrs
As long as its not continuous invalid shares
For those who have invalids with this OC and asus rog strix 5500xt you can use this bios (’‘performance’’ bios instead of ‘‘quiet’’ bios) :
Before with the quiet bios I got lot of invalid after mem reach 910 mhz now I can climb to 980 without problems (at 990 I got fatal error and my rig rebooted)

these settings are beast! dropped 30watts off my card lol
the best setting is 1200 core and 1025 Memory pl (non) I get 29.33 MH/S
but you should use the 0.6-203 hive os version to get it stable
card is
ASUS Radeon RX 5500 XT ROG STRIX OC Edition 8GB GDDR6 Graphics Card
stock BIOS
PowerColor 5500XT 8GB @>=28.09 day in day out using jhenberthon settings on a stock BIOS.
