hi folks,
i'm wondering if sombody could help me out with my MSI rx 480 4gb gaming x hynix memory rig.
i'm only getting max. 21mh/s with a modded bios timing strap from 1500 to 2000, core clock gives me no difference, memclock 1900 gives me 19-20 mh/s and memclock to 2000 gives me 21.3 mh/s.
other timing straps gives me even more less..
at the wall i'm getting +- 140 watt each card.
since yesterday my computer even refuse to instal my cards. i already have multiple times deleted the drivers with ddu.
i'm using windows 10 and have try driver 16.9.2, 16.10.3 15.12, 18.2 all off the drivers only work with one card but when i plug them in all togheter they dont work, only the first time that i installed everything they all worked and where able to mine but only with 20.7 mh/s. my risers are all fine and already have try new risers and a new clean windows 10 also. but nothing works :s
when i plug everything in ,the fans are blowing normal but when i log in the drivers keep repeating to install my screen keeps flickering, like the cards are keep trying to install but it always fail.
hope sombody can give me some other suggestions that i can try.
trying to flash the original bios to see if that works is going to be difficult because i lost it..
i have found a rom the rom that i have flashed on techpowerup

1. You are risking to brick the GPU by flashing a downloaded BIOS image. Just move the 1500 or custom timing to 1750 to 2000 straps and overclock manually by MSI Afterburner or OverDriveNTool.
2. How many GPUs do you have and what's your MOBO? If 4+ GPUs, have you enabled Above 4G Decoding/Mining Mode? Above 4G Decoding works only in UEFI environment<>Windows installation must be UEFI as well.
3. You were getting low hashrate because none of 15.x-16.x drivers have the DAG fix (you are attempting to mine ETH or ETC, performance of both affected by DAG size) and the DAG fix was not activated in 18.2. I'd go with AMD 17.12.1 driver, it seems stable and enable Compute Workload for all GPUs (AMD Preferences>Settings>General>Gaming>select Compute Workload).

thanks for the reply's,
for the moment i'm installing windows 10 again,
The MOBO is an R2.0 pro btc asrock and i'm trying out 4 gpu 's
what would you mean with enable 4G decoding/mining mode?
when the windows is installed i'm already going to give it a try with the 17.12.1 driver, the timing straps should normaly be already set from 1500 to the 2000, going to try out the clock at 1150 cclock, 2100 mclock, 950 mvddc.
