I started to analyze the bios to understand wich bit change wich timing
this is what i found right now:
01 00 21 34 12 A0 22 8A 00 13 63 60 44 00 00 00 00 AD 2A 38 0C 73 28 22 0D 08 07 0C 0C 1E 01 10 0A 00 10 42
21= TRCDWA=8 (Good BW uplift (+35GB/s)and stable if set to 0(HEX>1C))
12= TRC=18
A0= TR2W=10
13= TRP_WRA=19 (Good BW uplift +8GB/s setting it to 16(HEX>10)
28= WR=8

WinAMDTweak.exe --current Results:
Spoiler!


Updated my custom set,now getting 450GB/s! HBM is FAST!
Testing memory with this tool, not sure if it's accurate, seems to stress the card, not like a AAA game. "Need for Speed - Payback" is the best game to test memory stability anyway.

And this is my latest "UberMixHBM v0.6". Based on the 400Mhz strap but with a lot of custom stuff and some 100Mhz strap bits .A lot better than the usual "TMOD" you can find online.
Code:
01 00 1C 34 12 A0 22 8A 00 10 63 60 44 00 00 00 00 AD 2A 38 0C 73 28 22 0D 08 07 0C 0C 1E 01 10 0A 00 10 42
Done some short tests:
Code:
//The Witcher 3 1440P Ultra (NO AA) (I like how i'm losing only 1FPS enabling AA at 1440P :rolleyes:)
Stock= 54FPS
UberMixHBM v0.6= 55FPS
//Superposition Benchmark 1080P Extreme (Best of 2 Runs)
Stock= 3220pts
UberMixHBM v0.6= 3245pts +0.7%
//Superposition Benchmark 4K Optimized + Medium Textures + DOF OFF + MB OFF (Best of 2 Runs)
Stock= 4975pts
UberMixHBM v0.6= 5061pts +1.7%
