Decode memory timings from the given timing string. #5

Will it be possible for you to make your tool be able to decode values from the given timing string? For example

./amdmemorytweak -s 777000000000000022CC1C00AD615C41C0590E152ECC8608006007000B031420FA8900A00300000010122F3FBA354019

So the ppl can actually use it for learning what's the difference between the default and moded timings. It will speed up the learning process for average users.

Hey,

There are already a few tools out there that do that :)

Cheers!

i'm asking because it seems like OhGodADecode tools give different values

Also, if you compate MISC values from you output to amdmeminfo output, there is a difference too.

sudo ./amdmeminfo -c

R2R is missing now in CAS section.

Got that all sorted in next release. (any day now 🔢 )
