Allow to specify timing straps to apply from a list of gpu vendors

[wilvk]

for example, the C# polaris bios editor has the option for specifying timing straps from a list based on a gpu vendor. see below:

string[] timings = new string[] {

Here, too, found the conformity of the manufacturers and models of memory

Dictionary<string, string> rc = new Dictionary<string, string>();

rc.Add("MT51J256M3", "MICRON");
rc.Add("EDW4032BAB", "ELPIDA");
rc.Add("H5GC4H24AJ", "HYNIX_1");
rc.Add("H5GQ8H24MJ", "HYNIX_2");
rc.Add("H5GC8H24MJ", "HYNIX_2");
rc.Add("K4G80325FB", "SAMSUNG");
rc.Add("K4G41325FE", "SAMSUNG");
rc.Add("K4G41325FC", "SAMSUNG");
rc.Add("K4G41325FS", "SAMSUNG");

Thanks! Will get to it soon.

this is a function of the c # version, I think this will help

Thanks for this. Haven't forgotten, just been super busy lately.

[wilvk]

A temporary workaround for this has been implemented as, for example:

./pbec -i test2.rom -o test2.rom -n aaaaaaaaaabbbbbbbbbbcccccccccc333333333344444444445555555555666666666677777777778888888889ABCDEF -p 1

how do we use this, is there a guide
I have a K4G41325FC samsung sapphire rx 470 4gb (one dvi)

[smlyclts]

K4G41325FC samsung sapphire rx 470 4gb (one dvi)
