Thanks...I think I figured it out now...at least how it is working.  I have yet to get the date sheets on samsung HBM2 but I digress.  Anyhow it seems setting it lower then then default does nothing....after I checked what was told to me I was using extreme values to check.  However actually raising it has increased my hashrate but I now I am not sure what the range is...but guessing it is just a range...and anything out of that range sets the default.

@eliovp sorry I do not know how quotes works on this forum.  

Anyhow HBM2 on vega64 with Samsung.  It does not seem to matter what setting you put in.  I can do some screen shots.  I mean the tool reads the setting you imput...but it does not have any actual effect on anything...as if it is being ignore.  Unless I missing something.  Other timings are working and do change things.

@eliovp can you check something tCL does not seem to change anything.  This was pointed out by someone else on reddit.  Anyhow I tested it, and it does indeed seem to be true.  You can set the tCL value to 0, 1 up to 50.
