Sooo I have a bit of an unusual situation, almost nobody uses workstation GPU's to mine with, my project is over and now I have a "Radeon Pro Duo (polaris)" sitting idle doing nothing at all, it gets recognized as an RX 480/580 Ellesmere GPU which is basically what it is, but my problem is the largest intensity I can set is 2040 because any number larger just gets changed to 2040 and I am wondering if this is a software limitation? The GPU has 32GB total split into two 16GB chunks, one for each chip on the card, but it seems I can't use a full 2304 so every shader has its 2MB plus double memory enabled.
I don't suppose anyone has insight to this, I realize this is the 0.01% question but I just don't see anything stopping me from using 2304 intensity with double memory since that's only 9216MB which is well below the 16GB per chip on the card, it just changes it to 2040 when I use higher numbers.
Claymore 10.2
Windows 10 Pro
Blockchain Drivers
24GB System RAM (pagefile sizes up to 128GB tried makes no difference with or without one)
With intensity 2040 and a -20 power limit I get 1300 H/s and I can't help but wonder, what could I get if I was able to use 2304 instead, but it just won't let me set anything higher, it always changes itself back to 2040 on me, is this an internal limit since nobody expected a workstation card to be used?
try amd xmr stack
than you double or triple the gpu thread and try different king of intensities
start with this (470 4G)
{ "index" : 1, "intensity" :940, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 1, "intensity" :940, "worksize" : 8, "affine_to_cpu" : false },
then try 940+ until you find the best setting , and check gpu memory usage
the vega 56 use for 8G of memeory
{ "index" : 0, "intensity" : 2000, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 0, "intensity" : 1600, "worksize" : 8, "affine_to_cpu" : false },
after try with 3 x or 4x (but not sure gpu if fast enough to do it)
I've already tried this, tried numerous miners, tried various multiple thread tricks, they don't improve performance on the Radeon Pro Duo, so far claymore 10.2 at this 2040 setting it falls back to when I set higher numbers is the best H/s overall no matter what I do in the other miners, which is why I am trying to figure out if this is some hard coded limit because he didn't expect anyone to have larger than 8GB cards, it would be nice to see what 2304 with double memory enabled will do for this card and miner. no other intensity settings performed better, maxed was best, which indicates to me I have a lot of head room to go with this card, but I'm simply not able to capitalize on it yet, normally folks clog their cards and have to lower intensity, I seem to be in the opposite scenario where I am hitting some software limited wall, at least thats my assumption, I just don't know, which is why I am asking if folks know if there is a limit like this, its not like we can view source to find out so all I can do is ask and hope heh.
P.S. and yes I have tried 3 thread even 4 threads with those other miners, they always seem to choke on it, when I tried copying files to run two completely separate instances the program would kill itself, so I've tried everything I can possibly think of and have run out of ideas. I realize this is a workstation card so the odds of me finding someone with direct experience is almost zero, but hey its the internet, maybe I'll get lucky right.
