I am testing lolMiner 1.22 (linux) with 40 GPU's (all 480/580/570 4G)

Resuts:

1) All speeds are always better than TRM
2) There are no rule to get better hashrates some cards go to 15MHz, some to 13MHZ, one goes to 25Mhz and other identical card on identical Mobo goes to 13MHz...

I think it will be nice to have a special instructions detailed for us to get the better hash on 4G GPU's.

PS: Enable 3Gen PCI not always meaning more hash on my tests

One of the important things is the PCIx8 or PCIx16... so that is also a bottleneck, lot of cards will give also a bottleneck if all the PCILanes are used... These is the reason why sometimes only 1 card is giving the max perfomance too...

The autotune made by the developer is great, but normally is hardware bottleneck.

so, it has nothing to do with the driver version or a specific linux kernel version?

but the readme file says

The higher this parameter is choosen the more memory for a partial dag lolMiner
is allowed to use. Thus the speed on your 4G cards will increase significantly.
Given a recent driver (e.g. amdgpu-pro 20.30 or 20.40) and the right Linux
kernel (best is 5.4 at the moment), you can almost always set a value of 4078,
on many rigs even 4080. Older drivers or other Linux kernels may require sig-
nificantly lower values and will perform slower.
