I wonder what is going on....  Shocked

I have 4 x 6 Vega64 rigs. All running with the same setup (OS, drivers, versions etc.)

When I applied the TRM 0.4.4 only one of my rigs got significant performance boost.

In this very rig 5 out of 6 Vega64 has ~2400H/s but one still has ~2100H/s and the same one has also regular interleave adjustments.

All the other GPUs in 3 rigs all have ~2100H/s and regular interleave adjustments.

I would like all the rigs to perform like ~2400H/s per GPU, but wonder what could be wrong with the most of the GPUs and rigs?

I tested 14*14 and seems that interleave adjustments are gone but hashrate remains ~2100H/s level per GPU.

The interleave adjustments aren’t always an indication of error, I have a few setups that need to adjust every 2 min or so per gpu.

The 2100 h/s is the normal Vega 64 hashrate at 14*14 or 15*15 before memory timings are applied. Have you verified that the memory tweak tool applied your timings correctly?

Last, what clocks are you using for your rigs?

I have optimized all the GPUs one by one. Rigs are stable now and Core is 1407Mhz with 860-970mV and Mem 1090-1100Mhz with 860-970mV. Power draw from the wall in these win10 rigs is 1320w in one rig and 1360-1370w rest of the rigs.

All the rigs have mixed set of GPUs in terms of Core and Mem clocks. There is also one weird thing too. The rig that got the hashrate boost with TRM 0.4.4. have overall like 70w lower power draw from the wall than the other 3 rigs.

Based on the mixed setup all the rigs should have ~ even power draw from the wall. I checked the HWinfo -> no signs of other differencies.

My GPUs did like 2020-2060H/s with TRM 0.4.2. and w/o timing adjustments. So 0.4.4. gives slight improvement in all the rest 3 rigs but major boost only one of the rigs (5 out of 6 GPUs in that rig).

Power draw from the wall increased 1320 -> 1420w and hashrate ~12%. In other 3 rigs hashes per GPU went only slightly up to ~2100H/s and rig power draw up like ~20-30w.
