placing only --4g-alloc-size 4080 or 4078 without placing anything else you still have problems?

i was using a splitter so i just switched mobos to one had 6x pcie slots
nothing worked for me in regards to settings
other than this im thinking the splitter does not actually run gen 2
or it splits the bandwidth so much zombie mode just crashes

these are the 5 cards that are causing low hashrate is what im thinking
that looks exactly like a pcie splitter but built into the mobo
im assuming zombie mode takes the extra bandwidth from the loss of hashrate and gives the extra to the memory channel
or something like that to counter TLB thrashing
thats why we need gen 2 is for the bandwidth im thinking
there might be some combination of removing cards that would at least get a couple to a few of those 5 cards at current full hashrate if it happens in the future
or just 1.19 fixed the problem we were having and im thinking way too much into it

You have a bottleneck in that PCI... that's the problem you have... you have to think that the extra DAG to run in Zombie mode has to be in system and the only option to go to system in the cards is by PCI... that's the bottleneck Complicated to solve...
