How many millions of memory errors you have in 24h ?

No errors at all, i am running very loose custom straps

WTF man? ..

it was only a question

The latest drivers will do just fine. (Don't forget to DDU and set virtual memory to 20GB+, also try RX boost for a little more hashrate.)
Instead of using afterburner, try overdriverNtool - use it to find sweet settings spot for clock speeds and voltages.
If you want to push them a little more, use memory tweaker to tweak memory timings.

I bet you could fry an egg on that thing @ 33MH/s.

On card on my rx574 strix rig, when using rxboost gradually start losing hash, like in couple of minutes goes from 31.5mhs to 27mhs. Tried changing the OC and power no help. The strange part is now in phoenix i have the same issue (previously was very stable @30.5mhs). Any idea what else I could try, never experienced this ?

You are the first that proof the big increase that i was telling with core and rxboost :-)

Because of your mem errors your strap i bet yourstrap is to tight,i run 2150 without any error up to 2200

Yes the one click timings are very tight ones...
All depends on straps if you run pbe one time click pn samsung deny the 3.1.1 and use „slower“ the 3.2 and try 2150 mem

96w to 102w

Tried it, actually i lose 0.15 Mhs per card
