Today I got my first VEGA 56.
The hashrate is max at 1940H/s but frequently it drops down to 1870H/s and then rises to 1940H/s back and so on.
Average hashrate (15min) is 1915H/s.
I am just wondering, because my Vega 64s with the same setup/mod have quite stable hasrates around 1980H/s +/-3H/s
This my setup: Vega 56 with Vega64LC bios to 1408/1100@905mV (regmod) and August 23th blochchain drivers
"gpu_threads_conf" : [
{ "index" : 0, "intensity" : 2016, "worksize" : 8, "affine_to_cpu" : false },
{ "index" : 0, "intensity" : 1736, "worksize" : 8, "affine_to_cpu" : false },
],
Any ideas?
Thanks and cheers
make sure you have fan RPM enough to keep memory cool.The hashrate is max at 1940H/s but frequently it drops down to 1870H/s and then rises to 1940H/s back and so on.

and gandalf's cast xmr does better with vega56 than xmr_stak
Meanwhile:
-I flashed the V56 back to stock bios
-removed all reg-mods
-Tested with xmr-stak -> same behavior NO constant hashrate.
-Downloaded and configured cast xmr and make it run with the stock & unflashed V56:
-> constant hashrate
-> with stock V56 hashrates above 2000 H/s possible. BUT it gets quite hot and more than 200Watt per card - undervolting etc. required
I guess the behavior is related to the combination of V56 and xmr-stak.
