Any word on amd vega hash rates?

[rednoW]

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.
and gandalf's cast xmr does better with vega56 than xmr_stak

Seems like a normal difference between 56 and 64(~3%)? Considering theres over 10% more shader cores on 64, 56s with 64s bios do well.

Maybe your 56 cant handle 1100hbm? I have 2 64s, 1100 and other is 1065 hbm capable.

You are right, Vega 56 is slower than Vega 64.
But this is not what I am complaining about.

I am complaining about, that the Vega 56 is going up and down in hashrate: between 1870 and 1940H/s.

And I repeat, its not carved in stone every vega can do even 1100mhz hbm Cool it down or lower the clocks like suggested.

oh it's cast xmr, i allready have this working

[th00ber]

FInally I got something functional !!
5 RX Vega - 8000 H/s - 750 W at wall

I'll tweak later

[teuflor]

someone tried the new driver to solve the 4/x Vega HBCC problem?

It doesn't solve the 4x Vega HBCC problem.

though for some rig...porn. This goes up/down literally :-(

I played round a lot, as well with cooling, GPU and HBM2 temps are below 60°C.
Maybe I give cast xmr a try, later

Temps are okay around below 60°C.
I testet lower frequencys for GPU and HBM2.
Even I flashed back stock V56 bios... (hashrate is between 1060H/s 990H/s)
-> Same behavior :-/

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.

My rig is Asus Z270-P/Celeron/16Gb/ Vega56 with 64 BIOS

I use this instruction:
https://www.reddit.com/r/MoneroMining/comments/74hjqn/monero_and_vega_the_definitive_guide/?sort=new

If I install 2 GPU - 130W per card
If I install 4 GPU - 160W per card

Why?

Hmm, I noticed that each additional card would add marginally more to my draw from the wall. Not as much as you're reporting - maybe about 5W/GPU (that is 1 GPU adds 130, 2 adds 135 (265 total), 3 adds 140 (405 total), etc.). I just chalked it up to extra CPU, lowered PSU efficiency, or something. Are you saying 2 cards bumps you by 260W, but 4 cards bumps you by 640W?

are you sure, that you applied the same settings etc. to all of your cards, even to the new ones?

BUT:

370W for 2 VEGA and 720W for 4 VEGA seems OKAY for my opinion.

I assume: 165-170W per card and 40W for the rest w/o VEGA cards

Your numbers are a bit off, then - what PSU are you using? Most are most efficient around 50% load (something like that, going from memory).
