RX VEGA and RX 470/480 Very bad hashrate

[fabry1999]

Hello,

I have a RIG with a RX VEGA 56 and other 7 GPU (RX470 and RX480), when I run all toghether with Cryptonigh I have jus 800 H/s on VEGA, but in other PC just with 1 GPU RX VEGA the hasrate is 1950 H/s why this different behaviour ?

Hi, just switch  to XMR-Stak  or Cast-XMR  and your will reach 1900-1950 H/s  with RXVega 56/64

P.D. Cast-XMR its optimized only for Vega.. its not recommended mixing it with rx470/480

To clarify what the previous poster mentioned, you will have to use 2 separate miners.

1 miner specifically for your 470/480 cards
1 miner specifically for your VEGA 56

For the 470/480 cards you can use claymore's cryptonight miner
For the VEGA 56 you can use Cast XMR

I  have use two different miner Cast XMR for Vega and XMR-stak for other RX but I had the same result !

then on  Radeon tool I can't set the HBCC, just enable and is not possible select the amount of memory that now is fix at 9GB while previous was 15GB.

I think is not possible use both card on same rig, anyone have this mix card RIG working correctly ?

I have mixed 1 x RX570 and 2 x Vega 56 working perfect with one instance of Cast.

You have to tweak your vega in order to get such values
use this guide

Once done you would be able to reach 1900 h/s per vega gpu

I did and it works perfectly alone on other PC but when i put in a RIG with other RX GPU the hashrate is bad !!!

you've said what the problem is many times, yet you do not pay any attention to what the solution is, PUT THEM IN DIFFERENT RIGS!
clearly rx 400 and prolly 500 series gpus do not work well with the vega installed in the same system. solution make a vega rig and a rx 470/480 rig.
