Re: Has anyone managed to mine x16r with RX Vega GPUs properly?

So I'm trying to get a decent miner to work on my rig of 6xVega 56 (flashed to 64).

Tried Avermore 1.4.1: doesn't start after loading the kernel. Screen stays blank.
Tried Zawawa's GGS but it's not optimised and does no more than 10 MH/s per card.

Any more suggestions?

The first time you run Avermore it has to build the kernals. This can take like 5min or more so just wait out the black screen.

There is a initialization problem with the SGminer versions and Vegas. It doesn't matter how long I wait, the screen will stay blank.
One thing that will make it work, is to get GGS to initialise the cards, then closing it, and starting SGminer (whichever fork). That works every time.

However, I cannot get close to the speeds Marvell2 is claiming he's achieving. I'm averaging 12.5MH/s per card (whether I use Avermore, MadKernel or KL0nLutiy1's version). Not sure what I'm doing wrong... Sad

EDIT: what intensity/threads/clocks etc are you using? Some SGminer versions have a --benchmark function, some don't. When the miner fails, I'm never sure it's because of the parameters, the clocks, or the initialisation... Sad

Try -w 64 -g 2 -X 320 (worksize is 64, 2 threads, Xintensity 320) and you could use powerplay table like for monero.

Thanks. This gives me very inconsistent hashrates... Starting around 13.5, going down to 7... and totally different figures between GPUs... NB: I'm using Avermore 1.4.1 with --benchmark flag. Clocks at 1428/900 MHz @ 915/905 mV respectively. Driver version 18.6.1.

EDIT: it would seem that low worksize tends to increase this hashrate inconsistency. But regardless, whenever I find a setting that gives me close to 14MH/s, hashrate will drop a minute or so later. It's just weird. I run my fans at high speed so core temps are around 70C. I don't understand whether there is throttling or whatever is going on.
