Low kh/s on 14.1 drivers?

[IBIubbleTea]

Not sure if I'm the only one but when I tried mining today with the new 14.1 drivers, I got a really low kh/s on my R9 290, about 100-300kh/s. I when back to the 13.12 and I'm getting my normal kh/s which is 820kh/s. Anyone else?

They're beta drivers made for Mantle? Stay rolled back to the latest stable.

Yeah, don't mine on beta.

I'm at the exact same hashrate for one of my mining rigs.

I own a 290X. I'm still mining at 870KH/s with 14.1. 

I'm using sgminer 4.0.0 though, which is updated, as compared to cgminer 3.7.2 (which is effectively dead). I suggest using sgminer if you aren't. It's great. You can use the same .bat file, just remove --scrypt because it's forced and so it's pointless and replace the c with s in cgminer. It's that easy.

They use the same .conf files too, so just do the same with cgminer.conf

But yeah, I have no idea other than that. Try tweaking your settings. It could be an update that affects optimal mining settings.
