Hi, I'm typically getting about 1850 h/s++(This card can handle 935 mem clock) and there's 2 card only can get 1808+ h/s (If I push further more than p3 910+ I got "Invalid AMD" using xmr stak and "!Rejected, nonce invalid" using cast xmr) with my Vega 56 powercolor red devil (Hynix memory) without flashing the BIOS. Any idea how to push my vega with hynix memory? I've been following guide vega.mining.guides.com but unfortunately still same. Only got 1808-1850 hashrate. (0.5 etc reward for best answer) thankyou~~~
My rig setup : Amdblockchain driver + Following Guide circusdad (Vega.mining.guide) using powertable P3 950/900 (But, unfortunately my card can't get pass 950. Most stable setting 905-930) P7 1407/950 .
My rig spec : Motherboard Asus Z270-P , 6x Rx Vega 56 Red Devil (Hynix), PSU 2xHx850I, Intel G4400, Ram 2x 4gb team elite 2400
My real Nightmare Problem : -Crap Hashrate can't get pass 1930++ hash -If I setup AMD txt on XMR STAK with double thread intensity 1932/1932 after a few hours later got freeze and I got massage "XMR STAK Application has been blocked from accesing graphic hardware" <--- this really annoying one.

I also used it and my Vega's run stabel between 1930-1980 H/s. Maybe you should use DDU and make a clean install on the Blockchaindriver. Maybe that guide helps you like it did to me.
