Problem on my MSI RX470, unable to see temperature GPU or memory or frequency !? in MSI afterburner and/or GPU - Z
All is in the title, this is so embarassing....
It's currently hashing at 22.5-23 MH/S on stock settings... Fan is at like 20% if its max throttle I guess.

Has anyone had that problem before ?
I tried 15.2 drivers 16.2.2 and now im on 17.4.2... I tried putting it on a different PCI-E with or without riser (16x slot directly) with no success.
I tried uninstalling and reinstalling afterburner many times.

Is my card broken ?   (I installed it today, its brand new).

I have 5 more of them still in the boxes about to get installed but I'd like to sort this out first :/

Any help would be appreciated by a little ethereum tip worth a cold beer

Hi, thanks a lot it worked, but now my other issue is how to actually run the overclocked mining rig without having to plug 6 screens is there a way to bypass that ? Or should I just use one dummy plug on only one card to unlock the settings of all cards ?
