Driver keeps crashing - Crimson 17.6.1

[Gunna01]

I was running a 4 GPU rig fine and upgraded the mobo to support another 2 cards.

Reinstalled Windows, installed drivers 17.6.1(same version I was using on 4 GPU rig) and ran the driver patch. Now after about 5 - 10 minutes a GPU will fail in Claymore, i get a warning advising the display driver has stopped responding and sometimes the machine will hang. I tried updating to 17.6.2 but hash rate dropped down to 14mh/s.

Any suggestions?

Windows 10 Pro
Crimson 17.6.1
8GB ram
16gb virtual memory

I'm taking the risk and updating Windows to apply all teh current updates. I used a version 1511 installer so perhaps 1703 might resolve the issue

Give Crimson 17.5.2 a try. It's way stable than anything out there for 6+ AMD rigs. I've had an uptime of more than weeks with this driver and Windows 10 OS. You remember of uninstalling display drivers in safe mode with DDU, right?

I never do it via safe mode just launch it in normal mode. I got caught out going into safe mode previously and took ages to fix it.

Then you probably should use DDU in safe mode, you know that right? Incomplete uninstallation may cause a lot of issues. It doesn't take much time. You should give it a go once and see if it works for you.
