The GPU has 2 x 8 pin connectors. I have slotted in a 6+2 connector into each.
I have PBO enabled now (I removed the 65 wattage) but what is CO?
The cooler is a Noctua NH-U12A and this has been refitted with new new thermal paste, problems persist though.
I have subsequently enable XMP and removed the 65 Watt in the Bios.
It is not in Eco mode, I cannot install the Ryzen software to enable this due to the Windows installer error.
Usually the game crashes and I am staring at desktop, sometimes it's blue screen and it takes several attempts to get to the Windows login screen.
OK so I managed to clean install and ...... problem persists and games crash after a few minutes.
Openly sobbing now.
This thread burns my brains, so sorry if I'm asking the same questions again..
Memory
Please disable XMP/EXPO/DOCP and do not touch anything in the BIOS (i.e. do not manually change the frequency).
From one of your screenshots, I think I saw that you have 6400 memory, is that right? This could be a problem, so just leave it running at default (probably 4800) for now.
Have you run memtest or similar memory testing software? If not, do that ASAP.
CPU
Please disable anything that is not stock. This includes eco mode, manual TDP changes, undervolts, PBO and curve optimiser.
Graphics card
Scale back any overclocks, use the default, quiet or whatever VBIOS, if a switch is available. Do not use afterburner or similar software.
Motherboard
Don't change anything in the BIOS, don't install Ryzen Master.
Software
If anything is running while you play your games, kill it with fire. If you have RGB software, uninstall it. If you have motherboard software, delete it. If you have PC tweaker software or PC SUPER BOOSTAAA+++ just, .. argh.
SSD
Do you have a 970 Evo Plus?
If you do, download CrystalDiskInfo and post the SMART results here.
Check your firmware is safe (not one of the affected ones).
