Hello!

I'm getting green screen and reboot if VRAM fast timing is enabled.

I'm OC my GPU but it won't crash if VRAM fast timing is disabled.

Is that a Driver Issue or GPU issue or dunno hehe?

My build:

Ryzen 5 5600X

Sapphire Nitro+ RX 6700 XT

G.Skill 32GB RAM 4000Mhz

PSU 850W 80+ Gold

Edit: Forgot, my driver version is Adrenalin 21.8.1 Optional

Hope seeing some good tips

I am getting the same issue with rx6700xt power color red devil, I slightly overclocked and changed the fan curve to my liking but this doesn't affect anything , when I change from default to fast timing I get green screen , crash then reboot . this so far happens with rdr2, I also realized it also affects my hdr to switch on and off time to time . But with it on its really an increase in performance.

Running the Power Color Demon RX 6900 XT.

Had same problem.

Found that if I don't push the memory clock past 2200MHz and don't push the GPU fans over 75% the issue stops.

Been running my VPU at 2235MHz and VRAM at 2170MHz (fast timing enabled) for almost a month now with these settings and no crashes green screens black screens or no signal have happened.

My build Windows 10 Pro 64 Version 21H2 CPU Ryzen 7 2700x at 4.2GHz 32GB Corsair Dominator Platinum (4x8) PC3200 RAM MOBO MSI X370 M7 ACK SSD Samsung SATA 3 870 EVO V-NANO 4TB GPU RX 6900 XT with WHQL drivers PSU Thermaltake ToughPower 1200 watt CPU Cooler MSI FROZR L 120mm x 2 fans. 

Probably teething issues with the GDDR6 VRAM.

I remember when ATI came out with the x1000 series GPU's with the new GDDR4 VRAM they had similar issues with the higher end cards.

A few days ago I just read that maybe fan vibrations could be causing some sort of EMI

(User said that manually set fan max speed to 70% made crashes and reboots disappear - If set above 70% would crash and reboot)

Weird thing

That would be me. 

Every crash I experienced on my Power Color Demon RX 6900 XT happened when my GPU fans were set to 80% or higher.

For a month now I've kept my GPU fans at 75% with no thermal issues on any application and no "Global Wattman has reset Adrenaline software to default for unknown reason errors".

Also experienced the same issue when I was running 2 RX 590's in crossfire. Fans above 80% frequent crashes fans at 75% or lower no crashes.

Don't know why this happens but I know desktop PC's are sensitive to vibration physical shocks/impacts and Electromagnetic Interference.

New info:

I have Adrenalin 22.2.1 Optional drivers and most games work good.

Fast Timing enabled and GPU and CPU overclocked.

***** Except for Dota 2 - I had some reboots with black screen, weird thing is I enabled Vsync and no more reboots.
