2000 degree vram?

[abrackers]

I recently got a Vega 64 LC and am trying to OC the vram. I am using the newest 2020 drivers which auto suggested 1051mhz, which works fine in folding@home with no errors. However it crashes the gpu drivers with "radeon host application has stopped" in half life alyx and in superposition benchmark. Testing 975mhz also crashed the driver in superposition. I then tested stock 945mhz in superpostion and it works, but afterburner reports rediculously high vram temp spikes.

Anyone have any idea what could cause these, if I should be worried about them, and if there is anything I can do to OC my ram without having the driver crash?

The temp reading has to be a bug of some kind.  

F@H doesn't use VRAM very much if I recall.  The other benchmarks are a better test.  

GPU clock would be a better OC for F@H.

Thank you. Yes I guessed it was a bug. Just worried it might be indicating something in the gpu core dying.

I was point out folding because it was a very good indicator of vram stabality with my previous gpu (It could run games fine but needed a vram uc to not get errors). Also, the vram oc did significantly increase ppd (1.05m ppd - 1.2m ppd)

Does anyone with a vega 64 know, should I also be adjusting vram memory timing settings, or vram voltage while overclocking it? I am overclocking in the radeon software.

I have now figured out why I couldn't oc vram past stock. I gave +50mv to vram voltage (which actually controls soc) so its now 1000mv and I can OC vram to 1100mhz
