I've not found any problems with the system, but WUs keep erroring out at almost the same time (2-3 sec after start). Is there a specific reason for this or something to do to avoid it? I've tried different drivers but this does not change anything in overall, still errors.

I have the same problem.

Since today all workunits ends with an error:

oh it seems a restart solved my problem

I'm on Crimson ReLive WHQL (17.8.1) driver, GPU all stock.

my error rate dropped dramatically after I stopped doing test WU's.
Even though it was not test WU's having all the errors.
Strange

Will, test. Thanks.

Made no difference in my case.

I've upgraded to 17.9.3 WHQL drivers and will see if it makes a change.

NVIDIA on windows 10 gets this error on every task. AMD works fine.

I had a major reduction in errors when I switched a card from Nvidia to AMD

It appears we agree then. NVIDIA cards are useless on this project at the moment.

All my errors are on Vega64 ReferenceEdt.

Does not matter if stock, stock undervolted, stock powerlimit upped, stock maximum fanspeed. The error ratio from WUs completed successfully is about the same.

There's 0 stability issues with the computer/gpu otherwise. GPU @59C and HBM2 @65C (host is located in 16C ambient serverroom).

I don't know if it will help you, but it helped me to reduce error rate from 100% to 10% by reinstalling MS visual redestrucatbles 2010 and 2015 both x86 and 64-bit. Also it's seems to be Windows 10 issue, other people with similar cards but on windows 7 computing my failed units without error.

Using AMD RX 580 red devil, GTX1060 3gb and HD7970 ghz edition on 3 different computers, error rate 10% is the same, all windows 10, so it's not driver or manufacturer issue.
