Did as you said - decrease the power target to -20% - and it's running without crashing for a day. Continue to test for problems. Seems it's the thermal issue
Cooler is very quality on your GPU. I think you will get a very good result if you apply a good thermal paste with 8watt/kelvin on the GPU. But this is voided GPU warranty. Increase GPU power with -15% or -10% according to 75-80 degrees if you want. In this way you will lower the performance loss. If you apply the best GPU power to your system according to temperature, your system is extremely stable for every application. You should also try GPU core clock speed with the standard value without changing voltages. The important thing is: Get the best efficiency from your GPU in the lowest temperature and most stable way... Good luck...
Yes. I'll test these settings to see if it's stable, then I'll increase something to find more efficiency. Turns out (and hope) that it's thermal issue only. Thank you
reduce the ram frequency to 700mhz this will reduce the bug 511 of the hotspot for me it worked but my gpu is a vega 56 msi in this way I can play even 2/3 hours in a row but in any case the fault remains I think it's a defect of some cards with windows 7 it occurs less than with win 10 I spent hours experimenting .... try my suggestions
I'm setting the ram to 680 mhz this seems to solve the problem for me and in any case you don't lose a lot of performance always better than throwing it since having mounted a morpheus2 cooler I lost the guarantee.
look for the ir35217 controller on the back of the circuit board and if there is no 2mm thermal pad this solves several temperature reading problems and random crashes since it is not cooled on most boards.
