Signs of GPU memory OC instability

[moonedyou]

What are some of the signs of an unstable gpu memory overclock? i only know of one which is artifacts. can it cause games to straight up freeze and not respond? I'm trying to figure out if its my Core clock or memory clock because i'm trying to overclock my gpu its kinda tough knowing which one is unstable.

crashing indeed, but also lower values then before in fps for instance 
its best tested in some kind of program that depends on the gpu for certain actions, all of its actions for example as a gamer i tend to look at the games that would profit the most from the oc i'm trying. With i found out with my 1060 was that a to large memory clock would actually cause minor problems in a game but the real problems would start with a higher core clock.. i believe anything over an 125 point increase in afterburner ( without adding more volts ) would cause games to crash and lead to even more system instability when just running windows

GPU core memory controller and VRAM both can cause artifact, depending on the VRAM modules used on your graphic card they might not be very high compatibility for you to OC them 2 well together in the first place.

 

Is a hard to diagnose scenario because sometimes games don't artifact will still crash, and stress test program don't guarantees everyday gaming stability until you encounter a game crash, read graph for the last utilization spike or sudden drop before crash. Tune down something, stable the power delivery in Nvidia CP, and continue your days on. It can take months to findout a stability for all the games.

 

The best game i used for testing GPU/VRAM stability was Witcher 3. 3DMark and Heaven stress test would pass my OC and all games run fine except Witcher 3 will crash until i reduce VRAM to a near complete stock speed. Eventually i got tired and not wanting my VRAM to melt just to leave my expensive working GPU core render useless, nowdays i just run OC GPU and leave VRAM stock, no artifact, no crash, no worries.

Beautiful post man, excellen explanation!    OCed core will cause a crash but OCed VRAM will just give artifacts and what not.
