Is it safe to create artifacts while overclocking the CPU? Need some guidance.
Is it safe to create artifacts while overclocking the CPU? Need some guidance.
I recently built a new machine:
Core i7 6700K
Sapphire R9 390 NITRO
Asus Maximuss VIII Ranger Z170
32GB G.Skill DDR4 @ 2400
2xSSDs + 2xHDDs
750 Watt Thermaltake Tough Power
Very odd issue I'm having is when I attempt to very slightly OC' the CPU - When going from default 4.2Ghz (turbo) to something like 4.4 or 4.5 Ghz , the system will reboot and POST fine. But windows (especially chrome and web browsers are getting crazy weird artifacts on the screen).
This is something I would expect to see when I'm overclocking my GPU, but not my CPU. I've been very careful to increment my CPU voltage as I OC the multiplier... but still the issue seems to happen. My only hypothesis is that I'm starving the GPU for power? But this seems rare, as when I game / perform bench marks without any OC's - there are no issues.
Any help would be GREATLY appreciated.
It's odd, but I usually see artifacts only when I push the VRAM overclock or let it overheat. The other possibilities I can think of are insufficient power going to the GPU. It might be worth reconnecting all the power cables. Also, have you tried reinstalling the drivers?
Lol @meself I got mixed up, don't worry about my previous message haha I was thinking about something else lol
In any case, I'd make sure to check all temperatures, especially the GPU. Because if your CPU is getting too hot, it could lead to VRAM overheating and artifacts.
I got a bit mixed up with my previous message, but I’m sure you meant something else. I’d like to double-check all temperatures, especially the GPU and CPU, since your case tends to get hotter than expected. Overclocking has made the CPU idle high for several seconds, often reaching 60s or more, and sometimes hitting 70 when under full load. The GPU is running in the 30s range, getting warmer with higher loads. These readings don’t seem out of the ordinary for me. Thanks for your prompt reply!

Yeah that's weird. The only time I would see artifacts is when I go too high with the vram overclock and/or overheat it. the only other thing I could think of would be lack of power to the gpu. Maybe worth re-connecting all thepower cables?
Also did you try re-installing drivers?
Again, thanks for tips.. Have not yet tried reconnecting all power cables. Probably one of my next steps.
The only other possibility here that comes to mind
is my 750 watt PSU is a few years older, and only had 1x8pin GPU power connector, the other 3 were 6. As a result, I bought a 6 to 8 pin adapter.
Before jumping on that as the 'culprit' though - I'd like to point out, I've been doing mild gaming, (Crysis 3, Starcraft 2) at stock settings - when I'd expect the GPU to be using load, and have no had any issues during gaming sessions.
