Hey all
I have my 4670k overclocked at 4.2ghz. Running games its - so far - very stable. But when running prime95 torture and keeping an eye on temps, I noticed the chip would downclock as soon as it hit around 70c. I assumed this was simply thermal throttling so I disabled that in the BIOS but it still downclocked. All features such as c-state and speedstep we're also disabled.
I then thought maybe its getting too close to the max specified by Intel at 72c. So, I chucked two loud and powerful fans in my case and ran Prime95 again. This time the temps never went above 60 but the chip still downclocked after about 10 minutes or so. The motherboard temps also stayed below 60c. So im not sure its the temperature thats doing it. But beyond that, I have no idea.
Anybody know what might cause my CPU to downclock even though its well below the max temp allowed?
My kit:-
MSI H81M V2
i5 4670k @ 4.2
1060gtx
8gb 1600 ram
note: my motherboard has an OC section in the bios with basic features only. I can increase the multiplier but not the core voltage. I got it running pretty stable at 4.4ghz but dropped it to 4.2 to be sure im not overdoing it. Also worth noting that it managed 12 hours of prime torture without any errors. Only the downclocking thing happening.
