Hi, A strange CPU behavior has appeared yesterday. No matter, what I do, it rapidly heats up, and cools down.
In idle it's 30c and stable. E.g I lauch browser - temp goes up to 50 or even more. (monitoring in aida64 and mobo onboard display), after the browser has loaded (1-2sec) the CPU goes back to 30c very fast. CPU fan rpm goes up and down, while the CPU temp jumps.
I click any link, open any document/programm (heavier than notepad or paint) and cpu temp jumps 30-55 and back. In BIOS the fan is set to quiete mode.
CPU cooler attached well. (I think the temp wouldn't be 30 in idle if the cooler was loose).
While I'm rocking intel HD630 (waiting fot gtx1080ti) there is nothing to really threaten the CPU in terms of temp, so I'll leave everything as it is. Interesting...can i opt for a warranty replacement?
If you want to let it at 1.30v that's fine but I'd get as much out of the cpu you can at that voltage. I can pass the Realbench stress test at 5.0 GHz with 1.312v so I would think you should be able to do 4.8GHz - 5.0GHz with 1.30v.
You're actually at 1.356v so 1.30v is lower voltage.
The first thing I will have you do is reset the bios to defaults (F5).
On the Extreme Tweaker tab set the AI Overclock Tuner to Manual, scroll down to Dram Frequency and select 3600MHz, scroll down to Dram voltage and enter in 1.35v.
Then go to Dram Timing Control and enter in the timings at the very top.
16 16 36 2N
Then hit F10 and Enter
What we did is reset the bios to defaults and set your ram manually, if you make it to windows you can run the AIDA64 ram test. If you're greeted with the overclocking failed message then we'll have to do a little tuning.
