Hi guys, this is my first post to get some feedback on an overclocking attempt. I initially tried to go up to 4.5, but things just didn't seem to be stable (enough) even though at first all seemed well. I have achieved what seems to be a solid 4.3 using the settings below. I'm not a gamer, so gaming scenarios and loads will not apply. I won't be pushing this computer too hard most of the time, but do expect to have a lot running at the same time. I'd like to be able to bump up to a higher OC for specific tasks, like audio ripping/encoding (not professional) and batch image file conversions etc.
1) I would very much appreciate any comments or suggestions regarding this existing overclock and,
2) Any advice for best adjustments to push this to, say, 4.5?
My current 4.3 OC has VCORE between 1.344-1.352 volts at load (and 0.856 V at idle.)
With air conditioning running for stress tests, maximum temperature of my hottest core, with 15 hours of Prime95, was 82 degrees centigrade. Running AIDA64 (which is where I read my temps and voltages,) that stress test generally kept temperatures in the mid to high 60s, maximum hit 73 degrees. (I do realize these stress tests are not normal, everyday computing scenarios, and I am keeping perspective when evaluating the term "stable.") I also used Intel Burn Test.
Also, before CPU overclocking, but with XMP memory setting selected, I ran 3 cycles (12 hours) of Memtest86, with with no errors reported. I'm now entering my XMP values
manually, however.
Unfortunately my 6th CPU core runs about 10 degrees hotter than my lowest, and usually 6-7 degress hotter than the next warmest core.
At "idle" on this 4.3 overclock, the hottest core temp is around 34 degrees.
Here are my settings, and thanks in advance for your suggestions! 🙂
