Intel I7-7700k on Asus ROG strix z270E, XMP or turbo boost which to choose ?

I have this simple problem with my proccessor (Cooling Dark Rock 3 NOT PRO). When I turn on XMP (g-skill Rijpjaws V 3200mhz) and my turbo boost is turned on (4,5ghz). The temperature skyrises over 80 even to 90,then i offseted my CPU (0.065v) (v-core gets max to 1.2~1.84v) and it still goes over 80 degrees... Lowering the turbo boost to 4,4 mhz manualy (or setting it on auto it lowers it to 4400 too) the temperature reaches (after 10 min stress) 83 (two of the proccessor cores) and vcore is just 1.152 max through whole the stress. So I was wondering if ts worth for me to keep that XMP on ? cause I what i noticed when the xmp is off and the proccessor is offset to 0.065 with turbo boost on the proccessor only reaches 70~ degrees. Is worth to keep XMP on ? All I do is just gaming (PUBG and so on) or should I lower the proccessor speed and turn on xmp (runs in safe temps with 4,2 speed) ? And are these temperatures normal for such a vcore voltage on a dark rock 3 air cooler ? Some of the bench pics below on different speeds and with and without xmp http:// http://

turn off multi-core enhancement (MCE, it basically runs your all core frequency with the highest turbo clock, with AUTO voltage. this leads to huge increase in tmeperature), i think it's a feature for asus where when you turn on xmp, mce will get turned on.

you can always manually overclock the 7700k or having it on default turbo boost.

Before turning XMP on it asks you do you want to OC your proccessor you just press No and it only adjust RAM settings (you can see it before saving everything in the bios what was changed). Turning MCE off or leaving it AUTO just makes everything the same no changes at all.

Leave XMP on , lower the memory voltage if you can. I recall that shaving a few degrees off my CPU, though if stability suffers you can increase it back to where it is set, likely 1.35 volts.

90C is a bit high, but low 80s isn't too bad. So see what your max temp is for games, chart/log it if you want to see how long it stays there.

AIDA64 is pretty heavy duty testing, so if you got through that without hitting TJMax then it should be fine for everyday use.

yea but low 80s only at 4400 speed ;sss. As I see you got a I7-7700k how was your vcore before OC'ing it and the temo too was it hot ? I mean did you have offset it or what did you do (mb nothing 😀). Never tried to play with RAM voltage dont even know how to start with it.

Core voltage before overclocking was a ludicrous 1.35 volts, there is a picture of it somewhere in my build log. Good thing I used a massive cooler when I did the first test. Not that I ended up too far off from that, it sits at 1.416 volts for stability, but it is water cooled and delidded.

Simple setting for the memory voltage, you can increase or decrease it. There are also a whole host of other voltages inside the CPU you can change. If any one of them is set to a high value it could be the source of the problem.

Also Intel hasn't been very good with quality control on their thermal compound application. It could be that you just got a not so good chip. Delidding can usually take care of that, but if you can't afford to replace the CPU, do not attempt.

With an average size cooler, I think low 80s is expected. If you compare the CPU to the i7-6700k it is basically just an optimized and overclocked version of that. I don't think they tried too hard to achieve low temperatures, they were after performance.
