atomicWAR :
it will only hit 3.6ghz when using a single thread AND it has the thermal headroom to do it. So my first question is what are your temps? What program are you using trying to get boost to work? Did you make sure turbo was enabled in bios/uefi? Also since you brought up you got the CPU are you 100% certain you got a retail model and not a engineering sample? This sometimes happens when buying used/heavily discounted CPUs.
Answers:
1.) Temps at full load is around 62c which is weird because its so damn hot here in the Philippines right now
2.) I used Cinebench and it will constantly run at 3.4GHz. However, using Prime95 at small fft's it will go to 3.6GHz on 2 cores and will eventually plateau again to 3.4GHz.
3.) I did some work on the UEFI settings but to no avail.
Also, on single-core benchmarks like the one built in with cpu-z, it hits 3.6GHz consistently with core 0 and core 6 (alternating between the 2. I dont know why tbh) But, if i were to adjust the clocks on UEFI, it wont let me set 2 of the cores below 3.3GHz. I cant even underclock the CPU which should still be possible even with a locked CPU. This is all new to me sorry. I had an AMD system before I upgraded to Haswell
