You may not see full all-core turbo unless your cores are loaded heavily enough. If you find this is a problem for some applications, particularly games, you can use something like system explorer to set and retain affinity and priority settings so you are more likely to turbo when running them.
Also, is that E5-2690 v4 an ES proc? If it is, make sure it's a QS or QA proc as early steppings could be buggy. Got burned a while back with some "E5-2667 v3" procs that were cut-down 14-cores with the 35MB cache, these procs would boost across all cores and then for no reason at all just down-clock to 12x multiplier while under full load. Essentially, completely useless.
Luckily I was able to get a full refund on them.
Most games don't seem to be properly optimized for multiple threads, and even the ones that are multi-threaded do not seem to be able to utilize the threads fully. Exception to this is Battlefield 1, that game utilized 8 threads pretty effectively and utilizes GPU very well. The previous couple BF games may also be the same.
Fallout 4 seems to utilize about 8 threads max, but the game is poorly optimized so it runs like shit whether you are getting full turbo or not. I restrict it to 8 threads and it seems to do well enough on my current E5-2690-0 build.
Thank you for the ifno.Im not exactly sure what you mean by ES processor(qs/qa)Kind of lost with the terminology but i suspect you mean the engineering samples that you can find on ebay cheap?Ive read those for example some times dont have hyper threading or lower clocks.The one i was looking was this one (page in spanish) which looks like the ¨¨full version¨¨?
