Hey guys

I moved my system to new case today and had to setup few things, including switching on XMP.
I didn't notice that earlier but in BIOS advanced view Turbo was set at 4300Mhz and normally 4770K have Turbo set at 3900Mhz, right?
Is it connected to me switching XMP on?
Memory clock went from 1600Mhz to 2133Mhz.

Or is it supposed to be 4300Mhz and I just didn't notice it earlier?

Thanks in advance for the info :)
 
Some motherboards automatically override the default turbo. It is technically an overclock, and I think it's done as a marketing trick so benchmarks look better for the board.
 
I didn't change any CPU settings, mostly because I will be changing motherboard next month and there is no point.
I even run SuperPi with CoreTemp 1.0 RC6 running and it was showing Speed at 4.3 Ghz almost whole time.
Oh, and it was multiplier based.
Screenshot below ( woth CPU-Z running as well, for reference):

CoreTemp refreshes less often and sits at 4299Mhz almost whole time, CPU-Z jumps a lot, stay mostly between 4100 and 4199 Mhz but jumps to 4299Mhz as well.
Does chip revision may have anything to do as well?
Like some Haswells are good, some aren't. Maybe mine is good and wants very much to be oc'ed (and is giving me signs, lol ).

Hmm, I just hope it won't damage anything.
Right now I have an Asus Z87I-Pro motherboard, cpu cooler is Megahalems with 2 Akasa Apache PWM fans.

I would really prefer this wasn't happening on its own.
 
If it's anything like my z87-pro there was three system performance settings in bios. A green one...normal, & Asus optimal. Asus optimal tended to run at 4.3ghz (as shown in coretemp) while setting it to normal gave 3.9. HTH. Andy.
 
NP...Never realised myself at first some settings apply an oc....hope it's sorted.
