Hey guys, I was starting to overclock everything and when i went to check my core speeds in CPU-Z, i have cores #1-5 on a 6800k but only 1,2,5 are showing the right speed. is this normal or what do i have to do to fix this

#0 Core speed: 1200 Mhz
#1:4400 Mhz
#2:4400 Mhz
#3: 1100 Mhz
#4: 1200 Mhz
#5: 4400 Mhz

Assuming a turbo and you're running an i5-8600K, based on the 6cores shown?

If I were to guess, you've bumped by 200MHz, without adjusting anything other than clock speeds/voltage?
At stock, 1 core will boost to 4.3GHz, 4.2GHz on 2-4 cores.

With a 200MHz bump, that turbo will scale and go to 4.4GHz on 2-4cores, which would explain your 3 cores running at 4.4GHz and the balance running near the base clock speeds.

Run a CPU stress, and see if those all level out at 4.3.GHz (the stock is 4.1GHz on all cores), or sync all cores?

I am running an i7-6800k, with an asus rampage v extreme motherboard. when i went to the bios and picked xmp profile to change the core speeds to 44 and dram to 3000 mhz, i also have all the cores syncing. i ran cinebench and got it to the highest without any crashes but i noticed my games were running lower fps.

Hmmm, weird. I thought CPU-Z would show the 6800K as a 12 "Core" CPU....

Cinebench, alone, is not a verified overclock though. That could well be the cause of your poor gaming performance.
I would disable XMP initially - get your CPU stable as high as you can (with reasonable voltage) and only then would I try to bump the RAM up.
OVerclocking the CPU can limit your ability to reach higher, stable clocks on the memory .

As i go back into bios to change everything to their recommended, the only cores that change are the 1,2,5 again. no matter what i put. core 0,3,4 still stay at that low MHz
