Over Clocking help with CPU-Z
Over Clocking help with CPU-Z
Hey guys, I was trying to overclock everything and when I checked my core speeds in CPU-Z, I noticed that cores #1-5 are showing different speeds. One core is at 1200MHz, but others like #1, #2, #3, #4, and #5 are not displaying the correct speed. Is this normal? What should I do to fix it?
Assuming a turbo boost and your i5-8600K has six cores, the increase would be around 200MHz. At stock performance, one core would rise to four and a half GHz, two to four cores to four and a half GHz. A 200MHz adjustment would push the turbo to four and a half GHz across two to four cores, matching your observation of three cores at that frequency. When stressing the CPU, check if all cores stabilize around four and a half GHz or synchronize them.
Assuming a turbo with an i5-8600K on a 6-core setup, based on the 6cores listed? If I estimate, you've increased the frequency by 200MHz, keeping other factors constant. At stock settings, one core would rise to 4.3GHz, two to 4.2GHz with 2-4 cores. A 200MHz increase would further boost it to 4.4GHz across 2-4 cores, matching your observation of 3 cores at 4.4GHz and the rest near base speeds. Test a stress test to confirm if all reach 4.3GHz or synchronize properly.
I'm using an i7-6800K on an ASUS Rampage V Extreme motherboard. After adjusting XMP profiles in BIOS to set core speeds at 44 and DRAM at 3000MHz, all cores sync well. Running Cinebench achieved maximum performance without crashes, though games showed lower FPS.
It's strange. I assumed CPU-Z would display the 6800K as a 12-core processor.
Cinebench by itself isn't a confirmed overclock, which might explain your gaming issues.
I'd turn off XMP first—make sure your CPU runs smoothly at a reasonable voltage, then consider increasing RAM.
Changing the CPU can restrict your capacity to achieve higher, consistent memory speeds.

Hmmm, odd. I expected CPU-Z to list the 6800K as a 12-core CPU....
Cinebench by itself isn't a confirmed overclock, though. This might actually be why your gaming performance is lacking.
I suggest turning off XMP first—make sure your CPU runs smoothly at a reasonable voltage, and only then would I attempt to increase the RAM.
Changing the CPU can restrict your capacity to achieve higher, stable memory clocks.
Alright, I'll give it a shot! Thanks!

Cinebench by itself isn't a confirmed overclock, but it might be affecting your gaming speed.
I’d turn off XMP first—keep the CPU stable at a reasonable voltage before attempting any RAM upgrades.
Changing the CPU through BIOS can restrict your chance of hitting higher, steady memory clocks.
As I adjust settings back to their suggested values, only the 1,2,5 cores change; core 0,3,4 remain stuck at low speeds.
