CPU-Z showing incorrect multiplier range

post #1 of 2
Thread Starter 
I have managed to successfully overclock my i7-5820K to 4.2GHz, but I've run into an (probably harmless, but annoying) issue. CPU-Z shows the CPU's multiplier range as "12 - 34," despite the stock being 12 - 37 and my overclocked range being 12 - 42. It shows the correct multiplier based on the current CPU speed (so it will show 42 when the CPU is running at 4.2GHz), but the incorrect range bothers me.

In addition to this, Task Manager shows the incorrect max frequency. It lists the stock base speed no matter what I have the CPU running at. Like CPU-Z, it lists the correct current CPU speed, but in the table it lists the incorrect maximum frequency. I am aware that this is a known issue, but I would appreciate it if someone knew a way to get it to display the correct frequency.

Here is a picture of the situation from when I was running at 3.9GHz:




Thanks!

PS - Side note - is 4.2GHz at 1.15v considered a good overclock, or is my chip below average? Just curious.

Hmmmm

Same here. Task Manager, CPU-Z and OCCT. Task manager has wrong CPU speed, but here, CPU-Z shows correct multiplier.
