CPU Unpark

[ishraq2626]

I have a i5 4690k and i used the CPU unpark tool.

It shows only three cores which are Core 0,1,2

But my CPU has four cores,why is it like this?

Can anyone with the same CPU confirm,

TIA

Windows 7 can only park physical cores, so it doesn't do anything on an i5

But i have seen my CPU usage increase a lot in games like crysis 3 with little to no fps diffrence.

Does unparking cores increase CPU Usage?

It should decrease it,.. instead of 2 main threads running on core 0+1 with 2+3 parked, it should...hopefully unpark, and balance the load a little bit more, even if its 10% each on core 3+4 thats less load on the first two cores...

Thats if I am thinking correctly...

check your bios to make sure you don't have any disabled cores there. i did use the core unpark tool with my i5 and i have 0 issues what so ever, no point in using it as intel cpus are quite powerful. it helps with amd because of the CMT architecture.

i checked but i still see that CPU1 usage is high than the rest.

I ran Games,benchmarks and the same result.

Windows 7?

 

1. go to your registry
2. search for this key: 0cc5b647-c1df-4637-891a-dec35c318583
3. change value max to 0 (zero)
4. Repeat these steps a couple of times, the key can exists multiple times.
5. reboot system.

That's normal. A thread can only be processed by one core and some threads require more work than others
