One core higher than the other

post #1 of 5
Thread Starter 
Hi, I was wondering is there any benefit by clocking 2 cores higher than the other? I have a i5 4690k and I have OC it to 4.5 and it won't go higher without upping the volt. So I tired OCing the first two core to 4.6 and it's stable without increasing the volt. My question is are there any benefits by upping those 2 cores?thanks

There are, find out how much by running benchmarks- cenebench or if you have an asus or msi motherboard, you can use ai suite or msi xtu.

You misunderstood. Those four Turbo Boost multipliers you are thinking of are really doing something else. They change the speed for the whole CPU depending on how many cores are working or sleeping.

The higher values you configure get activated when Windows puts unused cores to sleep. For example, if you configure the multipliers 38, 38, 37, 36, this means that the CPU will run at 3.8 GHz if two or three cores are sleeping. It will run at 3.7 GHz if one core is sleeping, and it will run at 3.6 GHz if all four cores are working.

You can't choose which cores exactly will be running at what speed. It is not possible to run certain cores at different speeds. The whole CPU will be set to one speed at all times, and that can't vary between the cores.

so if i understand you correctly there is no benefit upping those two cores if all four cores are running.
