Question Cooling and Overclocking i7-14700K

[Ahmeddux]

Hello guys, i just updated from core i5 to the lastet core i714700k, im not getting the results i expected to be honest also the cpu some times goes to 100c, in no use status the temp is 35c average, i tested the cpu in intel exu i get score of 10650, and throttled cpu, is this a manufacturer problem or its hardware, knowing that i have Air killer-s cooler, and proper thermal paste, motherboard is asus b660 prime plus d4, and 64 gb of ram, ill attach screenshots, and i would really appreciate any help, https://ibb.co/TqXcGyB

that little air cooler not enough

And Asus b660 prime plus d4 is not enough too...

That air cooler has a 160W TDP rating. Your Core Temp screenshot shows the CPU is running at 221.7W. You cannot get maximum performance out of a 14700K when using that air cooler.

The latest BIOS versions for motherboards with the B660 chipset enable Intel Undervolt Protection. The default voltage when using K series CPUs on B series motherboards tends to be on the high side. With UVP enabled, there is no easy way to fix the problem. Some users with Asus B660 motherboards have a BIOS option so you can choose to run the early 0x104 microcode. This microcode version is the last one that allows undervolting. This can help reduce temperatures significantly if you are willing to play around with this.

Even with an undervolt, your cooler is still inadequate. You can try lowering the turbo power limits in the BIOS to default values. This will reduce maximum performance but it can help keep your CPU from constantly thermal throttling. Intel 14th Gen CPUs are ovens when allowed by the BIOS to run at full power and full speed.

Hey i just changed the cooler, to corsairs icue elite capelix 240mm, and even after increasing the power limit im still getting the same performance as when the cpu on 130w power limit, this os making me crazy, any solution?

 

[Ahmeddux]

I just installed a brand new 240mm aio from Corsair and i was surprised that im getting se score as my last budget air cooler, even though the i installed contact frame and opened the power limit in the bios, how come 130w power limit score 27000 in cinebench r23 and 253w score 26900 like what is happening, im pretty sure o installed the cooler right, any idea whats going on. Cpu is i7 14700k, cooler Corsair icue elite capelix 240mm.

Cinebench isn't exactly a comprehensive test. If your CPU wasn't throttling during the test before, it wouldn't now, so the scores should be similar.

Did you make note of the clock speeds during the runs before and after the upgrade?

With more cooling overhead, you can now increase the power and increase the clocks on the P cores and E-cores. Though in Cinebench the E-cores make up a lot of the score.

If your goal is a higher benchmark score, add a few hundred Mhz to the P cores and a smaller value to the E-cores, usually 100-200Mhz is all you can gain there.

Otherwise, the CPU will just be a little more efficient when it is cooler. Stay in boost longer, that sort of thing.

Thing is i feel frustrated i bought this cooler to help me render my projects faster and get better performance from my CPU and unfortunately i didn't get anything more just lost 140$ which is a lot considering where i am from

Just increasing the power limit isn't going to do much. You now need to start tweaking voltages and clock speeds to make gains. Decreasing the voltage to drop internal CPU temps may help here as well.

You should look at some Raptor Lake overclocking guides for further information.

You will be looking at sub 10% improvement in all likelihood. These CPUs are pretty much already overclocked out of the box, which is one of the reasons they demand so much power.

does the cpu still go to 100c?

I wish i didn't bought this cpu😞

A couple related threads have been merged here. Please continue to work the problem in this thread, rather than creating new ones. Thank you.

This is true of most modern CPUs these days. OCing yields far less "oomph" over stock speeds. They are already optimized for excellent performance.

For the OP, what are you rendering and with what applications?
