Intel Core i9-12900F: has anyone tried it?

[Gatt]

Looks like I'm the only one around to have assembled a new rig around it. Well, my ASRock Z690 Taichi has some weird PL1 and PL2 default settings (last bios 7.02): 4.096 for both. If I'm not wrong this means "no limits".

As usual I've tested the new assembled PC with Cinebench 23 to check temperatures and stability and, understandably, with those PL1 and PL2 values, CPU temperatures went sky high: 90-92°C. The result for multi thread test was very good (around 26.500) but those temperatures not.

I have found an online a table with some Intel preliminary values for non-K CPUs and for the i9-12900F it shows 65W for PL1 and 202W for PL2. I guess I should stick with these values. Any thought?

Thaks for any help.

You of course read this PL for 12900 tested before you started this post?

You mean if I read those default PL1-PL2 values before testing? The answer is no. Usually ASRock MBs have AUTO default values on almost every value. To find "no limit" default values on such sensitive parameters was a big surprise. I usually choose non-K CPUs becouse I dont care about OC and want good performances without cooling/temperature problems.

No. He meant to ask did you read this article ->

Intel Core i9-12900K Alder Lake Tested at Power Limits between 50 W and 241 W​

It will help you decide what PL1 / PL2 values to choose for your system.

If you don't want to put effort in reading the article, set PL1 = PL2 = 150 and you should be set. If you find 150 is comfortable and your cooling system can take more, set PL1 = PL2 = 180.

Ah OK thanks, Yes I read it.

It seems that the article is mainly for K CPUs, the 12900K in particular. There is a link to the 10900 test but nothing about the 12900.

P.S.: however the last part of the conclusion is VERY interesting. Thanks.

Why does the CPU being a K CPU matter? W1zzard didn't touch the CPU multiplier. He only changed the PL1/PL2 values. W1zzard said and I quote:

Just like on previous Intel CPUs, the PL1 and PL2 values are fully adjustable even on non-K SKUs. In this article, we test a Core i9-12900K processor with various power limits ranging between 50 W to 241 W, which include 75 W, 100 W, and 125 W. We're also including 190 W, which is the rumored power limit setting of the upcoming non-K Alder Lake processors. All these results are compared with an untouched stock Core i9-12900K and various other processors across a big selection of our processor test bench.

Understood, thank you.

I'm amused by how the 12900k @ 50W might not beat a 4770K in 720p.
