OC tips for i9-14900KF on ROG MAXIMUS Z690 EXTREME GLACIAL

[Hin]

I continued reading news about the OC on i9-14900KF and following the line of CS2 I found this on Geeknetic

They manage to put an Intel Core i9-14900KF at 8 GHz and reach 1300 FPS in Counter Strike 2

at the end of the article they comment this:

[...] the high-efficiency cores of this Intel Core i9-14900KF were disabled, and the frequency of the high-performance cores was increased to 8 GHz. With this Intel has managed to demonstrate that the new processors, in addition to reaching 6 GHz from the factory, are also capable of reaching higher clock frequencies given their overclocking capability.

What do you think? is it a necessary requirement to disable this?

P.D.: I had another link around here about the difference in performance in programs/games, but right now I have lost it...

Hello! How exciting to hear about your overclocking journey and your new setup. The i9-14900KF is a real beast, and with that motherboard and RAM at 6000MHz, you're sure to push the limits. I'd love to see how you do with overclocking! Do you have any specific goals in mind for performance? I'm here to exchange tips and experiences. Keep sharing your progress!

Hello @brendag

Well, as I have already mentioned, there is no OC target like the one that can be seen in the news (8GHz or 9Ghz), it's just that I have been linked to HL for many years and I am interested in doing OC to improve performance.

The main idea is to gather info and share the process of what can be achieved at the user level, and especially now I am very interested in seeing how much of the performance issues are true and how they are being solved.

I have been reading these days and I have found a solution to 3 of the 4 usual failures in the latest gen, I will put the link in another post to give my opinion on this.

Possibly ASUS has already applied all these solutions so far and is working on the next one, which is why perhaps the issue of temperatures is more limited when it comes to Bench and Gaming

I leave you the news I mentioned above

Intel has found the cause of the instability of its Core chips of the 13th and 14th generation. This is the solution it proposes to us

What do you think?

Well, it seems that in single-thread it is lowering the performance by 5-7% with that new microcode, and they promised that the performance would not be affected...

[Hin]

@krampak Well we'll see/check it soon since shortly after posting (yesterday 03.10.24) searching, we have news of microcode 0x12B from ASUS

Yesterday they published on geeknetic.es

ASUS launches beta BIOS with microcode 0X12B for Raptor Lake

For now it's a BETA, let's see what happens...

more news, related to what was said by @krampak

Intel solves the problem of high voltage of the Core 13 and Core 14 when idle with microcode 0x12B

Intel lied: microcode 0x12B for Core 13 and Core 14 reduces their performance

I update the thread

I keep tinkering with the Bios parameters to get the most performance out of it (I haven't touched the multipliers yet and I'm still around 5720 MHz), to be honest, if I didn't notice the micro temperature issues before, it seems that with the beta update that Asus released, this issue is no longer a problem, the temperature is always stable.

With the latest changes, I've increased the multi-thread ranking performance to 1817876, with improved results in the tests

Result in AVX2 mode

What I can't manage to do is improve single-thread performance, I don't know if it's due to fatigue, but the results have dropped from 141069 to 131400, I don't know if it's something noticeable or if it's related to having synchronized the cores.

I'll have to read about it, but if anyone can give their opinion, it would be appreciated so that I can continue to improve.

Regards

Well, from the test bench's point of view, it seems that both tests (the one from October and the one from today) have been executed under the same conditions: PC without background loads, same memory configuration and same version of Windows 10.

In summary, the single-thread results are comparable. And indeed, there has been a 6-7% drop in performance.

The only relevant thing that changes is the BIOS version: 3802 from August vs 3901 from September. On the Asus website is the version 4001 from October where the issue of voltages is solved. Without being an expert in the stability and reliability problems that have been with these micros, my recommendation is that you update as soon as possible.

@cobito Many thanks for the appreciation, with all the daily routine of returning to work in the last quarter I had not noticed to look at new bios and I had not skipped the notice about this new version of bios, so I continued with the Beta that was released which initially solved the problem 0x12B

Precisely now that you have commented on that % of performance, I scrolled up because the figure sounded familiar to me and in our thread, @krampak already mentioned that same margin of performance drop, so we confirmed firsthand that it is a fact https://foro.hardlimit.com/post/543813

I will update as soon as I can to see if there are improvements and it is fixed
