Coming from a binned and delidded 8700k I played about with plenty of overclocking in my time with it. Now I have a 12700kf and it feels like I know nothing.

I set XMP in the bios and fired up windows did some stressing while looking at HWmonitor and I see cores only boosting to 4700mhz not the 4900/5g advertised. Jump back in the bios there's default profiles such as gaming and max performance which give 4.8g - don't like the idea of using these anyway. I enabled Multi core enhancement and lone behold I get 5g on all performance cores but at the cost of some nutty 1.41volts.

So questions: without overclocking how do I get my CPU to boost to it's advertised clocks

What are these memory gears, never heard of them before does this replace XMP or can I run both.

Where's load line calibration these days? Is it done away with?

When overclocking should I just start with 5g on all Pcores at 1.3v and see how I get on.

Using a z690 Gigabyte Gaming X MB with a H150i LCD AIO 360mm BTW.
 
OK been playing all day and answered most of my own questions, the last one I have outstanding is trying to set all cores to 5 or 5.1g. When I do this I have 2 cores hitting 5 or 5.1g but the rest still sit at 4.9g, is this normal behaviour? Anyway round it or is it boost 2.0 limiting me
 
Yes they are all sync'd to 5g, after looking a bit deeper I'm getting a solid 5g in normal work loads and cinebench, soon as I run Prime95 or OCCT I get scores dropping to 4.9. No AVX offset is set though.
Volts at 1.3v and temps high 50s
 
XTU - Normal CPU stress is fine staying at set 5g OC, AVX or AVX 2 though same thing hitting 4.9 on most cores.
Deffo AVX related but how is it getting by when I've set it to 0, bizarre.
 
Yes Cinebench shows all cores working away at the set overclock even though this uses AVX, as does the overlay when gaming. It's prime95 and OCCT etc that triggers it.

Done some more playing and even with the AVX offset set at 0 in the bios if I flick Intels extreme overclocking software to include an offset of say -2 then I put it back to 0 again this appears to set it fine from this point onwards and fix the problem. I'm guessing it's a bios update for the board needed as it appears to ignore my AVX offset at times.
I've searched the internet and appear to be the only person with this issue, or the only one that's noticed it so far.

I found LLC in the end, it was just hiding.
 
Yeah to say I'm running them at the same speed of 5g on all cores, I have noticed a considerable bump in performance, obviously I have more cores and threads now but it runs much cooler, BF 2042 see's mid 40c's and none AVX stressing mid 60c's. I got a nice 20fps jump also in BF2042, CPU usage while fine on the 8700k ran between 60-80%, it's not down to 25% on the 12700kf :)
 
8th Gen there was loads of guides flying around with secret little settings to tweak, hardly anything on this gen. I struggle to get anything more than 5g (allcore) out of mine which is nice and stable at 1.28v but soon as I move to 5.1 I can't get it 100% with 1.350 so going to leave it there I think
 
I've tried 5.1 I can get past 10 loops for cinebench but get a crash in OCCT

I'd like to know what Gear 1 and Gear 2 do on the memory, I've done some googling but soon as I use gear 1 I'm pulling the battery on the board to try and get it boot again.
