more voltage on X3I is also needed with Round Trip Latency disabled. Seems more like the X bios are tuned for different terminations (sub zero). Like I also can't boot 6666 on X3I unless I'm exactly at VDD2 1.35, 1.325 doesn't work, 1.375 doesn't work. So also looks like very specific requirements in bios.
F6d 6800 doesn't care as long as it's high enough, 1.45 VDD2 no problem.
I also think my particular retail Tachyon is not great. Every time I tried your profiles/settings before, it didn't work on my board, so thanks, but let's not do that again

Any ETA on when RTL tuning will come to official bios?
With X3I my CPU and DIMMs do 6666 30-39 2T stable with RTLs 62/57/63/57 -> 13.8k GB3 mem
With F6d, I can go higher to 6800 32-41 2T stable and 100 mV less VDD/VDDQ, but without "Round Trip Latency" RTLs end up at 70/68/69/66 -> 13.0k GB3 mem
Both is kinda meh imo

So what's the best bios for memory OC with 12900K (not S) and which GTL version goes with it?
Should I just grab the latest version (lowest down link in OP) each? -
So then this stage implies "all P cores enabled" because there is no 12900K(2P)? or is it allowed to set the CPU to G7400 so the calculation is actually done based on 2 P cores enabled?
-
also why is the score always getting devided by 8, no matter how many cores are enabled? shouldn't it be 16 then for the 12900K?!
-
any ideas what's causing the xtu monitoring to be off by several hundred MHz im my case?

Three months in between, but the review was published later. Also, it looks to me like bios version X2g was used in both.
Honestly I can't say for sure anymore as this was quite some time ago. It's possible that I made an error there, that the board was capable pf running 3866 devider with one of the bios versions current at the time and I might have done my final round of testing on the other bios (must have been F5 iirc). So if you're looking for an error in my testing, I can't prove the contrary.
Though I don't think it would chang much regarding the overall conclusion. And having to hop between bios versions for gear 1 or gear 2 optimizations also wouldn't help much either frankly.

"DDR4-3866 im Gear 1 war schlichtweg unmöglich. Egal ob dual-ranked oder single-ranked DIMMs, egal wie viel SA und IO2 Spannung..."
???
3 months between those screenshots and the review and a lot of bios versions. review was done with latest available at the time, which could not do 3866 divider

Picked up my Unify ITX last week - latest bios 126 has no support for non-K OC, at least on a C0 stepping 12400f.
@skullbringer @Birilio Apologies for the @ from a random, but have either of you seen any sign of a C0 stepping non-K OC bios for the ITX board?
sadly no, also don't have eta. but you can mod the microcode from ux a22tc into 126, same worked for h

Will testing today later, but usually I start with lower BCLK and go up in OS and don’t down ?.
for example start with 180 BCLK and goes up to 190. from 190 I can go down but not tested to go under 180
you also can't set it down via gtl, though you can set it up.
sure, you don't need bclk minus often, but when you needed it's usually in a situation where it's really annoying if it doesn't work

I think radio buttons are also buggy with this bios version, you can go up bclk with +, but not down with -
in Germany we call this an Einbahnstraße

here's bios a22 releases for unify-x for specific cpu steppings. first bios versions that support non-k cpu oc at least from my testing
C is for C0 stepping CPUs, H for H0 stepping
proof, running i3-12100F in p95 small fft at 5.2+ GHz:

it boots 6800 in 1 of 30 tries, so i'd rather keep this memory training state then instead of having to do another 30 post loops each time I crash ?
-
did some benching last night as well on x2i, it once trained 6800 with tight rtl's and was gb3 stable, then never trained 6800 again. also had to do a few power offs and clear cmos to recover from 28 - 54 loops... is sa locked on non-k chips btw?
on the filp side, once it had trained at reasonable speed and timings, doing the bclk oc was really easy and straight-forward. also gtl for cache and p core multi worked great!

thanks for sharing the new bios! it can't do 1T yet, can it?
i've tried it a few times and always get straight 28->54 -

1T and AVX512 will come. The last bios I tested supports AVX512, but causes some problems, so it's not online yet.
As soon as I have a working version I will upload it here.
Cheers, thanks for the update!
-
anyone know eta on command rate, rtl and avx512 settings? last bios updates are almost 1 month old

the former ;) https://www.overclock.net/threads/overclocking-10900k-results-bins-and-discussion.1748256/post-28535774

Here's some screenies for you.
3866x102, 1.65 SA, 1.6 IO 2/Mem, 1.9 Vdimm, 0.9 VTTDDR.
Forcing a memory retrain by going to limp mode and then F10 without any changes, gives me either of the two sets of RTLs, but never anything in between.

Holy shit, GTL is easy to use and works so well, thx for linking!
On another note, has anyone manged to reliably and consistently train RTLs on the Tachyon? On 2Xg it keeps flapping for me between 68-67 and 55-56 from training to training, which looks like opportunistic Round Trip Latency disable or enable, like you can manually set on Asus, but I haven't found such setting in the Tachyon bios yet.
When I manually set them to either of the auto combinations above, it only trains successfully in about 1/10 attempts, otherwise fails (55) and enters recovery mode

Are you running cml or rkl? I have gotten up to 4800cl14 on DR b-die into OS on cml. Rkl doesnt seem as capable with DR.
yeah rkl, sorry should have mentioned.
think the m13a does a lot better, but the m12a doesn't seem to have that optimization yet for dr b-die.
-
Has anyone managed to get DR B-Die Running above DDR4-4400 on the M12A?
Seems like I am hitting a hard wall there, no matter which bios version or settings

nice score [:Y:] high frequency djr really likes to nuke OS installs :P

why is a xtu sub getting removed for clock shown in cpu-z?
firstly cpu-z clock is not part of the "limitations/rules", secondly cpu-z can't monitor max clock, only current and thirdly that's only recorded at time of the screenshot and not the benchmark, so that makes no sense threefold...
