Sorry guys. I know what you're thinking, but it won't work that way.
Ok, kinda figured it was a limitation of the chip but wanted an official statement
It is still due to how the traces from the socket are wired, this has nothing to do with the PCIE slots themselves. In BIOS it just controls the pcie lane switches by software and nothing more, it is not adding or deleting lanes just routing them. I think many posters misunderstood what I was talking about before so I wanted to clarify.

Buying new motherboard for Cascade Lake-X is better only if motherboard manufacturer not finished job nice with BIOS.
If they create new BIOS no any reason to people buy new motherboard.
That's point, saving money and enjoy in same performance.
People could freely to use 16-64GB 2666-3200MHz old kits used on Skylake-X and motherboards for Skylake-X.
Every main and widely used memory modules will work nice and improvement in performance will be minimal.
I would never upgrade Rampage VI Extreme to Omega or Encore because Cascade Lake-X.
I would felt bad to spend money. Best experience is when your old X299 Dark from period i7-7820X and old memory kit work with on i9-10920X.
Task of manufacturers is to force customers to spend money as for completely new chipset, socket, new architecture.
Best thing is if you reach AMD performance on your old motherboard and memory,
not to spend 2000$ more and install in carbon steel PC case worth 120$.
Example I would not replace even memory from early days of Haswell-E, 2666MHz 4x4GB not 2.5 years old X299 motherboard.

No one should be using 2666 memory on x299 unless they want 80ns memory latency which when combined with the tiny cache on x299 cpus results in poor performance. Skylake-x lives and dies on fast memory it is more memory sensitive than any other intel platform due to the cache limitations. Skylake-X has nearly half the cache of the equivalent broadwell-e cpus

3200 C14 ram is pretty solid for all current platforms right now, can go up higher like 3600 C16 or 4000 C18 if you want but generally 3200 C14 can OC that manually easily in my experience.

Totally agree and 3200C14 is a far different beast than most of the average C3200C16 kits.

2666 Maybe it's not nicest option for purchase now but could be used if someone have on X299. 2666 C15 is not 80ns Latency, it's 52-57ns. It's not best option but will work. Some people bought 32GB 2666 during 2014/2015... price was over 400$ for some kits. What they need to do, to buy new kit 3200MHz, again 300-350$... Off course not, to continue to use 2666MHz and drop latency and enjoy in X299 + Cascade Lake-X. If someone have money to waste then could buy freely CMD32GX4M4B3600C16, 3600MHz Dominator, Samsung B-Die or CMT32GX4M4K3600C16 same only with RGB... price is only 400-420$ more for memory... 3200 C14 is perfect combination of memory timmings and frequency for X299. Quad Channel and IMC will not allow frequenecies as on Z390.

Show me a one aidabench showing 52ns with 2666c15 on skylake-x physically impossible. DDR4000 @ CAS 16 wont even get you 52ns.. X299 is not X99.. Mesh architecture cannot be compared with ringbus on your Haswell-e cpu which is not memory speed dependent like skylake x cpus are due its fast ringbus.

I have 2 quick questions that may not be answered :( I do own the x299 Dark and shortly the z390 Dark. 1) In the BIOS (Version 1.18 & 1.19) the memory speeds are listed as 3733, 3800, 4000, 4200, 4400. Where is the memory speed for 3866, 4133, & 4266?? To get your memory with these timing to run at this speed you have to OC the FSB :( On the 3866 that is a 102 setting that the CPU/MB sometimes does not like. 2) On OCing memory: () you list running 4133 memory @ 3600. Memory has improved since then and now runs @ 4000 CL 12-12-28-1T, if you have good memory. I have low-end B-Die (G.Skill 3200 14-14-32) that will run 3866 @ 14-14-28-1T 1.6v & 4000 @ 16-16-28-1T 1.6v. I purchased 3 high-end B-Die (Teamgroup 4133 18-18-38) that will only run at the low-end speed. I have scene other submissions on HWBot.org where they have the memory running 3866 @ 12-12/11-12/11-28 1T on a ASUS, MSI, AsRock, Ect Ect x299 MB. How do I get my memory to run at that speed as it does not like to go tighter than the low-end memory??

I mean people buy tens of kits and bin them, that is how they get such high speeds and low CL numbers, the ones I listed in my post most any kit can achieve. I haven't gone too far into memory overclocking since it takes such a long time. I've read some forum posts of people with those Team 4133 kits that they seem to be binned toward the maximum of their capability. I have 4 kits and just run them at XMP setting and they work fine for me. For why some speeds show up and others don't I don't know other than maybe only 100 MHz speeds are supported on X299 ? I haven't seen a 133 MHz memory clock option on any X299 boards I have used but my Z390, Z270 and X99 boards support them.

I might just buy a X299 dark for 10980xe, it's not like this can be a massive April fools joke... Right? Plus EVGA won't make a new dark motherboard for it because, that's just pointless.

I have seen the 133 option. It's been awhile since I have played with the x99 :) The motherboard comes with 3 BIOS chips and not all may be current. I was messing around and tried one of the other BIOS and IIRC it was 1.05. It had many options that where found in the x99 BIOS. Thank You For Your Quick Reply :)
