From what I understand form the available material, U.2 (PU1) and U.2 (PU2) can be populated without affecting the above PE1,2,4,6 availability/lanes?

I'm guessing you're talking about the x299 dark board? If so, it would seem one of the slots wouldn't work when using a 44 lane skylake-x cpu as both pu1 and pu2 pull x4 lanes from the cpu itself according to the manual. With pe1, pe2, pe4 & pe6 populated you would be using 40 pci-e lanes from the cpu leaving only 4 available for only one of the pu slots to work. With a Cascade Lake-X 48 lane cpu both pu slots should work in theory as 8 pci-e lanes would still would be available.

PCIe mapping found in this:  https://xdevs.com/guide/e299ocg/

Oops, yup. X299 Dark. Sajin, your psychic powers are at full strength.
Cool GTX - Thanks for the xDevs link, that's a new source of X299 Dark info for me.
Given the existing details I'm surprised they haven't commented on Cascade Lake-X PCIe mapping, particularly as the i9-10XXX processors are identified earlier in the page.
Nevermind, Nothing ventured, nothing gained. Once I have proof of concept with my PSUs (2 x AX1600i) I'll give the U.2 NVMe storage a crack.
 
Thanks again.

 
Send a PM to TiN_EE --- he might know a thing or two about it [he was part of the EVGA development Team of the MB an is the author of the xDevs]
 
Point him at this Thread so his comments can be seen by all members of the Forums

Which CPU are you using?  Still the i9 7920X?
 
What utility are you using to read the PCIe lanes?

There is no any difference between SKX 44-lane and CLX 48-lane CPUs in PCIe mapping on X299 DARK.
Motherboard does not use (pins are physically not routed to anything) those additional 4 lanes on CLX.
So everything is exactly the same as SKX 44-lane maps.

And yet Intel processors haven’t changed much.

My board didn't come with the latest BIOS pre-flashed, but it still recognized 10980XE.
 
Contact EVGA with your board's serial number and they'll tell you if it supports CL-X out of the box, and if it doesn't, they will send you a new BIOS chip with the latest BIOS flashed.

Thank you for the information, it helps a lot

 
I need to change. where to buy? allien xpress china?

Does anybody know if theyre worth it

Anyone know if the x299 dark, with i9-10900x cpu, will support 4 32gb simms for 128gb ram?  Documentation suggests not but seems to have been written long before release of this cpu.  Intel's documentation suggests support for 256gb ram.  Not a big deal: 64 is working fine for now, but I use vms a lot and might want to max out the ram eventually if possible.

TiN's old post here says since 1.19 bios the X299 Dark has enabled 32GB dimms.  https://forums.evga.com/3...erboards-m3010100.aspx

Thanks!

I know this is an older discussion, but anyone know where I can get the X299 micro I/O shield? No response from EVGA so far

Thanks...but have been doing that and so far have nothing. Seen some others but not for this board.

Hi
Yep as first stated , first asked EVGA and so far no response. Possibly because is an older board.
As for the blanks, thot about that but with my skillset these days....let's just say it would not be pretty and more of a mess.
Thks for replying.
 

Apologies for the delay in updating. Work, life, kids, etc.

Mobo didn't post right away, and it took my tired brain a moment to realize I had all 4x32gb in onboard, and it wasn't gonna like that. Went down to one stick, and it posted right away after a cmos clear.
Mobo came with 1.20 installed, so it recognized my 10980xe instantly. So sorry I can't confirm if it would work for people with older BIOS versions. BUT I got this from the EVGA store on Amazon, so I have to think that if I got it with 1.20 in 2023, you'd be hard pressed to find one with an earlier bios.
Flashed up to 1.29, and installed all 4x32gb cards of ram, no problem. Went with corsair on this one, the vengeance line has always worked for me. Didn't feel like paying for really high speed ram, so I went with 3200, and I still managed to OC to 3800 no problem.

I think I remember seeing on a GamersNexus extras video recently that the OC AI for x299 was the first EVGA did. That said, its pretty simple click and go. It's suggested 5400ghz was a little too aggressive and I hand to cmos clear again. But the conservative setting put me at 4.8ghz, and i'm running stable. Currently using an AIO, and plan to go duel loop, full liquid next year sometime, with an all black build in keeping with the dark theme. Maybe even a soft tube build. Who knows.

Anyways, highly impressed with the board. Tin and Kingpin did amazing work, and their documentation was impeccable. It's a crying shame EVGA isn't making cards anymore, and I really wish you all would consider doing the investment to develop your own GPU cores or work with Intel or something. I'm really worried your Mobo's and PSU's will go the way of the dodo too, and that would be an equal shame.
