Anyone here tried running 8 sticks of DDR4 4000MHZ RAM on Evga's X299 FTW-K board? I tried a couple of 8x8GB 4000MHZ kits, and none was stable at 4000MHZ. Raising SA, IO, and Uncore voltages didn't help, I had to drop RAM frequency to 3800MHZ to pass Memtest86.
The kits I tested are rated for 4000MHZ and they worked fine at their XMP settings on Asus's R6EE and Prime Deluxe boards with my 9980XE and 7920X CPUs.
The CPU I tested the FTW-K boar with is 10980XE and I suspect the CPU's IMC may be weak, but until I test with a CPU which can handle 4000MHZ RAM I'd like to hear what others say.

a213m I have found the same issue with X299 FTW-K, and 2 Micro ATX 2 motherboards and THEY FAIL with G.Skill 4000Mhz memory. You have to set them to 3800mhz for stability... I use an Intel 7920x CPU & G.Skill F4-4000C15Q-32GTZR However this memory is not listed in the OVL tested memory. So sad with EVGA, and I know this is not guarantee with this speed, it would work, it a crap shoot. But when you read things on the internet saying its works great you fined out not so much.....  Is not stable with the X299.

Ok, I got good and bad news. After swapping out the CPU for 9980XE from my primary rig I was able to pass Memtest86 with 8 sticks running at 4000MHZ, so the X299 FTW-K motherboard turns out to be fine so far. Looks like the 10980XE I got has a weaker IMC. Oh well, silicon lottery lost.

VCCSA does nothing on X299, and VCCIO is only for Mesh stability. You can run up to +450 mV Uncore Offset to get 4000 MHz. My first 9900X required +450 mV, my second 9900X required +300 mV, and my 10900X requires +250 mV. DR / 2DPC performs 20% better in memory intensive applications like Linpack Xtreme, so 3800 MT/s DR is faster than 4000 MT/s SR.

I was able to get 4000mhz stable on the x299 Dark with my 10900X, I'll try the mV uncore offset on the FTW K and see if that helps.

Aaronr619x You will be a " Super Hero" if you can make it work, I've been told it will not work with your 10900x or my 10920x I have G.Skill 4000Mhz and will not work with FTW-K, best it will do 3800Mhz There has been so many problems with this, like other supporters say..., All motherboard manufactures are worried, about is the next new product to make them more money, and then do it all over again with the next generation....:( They got our "MONEY"

Ok.. I will probably get slammed or called dumn As&&* .... But I have to ask, I have a X299 Micro ATX 2 and a X299 FTW-K motherboard. I an using G.Skill memory G.Skill, Trident Z RGB F4-4000C15Q-32GTZR. I can set his memory on my Micro ATX 2 @ 4000Mhz and it seems to work great. This is using a Intel 7920X CPU or Intel 10920X CPU. But if I install the memory On my X299 FTW-K motherboard I can only use it @ 3800Mhz, when you try 4000Mhz it crashes..... This is using the latest Bio's for each motherboard. "FTW-K (Bios 1.28) & Micro ATX 2 (Bios 1.21)" I know there are different build's on motherboards, but I thought the FTW-K was an upgrade to Micro ATX 2, and just like the X299 Dark was an upgrade to X299 FTW-K, or at least this is what they make it sound like. So I was curios if anyone else ran into this issue? or is there an Technological reason for this issue. Help on this would greatly be appreciated.

Wow, No suggestions....? or Technical Help with this? Would of thought somebody would have had an Idea, or someone with a FTW-K has made this work? Memory @ 4000Mhz

This seems to be a processor by processor issue where the CPU may not be able to handle it.

Thank You for the response, do appreciate it... I am not a computer expert by any means. I have been doing this for as long as my first purchase with an Apple II computer which came out in the 80's, But again not an expert.
My only question is, it works with both processers ( 7920x & 10920x) on the EVGA Micro ATX 2, but does not work on the EVGA FTW-K motherboard ????
Just trying to understand.... is this a bios configuration issue.... or a phenomena....
