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.

    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.

    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....:(
