if i try to boot with my 2660 i always geta invalid dimm configuration error, but only if i have 2 of them in there but they will work in solo mode doesnt matter wich one

Have you made sure mounting pressure is appropriate? Bad pin contact could make memory detection wrong.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B


Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.


Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)


How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

Hmmm, I hoped that would have helped you.

Since you say you did have everything working with two other CPU's I assume you do have both 2x4pin CPU power plugged into the motherboard and your RAM has no errors. But can't hurt to check again and run a memtest.


Also if this all turns out into nothing, you maybe want to try your luck over at https://communities.intel.com usually someone from Intel support replies there with helpful information when the first post has a clear problem description and contains sufficient details.
