Quad channel not working

Ffffddddqhssb · July 29, 2020

Hi!

I have finished testing my new computer and quad channel seems to not be working. When I put my ramsticks in DIMM 1,3 and 7,5 my pc turns on, but does not post, neither my peripherals light up. But when I put only 2 ramstocks in 5 and 7 everything works fine. I hav tested ramsticks indivodually and all of them work. I have crucial ballistix 4x4 memory. I have Msi gaming 9 ack x99 board and a xeon 2640v3. Motherboard had two twisted pins when i got it, but I was able to straighten them. I have also read that there particullar ramsticks have some issues regarding quad channel but I duobt that its the memorys' fault.

Does anybody have an idea of what could be the problem and how to fix it? Can it be the bios or maybe latency or frequency of the ram?

Thanks!

Also, if I put the ramsticks in 2,4,5,7 my pc goes into a loop.

Also, there is a code 19 when I boot with 4 sticks in quad channel.

I'd update the BIOS if it is an older version. If that isn't an option or doesn't fix it, I would test the RAM using memtest86 or something like it to see if it is faulty.

I remember x99 having some ram challenges, especially on the early bios.
