im even considering buying some new ram. Im positive this ram is good so im unsure if its legitimately an issue due to not being from the same "kit" an issue due to being on the QVL as 2 sticks but not 4, or an issue due to the IMC.
or something else alltogether.
edit: looked into it more, i dont think the QVL has jack-all to do with it. Also ran thaiphoon against them and it looks like theyre 100% the same except for one kit uses a different thermal sensor. both are samsung b-die, same part # etc.
Just wrote an image to an internal with 2 sticks in. verified it. good. added 2 more sticks, tried to verify - nooo buennooooo.
Dont know what to think. Even if it were the IMC, or the ram, why is it that writing to a usb hard drive is perfectly fine, whereas an internal, ANY internal (i have 6 to choose from, and i tried every solitary one) all fail.
I ran into something similar, was running 2 separate kits at 3900mhz for months, good VCCIO/VCCSA voltages etc, then would get random memory related BSODs, finally was only stable with 2 sticks, then even after replacing RAM with a QVL kit I still had issues, had to RMA my 9900k, been stable since, even considering returning my new ram and just run the old kits (4266mhz CL19 at 4000 CL16).
Can you please fill in your pc profile so that we know exactly what parts you are using.
Also what version of windows and what BIOS you are on.
