[SOLVED] Some dimm slots not working with bios modding.

[Kigetsu]

I decided to try inserting a coffee lake processor of 1151v2 socket into socket 1151v1. Found some information about it (like pinmod, how to moddify bios and some more). After i did all right i first tried to boot up, but i could'nt do it with dual channel memory. The only way it boots up is when i have 2 sticks in single channel closer to processor and when i have 1 stick in 2nd slot.
But when i go back to my older processor i5-7500, the dual channel works just fine. Who know how to fix it? pins in socket is in ideal condition and i reset cmos before putting an processor.

Specs:
i5-9400f
gigabyte b250-fintech
2x8gb hyperx fury 2400
Im on the latest version of bios.

It would appear you did not perform this so called "pin mod" properly.
