ASRock P55 Deluxe BIOS 2.10 (latest)
i5 750
F3-14900CL9-4GBSR

Only 2 slots possible for memory - cooler blocks the others.

just installed F3-14900CL9-4GBSR 2x4g kit.

I get blue screens if I use XMP #2. (1866) seems to set things too high, I think BCLK 187?

Possible a ddr3-1600 kit that would work with XMP settings with this board?

Really need the sticks in slots 2 & 4 (or even 1 & 3) for dual channel and XMP to work correctly. Can try using 3/4 and manually setting the timings and OC

[mrboonmee]

Yes they are in 2 and 4, only slot 1 is not usable.

May try a manual config, g.skill just sent me something on that.

may want to go 1600 speed memory.

May need to raise the VTT voltage a little from what XMP would set it to.
