Lower geekbench with higher memory clock and vice versa?

[Ed Ding]

Hi

Just finished Ocing my [email protected], ga z170x gaming 5, 32GB of ballistix sport 16-16-16-39 PC-19200 RAM.
Ram run @2400MHz
Geekbench is
5821 // 19079

When I enter 2900mhz as ram speed in bios it still boots fine but geekbench drops to
5400 // 15000

What's happening? Any way to make it right? Thanks

What do you mean by that? I increased the ram voltage to 1.35v...
