How to set stable 2400 mhz ram?

[Airbender_Aang]

I have a hard time setting my rams up.
I play Dota 2 and after some time the game freezes to desktop without any message. Just simply leaves the game.

asrock fm2a75 pro4
a105800k
hyperx savage ddr3 2400 2x4 gb

what should I set in bios. It is stable on 2133 and it was stable on 2400 on my previous mobo (asus f2a55m le)

If your motherboard bios supports XMP settings use that to get to 2400 speed.
Actually, I think the difference will not be noticeable.

It is actually noticable. In idle 110 vs 120 fps
in fights 70-80 vs 50-60.
xmp is not stable.
The question is, what clocks and/or voltages should I bump up?

See if there is a bios update that addresses the issue.
XMP is a set of ram settings imbedded in the ram itself.
It should make no difference if you set those parameters yourself or let the motherboard extract those settings from a XMP profile.

Run cpu-Z
The spd tab will show you several sets of settings that should work.

I guess the problem isnt about the timings, I think the XMP does not set things like NB voltage and clock.

What voltages should I set higher?
