Corsair DDR3 Vengeance Pro 2400MHz showing up as 1333MHz?

[crapazilla]

Hi,

I have the following system:

Asus Z97 Pro Gamer mobo
i7-4790K CPU
2 x Corsair DDR3 Vengeance Pro Gold PC3-19200 (2400) 8GB RAM

On powering on, the system shows I have 16GB 1333MHz RAM rather than 2400MHz. Is there a BIOS setting I need to change or could the RAM or mobo be faulty? It does this whether the sticks are in a pair or individually.

Yes, you need to enable XMP int he BIOS.

Yep just like tiny voices said. Just go into the BIOS and enable the XMP profile, if your BIOS layout is similar to mine, you should have the option in the user friendly part of the bios, not the advanced part (you can do it in both, but the user friendly one will be easier).

Thanks guys. Why does it default to 1333MHz?

Thanks guys. Why does it default to 1333MHz?

Because technically, 1601mhz and above is still an overclock. So just in case you have stability issues it defaults to 1333mhz until the user decides to change the speed.
