I have couple of confusions and troubles in my setup with the new system.
The second one here am putting is,
The board is detecting my corsair vengance DDR3 1600 mhz RAM as 1333 mhz.
Why is it ?
if i change it in OC tweaks of the bios menu, is it like OC or just adjusting to what it should be.
Your motherboard's EFI BIOS is not set to use XMP Profiles by default.
You can change the EFI BIOS setting to use the XMP Profile(s) instead of the default JEDEC SPD Timings Table entries. It will then be using the XMP-1600 timings instead of the JEDEC 1333 MHz timings.
