My motherboard is MSI Z87-G43,
I have installed two Corsair Venegence RAM CMZ4GX3M1A1600C9 in slots 2 and 3. The system only shows clock speed of 1333Mhz during boot. why is it so?? should it not be 1600Mhz?
 
Solution
Yes, 'technically' it is overclocked to 1600 from 1333, but using the XMP profile is not the same as overclocking, just getting your memory to run at the right timings etc. You can get memory that is 1600 at SPD setting, but you will pay more (and you can overclock it more), but by and large, it does not really matter, and using the RAM at 1600 in XMP is not going to stress the system.

You need to press 'delete' key as you are booting up and it will take you to the BIOS screen. You are looking for the OC page. If you have a manual, it is Section 3 page 19. If you do not have the manual, you can download it from MSI here:

With memory, the SPD speed can be lower than the tested speed, see here for your RAM:

http://www.corsair.com/memory-by-product-family/vengeance/vengeance-4gb-single-module-ddr3-memory-kit-cmz4gx3m1a1600c9.html

It gives it as being 1600 under the XMP profile, but you may find that your latency under 1600 may be lower than 9-9-9-24 (I have Corsair RAM which does this). You could overclock beyond 1600, but I would leave it at this, in case it becomes unstable. Also, I looked at your first post again. Put your RAM in slots 2 & 4, not 2 & 3, for dual channel.

Yes I have changed it to 2 n 4 after seeing on the manual. on enabling xmp profile it has gone to 1600Mhz.
am i already overclocking the system by enabling xmp profile?
