How do i get full speed out of my memory?

[mohoshin]

As the title states i have my memory working but i noticed it is only running at 1333mhz rather than 1600mhz as it should be.
All the bios settings are on auto timings seem to be correct at the suggested 9-9-9-24.
Can anyone recommend what i need to do on the bios as it seems a little complicated with all the options.

1333MHz is the standard for DDR3 mate.
ANYTHING more than this is basically overclocked (ie. outside the spec of DDR3)

Your RAM is guaranteed stable and fully warrantied at 1600MHz at timings of 9-9-9-24 (More than likely between 1.5 to 1.65 Volts.)

In order for it to run at 1600MHz you need to either:

1) increase your front side Bus (FSB) or BLCK (Base Clock) as its known on intel "i" series chips these days until you see 1600MHz in the BIOS (FSB/BLCK are directly linked to RAM speed - if you move one, the other will move also)

2) use the memory multiplier/ divider in the BIOS to adjust RAM speed INDEPENDANTLY of the FSB/ BLCK.

Systems tend to perform best when RAM is in sync with the FSB/BLCK

Worth noting that Sandybridge chips rely on unlocked multiplier versions ("K" Series) to allow higher overclocks.

Do not increase the BCLK.

For Sandybridge it's set at 100MHz and that clock drives everything in the system, including the CPU cores, the memory controller, PCI Express connectivity, and even Serial ATA and USB controllers.

Changing from 100MHz can destabilise your system.

OcUK also give this warning:

Do not overclock with BCLK, doing so could limit lifespan of the CPU

Go into the BIOS and change the System Memory Multiplier so that the Memory Frequency is 1600MHz.
