ASRock Z77 Extreme4 With G.Skill 2133 RAM

I'm having trouble getting my motherboard to run my RAM at the appropriate frequency.

I've tried changing the timing manually and have set the profile to run at 2133, but when I boot into Windows and check CPU-Z it keeps telling me that the RAM is still running at 1600.

Any tips or tricks with this BIOS to getting this to run?

I've got the timing set to 10-12-12-31 and 2N.

CPU is an i7 3770k.

Thanks!

Do you have the latest BIOS? What st of sticks the model # please. May need a slight increase of the CPUVTT voltage (MC (memory controller) voltage)

I just flashed the most recent BIOS (Version 2.90). I thought that was going to be the case because it mentioned something about not being able to run a similar RAM stick at 2133.

These are the sticks of RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I'm going to take a picture of the DRAM config page and report back.

I've included pictures of the BIOS page with stuff that concerns the RAM. Hopefully this helps.

And finally, CPUZ telling me that my RAM isn't running in 2133.

Are you looking in the memory tab of CPU-Z - if so in freq it should show 1066 - 1066 x 2 = 2133 effective since this is DDR (DOUBLE DATA RATE) -

Interesting... it is showing 1066.5 on the DRAM Frequency. So I guess it is running at 2133. Then how come when you look at the RAM individually the max bandwidth is still showing only PC3-12800 instead of the PC3-17000?

Look at the DRAM tab, not SPD.

It will show ~1067MHz, which is DDR3-2133

DDR is double data rate, so double the MHz gives you the effective DDR3 speed.

As long as XMP is enabled, everything will run accordingly so don't worry!

The SPD tab shows you standard values, not what the memory is actually operating at. The "Maximum Bandwidth" is highest value for the RAM with AUTO default settings. Since you are using XMP, that value does not matter at all because standard value is no longer used or relevant.

Enjoy!

Thank you

I'll read that, thanks for the additional info. :)  I've marked one of your responses as a solution.
