maxOOOr · Dec 1, 2013

Hi my system is

i7 4770k
Z87 Sabertooth Mobo
16Gb Corsair Dominator Platinum
Geforce GTX 780

It shows that my memory is running at 1333mhz in the bios, please can someone tell me what steps I need to take to get this running correctly at 1866? thanks guys.

enable the XMP profile.

Yeah i've already enables the XMP profile #1 but it hasn't changed a thing :/

Change dram frequency from 1333 to 1866mhz

There should be an option in the advanced section of your BIOS for setting memory speed.
Look on page 3-9 of your MB manual: "memory frequency"

Yeah I change the Dram freq to 1866 then save changes and exit... go back into bios and on main screen is still says 1333Mhz

What does CPU-Z report?

Tradesman1 · Dec 1, 2013

Not sure what you are looking at - may be default boot freq for DRAM - get CPU-Z and look in the memory tab - next to Frequency shoulld show 933 or so since that is true freq and this is DDR (DOUBLE data rate) it will be true freq 933 x2 = 1866 effective

DDR3
16GBites
NB Frequency 3899.1Mhz
Dram Frequency 933.2Mhz :\

maxOOOr :

You double the 933.2MHZ with Double Data Rate memory. So your running at 1866.4MHZ

Tradesman1 · Dec 1, 2013

It's running 1866.4 then - you're good to go

maxOOOr · Dec 1, 2013

Ok cool cheers guys, just a bit worrying when it says 1333Mhz in Bios! stupid computers.

iceclock · Dec 1, 2013

That's fine but 1866 would be sweet
