I have a screenshot of the RAM section in CPU-Z but i don't know how to show it to you guys. Basically it says: DRAM Frequency 668.5Mhz. While the ram i have is supposed to run at 1866Mhz. I don't know, any ideas/solutions if there is any?
 
ddr ram is double data rate, so the 667 is doubled to 1333mhz meaning that is what your ram is running at. Just because your RAM is 1866, your cpu and motherboard also ahve to support that speed first, and second, you need to go into the BIOS and set the 1866 speed manually.
 


I have an Asus P8Z77-I Deluxe Motherboard and an i7 2600k CPU, it should support the RAM i have.
 


Then you need to go into your BIOS and enable XMP profles for the RAM and select 1866.
 


Just did, the DRAM Frequency is now at 938Mhz. That should be 1876Mhz which is fine i guess?
