Hello everyone,
Before I begin, I would first like to say that I did search the forums and could not find an exact response to my problem. I cannot get my RAM to operate at the correct speed or even the maximum speed listed in the specifications for my CPU.
Here is a snapshot of the memory tab on CPU-Z: Memory.jpg
Here is a list of my components:
i7-4770k
ASUS Z87 Deluxe
32 GB (4 x 8GB) G.Skill 2133 MHz RAM
2GB EVGA GTX 670 FTW edition
1 TB Samsung 850 EVO SSD
There are 2 XMP profiles listed in the BIOS and they both list the correct RAM information, speed, and timings, but neither of them go above 1066 MHz (as indicated by CPU-Z.) I know that Intel states that the memory specifications for the i7-4770k are 1333/1600, but I'm not even getting that. I don't know if this matters, but there is a SPD tab on CPU-Z (I have no idea what it's for.) On that tab it says 'Memory Slot Selection' and 'Timings Table'. Under Memory Slot Selection, all 4 of my memory sticks say the max bandwidth is 667 MHz. Under the Timings Table, it shows 4 columns (presumably 1 for each stick of RAM) and only 2 of them are using the XMP profile and are set to 1066 MHz and the other 2 are using JEDEC and are limited to 667 MHz.

Someone on another forum stated that if you OC the processor and push the RAM voltage to 1.6 - 1.65, you can get it to run at 2133 MHz. I have my i7 overclocked to 4.3 GHz and the XMP profiles show 1.6 volts for the RAM, but I'm still only getting 1066 MHz. The motherboard supports up to 3000 MHz, so I don't understand what I'm doing wrong.
I know this is a long post, but if someone can help me, I would be forever grateful!
