Intel X79 Quad Channel Memory Guide
By Jake Crimmins posted Dec 07th 2011
Intel® has made several changes when it comes to memory for the new 2nd generation Intel Core™ i7 processors (Sandy Bridge-E). Corsair has launched new Quad Channel DDR3 memory kits specifically designed for Intel’s new X79 motherboards. Intel has added the ability to run quad channel with up to eight DIMMs for a total of 64GB of memory. All the Corsair memory upgrade kits designed for X79 feature four modules and support XMP Profile 1.3.
Intel also added native support of 1600MHz memory modules and a 2400MHz memory divider. This means that every Sandy Bridge-E CPU can run memory at 1600MHz. Not every CPU can run the memory over 1600MHz, but with mine I was able to hit nearly 2600MHz. The 2400MHz divider is geared towards overclockers and enthusiasts and allows them to run our CMGTX8 memory modules without changing the base clock frequency.
If you are unsure of which kit is for you, we have put together a Memory Buyer’s Guide below.
You can also see what memory is compatible with your motherboard by using our memory finder. An example from our memory finder is shown below:
