What are the Intel® Core™ i7 Extreme Edition processor DDR3 memory voltage limitations?
Intel recommends using memory that adheres to the Jedec memory specification for DDR3 memory which is 1.5 volts, plus or minus 5%. Anything over this voltage can either damage the processor or significantly reduce the processor life span. back to top
What is the maximum frequency for DDR3 memory when used with Intel® Core™ i7 Extreme Edition processors?
Intel® Core™ i7--9xx Extreme Edition processor series support up to three channels of DDR3 memory with a maximum frequency of 1066 MHz. Intel® Core™ i7--3xxx Extreme Edition processor series support up to four channels of DDR3 memory with a maximum frequency of 1600 MHz. If faster DDR3 memory is used, it will be down-clocked to operate at 1066 MHz.

Are there any new chassis requirements for the Intel® Core™ i7 Extreme Edition processor platforms?
There are no new chassis requirements for the Intel® Core™ i7 Extreme Edition desktop platforms utilizing the LGA1366 socket. Currently available chassis tested to support 130W processors should meet the requirement. See the Intel® tested chassis list at www.intel.com/go/chassis for a list of chassis that will work. The use of a Thermally Advantaged Chassis (TAC) is still highly recommended. back to top
Does the Intel® Core™ i7 Extreme Edition desktop processor support Error Correction Code (ECC) memory?
The Intel® Core™ i7 Extreme Edition desktop processors and desktop boards that support these processors typically do not support ECC memory. ECC memory is usually used on servers and workstations, rather than on desktop platforms. This is mainly due to the price premium of ECC memory. Check with your desktop board manufacturer to see if ECC memory is enabled on your board. back to top
