Why is my RAM underclocked??

Question

I am using Piriform 'Speccy'. A utility that reports on system configuration and performance. It reports that the RAM is ' 8.0GB Dual-Channel DDR3 @ 664MHz 9-9-9-24' I ordered and paid for 8GB DDR3 SDRAM @1333MHz - 4x2GB. I would love an explanation if someone has any ideas about what is going on. Thanks. Jeff

You are running the RAM you purchased. DDR3 SDRAM PC3-10600 @1333MHz.

DDR3 SDRAM is double-data rate three synchronous dyamic random access memory. You can read more about it here. Look under Modules and compare what CPU-Z shows with the table for DDR3-1333.

DDR stands for double data rate. The actual speed of of your memory would be ~666MHz but it is quoted as 1333MHz when you double (double data rate) the speed.
