What does overclocking memory do? - Page 2

post #11 of 14
Just FYI, your memory is very dependent on your CPU, so all else being the same I'd take a 4.8Ghz CPU OC with DDR3-2133 (9-11-10-27) over 4.2Ghz CPU and DDR3-2400/2600...

^ Correct. No CPU OC, no gain. CPUs are designed for standard memory, DDR3-1600, so if you plan to utilize the performance of high frequency RAM, you better plan to OC CPU and NB, otherwise you will notice no significant difference.

This is not mentioned in those articles, so they have confused many readers. Of course a higher frequency can produce a higher bandwidth/throughput, otherwise why the heck are companies selling higher frequency RAM rather than lower timing RAM? How the heck are companies like G.Skill breaking world records if DDR3-1600 is the fastest? Common sense. rolleyes.gif

Happy clocking!

Cheers

Haha that's exactly what I am running but 5ghz 3930k with gskill 2133 9-11-10-27 I can go a little higher in memory but with looser timings I find the 2133mhz at 1.652 volts to be the sweet spot. :/)
