I must be misunderstanding what DDR3 1866 is? - Page 2

post #11 of 15

Anything over 1600 is considered "overclocked" you'll need to enable an XMP Profile to get your RAM running at it's rated speed.

 

Now, the sole purpose of high speed RAM is mostly RAM Disks, Folding, or Benching. (Correct me if I missed something.) but you will not notice a difference in everyday use or gaming. Or just for the e-peen. :P

MHz when talking about DDR speeds is a misnomer.

No part of DDR3-1600 (for example) runs at 1600MHz. MT/s (million transfers per second) is technically what should be used.

no.

its not 1600mhz.

anything over 1333 is an overclock, as 99% of ddr3 chips are originally rated for 1333.

thank you god someone was listening in computer school.

So are you telling me I wasted my money buying this for my new build?http://www.newegg.com/Product/Product.aspx?Item=N82E16820104288

You're just being a bit pedantic there. In common parlance it's 1333MHz, 1600MHz, 1866MHz, 2133MHz, etc. RAM even though it's technically MT/s (megatransfers/second or million transfers/second as Blameless stated). Next you'll be complaining about Windows using base 2 to calculate HDD size instead of base 10.

And for being someone pedantic, you're very much wrong on one of your points. The JEDEC standard for RAM is from PC3-6400 (800MHz or MT/S if you want to be technical) up to PC3-17000 (2133MHz or 2133 MT/s to be technical). Higher quality chips may be clocked and sold as PC-17000 modules, but they are not by JEDEC standards an overclock. In fact, you can buy JEDEC standard 1.5v CL11 PC3-17000 memory like this Corsair vengeance kit. Higher speed RAM may require an overclock for certain CPUs though as the CPU's IMC may only natively support PC3-10600 (like Sandy Bridge) or PC3-14900 (like Bulldozer), but you're overclocking the IMC to support the RAM's rated speed, not overclocking the RAM.
