1333MHz PC3-1066 DDR3 DIMM Desktop Memory KVR1333D3N9K2/4G (Electronics) I scuuessfclly paired these sticks with Kingston KVR1333D3K2/4GR from another retailer in a dual-channel RAM configuration. So that makes a total of 4 sticks, 8 GB. In order to take advantage of this much memory, I’m running a 64-bit operating system (as opposed to a 32-bit one). These are DDR3 memory sticks, so be sure you have an AM3 motherboard if you like AMD processors, or whatever on the Intel side handles DDR3 if you go for Intel processors.

Thanks for the tip! Knew this would be out there somewhere for a Linux machine since it can pretty much tell you every thing you want to know about your equipment. Glad there are people to pass on help.

Hi
@munzli
Thanks for your reply
According to wikipedia http://en.wikipedia.org/wiki/Ddr3 :
DDR3 modules can transfer data at a rate of 800–2133 MT/s using both rising and falling edges of a 400–1066 MHz I/O clock. Sometimes, a vendor may misleadingly advertise the I/O clock rate by labeling the MT/s as MHz.
1333 is data rate not clock rate :P
I addition wikipedia web page, there is one good table for comparing.

Thanks again.

@nima
DDR = Double Data Rate
so if a clock speed of 667Mhz is displayed the data rate speed is: 1334Mhz

Hi
Thanks for your good article
Unfortunately dmidecode can not give correct information about my memory!!
I have 4Gig DDR3 but dmideocde can not determine type my ram,and shoe “type= other” and “speed: 667Mhz”.
But speed of my ram is 1333 MHz.

Thanks for nay help or guidance

I get the following:
$ sudo dmidecode –type 17 | more

Is this a white box?? That is what I can make out. Just try the following command to see the server model:

dmidecode –type system
or
dmidecode –type 1

Gagan Brahmi,
Thanks, works well. :P

sajmon,

You can try using the following command combination and see if that works:

dmidecode |grep -A20 ^Memory

By: Gagan Brahmi

Gagan Brahmi — Wed, 27 Aug 2008 02:15:04 +0000

dmidecode –type memory

This should work as well :)
