DDR3 - why are there pc3-10600, pc3-10660 and pc3-10666?

DDR3 1333 - why are there pc3-10600, 10660 and pc3-10666?

the local store in our area only sells PC3-10600.

After researching around, i found that there are pc3-10600, pc3-10660 and some pc3-10666.

At newegg.com, there's only 1 pc3-10600 (trancend tripple channel), there's also only 1 pc3-10660 (geil dual channel), which raised some red flag.

so i was wondering, are these all the same?
will there be some compatibility issues?
should i stay away from these ddr3?

or is it just naming?

thanks

If i'm understanding your question correctly. Yes they are all the same.

Yes you should stay away from ddr3 unless your using a cpu that is an i7.

If your looking to do an upgrade then make sure you match up your ram with your motherboard. your motherboard should support ddr2 or ddr3 [ddr(1) for a legacy computer]. These need to match up.

yea. im looking for ddr3 rams for my corei7.

im currently making some listing of things to buy.

it just bothers me that there are different numbers - 10600/10660/10666

Like Jack Burton says "When in doubt, pick the highest number"

Hi,

I have 4 memory modules, 2x1GB Centon PC3-10600 and 2x1GB PC3-10666, they are not compatible, why? Simple, some latencys that the memory have on internal chips.

If you want quality memories, PC3-10666 are the right way (667 MHz).

If you want value memories, PC3-10600.

I hope that this help.

Regards!!

PC3-10666 isn't 667Mhz unless i got it confused. I just ordered 10666Mhz ram and their 1333MHz says where i ordered them from. As for what one to go with the 10666mhz one would be a lot better.

Just make sure your motherboard supports the DDR3 versions before u buy em If they do than grab a pair or two of 10666.

DDR = double data-rate RAM.

1333 / 2 = 667

Or more accurately 667 * 2 = 1333

Why, I am working on putting together a computer for my first build. So far I have Cooler Master GX Series RS650, And an AZZA Solano 1000R, And an Intel E8500 Core 2 Duo,.....And I just ordered and got the motherboard, I got a Gigabyte GA-EP45T-USB3P.

It says The Motherboard supports the Intel Core 2 cpu's and onlr supports ddr3 memory. So am in in trouble with the parts that I ordered?
Like I said this is my first time attempting to build a computer.?

you don't have to have an i7 to run DDR3 or even 1333 at that. That is a misconception.
i'm building an intel atom based system right now with DDR3 PC3-10600 clocked down automatically to meet the board specs.

No you should be ok. i would go for the PC3-10600 DDR3-1333. Because its the highest compatible with your board and not so expensive either.

your board
is as follows for ram specs:
DDR3 2200 (OC)/1333/1066/800
ddr3 2200 on that board only with (OC) overclocked memory. Which if you reference intel on this, it would probably be 1.9v-2.1v
which is pretty high compared to standard memory voltage 1.5v. And that can usually be accomplished through the Bios. but it has to be the right ram.
Otherwise sitck with 1333/1066/800

see the table below taken from wikipedia o debunk some of the misunderstandings about DDR3 ram speeds
http://en.wikipedia.org/wiki/DDR3_SDRAM


so, sometimes ram can be backwards compatible.

This was the case with DDR2 and DDR being able to clock down in most systems. Only when specified by the manufacturer i've seen it where ram of higher speed would give you the beeping alarm to let you know you were using incompatible ram.

Thanks, for the info, I posted the question about 6 months ago since then I used PC3-10600 DDR3-1333 menory and it turned out awesome. Great gamming computer!
