Mixing similar memory kits

post #1 of 7
Thread Starter 
I read this on corsair's FAQ section:
Quote:
Q. I have two Corsair Memory modules that work fine together but when I add two more modules of the matching part number, they won’t work.

Answer:

Each kit of Corsair Memory is tested to run at its advertised settings in the configuration in which they are sold. If you purchase a 4GB kit (2x2GB), then we can only guarantee its performance and compatibility when using it as a single kit. To ensure the best results with more than two memory modules installed in the same system, it is best to get a kit which has been tested to run in that configuration.
n.

So if I bought a low profile vengeance kit of 4GB (2 X 2GB) and wanted to install another kit of exactly the same type (same model number of the modules) to make a total of 8GB, would I have problems?

you should have no issues at all running two kits of the same modules.

The following conditions do not need to be met:

Same brand
Same timing specifications
Same speed (MHz)

Memory channel speed is decided by the slowest DIMM module populated in the system.

you would not provided they have the same speed and the CAS Latency (Not much sure about the latency part)

If the added memory is exactly the same model as the one you already have then there is very little reason why they shouldn't work together.

That is also what I thought but then there's this FAQ by corsair which totally condradicts it.

Sam OCX is correct.

The reason for that statement by Corsair is that they often change the ICs used in any particular product line. They differentiate this change in ICs by giving the product a new "version #". If you look at the label of a Corsair module, in addition to the Model number, timings and voltage, you will see something that looks like "v4.13", or "v5.11", etc. As long as you match your kit with an identical model and version number, then you have for all intents and purposes, bought a quad kit. If you don't match them you might encounter compatibility problems, but only likely if you try to overclock them any. At stock clocks they would probably work fine together.

How long ago was your current kit purchased?

Thanks for the replies everyone. I haven't purchased any kit yet, still waiting for Haswell.
