Question on memory chipsets
I work for an online computer sales store similar to newegg. I was recently writing an ad for some DDR2 memory and, while checking the supplier for specs, I noticed that they (our supplier) actually sold the same memory with four different chip makers: hynix, micron, samsung, and value.
My question is this: What is the importance of these different chip makers?
I assume it has to do with compatibility but, as i'm not an actual tech, I don't really understand memory compatibility as I should. If it is a compatibility issue, how does one determine which chip type they need to purchase?
Thanks for any and all responses!
