I Eat Pieces of RAM Like You For Breakfast.

I've heard from Stephen and George that I should be a discerning buyer when it comes to RAM and my new system. Good advice...I guess....am I looking for a good brand? Sturdy track record? Delicious fruit filling?

After speaking to my friend Eusuf,( who, after our conversation, I assume reads RAM trade magazines) he introduced me to the RAM feature: CAS LATENCY (CL).

In sum, for those who don't know, and I've only recently found out given a crap, RAM is set up in a grid. Cas Latency is a unit used to measure the time it takes to jump between columns on the memory chip. Feel free to clarify in the comments if you'd like, cause the details are quite in-con-se-quen-tial.

Anywho, RAM producers tout that their RAM is better then the competitor due to their better CL rating. 3, 2.5, 3, 2-2-2-5-1 etc. I've read a little about it, and it looks like the jury is still out how much of a performance boost you get from the lower numbers.

I called up Apple to ask them what the CL rating is for the chips they plan on installing in my new hotness. They passed me to tech support. They in turn emailed me a totally unrelated document about L2/L3 Cache.

It just seems to me that with the expense inherent in buying Apple, one might expect that they would maintain the hotness inside and out.

That being said, I'm going to wait until the computer comes to check out the CL rating of the RAM by cracking the case and reading the label. But even then, I'm not sure if I would spend the extra $20-$50 per chip for better rated CL RAM if I never would have known about it in the first place.

I guess I have Eusuf to thank to make my already neurotic purchasing process that much more crazy. [Thanks Eusuf]

Apple is most likely just buying ram from kingston or crucial, i would order the computer with as little ram as possible and then buy on the aftermarket from newegg.com or somthing like that. While a lower cl can help, you can only relly take advantage of these features if you can adjust the memory timings in the bios (not on a mac) so i would just look in case and find the product id on the ram and buy the most cost effective matching piece on line. the extra money is not worth the extra 2-3$ speed boost.

there also some argument that ram composition might be more important.
