Default 9-9-9-24 versus 9-9-9-24-2N. Whats the difference?

Can someone explain to me the theoretical and practical differences between purchasing a set of memory rated with a timing of: 9-9-9-24 versus one rated with a timing of 9-9-9-24-2N? Is it okay to purchase 2N memory or is it junk memory? Thanks for all comments.

The 1st is rated SLIGHTLY faster when you set the timings. Are you building a gaming rig? If so, then well yeah the 9-9-9-24 is faster, you MIGHT see higher FPS, but it will be minimal, but you also may not. I would buy the cheapest.

Actually, it's likely that the 9-9-9-24 defaults to 2N as well. Most memory in fact is rated at 2N, even good memory.

That being said, running at 1N is faster, and it might be possible to manually configure 1N with either set of memory - you really need to provide specifics on the memory kits you are referring to.

Default The memory sets I am comparing are these...

Both sets are G.Skill Ripjaws series 8GB kits

And yes, $45 for 8GB of DDR3-1600 is an absolute steal!

All "2T" DDR3 that I've used runs 1T just fine on my Phenom II platform.

For gaming - buy the cheapest, it will be -perfectly- enough for any games.
For any serious video rendering and all those kind of CPU demanding fancy programs - definitely the faster one.

No reason to spend the extra cash on the so called faster ram, just use the 2N and run it at 1N.

No it's not faster. Actually, if you bothered to follow the links and then go to G. Skill's webpage for both sets of RAM, both are rated 9-9-9-24-2N.

Both are identical, just the heatspreaders are different, one Ripjaws and one RipjawsX. So, just the marketing is different.

OCZ's been doing this for years.....using the same DIMM with different heatspreaders and marketing the sets towards different niches.

both of the timing are only part of the timing settings used to operate the RAM. In this particular case, both set use 9-9-9-24, so i'm not going to explain that. The key is, why the first one doesn't have 2N? Well, because 2N is so common that usually people don't put it in. Having it doesn't mean the RAM runs faster.

2N or 2T refers to the command rate (CR). The lower, the better.

My 1st response was not based on the links. He asked what the difference is between a ram using 1N and 2N. The 1N is a faster command rate ram. The post came off as a question about any ram, since there was no specific link when it was asked the 1st time.
