What's the difference between 1333MHz and 1600Mhz ?

post #1 of 11
Thread Starter 
Hey guys, i've been looking to buy 4 GB of RAM for my new PC.
And i've found cheap 4 GB 1333 MHz one and a little expensive 2x2 GB 1600 MHz one.
So i've been wondering is it worth it to add an extra money for 1600 MHz or should i buy 1333 MHz cheap one ?
Also i won't be overclocking, and if i do what's the difference between it ?
Thanks

There is really no real world difference between the two.

I would go with the cheaper option, especially if the price difference is more than like 5 dollars

The difference between 1333 and 1600 is ability to overclock (1333 [CL9?] RAM is usually not binned to OC, and depending on platform can hold back entire system overclocks; it also results in lower performance - on some platforms such as AMD socket FM1 this could be drastically lower, causing 50% performance loss over higher bandwidth options). DDR3-1600 is commonly found at the same price or lower than 1333 during sales.

By all means you should buy 2x2GB for dual channel performance as well, it usually costs the same price as a 4GB DIMM, at equivalent speeds/timings. This will make more of a difference.

You can get it for almost zero difference in price nowadays. Like 3 or 4 bucks.

There are 4 GB kits of CAS7 1600mhz Mushkin with tight timings for like $40 right now

http://www.newegg.com/Product/Product.aspx?Item=N82E16820226103

CAS7 Gskill for $45

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231303

1.5v CAS7 Mushkin for $50 with even tighter timings as the 1.65v above. Bump voltage on that and I bet you get sick timings

There isn't a tangible difference when it comes to performance.

See my sig. biggrin.gif

@OP, it largely depends on what cpu you have. For sandy bridge, the difference can only really be seen in benchmarks. There is very little real world difference. But it's also largely dependent on the application. Even on the bit-tech review, there are some instances where 1333 outperforms 1600.

Edit: I just noticed this was AMD forum...

If this information will help, i will have Asus M5A97 Motherboard and a AMD Phenom II X4 955 Black Edition CPU.
So should i got with 2x2GB 1600 MHZ or 4GB 1333 MHz ?
Thanks

2x2GB > 4GB as stated above.

I recommend you to get 1600 MHz memory.
