Hey, everyone,

I want to upgrade the RAM from current 6 GB to 12 GB, but am confused by the RAM specification and model number.

The RAM I am currently using is Corsair DDR3 CM3X2G1600C9D6 XMS-1600 9-9-9-24.
However, I couldn't find the same RAM on Corsair's website. After some googling, this model seems to show up in sites with Japanese or Korean characters. So, I tried to look for alternative solution.

First one:
CORSAIR XMS3 DDR3 1600 (PC3 12800) 9-9-9-24 Model TR3X6G1600C9 $159.99 Newegg.com (Link (http://www.newegg.com/Product/Product.aspx?Item=N82E16820145222&nm_mc=OTC-pricegrabbermerch&cm_mmc=OTC-pricegrabbermerch-_-Memory+%28Desktop+Memory%29-_-Corsair+%28XMS+Series%29-_-20145222) )

Second one:
CORSAIR XMS3 DDR3 1600 (PC3 12800) 9-9-9-24 Model CMX6GX3M3A1600C9 $139.99 Newegg.com (Link (http://www.newegg.com/Product/Product.aspx?Item=N82E16820145258&cm_re=cosair_xms3-_-20-145-258-_-Product) )

I can't really tell the difference between this two models? Also, what is this Latency 9-9-9-24 for? Can I have 2 sets of RAM (9-9-9-24 and 8-8-8-24) mixed on my motherboard?

Thanks,
Jason

It just default to the timings of the slower set, but worry not, ram timings aren't tremendously meaningful unless you're overclocking. At stock the differences in real world performance between budget ram and expensive ram is entirely negligible. You will note significant differences between timings in reviews only, which are using non-real world benchmarks like SiS Sandra.

Thank you all,

I guess the difference between these two models is the second is the newer model. (found this when locating the first model on Amazon Link (http://www.amazon.com/Corsair-TR3X6G1600C9-PC3-12800-1600MHz-Tri-Channel/dp/B001K56XW8) ) Not sure if there is any improvement on the new model. It is cheaper though. Is this normal where the newer model is cheaper listed with the older, more expensive model on the market the same time?

Much like with any other type of product, as production improvements are made, yields increase, speed increases, quality increases (hopefully), etc. This leads to you being able to buy a newer revision of the same product with improvements. Yes, older product does sit around here and there based on what type of return for credit policies the retailer has with the vendor.
