I am amazed to find this product work too good. I am now using a total of 12GB (8+4GB) RAM from the same company (G-skill). The transfer rate has risen from 6MB/s to about 27 MB/s. The system is now performing super fast than before and the RAM is supporting at its best for animation software and off course gaming too. I highly recommend this product for those who are looking to upgrade their PC with an economic and work effective product. One more thing is that the same product also comes with cooling cover. It is mandatory for the customer to look out for CPU size and RAM slot spacing when they opt for purchasing RIP JAW version because it is difficult to insert two RIP JAW model RAM on the same board. Above all this model is very good both in performance and durability. I also acknowledge Flipkart for making a good package (came in a cute little cardboard box) and very fast (delivered in one day) delivery even during festive seasons. Hope my review helps the customers.
