After using 2gb of DDR3 ram over 2 ram slots over a available choice of 4, I decided to increase it to 6gb. I am not one of the most demanding PC gamers, or users, so budget DDR3 rams were what I sought. I found the Mushkin's at just over 25 pounds. The price seemed reasonable and the design was pretty nice and seemed solid, so I took the plunge and I am glad I did. These are by far better than my old pair of corsair 2gb XMS3 rams in look and seems durable enough. The heatsink's are stylish and add more to the cosmetic appearance of the ram than anything else. Using them for the last 2 months, I have had a pleasant experience and will consider the company in any future purchases related to memory. All in all, these very easily deserve the 4 stars I award them. 4 Stars, as I found out that these are not readily available on ebay and also the fact that the rams are 1333mhz as compared to 1600mhz available online at around the same price.
