This is preorder but it seems cheap compared to standard memory kits and if you order at this price you should get it.
The reason these are a great buy is because they are cheaper than the standard XMS3 memory and they run at the new 1.5volts and the best bit is they are 4gb sticks so this means those that have only 2 dimm slots can get 8gb of very fast memory in there board instead of the regular 4gb or if your like me and have 4dimm slots you could have 16gb of memory although i cant really see why you would need that as 8gb is more than enough for any task.
These kits come in other timmings and speeds but i thought id post the 1600mhz kit as these are the sweet spot with memory and after reading the link below it seems that this memory is monstrous when overclocked with it reaching 1800mhz just buy upping the speed and for those who fancy putting the standard 1.65volts in 2000mhz is easy doable.
