gunners009, let me clear the doubts regarding Ram.
The performance of ram depends upon two factors:
1. Speed: It determines the data transfer rate of a Ram, i.e. how much data can be transfered in unit time. So more the speed, more the data Transfer rate. In your case you can't go beyond 1333 MHz speed due to the H67 chipset restriction.
Cache Latency: It determines the response time, i.e. the time required between a request of a particular data has been made by CPU and that specific data is available to CPU. Normally Ram modules are devided into multiple rows with each row devided into severral columns. This columns are called memory block and the smallest unit of a memory. When a data is placed into Ram, it is devided into several small blocks. For example if the block size is 512 Bytes and the data size is 2KB then (2KB/512Bytes) = 4 memory blocks are required to hold the data. So when a request is made by CPU, Ram needs to some time to find out at which memory locations the data is distributed. So less the latency, faster the access of data.
In your case, both the Corsair Value Ram 1333 MHz and XMS3 have CL9 cache latency. So in default setting there will not be any performance improvement with XMS3.
Now I think you get the idea: With your H67 chipset, both the Corsair 1333 MHz CL9 value Ram and 1600 MHz CL9 XMS3 will perform almost same unless you reduce the cache latency of any of them by changing the BIOS setting. AFAIK, XMS3 can run @ CL9 in 1333 MHz speed, Our forum member Sukesh has done it. So if you are okay to play with the Ram timing setting, go with XMS3. Else get the Value Ram.
