I'm upping some memory on a few older machines that my wife and kids can use.
One of them has Corsair Twin Pair CM2X1024-6400 (XMS6405v5.1/XMS2-6400/5-5-5-12) memory. I wanted to get the same type and double the memory then noticed my local microcenter had one left in their store. Before I bought I researched it and noticed the latency on the store version is 4-4-4-12 while the memory in the PC displays on the stick 5-5-5-12. What will happen if I use the stick that displays 4-4-4-12 with the sticks that say 5-5-5-12? Not fully understanding the latency aspect and what might happen if I mismatch something. I saw they also had a matching set to another machine I have that has 1 GB of memory, and I could pick up Crucial Memory Crucial 2GB DDR-400 (PC-3200) DIMM Memory Kit (Two 1GB Memory Modules) which is exactly whats in the machine now other than the 2 sticks in there now are 512mb. BUT... it seems the older ram is more expensive? Is it just a supply and demand this? The above corsair memory is is $20 cheaper than that older Corsair memory... Just an observation.
