I'm reading a lot about the affect of proper memory configuration on the performance of FSX without understanding it. Based on the following CPU-Z reports, do I need a different configuration of memory modules? I have a matched 1GB pair plus another 1 GB matched pair in 4 slots.Slot 1-2: OCZPC2-6400 (400 MHz)CAS# Latency = 5.0RAS# to CAS# = 5RAS# Precharge = 5tRAS = 15tRC = 23Voltage = 1.8VSlot 3-4: CorsairPC2-6400 (400 MHz)JEDEC#2CAS# Latency = 5.0RAS# to CAS# = 5RAS# Precharge = 5tRAS = 18tRC = 22Voltage = 1.8VEPP#1CAS# Latency = 4.0RAS# to CAS# = 4RAS# Precharge = 4tRAS = 12tRC = 22Command Rate = 2TVoltage = 2.1V

Not sure what motherboard you have, but in my experience slots 1 and 3 are the first channel, and slots 2 and 4 are the second channel. They are usually coloured the same to denote which slots belong to which channel. If that is the case, then your current setup is incorrect and you need to put the OCZ memory in slots 1 and 3 and the Corsair in 2 and 4 which will give you correct Dual Channel operation with the matched pairs of sticks.As for the timing and stuff, I'll leave somone else with more experience than me to comment on that :(

Thanks Carl. The motherboard is noted with my signature below. I checked the manual, which ids the slots as A1, B1, A2, B2, and A1 + B1 as one pair and A2 + B2 as another pair for dual channel triggering. That is the way my matched pairs are installed.The listings in my first post are from the SPD tab of CPU-Z. The following is from the Memory tab:Channel # = DualFrequency - 376.8 MHzFSB DRAM = CPU/8tCL = 5.0 clockstRCD = 5 clockstRAS = 5 clockstRAS = 18 clockstRC = 23 clocksCR = 2T

Fair enough, thought it best to check though :((That'll teach me to read people's signatures too!)
