should over 512 be buffered?

i recently bought two corsair 512-2700c2's (seperately), and when i looked at my system summary in sandra, it told me these two things..


Tip T100 - Large memory systems (1GB or greater) should use Registered/Buffered memory, especially if more than 2 are installed on the same channel. This improves signal quality by reducing the load on the chipset channel. While these modules add an extra clock delay due to the on-board buffers (thus CL2 effectively becomes CL3), the stability will be worth it. Server chipsets with many memory slots generally require Registered memory.
Fix: If you plan on adding more memory, consider replacing the modules with Registered/Buffered modules. Do note that you cannot mix Unbuffered and Registered/Buffered modules on the same channel, but you may be able to if the chipset has multiple memory channels.


Tip T101 - Large memory systems (1GB or greater) should be ECC/Parity. Since the probability that a bit will be corrupt is the same or increases with module density, the bigger the module, the bigger the overall probability that you will get one or more corrupted bits. While these modules add an extra delay on partial writes (e.g. less than data width) as parity for the whole line must be re-calculated, the stability will be worth it.
Fix: If you plan on adding more memory, consider replacing the modules with ECC/Parity modules. Do note that running plain and ECC/Parity modules will turn off ECC/Parity for the whole memory array.



what should i do?

unless you're doing CAD or Photoshop or premiere or soemthing like that it is not worth is to use Registered/Buffered or ECC memory because of the slowdown and the extra cost
