Dual Channel DDR question

one of my 4 memory banks is bad.
If I take the bad one out and run it with 3 DIMMs will the other 2 continue to run in dual channel mode?

Re: Dual Channel DDR question

fairly certain the answer is yes
the 2 sets of banks are separate from each other

That wouldn't really help though, would it? Wouldn't the CPU accessing the bank with 2 modules have to wait for the one with 1 module?

I have 3GB in this computer, 2 in one bank, 1 in another. CPU-Z tells me I have 3GB, Channels # is Single.

Dual channel only gains you about 3% in speed anyway.

Re: Dual Channel DDR question

It will most likely slow down as all the traffic will move through the memory controller. It will depend on what you're doing, what the system needs for memory at the moment, etc.

If the task only used the working dual channel banks, it should work as advertised. But if the task requires more memory, it will have to wait for the other single bank to move the traffic to the memory controller. All in all, as X said, the performance gain/decrease probably won't be noticed, aside from the fact you're down one bank/stick.
