Is an odd number of RAM sticks okay?

I have two sticks of 512MB of RAM in my computer. I recently put in another
stick of 512 for a total of three 512 sticks. Will this negatively affect the
performance of my computer? I ask this because I read that not putting RAM
stick in pairs will cause them to run in single channel instead of dual
channel and I'm not really sure what that means. Does this apply to just the
one stick or to all of them? I haven't really noticed an increase in
performance since installing the third stick.

Take one out and stick it up your arse.
 
You won't see any performance increase when configured for dual channel if the motherboard and / or the memory supports only single channel. You won't see any performance increase after adding the third DIMM if you don't run anything that uses more than 1 GB.
Make sure that the BIOS and OS recognizes all three of the DIMMs. You can run a performance test to check the speed with various configurations. Adding more memory, assuming that you did not have enough to begin with, will increase performance much more than increasing memory speed.

Thanks. My computer recognizes the third DIMM. My motherboard and original
memory support dual channel. If I have an odd number of DIMMs will all three
DIMMs revert to single channel or will only the third DIMM be single channel?

Finally you have gone completely over the top. It took a while but
everyone knew it was inevitable.

Now please crawl back in your hole and leave us alone. We do not need
your trolling here.

Normally I'd find that excessively cruel way to treat a
memory module, but considering the ridiculous cross-posting
level some kind of sacrifice must be made.

That wasn't the real Rod Speed.

There is no such thing as Single Channel ram.
 
All three will revert to single channel.

No, Dual channel is twice as fast


If a single channel of DDR266 memory supplies 2.13GB/sec of bandwidth, then
naturally a dual-channel memory controller (using two modules or sticks of
DDR266) can enjoy 4.3GB/sec of bandwidth.
 
That depends. You didn't bother to mention WHICH brand and model of
motherboard you have, so we can't even know if your motherboard supports
dual-channel memory.

Not quite, there is a slightl overhead but most important,
you'd have to be using the system for a purpose where the
memory was the bottleneck to get any benefit, THEN contrast
that with applications where one had needed more than 1GB of
memory... which brings up the central issue, that IF one
doesn't actually need more than 1GB, then why would they be
putting more than that in a system in the first place?

You could have fooled me. Both are obnoxious as all Hell.

But thanks for the heads up. Must give credit where credit is due.

RAM is macho.
