Question about 3GB memory

post #1 of 10
Thread Starter 
Hey guys,

I've got a question. I've been looking for answers elsewhere on the internet but couldn't really find anything, just some statements with poor
back-up. I overheard the owner of the shop where I buy all my parts saying to a customer, that if you plan on upgrading your computer with more memory, you have to double what you have got now because otherwise windows will run unstable and you're performance will be much
worse then before. In this case somebody wanted to upgrade to 3GB from 2GB.

Is there any truth in this statement, or is it just a sale technique. I thought myself that I could make some sence, cause I always see the
warnings in mainboard manuals that to be able to run dualchannel, both channels need to the same amount. Perhaps I just answered
my own question, but some help would be apreciated.

My apologies if I'm asking something already perfectly explained elsewhere.

it is just a sales pitch windows or any other os or program will not run unstable just be cause of a odd ammount of ram but they will run slower due to being in single channel but this is only about 5-10% so you wouyldnt notice much

It probably wouldn't be "unstable"...it's just that in order to have dual channel enabled, you need two identical ram sticks and they don't make 1.5gb sticks (as far as I know) so the sales dude has a point. He shouldn't put a 1gb and a 2gb stick in order to achieve 3gb, if he doesn't want to sacrifice performance (who does?).

What's 5-105

I thought dual channel increased overall system performance by like 5%+ ??

Yeah he meant 5-10%.. check out the character above the 5 key

Yeah, it shouldn't have that much performance impact. The memory bus is hardly saturated as it is.

Come to think of it, nothing in a computer is really saturated, apart from the graphics card's memory bandwidth, which is used an awful lot.

Ok thank you guys. I'm not planning on upgrading myself, system running fine as it is. But this just kept haunting in my head, the performance
part about Dual Channel I figured out myself, but why windows (or any OS) would become unstable was beyond me. And isn't true

I can sleep again now

Ahhhhhhhhhhhhh....

You can run Dual Channel with 3GB easy: 2x1GB + 2x512MB.
Once again...

Whaaaa? You can't run dual channel in 4 slots......can you ? I thought the two blue slots (or whatever color) are the dual channel slots....stop messing with me !

I used to run 4x512 dual channel...

Now I run 2x1ghz and 2x512mhz and its perfectly fine and 3ghz dual channel...

As long as both sets of mem are dual ch. and put in the rights slots it's good to go...
