Hi,

Just wondering in general if there would be a noticeable performance hit going from x2 1gb in dual channel to x3 1gb?

As I'm thinking of adding some additional memory to tide me over for a year or so before i do my next major upgrade, or would i just be better off going for a x2 2gb kit?
 
adding 2 * 2gb will give u dual channel mode, otherwise the slower 3 * 1gb will run in single channel mode.. If however your using 32 bit operating system then u wont really see much off above 3.2gb off memory getting used........ thats the 32 bit operating system, 64 bit operating system u will depending on the memory demanded by the Program used etc..

btw cant you add 2*1gb sticks to your 2*1gb sticks giving yuo 4 gb memory and 2 dual channel mode.
 
Hi,

Thanks for the reply, I fully understand the 32bit limitation of only addressing 4gb of memory in total, which is why I figured that if the performance hit of dual channel to single channel isn't great I could just stick in another 1gb stick. The reason being in fact that I do have x2 2gb kits, however I've had to use of the sticks in another workstation.

So would you think I'd notice the performance difference (in real world usage) of single channel compared to dual channel?
 
tbh the only way to find this out is to run the pc with the 2 1gb sticks do some kind off memory test, then switch off then install the extra 1gb stick then do the same test to see if there is a noticeable difference.... personally I would always run my pc's in dual mode .... it's the fastest way to expoilt the speed of the memory chip.
