I have an old Dell Deminsion 8300 desktop. Its upgradable to 4gb DDR SDRAM 400 PC3200. Right now it has 2 256mb and 1 512mb chips installed. Im ordering 2 1gb chips now. Question is... I install the 2 1gb chips in the first 2 slots, what chips should i use in the other 2 slots, should i just put the 1 512 back in, or pair the 2 256's, or can i use the 1 512 and 1 256? i read somewhere for DDR2 ram that its best to have them paired with same chipset. not sure if DDR follows the same rule. would the paired 256's run better than the single 512. im sure the ones inside right now are all PC3200, as are the ones i just ordered.Sorry if his sounds confusing, and thanks for any answers.
I don't know that particular machine, but my instinct says to put the 2 256mb sticks in the second slot of each channel, so that they are balanced (each channel has a 1GB and a 256MB stick). The performance improvement of an additional 256MB (by using the 512MB in place of a 256MB stick) would be negligible at best, quite apart from running into the memory limitations of 32-bit Windows.
