Memory Sticks for a PC running XP

  wee eddie 12:46 15 Oct 2008

Which would be better?

2GB of the Fastest that the MOBO can support or 3GB running at the speed of the Old Sticks, which is probably the slowest that the MOBO will support.

In other words: Do I chuck out the 2 old, 512MB, Sticks or not?

In the latter configuration, the old sticks would be installed in the Secondary Slots.

I would first let the crucial scanner look at your system. Then if there is nothing wrong with the existing leave it in and fit the max you can. Be aware that 32 bit xp cannot handle above 3GB without problems.

Depends what you use the PC for and what the difference between slowest and fastest is.

For many uses, 2GB would be more than enough. In fact 768MB would be enough for general browsing / office application use. Larger amounts are often needed for games, photo / video editing etc.

If you really need more than 2GB, I would guess that 3GB of the slower memory might be better as it would minimise use of the page file on disk.

BTW, "memory sticks" will make many think of pen drives.

I've already visited Crucial. My MOBO requires that the RAM to be installed in Pairs.

I currently have 2 x 512MD of RAM, Crucial are offering 2 x 1GB Sticks, of suitable RAM, at a good price.

The reason for the visit to Crucial was that I appear to be using Virtual Memory, more and more often.

do RAM sims still 'need' putting in in pairs ?

I'm no expert Eddie, & of course know nothing about your system or needs,,,, but if Crucial recommend 2Gb for your set up, & you can afford the 2 sim's - i'd go for that. You are keeping the integrity of the machine in tact.

I have an ACER T120 & like you I had 2 x 512's. I couldn't afford two 1gb's in one go, so got one at a time so had 1 x 1gb & 1 x 512mb - no probs at all.
I added the other 1gb later.

good luck

However I am still none the wiser.

Put in other words.

I still do not know which will process "more" information. 2GB of the fastest RAM usable or 3GB of RAM working at a considerably lower speed.

I shall just have to "Suck it and see".

If it's any use. I benchmarked the same RAM running at 800MHz and again at 1066MHz on the same system. Difference in performance was between 3-6% i.e. undetectable in normal use.

I go with what DieSse suggests. Don't mix different RAm unless you have a really low spec system that isn't stretched.

I've only noticed a few % improvement in switching from 2GB RAM to 4GB (3.2GB available) in the same system and then it's only in video editing, about 20-30 seconds quicker on a 7GB render.

I, of course, used the word "Process" in the context of "In & Out" and the speed & volums at which the information passes through.

Unfortunately I don't have the speed of my old RAM, but I know that I purchased it over 4 years ago to upgrade my previous PC, and it wasn't the fastest available then.

As both Crucial's 2GB packages are the same price, I shall go for the faster, and shall then start with just the 2GB installed. Later I shall add back the 2 x 512MB sticks and see if I notice any difference.
