Questions - re Acer Extensa 2350 memory

I have a 2350 with only 256 mb memory. The chip is DDR 333 CL2.5 PC2700.
Q1. Would upgrade to 512 make a big difference to its speed? My thinking is that it is now quite an old machine and is only used for running MYOB, so overspending on memory that won't be fully utilised will be wasteful, so I'm looking at the smaller upgrade before I consider a 1GB upgrade, which I'm sure will do the trick.

Q2. Am I able to use any of these memory chips in this machine?
______________DDR2 667
______________DDR2 667/533
______________DDR 400/333
______________2100 266

Thanks in advance for sharing your knowledge

 

Q1. It wont be a major boost in speed but it will make a slight difference. The thing is, as you stated you want to ensure that your not throwing money at nothing... well if you go for the 512mb route you could grab something like this

Used for 15$, shop around you may get cheaper

Q2. It has to be CL2.5 PC2700 DDR memory.

 

Best shot is to stay with the same PC2700. Next is to go down with the PC2100. The PC3200 (400/333) might be hit and miss.

Windows always loves to have more ram.

 

Thank you both for your input. You have confirmed what I thought, but not being so familar with computers, I needed that.
Thank you

 

Definitely only put in DDR ram. DDR2 and DDR3 won't work.

 

Glad to help when possible.
