Just about to buy a new memory stick online. Can somebody tell me if the following is all I need to know for compatibility. My guess in that the "PC2700" is the physical and logical format of the memory.

Current Memory (spec as written on sticker):
"PC2700U - 25331 - A1"
"256MB, DDR, 333, CL2.5"

New Memory:
512Mb 184pin DIMM
PC2700 Standard
DDR Ram

Should be fine, PC2700 is the chipset that the memory uses, like your motherboard can probably support a few different types, but that's usually just for using older memory sticks like PC133, the performance jump isn't that severe, I think the revised socket design knocked the chip numbering system out of it's sensible little rut.

Go on www.crucial.com and follow their wizard thing to tell you what memory you need for your motherboard. You may find that they offer the best prices also.

Cheers. I think I have the right one. DDR only seems to be available in 184 pin DIMMs or 200 pin SODIMMs. I definitely don't want SODIMMs, the piccy's I have seen of 184's look right.

512MB, £34. Not a bad deal, methinks.

I'm old enough to remember when 4MB was £160, and doubled the amount you had installed

O_o 60usd is outragous for ddr, especially pc2700!

You should be able to get a 512mb stick for under 40usd..

http://www.newegg.com

Also, depending on the type of processor you have, you may find that your computer would run quite a bit faster with pc3200, if your processor supports it, and if you can clock it to 800mhz fsb.. If it's an 800mhz fsb chip and running pc2700 you're only running at 533mhz fsb (if it's stock)..

If you own a dell or compaq, or otherwise didn't build it yourself or have someone build it custom for you, then you're probably locked at pc2100 (533mhz fsb).. it'd be strange if you're running at 664mhz fsb, as intel doesnt make chips that run stock at those rates.. perhaps amd does though.. I dunno much about amd processors..

I guess I'd need more info to help you

Jerico...BIG difference in computer prices across the pond. It's pretty much Dollar for Pound, so what you have quoted is about right.

I'm sticking this in a laptop. It's an insurance replacement, I was given a Packard Bell, nice enough but extremely "Packard Bellized". 256 MB, as supplied isn't nearly enough to run it. Just M$ Word alone flags up a Low Memory warning.

Bit of a weird machine. Much larger than a laptop normally would be, with a hydro-cooled standard Intel processor and standard memory. The gfx card is a mobile one, though.

Woah.. was about to say that laptops don't use standard parts

Ahh sucks you have to pay so much more for parts :/

If you want to keep your existing memory, just buy your 2700.. if you want to replace it altogether, find out the speed of your processor (or the max speed your bios will let you set (fsb wise) and buy ram accordingly... (fsb / 4 = ramspeed)

pc2100 = 133mhz (533fsb) standard intel proc speed (for the celeron d or lower spec p4)
pc2700 = 166mhz (664fsb)
pc3000 = 188mhz (752fsb)
pc3200 = 200mhz (800fsb) standard intel proc speed (for a normal p4)

I got a magazine laying around somewhere that has 512kb upgrade boards for $300! Long live Amiga!
