PC100 SDRAM Modules?? Help

[smulverwell]

Hi, I have a Fujitsu Siemens LIfebook E6560 laptop...

.... With a little help from this board I have recently installed a copy of XP Pro, which runs (reasonably) well on my laptop... Unfortunately there are times when I require to open a larger amount of applications than I would normally, and this is when my laptop begins to struggle a little.

The laptop isnt of much worth, it's just something I use in college (I have a desktop at home), which is why I was a little shocked when I saw the prices for new RAM modules to fit my laptop! They appear to be the most expensive!!

I ran a stats program on the laptop to identify the type of RAM required and I think I know what I need now, but would be grateful if someone could confirm. I believe I need a PC100 144 Pin SDRam Module.

(The stats were this: Type = SDRAM, Frequency = 100mhz, FSB:RAM = 1:1, CAS# Latency = 2.0, Chipset = Intel 440ZX, Motherboard = Fujitsu Biscaynese)

I know that I currently have two 128mb modules installed, and due to the high prices (im a student lol) I can only just stretch to a 256 module. I would prefer to just remove both 128's and install a 512 module if it weren't for price! (512 is the max supported, btw)

Firstly, can I mix a 128 and a 256? Also, have I identified the correct memory type? Why is this memory so expensive? And also, does anyone have the required 256 or 512 module lying around that would willing to sell for a reasonable price? I am in the UK, but would happily pay to have it shipped.... A 256 module over here costs the equivalent of $75+ (US) and a 512 is about $110+ (US), and thats second hand on Ebay - the retail prices for new modules are double that! Since I'm unemployed at the moment these are a lot of money!!!

If anyone can help me to answer any of the above questions then I would be very grateful, and even moreso if someone has a module theyre willing to sell!!!

Thanks in advance guys,

Matt

smulverwell,

Have a look here.

You can mix a 128 and a 256, this will give you a total of 384.

Do a google search for more suppliers, there are plenty and you may find they are not as expensive as you think.

Hey,

Oldtimer - I wish I could afford a new laptop, but at the moment money is literally non existent!

Highett - thanks for the link thats a little expensive, but I followed your advice and even though I've googled it before, I got some much better results - $33!!!!!

However, now I'm a little bit confused as to whether I need an 8 chip or a 16 chip, since this site says something about this module only being used if your laptop supports 512 per slot, or has intel 815E Chipset. Mine supports 512 total, but I'm not sure about 512 per slot, and I have an intel 440 ZX.

Here are some of the others that cropped up:

Any advice would be appreciated, sorry if what I'm asking is a little obvious!
