Specs: Windows XP, Pentium 4 HT 3.00 Ghz, 2

I have a computer I bought a couple of years ago.....

It's a Fujitsu Siemens computer and has 512 mb of RAM already in it.

As far as I can tell this is installed as 2 x 256 mb.


I would like to install 2 more sticks of 256 mb RAM to take the total up to 1 GB.


The problem is, I can't find out for the life of me, just what RAM my computer will accept...

heres some info I collected from a program (everest)

I don't know how to interpret this.. I reall simply need to find out what I need to buyy... what type of RAM, what speed or RAM, and then go out and get it...

I just want to upgrade to GB, PLEASE help me!


I tried that crucial RAM website, but it does not have my motherboard, model number etc on it's list.... my computer doesn't exist.


If you need more info just tell me how to get that info and I'll give it.. thanks for any help....

looks like ur motherbaord is supporting ddr ram ... the type of ram u need would depend on what the other type of ram are...if the 2 sticks are pc2700 get pc2700...if the two sticks are pc3200 get pc3200..it should say on the 2 sticks what speed they are..if u can opost them here

Its all good

Yes, I opened my computer just now and found stickers on the RAM sticks..


These read:

PC2700U-25331-Z

M368L3223ETN-CB3

256MB DDR PC2700 CL2.5


That's everything written on the RAM...


what exactly do I need to get/what speed?

Your board is made by Giga-Byte for Fujitsu Siemens.

"The problem is, I can't find out for the life of me, just what RAM my computer will accept..."

"Module Name Samsung

Module Type Unbuffered
Memory Type DDR SDRAM
Memory Speed PC2700 (166 MHz)"

You have two 256MB sticks of Samsung PC2700 DDR-SDRAM.

Your CPU is running at 200MHz (800FSB) so your PC2700 (166MHz) RAM is already bottlenecking the system. You should have PC3200 (200MHz) RAM, but if you pair it up with the PC2700 you already have, all four sticks will be forced to run at PC2700 speed.

In short, get rid of the 2 x 256MB PC2700 & replace them with 2 x 512MB PC3200.

Wait... I can't add 2 more the same as what I have now to make 1 GB?

I'm not made of money :(

I really need to know if I can just add 2 more PC2700 and get my extra RAM?

You certaimly can add 2 more 256MB sticks of PC2700 if you want to, but understand that you should be running PC3200.

Apparently you don't understand the relationship between the CPU & RAM speed. Your P4 CPU is running at 200MHz, but your PC2700 RAM is running at 166MHz. In other words, the RAM is holding your system back from peforming as good as it could.

Sell your 2 x 256MB PC2700...it's worth about $30-40. Then buy 2 x 512MB PC3200 CAS 2.5 RAM for about $70.

how about this?


Part Number: CT2KIT6464Z40B
Module Size: 1GB kit (512MBx2)
Package: 184-pin DIMM
Feature: DDR PC3200
Configuration: 64Meg x 64
DIMM Type: UNBUFFERED
Error Checking: NON-ECC
Speed: DDR400
Voltage: 2.6V
Memory Timings: CL=3
Specs: DDR PC3200 • CL=3 • UNBUFFERED • NON-ECC • DDR400 • 2.6V • 64Meg x 64

I I buy that would it work?


please remember I'm in the UK.. so I'm looking at uk sites.

Some say unbuffered, some don't.

Some say non ECC, some don't.


Would this be ok for my computer?

"Memory Timings: CL=3"

It should work but for better performance you'd be better off getting RAM that's CL 2.5

Don't get ECC RAM.

ok, I ordered the RAM from crucial and it arrived in less than 24 hours!

But, obviously, I douldn't use their tool and had to pick out the RAM myself.

I opened my computer, removed the old RAM, then tried to put the new RAM in....

My attempts failed, the DIMM slot was EXTREMELY tight fitting... brute strength wouldn't do the trick.

To make matters worse the slots are hidden between a massive pile of wires... which made things very awkward.

Well.. after 15 mins of that I decided not to break my new RAM any more than I already had, and went back to my oldRAM to practice.


I couldn't get the old RAM in either... and after 30 mins ofthat I finally... finally managed to work out a way of maneuvering the RAM into position with a combination of skill and pushing hard :P


So... I went back to the new RAM and eventually got both new sticks into their slots.


Then i set up my computer and got ready to find out I'd broken it, the RAM, or some other problem.


Computer booted up fine and system properties say 1 GB of RAM.


yay!


Veyr hapopy, thanks for the help, I'm done :)


Pulled a muscle in my hand though :P
