Sorry if this is in the wrong forum.

I recently purchased 1gb of RAM from crucial. I have 2 slots in my computer and 1 of them already had a 1gb module installed.

I followed all the instructions for installation and I have done it before a few times on other computers with no problems.

If i go into my system properties under the general tab it still says 960mb.

Anyone got any ideas?

Help is much appreciated!

Thanks for the reply!

Should I not have around 2GB of physical memory now that there are 2 1 GB modules installed?

It says I have 2GB of total virtual memory, is this the total ram or is it the physical memory?

:thumbsup:

It is possible that the memory is not being recognized because of BIOS issues.

Do you know what BIOS version you have?

Sorry, I was really off-track in thinking there...it happens :thumbsup:.

The msinfo32 suggestion...did you follow that?

What is reflected?

Louis

First...you are assuming that you have a memory module which is correct for your system.

You haven't proven that yet.

System manufacturer and model?

What module did you purchase from Crucial? Read the invoice description/post same.

FWIW: All memory modules are not created equal.

Thanks for your assistance so far!

I have attached an image of my system info, I hope you can see it.

The module I purchased was "1GB 240-PIN DIMM 128Mx64 DDR2 PC2-5300 UNBUFF"

:thumbsup:

The module purchased should work, by itself.

Have you tried running it by itself?

I don't see that Crucial even has a listing for your system...but that mdoule should work by itself.

Memory modules purchases at differing times from differing vendors...should not necessarily be expected to function together correctly. Lots of variables, such as chipset, the modules themselves...it's not a given that they will work together.

Pull your old memory module and post whatever is visible for typed detail.

Thanks :thumbsup:.

I followed your instructions (tried the new module on its own) and my computer seems to be working at the same speed. I got the same data in the system info. I just tested an online game and it was the usual sort of frame rate.

What now? Have I wasted my money on this module?

Thanks for the help :thumbsup:

I have contacted Crucial and they told me I probably need to update my BIOS. When I look in the system information it says I have an American Megatrends BIOS.
I went to their website and used their scanner to determine if I had a genuine AMI BIOS. The scanner said I have an NEC motherboard. I have looked inside the computer and I dont know how to tell what type of motherboard I have.

I am utterly confused as to the next step. I am determined to not have wasted money on this RAM.

I have tried reading te help pages about BIOS and dont understand how to change it.

Please help!

Many thanks!

Specs at http://support.packardbell.com/uk/item/ind...2906&t=1409

No BIOS update since Apr 06, you probably already have it installed.

IMO...some persons with good intentions suggest BIOS updates...as a way of saying "I have no clue." My advice is to forget about changing your BIOS...if it's working now, it's OK until proven otherwise.

If you use the RAM configurator at any site...you do not go by the motherboard. You go by your system. PB iStart 2023. There is no compatible RAM listed for your system, using the Crucial configuratior.

Which I would consider a bad sign. I'd call Crucial back if they recommended that RAM and it doesn't seem to work. OTOH, if you selected the RAM on your own, you and Crucial have to work it out.

Your system can be considered old by computer standards and many RAM vendors will not carry RAM as dated as yours.

I don't know about the scanner at Crucial...I've never used it. But your system specs say it's a Gigabyte motherboard, assuming it's the orginal.

I got the computer under 3 yrs ago. Crucial did recommend the ram, I have recorded all e-mails... so hopefully they will refund it. Your right, the scanner could not recognise my system. I contacted crucial via email and they gave me recommendations.


Also the link you gave for my system is quite different than the system I have. ie the internal componets are different and i have windows xp media center edition sp3.


Thanks for your reply Louis! Can you think of anything else?

If anyone else can contribute I would be very grateful!

Check another site for memory information, e.g. :

Kingston

http://www.kingston.com/

Have regard to Louis' comments on Ram configurator sites.

Well...what differences exist?

Did you buy your system new?

The O/S being different is small potatoes, but any differences in components need to be noted.

OK, maybe I am a total idiot.

The system info says I have an istart 2023. However on the back of my computer it says I have a istart 2369.. see the link

http://support.packardbell.com/uk/item/ind...3801&g=1400

How am I supposed to know which one is correct?

Many thanks!!!

Me...I would simply open the case and take a look at the components.

If the motherboard installed (motherboard model usually are imprinted on the board and visible to anyone with the case opened...matches the basic specs for either iStart system...we're good.

But...changing a motherboard is pretty routine for many users...and if you did not buy the system new...any knowledgeable person could have changed the motherboard.

So, you need to take a look and match or attempt to match the specs listed for those two iStart models.

Louis
