ashacat Posted September 19, 2007 Share Posted September 19, 2007 Hi guys, I have just transfered the RAM module from my new Acer laptop into my old Acer laptop. I did it myself (first time) and it all seemed to go OK (??) but when I turn it on and go into system properties it still shows the pre-upgraded level of RAM. Any ideas as to what has gone wrong?

whimsy Posted September 19, 2007 Share Posted September 19, 2007 Two possibilities spring to mind. 1. The RAM is not compatible. Check www.crucial.com for a good compatibility tool. 1. The RAM is not seated properly in the slot. Double check that it is pushed all the way in and the retaining clips click closed. Link to comment Share on other sites More sharing options...
ashacat Posted September 19, 2007 Author Share Posted September 19, 2007 Sorry. OK. New Laptop: Acer Travelmate 4720 Old Laptop: Acer Aspire 5500Z Old laptop has 2 ports, it previously had one 512 RAM installed New laptop has 2 ports, it previously had two 512 RAM's (I have taken one out to put in the old one) Link to comment Share on other sites More sharing options...
ashacat Posted September 19, 2007 Author Share Posted September 19, 2007 I assumed that if the RAM module was the right shape and fitted in the slot that it was compatable, is this incorrect? Link to comment Share on other sites More sharing options...

New Laptop: Acer Travelmate 4720 Old Laptop: Acer Aspire 5500Z Old laptop has 2 ports, it previously had one 512 RAM installed New laptop has 2 ports, it previously had two 512 RAM's (I have taken one out to put in the old one) Some Acer having compatibilty issues with Memory. Try to use both memory from the new Laptop in the old one because they worked in the new Laptop! I'll check the modell for Issues. Link to comment Share on other sites More sharing options...
sniffdog Posted September 19, 2007 Share Posted September 19, 2007 Yes, the RAM has to be of the same kind or problems may arise. Link to comment Share on other sites More sharing options...
ashacat Posted September 19, 2007 Author Share Posted September 19, 2007 Here's what both RAM's say on them... Original: 512MB 2R*16 PC2-4200S-444-12 Additional one: KN5120G019717D66472000 Link to comment Share on other sites More sharing options...

Anyway the 5500Z uses DDR 400 or 533 while the 4720 uses DDR2 667 Memory. Try to use the both new memory in the 5500Z, if they not works is an incompatibility with he new memory!

Try to use the both new memory in the 5500Z, if they not works is an incompatibility with he new memory! Oh right, so they use different types of RAM even tho the shape of the ciruit board is the same, how annoying! I can't take the other RAM out of the new computer because it is still under warrenty (I had it upgraded at the Acer shop and they let me keep the old RAM). So it doesn't look like it's gonna work Mai pen rai. Many thanks for all your kind help everyone, it would have taken me hours of internet trawling to discover this!!

Mrjlh Posted September 19, 2007 Share Posted September 19, 2007 (edited) Hi guys,I have just transfered the RAM module from my new Acer laptop into my old Acer laptop. I did it myself (first time) and it all seemed to go OK (??) but when I turn it on and go into system properties it still shows the pre-upgraded level of RAM. Any ideas as to what has gone wrong? In case you tried everything that was already suggested and it still didn't work I think here's your problem: Go to ....http://www.memoryx.net/...hopefully you'll figure this out like I did. What is you complete model number for the Travelmate 4720? You have three choices of memory. (notice bus speeds of only 533 and 667) Acer TravelMate 4720-6182 uses (DDR2-533MHz) Memory or it can use Acer TravelMate 4720-6182 (DDR2-667MHz) Memory but not mixed at the same time Or if you have Acer TravelMate 4720 (no suffix) Memory is the same memory as (512MB) Acer Aspire 3100 Notebook DDR2-667 Memory Upgrade (p/n ACER-512-DDR2-667-S)) Your other notebook is a Aspire 5500Z uses either 400 or 533 bus speed: Acer Aspire 5500Z Notebook (DDR2-400MHz) Memory or it can use Acer Aspire 5500Z Notebook (DDR2-533MHz) Memory again you can not mix bus speeds. According to some of the sales website the 533 or 667 models where only sold with 1 GB chips installed. So it sounds like you have 400mhz chip that won't work in the other laptop. I've been wrong before. The chips have to match bus speed or they won't work. Also the Travelmate 4720 is "discontinued" and no longer available and pulled from distribution. So you will find it hard to get service, upgrades, or parts later on. So buy what you can now. OOPs late post looks like you have it solved!!

If you still have Waranty on both machine I would go to the Acer Service and if you in Bangkok it would be at the Headoffice for Service at Rama III Road! But I'm very sure it's a compatibility Problem from the Memory. Link to comment Share on other sites More sharing options...
