Hi Thanks for your question
For two memory modules to work together they need to be the same speed. For example PC2-4200 module will not work correctly with PC2-3200. This website provides program that will scan your RAM and tell you exactly what you need. http://www.crucial.com/uk/systemscanner/index.aspx Download the scanner and run it. Once it's finished it will show you page with results. On the bottom of this page you have information about currently installed RAM. Buy one to go with it and you should be back on your track. Good Luck

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

I want to know which memory to buy for my pc. I checked it on crucial.com and it said I could upgrade to 1gb. When I looked inside the cover I saw a 256mb memory chip but could not see how many slots it...


hello, here's a part of the spec from the hp website. It looks like you've got 256mb on board memory and one expansion memory slot in which you can fit a 1024mb card, giving you a max memory of 1280mb (1024+256).
Hope this helps!

Adding computer memory


The only thing you could do is put in a 256MB module in the slot that you have access to. Only one socket is user upgradable. The second socket is only upgradable by a Dell service center. They would have to install a second 256 module to get you to the 512MB max.

Hello, I have a Satellite A15 @129 w/756 MB RAM. I'd like to upgrade but don't know the maximum RAM stick each slot will take and don't remember if there are 2 slots or 4. Thanks, RD


The maximum RAM for this laptop can up to 1 GB DDR1 266MHz RAM and 2 memory slot available, so since u have already 756 MB RAM in your laptop, that mean 1 of your RAM stick is 512MB and another 1 is 256MB, so if u need to upgrade, u have to replace the 256MB with 512MB to make it 1GB maximum.

Adding memory to a a75-s211


How much memory did it have before you removed the 256Mb RAM?
If it had 756Mb RAM then the memory in the laptop has 512 Mb plus 256 Mb RAM modules, the 256Mb in the slot you can see and possibly 512Mb in a slot under the keyboard or soldered on the motherboard.
Therefore by removing the 256Mb and replacing with 1Gb memory module will give you a total of 1.5Gb

Sharp Actius AV18 does not recognize added 512MB PC2700 RAM. The machine still only sees 256MB. Is there something else I need to do?


I assume the laptop had originally 256Mb RAM and you put 512Mb RAM in a the spare memory slot and you expected to see 768Mb of memory, is this correct? Try removing the 256Mb memory module and insert the 512Mb memory module and see if the laptop boots up with 512Mb of RAM. If it doesn't boot up then the RAM is either incompatible or faulty. Try using RAM modules from the same manufacturer.

Acer Travelmate 529atxv states max memory as 512mb


512mb is the max memory amount this computer will accept.

Each memory slot can hold SDRAM, PC133 with a maximum of 256MB per slot. Two slots total. Hope this helps.

Memory upgrade


The M45-S169 only has one available memory slot.
(I'm confused about your post that states "M45-S265" in the head line).

  • Configured with 512MB DDR SDRAM (both memory slots may be occupied)
  • 512MB(min)/2048MB (max), 256MB on-board memory with 1 available memory slot for 256MB, 512MB, or 1024MB PC2700 DDR 333MHz SDRAM 2.5V SODIMM memory modules
You can find the complete specifications here.

Ram memory Problem?


Go to http://www.memoryx.net and run the 'Identify my computer' bit, clicking on 'Scan my system' and follow instructions.

The other thing is that if the MAX is 512, you'd want low-density memory.
