How to upgrade memory what is the best memory for my laptop toshiba satelite 1800


Hi,

Samsung original 256mb sdram PC133 144in sodimm 8chip 16x16 configuration. . Compatible memory for Satellite 1800-S253

That machine will on take a maximum of 512mb, so you could get 2 256mb to max out the memory. Samsung is the best for that machine, and they run around $20.00 per 256mb.

Thanks Mark

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.

Compaq Presario Notebook V3000T I replaced the 2-256mb memory cards with 2-1g memory cards. System boots up but only reads 1024mb?


Thanks to Microsoft Knowledge Base for help with my answer:

First, find out what the maximum amount of memory is. This is generally listed by most of the manufacturers. This will let you know what upgrade potential the system has. Next, determine how the memory configuration is when you buy the system. For example, a laptop that has 2GB of memory can be configured as either a single 2GB module or two 1GB modules. The single memory module allows for better upgrade potential because by adding another module you are gaining more memory without sacrificing any current memory. Upgrading the two module situation with a 2GB upgrade would result in the loss of one 1GB module and a memory total of 3GB.

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

HP ze5470us memory upgrade not fully recognized


Hi there,

I am almost sure that you, by accident of course, switched the memory blocs, so that you have put in one 256MB and one 512MB.

Have a look at the once you have on the table.

Installing Memory


Hi

Yes, you can replace/upgrate the memory module under the keyboard.

Before you proceed, note that Dell Inspiron 2650 uses DDR200 3.3V SODIMM modules. Also, memory module capacities supported are 128MB and 256MB with a Maximum memory of 512MB. If the current memory installed is 128MB, you need to order 2x 256MB modules to replace/upgrade both memory slots. If the installed capacity is 256MB, you just need another 256MB for the slot underneath the laptop.

Check "Removing the Keyboard" for guide removing the keyboard to access the 2nd memory slot.

Read "Preparing to Work Inside the Computer" before committing to the above procedure.

Let me know how you get on.
