Question about Toshiba Satellite A25-S2792 Notebook

2 Answers

I have a toshiba a25-s279. It had two slots of 256mb of ram. I took out the A slot and replaced it with 512mb of ram. I'm running 768 total. When I right click on my computer and look at the properties it only shows 480mb of ram. Can't get the 768 to run.

    I'm not very computer savy, obviously. I did do some research and it showed that I could run this ram (Ultra 512MB 200 -PIN Sodimm 64Mx64 DDRPC2100 NON-ECC PBF).



    The system I'm running is Microsoft Windows XP Home Edition Version 2002 Service Pack 2

    Toshiba Satellite Intel[R] Pentium [R] 4CPU 2.80GHz, 2.79GHz, 480MB of RAM

    Also, try the 512 MB. in a slot by itself to see if the unit sees it. It may see 512 MB minus the amount used for video, usually 32 MB.

    If it sees the 512 MB. then install one of the 256 MB.

    Do you have the right memory? You need:

    512MB PC2100 DDR 266MHz SODIMM

    Not all ram will be showing as some is reserved by windows for the video card etc - what os are you using.

    Do you see the full ram amount when bios posts?

    You shouldnt really mix two different types of ram together.

The other ram which you had is not compatible with ur new 512, u must replace (B slot) with another 512 ram and it will surely run upto 1 gig. and its much better that way.

Change the order of the RAM, place the 512 where the 256 is and replace the 256 in the slot that the 512 was in.

    I see above. Have you reversed the position of the RAM sticks?

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!

Memory won't add on a Gigabyte GA-6VEML


Hi,
this will be dependant on the bios version. or if the 2 ram modules are identical or not. if they,re a matched pair. the motherboard may not like or run in dual-channel mode. sometimes adjustable in the systems bios. the other suggestion, is to try 1 stick of ram, in each slot individually. This will eliminate A Faulty Slot. Failing any Of The Above. try 2 x 256mb sticks, And Obtain The Latest Bios Update from The Manufacturers Website.

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.

Total amount of RAM not recognized by computer


are the modules the same specs? you may have some incompatibality between them. the board may be reading the ram right it may be you have four 256 sticks instead of 2 of each. read the motherboard manual it might shed some light here.

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

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.

Memory upgrade


It looks like the A25 will only hold 1g of PC2100, which is really plenty, unless you're a serious gamer or into graphic arts and need an extreme high definition video. Here's a link to the memory configurator that I use in order to find the proper memory, max held, and the chipset. You might double check to be sure I looked up the right machine. If it is the right machine, I suggest two 512mb chips. Sometimes you can't run one 1g chip because the slots are designed to only hold a certain amount, and if they will hold the 1g chip, sometime the machine doesn't run properly. It wants to use both slots accordingly, running only one creates conflicts. This should help in boosting your RAM.

IBM ThinkPad T40 2GB Max RAM


The T40 has two ram slots, you can put a 1g chip in each totaling 2g. If the chip will remove, then it is changeable. Vista needs a minimum of 256 to run, so, when you change BOTH chips to equal 2g it will probably read 1.744g, or it may read the full 2g. If it only reads 1g, then the second slot under keyboard may have malfunctioned. It could also be that the 256 chip is bad and your really only running 512 now. With all that said, in order to achieve 2g, you will need to put a 1g chip in each slot.

Problem with amount of RAM.


maybe your video card uses 128mb shared memory so 128 for video plus 640 reading equals 768.
