Acer t180 ud360a memory

HI. Added 2 x 1 gig dimms to system that came with 2 x 512mb's. with all 4 memory slots filled the pc will not boot up. Just beeps. When I remove any 1 module everything works fine in any combination in any three slots. Memtest says all modules are good. How do I access the BIOS on this machine? The spec sheet says this came with pc2-4200 memory, it came out of the box new with pc2-5300, is this common.
Thanks for any help.

    Thanks for the imput. I checked the BIOS update you refer to, R01-B1, with acer issue resolution information this update refers to DDR2-533 issues and does not refer directly to my issue. My pc came new in the box with DDR2-667. Have you used this update for similar issues, have you installed this update on any 667 equipped computers? I very much appreciate your help, but could you tell me the basis for you recomendation?

    Thanks again for your help.

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:

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 have recently upgraded my brothers Acer T180 computer with approved crucial 2 x 1GB ram ddr2 PC2-5300 667 NON ECC UNBUFFERED CL5 which was scanned by the crucial website and purchased from them. When the...

Some motherboards are only upgradable to their allotted amount that board may only handle up to 2 gigs of RAM which is a shame. But this is the way it is. That is why I always check the board memory capacity before I buy computer boards or RAM for them. The beeps indicate error on the slots for the RAM that is why you can start up when you remove ram one at a time and replace. So use the allotted amount of RAM for that board specification or get another mother board that can handle more than 2 gigs of RAM. Sorry for the loss. Thanks for using FixYa! John

Gateway desktop fx 7026 memory issue, has 4 slots came with( 2 )2 gb sticks = 4 gigs it came with. when i add 2 extra gig it doesnt recognize.

the specs i read says 8 gig is the max. here is what it says for RAM
  • Installed Size 4.0 GB / 8.0 GB (max)
  • Technology DDR2 SDRAM
  • Memory Speed 667.0 MHz
  • Form Factor DIMM 240-pin
  • Features Dual channel memory architecture
  • Configuration Features 2 x 2 GB

check to make sure you have added the right type of memory. also look at your user manual. it should tell you where and how to place the added sticks. sometimes they have to be added in pairs or have to be in specific slots. also if you dont have the manual it is on the gateway site. you should type in your model and serial number and get all the info you need.

RAM error

Populating the memory according to the following guidelines resolves this POST error:
  • DIMMs must be configured in identical pairs.
  • The system will not boot properly if multiple DIMMs of varying density or type are installed in the system.
  • The Entry model servers come with a single 512 MB DIMM. If additional DIMMs are to be added to the existing 512MB DIMM, then another 512 MB DIMM has to be added along with the new pair of DIMMs, or it has to be removed when adding the next pair.
  • Valid DIMM pair combinations use slots 1/5 (Bank A), slots 2/6 (Bank B), slots 3/7 (Bank C), and slots 4/8 (Bank D).
  • Up to 16 GB of memory are supported on the Dual-Core 5000, and 5100 series
  • Up to 32 GB of memory are supported on the Dual-Core 5200 series, Quad-Core 5300, and 5400 series
  • FBDIMMs must be installed in pairs unless operating in single-FBDIMM mode. The server supports single-FBDIMM mode only in FBDIMM slot 1A. FBDIMMs must be installed in sequential order, beginning with bank A.

Acer Aspire T-180 Memory Upgrade question

Hello, You might be able to add 2GB more. 1GB per slot. You need to get the model # off your motherboard and verify what the maximum amount of memory it will support. 1GB per slot would be 4GB total but some Operating systems will only support 3GB. So some might be wasted if that is the case. You would need to use the same memory type. So if existing is PC2-4300, use the same. Hope this helps.
