I'm trying to revive an old travelMate 518tx and I'm currently in the process of searching for bottlenecks. I want to check if the RAM sticks are still functional or not, but they're both very old, and I'm unsure how I can test them.

Is there a way to either insert them into my computer or to see if they work?

Picture of the RAM sticks (pencil for scale):

    «pencil for scale):» that begs the question of how long is the pencil?

Those look like 144-pin SO-DIMM memory modules. It's a very old memory technology. If the computer you pulled them from isn't working, your best bet is to find a known-working laptop of about the same age that takes that type of memory, install the RAM sticks one at a time, and run MemTest86+ from a boot CD or floppy to check the memory.

  • @StephenKitt Memory technology ages quickly. That's why you (probably!) own a >1TiB drive, for example.

  • @Bálint I misread the Wikipedia article, the JEDEC standard does indeed date back to 1999. SO-DIMM refers to the physical format; they use SDRAM. Oct 13 '16 at 8:55
  • @Bálint um? That's like pointing to a loaf of bread and saying "that's not a loaf, it's bread." What you have is SDRAM (post-EDO, pre-DDR), in SO-DIMM format.

  • "It's a very old memory technology" ...Now I feel old. My notebook still runs on these... (:
