Need to upgrade a bunch of older laptops? This is a great deal – you get ten separate 1GB sticks of DDR1 laptop RAM, adding up to a total of 10GB. Each module is PC-2700 (that's DDR-333), runs at 333MHz, and uses the standard 200-pin SO-DIMM form factor. Voltage is 2.5V, and it's non-ECC buffered memory, which is typical for consumer laptops. This is an unbranded/generic lot, but it comes with a solid lifetime warranty, which is awesome for peace of mind. Perfect if you're refurbishing older systems, running a repair shop, or have several machines from the early-to-mid 2000s that need a memory boost. They're brand new in packaging, so you know they haven't been pulled from old systems. Just make sure your laptops use DDR1 (not DDR2 or DDR3) and have 200-pin slots. This bulk pack saves you from buying individual sticks and is a cost-effective way to max out the RAM on compatible machines. Get those old laptops running smoother for basic tasks!
