Crucial Technology CT64M64S4W75 512MB 144-Pin PC133 133Mhz SODIMM SDRAM Memory

Works well. But as I said stick is labled samsung. At the time it was only thirty some bucks. 6 months later ordered from k company for less.

The ram isn't from Crucial at all. It's an Adata. I understand this ram is a little over a decade old but please don't bait and switch.As for the Ram it works fine. I ordered two sticks but only one worked without crashing my system. The one that did work speed up the decade old system but sadly it's to old to run even the lightest of android software.The ram that didn't work was returned super fast through amazon returns and I got my money back via gift card as soon as UPS picked it up a few days later.

Increased my printer workload by double. Though very surprisingly expensive for what it is. Bought and installed for my fathers HP Laserjet printer.

After receiving the memory, it was inserted into my Brother HL-5250DN printer - my printer would not power on. Returning memory.

Before I bought this item, my laptop was using 258 MB and 126 MB to run Windows XP Pro. I can't even describe how hard it was to run with that. When it ran an anti-virus scan, it wasn't worth even trying to type a document. I replaced the 126 MB with this 512 MB, and now I can even play games while my anti-virus is scanning.The most important piece of advice is, make sure this matches the needs of your computer; you can often check with the computer's manufacturer to find out what specifications you need, then shop anywhere with those numbers. That said, Crucial's part has worked perfectly for two months already, and they were highly recommended.

Works well and the price.is right. The only reason for deducting a star is that it's not Crucial memory, it's private labelled.

Seller is lying about the RAM being Crucial brand. Though the stick I received works, banking on the cachet of the Crucial name and not delivering on it is foul enough to warrant a halved rating.

The shipping was quick. The RAM worked like a charm. Would do business with them again.
