instruction bookk should have pointed out you have to remove old memory first before installing 2 gb memory ... this becomes the total memory not an additive amt ... however, makes the computer really fast compared to original performance and all for under $40 |

Pro Memory is a great company and has a user friendly website but it seemed like USPS could beat the price and delivery time for shipping. It comes in a big box compared to the memory chip. Your company might want to find a better delivery system. |

Notebook Memory Upgrade |
| Comments: |
Very pleased with the product. Works as advertised. A snap (actually two snaps) to install. Once laptop was off and unplugged, simply removed access panel, opened retaining clips (first snap) for old memory card (old card popped up and was easily removed), inserted new memory (second snap), replaced access panel and turned on. Clean restart with much improved performance.
Also, very pleased with PRO. Competitive price, shipped and delivered as promised. Good experience overall. Will recommend to others. |

All the purchasing and delivery process went on smoothly. In fact I order another one yesterday to complete the 2 GB my machine can handle.
I'm glad I went with PRO Memory. |

This Memory was lacking in some way. Also these are not as advertised. The RAM didn't perform anywhere near as well as RAM I eventually bought from Certified MAC techs. For some reason the Memory forced the finder to restart every time I tried to log onto an XServe, replaced the RAM and no problems. I say go for the real deal not bargain chips. |

| Comments: |
When I tried to install the memory that you sent, it did not work. Electricity appeared to be passing through but the Sony Vaio - FE550G did not boot up.The three small sights just above the keyboard lit up and stayed lit, but nothing more happened.
Maybe you sent me the wrong modules for my laptop.
Should I send these back so that you can send me two new ones?

I had to dig out the manual to figure out half of the OEM memory was under the keyboard, other half on the bottom. This memory worked great thought once I figured everything out. Really improved Wndows XP performance too! I went from 512Mb to 2.0 Gb, and mostly just surf, play videos, etc on that machine.
Great upgrade, easy to figure out what to buy with their guides, and in the end all worked GREAT! |
