Memory Review |
| Comments: |
The product was as ordered and delivered faster than expected.
The only issue I had was with Win7 32 Bit which would not recognize all the memory on my HP EliteBook 6930p. I installed the 64 Bit version and everything is now working. No issues with memory to date. |

Memory packs finally installed, after 2 months.
Very nice results, no problems detected so far.
Discovered that the brand (hynix) was the same as the ones already installed in my computer.
Thank you very much! |

I have only had this DDRAM for my laptop for a few weeks but so far so good. The price was decent, came with free shipping and it definitely helps speed up my computer with no faults. This was a first time purchase for me from PRO Memory Upgrade so I have my fingers crossed that I have no issues. |

| Comments: |
Recieved 4 days after order with Priority Shipping. Was pleased with secure and safe packaging. Easy to install as is all memory from my prevoius experience. Works great, and showed up on system properties. My Microsoft score went up 1.5 points. Now all I need is the bigger 750GB 7200rpm 2.5" Sata Hard drive, and my new HP Tablet will be pinmped out. Might I had I saved $75 buying my memory here as opposed to anywhere I looked online, seriosly! That $75 bought me the new speakers I wanted, and I did not sacrifice on quality. I am very pleased with my purchase, will order from again on my next laptop upgrade! Thanks ProMemory Upgrade! |

Bought 2 of them |
| Comments: |
I bought 1 4gb ram cards thinking that my laptop had one already. I was wrong. I replaced one of the 2gb cards with the 4gb and my laptop accepted it without even the slightest issue, I noticed a significant improvement in speed and went ahead and bought another 4gb card since my system allows for 8gb max ram. It is awesome. I upgraded the hard drive as well and even though there were a few issues in that arena, the expanded ram made everything perfect. |

Purchasing and installation couldn't have been easier. The price and service was great and the delivery to New Zeland was quick. The memory modules were high quality and greatly appreciated by Windows 7! I highly recommend ProMemoryUpgrade as a dealer and the memory they sell. |

I had 2x2GB RAM on HP Pavilion DV4, and I upgraded one of them with 4GB. It seems to me that it is working a little bit better, smoother, and faster than before. I am satisfied with my upgrade. I do not think I need to upgrade for 8GB, It is expensive. I would deal with it until I save more and buy a stronger computer. |

Memory Upgrade |
| Comments: |
My Toshiba notebook came with 6GB of DDR2 800MHz, but I felt it needed 8GB so I ordered A 4GB module to replace the 2GB module. This now gives me 8GB total memory, that works great.
I made my purchase from PRO MEMORY UPGRADE, got promt service, followed instructions and am happy with my choice. No problems with purchase or intallation. Didn't have contact customer service, everything went smothely. |

Memory 4GB DIMM |
| Comments: |
I purchased this memory to enhance the memory of my HP Pavilion Laptop. This Laptop has a normal memory max of 2Gb but with its Dual Core AMD processor and Vista 64 bit program it will address 8GB and a consequental increase in processing power/ running several programs at one time.
I have also tried it in my MSI (HDMI) Which has a dual core Intel processor and it works wellalso allowing 8 GB of memory to be addressed in it's two memory slots (like the HP) |
