Product Description

Capacity:4 GB

DDR2 is the next generation of DDR memory. DDR2 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance. Although DDR2 modules are the same physical dimension as DDR modules, the plug-in connector configuration is different and as such DDR2 modules are not compatible with PCs requiring DDR modules, and vice-versa. PNY manufactures DDR2 memory upgrades rated at PC2-3200, PC2-4200, PC2-5300 and higher. They are compatible with desktop and notebook computers and processors including Intel`s Pentium, Celeron, Centrino, AMD`s Athlon and Sempron Socket AM2 processors, and others. PNY upgrade modules are compatible with systems from Compaq, DELL, Gateway, HP, IBM and over 5000 other systems. Boost the performance of your PC. PNY memory upgrades will prove to be an outstanding value now and in the future.

These modules are actually 800Mhz. PNY no longer makes or sells 667Mhz modules. Not all computers that require 667Mhz are compatible with 2 800Mhz modules. They refuse to down clock properly. This is especially true with a number of Core 2 Duo MacBooks. Spoke to PNY support, they flat out told me that yes, they sell 800Mhz modules in 667Mhz packaging. If you RMA a module that is 667Mhz (or supposed to be 667Mhz) they will replace it with an 800Mhz module as they no longer have any 667Mhz SODIMMs, not even for RMA replacement!

Horrible marketing department. Horrible RMA strategy.

Never buying another PNY product again!

But, at least their lead tech support person was honest. What I wrote above came directly from him!

They want me to return it to Amazon and make it Amazon's problem that PNY is selling them (and then on to consumers) mislabeled products!!!!!!!!

I bought a pair of these and doubled the 2GBs that my HP dv6500t came with. Two important things (both positive.) 1)Unlike the experience of some other users and reviewers, my Vista 32-bit system shows all 4 GBs (not the three the same OS shows with 4GBs loaded into my DELL desktop) and, more importantly, 2) The speed of the laptop is now lightening fast. It was no slouch with the 2GBs, but now - well, if you appreciate speed you'll find this very modestly priced upgrade well worth your while. No problems whatever.

This was supposed to work on my Intel Imac. It didn't. I sent it back. The good news is that Amazon processed the return without a hassle (like usual). That's why I shop at Amazon so much.

Both sticks of ram put together in 4.1 Macbook will not work, but 1 stick with stock ram will work giving you 3gb of ram.

This is packaged as 667MHz but it is intentionally deceptive. It's actually 800MHz and will not run on certain macbooks.

I don't know why there are many bad reviews on this product saying that it wont work for mac but it was so easy to instal on my late 2007 white macbook model 2, 1. For all mac users that say it doesnt work just push it in a little harder and itll work. PLUS the package that the ram is in has the Mac finder logo on it which means its mac compatible.

Ordered this memory upgrade for a Dell Inspiron 1420 laptop. Easy to install... just popped the old modules out and put the new ones in. Everything recognized fine on re-boot... but as discussed in other reviews, Windows Vista only recognized a little over 3 Gig of RAM. Big improvement in speed of laptop.

I own a 5-year-old Dell Inspiron 6000 with only 512MB RAM. I was battling between buying a new laptop PC (about $750-$1,000 with the same caliber as my Dell) or purchasing additional RAM since my geriatric laptop is still working great, albeit the slowwwwness! Besides, I am not ready to let go of my Windows XP Media Center Edition 2005 just yet, based on reading not-so-good reviews of Windows 7.

I made the mistake of buying this product in Best Buy ($44.95 + tax) just because I wanted to make sure it is the compatible one for my Dell (faster returns vs mailing it to Amazon). They were offering to install it for me for an additional $40 + tax because I told them I have never seen the insides of a computer. Long story short, technically-challenged as I am, I was able to install this intricate piece of genius in 15 minutes (including unscrewing the case of my Dell, re-screwing everything back, putting the equipment into its right place, and getting myself a glass of cold water). I was very nervous at first that it wouldn't work but when I turned the laptop on, lo and behold of all miracles, I couldn't believe that I was able to install this correctly and it is working PERFECTLY! Needless to say, I am planning to purchase my 2nd one, now through Amazon since I am positive this is the perfect fit for my Dell. Buying from Amazon is a no-brainer compared to Best Buy if you are sure of the compatibility with your computer.

I usually write PROs and CONs but I can not think of any CON to write. Oh, just make sure you hold the ends of this equipment, and that you are NOT DRUNK or else you might put it in the wrong slot :)
