Kingston2GB 667MHz DDR2 Non-ECC CL5 SODIMM Notebook Memory (Pack of 2, 1Gb Each) (KVR667D2K2SO/2GR)

I'm an I.T. guy, and have lots of older equipment around. I ordered this to add to get a x60 tablet/laptop to run windows 8, with an SDD hard drive, at a decent speed.Installed w/o any issues, but depending on what you are working with, your mileage will vary, so do your research before taking ona job like this.The touchscreen tablet/laptop runs much snappier, web browsing, basic programs load without any lag or issues. I'm not loadingaudocad or anything graphic intensive, but for basic computer use, this works just fine.I would recommend this to add some speed to an older system.

This was very easy to install in my Dell Inspiron 1525 and Vista recognized the new RAM with no problem. I upgraded from 2gb to 4gb but the 32-bit system can only utilize 3.xx of the RAM. I noticed a significant increase in speed when opening and saving Office docs and I think streaming video is a little faster, but that's about it. Overall, I'm happy with the product and feel it was well worth the price I paid, as Best Buy offers the same RAM for 2.5 times the price.

Works great in my Lenovo SL500. Popped right in, less than 5 min install and my laptop was enjoying its new 4 Gb extension from 1Gb. Very happy with my purchase.____Edit as of Feb 14, 2009.I bought this memory sometime mid-December '08, and it's been working fine. I'm editing my review, because I see people here complaining about their OS not recognizing full 4 GB of this memory.Answer:If your OS - Vista, Win XP, Linux, etc - is 32 bit you will *NOT* be using full 4 GB, but something around 3.2 GB due to OS limitations itself, (for more info check this Wikipedia's link: [...].In other words you need to have a 64 bit OS - Vista 64 bit, Win XP 64 bit, Linux 64 bit, etc - installed in your laptop.I have Linux 64 bit OS (Ubuntu) installed and it uses full 4 GB capacity. No issues. I can run five virtual machines (OS-s) at a time with those 4 GB. For people that use virtual applications, they know what I'm talking about.____Edit as Feb 25, 2012.Best forty bucks spent. This memory is still rocking, never had any issues whatsoever and it's made using my laptop a pleasure. Highly recommend.

This went in my Early 08 MacBook 13" (white) easily. Interestinly, these Kingston modules are a bit of an upgrade of quality as well as quantity. WHen I removed the Apple installed 1GB modules, they turned out to be essentially generic RAM, a brand I've not heard of in 17 years of Mac-ing it (and 5 PowerBooks, a G4 Cube, an original iMac, a PowerMac 8500, a Quadra 950, and a IIci, all I still have and all still [mostly] work). So I am very happy to have 4GB of Kingston RAM in my little friend. Install was a breeze, and operation and compatibility is full after over a month and all apps and tasks run and done. I paid [...] bucks plus tax (shipped free) and can hardly believe the good deal I got. With a lifetime waranty from Kingston, why would you pay 55 or 70 for the someone else's 4 gigs? Just great! Should work great in any MB, MBP, or iMac specced to use PC2-5300 DDR2 SODIMMs (NOT for the new UniBody Aluminum MacBook, that uses PC2-8400!).UPDATE 3/10: still running strong for over a year, not the slightest problem or issue to date. Still strongly recommend, though I see the price has more than doubled (I paid $37.93)

The product itself is fine. It was very easy to install.However it did not meet my personal need. I was informed that because my computer was operating on 32-bit it would only recognize max of 3GB of RAM. To use the full 4GB, I would need to have the 64-bit vista. I don't blame the manufacturer of this product for that, I blame myself for not finding out prior to purchasing this.The increase in performance to my computer has been minimal.

There are only brands of memory I will purchase, Kingston and G.Skill. As a computer repair professional, I have tried them all. Every time I would try a bargain brand I would have a failure. I have been to the Kingston plant in California. Kingston actually put me in the Four Seasons Hotel, and wined and dined me for several days, while giving me the full tour of their facilities. I was very impressed that they thoroughly test EVERY component before it ships. Their level of quality and attention to detail is unmatched. Sure, you may pay a little more for it, but it's worth it! Especially when you are working on a customer's computer and don't have time to order another part. The additional time and expense required to purchase replacements and return defective items far offsets the little extra you'll pay for quality components. Kingston RAM works every time, all the time, and pretty much forever! I have never had a failure.

Not being technologically inclined, I didn't realize that my Toshiba Satellite A215-S4697 was running so slowly because it didn't have enough memory. It came with 1GB RAM, and it never occurred to me that I should increase it. Meanwhile, the laptop was taking forever to boot up, Web surfing had become frustratingly tedious, and I was out of patience. I had started to convince myself that if I dumped Windows Vista for Windows 7 all would be well, until my brother asked how much RAM I had. When I told him, he said, "Well, that's your problem. You need to upgrade -- get 4GB."After doing some research to find out which memory would be compatible, I decided on the Kingston ValueRAM 4GB Kit (2x2GB Modules, 667MHz PC2-5300 DDR2). Less expensive than anything I found at Worst Buy and other brick-and-mortar stores, and delivery was super-fast. It took non-techie me all of five minutes to install, and I couldn't be happier with the results. No more 20-minute boot-up. No more hanging. I may yet upgrade to Windows 7, but for now Vista's running much more smoothly. It's like I have a brand-new computer!
