5.0 out of 5 stars Best RAM money can buy!
Reviewed in the United States on March 3, 2010

I originally order this to max-out my RAM capacity because I required more speed with all of the applications running in the background, and the mere fact that Windows 7 (like all higher versions of Windows) requires a lot of memory. Looking at the prices for other 4GB PC2-6400 DDR2 800Mhz SODIMM kits made purchasing this particular 4GB kit easy. I saved an additional $10-$50 dollars compared to the other guys, and am happy with its performance so far. I do however, wished Microsoft would allow its operating systems to allow users to use the full 4GB up-front instead of allocating it for memory needs later on. I loved the shipping speed (although I bought from [...], and [...] being within the same state as me probably had to do with the quickness of the delivery), and the overall installation of the RAM was as easy as lighting candles...yes, an 8 year shouldn't install this...preferably an adult. I would highly recommend this kit to those looking to top-off their memory, or increase the memory from the store pre-installed memory kits. Good Stuff!

1.0 out of 5 stars Doesn't work at all on iMac 2.4 GHz, 24", mid-2007
Reviewed in the United States on December 12, 2008

I bought the upgrade for my iMac (24", core 2 duo 2.4GHz) and it simply doesn't work.
When I turn the iMac on, I hear the fan starting and then nothing. Tried to swap modules, plug/ unplug, etc. with no benefit

I searched the web and I found other people with the same issue and some other who stated they are using it successfully.

One guy interestingly said the two 2GB modules do not work, but if he keep the original 1GB module in first slot and add one of the 2 GB in second slot it works fine.
I tried it and, guess what? It is true. It works that way (1GB in first slot and 2GB in second slot). Problem is that I only have 3GB this way.

I don't know what is the problem but I saw some Apple apps note saying that some recent FW (I assume EFI) updates check the memory SPD and disable memory if it doesn;t meet Apple specs. My guess is that as long as the first slot is Apple approved it will enable the second, but if they are both not compliant with Apple directions it won't start.

This would also justify why some people have good experience and some bad: it may relate to which FW version they have and when they did it.

Be careful before buying.

3.0 out of 5 stars Not a positive experience on my Dell XPS M1710
Reviewed in the United States on July 18, 2009

I bought these to upgrade my Dell XPS M1710 memory from 2 GB to 4 GB.

The good:
1. Excellent value for money (provided it works for you)

Bad:
1. It causes my Windows OS to crash unexpectedly.
2. It also causes my Ubuntu 9.04 to freeze. I have a dual boot system and both OSes work fine with the original 2 GB memory.
3. These memory cards also fail the Dell diagnostic test (that comes with the BIOS) in my laptop. In particular, the walking 1's and 0's test fails.

4.0 out of 5 stars Great memory upgrade until I needed to make a warranty claim

Straightforward memory upgrade, but one of the modules failed after two years. Unfortunately, the manufacturer had been acquired by another company. They did not honor the warranty on this memory.

Unless you need gaming memory modules with faster timings, go with Crucial (Micron) or Kingston. Both have excellent warranties and have been in business for many years. They should be around in case you need to make a warranty claim.

5.0 out of 5 stars Excellent Boost for iMac at a Good Price
Reviewed in the United States on August 3, 2008

I recently switched from Windows to Mac at home. I've been seriously involved with just about every aspect of software and hardware development for the Wintel platform since its inception, and I'm an expert on everything from system assembly and setup to support to large enterprise software development. I told you that to tell you this...after having used a Mac for a month, I'll never go back.

This memory upgrade is an excellent option for the newer iMacs (May 08 version). I bought the iMac with its standard 2GB of memory and bought this kit to upgrade to 4GB. Excellent performance improvement for less than Apple would have charged for the upgraded.

IMPORTANT NOTE: The iMac 2GB comes with 2 1GB memory chips--that totally fills the slots. If you want to upgrade to 4GB, you can't just buy a single 2GB chip and put it in...you have to take out the memory that came with it and put the 2 new chips in. Fortunately, it's a very simple process (just requires a moderately small Phillips screwdriver), and there are pictures showing how to do it in the Mac manuals and printed on the memory door itself. *Way* easier than doing it on a PC.

I highly recommend this upgrade.

5.0 out of 5 stars Excellent Memory, Highly Recommended Upgrade for Laptops!
Reviewed in the United States on March 18, 2010

This kit is a great addition for a new laptop purchase. If your laptop can handle this memory, you should buy a kit such as this and upgrade immediately. Trust me, 4 GB is much better than having 2 or 3 GB. With 4, my system runs a lot smoother and I can run many more programs in parallel.

Installation of these modules is very easy, if you're having trouble or are concerned about how to do an install, just Google instructions for installing memory in your specific system. Oh, and do not buy memory from your laptop vendors, they sell it at a premium, and its the same RAM as you can buy yourself, at much cheaper prices.

All in all, this was a great kit, very speedy and I am extremely happy with my purchase.

1.0 out of 5 stars Caused my system to crash
Reviewed in the United States on May 12, 2009

I will admit that I had not checked the compatibility of this product with my computer before ordering, so it is possible that it was just incompatible. But when installed my computer would not boot and I got the dreaded blue screen of death with a message that advised that a hardware problem was causing a fatal error and that any newly installed hardware should be removed and then try to reboot. When I put the old memory back in it worked fine. Tried the new memory again and, not surprisingly, got the same message. Amazon's return policy was great and they promptly refunded my $. BTW, the first time Amazon shipped this product all I got was an empty box, the shipping box had obviously been opened, the contents removed and the box re-sealed. When I contacted Amazon they were great and promptly sent a replacement and upgraded the shipping at no charge. Product one star. Amazon's service 5 stars.
