Pros: It works on older computer that needed a little more memory for win 10

Cons: No heat spreader.

Overall Review: Basically, an old computer in living room connected to TV / Internet used rarely. Computer had Win 7 and I downgraded to Win 10; needed a little more RAM for operating system. I like GSkill and for last 10 years is only RAM I buy. Choices on DDR2 are limited.

Pros: Acceptable performance while it worked

Cons: Computer started acting strangely and eventually wouldn't boot up after about 6 months of use. When this memory was removed, the computer resumed working as normal.

Pros: None

Cons: Will not boot took a while to figure out, I pulled memory inserted old no problem will return this is a new build again same type memory the motherboard is ASRock G41C-GS R2.0 LGA 775 Intel G41 + ICH7 Intel Motherboard, as far as I can tell from specs it should run this ram, it runs with old ram same specs as far as I can tell, anyways will return.

Pros: -Cheaper than the heatsinked version

Cons: -Not as good looking as the heatsinked version (but I don't care, my case has no window)

Overall Review: I was able to match it with an HyperX KHX6400D2/2G stick of RAM in a dual channel pair (same speed, timing and number of chips) on an Intel DG965SS motherboard.

Pros: none

Cons: Out of 4 modules, none would allow computer to POST. Ordered 4 sticks of 2Gb to replace 2 sticks of 1GB. Tried in two different computers running same spec Corsair memory, neither would run this memory. If installed along with working memory, pc would recognize the memory, but would not map it. Awaiting RMA

Overall Review: Buyer beware

Pros: It works to this day as expected.

Cons: none

Pros: Full compatible with existing memory

Cons: nothing

Pros: It works right out of the package no tweeking or adjusting of anything required. It is Gskill and that says it is a quality memory product. It is about the fastest DDR2 still available and the size makes is a good value for the money over buying two seperate 1Gb sticks. The timings are very good as well at 5-5-5-15 most others DDR2 800 are timed at 6 or higher.

Cons: It didn't come with a case badge. Also no heat spreader but hey it is the value level of their RAM

Overall Review: I bought this stick to add into an older machine to give it a fw months more life. The memory that I already have in there is Gskill DDR2 1066 5-5-5-15 (2 1Gb sticks). This slotted right in and the timing of the older memory matched up to it with no difficulty because the timings were identical. It makes my machine perform like it did a few years ago and for under 30 bucks. The 1066 that was in the machine when I originally built it has never given me any issues and it is now approx. 6 1/2 years old. Not only does Gskill make high quality RAM they make it to last as long as you can keep the platform it is installed in working.

Every machine I have rebuilt for family and friends now runs Gskill RAM exclusively and I have never had any issues with their RAM. I know it is always possible to get a bad stick occasionaly but so far I haven't gotten one from Gskill.

Also Newegg got it here in a timely manner and it was in good condition even though it was sent in only a padded mailer. For RAM I wish they would use a small box just to lessen the possibility of it getting bent or broken in shipment.
