Pros: These are so issue-less that it's not even funny. Good quality and good price with no issues installing or after use over time.

Cons: None

Other Thoughts: Go Phillies

Pros: I have building PCs for almost 20 years. This is some of the best memory I have ever used. The default timing is rock solid at 5-5-5-18. 5 eggs!

Cons: NONE

Pros: great all around.

Cons: one set was bad, i lost the packaging so had to RMA via A-DATA, they accepted and returned it quickly. ...and its pink. :)

Pros: Worked straight out of the package. No errors and O/Cs just fine, with my AMD Athlon 64 X2 Kuma 7550. at 2.9Ghz. This is my second set of A Data memory. And both pairs of memory have been good for my systems.

Cons: None

Other Thoughts: Thinking of buying another pair to upgrade to 8GB, Running VISTA Ultimate 64 or Windows 7 Ultimate 64.

Pros: This ram performs flawlessly. First thing I did was run it through MemTest 98 and it completed all 14 passes 100% without a single error. For those that want to know, I use this ram on a GIGABYTE GA-MA770-DS3P motherboard. So the AMD processor combined with the 770 chipset and this A-Data ram works great.

Cons: None so far...

Other Thoughts: I based my decision on purchasing this ram based on other peoples reviews here on NewEgg. I usually start it by basing it by 'most reviews' and then by 'best rating'. According to those settings G.Skill came out on top and at the time of purchase the A-Data came in second. The G.Skill was a little more, that is why I got the A-Data. The G.Skill's timings were 5-5-5-15 and the A-Data's timings were at 5-5-5-18. That was good enough for me.
I did have 2 sets of GeIL Ultra Dual Channel (1GB x 2) X2. They were the same model number except for one '=' at the end. Evidently that one small difference matters. They were identical sets but since they were bought separately they evidently had different IC chips. They worked for over eight months without any problems then BAM! Write errors and BSOD's left and right. A-Data came to the rescue.

Pros: Has cooler attached to it which has the additional purpose of protecting the chip while handling during installation and you get the feeling that the whole chip is more secure and reliable because of the cooler.

Cons: Pretty good price maybe 59.99 would have better price after all this is DDR2 and not DDR3!!I look forward to the day they start selling DDR2 for 39.99. for 4 gigs. will buy two extra ones for additional slots.

Pros: Fit in slots no problem without taking up extra space. Heat sinks look nice.

Cons: None

Other Thoughts: I don't have a screaming machine, but this 4GB was for a Vista machine that is running MCE. Its doing the job just fine--no complaints here. OS recognized it right away, and that's what I wanted. Overall great deal.

Pros: A-DATA makes great RAM BUT....

Cons: one of these two sticks was DOA and computer would not boot

Other Thoughts: PIA to RMA and have to pay to ship it back but what are ya gonna do... Newegg has great RMA service so that's a plus!

Pros: Worked right out of the box, no problems. Windows 7 recognizes the 4gb of ram. Pc runs faster and smoother than ive ever been accustomed to.

Cons: Well, I'm running 32bit, and while it recognizes 4gb, it says only 2.75 are available, wgy is that?

Other Thoughts: Great sticks of RAM, I recommend them.

Pros: This RAM is excellent for office or enthusiast use. First off, the default voltage of this RAM is 1.8v making it compatible with every motherboard out there (at least the 4 or 5 different brands I have installed this RAM in. Stay away from the more expensive, high-volt garbage as you can achieve the same timings and great clock speeds by just tweaking the RAM settings of these sticks in BIOS. In my personal rig, I'm running 8GB (4X2GB) of this RAM at 840MHz with timings 5-5-5-12-3. I have successfully ran these sticks at 900MHz/2.16v for two hours under Windows 7. No problems, no BSOD just good old fashion heat and lots of it. The rig I'm running this in is an X38 Asus Rampage Formula (latest BIOS) coupled with a 2.4GHz Q6600 running at 3.4GHz without a hitch. This box is used for gaming, surfing the net and schoolwork.

Cons: None to mention.

Other Thoughts: This RAM has become the defacto standard for RAM that I purchase for DDR2 boxes. We even purchase this RAM for our office Dell equipment (Optiplex 745s mostly). I have not once had a problem or a failed or failing stick of RAM. Buy this stuff and you won't be disappointed.
