Pros: I bought two of these kits - 4 modules totaling 8GB of ram, and installed them in an ASUS M4A88TD-V EVO/USB3 AM3 AMD 880G HDMI SATA 6Gb/s USB 3.0 Motherboard. The modules were recognized and automatically set to run at 1333MHz. Didn't need to set voltages or anything. I ran Memtest86+ v4 and tested for 2 passes, and they're perfect.

Cons: None.

Pros: Really fast and really inexpensive. SPD properly configures modules with all advertised specs, including timings and voltage.

Cons: One module in the first pair I received was bad. Unfortunately, if you purchase as a pair you have to return as a pair, so my new home server was out of commission for over a week while waiting for a replacement. Replacement modules both worked great, passing rigorous memtest86 testing without errors.

Overall Review: Cost me an extra ~$5 and lots of waiting because of the return. Newegg made it up to me though, as there was a free 4GB flash drive surprise gift with the second pair. How cool is that?

Pros: Installed in a HP 8200 Elite CMT business desktop. Booted right up, and all 16 GB recognized in addition to the 2 x 8 GB Mushkin modules I already had in there. Now at 32 GB. Memory Windows Experience Index (WEI) prior to installation of the Mushkin memory was 7.6. After installation and WEI refreshed, I am happy to report it is still at 7.6.

Cons: None

Overall Review: The package was easy to open compared to some other brands where you have to use a razor and carefully slit the package open, and then try to pop the memory out of the plastic retainers. Probably more memory than I will ever need, but at this price, I felt this was the time to max the PC's memory out. Just take a look at how high the prices of notebook DDR2 PC-6400 4 GB memory modules are now, compared to what they were a year ago! NewEgg is the best!

Pros: Works great with Core i3-530, which I got from NewEgg at the same time as the memory. In fact it exceeds rated specs, can run faster and/or with tighter timings with very little voltage increase.

Cons: All mem prices appear to be dropping, so it could be less if you can wait? I'd give it 5 eggs, but rarely if ever rate anything at 100%, so consider the 4 eggs as a pro, not a con.

Overall Review: Already reviewed, then noticed previous reviewer indicating an issue with this memory and Core i3, but that's false. I'm posting this so people will know there's no problem, my i3-530 is >4GHz with this Mushkin OC'd to 1456 (1.55v) in a Gigabyte H55M-SV2, stable, fast & quiet.

Pros: Used this in almost a dozen builds...had one pair DOA. For the price, and thanks to Newegg's RMA policy I have forgiven Mushkin of this error. Besides, the working sets are great, and well priced.

Cons: Personally, a close to 10% fail rate. Not enough samples to be a valid statistic by any means, but makes me raise an eyebrow.

Overall Review: This will continue to be my staple DDR3 1333 memory, though any more failures would be a dealbreaker for me.

Pros: Recognized just fine by mobo. Did not catch on fire. I had a new one shipped to me in a week. This one was physically taller, too.

Cons: The replacement had the exact same problems. And now I can't file another return. Why.

Overall Review: I don't know why I strayed from GSKILL. Never again.

Pros: 1. It's a 4GiB stick of DDR3 for $25 (ca. July 2017) 2. It functions perfectly at the advertised rate of 1333MHz 3. It works in triple-channel with 2 other 4GB PC3 10666 modules

Cons: The stick I got had blue PCB, and it was half the height of the 2-pack of Mushkin Enhanced Essentials 4GB PC3-10666 I'd previously ordered. (It works fine, it just triggers my OCD whenever I open my computer and see the one odd-looking RAM stick.)

Pros: If you need DDR3 Memory at a affordable price this is it! Best GB for your $$$ Don't get another brand just because of brand! This works great!

Cons: None! If you need certain speed and timing this is it!

Overall Review: I would recommend this to anyone this is a great memory module for what you need! I run a small business and install these in all of our basic entry line computers!
