Pros: Works perfectly without issue, and cpu-z shows it working exactly as advertised.

Cons: Didn't really increase my battery life like I'd hoped it would.

Overall Review: I bought this set as an upgrade for the 6GB my Acer V5-571P-6642 came with. The laptop has a 4-cell battery and only had about a 4-hour lifespan, so I bought this ram with the hope it would increase that by a bit. It DID increase it to 4 hours and 20 minutes, which IS an increase, but I was hoping for a little more. I'd also like to note that the upgrade from 6GB to 8GB was almost entirely unnoticeable in my experience. Given the option to do it again, I think I would've just stuck with what I had. However, if you have 2-4 gigs it's definitely worth it.

Pros: Great timings of 8-8-8 for 1333 or 9-9-9 for 1600. Will increase your windows experience score mine went from 5.9 to 7.1 my speed for my memory went from 8GBs to 9.5GBs with maxxmem test. The thing is that the speed is something you will get from any high performance ram but what is truly unique to this ram is that you will have better battery life because of its reduced voltage. I see about 30min longer on what was a 3hr battery. Also if your computer has an integrated graphics not radeon or gforce mobile then your ram is your video cards ram so therefore this will increase your video performance as well.

Cons: Any PC/CPU can reject certain RAM DIMMs it has become very common and because of this manufacturers have had to make huge compatibility logs. What this means is it may be possible that this ram is unstable in your PC so I recommend that you install it immediately upon receiving it. As soon as you install it I recommend downloading prime95 and running a blend test for 4-24HRs just a few moments will likely tell you the reality but it is best to test longer. You may want to test before as well to ensure your system was stable to begin with.

Overall Review: It seems that people are a lil in the dark about how RAM works and what to expect. If your system does not report this ram as being 1600MHz don't worry you didn't do anything wrong and there is nothing for you to do to fix this problem. You Laptop has a max speed it can run usually it is the same or 1 step higher than what was included with your system. For most MAC users it must be a specific speed since the ram will always run at the max speed even if the computer is not capable of that speed. Also I see a lot of my ram only performs at 500 or 666 or 800MHz which is not what I expected I don't know how to get to 1000, 1333 or 1600 well if you are paying attention those speeds are all half of the intended speed. Which brings us to the name of the ram DDR Double Data Rate your ram may be reported as being 1/2 its actual speed. Also if you can only run 1333 not 1600 you will be given a nice lil bump in timings from 9-9-9 to 8-8-8 so its not the big of a disadvantage.

Pros: Works perfectly at 1600MHz in a late-2011 MacBook Pro (Core i7 2.4GHz). Had read elsewhere that the MacBook would not recognize the 1600MHz CAS9 settings and would run this at 1333MHz, but that was not the case for me. The system recognized it immediately at 1600 and has been quite stable. Also like the lower voltage for a laptop.

Cons: None.

Overall Review: None.

Pros: Works fine in Toshiba Satellite R845-S80 BIOS runs them at DDR3-1330 with CAS 8-8-8-20-1T (no user choice, as typical) WEI for RAM improved from 5.9 to 7.3 OK with Prime95 and 8 passes Memtest86+ 4.20 (each pass takes about 1:24 for 16GB)

Cons: none so far

Pros: All the ram specs posted seem accurate, except for the voltage, according to CPU-Z it's 1.28V instead of 1.35V which is actually really awesome. In fact my battery life has been increased by half an hour in spite of the fact that I went from 6gb of ram at 1333mhz with the same CAS latency. This ram pairs really well with a core i7 2720, and the intel hd graphics seems to run a bit better too as expected (although that's not as big of a factor as my laptop switches over to my radeon 6770m when gaming). Not that it's really that important but it also increased my WEI memory score to a 7.8, and if your laptop runs entirely off of the intel integrated graphics that score would increase as well.

Cons: The only problem I could see is if it dies anytime soon. If it does I'll certainly update my review, but I haven't had problems so far.

Overall Review: Why don't all laptops with at least an i7 2720 ship with ram like this? Seriously it's fast, low voltage, and it's under $50. Which is why I refused to pay an extra $150 to go from 6gb of ram to 8gb when ordering my laptop. I mean for me it was incredibly easy to install my new ram, I didn't even have to remove any screws (I have a custom hp dv6t quad edition laptop because my dad works at hp and I needed a laptop for college).

Pros: Fast speed 8-8-8-20

Cons: Dunno

Overall Review: Purchased this for my new Toshiba P755 with an I7 Intel processor. Computer only came with 4gb, took that out and replace with two of these adata stick for my max 8gb ram. Shows my computer now running at 8-8-8-20. I was surprised because that exceeded my expectations. Only problem is I thought it would run at 1600 mhz and it shows it is only running at 665? I'm not sure how to get it to run at 1600? Went in what I thought was the Bios and don't see a way to change settings?

Pros: + Price + Low Latency (one of the best for laptops) + Low Voltage + A-DATA Quality (made in Taiwan) + memtest was flawless

Cons: -N/A

Overall Review: Replaced 4GB on my Sony Vaio E14 Windows Experience Index went from 5.9 to 7.5 To most commentators on here saying their battery life hasn't changed -it's important to realize that if you're upgrading from one module (~4GB or less), you're replacing your single RAM stick with TWO modules instead now. Despite the lower operating voltage of the XPG (vs. 1.5-1.65 typically), you're still powering TWO modules now instead of just one, so if anything, your battery life should either stay the same or possibly decrease slightly. My laptop didn't experience any significant change in battery life.

Pros: Does what it should & then some. Runs @ 1600 without an issue. My budget Samsung (NP365E5C-S05US) laptop AMD A6 w/ 7520G GPU are much faster now, considering the integrated GPU shares the onboard memory.

Cons: None @ all really. I guess it's been a tad cheaper price wise in the past.

Overall Review: Grab it! It appears that many people really like this RAM (as I do) & it's quick. If you have a budget laptop & want to bump it from 4GB to 8GB, then this is a real short money investment.
