MEMORY DEFECTIVE, NEVER WORKED, Purchased in 2013.. Will they honor their Lifetime Return and Replacement?

I purchased this item on May 4, 2013 to use on my DELL XPS 17 L702X Laptop (2 slots), which currently has 4gb x 2 of Sodium Memory which was installed by Dell when I purchased my Laptop on eb 21, 2012. I use this Laptop daily for years, and it is a wonderful device, but after upgrading from Windows 7, to Windows 8.1 (and now considering a Windows 10 upgrade), I need more memory to perform extensive daily multi-tasking.
After purchasing this memory I tried to install on the above Dell. I had no problems using the Dell, in fact the device would start up and look as though it was working fine, but within minutes the device froze. Since the device booted fine, I thought it might be a driver issue. I did extensive online research, but never found a working solution. About 2 months of trial and error, I removed the Komputerbay 16GB (2x 8GB) memory and replaced it with the original memory. Once the original memory was back in the Dell Laptop, the XPS L702X worked fine, but I still needed more memory.
I placed the memory in a storage box, and forgot about it. Then in eary 2015 I found a local computer repair store in Kansas City and took my Dell XPS L702X Laptop with my Komputerbay 16GB (2x 8GB) memory to this store to see if they could install the memory, add the proper drivers and get my laptop to work. Needless to say, the computer repair shop called me and told me that the Komputerbay memory was not good. (I had them re-install the original memory and brought my Dell XPS L702X home.)
I am online today and was looking for new memory for this same DELL XPS L702X, which I still use daily. I looked up my original memory order from Komputerbay and realized I have a life-time warranty. WONDERFUL!
I am writing this review with the FULL intention of tracking my return and replacement process. Today is October 3rd, 2015, and the first probelm I've had is locating the email address to contact Koputerbay (the return process should be easy and seamless), but I have searched their profile and other places, and have not yet found their email address. I've also tried contacting them via Amazon, and I will let you know how quickly I can find their information and exactly how well the process goes.
If they respond quick and replace the memory, I will update this review and hopefully they will delight ME, the customer, and I will be able to write a wonderful 5 star review of my experience, including if any help they might provide to assist in troubleshooting. Have a great day!

Upgraded my iMac 27-inc, Mid 2011, from 4 GB to 20 GB of total RAM.

I've added this pair of memory modules to my iMac 27-inc, Mid 2011, to upgrade from 4 GB to 20 GB of total RAM.
Despite the Apple documentation claiming that 16 is the maximum capacity for this model, I researched and found that you can max out to up to 32 GB.
For those people that have no clue (like me), the installation was really easy:
1 - Turn off your iMac. Touch the iMac frame to discharge you (electrostatic), and unplug it from A.C. Place your iMac "face down" in a towel.
2 - unscrew the 3 bolts from the memory bay at the bottom of the iMac, remove the memory cover.
3 - leave the 2 RAM modules in their slots (I had 2 RAM modules, of 2 GB each).
4 - Insert the NEW 2 RAM modules (8 GB each) in the 2 available slots.
5 - Screw the 3 memory cover bolts, get it up back in place and turn it on. That's it.
By looking at the "About this Mac > Memory" screen, I went from:
[ 2 GB ] [ 2 GB ]
[ ] [ ]
To:
[ 2 GB ] [ 2 GB ]
[ 8 GB ] [ 8 GB ]
Hope this helps!

Great upgrade for Lenovo Y410P, HP Chromebox. CT2K8G3S160BM/CT2C8G3S160BM and CT2KIT102464BF160B/CT2CP102464BF160B are identical

I purchased the Crucial CT2K8G3S160BM 2x8GB to increase the memory in my Lenovo Y410P laptop from 8-GB to 16-GB. My Y410P has two memory slots, and one slot was already occupied by a factory-installed Samsung M471B1G73QH0-YK0 8-GB memory card. I probably could have just added another 8-GB card. But to avoid any possible memory glitches, I prefer not to mix-and-match memory cards of different types. The existing Samsung memory was PC3L/DDR3L, with the 'L' signifying that it is low-voltage 1.35V memory, whereas the standard PC3/DDR3 memory uses a higher voltage of 1.50V. You should not combine memory of different voltages or use memory with incorrect voltage since your laptop may not even boot up. To further maximize compatibility with my laptop, since it came equipped with CL11 1600-MHz memory, I likewise wanted to stick with CL11 CAS Latency speed, instead of going for memory with a faster (lower) CL rating. Some CL9 memory cards have faster specifications, but I really think that most people will not notice 2-nanoseconds of extra latency. So I ordered this CL11 1600-MHz memory because I wanted to exactly match the specifications of my laptop's original 8-GB memory card to ensure compatibility since using mismatched memory can cause system instability. And this memory has been working flawlessly in my laptop!
In real-world applications benchmarks, there is barely any difference between using CL11 memory and using some fancier CL9 memory, and the unnoticeable speed difference is not worth paying extra money for more-expensive models of CL9 or faster memory. With most applications, if you compare CL7, CL9, and CL11 application benchmarks, the differences mostly amount to 2% to 4% differences in benchmark timings. Along with the CL listing, another important memory performance indicator is bandwidth, and this Crucial memory's DDR3 1600MHz has a very good maximum bandwidth of 12800MB/s. But what does this mean in real-world performance terms? Relatively little. As long as you have enough memory to hold the applications that you are running without paging, RAM speed is only very rarely a performance bottleneck. Even with quad-core CPUs, the bottleneck is more likely still going to be the CPU . The reason for this is that the CPU's branch prediction algorithms are so accurate that, in the vast majority of circumstances, the data is already in the cache when the CPU needs it. So direct calls to RAM are quite rare. The branch predictor is like the CPU's personal assistant; it guesses what piece of information the boss needs next and makes sure it is already on his desk by the time he needs it. Occasionally, the assistant will get it wrong and the boss will have to forage around and find the information himself. In CPU terms, "foraging around" means retrieving the information from RAM, or (worst case scenario) disk, while if it is "on the boss' desk", that is equivalent to it being in the CPU's cache. And if your computer is equipped with an SSD using Intel's "Smart Response Technology" or if your computer uses SSDs instead of hard disks, it may retrieve the data from the speedy SSD instead of reading from a slower hard disk.
So the days are long-gone when purchasing high-end expensive RAM actually makes a tangible difference to your computer's performance. As long as it meets the basic specifications that your chipset requires, there is not much to be gained by paying more. Some performance gains are possible from buying better RAM, but these days, most tests tend to show that such performance gains are minimal... far, far lower than you will get from adding more RAM (not necessarily faster RAM, just *more* RAM) or a faster CPU. This was not always the case. When the Pentium IV first came out thirteen years ago, it used a new type of RAM that had, at the time, very high bandwidth, but also very high latency. AMD's Athlon used traditional RAM with lower bandwidth and lower latency. Some types of applications (e.g. video and audio conversion) were very sensitive to bandwidth, but less sensitive to latency. These types of applications showed significant performance gains with the Pentium IV. Other applications (typically games and office applications) were more sensitive to latency and favored the Athlon.
Overall, this Crucial memory is a great buy! Don't overspend on memory just because a brand or model of memory touts better specifications. If you are a hardcore computer gamer with a $4000 gaming laptop, you may opt for faster high-end memory to complement your top-of-the-line CPU and graphics. But most people should focus far more on how compatible that memory's specifications are for your system because the differences between CL ratings are negligible if you are considering CL rating differences of 2 or 3, while using memory that is not correctly matched or compatible with your computer can cause a variety of problems.
After I removed the original Samsung 8-GB memory from my Y410P laptop and added these two Crucial SODIMM cards, I reran the Windows Experience Index benchmark and got the same WEI "Memory operations per second" score of 8.1 that I had with the Samsung memory. The WEI "Processor: Calculations per second" also remained unchanged at 8.1. This was not surprising considering that both the original Samsung memory and this Crucial memory have the same specifications.
I also purchased a single 8GB card of this same Crucial memory to upgrade my HP Chromebox, which comes equipped with only 2GB in its single memory slot. There is a lot of misleading information on the Internet stating the maximum memory that you can use in the HP Chromebox is 4GB. But that is incorrect since the HP Chromebox can fully use 8GB of memory. After I upgraded my HP Chromebox, the Memory Monitor app on its Chrome OS displayed the memory capacity as 7.9GB. 2GB of memory is sufficient for a Chromebook/Chromebox if you are just browsing with a few tabs open. But if you want to open up lots of tabs and run lots of apps, or if you plan to install Linux or Windows on your Chromebook/Chromebox, then adding more memory will help with performance.
Note that Crucial has two identical 16-GB 2x8GB kits with identical specifications, with each memory product having two different part numbers: CT2K8G3S160BM/CT2C8G3S160BM [[ASIN:B008LTBJFW Crucial 16GB Kit (8GBx2) DDR3 1600 MHz (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Mac Memory CT2K8G3S160BM]] , and CT2KIT102464BF160B/CT2CP102464BF160B [[ASIN:B007B5S52C Crucial 16GB Kit (8GBx2) DDR3 1600 MT/s (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Notebook Memory CT2KIT102464BF160B]]. CT2K8G3S160BM/CT2C8G3S160BM and CT2KIT102464BF160B/CT2CP102464BF160B are exactly the same memory cards, with the only difference being that the CT2K8G3S160BM/CT2C8G3S160BM product is packaged for Macs with the words "Mac Compatible" on the package. But all four of these part numbers are totally interchangeable because they contain identical memory cards. So if you determine that this is the right memory for your computer, just get whichever of these four Crucial part numbers is cheapest :-) I purchased the CT2K8G3S160BM/CT2C8G3S160BM on Amazon because it was $30 cheaper than the CT2KIT102464BF160B/CT2CP102464BF160B product listing at the time (of course, prices can vary each day). Both of these products are dual-voltage and can work in either 1.35V PC3L/DDR3L or 1.50V PC3/DDR3 memory slots. Both products are Mac-compatible, but they are also not Mac-specific or PC-specific, and they work equally well with PCs, Macs, and Chromebook/Chromebox.

Didn't work for my 2010 21.5" iMac, but description says it should.

The description says that my 2010 21.5" iMac is compatible, but it was not. Tried this ram numerous times, in every combination I could, and my Mac would crash and restart every time. My Mac only returned back to normal once I went back to the original RAM it came with. All the specs seem to match Apple's specifications, except for volts. The RAM that came with my Mac says it's 1.35v, and using Crucial's online system checker, it recommends RAM that is 1.35v too. Which is strange because OWC tells me 1.5v, and most of the research says that 1.5v should work fine. Unfortunately this RAM didn't work for me. I returned it and ordered RAM made by Crucial that is 1.35v.

Better Than Expected: Inexpensive and Entirely Satisfactory

I replaced the OEM RAM in my ASUS U32U-ES21 notebook PC (originally specced with 4 GB RAM) with Corsair's 8 GB ValueSelect RAM kit.
Sure, I could have bought a single 4 GB SO-DIMM, but it wouldn't have saved me all that much money, and when possible I like to run matching memory modules in my machines.
I also could have paid one and a half times as much for a different set touting itself as specifically-designed for ASUS' U-series and their ilk, but considering that I paid less than five hundred bucks for the U32U when it was new, Corsair's comfortably-priced ValueSelect option seemed worth a try.
Corsair's packaging was clearly labeled and easy to open. I don't usually comment on packaging in product reviews, but it seems relevant here: the manufacturer's packaging for this upgrade kit is designed so you don't have to wave sharp objects around to extract your new memory modules, nor do you have to worry about getting label adhesive on your fingers and transferring it onto the precious cargo within.
A little round sticker at the top of the box kept it closed; I just ripped that whole part of the box off and went to town. Inside, the memory modules were packaged in a little two-piece plastic shell that came apart easily with finger pressure while still keeping the modules contained until I was ready for them.
The modules themselves are pretty much your standard DDR3 SO-DIMMs: green circuitboard, gold pins, bunch of black chips. They feel nice and rigid, with just enough flex to help get them in and out of their seats. They're definitely pretty durable (they certainly withstood the abuse they took during installation).
I don't particularly love the giant sticker that covers the whole front side of each module, but it doesn't appear to impact performance in any way, so I'm not knocking off a star for that. Maybe if I could knock off a quarter of a star, I would, but that's mostly a matter of taste. For all I know, it might actually serve some purpose (maybe it's glued on with cooling paste, or something?).
Installation was a pain in the neck, but that's not Corsair's fault -- it's a function of the way the clamps that hold the modules are arranged in my particular machine. Your installation experience will vary based on the design of your particular computer. If one or more of the modules is seated incorrectly, of course, the machine won't boot, leaving you to pop the cover back off and fiddle with it some more. Once the modules were properly seated (after much grumbling, dramatic sighing, and gnashing of teeth), my previously-wheezy old notebook booted right up.
I expected a performance boost, but was actually really surprised by exactly how significant a boost I got.
The U32U-ES21 was never intended to be a high-powered machine, but it's much, much quicker and more fun to use now. MS Office applications pop right up; Chrome runs like ... well, if not a cheetah, at very least a pretty fast pony; even a concurrent session of Photoshop, Pidgin, and a handful of Chrome windows flows along swimmingly.
I guess I'll have to find a new window in my day for making a cup of tea; I no longer even remotely have time to do it while Photoshop launches. Meanwhile, Sims 2 and Sims 3 are significantly less slow, if not exactly blazing fast.
In short, and perhaps rather obviously, dropping in 8 gigs of shiny new RAM won't turn your lazy old work mule of an notebook into a blazing gaming hoss. It can make you feel like you've got a whole new, much-peppier mule, at any rate -- and, in my case, I got a much peppier new mule than I was expecting, which is really quite nice.
For about fifty bucks (at the time of purchase) with fast Prime shipping, I'm very happy with it.
Full disclosure: one of my first "real" jobs was working in ASUS' tech support center; Corsair was one of the brands of RAM we routinely recommended for its reliability based on our experiences kludging together various motherboards and so forth that we got to build up in-house so we'd know what our callers were facing. That certainly influenced my purchasing decision. However, I have long since wandered away from the hardware-support world (though I do still do some tech-oriented work), and I paid Amazon's full price for this upgrade kit.

Great RAM

Size: 16GB KIT (8GBx2)
Verified Purchase
I bought this upgrade for my 2009 iMac 27" i7. I already had 4 x 2GB sticks in my iMac, but needed more speed for Photoshop and Final Cut Pro. I installed 2 x 16GB along side 2 x 2GB sock memory (YES YOU CAN DO THAT!) to give me a total of 20GB. I had no compatibility issues and it produced a very noticeable speed boost. If you feel your Mac is in need of more memory, I would recommend the following to know if your RAM is the issue: Open Utilities folder -> Open "Activity Monitor" -> Click the tab at the bottom labeled "System Memory" -> Just below that, you should see a few sets of data...The important ones are:
"Free" : If your "Free" memory is low (or 0!) you probably need more memory.
"Page Outs" : If the "Page Outs" is high, this means that your computer is using hard disk rather than RAM for memory functions and produces a severe loss in speed.
"Swap Used" : This gives a rough estimate of how much hard disk is used for RAM. This will give you a rough idea of how much RAM you should add. i.e. if this is 4 GB, then you should add at least 4 GB.
You should check these numbers while doing the types of activities you normally use your computer for. Not just at idle with nothing running!
As far as this item goes, Crucial is a known Apple-friendly RAM and is unlikely to give you any issues. It is also a high quality manufacturer and is much more reliable than some cheaper brands. Remember, RAM is dirt cheap these days so don't save a few $$ to buy inferior quality RAM! You should just not buy any if you are going to buy a terrible brand.
iMac install is really easy! You can find many manuals on the internet (I prefer iFixit). Don't be intimidated buy installing it. You can save a lot of money by doing it yourself. If you feel uncomfortable, then by all means have someone qualified to do it for you.
