Review: Great quality. No complaints. - Exactly as described, works perfectly. No issues at all. I got this as part of an upgrade project for an old HP Pavilion that is on the verge of retirement. It's been my favorite device for creative writing and all around word processing for years (original manufacture date is 2016-ish) and I hate to let it go without a fight. There was some confusion and conflicting information as to whether this particular model could or could not be upgraded from 4gb to 8gb; so I took a chance... I'm glad I did. Works great. Very easy to pop-in as these old laptops had the access panel on back. There's a noticeable difference in performance. Great product. Very happy with it.
Review: easy Upgrade That Works Like a Charm - This Crucial 4GB DDR3/DDR3L RAM stick was an easy and affordable way to give my older computer a boost. Installation took just a couple minutes — popped it in, powered up, and it was recognized right away. The speed bump made a noticeable difference for everyday use like web browsing and light photo editing. It runs cool and stable with no issues or crashes. If you’ve got an older system that needs a little extra life, this memory upgrade does the trick without breaking the bank.

## Questions & Answers

**Q: What's the difference between DDR3L and DDR3?**
A: Standard DDR3 (JEDEC JESD79-3F) requires a supply voltage of 1.5V.  DDR3L (JEDEC JESD79-3-1A.01) requires a supply voltage of 1.35V.  In a nutshell, DDR3L is simply DDR3 that has been qualified to run under (slightly more stringent) DDR3L operating parameters with a 1.35-V supply voltage.  While running your memory at 1.35V instead of 1.5V does use less power and generate less heat, the memory device should be qualified to run that way--and should be labeled as DDR3L.  Standard DDR3 that has been verified to run at 1.5V *might* run at 1.35V... or it might not.  DDR3L, on the other hand, can nearly always be run at 1.5V--if the need arises.  My experience (through ~25 years of computer engineering) has been that the memory that doesn't make the premium binning selection (in this case, qualification for use as DDR3L), is usually relegated to the default binning (here, as standard DDR3).Sadly, the stock picture used in the item description shows a DIMM populated with 1 Gb (yes: gigabit, not gigabyte) chips, so it offers no insight into the operation of the instant item.  My recommendation is to continue to pummel Amazon with questions until they clarify the description as to whether or not this item is DDR3L qualified.

**Q: Trying to figure out if it is compatible with Dell XPS 2720.  Any way to confirm before purchase? thanks!**
A: The crucialmemory.com site isn't 100% accurate. It didn't suggest an 8GB module for my DDR3 (not DDR3L) Dell and yet the 8GB module works flawlessly.

**Q: I have a Macbook Pro 13 inch mid 2009 model with 2.26 GHz Intel Core 2 Duo processor. Will this work for my machine?**
A: I have a mid-2010 Macbook Pro 13in 2.4ghz and this did NOT work for me. After installation, I basically could not turn on my computer at all. I was worried, then I installed the old RAM that was in it originally and luckily it turned on. That being said, I had an older 2009 Dell PC Notebook laying around, I tried the RAM in that and that WORKED.  I would have liked to put this in my Apple Macbook Pro, but it just didn't work for me.  I did keep it since it's now in the Dell and did boost its performance quite a bit.

**Q: Is this actually 1.35V DDR3L, as opposed to DDR3 as stated in the name? The Gigabyte BRIX GB-BXi5-4200 I will use it in requires DDR3L.**
A: Some companies like Corsair use the designation 1.35v DDRL memory and others like Crucial do not use the designation L for 1.35v DDR3 memory.  The memory is "low voltage" in both cases, but one company uses the designation "L" and the other does.  The actual voltage of the memory is what is important and *all* 1.35v memory is low voltage.  This 1.35v DDR3 memory is the new standard for Intel Haswell chips.

### ⭐⭐⭐⭐⭐ Works Great with Alienware 2nd Gen i7 Laptop!
*by J***E on April 21, 2014*

This memory works great in my Alienware M17x-R2 laptop (Intel Core i7 Q740 1.73GHz, *8MB DDR3-1600, NVidia GeForce GTX 285M-1GB, 2 x Samsung 640GB SATA 7200RPM HDD-RAID1 configured, and WD Elements 1TB eSATA HDD). I usually try to give informative unbiased reviews unless the product is trivial, like cables and novelty items. Sometimes my reviews can be a little wordy, but I do it mainly to help novice to intermediate users. This particular review, became more of an Alienware review than it is about the memory. I any case, if you are an Alienware owner, you should know this memory will work for you. The improvements I've noticed by upgrading from 4GB (DDR3-1333) are small at this point, but significant since I'm no longer having crashes from insufficient RAM particularly when I switch between log-ins. I'm running a lot of peripherals and multiple Operating Systems; Windows 7 Pro SP1 64bit, Red Hat Fedora 20, and with MS Virtual PC 2007, I'm using XP Media Center Edition 2005 SP3 32bit, Vista for Business SP3 32bit, and 7 Home Premium SP1 64bit. I know this system is compatible, but I haven't installed Windows Pro 8.1 64bit yet and I'm still not sure if I want to. I use this system for both gaming and as reference with desktop support calls, which is why I use two versions of Windows 7 and probably should add 8.1. The boot time has improved moderately for each of my operating systems, in some cases only by a few seconds which I attribute to my multi-boot configuration. Load times for some software under Windows has also improved, as with Adobe Photoshop CS5, and The Sims 3. Virus and malware scanning time has been cut down by nearly half the time. Since this system memory bus can only support 10666MHz, I am not seeing any changes in benchmarks due to the 12800MHz capable RAM upgrade, nor did I expect to. The memory is perfectly stable at the slower rate. Windows Index Rating also remains the same, and because Linux has low overhead system requirements - it's still just plain fast. I would have bought the 16GB kit, but I was getting conflicting, false, or misleading information about the maximum limits from my owner's manual and Dell technical support. The manual says 8GB and I have 3 different answers from Dell's staff who stated a) ...your system was delivered with the components it was designed to support... it took several tries for me to understand the accent before I realized he was implying it cannot be upgraded at all, b) The system will support up to 16GB, providing you have updated the BIOS to version A12, however, that was erroneous because the last firmware release is A10, and c) Windows only supports up to 4GB of RAM... which is argumentatively true under a 32bit environment and XP, but I'm mainly running W7 64bit so the response was irrelevant. Other sources claim it WILL support 8GB and may or may not support up to 16GB. I was not willing to risk the expense and hassle of finding out first hand and went with 8GB based on my manual and the fact that it was the largest kit offered on the Dell website for the M17x-R2. I've used Crucial Memory in several computers over the past years and have always had excellent results. The reliability has been unsurpassed by other makers. Its stability has given me and my clients months of run-time without failure in servers, desktops, laptops, and even printing devices. I hope this helps.
