The maximum amount of memory that your system can use is actually limited in two ways — not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept. For instance, when you install 4GB of memory in a 32-bit Windows operating system (the most common version; 64-bit systems are typically used only by high-end users), your system will see (and utilize) only 3GB or 3.5GB. Is the problem bad memory? Relax, there isn't a problem with the memory. Windows allows for 4GB of memory to be addressed, but this isn't 100 percent the same as having 4GB of physical memory.What happens is that some of the addressable memory (regardless of how much you have physically installed) is reserved for use by page files or by some of the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc., so it's unavailable for use as normal main memory. The amount of memory needed for these devices is calculated by your system at startup; if you haven't maxed out the memory in your system, it's invisible to you, and all your physical memory (the RAM that's installed) is available for use. However if you've maxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM. The maximum memory limitation varies by operating system; for instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.Memory maximums for current Microsoft® Windows OSs include:
Windows 8 (32 bit)
Windows 7 (32 bit)
Windows Vista (32 bit)
Windows XP (32 bit)
Windows Server 2003 (32 bit)
* Certain Microsoft server operating systems can support over 4GB of memory via Physical Address Extension (PAE). Please refer to Microsoft knowledgebase article located here for more information.
Windows Server 2008 (32 bit)
Windows 8 (64 bit)
Windows 7 (64 bit)
Windows Vista (64 bit)
Windows XP (64 bit)
Windows Server 2008 (64 bit)
Windows Server 2012 (64 bit)
You already know that high-bandwidth applications and programs are memory intensive – stuff like photo editing, streaming music and video sites, games, or high-end productivity software. But what about just surfing the Internet?
The Memory Experts at Crucial were determined to find out.
We have our browsers open all day – checking news sites, social networking, doing research. Our browsers work hard, but how much memory does browsing require? The folks in the Crucial Performance Lab took it to the test, and here’s what they learned.
To test the memory usage on browsers, we picked 20 of our favorite Web sites*.
Our initial screen shot (captured with no browser opened) showed memory usage at 18 percent.
First, we opened Internet Explorer 9 and opened 20 blank tabs, populating each with our chosen web sites. Our usage shot up to 43 percent.
Next, we tried Firefox 4. Importing again our 20 web sites, the usage went up to 56 percent.
Finally, we brought up Chrome 4, opened our 20 web sites, and the memory usage rocketed to a whopping 65 percent!
We don’t often associate memory use with web surfing, but the bottom line is this: the more tabs and browsers you open, the more memory you use. If you find yourself frustrated with slow page downloads and response time, try a memory upgrade from Crucial.com.
We’ve got compatible memory for nearly every system out there…old or new, PC or Mac, notebook or desktop. Start here.

We have lots of videos for you to watch on our YouTube Channel. And if you’re ready to take the plunge, use the Crucial Memory Advisor or the Crucial System Scanner.
What is my computer model?
Make and model. It's easy if you're talking about your car — not so easy when you are talking about your computer. Sure, you know if you've got a desktop or laptop. And you know the manufacturer. But beyond that, model specifics can get confusing. When finding a compatible memory upgrade, knowing your exact model is important — here is how to figure it out.
Are you upgrading the computer you are working on right now?That's easy. Use the Crucial System Scanner. This downloadable tool determines the memory in your computer and tells you what your computer needs. Don't worry — no spyware or anything like that. The tool just looks at the technical, boring details of your system motherboard.
How does it work? Watch this video.
Are you upgrading a different computer?You can use the Crucial Memory Advisor. In just three clicks, we can tell you what memory upgrades are available for your system. But, you will need to know the make and exact model.
If you're using a Windows-based system, the model will be specified on the label, a small sticker on the back or
side of your desktop system, or the bottom of your laptop.
If you can't find the label, you can find model information this way.
Start ==> My Computer ==> Right click ==> Properties.
Or for more detailed info go here:
Start ==> Run ==> Dxdiag
You'll see "System Model" — that is the specific model of your computer and the information you'll need to use the Crucial Memory Advisor.
On a Mac system, you can find your system by first going to the Apple icon on the top left.
About this Mac ==> More info
Once you've determined the model, use the dropdown menu on the Crucial Memory Advisor to determine compatible upgrades.
Voltage refers to the power consumed by a module. In the past, most DDR3 memory voltage ranged from1.5 - 1.65v. More recently, dual 1.35/1.5 voltage modules came available at Crucial.com. While the lower voltage memory has some advantages over high voltage (namely lower power consumption), your system must support it in order to realize the benefits.
If your original installed memory is 1.5V and you are adding a dual-voltage 1.35V/1.5V module to an open DIMM slot, the dual-voltage module will operate at 1.5V, not 1.35V. In order to run at 1.35V, all installed memory modules must be dual-voltage 1.35V/1.5V and the system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V.
Generally, lower voltage is optimal as it consumes less power and in turn, may generate less heat. However, it is important to note that the overall system must support DDR3L (1.35V low voltage) to enable the module to run at 1.35V. If the system does not support DDR3L (1.35V low voltage), the module will run at 1.5V.
Purchase whichever of memory your system supports, but keep in mind the dual-voltage module will run only run at 1.35V if your specific system supports that voltage, otherwise the memory will run at 1.5V.
You can find and choose the best right memory upgrade options for your computer through the Crucial System Scanner or Crucial Memory Advisor. It's that easy.
How do I know what kind of memory to purchase?
Crucial makes finding the right upgrade easy. We offer two ways to find the right memory — our System Scanner tool and our Memory Advisor™ tool.
Our System Scanner tool automatically scans your system to tell you about your current memory configuration and recommend compatible upgrades for your specific system.
Or, use our award-winning Memory Advisor tool, where we've compiled all the information you need into one easy-to-use, searchable database. Our Memory Advisor is the most complete tool of its kind, with more than 250,000 solutions for over 50,000 different computers, printers, servers, and more. All you have to do is tell us what system you have, and our Memory Advisor tells you what upgrades will work for you. And we guarantee the memory you buy through the Memory Advisor will be 100 percent compatible with your system, or we'll refund the price of the incompatible module.
I Have a Dell Precision T5500 that currently has 2 x CT51272BA1339 4GB and was hoping to add 2 x CT51272BD1339 4GB. To me the spec looks the same between them but the later doesn’t come up in compatible list for my computer on the Crucial website, should these work?
Sorry probably would have helped if I gave the specs
Current Memory - CT51272BA1339
4 GB 240-pin DIMM DDR3 PC3-10600/ Dual Ranked / CL9 / Unbuffered / ECC / DDR3-1333 / 1.5V / 512Meg x 72
Possible New Memory - CT51272BD1339
4 GB 240-pin DIMM DDR3 PC3-10600 / Dual Ranked / CL9 / Unbuffered / ECC / DDR3-1333 / 1.35V / 512Meg x 72
Does any one know if the standard (i.e.. unbuffered, non ECC) 4GB 1333MHz UDIMM modules or kits come with a thermal sensor included (the SPD one) ? Last year, I bought a 4GB standard SODIMM DDR3 from crucial and was surprised to see that this module was equipped with this very useful thermal sensor. So I would like to do the same with my desktop computer now. This kind of sensors can be correctly detected by any modern hardware utility (i.e.. Hwinfo or Aida64,...).
I got 4 CT25664AA1067-16FHZ sticks for my MSI Platinum P35 motherboard to replace the 4 GB I had and up it to 8 GB. I had all 4 DIMMs filled before and they all worked fine. Now when I put in all 4 of the new RAM, it always crashes. If I only put in 2 sticks so I have 4 GB of RAM, no problems. Doesn't matter which 2 DIMM pairs I use or which 2 pairs of RAM.
Any suggestions? I've checked the bios and I've taken the memory out and reseated multiple times. I'm at a loss and seems like I should just return both pairs since I can only get 4GB to work and I had 4 GB originally.
Thanks in advance.
We have an IBM x3755 M3 - 7164D2G system with 4 x AMD 6272 CPUs
We want to install 16x16GB memory modules and to add another 16x16GB memory modules in the future, for a total of 32x16GB=512GB.
Here http://www-03.ibm.com/systems/xbc/cog/x3755m3_7164/x3755m3_7164mem.html the only 16GB memory module listed is: (1x16GB, 4Rx4, 1.35V) PC3L-8500 CL7 ECC DDR3 1066MHz LP RDIMM
In the Crucial products I haven't found any 16GB quad-rank x4.
Will the CT16G3ERSLD4160B - http://www.crucial.com/eu/store/partspecs.aspx?IMODULE=CT16G3ERSLD4160B modules work OK? (DDR3 PC3-12800 • CL=11 • Dual Ranked • x4 based • Registered • ECC • DDR3-1600 • 1.35V • 2048Meg x 72)? Will there be any performance difference?
I upgraded Dell 1545 Memory with Crucial 8 GB Kit(4 GBx2) DDR2 800 MHz (PC2-6400) CL6 SODIMM 200-PIN, purchased from eBay and following is the result. I am curious to know whether this is expected, with such high latency rate ?
When I ran Crucial Memory Scan it shows: [http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=3E9CBA9731D926C3]
Memory Type: DDR2 PC2-6400, DDR2 PC2-5300, DDR2 (non-ECC)Maximum Memory: 8GB Currently Installed Memory: 8GBTotal Memory Slots: 2Available Memory Slots: 0
Could you plese tell, is there any mismatch in frequencies between RAM modules supplied to me, in which case I'll return or is this in expectation - do appreciate very much ?
