Corsair 1024MB PC3200 DDR Memory
The Corsair CMX1024-3200C2 is a 1024 MByte DDR SDRAM DIMM designed for extreme speed and is one of the fastest 1 GByte modules available. This part delivers outstanding performance at high clock speeds. It has been tested extensively in a variety of motherboards commonly used in gaming rigs. This memory has been verified to operate at 200 MHz (DDR400) at aggressive latencies of 2-3-3-6.

| Computer expert here. This ram is the best money can buy for pc3200 400. This ram is very fast realiable and overclocks extremely well! Abit sli k8n socket 939 Amd athlon 64 4000+ 2.4ghz overclocking a bit at a time cuz ive only had this for a few days now but at 2.532ghz western digital sata 3.0gb/s 16mb cache 320gb. ati radeon x1300pro pci expressx16 dual dvd burners xion gaming case 450wattpower supply and 1 gig of this ram plan on getting another stick soon i dont no why because this computer is super fast no need for dual core..my benchmarks are off da chains |

What You Should Know
|
Before you buy - make sure your motherboard is compatible with this memory. For example, DDR Memory won't work with motherboards designed for only DDR2, SDRAM or RDRAM memory, and vice versa. Only use the memory speed recommended by your motherboard's manufacturer. Please read the specifications carefully or call us for expert advice.

Inside Memory: It's All About The
Numbers
by John H., The Component GuruWhat's The
Secret To Memory Specs?
What do all those memory numbers mean?
Memory speeds, timings, and bandwidth play a critical role in the
performance of your computer. Unfortunately, many people don’t actually understand what each number
represents and what each actually means to them.
DDR Is Not A Video Game!
The most commonly seen memory specifications are those for SPEED! Numbers similar to PC3200
and DDR-333. While these values represent different specs, they are linked together. For instance, a
memory module may be specified as DDR-400 and PC3200 or DDR-333 and PC2700. The “DDR” number refers
to the actually frequency of the module (400MHz in the first case), while the “PC” number refers to
the transfer rate (3200 MB/s for the same module). You may notice a pattern here. The “PC” is always
going to be roughly 8 times the “DDR” number (it's rounded off). So the next time you
see a DDR value, you can actually calculate the PC value from it or at least know the specification
is correct.
The PC5400/ PC5300 Controversy
The 8x DDR formula holds true for most of the newer types of DDR memory also. For example, DDR2
modules may show you a speed of DDR-800, which gives a transfer rate of PC6400 (8 X 800). However,
one type of memory often causes confusion. That memory is DDR-667. Why this one in particular? This
module has an actual transfer rate of 5336 MB/s. (667 x 8 = 5336), which seems to be a difficult
number to represent. In most cases, the transfer total is simply rounded off. The problem with
DDR-667 is that the various manufacturers making these memory modules don't agree on a common,
rounded-off figure. Some call it the more accurate PC5300, while others went with the
faster-sounding PC5400, thereby confusing nearly EVERYONE without a Ph.D. in computer engineering.
People owning computers using this type of memory run into problems when they try to upgrade their
memory and can only find one or the other. They open their computer, or use a memory configurator to
find out what type of memory they need, and see PC5300. When they attempt to order the memory, all
they find is PC5400, not realizing it’s the same thing as PC5300. So remember, when it comes
to PC5300 it's exactly the same as PC5400!
Memory Timings (Latency)
The other scary set of memory numbers you’ll often encounter are the memory timings, or latency.
This is shown by four numbers, separated by hyphens (x-x-x-x). Each measures the time (in clock
cycles, just in case you were wondering) the memory takes to perform certain actions (keep this in
mind for later). I’m not going to explain specifically what each number means (for those of you that
actually have the computer engineering degrees, you already know this. As for the rest of you – this
is esoteric info that only folks who have advanced computer degrees need to know). All you really
need to know is this -- a lower number is generally faster. The number most often mentioned in the
specs is the first digit, known as the CAS latency. In DDR memory, values of 2-3 are common, while
in DDR2 it is usually around 5, and can be as high at 10 for DDR3.
Lets Be Clear - Smaller Is Better!
Okay, it’s likely that I’ve thoroughly confused you by telling you that a lower number is faster,
rather than what you thought was the fastest, and actually has the slowest timings. Let me
clear this up! Going back to my explanation that the numbers measure the number of clock cycles it
takes the memory to perform its tasks: Because the clock speeds of DDR3 are so much higher than DDR
or even DDR2, it can complete each individual clock cycle A LOT faster. In other words, while it may
take 9 cycles to do a task, that’s still a lot quicker than the 2 or 3 cycles it took the DDR memory
to do the same task. Keep that in mind as you shop for memory. The timings only make a good
comparison between modules if you are looking at two of the same types, i.e. two DDR3 modules, but
are meaningless when comparing DDR to DDR2 or DDR3. |

How Much
Memory Do You Really Have?
When you look at the specifications for a computer, it will display the
installed memory, and typically the maximum memory that can be installed.
However, while these are real values, they represent a potential useable
memory depending upon the installed operating system, and other factors. The actual useable memory may be different
(lower) from these values.
The reason is simply that a computer may have a limitation in the operating
system (such as Windows 32 bit versions), or configured to use shared memory,
which reduces the amount of RAM that is available to the CPU by using
some of it for other purposes, such as for video memory. In some
cases, you can control the maximum useable memory through system settings,
by upgrading from a 32 bit to a 64 bit version of Windows XP or Vista, or by upgrading to a video card that has internal onboard video memory.
But always
remember, that the amount of memory that your system reports, is not always
the amount of actual installed memory. For example, if you have 4GB
installed, 32 bit versions of Windows will typically report 3.2GB due to a
limitation of Windows itself. Also note that different Windows
programs report available and maximum memory differently, which can be
confusing. If you find that you need more
memory, we suggest expanding your system memory, since this is the most
effective performance increase, and the one that is easiest to perform .
