Can you use ddr3 memory with ddr2 chipset?
Unfortunately, no. DDR RAM will not work in a DDR2 motherboard, and DDR2 RAM will not work on a DDR3 motherboard.
There are a few motherboards that have slots for both DDR and DDR2, so it is conceivable that there could be motherboards with slots for both DDR2 and DDR3.
Follow these steps.I hope this help.
Step 1: Identify your current BIOS version.
The easiest way to find your BIOS version is to open up the System Information app in Windows--just type msinfo32 into the search bar (for Windows 7/Vista) or the Run box (XP), and click System Summary; your BIOS version should now show up on the right under your processor speed. Record your version number (and the date that appears afterwards, if applicable).
Step 2: Check your PC/motherboard manufacturer's Website for BIOS updates.
Most PC manufacturers handle BIOS updates based on your specific line and model, so head over to your manufacturer's support page and check its listings for your PC, because if you download and install a BIOS intended for a different model, your PC probably won't work (although most BIOS updaters are smart enough to notice if you try to install them on the wrong hardware). If there is a BIOS update file available, grab it--along with any documentation it comes with, because often warnings and specific instructions are contained in the Read Me docs.
Those of you who assembled your PC yourself will need to look for BIOS updates from your motherboard manufacturer's Website. If you don't remember your motherboard's model number, you can look it up without opening up the case by downloading and running CPU-Z and clicking on the Mainboard tab.
Step 3: Read the included documentation.
The BIOS updater's Read Me file will most likely include a list of fixes and new functions, often to support new hardware. Updating the BIOS for my Lenovo Thinkpad T500, for example, added support for a new AC adapter and a 1600-by-900-pixel screen resolution on an external monitor; the update also fixed fan speed and Webcam issues that could not have been handled by updating Windows or my specific device driver software.
More important, however, were these notes in the Read Me file: If I was running Vista on my T500, I'd need to make sure that I had a certain patch installed; and if my T500 had a certain graphics card, I would need to update its drivers above a certain version before updating my BIOS. Read and reread your docs, or you might make your PC unable to boot without even knowing why.
Step 4: Update your BIOS.
Most newer PCs have a fairly easy BIOS update procedure: Just download the .exe file from your PC manufacturer's Website, quit all open programs, run the .exe, and let it handle the patch; then reboot. If your PC suddenly shuts down in the middle of the BIOS update, you won't be able to boot up, so make sure you're not running off a laptop battery. Ideally, you're plugged into an uninterruptible power supply (UPS), especially if you're in an area prone to blackouts.
How much RAM can you install in a computer with an Intel Pentium III 450 MHz processor?
That will depend more on the motherboard and chipset used than the processor. Motherboards of that era would probably support between 256 and 768 MB of RAM, Most likely, the largest size modules you can use is 256 MB, so multiply that by the number of RAM slots and you'll have agood idea of how much your board supports.
It really depends on what type of data you are storing. If you are storing text documents then you have enough space to last along time. If you are storing pictures it depends on the size of the pictures saved, if your average picture size is 1MB then you could store about 122,880 pictures. If you are storing larger files like movies, which can range in size from 700MB to 4GB, on average you should be able to hold about 120 movies. Programs such as games can take up substantial room, from 1GB to 20GB, so you can fill up space fairly quickly. Of course if you have windows xp installed you will loose about 1.5GB, if you are running something different like vista, linux, or an older version of windows the amount of space taken up will vary. You rarley have access to all the space on your hard drive, some space is reserved for things like the MBR (master boot record) and other things.
This should give you a better idea of how much space 120 GB is,
1 Byte is equivilant to one charaacter, such as the letter "A"
1024 Bytes is equal to 1 kilobyte, or about half a page of text.
1,048,576 Bytes is equl to 1 megabyte, or about 1 small novel.
1,073,741,824 Bytes is equal to 1 gigabyte, about the size of a movie.
So with a 120 GB hard drive you have enough space for 128,849,018,880 Bytes, 125,829,120 kilobytes, or 122,880 megabytes.
To break it down even further 1 Byte is made up of 8 bits (which are actually just a sries of 1's and 0's) so you can store up to 1,030,792,151,040 bits!
Why is static RAM a lot more expensive than dynamic RAM?
SRAM does not need to be refreshed; basically it does have data remance although still volatile. Since it does not need to be refreshed it is better than dynamic ram, which needs to be refreshed periodically.
Mercury pi865d7 motherboard support which ddr RAM 1 or 2?
I have this motherboard with 1GB RAM but it is DDR.
If a Motherboard supports DDR it cant support DDR2.
How many bytes can be stored in a 300GB Hard Drive?
There are 1024 Megabytes (MB) in a GigaByte (GB), and then 1024 Kilobytes(KB) in a Megabyte, and then 1024 Bytes in a Kilobyte. So in a 300GB Hard Drive, there are 300 times 1024 times 1024 times 1024 Bytes, which equals 322122547200 Bytes.
In computer science, there is a memory leak, and all the available memory has been reserved, and part of the hard drive is used as virtual memory, and the computer is exchanging data between memory and disk as fast as it can. At this point cpu utilization is usually very low, as Hard disk read/write times are slowed down by the physical movement of a read/write head.
Caused by memory leaks or insufficient memory for an application.
Pettabyte exabyte yottabyte petabyte terabyte bit byte kilobyte megabyte gigabyte please order?
bit
byte
kilobyte (kB) = 1,024 bytes
megabyte (MB) = 1,024 kB
gigabyte (GB) = 1,024 MB
terabyte (TB) = 1,024 GB
petabyte (not pettabyte) (PB) = 1,024 TB
exabyte (EB or XB) = 1,024 PB
zettabyte (ZB) = 1,024 XB
yottabyte (YB) = 1,024 ZB
I find the mis-ordering of XB YB and ZB disconcerting, but I wasn't consulted when they were established a few years ago. If you were counting, a yottabyte is about 1.2E24 bytes. That is almost exactly twice Avogadro's Number (6.024E23), which is the number of atoms in one mole of a substance. A mole of carbon weighs 12 grams. The current world data store (Feb 2011) of data held electronically is about 0.8 ZB.

What device draws heat away from the CPU?
The central processing unit (CPU) of desktops and other performance computing hardware can be the source of high heat. Multiple devices are/and have been used to carry (or "cool") heat away from the CPU. These devices are commonly known as coolers. Specifically coolers can include a heat sink linked to radiator fins, heat pipes or liquid coolant lines. At the most exotic and experimental end of cooling includes using extremely low temperature liquid gas onto CPU to absorb heat.
ROM stands for Read Only Memory.
The ROM is non-volatile memory;it retains stored information even if the power is turned off (unlike RAM).This is basically used for storing programs and data that need not be altered one stored.
Processor uses ROM to store and execute programs instructions.However it is a type of prime memory and not a storage memory,therefore don't compare it with Hard Disks or CDs and DVDS etc
As the name itself suggests,the information can only be read not deleted,altered or even overwritten.This means that once a bit pattern is stored ,it is permanent or at least semi-permanent (if supports alteration).
The permanent groupincludes two types ,viz. ,ROM and PROM (Programmable ROM).
The semi-permanent also includes two types ,namely,EPROM (Erasable PROM)and EE-PROM (Electrically Erasable PROM). ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM ), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
If you ever do the hardware setup procedure with your computer, you effectively will be writing to ROM.
Most likely DDR3 SDRAM. It is capable of triple-channelling, hence the three yellow label slots. :)
List 5 types of memories of a computer?
Five types of computer memory are:
Dynamic Random Access Memory (DRAM)
Synchronous DRAM (SDRAM)
Static RAM (SRAM)
Double Data Rate RAM (DDR)
Rambus DRAM (RDRAM)
A website is how many kilobytes?
A website can have a huge range of sizes, depending on its content. It is not possible to say what size, without knowing what is in it.
they guy who writ this is a . t . w . a . t ., the answer is 240!!!
How many kilobyte is 2000 bytes?
1024 bytes the actual number of bytes in one kilobyte. 2048 is typically referred to as 2 Kilobytes but that is kind of a shorthand. So, technically 2000 bytes exactly would be 1.9531 Kilobytes in the computer world anyway. It all has to do with the binary number system where 2048 is represented with 16bits as 0000100000000000. Each bit from the right to the left is worth double the value of the right most bit that is worth a decimal value of 1. So, again from right to left the bit values are 1,2,4,8,16,32,64,128,256,512,1024,2048. For example the decimal value of 2047 would look like this in binary 00000111111111111. Just add the values of each bit from right to left and you'll get it.

What 3 considerations when chosing memory?
There are at least 5 considerations when it comes to choosing memory.
1. Type. The memory has to be compatible with your motherboard, be the correct family of memory, and come in the correct form factor. Even in the same families of memory, there are often multiple form factors. The ECC status is also important, and in some cases, the difference here might affect the number of pins.
2. Height. You do not want memory that is too tall to fit in the socket, if for instance, the socket is located under a huge CPU cooler.
3. Speed and latency. The faster the speed and the lower the latency, the better the performance.
4. Brand. Some brands have a better reputation than others and may be less likely to fail. In addition, some brands may be more compatible with your system than others.
5. Price. While paying more might get you faster or better quality memory, you might have an upper limit and may be willing to compromise the speed ratings a little to bring it into your budget.
How many bytes are in an exabyte?
1 exabyte (EB) = 1 quintillion bytes
quintillion = 1,000,000,000,000,000,000 = 10006 = 1018
An exabyte is 1000 petabytes, which is in turn equal to 1000 terabytes, which is equal to 1000 gigabytes, which is equal to 1000 megabytes.... and so on.
Is the secondary storage faster than main memory?
No. The secondary storage is typically slowerthan primary storage. But the secondary storage has higher capacity than primary storage.
