Hi ive read alot about how video card memory, is double its clock?

Like my DDR2 On my 7600 is actually 800mhz? when it says it has 400mhz RAMDAC?

I look at this 8600gt and it had 700mhz memory clock, but was running at 1400mhz?

Whats this all mean, anyone clarify thanks.


Also, is this a good first build? *IGNORE THE HARD DRIVE*

ddr2 like times 2 double it.
duo core example 1 core is lets say 1.5 ghz so duo core is?3.0 ghz.



Intel® Core™2 Duo Processor Overview


Kingston HyperX KHX9600D2K2/2G DDR2 2GB Memory Kit - TrustedReviews

The processing speed of the main chip, the CPU.CPU speed is measured in Mhz, (megahertz).

A 2MHz CPU is faster than, but NOT twice as fast as, a 1Mhz CPU. < This is a CPU.
It plugs into the motherboard and has a cooling fan fitted.How much memory is available. The amount of memory required to run programs has steadily increased.
Today, minimum memory requirements are c 1 to 2 Gb, (Gigabytes).
Older computers will not have this much.
Programs will therefore run slower than they would on more modern computers.< This is memory.
Memory modules are pushed into slots in the motherboard.The state of the hard drive or disk. As with memory, hard disk sizes have increased with time.
When Windows need for memory exceeds that which is available, it tends to temporarily store data on the hard drive.
Here, a large hard drive helps.

There appears to be some confusion, with new users, about hard drive and memory.This is a hard diskThe hard drive or hard disk, is where programs, information, data, etc., is stored.

Peel the top back, and you would see a disk upon which your data is stored.

It is permanent storage.Rather like a larder fridge >> And memory, (again). What memory contains is lost when the computer is switched off.

So, you may be writing a letter, or similar.
If your computer is accidentally switched off, before you save it, you loose the letter.

If you try to end a program, without saving your work, you will be prompted to save, (or not save).
Saving stores it on your hard drive.Memory is temporary storage and a work area. Rather like a kitchen table >>


Just start to read and learn.

Ohhh wicked


And this?

Often, the last digit of a memory part number will represents the speed such as -6 = 60ns.
SDRAM speed is measured in megahertz (MHz). Speed markings on the memory chips may still specific nanoseconds, but in this case in represents the number of nanoseconds between clock cycles. To add to the confusion the markings on the chips don't match the Mhz value. Here is a conversion chart.
To calculate bytes per second you need to know the Bus Width and Bus Speed of your PC. The first thing to remember is 8-bits = 1 byte. If you have a 64-bit bus, than 8 bytes of information can be transferred at one time. (64 / 8 bits = 8 bytes)
If your bus speed is 100Mhz (100 million clock cycles per second) and the bus width is 1 byte wide, the speed is 100 MB's per second. With a 64-bit width, the speed is 800 MBs per second (64 / 8 * 100,000,000)
Rambus modules are measured in megabytes per second. Rambus modules are either 400 or 300Mhz. Because they send two pieces of information every clock cycle, you get 800 or 600Mhz. They have a 16-bit bus width or 2 bytes (16/8). The 400Mhz module speed is 1600MB a second or 1.6GB a second. (400,000,000 * 2) * 2. The 300Mhz module provides 1.2GBs a second.

Omg thanks dude, Can a mod marked this as ANSWERD

There some thing to keep you occupied for a little while.
