DRAM: The difference between DDR1 and DDR2.
About DDR1.
access DDR SDRAM or Double Data Rate memory, Synchronous Dynamic Random as a class. Integrated circuit memory used in computers. Bandwidth can be higher. SDRAM only previous data transfer rate on the edge rise and fall the Clock. (Double-pump) effectively, it is nearly twice the transfer rate without increasing the frequency of the bus before. Therefore, 100 MHz DDR system has an effective clock speed of 200 MHz, the SDRs compared. SDRAM, "SDR" is the past.
Transferring data 64-bit DDR RAM with a speed of transfer [MBCR x 2 x 64] / 8; Notes, it looks like this: (memory bus clock rate). × 2 (for dual rate) × 64 (number of bits transmitted). / 8 (number of bits / bytes) is the bus frequency. 100 MHz, DDR - SDRAM allows the maximum transmission rate of 1600 MB / s.JEDEC has set the standard speed for DDR SDRAM, in two parts sections: a specification for the first memory chip and the second is for memory modules.
Over DDR2.
In electrical engineering, Double data rate two synchronous dynamic random access memory. (DDR2 SDRAM) memory with random access and the use of technology. For storage High-speed operation of computers or other electronic devices. Other digital
It is part of the SDRAM (synchronous dynamic access memory, random). Family Technology that is a multiple of DRAM. (Dynamic Random. Access and use) more memory and an improved development compared to its predecessor. DDR SDRAM (double - data - from Access Memory, Synchronous Dynamic Random).
The main advantage of it. Is the ability to use the bus twice the speed of the memory cells, a faster bus speeds and higher highest throughputs than earlier technologies. This is the cost of high latency.
As well as to use. SDRAM, DDR2 memory cells in the Stored memory to work with takes the signal to synchronize their operations. With the external data bus. Than before. DDR, DDR2 cells transfer data on both edges increases and the decrease the Clock. (A technique called double pumping). The key difference between DDR. And DDR2 in the DDR2 bus speed is two times the memory cells to four data words per memory cell cycle can be transmitted. Thus, without speeding up the memory cells. DDR2 effectively operate as a double-speed bus. GDR.

I have 128MB PC2100 DDR 133MHz SDRAM.I wants me help a 512MB module. WRT?
-> No leg of the ram -> I should install command as well. 128MB - slot0 and 512M - Slot1 or vice versa. - I have often> should opt for. 512MB Module - Specifications? Other significant. Any> I appreciate other suggestions. Plz send me any links to crucial.com Ihave tried it but it did'nt work at the computer. MT (why I do not know) that's all
Instructions: 1) Try A different RAM vendors for online. crucial.com do not work for you. How about the manufacturer of your computer or not. 2) on your computer to 'local' Tante-Emma-Laden and says take format. What do you want. It may end up costing you a lot. But it's worth, if someone is actually working with you and make sure you end up with a solution that works.
