Deeper Briefly Comprehension about PC133 Memory

By Imanuel Henry

Memory is required to run various programs and giving the smooth way of uninterrupted computer operation. What makes a computer or laptop run fast is based on its processor speed and the amount of memory.

If your computer is run out of memory, it can result in low speed and even application crashing. Along with the need from the market to get the faster and powerful computer, the processor and memory has to be developed.

Memory has developed into many types and series. In 1996, SDRAM were invented. SDRAM (Synchronous Dynamic Random Access Memory) delivering the data at high speed which is using an interface that have been synchronized to the CPU clock.

In SDRAM modules, the kind of memory is using �PC� and the numbers that refer to the speed of the system's front side bus (FSB). The higher the number, the faster the system's FSB.

The FSB is the memory bus between the Memory module and Processor. It is the main information highway in the PC system. The faster the bus, the faster the data is being transferred between memory and processor.

Definition

The fastest and final SDRAM standard that approved by JEDEC (Joint Electron Device Engineering Council) is PC133 Memory . This memory runs at 133MHz, 3.3V voltage, and 64-bit wide bus. It delivers 1064MB per second bandwidth.

The PC133 Memory available in 144 pin SO-DIMM and 168 pin DIMM. It is backward compatible with PC100 or the slower ones, PC126 or PC66. If the PC33 Memory ran on the 100MHz FSB, the memory will operate as fast as 100MHz, and so does if it works with PC66.

The backward compatible phrase is mean that you can add faster memory to a computer that designed to run slower memory. But the PC133 Memory cannot be replaced or mixed with newer generation as DDR, RDRAM, or DDRRAM.

PC133 Memory is fulfilling the Intel' requirements and compliant with Pentium II, Power Mac G4, and AMD Athlon based systems.

Identifying PC133 among others

The PC133 memory speed rating is 7.5 nanoseconds when runs on 133MHz FSB motherboard. And this chip is often referred as �-7.5�. The PC133 Memory is identified with �-65�, �-7.5� or �-7� when you reading the last two digits on the chip part numbering. The �-7� means the minimum operating clock cycle of the device.

Conclusion

PC133 Memory module is different with its predecessors. The AC timing specification is resulting that the PC133 Memory is allowed a system bus to run at 133MHz FSB (Front Side Bus).

Adding faster memory probably cannot faster your system to run. The computer cannot be speed up if there are any components in the computer that run in slower speed.

Please beware if your supplier does not giving the clear information about the memory module performance. Check it first to the system manual or look into the system to find the compatible memory.

When you installed the PC133 Memory in the old computer and it cannot work, probably it is the computer faults, and not the new memory does.
