 DIMMs (Dual Inline Memory Modules) look a lot like SIMMs, but they come in a 168-pin format. They are usually a faster and higher-performance memory than SIMMs, and are used in Pentium PCs. They come in capacities ranging from up to 64MB and beyond. Step 4: Parity Versus Non-Parity Chips A SIMM or DIMM usually has nine chips of memory on it. Eight of those chips are used for the memory itself. The ninth chip is called a parity chip. The parity chip is used ddrraminformation for error checking, to make sure that the other chips aren''t making any errors. Some computer systems require parity chips, while others do not. In general, Pentium-based computers and certain 486s don''t require parity memory. Parity memory usually costs more than non-parity memory. Check your PC or motherboard''s manual to see which kind of memory your PC requires. What does the CL stand for on memory chips? CL stands for CAS Latency. ddrraminformation When a module is labeled CL2 it means there are only two clock cycles before the module can send the first block of data. CL3 means there are three cycles before the first block of data is sent. Cl2 is considered to be a small percentage faster than CL3 modules. PC100 and PC133 modules are manufactured as both CL2 and CL3. You will need to check with your system''s requirements to see which option is compatible with your system. Does ddrraminformation it matter which slots I plug my new module in? In general, you will get the best performance if you put the largest module (in megabytes) in the lowest-numbered slot. For example, if your computer comes with 32MB of removable memory and you want to add 128MB, it would be best to put the 128MB module into slot 0 and the 32MB module into slot 1. My system will not boot after installing your memory? Are you getting ddrraminformation an error message on the monitor? If it states a Non-System Disk error occurred, check to make sure that you do not have a non-bootable disk in the floppy drive, or even the CD-ROM drive if your system can boot to the CD drive. What is Buffered Memory? Buffered memory uses a Buffer chip to boost the clock signal sent across the memory module so that the clock signal is seen as a clean, sharp signal across the entire module. It eliminates chances of memory errors in data sent or retrieved from memory. It is commonly used in larger capacity Fast Page Mode or EDO modules. Buffered modules have a different keyway in the contact edge and can only ddrraminformation be used when the board supports Buffered modules. Unlike Registered ddrraminformation modules, it is not interchangeable with Unbuffered modules. Can I mix different speeds? PC600, PC700, and PC800 are three different speeds of memory once available for RDRAM (Rambus dynamic random ddrraminformation access memory) modules. Of the three, PC800 modules are the fastest, and PC600 modules are the slowest. (PC600 and PC700 are no longer being produced ddrraminformation by any manufacturer) Would you like to find ddr, simm or dimm memory but aren't sure where to look? Search no further.
