 As noted in the introduction, there''s a virtual alphabet soup of memory types: SDRAM, EDO, FPM, SIMM, and DIMM. simmmemory It certainly can create a great deal of confusion. RAM itself stands for "random access memory," meaning the CPU can access any memory address without reading all addresses before it. (ROM—read only memory—is random access, too, but you can''t write to it). It gets worse, because memory comes in different speeds, and some types don''t work in some systems. Here''s the rundown on the three simmmemory memory types used in today''s systems.... SDRAM. Synchronous DRAM SDRAM''s speed is typically measured in MHz (for example, 100MHz), although you do see references to 10ns SDRAM ("ns" stands for nanosecond or one billionth of a second). SDRAM for PCs comes in DIMMs. These refer to SDRAM DIMMs rated at different memory bus speeds. For any CPU running at a 100MHz bus speed you should get SDRAM. Some future motherboards will support SDRAM. Although there''s a price premium, SDRAM will run in a PC100 system. How do you know it''s time for a memory upgrade? There are several signs indicating it may be time to upgrade your memory. If you see your mouse pointer turn into an hourglass for significant periods of time, if you hear your hard drive working, or if your computer seems to work more slowly than you expect, the reason is probably insufficient memory. When the memory is full, your system transfers data to the hard drive. This is called swapping. Since the hard drive is considerably slower than DRAM, your system seems slower altogether. simmmemory don''t know the model number of my computer, how can I get the right RAM? Please provide the following information simmmemory in order to determine simmmemory what memory you need. You can send it in an email to support@4allmemory.com. How many memory slots simmmemory do you have? (It will generally be 2, 3 or 4) How many sticks of memory do you have in it now? How much memory is currently installed? (i.e. 16MB, 32MB etc..) What is the length of one stick of memory? (It will generally Please provide all of the numbers off of any stickers on a piece of memory. Look at one of the little black chips on the memory stick and provide all of the numbers off of one chip. (it is generally easier to read the chip numbers if you hold it under a bright light) 4 All Memory.Com warrants that all products are free from defective material and workmanship and, subject to the conditions set forth below, agrees to repair or replace any part of a product that proves defective by reason of improper workmanship or materials without charge for parts and labor.
