System Memory | Parity Errors ] I am receiving a parity error as soon as I memory parity error fix boot up the PC
Explanation: A parity error is occurring on a PC as it boots up. The parity error will typically occur asMemory Parity Error Dell
soon as the system completes the power-on self test; the memory count that is performed will typically pass without any problems being recognized. In some cases, when booting up Windows 95 or Windows NT for example, the parity error will memory parity error hp not appear until the graphical user interface of the Windows operating system itself comes up on the screen.
Diagnosis: The most common cause of parity errors when first booting up the PC are incorrect configuration or using the wrong type of memory. It is unusual for an actual memory failure, of the type that parity checks for (meaning, you wrote one value into memory and read back another value with a bit changed) to be encountered at the start of memory parity check error booting, although it is possible. Recommendation: Look on the screen to see if the system is giving you any sort of memory address that indicates where the parity error is occurring. Reboot the system and see if the same address comes up again, and then reboot a third time. Take note of whether or not the memory location changes, and then continue below: If the parity error is coming up as soon as the BIOS tries to boot, and especially if it fails at memory address "0000" consistently, this is a dead giveaway of trying to use non-parity memory in a parity system. Make sure that you have used real parity memory if you have parity checking enabled. If you are or were running with parity checking disabled, double-check the BIOS setting to make sure that it is still set as disabled. If it is enabled accidentally, parity errors will result. I have encountered a defect in the Abit IT5H motherboard, version 1.5, which will cause it to fail when using parity memory--it just does not work in this board due to a design flaw. Every time parity is enabled a parity error is generated immediately at boot time. It is possible that other motherboards may have similar problems. The only solution is to replace the motherboard or run with parity checking disabled.

First, we'll examine what memory is, where it memory parity error fits into the PC architecture, and how it works. Then we'll look at the various types of memory, speeds, and packaging of the chips and memory modules you can buy and install. This chapter also covers the logical layout of memory, defining the various areas of memory and their uses from the system's point of view. Because the logical layout and uses are within the "mind" of the processor, memory mapping and logical layout remain perhaps the most difficult subjects to grasp in the PC universe. This chapter contains useful information that removes the mysteries associated with memory and enables you to get the most out of your system. Memory is the workspace for the processor. It is a temporary storage area where the programs and data being operated on by the processor must reside. Memory storage is considered temporary because the data and programs remain there only as long as the computer has electrical power or is not reset. Before the computer is shut down or reset, any data that has been changed should be saved to a more permanent storage
