Hello every one,

If there is an ERROR in a non-parity memory, how can I feel about the
error?

can you give me an example about how the user can see the error which
is occurred in memory?

Possible symptoms:

An application will crash.
The operating system will crash. (Blue screen or STOP error.)
Programs fail to work correctly (memory allocations fail because data
structures are corrupted).

To test, run this program for at least four hours. The program will
stop if it sees an error. If an error happens, your computer is
not stable, and should be fixed.

Orthos uses a large portion of system memory (uses >700MB on my 1GB
system) and runs the same code as Prime95 and its torture test.
It detects calculation errors when they happen, and is a sensitive
test of your CPU and memory.

memtest86, run overnight. Should be 0 errors.

Alternative: memtest86 at memtest86.com (Free version)
advantages:
- Comes with it's own OS environment, so it will run even if
Windows / Linux is corrupted on the PC.
- Runs memorytest only. So any error shown will actually point to
a memory error, not to a Windows problem :-)
- Actually exercises the memory system.
- Very compact. (Fits a 3.5" diskette)

Unhappy.

Replace the memory with ECC memory.
 
thanx all of u..

if these occured in non-paity memory.. what about parity memory?

*** Hardware malfunction
NMI: Parity Check / Memory Parity Error
Call your Hardware Vendor For Support
*** The system has halted ***

I presume that is for a multi-bit error, that could not be
corrected.

There is a description here, for how Linux handles it.

I don't have any computers equipped with parity here, so
haven't seen any of those error screens.

On a UNIX system at work, that had correctable errors, the
machine slowed down, and the system log was filled with warning
messages. But the machine continued to work, until it was
repaired. I don't know what would have happened if it found
an uncorrectable error.

That's ECC, not parity, and can normally correct all single bit
errors. It can detect multibit errors, but not correct them.
