Memtest report error... John-Y 09-14-05

I recently used memtest86 after experiencing many serious system
instabilities (random file corruption, system crashes). Basically memtest
would report thousand of errors in a matter of minutes.Turned out the the
problem was caused by a faulty Bios setting (memory was set to 'performance
mode'. Whatever that means) After setting the value to default, the problem
was corrected.

But now I'm still getting an error. A single one this time. Happens on test
7 always at the same address (0000006952c).
The error occured semi-randomly it seems (but always at the same address)
every 2 passes or so on average.

So I wonder if this is normal. Is this a sign a defective/"incompatible"
Ram?

Any one error from any semiconductor inside the computer -
and your system has crashed. Not only should memory test just
fine every time, but it should also test just fine even when
heated with a hairdryer on highest setting. If in doubt, then
look at the operating temperature from memory datasheets -
well above what your hand (or hair) will call comfortable.
But a defective memory sometimes may fail Memtst86 (and other
memory tests) only when at elevated (and perfectly normal)
temperatures.

Heat finds weak memory before it causes hard failures
later. Unfortunately some never learned this and install more
fans to cure a defective semiconductor problem. Pig's Heaven
to memory is a temperature at the uppermost and lowermost
temperature numbers on that datasheet. Any memory that fails
at the 'paradise perfect' temperature of a hairdryer is 100%
defective - even if only one memory location fails 1 in 100
tests. Hairdryer tends to find defective (intermittent) memory
faster.

To work, every essential digital IC in a computer must work
correctly every time - which is why we use digital logic and
don't use analog logic circuits. In computers, no tolerance
for digital logic errors - especially from memory.

You should receive absolutely NO errors no matter how many passes it makes.
It sounds like the RAM might be defective. You might also want to change the
BIOS setting from 'default' to custom and manually enter the timings your
RAM is rated at.

Thanks to Alceryes and w_tom for the informations.


I brought the PC to the place from where I got it so they can have a look a
it. I explained what's wrong it,the error reported by memtest and
everything. Guy said: "all right I'll have a look". Anyway, a week later the
guy tells me he fixed the problem, said it was "related to gfx card". Well
he fixed it my a**... Problem is still present.(at least he didn't charged
me.)


But now,I'm observing some other problems...So far, this is what I've seen:

-The PC does not always boot. That is, it "powers up" fine but the bios
won't execute.So nothing happens.No choice but to turn off and restart. This
seem to happen more frequently when the Pc is "cold" (when it's been off for
more than an hour iow)

-After the above failure to boot, it'll report: "CMOS checksum
error.Returning to default". Regardless, after a while the problem will
reappear.

-Memtest fails the "Memory sizing - Bios All" test
(configuration,option3,option2) Reports nothing but errors.

-And of course the error reported on test 7 at address 0000006952 like I
said above...




Does the above shed new lights on what may cause the problem? And no, I
haven't changed the Ram module yet...(I kinda hoped the "repair guy" would
do so)

Forgot the most important one:

-PC crashes randomly.And this under almost any software
environments,including during installation of Windows XP,something I've
never experienced before. On average,it'll take 15 to 30 minutes to get a
crash.
