Please help !! My System Has A Memory Error But It's Not T..

I need help !!

I have a PIII system, 1.3 GHZ - actually it's a Celeron. I have 3 RAM
modules on it, each 512 MB, for total of 1.5 GB.

Lately my system acted strangely, so I ran a battery of memory tests,
both the Norton Diagnostic and Memtest told me that the sytem RAM is
faulty.

The faulty memory location is at 14XXXXXXX - sometimes 144XXXXXX,
sometimes 145XXXXXX, sometimes 146XXXXXX, everytime I reboot the
machine, the "exact location" changed.

Since it supposed to be the RAM fault, and I wanted to see which one
is at fault, I change the location of the RAM module. To my surprise,
the "faulty location" stationed somewhere 14XXXXXXX - even when I have
switched the location of the 3 RAM modules.

Now I got curious. So I plug in a 256MB module, and unplug the 3 512MB
module, and ran the memtest (and Norton Diagnostic) again.

Lo and behold, the "faulty location" is at 14XXXXXXX !!

So, now I am facing with a "faulty memory" problem but it ain't the
RAM !

Can anyone please tell me what's going on ?

I've even eye-balled and cleaned the RAM module sockets, but the fault
is STILL THERE, at 14XXXXXXX !

What else I should do to locate the origin of the error ?

I know that it may be my MOBO, but I just want to know WHICH part of
the MOBO is acting up.

Many, many thanks in advance !!

Run memtest86 on your system with a single stick of RAM in it at a time.
Then try two.
Then all three.

You should be able to track down where the problem lies.

Look at the capacitors (those tall, and not so tall, cans), especially
those near the memory slots. If their tops are bulging, or brown goop
is oozing out, then that's your problem.

Sounds like a bus error. Is your PSU good? Mobo properly grounded?
Bad caps? or noise on the 3.3V line?

Most of the things you identify would not always point to the same
location.

Can be. Not all errors are within set locations - the error may be at
another level within the addressing logic, rather than within the data
of certain address cells.

OK. At this point it's worth mentioning that the memory system isn't
just the RAM itself, but also L1 and L2 cache (in processor) and the
support logic of the motherboard's chipset, etc.

>So, now I am facing with a "faulty memory" problem but it ain't the RAM !

SiS mobo chipset? Specifically, SiS 650 I think? Always test 5 in
MemTest86, and OK in tests 0-4 and 6-7? BT, DT.

>What else I should do to locate the origin of the error ?

Swap-test processor, if possible, and check things like:
- RAM timings in CMOS
- exclude overclocking
- bad motherboard capacitors
- inadequate PSU (<235W, for Socket 370)

Unless it's capacitors, the parts involved will be surface-mounted and
not amenable to soldering-iron-mediated replacement.

I thought he'd done that, but if not; check mobo's manual - not all
will tolerate the electrical loading of 3 x 512M DIMMs.

Also, try putting the slowest DIMM in Slot 0. If mobo auto-adjusts
timings as per the first SPD it sees, you want that to be the slowest
one, so that timings will be conservative enough for the slowest RAM.

Another issue is whether or not the RAM is registered. Usually when
systems have lots of RAM, it's required that it be registered to avoid
timing issues.

The DDR memory bus on a PC is not ideally terminated - there will be
reflections and other transmission line effects. I've seen quite a few
boards where the maximum memory bus speed that could be used without
errors would change noticeably depending on which slot(s) were used
for one or two memory modules was placed. With three modules, the
memory bus will be relatively heavily loaded and this is something of
a worst case situation, especially if the modules are double sided (a
common case for 512 MB modules). I think one of the other posters
pointed out that sytems that require large amounts of memory generally
use registered memory as this allows more time for the data signals on
the memory bus to settle.

I ran memtest86, and did what you say. Ran ALL the tests, standard and
extended, and memtest86 reported NO ERROR.

And when I went back to Windows, it acted strange again. Ran the
Norton Utility Diagnostic, and the memory error still appears.

Dunno what's going on. Just running out of options here !

Thanks for your help !!

Did that, and the problem persists. Dunno what's wrong. Now at least,
after running memtest86, I am sure that there's no problem on my RAM
module. Checked the mobo's spec, no problem for 3 X 512 MB ram module.

I know something is wrong, and the only thing is that I dunno what it
is, and this is bugging me !!

I can "see" all the RAM on the bootup, because the mobo does read ALL
the 1.5 GB of the RAM. I assume all the RAM is registered. Am I right
?

Chris Brady's memtest86 is an excellent program to exhaustively
test all memory cells. Unfortunately, it is not very intensive
(running maximum bandwidth).

My burnMMX program is not nearly so exhaustive, but it tries
to be intense. I have a new `burnRAM` pgm that is even
higher bandwidth, but I hate porting to MS-Win32.

You might see if you can keep `burnMMX P` running for a few
hours, or how quickly it stops (when it finds an error).

Does your motherboard share memory with onboard video?

What about other BIOS settings such as "OS/2 Onboard Memory >64M" or
"memory holes"?

Is your faulty location 14XXXXXX or 14XXXXXXX, ie 6 or 7 Xs? Can you
see anything occupying this address space when you go to Control Panel
-> System -> Computer -> Properties -> Memory?

AFAICS, 14XXXXXX = 320MB and 14XXXXXXX = 5120MB, so this makes your
test failure with a single 256MB module appear very strange.

Have you tried the Norton test with just one memory stick at a time? Two
sticks at a time?

It is possible that you have a motherboard problem and that the memory is
fine. In many systems, signals along data and address lines couple to give
spurious signals on [seemingly] random at [seemingly] random times.
Sometimes this is data pattern related.

Also, was anything else running in the system when you ran Norton? If this
is a Windows program, have you tried it in safe mode?

I don't much care about NT/2K/XP, especially XP.

That's interesting; more on that, please? I never did figure out what
"registered" RAM was and why it may be worth the extra cost.

Look also for MemTest86+ at a different URL...

http://www.memtest.org/

AFAIK MemTest86 is open source, so anyone can delevop it further - and
the folks at memtest.org have done that, compared to memtest86.com

Also try www.simmtester.com

When using MemTest, try All tests (0-11) - press C, 2, 3, Enter.

>I ran memtest86, and did what you say. Ran ALL the tests, standard and

That suggests the processor seating and unseating the modules fixed
the problem. Dunno how confident I'd be on that, tho.

>And when I went back to Windows, it acted strange again. Ran the

Is Norton Utility Diagnostic running in Windows? I'd have little or
no confidence in that, if so.

It may be that other "untestable" hardware issues are making Windows
throw errors, etc. (or active malware, or course).

http://cquirke.mvps.org/9x/bthink.htm refers.

OK, that doesn't really suggest an advantage...

>http://www.theddrzone.com/faq.php

....but this clarifies; looks like a scalability thing, if you are on
the edge and can't get "normal" RAM to run reliably in large
capacities, registered RAM may help stability.

So to build a PC with (say) 256M registered RAM would be utterly
pointless, but you might find recommendations to go registered for, I
dunno, 2G+ total capacities.

I wonder where that edge is, in 2004?

The "edge" these days seems to be around 24 chips per memory bus (ie
dual-channel gets your twice as many), though sometimes you can load
it up to 32 chips. I've seen a few modern setups that will allow you
up to 48 chips on a single channel, though most tend to reduce your
performance if you load the bus up by that much. Unregistered memory
modules are available with anywhere from 4 to 16 chips on them.
Typical modules have either 8 chips all on one side or 8 on each side
of the module (16 total), though certainly other combinations do
exist.

These days you're mostly looking at 256Mbit or 512Mbit chips, though
1Gbit chips do exist for a bit of a price premium. Using 512Mbit
chips you can pull off 3GB on a dual-channel setup with unregistered
memory without too many difficulties, ie a pair of 1GB DIMMs and a
pair of 512MB DIMMs.

Generally speaking, registered memory is mostly used for servers while
unregistered memory is mostly used for desktops.

My problem may or may not be anything like yours...I have a PIII I'm
trying to upgrade with a powerleap 1.4 celeron, and add memory (three
sticks on an Intel SE440BX-2 mobo). I got all kinds of memory error
beeps and spent a month trying different combinations before figuring
out the system, being 5 years old, needed a new battery!
