I have set my motherboard/BIOS to exceed the normal the bus frequency
by just a little bit. Now I would like to test my memory to see if
it is ok under the new settings.

Memtest86+ from http://www.memtest.org/ looks like a good memory
tester. You make a special floppy and boot from the floppy. So it
tests before Windows is launched.

Does Memtest86+ test memory taking into account my newly chosen bus
frequency settings?

Or does it somehow ignore most motherboard settings (like my
frequency increase) and test the memory "raw"?

No software RAM testers are that much use IMHO.Memtest86+ won't point
out anything of relevance in overclocking,none of them will.

The BIOS controls the memory timing, the memory will run at whatever
speed you've set it at. Memtest86 is as good a test as ay to see if your
memory still works. Be advised that by overclocking your system you've
given up timing margins. Just because it works when the room is cool or
when you system is under light load doesn't mean it will work if the room
gets 10 degrees warmer.

There is no such thing as "raw" testing that isn't dependant
on the host device setting the memory bus speed. In other
words, yes it tests "overclocked" settings, which to a
memory module means just another (any particular) speed,
it's all relative.

True that software testers are limited in their capabilities but to say
that none will "point out anything of relevance" is absurd and
ill-informed. Have you even tried it?

Memtest86+ is actually a good, if not the best, software based memory
tester. It is certainly a very good confidence check that nothing is
horribly awry and I consider it standard practice to run Memtest86+ for a
couple of hours before attempting installation of an OS. IME, a system
which has passed the checks - as well as a hard disk diagnostic - has
always installed and run the OS without problems.

Yes, chipset/bus freq is set by the BIOS when the machine
boots, not by the OS.

memtest86 is a very good, extensive, memory tester.
It is not a intensive (high bandwidth) as I would like,
so I wrote some in my CPUburn package. Try `burnMMX`.

Looks neat.

Does your CPUburn have any special points when compared to the cpu
testers discussed at Radifed?

Like Prime95, Motherboard Monitor's 'Heat Up', HotCPU Tester Pro
Lite, etc.

Has anyone tried Metabench? It is in late beta development and is still
free.

http://www.7byte.com/index.php?page=metabench

Is it any good?

Yes. Memtest86 performs a series of read writes to the memory and
doesn't bugger about with clock speed as a 'problem detection' feature.
If all the read/writes work, then it gets a pass, if not errors are
reported. It doesn't say 'try lowering your clock speed and see if these
errors go away'. You'll have to figure that yourself :-)

spammage trappage: replace fishies_ with yahoo

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. To jump to the end
of the story, as a result of this I need a bone marrow transplant. Many
people around the world are waiting for a marrow transplant, too. Please
volunteer to be a marrow donor:

I really haven't had much time to look around. If I had the
time, I'd be releasing `burnRAM` [need win32 port] and `burnP7`
[needs some signals work].

It's very easy to get "100% CPU utilization" according to
the OS. `jmp $` or `while(1);` will do. The OS always has
something to run (not the idle thread), so it thinks it's busy.
If you can't get 100% (MS-Win9*), it's a priority issue.

But this is only around 70% of max power draw. Not all the
chip circuits are kept busy. I've crafted my burn* pgms in
assembly (natch!) to try to keep as much busy as possible.
Without any constraint of actually doing useful work!

Some programs can keep the CPU 100% runnable but really not
be compute-limited. Doing useful work is a bit of a limit.
I stuff useless instructions in. SETI@home was notorious for
very odd times for work unit completion (memory fetch bound).

I _don't_ claim my pgms are the hottest possible. I'm sure
that Intel and AMD use better ones as part of their CPU
manufacturing testing. But those are deep dark secrets.
Mine is Open Source.

Press "c" "2" "3" "Enter" to run all eleven tests.

Yes.Next to useless and not worth the download let alone running.

Window's itself is a good test of hardware memory.It will balk if
there's anything wrong usually throwing up a,"Registry" fault.
Why some people defend a piece of software that they get for free I'll
never know.Hardware RAM testing machines run into the thousands.Go
figure.
PS
Best RAM test if the user suspects a fault is to swap with a known
good stick ;-)

Oddly enough I seem to recall a Shep from the K7S5A boards, where
Memtest86 was the recommended tool to identify motherboards that had
"issues" with the higher speed Athlon T-birds. Maybe a different guy...

Defective software, drivers, and other MS-Windows
cruft can also throw lockups, BSoD & Reg.errs

When these happen, you don't know if it's hardware
or software. Best to have some simple testers that
can rule out hardware. Testers can usually be more
intense than apps or OSes.
