Hi Si

Apologies for the delay in replying again. As you will see, to get all the
info down in black and white takes a fair old amount of time.

Here's my system spec (I use this PC for multi-track audio recording with
Steinberg Cubase VST 32 v5.2 and/or Cubase SX 3).

The fans and drives are quite noisy, as would be expected given the numbers
involved, which for an audio recording PC is normally a problem, but the
whole machine iteslf is isolated and therefore not a problem when in use.

I don't think there's anything more I can tell you about my system.

If you try the manual memory settings I have listed, plus the 0.2v
overvoltage on your RAM (check your memory's packaging first! - sorry, but
you're on your own if by any chance it should burn out because of
over-voltage. It's always a slight risk, but it was recommended by Corsair
on the packaging my RAM came in, and has worked for me to date), you should
achieve stability. There is a proviso though... your existing OS and
software installation should have been stable to start with (I assume it was
with your old CPU from what you've previously described) AND you're not
overclocking anything (I assume you're not from what you have said - but in
general overclocking terms, not particularly specific to the 8KNXP, unless
you lock the AGP and PCI frequencies to 66MHz and 33MHz respectively, every
1MHz increase to the CPU's base FSB - normally 100MHz for P4 but multiplied
within the CPU to give 533 or 800MHz actual speed - will increase the AGP
frequency by a further 0.66MHz and the PCI bus frequency by a further 0.33
MHz. Whilst most modern AGP cards are quite flexible in this respect, not
all PCI cards are and some might start to fall over causing random reboots
with a moderate PCI frequency increase to only 37MHz or so.). The 8KNXP
like many other modern boards has been designed for overclocking to some
extent, and therefore has the ability to lock AGP and PCI frequencies to
66MHz and 33MHz irrespective of how fast you can push the CPU and Memory.
SATA controllers also suffer from overclocking settings and o/c is not
recommended if you are using SATA. Personally, I've tried overclocking with
a degree of success a long time before getting this board, and yes, it's a
bit of fun to get something for nothing and to see how it's done, but with
this particular PC, I can't afford for it to fall over in the middle of a
band's live performance at a gig, so stability is paramount, so apart from
the memory timings which I found in December 2003 on the Net and can't take
credit for, I haven't made any special provision.

You might find swapping any PCI cards you have around to different slots
might help (but as you've run the baord for some time, I doubt that this
will help).

The only other thing I can think of, is a dodgy driver - you should always
try where possible to use drivers that have been certified (signed) by
Microsoft. I know it's not always possible, but Microsoft have cleverly
largely dodged the issue of being accused (as they have been a lot in the
past) of producing a faulty OS when quite a lot of the time a faulty 3rd
party driver was to blame. That's why the message pops up asking you to
confirm that you want to use an unsigned driver, thereby passing the
responsibility if the system fails to you. You always have System Restore
or the last of the regular backups you took ;-/ Graphics card drivers are
probably the most common culprits in my experience - many graphics card
manufacturers - Matrox in particular - used to tweak a few settings via
software drivers (probably still do in a more sophisticated way) to give
their cards the edge, and although I like Matrox cards a lot, a few years
ago (pre-XP) they used to give me some interesting moments.

I hope the information I have shared here helps you sort out your problem.

Regards

Nick
