ECS K7VMM+ v3.1 with AMD XP2000+ CPU? No boot?

[Noozer]

I just finished swapping out a 1Ghz AMD CPU with 133Mhz bus, replacing it
with an AMD XP2000+ CPU. The computer does not boot... Fans/drives spin up
but there are no beeps, etc.

I flashed to the latest BIOS tonight. PC booted fine after this. I then shut
it all down and swapped the CPU and cleared the CMOS using the onboard
jumper. This is the point I'm at now.

Any ideas why this board won't boot? ECS says it should work with up to at
least an XP2100+

Thanks!

Ps... Off to try a new PSU and possible swap memory.

.... but will it work with a T'Bred XP2000 or only a Palomino XP2000?

You do not need different memory... the memory bus is the same speed
as before, so since it worked previously at 133MHz, the new CPU isn't
going to change that.

Power supply problems are common in systems build to a low
price-point, with cheap boards like that one, quite often a cheap
power supply too... but we can't assume what power supply you have,
you'll have to tell us.

Core is markedAX2000MT3C, AGOIA ... 1.75volt "Athlon XP"

Old part was A1000AMT3C, AXIA ... 1.75volt "Athlon T-Bird"

...both running the same voltage so I assumed they would be interchangable.

Didn't think so, but I've seen less related items make a difference.

Was an ATNG PS300S - 15A 3.3v, 29A 5v, 11.5A 12v, .5A -5v, .5A -12v, 1.5A
5vSB. This was a cheapy supply that I've had for a while.

Now a Macron ... don't have the ratings handy. Definately better than was in
there before, but how much is another story.

Life was much simpler when "if it fits the socket, it will work" was the
motto.

Thanks!

A Palomino... rules out that possibility

Voltage has no bearing on it, all modern boards have programmable
voltage regulators, generally they can do at least 1.3V-1.85V, often
up to 2.0V, sometimes even wider ranges. The issue is of BIOS
support, and I believe the T'Bred needs slightly different signal
strength, so on some boards it might be marginal, though in such a
case the manufacturer wouldn't (shouldn't) claim it's supported at
all.

You might take voltage readings with a voltage meter at the power
supply leads, or at least in the bios, if possible. Low 3V, 5V, OR
high 12V are signs of a problem.

Tue, but that usually meant buying a new motherboard more often.

When you cleared the CMOS, you did so with the power supply AC input
disconnected for at least ~10 seconds beforehand?

If you're trying to use multiple memory modules, remove all but one,
and if the board has a jumper to change FSB speed, see if it'll post
at 100MHz FSB & memory.

Googling found conflicting results so I wasn't sure what core it was.

At least being the same voltage would make it a safe swap where parts
wouldn't burst into flames.

All the parts were purchased at different times... Basically a frankenstein
of leftover parts. I was trying to use up all the best of my spare parts in
this machine, but it has not gone well.

Might help if my meter was more reliable than my PSU. : )

Didn't disco from the power, but switch on PSU was off - I prefer to keep
the chassis grounded.

No luck @ 100Mhz either. Currently got it running with a 1.333Ghz TBird and
a single stick of 512meg. Wouldn't boot with a different 512meg stick so I'm
starting to wonder if it might just be a touchy mainboard.

When I have time I'm going to pull it apart and bench run it to test all the
components.

Thanks for the help... Machines going to have to stay how it's running for
the moment.
