Hi,

I've just inherited an S2460 and after a bit of research, I've found that
the MP 1900 is not the highest performing processor that the S2460 will
accomodate (unofficially). And for the modders, yes, I am aware of the 5V
molex mod to the ATX connector.

Does anyone have this board and are you running an MP CPU at higher than
Tyan's rating., or using XP chip(s)? I was contemplating dual 2800 MPs for
this board, but if XPs have less current draw, perhaps they'd be a better
choice...? Thanks.

I built a few systems using this board, initially with
processors in the 1600+ to 1900+ range. Some of them
were later upgraded to 2400+ with no problems. I attempted
to upgrade another to 2600+ but the system would only boot
when the second processor was pulled - I ended up settling
for 2400+ in that system too.

XP's and MP's at the same rating (eg., 2400+) are
identical except for a few trivial differences and
hence use the same amount of power and generate
the same amount of heat.

Note also that a pair of Opteron 242's will set you
back about the same amount as a pair of MP 2800's.
If you can afford another $400 to $550 for a dual
socket 940 motherboard, you should give it serious
thought - an Opty 242 dualie will run circles around
an MP2800 dualie in just about everything.

PSU issue maybe? Also -- and as I understand it -- the newer Bartons are
multiplier locked. Is this accurate? If so, I'd be running the Bartons
underclocked, so maybe a slower unlocked 333MHz CPU would provide the same
results. I'm not planning to overclock them per se, I'm just trying to get
max. performance from a 333MHz CPU on a 266MHz FSB.

Okay, that solves that.

The board was free and I have all but the CPUs and memory. Going OEM CPU and
aftermarket HSF will set me back less than $400 (not including RAM). It's
just a "let's see, what if" project. I've had no previous experience with
AMD so it'll be fun to see what happens. Thanks Rob.

I think I eliminated that. Even when I disconnected
the hard drives, DVD, etc., the system wouldn't POST.
I've also used the same PSU to drive a pair of 2800MP's
on an S2466 loaded with 4 SATA drives, a DVD burner,
and 4 GB of RAM.

The Barton 2800MP's have a 266 MHz FSB. Probably just
recognition by AMD that every Athlon MP motherboard uses
AMD's 760 or 760MPX chipsets - which support only 200
and 266 MHz FSB.

And yes, the multiplier is locked.

Turns out my price comparison was wrong anyway. I was looking
at prices for the Opty 142, not the 242 - which costs significantly
more.

I have had MP2800+ CPU's running in my TigerMP Since Feburary 2004. Details

It's been perfectly stable and reliable for me.

Sounds promising. Thanks!
