mb: Kt7 (non-A)
bios: a9
cpu : axmd 2400 fjq4c (fsb266, 35W)

tried core V up to 1,9 (32grC)

I simply can' activate any multiplier above 12 (freq given by MBM 5)

(In a Fresh Diagnose cpu run it was ranked twice as high as a P4 1,6GHz
!!!??? Then run @1200... wasn't that strange?)

Can MBM 5 be wrong?


Can something be adjusted (checked) to get more outa the cpu?

The board doesn't have control for the fifth multiplier bit, so unless it
pulled high you won't get above 12.5 with a standard XP. I've never used
an XP-M, but if it uses the L3 bridges to set the multiplier, then you
must have the 5th bit high. It will then default to a 20x multiplier (bios
shows 12>above or something like that). So what is the state of the laser
cuts on the L3 bridges?

Try a google search of this group for kt7 xp-m. it has been discussed here
before about the mod you need to do. Here's something.

You could try an Athlon XP-M 2500 or 2600+.

I had a 2500+ running at 20x100MHz in my KT7a, but now running at
2261MHz quite happily.

You'll need to do the socket wire mod:
http://www.ocforums.com/showth read.php?s=c8f573747b2926eb4a5 c6fa49424...

Then 12.5x will hopefully be mapped to 20x in the bios, as in Wes'
multiplier cross ref.
------------

Note that this is nothing more than pulling socket pin AJ27 (5th
multiplier bit) high to gain access to the upper multipliers.

Does this mean that it would be considerd to be multiplier locked?

Pull 5th bit high?

L3 bridges... don't know yet.

I used a single strand form a ribbon cable. I'd guess that anything larger
than 30 guage would be too big. Note that wire gets bigger as number goes
lower. IOW's 30 guage is a lot smaller than 24 guage (common telco wire,
cat 5 wire, etc.)

Sorry. I don't know what it is. To pull AJ27 high, you can;

1) Cut the L3-5 bridge on the cpu.
2) Connect AJ27 to vcc pin next to it a) on the cpu, b0 on the MB, c)
anywhere you can find them.:-)

You can use wire, conductive paint, or whatever you can find that will
conduct.

What could be the safe max freq for the xp-m2400+ (heat, stability etc.) ?

I don't have the need to push it to it's limits.

It will vary from one chip to another depending on PSU, cooler, etc., but
the fastest stable speed you can get at 1.70v with still low temps sounds
good to me for 24/7 operation. That might be 2400MHz or less or more.:-)

At which max speed would you _bet_ it could run stable at 1,7V ? ;o)

....so to know where to start.

psu 250w (early athlon approved)
basicly laso low consumsion (ati graphics)
fan TR2-M3 ( => XP 3400+)

Saw that my cpu is one of those that can take 100degC

I wouldn't trust that 250W cpu to keep it stable at any speed. The TR2-M3
is a good choice and should be ok even if you take the voltage up to
1.85v. Any guess I made as to how fast you can run the cpu stable at 1.7v
with that PSU is about as good as a drop of rain on a hot sidewalk, but
since you insist, I'll throw out 2000MHz. Now, assuming a decent core and
a larger PSU, I'd guess close to 2400MHz. I'd consider myself lucky to
keep it stable at stock voltage and speed with that PSU. For under $20 you
can get a 600W PSU, and that's what I'd do first. Or even a 500W for less..

When making pin-bridges I hade lost my notes. I guessed at the pattern for
24x and got it right.
Starting with 1,75V it started. But, at restart nothing! (temperature
rised?)

At 1,8V and 1,85V same thing. Boot but lock at first windows screen.

Just to try I went for a lower voltage, 1,65V and it started at first try.
Watching MBM5 meters the cpu temp fell from 43degC to 39deg. Possibly they
run better at an optimum temp!? ...at least this, but who knows what
happens next?

At least it's up and running at 2400, 1,65V and ~39degC.


Thanks!

So far it has started perfect both at cold start and restart from "hot" at
1,65V. Temp runs stady at 38-40degC.

Either my psu doesn't deliver steady at >~1,75V
or the cpu performes more steady <~44degC
