have find the time to play with this sys,
tried to set 5th bit with the u-wire in
the socket, but then it won't post..

i was thinking to set multiplier in
bios to 7 + wire to give me 15, but
it doesn't work..

when i removed the wire, sys booted
normaly..

anyone tried this with success??

after reading John Caracich's
workarounds, have solved all the problems
and i can say that Barton 2500+ can be
used on kg7(r/lite) to the full potential..

first, i have put u-wire to connect fsb1 pin
with vcc (AH30 - AK30), just in case,
after reading about timing problems..

then i have put back the wire to connect 5th
bit with the ground (AH26 - AJ27), but there was
again no post..

the solution was, after reading about multiplier
workarounds and bios driven buffered circuit,
to change the multiplier to 13x or 15x..

now, this cpu is humming rock solid at 16x150 mhz
(2,4 ghz) at default voltage..

bios is ds, multiplier settings in bios is set to
above 13 (set this before puting the wires)..

cheers

just for info, SiSoft Sandra Arithmetic Benchmark result
is 8891 MIPS and 3594 MFLOPS, idle temp is 39 degrees C..

hope this helps

What happens if you just slap the 2500+ CPU in there and clear the CMOS with no modifications

it posts without any modifications,
if that's what you ask..

you have access up to 12.5x multiplier,
11x is default..

I just got back getting one (2500+) and installed it, cleared the CMOS and it booted at 500. I set it as 11x166 4:4:1 and it shows up as the correct megahertz speed but it shows as Unknown CPU Type in the BIOS and Windows. Should I be concerned about that? I don't like how it's not showing the processor name. Also, should it be set at 4:4:1 or 3:3:1? I know almost nothing about this sort of thing.

I'm thinking of exchanging it for a 2400+ and see how that works, or I may just go with the ABIT recommended 2100+. I was originally running a 1600+.

Well, I exchanged my 2500+ Barton for a 2400+ Thoroughbred. Installed, cleared the CMOS and booted, but it did not detect correctly. Went into the BIOS and set the speed to 2200+ (highest it would go) and when it booted it showed as a 2400+! Now I'm wondering if I could have gone as high as a 2600+ Thoroughbred.

he,

you choose the easiest way..

anyhow, you could run your +2500 barton
at real 2,4 ghz and have 512 kb cache..
