Wire Trick

I have read about the 'Wire Trick' but have been unable to find a tutorial on how to do it. I have a Biostar M7NCD motherboard (not pro) and wish to increase the voltage to my CPU (it is currently 1.65v) to see what I can overclock it to. Can anyone point me in the right direction or even better tell me exactly what to do please.



AMD Athlon XP, 1917 MHz (11.5 x 167) 2600+ Barton
Biostar M7NCD
nVIDIA GeForce FX 5200
Maxtor 10 300gb
Sony DRU-810A DVD-RW
2x 512mb PC3200 (200 MHz) DDR SDRAM
 
in order to change the voltage you have to go into the BIOS, but like mrjack said you should't have to up the voltage just yet.
 
Some Athlon XP's are known not to be very "overclocker friendly", and some of them need significant voltage increases in order to see a fairly good overclock. However you should be able to raise the voltage in your BIOS, and you shouldnt have to manually tweak the board in order to raise it.
 
I got my 1800+ ([email protected]) up to an Athlon XP 2500+ ([email protected]), 2562+ to be exact. :P And all that without raising the Vcore at all.

The 2562+ was calculated using the following formula:

1500+(2041-1333)x1.5=2562

The nearest ratings to that used are 2500+ and 2600+, but it's "rounded" downwards.

A little bit of regedit and voila! The AMD Athlon XP 2562+ :P

EDIT:

And here's a "p-rating" calculator for AMD Athlon XP's.
And the pin-mod guide.

I cant change the voltage in the Bios for this motherboard (M7NCD). I increased the FSB to 180 which gave me 2080mhz but it kept crashing. Its running at 170fsb giving me 1955mhz at the mo and is ok. Will try to bump it up a little. Maybe i need a better heatsink and fan before i carry on??? Would still like to know how to do the wire trick.

That depends on te current temperatures. Either go into BIOS or download SpeedFan/Everest and tell us what your CPU temp is. If it's already on the low side, than a new heatsink/fan wouldnt make much of a difference.
 
You should try raising the FSB 2-3MHz and boot up and see if you get any crashes. My comp could boot up with the FSB at 180 but it wasn't stable, 185 it wouldn't boot at all. Found that 177MHz was the stable point.
 
I've up'd the FSB to 177 and the processor is running at 2037mhz at around 40 degress celcius and it seems to be running ok. Played Quake 4 for about 10 mins and the processor went up to 44 degrees but i know that is still fine. Well i've got 220mhz more out of it. Thanks for all you advice everyone.
 
Your CPU is now the equivalent of an AMD Athlon XP 2800+, Barton core.

Using a program called uAMDtool you can calculate the rating of Morgan, Palomino/Thoroughbred, Barton and AMD64 CPU's. And you can change the FSB and multiplier. Quite handy, and according to this my CPU is a 2600+ Thoroughbred. :P
