I've copied this post from one I made at DFI/Amdmb, I'm hoping that some of the Vmodding gurus here may be able to determine what I actually managed to do here:

I recently got myself an XP2500-M and it is totally kick-ass! I had it upto 2.7Ghz at 2 volts (well, 2volts DFI fluctuation style) and I still had low temps (<18 degrees) so I was convinced that if I gave it 2.1 volts it would hit 2.8Ghz.

Well this mean't doing the vmod. I decided to do the vmod only (no vsense) because I only plan on going upto 2.1 volts. Well, to cut a long story short, I made a pigs ear of the soldering 1st time round and ended up spending hours bleeding solder away from the 3 IC legs that I'd bridged by using too big a soldering tip (I'm actually quite a good solderer, but my prescision soldering iron is in a box due to me being in the process of moving).

Any way, I powered it back up after cleaning up the mess with the vmod fitted. Nothing

So I removed the Vmod and then noticed that Pin 7 had become unseated from the mother board, my bad. So I re fitted it and powered it up without the vmod. It worked

But, regardless of what I set the bios to, I could only get UPTO 1.85 volts. So I did a little research, I looked at a PDF of the chip (Sadly I do not have the link to hand, can someone provide it please) and found that the IC that DFI have used for the Infinity IS RATED FOR 1.85v operation. So I guessed that DFI have actually vmodded theier own board to get the 2 volts available as standard, because they are using sub spec components. Somehow, with my worst soldering episode ever, I had managed to diable the factory vmod and leave the chip at it's default capabilities.

My only option now was to attempt to fit the vmod again, which I this time managed successfully. I can now go almost as high as I desire. I saw 2.2volts before I got scared and wound it down to 2.1 volts which hovers now between 2.08 and 2.11.

The other thing I now noticed was that I have experienced none of the stabilty issues that guys have come up with for Vmodded DFIs, could it be that by inadvertantly disabling DFIs "mod" to make 2volts possible, I have introduced stability into the system?

I hope that some of the modding gurus can share some light on what I have somehow done. Any ideas?

and was it worth it? Oh yeah!
