Help, Sempron 2800+

I know that there are many topics about it in various forums on the net so on ... and I know that I will dig something old and beaten, but very confusing (at least for me)

OK, enough of introduction and I come to the point.
The following is the case, I have the old-vm a7n266 jumper with the mod, with cooler of the K6-2 chip and liabilities in MOSFETs, turning a perfectly sempron 2800+ (181 x 12.0 = 2172 MHz). The bid is that the multiplier is locked at 12x, does not change or charge with nature.
I get this multiplier for 14x. It seems to me, this is locked sempron.

If I connect the bridge L5 will release the multiplier? In theory it becomes mobile, and can change by software, but on software works with the nForce chipset a7n? Or do I change the bios?

I bridge with graphite if they can not just delete and back as before... but I want ideas and suggestions, if possible reports of experiences with this mobo / proc.

Anyway, thank you for any comments that arise this topic.

I had a plate of these .... Very good! Nor did the MOD, and used with an Athlon 2800+. It was a A7N266-VM @ A7N333-VM.

About MOD in processor, I never did. The sought in a (long) topic of the panel. Certainly there's people who has already made all possible experience with this card.

I made the mod of the bridge in my L5+ Semprom 2300. It works very well until it begins to recognize as mobile hour but time does not. If you can close the bridge with anything other than with graphite, after a while you have to remove the processor and redo the mod. I quit after having to disassemble it off all the mod 2x in a week, also was not far ahead ... 2100Mhz@1.675 (with the mod) against 1900Mhz@1.5v is a good difference.
