Question about motherboard TDP with 95w CPU

Currently I have a Biostar A770e3 I bought a long time ago that was rated as 95w. However, as you can see here:

http://www.tigerdirect.com/applications/SearchTools/ite... (second to last review)
http://www.biostar.com.tw/app/en/mb/introduction.php?S_... (supports 125w cpu's)
http://www.tomshardware.com/forum/299574-30-help-biosta...

The motherboard now supports 125w cpu's with absolutely no change to the model, only a BIOS update!

I would like to overclock a AMD Phenom x945 3.0 GHZ to maybe 3.6 or so Ghz. I am wondering if the BIOS update would actually increase the safety of overclocking a 95w CPU, or does it simply allow the motherboard to accept 125W CPU's?

In other words, Is this motherboard safe to run a overclocked 95W (therefore higher than 95W) CPU WITHOUT the BIOS update? Or can a BIOS update magically make a mobo able to handle higher wattage more safely?

I wouldn't want to make a risky BIOS update unless I'm sure that it actually makes a difference

I doubt it, though I guess they might have changed a PWM controller or something. Most likely they just tested the new chips more recently.

I wouldn't do much though; those VRMs look gutless.

I read that if you apply heatsinks to the mosfets it will make it a lot safer to overclock, and practically offset the risk of using 3+1 phase motherboard. True or not?

To some degree, but it's a little hard to do that.

It will reduce the risk, but they're still not going to power that much.

It's a very risky proposition. I'd have to err on the side of caution and avoid it if possible. Can you do it? Probably, as long as Biostar allows it. But if you are intent on doing it, make sure you have a back up plan in case the worst does happen. You'll be pushing 130+ on a rated 95. Good Luck.
