So ive read that the 780G have problems taking 125W TDP phenom cpus.. so im guess even X2 as well. I recently bought this motherboard and bought my CPU used.. so now, im scared to mount the CPU coz i heard the mosfets get really hot that it might fry my CPU? does that make sense? so i bought like enzotech mosfet heatsinks to help cool it down! any comments about this?
 
Have a look at AT's articles and blog's by Gary key on the 780g. I am pretty sure the Giga board was one of the few that were quite fine with 125w Phenoms but best to do some more research, see what other users have done with the same board.
 
Ummmm - "quite fine" ???

See the review on the new 9950 Phenoms. I think several such boards were melted or otherwise toasted in the process.

I am waiting for the mobo manufax to get honest about this scene and address the issue with a worthy mosfet. I don't hear anything yet. Your heatsinks are a good idea - or just blow it and rma. Do check the cpu support list. And do read the 9950 review.

How do you say product dump?


Keep your receipt.........!

Yes, some boards DID fail but the Giga was one of a few that was fine with 125w Phenoms with proper airflow.

Utilizing our standard test bed components with the 9850BE, we ran our Jetway, ASRock, and Gigabyte boards over 102 hours each with a combination of OCCT, Microsoft Flight Simulator X, and PCMark Vantage benchmark loops. We did this with the case fan modification first and then again with the Thermaltake RubyOrb installed. We did not have any thermal related failures or shutdowns under load as we had experienced with just the retail heatsink installed in previous testing. We also overclocked the 9850BE slightly to 2.7GHz and ran an additional 48-hour combination of OCCT and PCMark Vantage loops without a problem utilizing the two front-mounted case fans and retail heatsink.

Just make sure you have good ventilation.
 
Instal the processor and some sort of active cooling that will affect the MOSFETs (as lopri suggested, a vertical cooler whose fan blows air from above onto the chip and surrounding motherboard could do the job). Do not overclock the chip. Take temperature readings as you increase load on the chip. Only if you feel the temperatures are safe at 100 per cent load, then you might want to play with overclocking.
