It's 4+1, would be fine for Phenom II x4 or FX-6300 overclocking. Not sure about FX-8300 chips though.

Sabertooth 990FX R2.0, Crosshair V Formula-Z, AsRock Fatal1ty 990FX, & Gigabyte 990FXA-UD5 or UD7.

 

If you want a budget board then Gigabyte 990FXA-UD3 or Bioware TA990FXE. Both boards can overclock as well as the other guys; but they do not have as many features.

The sturdy FET's mentioned for the DFI 790FX board (AOD472) are rated for 25w at 100c. Same VRM config is good for 200w @ 100c.
Just goes to show how much impact quality components can have on a boards power output characteristics.

Interesting!

From: http://www.datasheetcatalog.org/datasheets2/17/171458_1.pdf
Their Rds of 5.6 mOhm is only a little better than the dreaded NIKOS P0630s found on the notorious 870A-G54 and other MSI wonders. rolleyes.gif They may well be built better, however, and thus be more resistant to degradation and eventual thermal runaway / meltdown. (I suspect some of the NIKOS destruction is due to the simple fact that the transistors are not meeting their stated specs.)

At any rate, TO252 mosfets with Rds values as low as 2 mOhm are out there. They are a bit more expensive and, having a physically larger junction, would likely require more robust (= $) mosfet drivers. That said, even the top-of-the-line hardware costs only a few tens of cents more than the cheaper stuff. For a few bucks, the motherboard manufacturers could install mosfets with ~3x the power capacity. mad.gif

Yea.
Besides, even with additional heatsinks strapped on top, the vast majority of the heat will go through the soldered base, into the motherboard. Cool the motherboard and you cool the MOSFET, as well as all the other VRM components that get hot. Heatsinks won't hurt, unless they block airflow to the board, but IMO they may not help that much either. AFAIK, the black mosfet body is made of some manner of plastic or epoxy, depending on the mfg. Unless special compounds are used, this sort of material has a rather low thermal conductivity and, since the actual junction is buried several mm of this plastic, the heat has a hard time making it to the surface. The junction IS attached directly to the metal tab on the bottom that gets soldered to the motherboard, so thermal resistance along that path is quite low.

Has anyone tried to upgrade their MOSFETs to better ones on-board? I know EVGA made an external upgrade, but I'm talking about direct replacement. Would such an attempt even work, or are there failsafes inplace that would prevent it from working?

Just curious for sake of discussion, not looking to make such an attempt.

I'm somewhat determined to give it a try. Digikey has a wide list of Infineon MOSFETS to pick from (almost too many!) I haven't looked at all, but have found one with 2x better Rds resistance and similar gate charge values. http://www.infineon.com/dgdl/IPD031N03L_rev2.1.pdf These will literally produce half or less the heat of the NIKOS crap that's on the board now.

It's really hard to do, especially with consumer grade soldering equipment.

True, a Rat Shack slaughtering iron won't do more than narf the board.

Looking at photos of a whole bunch of different brand and model motherboards, it would be a tight soldering job, but, anyone who is experienced with soldering could do it. If I had a motherboard to sacrifice, I would absolutely try; I've been using a soldering iron since I was 13.

But yeah, a Radio Shack soldering iron wouldn't be the tool to get the job done, that's for sure.

people have replaced mosfets (i think), but like has been said, it would be a super tight solder job.
