I don’t have any information to contribute currently but I am interested in this topic since I too have one of these boards coming to me.

Here is SD-11 with 8 mosfets: http://hw-museum.cz/mb/61/fic-sd11 no way to read them.
I thinking they revised the boards and the newer w/4 mosfets can handle the current just fine where the ones with 8 needed all 8 because of the parts used could not handle the current/wattage.
Those Fairchilds max at 100Amp, just an observation....
As for power supply issues: same with socket A you need very high 5v amp rail for these to work well from my experience.
Most newer ATX cannot deliver the 5v amps full time as required, something like the Antec True-Power 480 that can give max of 38Amps on the 5v is what I used w/o issue but they are no longer made 🙁

There is actually one for sale on eBay right now, maybe you can the seller what they say.

Yeah, I've already messaged one of them. Hopefully they'll get back to me.

Maybe, but there's another listing for the Compaq version of the SD-11 that includes the OEM PSU: it only had 25 amps on the 5v rail. The complaints about the SD-11 being picky with PSUs seemed to be commonplace when it was released, as well, and that the handful of PSUs approved by FIC had 32 amps and higher on the 5v rail.

Also, I took a quick look at another Athlon Mobo I have (a Soltek Socket a NF2 pseudo ITX unit) and it apparently uses the SMD version of a very similar MOSFET: http://www.farnell.com/datasheets/245431.pdf along with this Infineon MOSFET: https://pdf1.alldatasheet.com/datasheet-pdf/v … IPP06N03LA.html
I'm planning to pick up a multimeter tomorrow so I can tone out which one is the high side and which one is the low side.
I looked into buying some of these Infineon MOSFETs but anyone who sells them has really high minimums, so barring learning what FIC used on the Compaq board, I need to know how close to that Infineon's specs I need to get and what values are most important to match. I did find one that was somewhat similar: https://www.mouser.com/datasheet/2/196/IPP055 … 1.04-522939.pdf

Update: I took a multimeter to my mobo and confirmed that it's the low side mosfets that FIC deleted in the retail SD-11 and that the Fairchild MOSFETs are indeed the high side ones (as they appear to be in my Soltek SoA NF2 motherboard).

So I just heard from one of the people selling a Aspen 2 on Ebay and he confirmed that all 8 MOSFETS are Fairchild FDP7030BLs There are some differences between the 7030L and the 7030BL but I doubt they're enough to be concerned about, so I plan to use the 7030Ls I bought off ebay a few days ago, however, I figure the BLs would be fine as well. It depends on whatever is cheapest and easiest to get. Please note I am a freaking N00B at analyzing this stuff so follow at your own risk! I plan to install all of this stuff once I get some time to recap the larger value caps. FWIW, my "retro" PSU is a Enermax Liberty semi modular unit with a 30 amp 5v rail : I'll update if it posts and enters bios on it before the board goes under the knife. https://www.digikey.com/en/products/compare?s … uCwANAE9YkABfIA

I used to have one of these (Compaq version) but I'm not sure if I kept it when I moved. I looked in some boxes but didn't find it.
Mine never worked, but I found my old notes about it.
The 1000uF cap near the power input was blown. It's connected to +5V so it doesn't really have to be rated any higher than 6.3V.
One of the 8 MOSFETs was missing it's heatsink, and at least that one was a FDP 7030BL, so the same as what the eBay seller told you about their board.

If you need closeup pictures of something then I can put more effort into trying to find mine. It might have been stuffed into a PC case, I was putting lots of boards into those when I packed.
