Until recently i owned this board: https://www.gigabyte.com/Motherboard/GA-8I865G775-G-RH-rev-1x#ov which is a very late implementation of the 865 chipset (no C2D support, but still lga 775). When equipped with 4 gb of ram, would detect ~3.7 gb (3.67..) with a Nvidia videocard and ~3.5 gb (3.4..) …

Be bold, remove all ram and the video card. If anything else is ok then you should have the appropriate beeps present on the pc speaker (if connected correctly).

Best way, for me, if you don't have a tool like this https://www.aliexpress.com/item/32812134008.html, is to use a wear down https://www.amazon.com/Tweezees-Professional-Precision-Stainless-Perfectly/dp/B00PVWRLO0 that is 'adapted' to fit the 'extraction' holes. But other the that, you can use …

Yes, it should work with Solo 1, it has the VT8237 south bridge. Also you can try SBEMU: Sound Blaster emulation on AC97. FM801 should have worked on the other motherboard (with the Intel chipset).

Also on some older psu's there will be a connector to power the speed display(that's the standard/normal way), don't know if that's your case because you posted only pictures of the connectors.

If you have more then one, try swapping the bios chip from a working one (chip swap + cmos reset, then test).

The difference from fx5200 to fx5500 is minimal performance wise, assuming same gpu clock, same memory clock and same bus width for both cards (that can be 'seen' in gpuz). So if the chips are real fx5200 or real fx5500 is kind of irrelevant unless you want to be really technical about it.

Those are 128 bit versions of Fx video cards that usually come with slower clocked memory (e.g. 166 mhz instead of 200 mhz, in your case even slower, 133 mhz in gpuz), but beside the penalty for having a slower memory (which is smaller then having a 64 bit bus) they work fine and they are at least …
