So, as it turns out, the replacement mobo I bought was completely dead when I got it home. Thought there was something wrong with the MCP2221a so I loaded up a processor and ram..... nothing.

The shop I bought from is pretty reputable and said they tested the board before pulling it. No way it was dead. Took it back down and they couldn't get it to start either.

They bench tested another unit in front of me and off I went.

All vrm programming went smooth. Bios and firmware updated. Ready to swap back in and finish this thing.

On a side note, they asked what processors I was using. They asked if I would like to see the heatsinks that went with them.

Apparently they aren't a standard part number

Well, if it wasn't for bad luck.....

1st board = JUNK

2nd board = DEAD

3rd board = PERFECT

Loaded firmware (check)
updated bios (check)
unlocked VRM (check)
hours of component swap (check)

except....

The 2020 board has bigger capacitors and when you remove the blue cpu clips, sometimes they are in the way

I actually have parts motherboards with what I believe are those same capacitors if you need some spares, I did also chase down the part at Mouser or something but who knows if I can find that information.

found these on the junk board I just removed. If I can fake my way through with the hot air solder unit, I might make it.

THANK YOU FOR YOUR SUPPORT.

I have no idea what I'm doing with the hot air soldering station and still managed to remove a few intact, it must not be too hard.

Had to remove a switch on the front control panel and it was more stubborn than I thought. I am more worried about getting it back on. As a surface mount component, you have to presolder the pads, heat up and flow them without destroying all the components around it. No experience with that. I'm about to get some though.

Luckily I bought all the correct rosins for the job previously.

No one is going to be able to say I didn't work for this build

So, I think I fixed the capacitor. I couldn't get it to lie down flush to the board, but I am pretty sure I got it connected.

So I assembled everything and primed the water loop.

Started the machine and everything came on. I forgot to put the fan spoofers on. Then I see water leaking out the back lower part of the motherboard. I jump to the front and can't see any leaks. I then see what looks like water pouring over the lower ram. I immediately pull the power.

I look at the ram, but it appears to be dry. I can't find any evidence of a leak at any joint. Below the ram there is a little puddle of liquid here

There is no continued leak. I try to plug the machine back in and the frosted plastic loop by the plug is flashing orange.

Still not any evidence of a leak anywhere.

So before bed last night I decided to pull the ram, to see if I was hallucinating about coolant pouring over the ram.

All ram sticks below the top water block wet. Going to spray them down with alcohol and blow them out with the compressor

I have to pull the lower water block, don't I??

orange light comes also if bad RAM. check error LOGs
nothing mentioning ram, but I pulled the plug the second i saw the water pour over the ram.

That was yesterday. I have since cleaned all the slots and ram with alcohol and blown them out. I also removed and sprayed under lower cpu

I think the psu error is a leftover from when I tried to restart the system yesterday with the ram wet.
