    Well. The RAM survived. Two of the Three GPU's survived (RIP).

    I purchased a 2950x as a replacement CPU. Which has been pretty impressive so far for multiboxing.

    The motherboard and CPU came in Apple-esque packaging. Nicely presented, plenty of extra goodies to make you feel like you are opening something amazing. Impressed with the build quality of the motherboard to be honest. Really impressed.

    This whole rebuild took a stupidly long time (17 working hours) due to the weird way it detects/populates the sockets.
    The official documentation on how to use the 'Bios' USB slot quotes from the x99 series which is completely different. For example in the past you couldn't have the CPU/RAM installed in order for the 'BIOS' USB slot to work. With the x399 you NEED it all populated for it to work.
    Also requires a USB 2.0 drive which I didn't see... had to go through about 30 USB drives before I found an old one hah.
    Only had to mess around with it as the Threadripper 2s aren't detected on older bios-- at least they have this autoflash feature. Would suck to have to buy an older CPU in order to get it to post, flashing the old way.

    Had all the RAM slots filled... aaaannnnddd it kept throwing error codes at me. I would take the RAM out, re-seat it, it would work, then stop working. By working I mean it wouldn't be detected in the BIOS. I then found out about the weird quirks.. on the first post it would notice 2 sticks, next post it would notice 4.. until it was all detected. Weird AF.

    Motherboard kept giving GPU error codes. I had to drain the loop and install the cards ONE AT A TIME for it to post. Install one card, boot it up, let the bios see ONE CARD.. save and exit. Install a second, into bios, rinse repeat until all Three were seen by the motherboard. However when I got into Windows only two are recognised (siigh).

    All in all not so bad.

    --overclocking tomorrow! I'm hoping for at least 4.4ghz on all cores.

    Ok so overclocking on this chipset is a little different. Here are some results with Cinebench to show what I mean.
    I metered the mboard tracks and my PSU output.. it was able to push through a stupid amount of power to the CPU. The Ryzen Master program tells me the chip can take 700w... How batshit crazy is that.

    So far I have found that I can OC to 4.5ghz and it's benchmark stable.. however the results are terrible. I then noticed when leaving it at stock and having the Auto-boost (Precision Boost Overdrive) manage everything, it was able to beat my Manual OC (4ghz) with it's boosted frequency of 3.85ghz (Cinebench shows it at 3.50). Poked around to find out why and it turns out this particular chip wants LESS voltage. So dialed back up the 4.1ghz and lowered the Vcore/Vcore SOC and it benched a lot higher. I did think it wasn't getting enough voltage and it was throttling originally-- which is why I metered the connections to double check.

    It continues!

    Another example of the weird Voltage thing with the CPU.
    Someone else who OC'd to 4.1ghz was achieving 3628 cinebench scores consistently. Trying to find out what his voltages were like.
