Hi! This is the PC I built 4 months ago to replace my old workstation, I use it as my main rig but I travel with it too :)
CPU: 3900X is undervolted to 1.075V (full-load AVX2)
GPU: GTX 1080 to 1720MHz at 0.875V
RAM: 2x16GB 3200MHz CL16 (I had it for a while at 3600MHz CL16 at 1.45v)
Custom cables: Silver premium wire with gold plated connectors
24pin ATX connector 15cm cable length
8pin EPS connector 25cm cable length
8pin PSU to Low Profile PCIe connector 8-Pin
8pin PSU to Low Profile PCIe connector 6-Pin
6pin PSU to 1xSATA 90 degree 15cm cable length
CPU+Soc is around 104W at peak power GPU 145W at peak power
PS: Photos were taken before adding the 2TB 860QVO :)
Back then when it was released it was the most powerful CPU for the mainstream market, yet today despite having the 3950X on sale still a beast. The only problem I see with Ryzen 3000 series are absurdly high voltages on stock, I mean, I got 3.8GHz at 1.275V when it was at full load on AVX2, the temperatures were a bit too high for the build, so I decided to do undervolting as much as I could, getting 4.025GHz at 1.075V passing the Intel Brun Test at very high over 10 iterations, it was just mental, and the best thing was to see that the CPU package power was little over 100W, less than 80W for the CPU+Sock power, which is amazing.
Cinebench R20 7176pts on multi and 466 on single.
Just for fun I did 4.2GHz at 1.175V fully stable too on Intel Burn Test at 10 iterations, getting 7469pts on Cinebench R20 and 487pts in single core.
