Description

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 :)

Hardware settings:

  • 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 :)

CPU

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.

Quite a lot of power packed into a small build! Great photos too.

Very clean sff build! Was it hard, and how long did it take you?

Thanks! Well... the Dan A4 is a nightmare to build in if you plan to put and SFX with stock cables and the Asetek 645LT (with a fan grill, is a must if you want to keep away the cables from the fan blades), but once I received the custom thin cables it was waay easier, probably it takes about 1 and a half to 2 hours long to build everything, the worse part is cable management, is quite tricky to get them where you want because there is almost no space, everything else is not that difficult.

I had a bit of trouble mounting the GPU as at the beginning it touched the radiator's 90º fittings, so I needed to move the radiator as much as possible to the front of the case, finally, I got a 1-2mm clearance between both, just enough.

Oh ok, that’s not too bad, but you did do a really good job!
