AMD Ryzen OpenBSD desktop build

So early last month (Aug 2018), I put out a request on Twitter/Mastodon to help replace my now aging AMD Bulldozer (FX-4100) desktop. The response was nothing short of overwhelming, with the CPU and motherboard quickly being snatched from my Amazon.ca wishlist:

  • CPU: AMD Ryzen 2 2700X - 8c/16t @ 3.7GHz
  • Motherboard: ASUS PRIME X470-PRO AM4

The rest followed shortly, including:

  • PSU: EVGA 500W (Model: 100-W1-0500-KR)
  • Storage: Samsung 860 EVO SSD - 500G
  • Graphics card: ASUS ATI Radeon HD6450; identifies as HD7450 (Northern Islands: i.e: "pre-GCN" was selected for radeondrm compatibility)

I was originally planning on scavenging parts from my other AMD desktop, but I wanted to keep it around for testing changes on a broader set of AMD families, so I attempted to find an ATX Mid-Tower case locally, ultimately this didn't pan out...

In the end, it was one of the few parts I ended up ordering for myself, largely thanks to generous donations on PayPal:

  • ATX Mid-Tower case: Corsair Carbide Series 100R Silent Edition (CC-9011077-WW)
  • RAM: Patriot Viper Elite DDR4 8GB (2 x 4GB) @ 2400MHz (Model: PVE48G240C5KRD)
  • Network: Dual-port Intel 82576 GigE adapter (Salvaged part)

The case isn't too bad, it was difficult to get the motherboard mounted properly, but that's probably my fault.. and the PCI-E brackets have some awful screws with poor threading. But I think it's fine overall, feels sturdy and is indeed silent (Bonus: no glass window, or annoying LEDs!)

RAM was the hardest thing to choose from, weighing several different factors including price/capacity and compatibility. From all the reviews online, DDR4 2400MHz is lowest recommended speed for Ryzen, however technically anything above 2133MHz seems to be sanctioned O.C. /w XMP profiles? Very confusing! 8GB is more than adequate for now, but the motherboard has 4 DIMM slots, so I can always upgrade to 16GB with another 2x4G kit in the future.

Thanks to all the people who helped, even with parts recommendations. It was much appreciated! love
