ECC and DDR5 2 days ago

So as I was overclocking my AMD Ryzen 7 2700 I discovered that the Infinity Fabric has ECC because if I tried to run my fancy DDR-3466 ram at full speed I started getting logged errors from it. Those failed transactions slow down the system because the data needs to be corrected or even re-sent. The RAM runs fine overclocked at DDR4-4200 in a newer system, but my old Ryzen 7 2700 couldn't handle anything past DDR4-3266 without the errors creeping in.

Without the reported ECC on Infinity Fabric I would have had no idea that the errors were happening and affecting performance.

But they didn't. The deal to buy 40% of the world's memory never happened after the price increases the news generated.

I run my Pihole on the first Pi... the 256mb version.

  dietpi@solo:~$ free -m
               total        used        free      shared  buff/cache   available
  Mem:             223          54          18          11         170         169
  Swap:            767          10         757
I also have a RPi3 with Pihole, Unbound, and Tailscale... for Tailscale:
  dietpi@cubano:~$ free -m
               total        used        free      shared  buff/cache   available
  Mem:             956         233         473          24         289         722
  Swap:           1088           0        1088
Still plenty of space in 1GB of ram, and OpenWRT is probably a bit more compact than DietPi.
