Rebuilding My Chia Farming Rig

The goal I wanted to accomplish with this rebuild, was to reduce the number of computers farming Chia. While retaining the hard drive being used. Doing so will reduce energy consumed and the space taken in my workroom.

Rebuilding The Farmer

My old farmer computer was a big old workstation and quite the power-hungry beast too. Plus the darn thing didn’t have much for installing extra storage. I wanted something smaller and have much more storage capacity.

With that in mind, I went with a Fractal Design Node 804, not only was it small but had eight 3.5″ drive slots.  I went with a GIGABYTE B450M DS3H Motherboard, it had 4 slots for ram, m.2 slots, and two PCIe 16 slots. The latter being important since I need them for installing the drive controllers.

I installed an AMD Ryzen 3200g APU with 16Gb of Memory. Not much CPU performance is needed for Chia Farming so an APU is more than good enough for the task. The Power supply I used was a 1000w EVGA SuperNOVA this should help a lot for supporting more drives. But it will also improve power efficiency. The drive controllers are Dell Perc H310, both of which were flash to the IT firmware.

During this rebuild, I took all my largest size drives from my Harvesters and place them in my new farmer. This meant that there were thirteen 8TB drives and two 10TB for a total of 114TB of Drive space.

Harvester Rebuild

I decommission one Harvester since I manage to fit all the drives to one machine. The great thing about this Harvester is it’s better equip than the farmer. it has a better motherboard, CPU, and more ram. I attach all the SSD’s I use for making plots onto this Harvester. So the farmer can be focused on testing challenges than making plots. Improving my chances of getting a block reward.

My Chia Farming Setup

With this rebuild, I manage to reduce my power consumption by at least half and got it down to two computers. Plus I can finally have my main computer back, after using it to help speed up my Chia plotting. I do want to replace the Harvester case, with the same one from my Farmer. But I already over-extended my spending on this project. If interest in Chia happens again, I might expand. until then I’ll let it continue what I got now.
