Built when Netflix first took away password sharing. Thanks for the heads up Netflix! Would not want to start this project now 😂
Edit: adding temp and specs
I9 11900k Z590I Vision D ITX mobo 64gb memory The 16x lane is bifurcated to run: Intel a310 & Lsi 9305 16e into a hp dl380
Drives are 10x 14 tb wdd in raidz1, 6 256gb sata ssds in a pair of 3 wide mirrors for special vdev metadata, a 512gb nvme for read cache, and a 64gb optane for slog
If I’m not mistake only hobbyist level motherboards let you control the voltages and if one knows enough to get one of those they probably don’t need the advice I gave.
Also it’s hard to end up with a non-working or unstable configuration with underclocking, whilst it’s pretty easy to do so with undervoltage.
That said, for those who know what they’re doing, your suggestion definitely delivers lowers temperatures than underclocking alone though at the risk of a less stable system (which can be ameliorated with proper stress testing).
