Fold8 Dedicated Linux Folding@Home Rig

[Gorgon]

This is Fold8 a dedicated Folding at home rig.

Chassis: Fractal Design Define C

Power Supply: Corsair HX650

Mainboard: Gigabyte Aorus z370xp SLI

CPU: Intel Pentium G5400

Memory: 2 x 4GB GSkill RipJaws V DDR4-2400 CL16

Storage: AData SX8000 128GB m.2 NVMe SSD

Front Intake Fans: Noctua NF-A14 Redux 1500 PWM, NF-A14 iPPC3000 PWM

Rear Exhaust Fan: Noctua NF-A12 1700 PWM

GPUS: EVGA RTX 2070 Super XC Hybrid; EVGA GTX 1070Ti XC Gaming

OS: Ubuntu 18.0.4.3 LTS Desktop

 

The intake and exhaust fans are connected to separate headers on the motherboard and are all controlled by the PCIex16 Thermistor sensor using the Gigabyte SmartFan5 in the BIOS.

 

These GPUs produce on average 1.5M and 730kPPD respectively on Folding@Home, one thread on the CPU is reserved for each video card and the remaining threads are running World Community Grid on BOINC.

 

The RTX 2070 Super consumes an average of about 191 and the GTX 1070Ti 137W Folding with stock fan control and a +65MHz and +150 Shader Clock offsets and Power Limits set to 240 and 217W respectively.

 

The load at the UPS averages out to 450W so with 326W used by the GPUs the CPU and system overhead and Power Supply inefficiency is 124W.
