Control Computer

Current control computer hardware (1 January 2022):

  • 1x CPU: Intel Core i9-12900K 3.2 GHz 16-Core Processor

  • 1x CPU Cooler: Asus ROG RYUJIN II 360 71.6 CFM Liquid CPU Cooler

  • 1x Motherboard: Asus ROG MAXIMUS Z690 EXTREME EATX LGA1700 Motherboard

  • 1x Memory: G.Skill Trident Z5 32 GB (2 x 16 GB) DDR5-6000 CL36 Memory

  • 2x Storage: Seagate FireCuda 530 2 TB M.2-2280 NVME Solid State Drive

  • 1x Video Card: EVGA GeForce RTX 3080 Ti 12 GB FTW3 ULTRA GAMING LE iCX3 Video Card

  • 1x Power Supply: SeaSonic PRIME Platinum 1300 W 80+ Platinum Certified Fully Modular ATX Power Supply

  • 1x PCIe Serial Card: Rosewill RC-301EU (modified to replace dsub with sma conn)

NOTE Always update the BIOS before installing the computer in the field.

NOTE The motherboard has a 10G and 1G port, an additional network card is not required.

NOTE XMP must be enabled in BIOS to utilize the full 6000 MHz RAM speed. RAM must also be socketed in the optimal configuration DIMM_A2 and DIMM_B2 for two sticks.

NOTE The M.2 drives should be slotted in sockets M.2_2 and M.2_3 as M.2_1 shares PCIe Gen5 lanes with PCIex16(G5)_1 which the GPU is slotted into. The M.2 drives are setup in RAID1 (mirroring) including the operating system. The bootloader on the second drive must be named differently to operate. Should drive failure occur the second bootloader must be pointed to in the BIOS, a new drive can then be installed.

NOTE It is critical during parts selection and installation that the PCIe lanes are dedicated and not split between components. Seamless operation requires the maximization of bandwidth. For the Z690 motherboard this means the GPU is slotted in PCIex16(G5)_1 and the Serial Card is slotted in PCIex1(G3), PCIex18(G5)_2 is not to be filled as it share bandwidth with PCIex16(G5)_1.

NOTE A 1000W+ platinum or greater certified power supply is recommended.

NOTE A 3x120mm (360mm radiator) All-in-one (AIO) liquid cooler heatsink is required. The i9 series CPUs generate considerable heat by default, but the Borealis computer setup will pin each core to its maximum output which will generate even more heat.

NOTE This computer does not require overclocking for seamless operation which will allow for more reliable operation than previous Borealis computer builds.

Minimum requirements:

  • 1x GeForce GTX 2080 Ti with 11GB of GRAM or better

  • 2x 16GB DDR4 (32GB total) 3200 MHz or faster

  • 1x Power supply, 1000W 80 Plus Gold or better

  • 1x Intel Core i9 10 core or better

  • 1x Cpu liquid cooling unit (240mm or 360mm)

  • 1x CPU compatible motherboard with serial port header or an extra unshared bandwidth PCIe slot for a serial card

  • 1x 256GB SSD (operating system partition)

  • 1x 1TB HDD (data partition)

  • 1x Intel X550-T2 10Gb PCIe network card (if the motherboard does not have 10G networking)

NOTE: Intel 82579LM controllers WILL NOT WORK

NOTE A BIOS flash is required to use a RTX3000+ series NVidia GPU.

Networking

  • 3x Netgear XS708E-200NES (North American model #) 10Gb switches (parent model name is XS708Ev2)

  • 1x 5-port network switch that can handle 10Mbps and 100Mbps connection speeds (10BASE-T and 100BASE-T)

  • 27x SSTP CAT 6a 7ft cables or better*

  • 2x SSTP CAT 6a 15ft cables*

Note that the network cables need to be verified for the whole system as not all cables seem to work reliably.

Models tested and known to work include:

  • Cab-CAT6AS-05[GR|BK|GY|RE|WH]

  • Cab-CAT6AS-15GR

Models that were tested and do not work:

  • CAT 5e cables

  • Non SSTP cables (not dual shielded)

  • Cab-Cat7-6BL

  • Cab-Cat7-6WH
