Questions about this item

How many DDR4 2933 ECC modules are installed and how many slots remain for future upgrades?

Four 16 GB DDR4 2933 ECC registered modules fill four slots; the board supports up to 512 GB total, so additional slots are available for expansion.

What is the sustained turbo ceiling of the Xeon W-2235 before thermal limits engage?

The 6-core Xeon W-2235 has a 3.8 GHz base and 4.6 GHz turbo; sustained all-core speeds depend on the 1000 W 80 Plus Gold supply and mid-tower airflow.

How loud is the 1000 W 80 Plus Gold PSU and GPU fans during an all-day render?

The 1000 W 80 Plus Gold unit runs at 90 % efficiency, reducing waste heat; the Quadro RTX 4000 uses a blower cooler that exhausts heat rearward, keeping internal temperatures lower.
