Questions about this item

Does the Xeon E3-1545M v5 throttle at 3.80GHz under sustained load?

The processor runs at 2.90GHz base and can reach 3.80GHz Max Turbo; actual sustained speed depends on the laptop cooling solution.

How hot or loud does the CAP00 LA-E311P board get during all-day operation?

The motherboard itself has no fans; thermal output and noise come from the Precision 7520 chassis cooling design.

Which memory modules must I already own to populate the four slots?

You need DDR4 SDRAM sticks rated for 2400MHz or 2667MHz, up to 32GB at 2667MHz or 64GB at 2400MHz total.
