Micro ATX server board
The ASRock Rack E3C242D4U is a Micro ATX motherboard built around the Intel C242 chipset for LGA 1151 Xeon E-2100 and E-2200 processors. It targets system integrators and small-business IT staff who need a compact platform with IPMI 2.0 remote management and dual Intel I210 gigabit LAN. The board fits 9.6 by 9.6 inch chassis and supports up to 64 GB of DDR4 ECC or non-ECC UDIMM across four 288-pin slots.
IPMI and expansion layout
Integrated IPMI 2.0 with KVM and a dedicated RTL8211E LAN port lets administrators control the server remotely even when the OS is down. Six SATA3 6 Gb/s ports from the C242 handle storage, while SATA0 doubles as a SATA DOM connector and shares bandwidth with an M.2 PCIe 3.0 x2 interface. Three PCIe 3.0 slots — x16, x8 and x4 — provide room for add-in cards, though the x16 slot drops to x8 when the x8 slot is populated.
Installation notes
The Micro ATX form factor uses standard mounting holes, so the board drops into any compatible case without adapters. Builders must populate memory in matched pairs to enable dual-channel operation and should verify that the chosen Xeon cooler clears the DIMM slots and the Aspeed AST2500 BMC heatsink. The shared SATA0 and M.2 lane means only one of those devices can be active at a time, a detail that sometimes catches first-time installers off guard.

שאלות על הפריט הזה
When will the IPMI 2.0 firmware on the E3C242D4U need updating?
The integrated IPMI 2.0 with KVM and dedicated RTL8211E LAN receives firmware updates from ASRock Rack; apply them when new security advisories or feature releases are published.
Which PCIe slot loses bandwidth first when both the x16 and x8 slots are populated?
Slot 6 (Gen3 x16) automatically switches to an x8 link as soon as Slot 4 (Gen3 x8) is occupied, so the x16 slot is the first to reduce throughput.
How loud and hot does the Aspeed AST2500 BMC run during continuous 24/7 operation?
The Aspeed AST2500 management controller draws minimal power and is passively cooled, so it adds negligible noise or heat even under sustained load.
