Sata Headers; Oculink Headers; Pcie Gen 4.0 X16 Slot; Ddr5 Udimm Slots - Onlogic Axial AC101 Product Manual

3.3 - SATA Headers

There are four SATA data headers on the Axial AC101 Edge Server motherboard.
The data ports support SATA III 6Gbps storage devices.

3.4 - OCuLink Headers

There are four OCuLink headers on the Axial AC101 Edge Server motherboard that support PCIe 4.0
x4 connections to enable NVMe drives.

3.5 - PCIe Gen 4.0 x16 Slot

The Axial AC101 features one PCIe Gen 4.0 x16 connector on the motherboard which is accessible
by the use of a right angle riser card.
The PCIe riser card edge power draw of the slot is rated to support up to 75W as defined per PCI-SIG.
Support for PCIe adapters up to 150W is supported when using the optional PCIe 6-Pin/8-Pin auxiliary
power header.

3.6 - DDR5 UDIMM Slots

The Axial AC101 supports up to four DDR5 UDIMM slots rated up to 4400MHz.
4400MT/s @ 2DPC-1DIMM
●
4000MT/s @ 2DPC-2DIMM 1R
●
3600MT/s @ 2DPC-2DIMM 2R
●
The system will support both ECC and non-ECC memory with all supported CPU options.

3.6.1 - Supported Memory Modes

The IMC (Integrated Memory Controller) of the processors supports two memory modes,
single-channel and dual-channel. The ability to support the memory modes is dependent upon the
DIMM population.

3.6.1.1 - Single-Channel Mode

In this mode, all memory transactions occur within a single channel. Single-Channel mode is used
when DIMMs are installed in either Channel A or Channel B, but not in both.
3.6.1.2 - Dual-Channel Mode – Intel® Flex Memory Technology Mode
In this mode, memory is divided into a symmetric and asymmetric zone. As per Intel® documentation:
