GIGABYTE MS03-CE0 Server Motherboard ATX LGA 4677 Intel C741 8x DDR5 RDIMM 7x PCIe Gen5 AST2600 BMC

Two things in the box will catch you out, so plan for them. First, no CPU heatsink is included — the retail box contains the board, an I/O shield, a quick start guide and three CPU carriers, but the socket-E cooler is a separate purchase and the carrier type has to match it. Second, only one SlimSAS 4i to 4 x SATA cable is supplied despite there being three SlimSAS connectors. If you need more than four SATA devices, order two more cables. Note also that there are no 7-pin SATA ports at all on this board — all twelve SATA channels are reached through SlimSAS breakout cables.

Check your power supply before ordering. The board uses a standard 24-pin ATX connector plus two 8-pin ATX 12V connectors. It needs no proprietary PSU and fits a standard ATX chassis, but many desktop supplies provide only one EPS 8-pin lead, which is not enough for a 350 W processor. GIGABYTE publishes no PSU wattage requirement for the board itself.

Revision matters on this part. GIGABYTE publishes the MS03-CE0 under a combined rev. 1.x / 3.x page with a shared specification table and no per-revision differential of any kind. The full retail part number carries a revision suffix — a trailing -1 or -3 — which the base code alone does not pin down. If 5th Gen Emerald Rapids support is essential to your build, ask your supplier to confirm the revision suffix in writing and check the shipped BIOS version rather than assuming.

Finally, know the limits. Networking is 1 GbE only — two Intel I210-AT ports plus a dedicated management port. There is no OCP 3.0 slot, so all network expansion goes through the PCIe slots. The single M.2 is PCIe Gen3 x4 from the PCH, not Gen4 or Gen5, so a modern NVMe drive will be throttled there. TPM is a header, not an onboard chip, and requires the optional CTM010 module. The VROC connector is present but the VROC key is not included.

✓ Single-socket Xeon servers, storage nodes and build hosts needing many full-length expansion cards

✓ GPU, accelerator or NIC-dense builds — seven PCIe Gen5 x16 slots, all CPU-attached

✓ Memory-bandwidth-sensitive workloads using all eight DDR5 channels

✓ Custom server builds in standard ATX chassis with standard ATX power supplies

✓ Deployments needing out-of-band management with HTML5 KVM on a dedicated LAN port

The MS03-CE0 exists to solve one problem well: getting a lot of CPU-attached PCIe onto a single-socket board that fits an ordinary ATX chassis. Seven slots, all physically x16, all wired to the processor rather than through the chipset, is more direct expansion than most single-socket platforms offer at this size. If you are building a GPU box, an inference node, a capture or NIC-dense appliance, or a storage head with several HBAs, that is the specification that matters and it is the reason to look here rather than at a workstation board.

The rest of the platform is sensible rather than exciting, which for a server board is a compliment. Eight DDR5 channels on one socket, up to 5600 MT/s with a 5th Gen part. Twelve SATA channels routed through SlimSAS so the board stays tidy. An AST2600 with a dedicated management port and HTML5 KVM, which means you can rebuild the machine from a browser without a crash cart and without buying a licence key — GIGABYTE lists no separate licence for KVM or media redirection, which is not something every vendor can say. And because it takes standard 24-pin ATX plus two EPS leads, it is not locked to a GIGABYTE barebone.

Where you need to be careful is what is not in the box and what is not in the spec. No heatsink — three CPU carriers, yes, but the socket-E cooler is yours to source, and it has to match the carrier. One SATA breakout cable for three SlimSAS connectors, so a twelve-drive build starts with a shopping list. Only one GBe networking, no OCP slot, and an M.2 that is Gen3 x4 off the chipset rather than anything faster. None of those are faults exactly — they are choices that put the silicon budget into the seven Gen5 slots — but they will each surprise someone who assumed otherwise.

The one genuine risk on this part number is revision. GIGABYTE publishes the MS03-CE0 under a single page titled rev. 1.x / 3.x, with one shared specification table and no statement anywhere of what differs between them. The full retail SKU carries a suffix identifying the revision; the base part number does not. The circumstantial evidence — older datasheets and listings naming 4th Gen only, current ones naming 5th and 4th — points to rev 3.x being the Emerald Rapids-capable board, but GIGABYTE does not say so, so we will not state it as fact either. If your processor is 5th Gen, treat the revision as a purchase condition and get it confirmed in writing.

Two last things worth knowing. The operating temperature ceiling is 40 degrees Celsius, which is worth a thought in a Cyprus server room in August rather than a detail to skim past. And the warranty is three years under GIGABYTE's enterprise terms, not the one year that at least one reseller advertises against this part — enterprise hardware is covered by a different policy from consumer boards, and it is worth knowing which one applies to you.
