Product Warranty (2 years)
Advantech warrants the original purchaser that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that have
been subject to misuse, abuse, accident, or improper installation. Advantech
assumes no liability under the terms of this warranty as a consequence of such
events.
Because of Advantech’s high quality-control standards and rigorous testing, most
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product is defective, follow the steps outlined below.
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages displayed when the prob-
lem occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain a return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

Declaration of Conformity
FCC Class B
This equipment has been tested and found to comply with the limits for a Class B dig-
ital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. However, there is no guarantee that interfer-
ence will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to a power outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for assistance.
Caution! There is danger of a new battery exploding if it is incorrectly installed. Do
not attempt to recharge, force open, or heat the battery. Replace the
battery only with the same or equivalent type recommended by the man-
ufacturer. Discard used batteries according to the manufacturer's
instructions.

ASMB-830 User Manual 2
1.1 Introduction
The ASMB-830 server board is the most advanced AMD EPYC 7002/7003 Proces-
sor family board for server-grade IPC applications that require high-performance
computing power and multi-expansion slots. This server board supports DDR4 ECC-
REG 3200 MHz memory up to 2048 GB. ASMB-830 is equipped with PCIe 4.0 and
provides five PCIe x16 slots and two PCIe x8 slots. In addition, the ASMB-830T2
SKU has dual Gigabit and dual 10GbE Ethernet LAN ports that eliminate network
bottlenecks.
One dedicated GbE LAN RJ-45 can be shared with the IPMI function to allow remote-
control management. With AST-2500 BMC, high reliability and outstanding perfor-
mance make ASMB-830 the ideal platform for industrial server/networking applica-
tions.
By using EPYC processors, ASMB-830 offers a variety of features such as 5 x USB
3.2 Gen1 connectivity, 2 x Mini-SAS HD (support 8 x SATA III), 1 x SATA III, and 2 x
M.2 NVMe (PCIe 4.0) interface. AMD Infinity Guard helps decrease potential attack
surfaces as software boots, executes, and it keeps your data protected as it is being
processed.
Powered by an EPYC processor, the single-socket ASMB-830 server board delivers
compute power that is capable of handling large workloads so that you can satisfy
your business requirements without having to scale up to dual-socket servers— thus
helping minimize licensing costs and reduce power consumption.
1.2 Features
1.2.1 General
AMD EPYC 7002/7003 Series Processor support: ASMB-830 is equipped
with a single CPU socket to support AMD EPYC 7002/7003 Series processors
from 8 to 64 cores (or 16 to 128 threads per socket).
High performance I/O capability: 2 x 10GbE + 2 x GbE LAN, 5 x PCIe 4.0 x16
slots (x16 link) + 2 x PCIe 4.0 x8 slots (x8 link), 9 x SATA (incl. 8 via Mini-SAS
HD), and 2 x M.2 NVMe 2280/22110, 5 x USB 3.2 Gen1 (incl. 1 x Type-A) ports.
Standard ATX form factor with industrial features: ASMB-830 provides
industrial features like a long product lifecycle, reliable operation under a wide
temperature range, watchdog timer, etc.
IPMI 2.0 support: ASMB-830 (T2 and I SKUs) is equipped with an ASPEED
2500 BMC chip and supports IPMI 2.0 (Intelligent Platform Management Inter-
face 2.0) via a dedicated LAN and a shared LAN port.
KVM over IP: KVM over IP allows BIOS level remote control of ASMB-830 (T2
and I SKUs) through your own computer.
Note! 1. The IPMI module will be included in ASMB-830I and ASMB-830T2
SKUs. Only the ASMB-830T2 SKU can support 10GbE LAN ports.
2. Please refer to the ordering information at the front for IPMI and LAN
support for individual product SKUs.

1.7 Installation of Memory Modules
Memory performance is affected by different DIMM configurations. To reach optimal
memory interleaving, be sure to install identical DIMM types with the same size,
speed, and number of ranks on those memory slots corresponding to the correct pro-
cessor.
The following table indicates recommended DIMM configurations with a single EPYC
processor. Based on the guideline, you may adjust your memory configuration
according to your PCIe expansion card configuration.
The motherboard will support odd-numbered modules (1 or 3 modules installed) but
is unable to activate Dual Channel Technology. For great performance, a balanced
memory population is recommended.

Note! 3, 5, 7 DIMMs are not recommended DIMM populations.

1.8 Processor Installation
The ASMB-830 is designed for AMD EPYC 7002/7003 Series processors.
1. Unscrew the three screws (shown above in red circles) on the top of the socket
retention mechanism (SRM), then rotate the Retention Frame and Rail Frame
(with external cap).
2. Remove the external cap by pulling upwards.
3. Install the carrier frame/CPU package to the rail frame, then remove the PnP
cover cap. Be very careful not to drop the PnP cover cap into the exposed con-
tact field during the removal process.
