1.4 Jumpers and Connectors
Connectors on the AIMB-287 motherboard link it to devices such as hard disk drives
and a keyboard. In addition, the board has a number of jumpers used to configure
the system for your application.
The tables below list the function of each of the board jumpers and connectors. Later
sections in this chapter give instructions on setting jumpers. Chapter 2 gives instruc-
tions for connecting external devices to your motherboard.

1.7 Safety Precautions
1.8 Jumper Settings
This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboard’s default settings and your options for
each jumper.
1.8.1 How to Set Jumpers
You can configure your motherboard to match the needs of your application by set-
ting the jumpers. A jumper is a metal bridge that closes an electrical circuit. It consists
of two metal pins and a small metal clip (often protected by a plastic cover) that slides
over the pins to connect them. To “close” (or turn ON) a jumper, you connect the pins
with the clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-
ting jumpers.
Warning! Always completely disconnect the power cord from chassis whenever
you work with the hardware. Do not make connections while the power
is on. Sensitive electronic components can be damaged by sudden
power surges. Only experienced electronics personnel should open the
PC chassis.
Caution! Always ground yourself to remove any static charge before touching the
motherboard. Modern electronic devices are very sensitive to electro-
static discharges. As a safety precaution, use a grounding wrist strap at
all times. Place all electronic components on a static-dissipative surface
or in a static-shielded bag when they are not in the chassis.
Caution! The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if battery is incorrectly replaced. Replace
only with same or equivalent type recommended by the manufacturer.
Discard used batteries according to manufacturer's instructions.
Caution! There is a 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.

1.8.2 CMOS Clear (JCMOS1)
The AIMB-287 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few
seconds, and then move the jumper back to 1-2 closed. This procedure will reset the
CMOS to its default setting.

AIMB-287 User Manual 10
1.9 System Memory
AIMB-287 has two sockets for a 260-pin DDR4 SO-DIMM. These sockets use a 1.2 V
unbuffered double data rate synchronous DRAM (DDR SDRAM). DRAM is available
in capacities of 4GB, 8GB, 16GB and 32GB. The sockets can take any combination
with SODIMMs of any size, giving a total memory size between 4GB, 8GB, 16GB,
and up to max 64GB. AIMB-287 does NOT support error checking and correction
(ECC).
1.10 Memory Installation Procedures
To install SODIMMs, first make sure the two handles of the SODIMM socket are in
the “open” position, i.e., the handles lean outward. Slowly slide the SODIMM module
along the plastic guides on both ends of the socket. Then firmly but gently (avoid
pushing down too hard) press the SODIMM module well down into the socket, until
you hear a click when the two handles have automatically locked the memory module
into the correct position of the SODIMM socket. To remove the memory module, just
push both handles outward, and the memory module will be ejected by the mecha-
nism.
1.11 Cache Memory
The AIMB-287 supports a CPU with one of the following built-in full speed last level
caches:
20MB for Inter Core i9-10900E/i9-10900TE
16MB for Inter Core i7-10700E/i7-10700TE
12MB for Inter Core i5-10500E/i7-10500TE
6MB for Inter Core i3-10100E/i7-10100TE
6MB for Inter Core i3-10100E/i7-10100TE
4MB Pentium G6400E/G6400TE
2MB Celeron G5900E/G5900TE
The built-in second-level cache in the processor yields much higher performance
than conventional external cache memories.
1.12 Processor Installation
The AIMB-287 is designed to supported Intel 10th Gen LGA1200, Core i9/Core i7/
Core i5/Core i3, Pentium, Celeron processor.
