Overview
ALEXSOF DDR3 Analyzer card is designed to diagnose motherboard issues by measuring the main voltages in the circuit, displaying POST codes, and analyzing data protocol, configuration lines, read SPD firmware, more.
Instructions for Use
  • Incorrect Connection: If there’s an incorrect connection on any of the lines, “FLOAT” will appear.
  • Voltage Issues: It can check all voltages instantly (SPD, VDD, VTT, RCA, RDQ, RST) If the voltage is incorrect on any line, it will display with a different background color than the other voltages.
  • POST Codes: For motherboards designed with POST code support, the codes will display. For those not designed for this, activity on the SMBUS will indicate connection availability.
  • BUS Display: Instantly and quickly displays all processors, chips, RAM, and other components connected to the SMBUS
  • Internal CPU thermal sensor.
  • Additional thermal sensors or component monitoring.
  • Power monitoring and voltage regulation.
  • DIMM thermal sensors.
  • Platform-specific sensors.
  • Often related to power delivery and monitoring.
  • Serial Presence Detect (SPD) EEPROMs
  • Used for integrated voltage regulators.
  • Specific to some AMD chipset features.
  • integrated voltage regulators.
  • MODE Button: A long press and release initiates processing of the internal firmware of the RAM and provides information about the motherboard configurations and temperature sensors that operate on the same protocol.
  • VDDSPD Indicator: Indicates power status.
  • RST Indicator: Shows whether the reset signal is active low or high.



  • ALEXSOF GENERATOR
  • GEN SPD If 2 jumpers are placed in this place, it will connect the external SPD CHIP that has a place on the back of the tester (two different 8 pins package) with the SMBUS this is useful for motherboards that have one RAM slot.
  • GEN RST If you want to generate a reset signal, place a jumper in this place.
  • PULL RST In case you want a suitable voltage for the reset signal instead of the missing voltage.
  • TEST POINTS THERE ARE 9 IMPORTANT TEST POINTS you can use them directly and easily.

MPS Import & Export & Modify Program :

1739567804966.jpeg






















































Connect the mps chip online using SCL,SDA,GND to the motherboard laptop , pc , gpu card
or solder your mps chip on the offline adapter and connect it to the programmer
Open the MPS software ( download link with the progammer ) , when it is not connected to the programmer, the following red message will showing [USB is not connected!
When the programmer is connected, the [USB is not connected!] will disappear
The programmer is connected to the chip through 3-pin plugs: black line: GND, SDA, SCL If you do not know which specific point, please check the datasheet of the chip or the schematic
Power on the target board, and then point to the SCAN search chip (Note: for online mode the chip must be energized to be recognized!)
Recognize the chip MP2886A, PMBUS address is 20H, Vendor lD is 25H.
If there is more than one chip, it will be displayed in the left list, click the title of the chip to select it
Click [Input], the window shows the basic parameters of the chip, the number of phases ,vboot,PWM-VID, FERQ,RC BOOT,,etc and you can modify them
Click [Reglster], in this interface backup program and write new program or mdify
Backup program: Click [Cur.Export] for the chip you choose
[Sys. Export] this option backup all chip read by the programmer , enter the name of the file to be saved and save it.
[Cur. Epot] is recommended so you can backup each chip seprated
Write Program: (The [Sys. Config] is directly written to the chip, The [Sys. cmd] needs to be written manually by us to facilitate the change of parameters after writing)
Method 1: Click [Sys. cmd], select the program file, open it, import the configuration, click [WRITE TO NVM], and write the program to the chip
Method 2: Click [Sys. Config], select the program file, open it, and then the program will be automatically written to the chip, then the program will be automatically written to the chip.

Does this board have a different option opposed to a CMOS battery.is it a chip. I hadn't pulled the board from the machine but something tells me I won't find a battery on the top side. Google didn't. Show a location that I saw. Needing some help with this notion HDD. Just a m.2
