Intel Approved Memory Process
The Intel Approved Memory Module Process allows computer memory manufacturers to submit their modules to get Intel Approved on motherboards from the industry’s leading manufacturer Intel. Memory modules, which pass the CMTL rigorous incoming inspection, and Intel Approved criteria, are then awarded recognition as a Intel Approved Memory Module, and can use the Intel Approved Memory seal.

Memory modules that have completed all the testing phases under the Intel Approved Memory Module process are known to be compatible with the Intel motherboards on which they were tested, and will be listed as “Intel Approved” on the CMTL website and Intel web site since they got tested on Intel motherboards.

 Advanced Tested Modules

Intel Approved Memory
Every Intel Approved Memory module is put through extensive incoming inspection and Intel Approved compatibility testing to minimize any incompatibly risks. The Intel Approved memory process requires the module to be Intel Approved and Tested for compatibility in many of the available motherboards using a variety of processors and chipsets to ensure compatibility. Only modules that pass this in-depth set of checks and tests can receive the Intel Approved seal of compatibility, this is your guarantee of a quality memory module.

Minimum testing hours required to receive Intel Approved Memory Module Certification:
      NUC Memory Module: 24 hours of testing
    
Server Memory Module: 24~48 hours of testing

Requirements for Intel Approved Certification

NUC Memory

  1. Module part number and BOM must successfully pass all incoming inspection checks and verification of industry compliance to include form, fit, and function, device configuration, PCB layer count, PCB part ID, DRAM part ID, PLL manufacturer, Rank, CAS latency timing, device speed, and SPD programming.
     

  2. Each module part number and BOM must complete and pass a minimum of 48 hours of Intel Approved compatibility testing.

Server Memory

  1. Module part number and BOM must successfully pass all incoming inspection checks and verification of industry compliance to include form, fit, and function, device configuration, PCB layer count, PCB part ID, DRAM part ID, PLL manufacturer, Rank, CAS latency timing, device speed, and SPD programming.
     

  2. Each module part number and BOM must complete and pass a minimum of 48 hours of Intel Approved compatibility testing.

What’s an Intel Approved Memory Module and how is the test performed?
Each memory module that’s tested in CMTL’s Testing Laboratory goes through extensive physical and environmental testing that includes various combinations of the following tests depending on the module and the motherboard for which they are tested in:

Paper Screening (performed by the manufacturer)
A paper screen is a review of critical timings, electrical characteristics, timing requirements, environmental requirements, and packaging requirements in order to see if the DIMM meets the memory specifications.

Physical Dimensions Testing
Each memory module that is submitted for testing is meticulously checked and measured to ensure compliance with proper PCB manufacturing standards and practices.

SPD Screening
The SPD contents test ensures the SPD EEPROM is programmed properly and is in compliance with all the current industry standards. The modules must also be fully compatible with the motherboards in which they are tested in and will be checked to ensure proper identification and functionality in the motherboard is made.

Power Cycling Test [AC or DC Cycling]
Power cycle testing involves powering on and off the motherboard platform for 50~100 cycles. This test checks the memory modules ability to be cycled and makes sure the board or system will boot properly an indefinite number of times without errors. This test verifies board or system response to different DIMM sizes, module organization, volatile register, memory caches, RAM, and amount of memory installed on the board.

S0~S5 (suspend to RAM) Test

The S0~S5 test is performed to ensure that the memory modules being tested are correctly refreshed by the motherboard and are capable of retaining their contents through a power management state. The motherboard and memory modules interoperability is tested to see that no test data is lost or corrupted during the testing.

  • System Power State S0 the ON state: The system is completely operation, fully powered and completely retains the context.

  • System Power State S1 the Sleep state: The system consumes less power than S0 state. All Hardware & Processor context is maintained.

  • System Power State S2 the Sleep state: The system consumes less power than S1 state. Processor loses power and processor context and contents of the cache are lost.

  • System Power State S3 the Sleep state: The system consumes less power than S2 state. Processor & Hardware context, cache contents, and chipset context are lost. The system memory is retained.

  • System Power State S4 the Hibernate state: The system consumes the least power compared to all other sleep states. The system is almost at an OFF state, expect for a trickle power. The context data is written to hard drive (disk) and there is no context retained.

  • System Power State S5 the OFF state: The system is in a shutdown state and the system retains no context. Note that in power state S4 the system can restart from the context data stored on the disk, but in S5 the system requires a reboot.

Elevated Temperature & Voltage Margining Functional Testing
The elevated temperature testing and voltage margining tests involve testing the memory modules on the motherboard for which it is being tested while fluctuating memory power voltages (+/-3~5% depending on the motherboard) to the memory modules under test for extended periods of time during elevated temperatures (0c to 55c). The test involves testing the memory modules and memory sub system on the motherboard while running Intel Proprietary test software and additional memory stress software under these harsh conditions. Each memory module test cycle typically last from 12~48 hours for server platforms.

The Value Of Intel Approved Memory
In order to obtain Intel Approved, each memory product is subjected to Intel exacting test procedures. This is a guarantee that every Intel Approved Tested Memory module is compatible with the motherboard for which it was tested. Memory modules which are NOT Intel Approved for compatibility and functionality may experience erratic and inconsistent functionality which can negatively affect overall system reliability. This loss of reliability can be the result of issues involving:

  • Module design

  • Component selection

  • SPD programming

  • PCB structural integrity

  • Manufacturing, and quality control processes

The Intel Approved Memory testing process can detect these potential problems, providing resellers, manufacturers and consumers the confidence of a Intel Approved Memory Module.
