RAMCHECK memory tester adapters
RAMCHECK® DDR3 204-pin SODIMM Converter
DDR3 SODIMM tester
The RAMCHECK DDR3 204-Pin Converter (p/n INN-8668-16-1) gives you the ability to test 204-pin DDR3 SODIMM memory found in laptop PCs and other devices. To use, insert the converter into the 240-pin RAMCHECK DDR3 adapter. It works with both the RAMCHECK and RAMCHECK LX memory tester.

This converter tests the popular 64-bit JEDEC-standard DDR3 SODIMM modules using an inexpensive production grade socket of the type used on motherboards. If you need to test a large volume of S.O. DIMM modules, a discounted three-pack of converters is available.

RAMCHECK tester automatically detects the presence of the converter indicating "RAMCHECK DDR3 SERIES" during power on. The module's structure, size and type are are detected automatically. The test flow follows our standard Basic Test, Extensive Test, and Auto-Loop.

Unlike the main 240-pin DDR3 adapter which supports both ECC and non-ECC DIMMs, the 204-pin DDR3 SO-DIMM converter is explicitly designed for x64 (non ECC) SO-DIMM modules. These SO-DIMM modules follow the JEDEC standard (e.g. JEDEC Standard No. 21C Page 4.20.18-1). A small minority of the SO-DIMM modules are ECC (x72 bits) and they have a completely different wiring. We plan to support these modules later when demands increases and their JEDEC standard is finalized.

Specifications

  • Supports Burst Length of 8, BC4 or 8 and BC4.
  • Supports both Read CAS LATENCY (CL) and Write CAS LATENCY (CWL) in the range of 5,6,7,8,9,10,11, and 12. Supports Additive Latency of 0, CL-1 and CL-2. Trcd is supported in the range of 4,5,6,7,8,9 and 10. Default test allows automatic selection of CL and CWL for different test phases. The user can select specific CL values using SETUP or the CHANGE-ON-THE-FLY feature.
  • DDR3 Data rates : 800MHz and 1066MHz. Test engine reaches 1333Mhz on some tests. Higher speed DDR3 modules can still be tested at a lower frequency, as described below.
  • True 1.5V testing with a wide support range of 1.35V to 1.8V at 10mV increments.
  • Controlled Vtt for true STTL-15 compatibility.
  • Parallel testing capability of 64 bits.
  • Three controlled pairs of differential clocks for tested module.
  • Maximum 16 Row/16 Column addresses. Currently, 16GB modules can be tested. Test support is added as larger modules are introduced to the market

When ordering, please reference part number INN-8668-16-1.

Please note that generic motherboard SO-DIMM "extenders" will not work with the DDR3 240-pin adapter. Third-party extenders are not designed to work with INNOVENTIONS test equipment and they lack the proper wiring and circuitry. We do not provide support for these extenders.

DDR3 Frequency Support
The new RAMCHECK DDR3 adapter can perform DDR3 tests at actual test frequencies up to 1066MHz. Modules designed for 1333MHz and 1600MHz (as well as future DDR3-1800, 1866, 2000, etc.) can be functionally tested on the DDR3 adapter but at a reduced frequency. The DDR3 test engine can achieve 1333MHz internal diagnostic speeds. Please see the product specifications for further details.
