Ramcheck ddr2

Highly modular and user friendly, the RAMCHECK LX redefines the capabilities of an affordable and portable memory tester. The newly designed 184-MHz test engine and scalable data interface provides faster tests and gives you a higher resolution of timing measurements. RAMCHECK's architecture has been optimized to better support the memory devices of today and tomorrow. With the technology built into the RAMCHECK memory tester, it has become the core foundation from which we have been able to develop several platforms of memory tester adapters.  RAMCHECK with its four expansion sockets is a highly expandable and modular tester.  We are continuously developing more optional adapters to support future memory technologies.

We can test 184-pin DDR1 memory modules up to 466MHz and now our latest development is an adapter to test 240-pin DDR2 and DDR3 memory modules. Other optional RAMCHECK adapters support numerous types of memory devices, including 144 & 200-pin SO DIMMs for Laptops, older 72-pin SIMMs, individual chips, and more.

The Ramcheck LX base memory tester combined with different adapters have become several of our main products.  The RAMCHECK LX DDR1 (INN-8668DDR-PRO) is the Ramcheck LX base tester (INN-8686) combined with the RAMCHECK PRO 184-pin DDR1 adapter (INN-8668-9).

Our latest development is the DDR2 adapter which when combined with the RAMCHECK LX base unit becomes the RAMCHECK LX DDR2.  If you need to test both DDR1 and DDR2 we have a solution for that as well. This is the RAMCHECK DDR2 (INN-8686-DDR2) and the RAMCHECK DDR PRO adapter (INN-8668-9) and is called the RAMCHECK LX DDR2/1 Bundle (INN-8686-DDR2/1 BUN)

By using the enhanced proprietary algorithms of RAMCHECK to run a thorough test by testing every cell in today's and tomorrows memory modules. To yield a faster test, all chips are tested simultaneously to enable the tester to detect errors that are caused by interference among the chips on the module.

RAMCHECK is much more than a PASS/FAIL tester. In fact, it specifically identifies the faulty bits within a defective module and gives pin number relating to the problem chip. While 100% accuracy in memory testing is technically impossible, RAMCHECK achieves a high degree of accuracy in detecting bad memory devices.

The RAMCHECK is usually used by itself or it can be hooked to a PC via a serial cable  and the PC Communication software that comes with the tester will allow it to print and log test reports.  RAMCHECK can easily be upgraded and expanded to protect your investment. This goal was achieved using modern FLASH EPROM technology and a PC Windows companion program. The software also allows the memory tester to update its firmware via the Internet.

Communications Software

Since RAMCHECK is fully automatic and user friendly, anyone can use it with great ease. Its full graphics LCD display shows clear instructions and test results. It has a Zero Insertion/Removal Socket for 168-pin DIMM modules. Add-on adapters employ a similar high-quality socket for the DDR2 Adapter, DDR1 Adapter, 144-pin SO DIMMs, or older style 30-pin and 72-pin SIMMs.

A single button starts the fast BASIC test which automatically measures and displays the module Type, Size, Mode, Access Frequency, Cycle Time measurement and more. The BASIC test verifies that all memory cells are sound and checks the wiring of the modules. The EXTENSIVE test automatically follows with Voltage Bounce and Cycling that tests and verify the module performance under varying voltage conditions. The March Up/Down algorithm detects interference among cells. Various tests like Relative Refresh and Relative Spikes provide detailed insight into the quality of the tested module. The AUTO-LOOP test provides the perfect burn-in means for your memory modules, as well as additional pattern testing. Our proprietary Chip-Heat mode automatically warms the chips for temperature related speed measurement at the end of EXTENSIVE test. The AUTO-LOOP test provides the perfect burn-in means for your memory modules, as well as additional pattern testing. RAMCHECK incorporates additional setup capabilities to satisfy the needs of even the most advanced and demanding engineers.


These actual RAMCHECK display screen images illustrate its ease of use, power, and versatility.

Screen Image Clearly identifies good or bad modules in addition audio high pitch beeps when modules are good and low pitch sounds for error signals.
Screen Image Scrollable error menus and its associated pin number on the graphic display.
Screen Image Explicitly shown address wiring errors.
Screen Image Any changes from standard devices are clearly shown.
Screen Image The Basic Test indicates which control signals are used at the end of the test.
Screen Image A detailed Test Log can be viewed after every test by simply pressing F4 including all the test results.


RAMCHECK tests have been enhanced significantly over our previous generation memory testers resulting in more support for today's and tomorrows memory devices, in addition to added test results not available before.
Screen Image BASIC Test quickly checks all the wiring and all the memory cells in SDRAM, DDR1 and DDR2 memory.
Screen Image EXTENSIVE Test has many featured tests that provide more information on the quality of the memory modules.
Screen Image AUTO LOOP Test which is perfect for burn-in operation, checks the memory with endless changing patterns.


Screen Image Menus for setup and other operations are clear and interactive.
Screen Image Most advanced users will be very pleased with the graphic setup of timing parameters
Screen Image Detailed setup list keeps track of all (optional) changes you made to the default program.
