RAMCHECK/RAMCHECK LX Calibration & Hardware Upgrades
Document updated 11-21-17
While most improvements to our products are available to our customers via the Internet through firmware and software upgrades, the continuous changes in memory technology require us to make various hardware and component changes in our products.
We strongly recommend that you have your unit serviced every 12-18 months to make sure that it remains current to factory production specifications and operates at its most optimum level, thereby protecting your investment and ensuring that your test system does not become obsolete.
Additionally, we offer special hardware upgrades soon after we incorporate them in our current production. For example, our most popular special hardware upgrade is currently the required support for DDR2. This document outlines the RAMCHECK Calibration & Upgrade procedure, and will enable you to determine if your RAMCHECK requires an upgrade. It is applicable to both the RAMCHECK and RAMCHECK LX models.
Overview of the Factory Calibration & Upgrade Procedure
You should send in your RAMCHECK/RAMCHECK LX for the Calibration and Upgrade procedure either at regular intervals (every 12-18 months) or upon the emergence of a new test feature that requires a special hardware upgrade. Special upgrades may be recommended to you by our Technical Support department or may be indicated elsewhere on our web site. In any event, please remember to contact us to obtain an RMA number as we cannot accept packages without valid RMA numbers.
Once in the factory, our technicians will inspect all Printed Circuit Boards (PCB) assemblies to identify their revision number. Some old PCB versions cannot be upgraded due to the timing characteristics of those boards' trace layout. Such boards will be completely replaced with new boards; original test sockets and other removable hardware will then be transferred from your original old board. Other PCB assemblies of your unit will be upgraded to current production specification by placing and replacing different components. The unit will go through a 24-hour burn-in process followed by the final Calibration process. This process involves the same final testing and calibration that we perform on every new production unit. After all factory tests have been concluded with a positive result, the unit is returned with the relevant Calibration certificate.
Determining the Need for the Upgrade Procedure
If you elect to perform the periodic Calibration and Upgrade every 12-18 months, you should use the Calibration Date stored in your unit (see below) to determine when to send the unit.
As a registered user, our Technical Support department may notify you when a new feature that requires a special upgrade is available. In some cases, you can determine that you may need a special upgrade if a certain new feature does not work properly on your unit.
To help determine if your unit requires calibration & upgrading, first verify that you have the latest firmware revision (RAMCHECK LX version 3.31/RAMCHECK version 2.64 or higher) by checking our Firmware Download page. If you have a DDR adapter, make sure it is inserted on RAMCHECK and enter the following key sequence during Standby Mode:
You will reach a multi-page Product Information screen which you can scroll up and down using the F3 and F4 buttons. The following table lists the current product information variables for RAMCHECK/RAMCHECK LX:
The actual variables and their order in this table may be changed as we develop new firmware versions. Again, please note that you must have the latest firmware for the following screen examples. Many items in the above information are for reference only. To determine the need for Calibration and Upgrade, you should use the following variables and examples.
PRODUCT INFORMATION DATA (filled-in by customer)
Using the above information, our Technical Support department can determine if you need to upgrade your RAMCHECK, RAMCHECK and the DDR/DDR2 adapter, or just the DDR adapter, and to determine the fixed cost of the service.
Ordering the Calibration and Upgrade Procedure
Please contact our Technical Support department for pricing and to schedule this service. The service part number for ordering is INN-8668P-C-U1.
