R.S.T. 4 Premium PCI-Express

R.S.T. 4 Premium is the definitive memory diagnostic and validation tool designed for the rigorous testing needs of memory manufacturers, system builders, design engineers, and service professionals.

R.S.T. Premium ADVANTAGE

Memory is one of the most notoriously difficult core system functions to troubleshoot, exercise, and validate. PC’s are not only being equipped with increasingly large amounts of RAM but their often complex system hardware and software configurations can make it even more difficult to determine if a problem is truly a RAM failure. Such problems vary with different combinations of chipsets, processors or motherboards. R.S.T. 4 Premium's capabilities far exceed those of stand-alone testers in meeting all of these challenges.

SELF-BOOT TECHNOLOGY

R.S.T. Pro4 directly executes using Ultra-X’s exclusive Self-Boot Technology™ eliminating interference from memory drivers, TSRs, O/S limitation, and all other software layers. Utilizing direct hardware to hardware access commands, R.S.T. Pro4 is able to perform true precise low-level memory testing and validation.

BEHAVIORAL TESTING

A major advantage of R.S.T. Pro4 compared to stand alone testers, is the capability of testing and validating RAM within the system environment, testing for Behavioral failures that are sensitive to system idiosyncrasy. Quickly isolate intermittent failures that do not necessarily prevent a system from booting, but surface during extended testing sessions.

EXCLUSIVE MEMORY TEST ALGORITHMS

There are many good approaches for testing memory. However, many tests simply throw basic patterns at memory without much thought or knowledge of memory architecture. As Tier 1 partners with industry leading manufacturers, Ultra-X, Inc. is able to continuously develop new sophisticated proprietary memory test algorithms to locate the most evasive memory failures. R.S.T. 4 Premium has the broadest range of algorithms, for current and future memory chip technologies.

When quality is impererative, choose the right tool!

Features

Below are just a few highlighted features & benefits.

Self-Boot Technology

Accurate true low-level diagnosis and validation cannot be achieved with test tools that require a preloading of Operating Systems. Utilizing Ultra-X's propietary Self-Boot Technology, R.S.T. 4 Premium can execute without interferences from drivers, TSR's, O/S API, or other software layers. This allows testing in the cleanest environment and maximum coverage of CPU & Memroy range on all PC's.

Memory Burn-In/Aging Function

Performs the most comprehensive tests available for Base and Extended Memory (up to 2TB for PCIE and 128 GB for USB). Performs over 100+ different industry standards and proprietary memory testing algorithms. Provides graphic display to pinpoint exact location of failure.

Onboard Memory

R.S.T. Pro4 loads itself into the least amount of RAM possible, occupying far less RAM than any other memory test product boosting similar functionality. Test system RAM without the interference of any Memory Drivers, TSRs, O/S limitations, or Windows protected mode.

Supported Memory Technologies

Enhanced to test the latest DDR4 modules and also supports all SIMMs, DIMMs, RIMMs,(SDRAM, DDR, DDR2, DDR3, FB-DIMM, RDIMM, LVDIMM, RDRAM(RAMBus), SRAM, ECC(PCIE only), Parity and Non-Parity).

Real-Time Temperature & Voltage Measurements via Onboard Sensors

Temperature & Voltage measurement capability. Onboard precision sensors for measuring all critical voltages and ambient temperature.

Real-Time Benchmarking

R.S.T. 4 Premium includes several benchmarking tools to identify system performance & bottleneck areas. Benchmarks can be used to check , optimize, and fine-tune a system's speed under various operating conditions. Comparative data provided by the benchmarks can be invaluable in comparing different technologies and optimizing systems.

Remote Data Logging via Onboard RS-232 Serial Port

Route test results or monitor Real-Time voltage and temperature values to a remote system.

SPD(Serial Presence Detect) Reader

Provides an SPD reader function which displays information on installed memory modules that include Speed and Configuration values.

Memory Map Scanner

Scans base RAM for all programs loaded into memory including; BIOS, Video BIOS, drivers, and any TSRs. Also helps for resolve memory conflicts in base addresses.

PCI Editor

This utility consists of a scrollable byte-level display that allows you to locate PCI registers and change them to the desired setting. This function can be extremely helpful in changing the system configuration and re-testing the system to catch configuration caused memory failures. This function helps save time by bypassing the BIOS CMOS setup program.

Chipset Noise Generator via optional PCI Gen

Optional PCI Gen companion card allows direct memory transfer from PCI Bus to RAM. An ideal solution to detect any chipset level issues.

Behavioral Testing

A major advantage of R.S.T. 4 Premium over high-priced ATE-only testing is that R.S.T. 4 Premium is designed to test and identify problems in memory modules from inside the motherboard environment. Memory that may have passed every usual manufacturing test can still fail in a motherboard normal use environment. This type of testing is called behavioral testing which detects failures that are sensitive to system idiosyncrasy.

Immediate ROI Savings- Reduce Support Costs & Minimize PC Returns

R.S.T. 4 Premium assures the quality and reliability of your PCs memory throughout the entire PC lifecycle; Manufacturering, Development, Support, Service & Repair, and Recycling. Minimize unneccessary RMA returns due to software and NTF/NDF(No Trouble/Defect Found) issues. Reduces support and warranty costs while improving user satisfaction and confidence.

Up-to-Date Technology

Unlike other memory test tools, R.S.T. 4 Premium is continuously updated staying up-to-date on the latest memory technology before hitting the market. With close key relationships with industry leading manufacturers, Ultra-X is able to ensure compatibility with the latest technology.

Comprehensive Testing & Validation

R.S.T. 4 Premium evaluates memory modules through a rigorous testing process to ensure the reliability, integrity and compatibility of its design. Isolate intermittent failures that don't necessarily prevent a system from booting, but surface during extended testing sessions. R.S.T. 4 PRemium will provide the same comprehensive, precise and accurate memory testing ensuring failure correlation exists throughout the lifecycle.
