Companies choose RAM STRESS TEST for:

Unmatched Accuracy

Unlike other memory test tools that simply throw basic patterns at memory without much thought or knowledge of memory architecture, R.S.T. proprietary memory test algorithms are designed from years of failure analysis to efficently identify the most evasive memory failures.

Behavioral Testing

Utilizing over 30 proprietary test patterns, R.S.T. stress tests and validates memory modules within the system environment, testing for behavioral failures that are sensitive to system idiosyncrasy.

Self-Boot Technology

R.S.T. hardware employs onboard processor, memory and firmware to eliminate any operating system dependencies. Directly boot to the R.S.T. hardware for unmatched low-level testing and accuracy.

Continuously Updated

Firmware updates are available up-to three times a year ensuring the latest technology and components are officially supported.

Universal Support

Supports 98% of all Tablet, Laptop, Desktop, or Server platforms equipped with an Intel or AMD x86 32/64 bit processor.

Piece of Mind

Validation provides the highest confidence in products shipped while minimizing warranty returns and RMAs.

Legacy BIOS Mode

Since being introduced in 1999, RAM Stress Test Legacy BIOS Mode has set the bar on test accuracy and been the de facto standard test and validation tool for the industry.

Frequently Asked Questions

Here are some answers to some of the most common questions we hear.

R.S.T. identifies memory defects that may have passed every usual manufacturing test, but which can still fail in normal use. A major advantage of R.S.T. 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.
R.S.T. supports the latest and greatest DDR memory technologies (DDR4, DDR3, DDR2, DDR, ), ECC, Registered (R-DIMM), Buffered (FB-DIMM) and Load Reduced DIMM (LR-DIMM).
R.S.T. is avilable from our global distributors and may also be purchased directly from the Ultra-X web shop: https://shop.uxd.com and shipped globally.
Every R.S.T. purchase includes:
  • A professional Ultra-X black carrying case
  • RAM Stress Test PCI Express or RAM Stress Test USB hardware
  • Product Firmware Updates for duration of license term
  • Full Product Warranty for duration of license term
