NEW! MiniPCIE Technology
R.S.T. Pro MiniPCI utilizes Mini PCI Express Technology, perfect for the newest mobile platforms such as Notebooks, Laptops, & Tablet PC's.
ENHANCED! Memory Burn-In Solution
Provides an unattended Burn-In mode for lengthy troubleshooting sessions and new RAM installation verification testing
EXCLUSIVE! Operating System Independent
Onboard firmware eliminates operating system dependencies. Directly runs using proprietary Self -Boot Technology without the need for ANY operating system for superior low level testing
EXCLUSIVE! Onboard Memory
Test system RAM without the interference of any Memory Drivers, TSRs, O/S limitations, or Windows protected mode. R.S.T. PRO MiniPCI loads itself into the least amount of RAM possible, occupying far less RAM than any other memory test product boosting similar functionality
ENHANCED! SPD (Serial Presence Detect) Data of DIMM Modules
Provides SPD information on installed memory modules that include Speed and Configuration values
EXCLUSIVE! Real-Time Benchmarking
R.S.T. PRO Mini PCI Express 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
EXCLUSIVE! Memory Map Scanner
Scans base RAM for all programs loaded into memory including; BIOS, Video BIOS, drivers, and any TSRs
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
