• Multi-threaded testing to saturate all memory channels.
• Persistent logging and test result export for documentation and support requests.
• Test patterns targeted at modern DRAM failure modes (row hammer, bit-flips, coupling faults).
• ECC reporting and analysis on supported platforms to separate corrected from uncorrected errors.
• Hypervisor/VM use: booting the ISO in a VM to test virtualized memory behavior (note: this tests the VM’s virtual memory mapping rather than actual physical RAM unless passed-through).
