For Troubleshooting and Testing PCIe slots
By simply plugging in the card, and powering up, you can quickly confirm if the PCIe slot is correctly powered by way of dedicated indicator LEDs for each power pin on the PCIe connector.
Measure the voltage of the PCIe slot (12V, 3.3V and 3.3Vaux) power rails
Measure the 12V and 5V lines directly from your PSU’s 4-pin Molex or SATA power connector
‘Power Fail’ LEDs paired with voltage sampling indicate whether the voltages are outside of PCIe/ATX power spec without running any software
Benchmark tests use a bus-master DMA controller to maximise test transfer speeds between high speed integrated LSRAM and system RAM up to a maximum theoretical speed of 5Gbps per lane.
Monitor power rails for transient noise/spikes/brown-out using 1MHz dual-channel oscilloscope mode
Check that data can be sent and received from the port
Check PCIe error rates and transmission speed (5Gbits/sec per lane, up to 1200MBps when using x4 edge) in Windows
Benchmark your PC’s PCIe slots
Check if your PCIe slots are Gen2 5Gb/s or Gen1 2.5Gb/s
Fits into any length PCIe slot, can test 1 or 4 lanes at PCIe gen2 speeds
Verify that the system remains stable under long periods of load
Monitor temperature inside the case (0°C to 125°C, ±2°C)
Concurrently check multiple PCIe slots at the same time
