Passmark PCIe Gen2 Test Card

Nein. Obwohl PCIe-Karten in Bezug auf die Software PCI-Legacy-kompatibel sein können, können PCIe-Karten nicht in PCI-Steckplätze eingesetzt werden, da sie unterschiedliche Pin-Konfigurationen haben und die Steckplätze unterschiedlich belegt sind. PCIe-Zusatzkarten müssen neben ihrem PCIe-Edge-Anschluss eine Interferenzlasche enthalten, um ein versehentliches Einsetzen in PCI-Steckplätze zu verhindern.

A PCIe slot looks similar to a PCI slot, however, compared to PCI slots, PCIe slots generally have a lower profile, slightly different key spacing, and are keyed on the opposite end. PCIe slots can range in length from x1 (1 lane) to x32 (32 lanes). See Figure 2 for a side-by-side comparison of a x16 PCIe slot, a x1 PCIe slot, and a PCI slot.

The PCIe test card has a x1 and a x4 border. The x1 Edge can be inserted into any PCIe slot (x1 and higher). The x4 Edge can be inserted into any PCIe slot x4 and higher. PCIe cards cannot be inserted into slots shorter than the length of their edge connectors.

The PCIe test card can be tested in any generation of PCIe slots. The PCIe test card operates at speeds up to gen2.0 (5 Gbit/s per lane). The capabilities of a PCIe connection depend on the highest speed features that both the endpoint and the host can agree on. When the PCIe test card is inserted into a gen2.0 slot, it will run at gen2.0. When inserted into a gen3.0 slot, the card will limit it to gen2.0 performance. If inserted into a gen1.0 slot, it will be limited to gen1.0 performance by the slot.

• Windows 7, 8, 10 and 2008 Server (in 32bit and 64bit).
• Linux is also supported.

A 6-pin PCIe cable delivers 75 watts and an 8-pin can deliver 150 watts, so splitting the cable doesn't seem like a good idea. But before we draw that conclusion, let's do some calculations.
The PCI-E connector has 6 pins. They are not all used for power. With a 6-pin connector, pins 1 and 3 are connected to 12V and can each carry 8A of current. Pin 2 is not connected by default, although most PSU manufacturers add a 12V line there. Pins 4 and 6 are common returns. Pin 5 is ground for the sensor. Using 2 lines with standard pins gives 12V*8A*2= 192 watts, so the actual limit is much higher than the artificial limits (75 watts). As of March 2005, Molex pins must be "HCS" rather than "Std", each capable of carrying a maximum of 11 amps. So a properly made 6-pin PCI-e cable can provide 12V*11Amps*3 lines=396 watts of power for the graphics cards. The output cable that comes with the tester consists of plus HCS pins with 16AWG wires and is rated for 13A. So assuming decent quality cables are used and there are only 2 live 12v lines, you can use a splitter with high end dual connector GPUs for short term use. Quality splitters are safe to use when there are three live wires in the power supply cord.

A device driver is required for Windows and Linux. It comes with the maps on a mini CD or can be downloaded. Windows requests the device driver when a card is used for the first time. The installation process is covered in the installation guide.

For Windows 7 and 8 you need a device driver. For Windows 10, using the native inbox driver (Microsoft driver) is recommended.

PCIeTest and BurninTest Professional v8.1.1000 and later will work with any version of the PCIe Test device driver, but using the latest version is recommended.

Yes, you can see the devices in Windows Device Manager. They appear with the label "PassMark PCIe Test Card".

• Make sure the PCIe test card is properly inserted into the PCIe slot (see Figure 1).
• Check for PCIe voltages (B1, B2, B3, A2, A3, B8, A9, A10, 3.3V AUX LEDs should be on).
• Some BIOS implementations allow enabling a power management protocol called Active State Power Management (ASPM) that puts the card in a sleep mode before the operating system is loaded. Make sure Active State Power Management is disabled in BIOS.

Each power indicator LED corresponds to a power connector on the PCIe edge connector. Each PCIe connector and each PCIe card therefore has five +12V, three +3.3V and one 3.3V AUX contact/pin. (Multiple pins per power rail allow for higher current capacity (1.1A per pin) to meet PCIe power delivery requirements.) Dedicated power pin LEDs indicate if pins in the connector are not making contact or are not providing additional current.< /p>

PCIe slots are required to provide two power rails: +12V and +3.3V. An optional 3.3Vaux rail is often also present.

The 3.3V auxiliary rail is an optional power rail intended to provide low-speed auxiliary signals such as the optional WAKE# signal.

Out of specification voltage measurements are presented to the user in four different ways.

The red "Voltage Fail" LEDs on the top of the PCIe test card will light up automatically when it detects that the 12V PCIe, 3.3V PCIe, 12V Molex or 5V Molex voltage rails are outside of the specified range (see table above). In this application scenario, no communication with the driver or the application PCIeTest.exe is required.

For more detailed voltage data, the PCIeTest.exe application can track the measured minimum and maximum voltages of all inputs, including 3.3 Vaux and temperature, even during benchmark and loopback tests.

You can directly measure the 12V and 3.3V PCIe power rails with an external voltage measurement device such as a multimeter or an oscilloscope. The power rails can be tested by connecting the tool's probe pins to the labeled jumper headers (+12V, +3.3V, and GND) on the PCIe test card.

Finally, with PCIeTest.exe in "voltage mode" the user can monitor up to two voltage rails or real-time temperature. A green band is superimposed on the output graph to indicate if the measured voltage falls within the acceptable range. "Voltage mode" tracks the number of out-of-range spikes detected.

Yes, you can run multiple instances of the PCIeTest application at the same time, but you must ensure that you have opened and configured them all to use the correct PCIe cards before running the first test.

No. The Molex/SATA power supply only needs to be connected if you want to measure the +12V and +5V power supply rails. If there is no connection, assume that the red "Power Fail" and green "Power" LEDs corresponding to these rails are on and off, respectively.

• Yes, when running the loopback test, the PCIe test application reports the following low-level errors:

Based on the severity, the PCIe errors reported by the application are categorized as follows:

This means that a DMA transfer did not complete successfully and timed out.
