Doing any repair work on your computer, or building one from scratch, is rather easy, but only as long as you know what you’re doing. One wrong or loose connection can damage your parts which won’t be cheap to fix. 

In this article, we’re talking about the R720xd PCIe training error, its causes and what you can do to fix the problem. 


What causes R720xd PCIe training error?

Loose PCIe connections between the slot on your motherboard and the storage device generally trigger the error. That said, mechanical damage to the PCIe slot or the motherboard can also cause this problem.

How to fix R720xd PCIe training error?

Here are three fixes you can try out. 

Check the connections

First, check to ensure everything is properly connected and firmly in place. If there are any loose connections, put them firmly back in place and make sure any screws or mechanisms that hold your drives in place are engaged. 


Check processor compatibility 

The error can also arise because of incompatibility issues between newer processors and older PCIe cards. While most hardware should be backward compatible, sometimes the microcode of newer processors doesn’t sit well with older PCIe cards or devices, causing this error. 

Check to ensure that your hardware is compatible with your processor. If not, your best bet is to upgrade the PCIe device or downgrade the processor. 


Inspect the motherboard

Inspecting the motherboard is also important for troubleshooting anything wrong with any of the slots on the board. Check to see if any of the capacitors near your PCIe slots are swollen or show signs of damage. Also, check the rest of the board for physical damage, as that can impact the PCIe communication lanes. 

If you see something broken or wrong, we recommend you take your motherboard to an authorised repair centre. Changing out smaller parts like capacitors on your motherboard requires experience, precision and specialised equipment. That said, if you do possess these, you can take a shot at repairing the board yourself.
