I came here looking for a way to resolve an error "A driver cannot load on this device" for the driver "iqvw64e.sys". This error popped up after I enabled "memory integrity" in Windows 11.

Note that "some malware camouflages itself as iqvw64e.sys" source.

This driver is associated with Intel network connections software, and gets removed by uninstalling the software per this reddit comment in r/sysadmin. This error is probably because Intel won't support Intel PROSet & Intel Advanced Network Services on Windows 11. The driver is likely a holdover from my Windows 10 OS before I upgraded it to Windows 11. The driver is probably unneeded since other Intel drivers are available .

The accepted answer in this Microsoft Q&A forum seems silly (just disable memory integrity), so I kept reading and found the highlighted response which quoted a more sensible answer (get rid of bad drivers). Later in the replies, someone asks what's the most efficient way to remove the driver and someone else states

I found the solution to this problem. After digging for the source of this file, I came across this article. File.net description of iqvw64e.sys. According to the article, this driver can be removed by uninstalling "Intel(R) Network Connections". Sure enough, I went to Control Panel, uninstalled the recommended app, rebooted, and voila! No more error. As for the value of that application, I have no idea. I am however happy to be rid of this error.

This didn't work for my case since "Intel(R) Network Connections" wasn't installed. Couldn't find iqvw64e.sys in the expected location of C:\Windows\System32\drivers. May have been removed after memory integrity enabled?

Presently looks like non-issue and can disregard warning in the future

While the evolution of PCIe speed is definitely of interest, especially as it keeps pace with network speeds, the total number of PCIe lanes also a significant barrier to I/O for many systems... Especially in HPDA.

We can effectively double network throughput by dropping in another 16x NIC. This becomes less possible if there are not enough slots (or perhaps more importantly if available PCIe lanes are oversubscribed). This becomes even more of an issue, as the author points out, with the advent of NVMe.

Intel has a vested interest in keeping the number of PCIe lanes at 40 with Xeon and holding back implementation of PCIe 4.0. They provide proprietary high speed I/O to their Xeon Phi coprocessor and Optane memory products. This doesn't allow GPUs, FPGAs and competing NV memory products to compete on equal footing.

AMD is somewhat breaking the stalemate with Zen Naples offering 128 PCIe 3.0 lanes. Will have to see if OEMs build systems that expose all of that I/O.
