Gigabyte Z390 M Gaming build with working NVRAM

Native NVRAM Available?

If you don't know what NVRAM is, according to Wikipedia: Non-volatile random-access memory (NVRAM) is random-access memory that retains its information when power is turned off (non-volatile). This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM)...

NVRAM is maintained on a small chip soldered to the motherboard. It has nothing to do with NVMe based storage or the DDR4 system ram modules that you install to a motherboard.

The first flash-based SSDs leveraged legacy SATA/SAS physical interfaces, protocols, and form factors to minimize changes in the existing hard drive (HDD) based enterprise server / storage systems.

NVMe is a high-performance, NUMA (Non Uniform Memory Access) optimized, and highly scalable storage protocol, that connects the host to the memory subsystem. The protocol is relatively new, feature-rich, and designed from the ground up for non-volatile memory media (NAND and Persistent Memory) directly connected to CPU via PCIe interface.

Many thanks for the amazing speedy response. This is how I understood it so thanks for the clarification.

My next question: is it possible to install OSX on NVMe drive on this motherboard?

Thanks
Tony

Do you see your USB headphones in System Information > USB? Have you tried different ports?

Please try launching Hackintool, click the USB tab and post a screenshot of what you see.

I plugged the headphones into the rear USB and it worked. Thank you very much) It's strange why I didn't try it right away.

100 % possible.

Thanks so much!

My final research is on fanless graphics card (this is a build for a recording studio).

Does your PC case use USB 2 ports? My USB port configuration is configured such that it assumes your PC case has USB 3 ports.

You can configure the USB ports to your specific configuration by following the guide below:

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

I don't know of any passively cooled graphics cards that are worth purchasing.

I really don't know of any current AMD graphics cards that are passively cooled. I think there were some Nvidia GT 640s, GT 710s, and GT 730s that were passively cooled but they are very old now and the IGPU of your CPU will probably outperform them.

I have a PowerColor Vega 56 Red Dragon in my other build. The fans on that video card do not spin in macOS until the video card is stressed. Even when the fans do spin, they remain inaudible to me unless pushed to very high RPM. I think this might be as close as you will get to a worthwhile, passively cooled graphics card.
