- detaro 8y agoGood to know, in the past it has been kind of random where motherboard manufacturers enabled it.
- wtallis 8y agoI've encountered a Threadripper motherboard that lacked the firmware capabilities necessary to use a passive PCIe x16 to quad M.2 board. I also haven't seen those quad-M.2 boards listing support for the mainstream Ryzen (AM4) platform, only the Threadripper and Intel HEDT platforms. Have you gotten an AM4 Ryzen system to split its x16 slot into 4x4?
- vetinari 8y agoTR4 boards that were released at TR launch day might miss the firmware support for PCIe bifurbication in the initial release. However, it was added in the later firmware releases.
- Teknoman117 8y agoYes, but now that I look it up it's apparently a feature restricted to X370 and X470 boards. Doesn't really make sense to me considering the PCIe comes off the CPU.
