Exactly. The performance of a chipset PCIe 4x4 NVMe slot was half that of an NVMe drive in an adapter plugged into the CPU PCIe 4x4 slot. (I checked it over a year ago?”maybe it's better with BIOS updates or the B850.) You don?™t know what kind of controllers you?™ll be able to install in three years, so having PCIe 4x4 wired to the CPU is a must. I suspect running USB4 controllers through a chipset 4x4 lane is nonsense, even today. I have better sound cards in my monitors than the onboard one. It's crazy that people still buy ATX boards in 2025 with an inferior PCIe lane configuration and think they have more features. :) |

The PEG release mechanism is impossible to reach without a tool with a tower cooler installed, and a screwdriver isn't recommended.
Also, how do I boot an old Windows install that's on a SSD with a MBR partition table? I've enabled CSM but the screen basically stays blank after the BIOS message. |

Hard to tell if it is stalls at bios or os boot. I would recommend converting to GPT and/or migrating this install to VM. Edited by M440 - 06 Apr 2025 at 3:47am |

It's not that old, it's my regular W10 install from the old system. I'd rather not re-install Windows / all apps, though I'm aware it's recommended.

There's now a R2.0
What changed? |

I see ZERO difference in the Specification pages between the original and the R2.0. WRONG! PCIe x16 slot went from Gen.4 to Gen.5.
I also compared all the Gallery photos, and the only differences are the main PCIe slot cover design, and some silkscreen differences. RTC battery warning mark moved, and the logo changed a bit. Ahh! I see it. Original's main PCIe x16 slot is limited to Gen.4. R2.0's main PCIe x16 slot supports Gen.5. I imagine this is to keep up with what Gigabyte is doing. I'm not sure if there is actual trace difference or not. I do see that the slot has a different metal design, but I don't know if it's required to support faster PCIe speed. If someone is brave, try forcing the R2.0 BIOS onto the original and see if it supports PCIe x16 Gen.5 (laugh). Edited by eccential - 9 hours 49 minutes ago at 8:53pm |
