Problem with KIOXIA EXCERIA G3 Plus - PC startup issues Boot failures during initialization
I'm facing difficulties installing a KIOXCIA EXCERIA G3 Plus NVME drive. The device appears functional and is healthy; no hardware faults detected. Firmware is current, and the PC running Windows 11 has BIOS updated. There are no PSU issues. My target machine already has two SATA SSDs and supports a 5600G CPU with an RX 6600 GPU. It has two available M.2 slots—one connected to the CPU and another at the bottom. The motherboard is ASUS TUF GAMING B550 Plus, and the manual confirms compatibility. M2_2 shares bandwidth with SATA6G_56; once that slot is filled, SATA6G_56 becomes unavailable. Despite testing various configurations, the PC fails to boot no matter which slot I use. It crashes during startup, resets, or shuts down immediately. Initially, I could see the drive in Windows but couldn't initialize it, leading to a crash when trying to run CrystalDiskMark. The drive was installed on another machine that boots and works perfectly. This current setup lacks SATA ports, possibly because the original ports are connected to different devices. I attempted an upgrade to BIOS, enabled PCIE 3.0, but I'm unsure about changes to CSM or SecureBoot settings. I've tried two NVME slots, but both failed to boot. My understanding was that the top M.2 slot wouldn't interfere with SATA6G_56. I acted quickly during a previous upgrade and hope I haven't missed any critical steps.
I'll look into ASPM Support in the BIOS settings. I thought I tried that from Windows, but since I can't even boot, it doesn't help much. Regarding the Gen3 link, perhaps I made an error the previous time but I believe I did it correctly. Then I restored it to Auto. Next time, when I have the PC where I want to install it, I'll double-check everything. It's strange—I don't have any problems with my B450 Gygabyte board even though it has a 5600G CPU, but my PC lacks SATA drives and only has one M2 slot.
For alternative settings, enable NVMe APST under Advanced → NVMe Configuration.
I didn’t have that choice in my BIOS setup. Today’s actions seem unusual. The NVME was placed in the top M.2_1 slot, which is meant for CPU connection. In theory, it shouldn’t interfere with SATA ports—those were also unplugged to avoid problems. I confirmed I’m running the most recent non-beta BIOS, the latest AMD chipset, and the newest GPU driver. I experimented with several settings: forced PCIE 3.0 for all slots, set SB Link to PCIE 3.0, adjusted power management options under NVME and AMD CBS, tried both with and without Secure Boot/CSM, disabled Fast Boot, reset BIOS settings, and more. The outcome was consistent—Windows would start but then shut down before booting. Only after completely disconnecting the PC from power and letting any remaining charge dissipate did it resume normal operation. When I reconnected SATA drives and applied some of these changes, I managed to boot Windows from a SATA SSD (not the NVME), which allowed me to access its files. However, running CrystalDiskMark caused the system to crash immediately under load. It seems there might be a power management conflict, though the PSU appears solid (Corsair model) and the PC can handle the required power. I’m unsure what to do next. I’ve used NVME in another machine without issues, so it’s possible the problem lies with that BIOS or the B550 chipset, possibly linked to the GPU/CPU combo. At this stage, I’m considering trying a different brand to rule out the issue, but I’m hopeful that identifying the correct setting will resolve it.
I understand your point. A recent forum discussion mentioned an NVMe drive failure linked to the power supply unit. Could you share what model of PSU you have?
I'm still unsure about this situation. It seems like a borrowed Corsair, and usually my PC handles stress well. If gaming causes the same problem, it's been working for a couple of years now. The system isn't very demanding. Unfortunately, I don't have another NVME to test, but if this happened with other brands, I'd check the PSU first—though I don't think it's faulty.
I understand, I remember it from three months ago after confirming the drive was functional. It still works on another PC or with a case, and the hardware seems fine. Although it’s not broken, I think it would have been wise to return it earlier and purchase a replacement. I plan to buy more storage before costs rise, since I already own other Kioxia G2 NVME drives that have been reliable for years. The brand is definitely trustworthy.
I checked it by running tests in another environment. From what you've mentioned, the PSU seems highly probable. NVMe power delivery operates independently from GPU power during games, so matching issues across different NVMe setups point to the same source.
