**Date**: 2026-04-02
**Purpose**: Research latest firmware/BIOS versions for all components and assess update needs.
## Summary
| Component | Current Version | Latest Version | Update? | Risk |
|-----------|----------------|----------------|---------|------|
| Motherboard BIOS | F53 (2025-10-28) | F53 | **No** | - |
| NVMe SSD (PM9A1) | GXA7401Q | **GXA7801Q** | **Yes (applied)** | Medium |
| SATA SSD (840 EVO) | EXT0BB6Q | EXT0BB6Q (EOL) | **No** | - |
| GPU VBIOS (GTX 1050 Ti) | 86.07.39.00.50 | 86.07.39.00.50 (EOL) | **No** | - |
| NIC (RTL8111) | rev 0c, r8168 driver | Kernel-integrated | Via kernel | Low |
| CPU Microcode | Kernel-integrated | Kernel-integrated | Via kernel | Low |
| USB Peripherals | Various | Various | **No** (no LVFS) | - |
**Actionable updates**: 1 (NVMe SSD firmware)
---
## Detailed Findings
### 1. Motherboard BIOS: Gigabyte AX370M-DS3H-CF
| Field | Value |
|-------|-------|
| Current | F53, dated 2025-10-28 |
| Latest | F53 (no newer version found) |
| Source | [Gigabyte Support](https://www.gigabyte.com/us/Motherboard/GA-AX370M-DS3H-rev-1x/support) |
**Status**: **Up to date.** F53 from October 2025 is the latest available. The AX370M-DS3H (rev 1.x) is an AM4 board from 2017 - F53 represents a remarkably long support timeline (8+ years). No further updates expected.
**Update method** (if future versions appear): Q-Flash (BIOS) or @BIOS (Windows/Linux utility).
---
### 2. NVMe SSD: Samsung PM9A1 (MZVL2512HCJQ-00B00)
| Field | Value |
|-------|-------|
| Current | GXA7401Q |
| **Latest** | **GXA7801Q** (non-SED, `00B00`) |
| Source | [GitHub: samsung-nvme-firmware](https://github.com/lolyinseo/samsung-nvme-firmware) |
**Status**: **Update applied 2026-04-02.** GXA7801Q is the correct firmware for non-SED PM9A1 drives (model `00B00`). Reboot pending to activate.
> **Important**: GXA7802Q is for SED drives (model `00B07`) only. Our non-SED drive (MZVL2512HCJQ-**00B00**) requires GXA7801Q.
> The OVHCloud mirror only hosts GXA7802Q, which was rejected as "Invalid Firmware Image".
### Firmware Naming Convention
| Suffix | Type | Model Suffix |
|--------|------|-------------|
| `GXA***1Q` | Non-SED (standard) | `00B00` |
| `GXA***2Q` | SED (Self-Encrypting) | `00B07` |
### Firmware Changelog (GXA7401Q → GXA7801Q)
| Version | Key Changes |
|---------|-------------|
| **GXA7401Q** (current) | Fixed Pyrite spec violation (prevented user data erase during TCG revert). Improved write performance drop beyond 70% capacity usage via foreground GC in SSB area. |
| **GXA7602Q** | Changed LPN per Unmap Range from total device LPN to 1000. Improved free block generation, reduced unnecessary migrations and TLC writes. |
| **GXA7702Q** | Increased LPN per Unmap Range to 10,000. Introduced **side effects**: lengthened FW time for Unmap operations, slower free block generation, increased unnecessary migrations. Samsung recommended **holding** this version. |
| **GXA7801Q** (latest, applied) | **Fixes all GXA7702Q side effects.** Non-SED variant. Corrects unmap handling, restores free block generation performance. Released ~Nov 2022 after internal qualification. Overall stability and performance improvements. |
**Key benefit for workstation**: The GXA7401Q → GXA7801Q jump fixes unmap/TRIM performance regression chain from GXA7702Q intermediate versions. Since this is a root NVMe drive with heavy I/O, improved unmap handling and write stability are relevant.
**Note**: No official Samsung changelog exists publicly. Information sourced from Samsung internal PDF (gzhls.at), OVHCloud deployment guide, and Win-Raid community.
**Update procedure** (Linux, no Samsung Magician needed):
```bash
# 1. Install nvme-cli
sudo pacman -S nvme-cli
# 2. Verify current firmware
nvme list
# 3. Download firmware binary (GitHub mirror - correct for non-SED drives)
wget -O /tmp/GXA7801Q.bin \
"https://raw.githubusercontent.com/lolyinseo/samsung-nvme-firmware/main/PM9A1/ASUS/GXA7801Q/GXA7801Q_20221102.bin"
# 4. Apply firmware (ensure NVMe is /dev/nvme0n1)
sudo nvme fw-download --fw=/tmp/GXA7801Q.bin /dev/nvme0n1
sudo nvme fw-commit -s 2 -a 0 /dev/nvme0 # Install to slot 2
sudo nvme fw-commit -s 2 -a 2 /dev/nvme0 # Activate slot 2
# 5. Reboot to apply
sudo reboot
# 6. Verify after reboot
nvme list
```
**Update applied**: 2026-04-02 10:51 CET. All three nvme-cli steps succeeded. Reboot pending.
**Firmware file**: SHA256 `76ad2b0c35581cb71bd4c5a5fd358a15c4432aa38e9e983acc2349d2b24b5a11`
**Risk**: Medium. NVMe firmware update can brick the drive if interrupted (power loss). Original firmware GXA7401Q preserved in slot 1 as fallback.
**Pre-firmware benchmark**: See `docs/tech/nvme-benchmark-pre-gxa7802q.md`
---
### 3. SATA SSD: Samsung SSD 840 EVO 500GB
| Field | Value |
|-------|-------|
| Current | EXT0BB6Q |
| Latest | EXT0BB6Q (EOL - no updates since ~2015) |
| Source | [Samsung Semiconductor Tools](https://semiconductor.samsung.com/consumer-storage/support/tools/) |
**Status**: **No update available.** The 840 EVO (released 2013) has reached end-of-life. EXT0BB6Q is the final firmware. No further updates will be released.
**Note**: This drive is 12+ years old. Consider monitoring health via `smartctl` and planning replacement if reliability degrades.
**If update were needed**: Samsung provides bootable ISO firmware utilities, but none exist beyond EXT0BB6Q for this model. Samsung Magician is Windows-only.
---
### 4. GPU: NVIDIA GeForce GTX 1050 Ti
| Field | Value |
|-------|-------|
| Current VBIOS | 86.07.39.00.50 |
| Latest VBIOS | 86.07.39.00.50 (EOL) |
| Current Driver | 575.64.05 |
| Latest Driver | ~580.81 (final for 10-series, end of 2025) |
| Source | [NVIDIA Drivers](https://www.nvidia.com/en-us/drivers/) |
**Status**: **No VBIOS update available.** NVIDIA ended Game Ready driver support for GTX 10-series at end of 2025. No VBIOS updates have been released.
**Driver note**: Driver 575.64.05 may be close to or past the final supported version. Check `mhwd` or `pacman` for the latest NVIDIA 10-series driver available in Manjaro.
**Update method** (drivers only): `sudo pacman -Syu nvidia` or via Manjaro Hardware Detection (`mhwd`).
---

## fwupd Status
**Installed**: fwupd 2.1.1 (2026-04-02)
### Detected Devices (7 total)
| Device | Type | Current Version | Updatable via LVFS? |
|--------|------|-----------------|---------------------|
| MZVL2512HCJQ-00B00 | NVMe SSD | GXA7401Q | Yes (flag) / No update published |
| SSD 840 EVO 500GB | SATA SSD | EXT0BB6Q | Yes (flag) / No update published |
| Ryzen 7 2700X | CPU Microcode | 0x0800820e | No |
| AMD TPM 2.0 | TPM | 3.8.0.3 | Yes (flag, signed payload) |
| Unknown (PNP:WOR) | Display (?) | - | No |
| Unknown (PNP:BNQ) | Display (?) | - | No |
| Unknown (PNP:WOR) | Display (?) | - | No |
### LVFS Update Check Result
```
No updatable devices
```
Samsung does not publish PM9A1 or 840 EVO firmware on LVFS. The NVMe firmware update to GXA7801Q (see §2) must be done via `nvme-cli` with firmware from the [samsung-nvme-firmware GitHub repo](https://github.com/lolyinseo/samsung-nvme-firmware). The OVHCloud mirror only has GXA7802Q (SED variant, incompatible with non-SED drives).
### New Discovery: AMD TPM 2.0
fwupd detected an **AMD TPM 2.0** device (version 3.8.0.3) not in original inventory. This is the firmware TPM (fTPM) built into the Ryzen processor. It supports signed payload updates via fwupd/LVFS. Currently no update is published.
### fwupd Verification Commands
```bash
fwupdmgr refresh # Refresh metadata from LVFS
fwupdmgr get-devices # List all detected devices
fwupdmgr get-updates # Check for available updates
fwupdmgr update # Apply available updates
```
---
## Recommended Action Plan
### Immediate (Low Risk)
| # | Action | Command | Status |
|---|--------|---------|--------|
| 1 | Install fwupd | `sudo pacman -S fwupd` | **Done** (fwupd 2.1.1) |
| 2 | Update linux-firmware | `sudo pacman -Syu linux-firmware` | Pending |
| 3 | Check NVIDIA driver version | `pacman -Q nvidia` | Pending |
### Scheduled (Medium Risk - Requires Maintenance Window)
| # | Action | Risk | Downtime |
|---|--------|------|----------|
| 4 | ~~Update NVMe firmware to GXA7801Q~~ | ~~Medium (power loss risk)~~ | **Applied 2026-04-02, reboot pending** |
### No Action Needed
| Component | Reason |
|-----------|--------|
| Motherboard BIOS | Already at latest (F53) |
| SATA SSD | EOL, no updates available |
| GPU VBIOS | EOL, no updates available |
| CPU Microcode | Managed via kernel/firmware |
| NIC Firmware | Managed via kernel/firmware |
| USB Peripherals | No update mechanisms |
---
## Risk Assessment
### NVMe Firmware Update (GXA7401Q -> GXA7801Q) - APPLIED 2026-04-02
| Risk | Mitigation |
|------|------------|
| Power loss during update = bricked drive | Use UPS, verify battery backup |
| Data corruption | Backup critical data first |
| Incompatibility | Verify model match (MZVL2512HCJQ-00B00) |
### General Considerations
- **Production workstation**: All firmware updates should be scheduled during non-critical hours.
- **Rollback**: BIOS has dual-BIOS; NVMe/SATA have no rollback mechanism.
- **Testing**: After any firmware update, run `smartctl -a` and `nvme smart-log` to verify health.

## Firmware Update Applied
> **Date**: 2026-04-02 10:51 CET
### Key Discovery: Firmware Naming Convention
| Suffix | Type | Model Suffix |
|--------|------|-------------|
| `GXA***1Q` | Non-SED | `00B00` (our drive) |
| `GXA***2Q` | SED | `00B07` |
Our drive (MZVL2512HCJQ-**00B00**) requires `GXA7801Q`, NOT `GXA7802Q`.
The OVH mirror only hosts `GXA7802Q` (SED variant) which was rejected as "Invalid Firmware Image".
### Correct Firmware Source
- **Repository**: `lolyinseo/samsung-nvme-firmware` (GitHub, 199 stars)
- **File**: `PM9A1/ASUS/GXA7801Q/GXA7801Q_20221102.bin`
- **Size**: 2,097,152 bytes (2.0 MiB)
- **SHA256**: `76ad2b0c35581cb71bd4c5a5fd358a15c4432aa38e9e983acc2349d2b24b5a11`
### Update Process (all succeeded)
```bash
# Step 1: Download to controller SRAM
sudo nvme fw-download --fw=/tmp/GXA7801Q.bin /dev/nvme0n1
# → Firmware download success
# Step 2: Install to slot 2 (preserve original in slot 1)
sudo nvme fw-commit -s 2 -a 0 /dev/nvme0
# → Success committing firmware action:0 slot:2
# Step 3: Activate slot 2
sudo nvme fw-commit -s 2 -a 2 /dev/nvme0
# → Success committing firmware action:2 slot:2
# Step 4: Reboot to apply
sudo reboot
```
## Next Steps
- [ ] Reboot system to activate GXA7801Q firmware
- [ ] Verify firmware version with `nvme list`
- [ ] Re-run identical benchmarks post-update
- [ ] Compare results in `docs/tech/nvme-benchmark-post-gxa7801q.md`
