HP Omen 35l CPU compatibility

Can the hp omen 35l use the AMD 8700F or the 8400F

@Javier58,

Welcome to our HP Community forum!

Your HP OMEN 35L Gaming Desktop GT16-0xxx as fitted with the Wolant motherboard (SSID: 8CF4) is not compatible with the Ryzen 7 8700F or Ryzen 5 8400F -at least not without a BIOS update from HP, and as of now, HP does not officially support these CPUs.

Here's a breakdown of why:

---

1. CPU Architecture Compatibility:

All three CPUs (8700G, 8700F, 8400F) are based on the Zen 4 architecture and use the AM5 socket. So, physically and electrically, they're similar.

However:

• OEM motherboards like HP's Wolant (SSID: 8CF4) often have strict CPU support lists, and only support CPUs explicitly validated by HP.

• The Ryzen 7 8700F and Ryzen 5 8400F are recent additions to AMD's lineup, introduced in 2024, and lack integrated graphics (iGPU), unlike the 8700G.

---

2. HP BIOS Limitations:

HP does not provide user-accessible BIOS microcode updates to support newer CPUs outside of what the system shipped with or what HP has tested.

As of now:

• The Wolant motherboard BIOS is tailored for G-series Ryzen 8000 APUs, such as the 8700G and 8600G.

• There is no public indication that HP has added support for non-G CPUs like the 8700F or 8400F.

---

3. No iGPU = Potential Problem:

Since the 8700F and 8400F lack integrated graphics, they require a discrete GPU to display anything.

• If HP’s BIOS/firmware expects an APU with integrated graphics, a CPU-only chip may cause POST failure or black screen, even with a dedicated GPU installed.

---

Conclusion:

Not recommended to swap in a Ryzen 7 8700F or Ryzen 5 8400F into the HP OMEN 35L GT16-0xxx with the Wolant 8CF4 motherboard unless:

• HP explicitly updates the BIOS to support them (unlikely based on HP’s historical practices).

• Or, a BIOS mod is used (which voids warranty and is risky on OEM systems).

---

Alternatives:

For now, stick with officially supported Ryzen 8000G APUs, such as:

• Ryzen 7 8700G

• Ryzen 5 8600G
