Wanting to enable Resizable BAR

[Lakridsen]

Hello, I would like to enable resizable bar on my pc. But when I enter the BIOS, the setting is not there, let alone the advanced settings. My specs is able to support it so i just need to change the setting. Is there any way what so ever to change the setting to enabled?

Thanks in advance.

@Lakridsen,

Welcome to our HP Community forum!

Enabling Resizable BAR on your OMEN 30L Desktop PC GT13-1000i can enhance performance by allowing the CPU to access more GPU memory. However, accessing this feature involves several considerations:

1. BIOS Access and Settings: HP's BIOS interface is often streamlined, limiting advanced configurations like Resizable BAR.

Unfortunately, Users have noted the absence of such settings in the BIOS menu.

2. Hardware Compatibility: While your system's hardware may support Resizable BAR, enabling it requires:

• Compatible CPU and GPU: Ensure both support Resizable BAR.
• Updated VBIOS for GPU: Graphics cards need firmware that supports Resizable BAR.
• Motherboard Support: The motherboard's firmware must accommodate this feature.

3. Firmware and BIOS Updates: HP has released VBIOS updates for certain GPU models to support Resizable BAR. However, these updates are model-specific.

Recommendations:

• Check for Updates: Visit HP's support page to see if there's a BIOS or VBIOS update for your specific model that enables Resizable BAR, or at least see if you got the latest BIOS update, such as Version: F.23 Rev.A (Jan 13, 2025) assuming your PC is fitted with the HP OasisOC motherboard with SSID: 886C.
• Contact Support: If updates aren't available, reaching out to HP Support can provide clarity on future updates or alternative solutions.

Please exercise Xtreme caution with any third-party firmware "solutions", as they can lead to system instability or warranty issues.

Kind Regards,

Hello,

I have OMEN 30L Desktop PC GT13-1000i

GPU: RTX3080

CPU: i7 11700F

Mobo: HP 886B 

All other requirements are checked except Resizable BAR is not enabled in BIOS and I can't access advanced BIOS settings.

Motherboard is BIOS is updated to F.19 Rev.A released January 13. 2025

Do I really need to buy new motherboard to enable this setting because advanced BIOS settings are locked/hidden?

@Romppa,

Like I mentioned in my first post in this discussion thread, quote: "Unfortunately, Users have noted the absence of such settings in the BIOS menu."

If the Resizable Bar feature is what you are looking for, the stock HP OMEN motherboard isn't going to work for you.
