Upgrading the gpu

Still not working

@racweay08,

I have done some additional research, and this will get a little wordy -but it will provide you with all the information relevant to your issue.

OK, the problem you are facing is almost certainly platform-level compatibility, not a defective GPU.

There are three Intel Arc–specific requirements that routinely break Arc installs in OEM systems such as your Victus 15L, even when your Nvidia RTX 2060 card worked previously.

Problem #1: Intel Arc requires Resizable BAR (ReBAR) — no exception.

Intel Arc GPUs are architected assuming ReBAR is enabled and functional. Without it:

• The system may POST and show BIOS (as you reported)

• Windows may fail to initialize the GPU

• Drivers may refuse to load or crash silently

This is fundamentally different from your RTX 2060 behavior, which does not require ReBAR.

The key issue:

Most HP Victus 15L BIOS implementations do NOT expose:

• Resizable BAR toggle

• Above 4G Decoding toggle

Even if the hardware could support it, HP often locks these options out.

If ReBAR cannot be enabled, Intel Arc will not work correctly, regardless of PSU, cables, or drivers.

Problem #2: CSM must be fully disabled (pure UEFI + GOP) :

Intel Arc will not operate properly with:

• Legacy Boot

• CSM enabled

• Hybrid boot modes

You are seeing the BIOS screen only tells me:

• The Arc card's GOP firmware is working

• The PCIe link is alive

It does not mean Windows compatibility is satisfied.

On Victus systems:

• Even when Secure Boot is enabled

• CSM may still be implicitly active or non-configurable

If the BIOS does not explicitly support UEFI-only + ReBAR, Arc fails at driver initialization.

Problem #3: Victus 15L firmware limitations (this is the real blocker) :

The Victus TG02 series is notorious for:

• Locked-down BIOS

• No ReBAR toggle

• No Above 4G Decoding

• OEM validation limited to Nvidia / AMD SKUs HP sold with the platform

HP never shipped this model with Intel Arc, and therefore:

• It is not validated

• BIOS support is incomplete

• HP will not provide a fix

This is why:

• RTX 2060 (and other RTX graphics cards) work

• Arc B580 posts but fails in Windows

What you can verify -quick checklist:

Please confirm all of the following:

1. BIOS boot mode = UEFI only

2. Secure Boot = Enabled

3. CSM = Disabled (or not present at all)

4. BIOS shows Above 4G Decoding → if missing, that's the stop sign

5. Latest HP BIOS installed (even then, unlikely to help)

If Above 4G Decoding / ReBAR is not visible, unfortunately, case closed...

Bottom line -the answer you are not looking for:

You are not missing a driver step, CMOS trick, or power detail.

Intel Arc requires platform features that the Victus 15L TG02 BIOS does not expose.

The GPU displaying BIOS but failing in Windows is unfortunately textbook Arc-on-OEM behavior.

Practical outcomes:

• Nvidia RTX 2060 → works

• AMD RX 6000/7000 → likely works

• Intel Arc → not compatible with this platform

Recommendation:

• Return or resell the Arc B580

• Use a Nvidia or AMD GPU instead

• Or move the Arc card to a retail (gaming) motherboard with confirmed ReBAR support

This is a firmware policy limitation, not user error. Anyway, I really want(ed) this Intel card to work for you -I refrained from sounding negative.

Kind Regards,

Okay that's stupid but thanks for the help

@racweay08,

With a 500-watt power supply, for a meaningful upgrade from an RTX 2060, you can upgrade to a smaller-sized (dual fan) RTX 4060 or an RTX 4060 Ti (such as this one), models powered by a single 8-pin PCIe power cable.

There was some uncertainty whether or not the latest Nvidia RTX 50xx cards were compatible with the HP 15L Gaming Desktop TG02-0xxx platform, but recent information suggest that they are, in fact compatible as well.

In that case, I would recommend a smaller-sized (dual fan) RTX 5060 Ti or an RTX 5060, such as this model, which sells for under $300 via Amazon.  The RTX 5060 outperforms the Arc B580 by a wide margin.

Best wishes,
