How to update the VBIO on HP Victus 15
How to update the VBIO on HP Victus 15
Hey there! I’ve got a few updates on my setup. I’m running a 15th-gen spec with Ryzen 5 5600H, an RX 6500 XT, 16GB DDR4 3200MHz (dual channel), and a 512GB NVMe Gen4 SSD that copies slowly. HP’s support has been unreliable lately, so I ended up getting it from someone who gifted it to me.
The real issue is performance. Every couple of seconds it stutters—especially during gaming. My FPS drops from 90 to around 80, then spikes back to normal for a few seconds before dropping again. It only happens in games, not in everyday tasks like video editing. I’ve tried disabling several programs (MPO, DXNavi, virtualization, etc.), but nothing helps. The thermal throttling keeps coming up, and the GPU seems to draw more power than the motherboard can handle, dropping to 400MHz.
I checked the logs with hwinfo and found the reason is POWER usage. It looks like the GPU or maybe the dedicated graphics card is overloading. I’ve tried using higher power tools to flash a custom VBIOS, but after rebooting, the system crashes with a blue screen. Now I’m stuck in safe mode, and even after deleting the BIOS, it still won’t start properly.
I’ve been using UXTU’s balanced profile, but the lag persists in-game. Sometimes it fixes itself, but not always. My thermal paste is gone, so I’m wondering if bending the heatsink a bit could help contact better. My factory paste is ruined.
I’d really appreciate any advice or suggestions—maybe someone can help me find a more reliable solution for a budget-friendly fix that lasts. Thanks!
Welcome to the forums! I'm not entirely sure I'm grasping everything, but if you're attempting to flash a new vBIOS, you'll first need a working vBIOS compatible with your laptop's GPU. Then, using AtiFlash, you'll have to write that binary into the chip. This process is delicate and can easily go wrong for no clear reason—so keep this in mind: it's a high-risk step. Regarding thermals, I don't know if you've completed the full maintenance routine—removing the cooling solution, cleaning everything, repasting the CPU and GPU, reapplying VRMs and vRAM chips, and reassembling—if you haven't done it, do it. It makes a big difference. Make sure the cooling fins are clear. If you're planning to modify power delivery to mainboard components, better avoid doing it yourself; it could cause damage.
I’m planning a refresh soon. The thermal paste I received from HP expired quickly, so I’m updating my setup. My CPU runs between 85 to 80°C and the GPU between 83 to 79°C. The room temperature is already around 44 to 45°C. According to what I saw, the issue isn’t with my RX 6500 XT but with the IGPU. It was opened in hwinfo sensors mode, and it’s throttling due to power limits. I thought it was just throttling from the CPU, but it’s actually this small component that’s causing the problem. I can fix it using Afterburner, as HP left the Vega GPU unlocked. See the video linked for more details. This IGPU file (20250414_170546.mp4) confirms it.
