Why your second GPU runs at x4: reading PCIe lanes and BIOS settings with a free scan

A free Windows scan that reads your hardware and BIOS and tells you what to change, for PC owners and IT fleets.

You paid for a fast GPU and fast memory. Then you notice the card reports x8 or x4 instead of x16, the RAM runs at its safe default speed, and virtualization is switched off. Nothing is broken. The machine simply never got set up. Most PCs run on factory defaults, and finding the right menu on your specific board means a forum search and some guessing.

BIOS Advisor is our attempt to turn that guesswork into a two-minute scan and a plain-English plan.

What is BIOS Advisor?

BIOS Advisor is, in its own words, "the AI firmware advisor." A small Windows agent reads your hardware and BIOS, then an AI review tells you what to change, where in the menus, and why. A web dashboard holds the results. It is a product of LIKE A KING INC., a small New York software studio.

What problem does it solve?

Three things show up repeatedly: memory running below its rated speed, a GPU sitting in the wrong slot or on shared lanes, and useful features such as virtualization left off. Fixing them requires knowing how your motherboard is wired and where your maker hides each setting. BIOS Advisor reads that information from the machine and explains it for your goal, such as gaming, local AI, creator work or a home server.

How does it work?

The flow has four steps: scan, understand, fix, prove.

Scan. The agent runs read-only, takes about two minutes, and collects board, BIOS, memory per slot, every PCIe card and the lanes behind it, drives, peripherals and security state.

Understand. The AI review explains each finding with the exact menu path on your board.

Fix. On Dell, HP and Lenovo business machines, it can apply the change through the maker's own settings interface and restart. On every other board it walks you through the change and you make it yourself.

Prove. The next scan checks that the change took.

The part we find most useful is what the site calls slot intelligence. Two slots can look identical and behave very differently. The scanner reads whether each card is wired to the CPU or the chipset and how many lanes it really gets. The example on the site: your GPU has the best slot, x16 straight from the CPU. A second GPU in the second x16 slot splits it to x8/x8, while the third slot keeps the main card at x16 but gives the new card x4. It also flags a GPU running x8 or x4 because of a slot choice or a bad seat, and shows which drives, network cards and slots share the chipset link.

Safety design. Changes are limited to an allow-list. It excludes overclocking, voltages and anything that turns security off. BitLocker is suspended for exactly one restart when needed. It does not update your BIOS: it tells you when yours is old and links the download page on your board maker's site.

Where your data goes. The scan holds hardware details only: no serial numbers, MAC addresses, product keys or user names. By default the AI review runs on a local model. If you choose a cloud provider in settings, the scan is sent to that provider for each review.

Who is it for?

Enthusiasts who want the hardware they paid for to run as intended, people planning a second GPU, and local-AI users who care about lane and memory layout. There is also a Business side: firmware baselines for fleets of Dell, HP and Lenovo machines, covering Secure Boot, TPM, boot order, wake-on-LAN and power-loss behavior, with a log of every scan, plan, approval and result.

How much does it cost?

The scan is free. Paid licenses are one-time payments in USD, with no subscriptions:

• Personal: $25 once, for up to three machines with full reviews and fixes.
• Pro: $49 once, for unlimited machines and servers.

Checkout runs through Stripe. These are digital licenses and all sales are final, so try the free scan first. Fleet pricing is by conversation via the Business section.

How is it different from the obvious alternatives?

Manufacturer tools and manuals are authoritative for one brand and one board, but you have to know what to look for. Hardware monitors and diagnostic utilities show you sensor readings and specs, but typically leave the interpretation to you. Forums and review channels hold great knowledge, though it is scattered and rarely tied to your exact board. BIOS Advisor combines the scan, the board-specific explanation and, on three brands, the change itself. We also link independent hardware creators on the site and say plainly that we are not affiliated with them.

What it can't do yet

• One-click auto-fix works on Dell, HP and Lenovo business machines only. Servers over Redfish and a Mac security review are on the roadmap.
• It scans Windows 10 and 11. Linux and macOS are "next".
• The agent installer is new and unsigned, so Windows may say it "protected your PC". The site says to choose More info, then Run anyway. It also states the agent is read-only and changes nothing without approval.
• All sales are final on paid licenses.

What's next?

Linux and macOS support, Redfish for servers, a Mac security review and more verified board data. Sponsors can fund verification of a board family, and a one-time contribution option ($5 to $50) funds new boards and the extra platforms. The site states the advice itself is never for sale.

The business behind it

The market is the installed base of Windows PCs that ship and stay on defaults, from gaming rigs to office fleets. Revenue has three stated lines: one-time Personal and Pro licenses, Business fleet baselines for Dell, HP and Lenovo, and sponsor and partner programs for verified board data and white-label scan reports. Distribution starts with the free scan, which is the product's own demo. The defensible piece, as we see it, is accumulated, verified per-board knowledge: slot wiring, menu paths and safe settings. That is a plan, and we are not quoting user counts or revenue because we have none verified to share.

FAQ

Can it break my PC?

It is read-only until you approve a plan. Automatic changes happen only on Dell, HP and Lenovo, through the makers' own interfaces, with an allow-list.

Does my data leave my computer?

The scan holds hardware details only. The AI review runs locally by default.

Which machines can it scan?

Any Windows 10 or 11 PC.

Will it update my BIOS?

No. It links the exact download page on your board maker's site.

Is Personal really one payment?

Yes, $25 once for up to three machines. Pro is $49 once.
