Back when overclocking meant pushing real hardware instead of sliding fancy software sliders, SetFSB was the go-to tool for squeezing extra performance out of your CPU — right from Windows.
The idea behind it is simple but bold: instead of changing your clock speeds in BIOS, SetFSB talks directly to the motherboard’s clock generator (PLL chip) and adjusts the Front Side Bus (FSB) frequency on the fly.
That means you can tweak your CPU and memory speeds live — no reboot, no BIOS menus, just instant changes.
It’s old-school and a little risky, but for hardware tinkerers, that’s part of the charm.
If you’ve ever owned an ASRock motherboard and wondered what that little “Turbo” utility actually does, you’ve probably seen S3TurboTool.
It’s one of those small companion apps that never makes big headlines but ends up being genuinely useful if you know what to do with it.
S3TurboTool was built by ASRock as a lightweight Windows utility for adjusting memory timings, frequencies, and voltages without rebooting into BIOS.
In simple terms — it lets you fine-tune your RAM performance in real time.
No need to keep bouncing between Windows and UEFI every time you change tRCD or tRFC.
It’s fast, minimal, and very much a “power user” utility. You either love it or you never open it again.
If you like keeping an eye on what your processor is really doing — not just “CPU usage 50%” but the details that actually matter — Quick CPU is the kind of tool you’ll appreciate.
It’s small, light, and surprisingly deep once you start digging into its menus.
The app shows every little thing your CPU is up to: core temperatures, boost frequencies, power states, and voltage curves. You can tweak CPU parking, C-states, boost behavior, or thermal limits — all from one clean window.
For laptop users, it’s great for taming heat and noise. For desktop tinkerers, it’s a playground for squeezing out that last bit of performance.
It feels like the software equivalent of lifting your car’s hood — no gimmicks, just real stats and control.
If you’ve ever dug into BIOS modding or tried to rebuild an AMI firmware image by hand, you’ve definitely come across MMTool.
It’s one of those utilities that doesn’t look like much — just a tiny window, a few buttons, and some cryptic tabs — but it’s been part of every serious BIOS technician’s toolbox for years.
MMTool (short for Modular Management Tool) was developed by American Megatrends (AMI) as an internal utility for editing and rebuilding BIOS modules.
Somehow it leaked into the wild ages ago and became a kind of quiet legend among firmware modders.
You use it when you want to replace an OROM, inject a microcode update, or pull apart a UEFI image to see how it’s built.
It’s not friendly, and it’s definitely not meant for beginners — but if you know what you’re doing, it’s surgical.
