Performing overclocking with a fixed CPU inside a laptop
Performing overclocking with a fixed CPU inside a laptop
Hi, I'm using an HP ProBook 6570b with an Intel Core i5 3210M processor. I can't access overclocking settings via the BIOS and haven't found any good software that lets me adjust the multiplier of a locked processor. I'm wondering if there are other ways to overclock, like programs that modify BIOS or FSB?
P.S. I'm not here to talk about the risks since I'm fully aware of them. This old laptop is fine, and I think the performance boost is worth any possible damage.
The 3210M has a locked multiplier, meaning no software can unlock it. Raising the FSB/BCLK might help slightly, but only by a few percent at most. It’s unlikely to be effective and may not justify the effort. If the chip is in a socket (FCPGA988) and not mounted to the motherboard (FCBGA1023), consider looking for a Core i7 replacement on EBay.
The only program I’m familiar with that’s widely used for laptops is ThrottleStop.
Your laptop is likely
fixed from the start. I wasn’t able to speed up my friend’s gaming machine either. Changing the BIOS settings on a laptop is the simplest method to render it unusable.
My main concern is the temperature. Increasing the clock speed raises heat production. Once it hits 95°C, the CPU begins thermal throttling to reduce temperature. This would make the overclock unnecessary by lowering the clock speed.
The 3210M has a locked multiplier, meaning no software can unlock it. Adjusting FSB or BCLK may only provide a small improvement. It's unlikely to be effective and may not justify the effort. If you find a way to raise the clock speeds, it will likely only offer a slight gain.
