Is it possible to increase the CPU's bus speed to 125 using a CPU strap?
Is it possible to increase the CPU's bus speed to 125 using a CPU strap?
Hello,
I am eager to push my system over its limits and I truly think the components can handle it.
Here’s what I have installed:
Mobo: asus p9x79
CPU: i7 3820 (currently at OC of 4.3 gh)
Ram: Corsair CMX16GX3M2A1600C11, 16gb 1600mh 1.5v (2x8)
GPU: 1060 3gb
Pws: Corsair Cx750, the older model is 80 Plus Bronze
Cooler: Corsair H80 watercooler
I’ve previously overclocked with the max multiplayer setting and achieved a speed of 43. It remains stable at 1.25 volts, reaching a peak temperature of 57°C under load.
Now I aim to further boost performance using the CPU strap.
I plan to adjust it to 1.25x, setting the black to 125 while keeping the host clock at 100 MHz. Then I’ll switch the RAM multiplier to 13.33, which should push the speed to around 1666 MHz.
Please confirm if any of my suggestions are incorrect.
Everything is similar to this guide except for the RAM configuration.
Before proceeding, I wanted to check the community about whether a 105 bclk is the upper limit.
Thanks for reading, and I look forward to your feedback.
No, you can't simply raise the strap (FSB) to 125MHz. You might need to navigate a more complex menu, but there should be an option to boost above 100MHz in 1MHz steps. Be careful, though—this could risk damaging your components. It's no longer common to achieve such high FSB speeds, and you'll likely only get around 3-4MHz on the bus, especially if you've already pushed the CPU limits.
Multiplayer is a form of game ROFL 😂 it's multiplier or just the ratio. You might attempt it but likely face a black screen; clearing CMOS will help.
Lol, my muscle memory kicked in. Would I see a black screen due to the board lagging? And would clearing the CMOS reset my settings? I’ll look it up a bit more, thanks.
When you attempt to overclock just to get the system to start up, it doesn’t guarantee stability. This is because you are pushing the silicon beyond the boundaries that the manufacturer has confirmed can run at 100% stability across most systems without additional checks. Before proceeding, avoid making significant adjustments. While it may seem logical to adopt settings found in other systems, simply having those options available does not ensure your hardware will perform reliably. Moderate overclocking often leads to instability and may require resetting the BIOS. Extreme overclocking can cause permanent damage. Review the frequently asked questions before making changes and learn how to properly configure the processor, including base clock, multiplier, and core voltage. As a tip, if you must reduce the base clock, it’s unlikely to improve real-world performance, even if the numbers suggest otherwise.
Thank you for your message. I've reviewed your query and provided my response. You're asking about adjusting the work increment while using a CPU strap overclock, noting the lack of options between 100 and 125 and whether changing it would be beneficial. Your experience of saving 90% is noted.
No, you can't simply raise the strap (FSB) to 125MHz. You might need to navigate a more complex menu, but there should be an option to boost above 100MHz in 1MHz steps. Be careful, though—this information is important because you risk harming your components. It's no longer easy to achieve a significant FSB jump like before; most systems now cap at around 3-4MHz unless you've already pushed the CPU limits.
The issue with that CPU generation involves a reference clock linked to the PCI clock, which also affects other clocks. Some devices struggle with PCI overclocking, and your graphics and storage may react poorly. The Intel management engine might also block booting.
