|The mod (BSEL),|
Here is what I read about it.
BSEL & VID Mod Guide
This mod applies to most, if not all, Intel socket 775 CPU’s that use a 800MHz or 1066MHz FSB.
What is a BSEL mod?
A BSEL mod allows a CPU to be run at a higher speed via hardware modification, without changing any settings in software (Either the BIOS or via software such as SetFSB). Most motherboards (See notes for more about this) use voltage/ground from the pins on a CPU to determine the CPU’s FSB. The idea of a BSEL mod is to physically connect pins on a CPU, to make the motherboard ‘think’ that the CPU has a higher FSB than it actually does.
For example, the Intel Pentium Dual Core E2160 CPU (1.8GHz) has an FSB at 800MHz, a bus speed of 200MHz and a multiplier of 9 to give the CPU its speed of 1.8GHz (200 x 9). Now, if the pins on the CPU are connected like a CPU with a FSB of 1066MHz, the bus speed would now be 266MHz, and the CPU would now run at 2.4GHz (266 x 9).
Why would I need to do this?
If you’re motherboard can overclock your CPU from the BIOS, you probably don’t need a BSEL mod. However, for motherboards that have no overclocking settings, like OEM motherboards, this is a simple method of overclocking a CPU. Alternatively, if your motherboard’s BIOS has difficulty overclocking, the mod is a simple way to increase the CPU speed.
How do I do the mod?
To connect the pins on the CPU you will need:
Conductive ink pen or copper tape
Connecting the pins:
Refer to the diagrams in this guide to make sure you’re connecting the right pins. Then, mask the pins you aren’t connecting with electrical tape, this isn’t 100% necessary but makes the job of connecting pins much easier. Connect the desired pins using the conductive ink pen, go grab a drink and a sandvich, and by the time you get back the ink should have dried.
BSEL mod diagrams
The VID mod is similar to the BSEL mod, but instead of increase the CPU’s frequency, it increases the voltage; it is done in the same way as the BSEL mod.
VID mod diagrams (GREEN = COVER)
• This is still an overclock, so it would be wise to stress test using Orthos, Prime95 Etc.
• To reverse the mod, simple remove the pin connections.
• It may be necessary to reset the BIOS to apply the mod.
• Intel Speedstep still works with the mod applied.
• Some motherboards use the CPUID to calculate the CPU FSB and not the pins, this mod WILL NOT work on these motherboards.
