1333 ==> 1600 FSB BSEL Mod

[Changnoi]

I've been reviewing the Core 2 Quad/Extreme data sheets and have an idea for a 1333 ==> 1600 FSB BSEL mod.

The data sheets specifies that:

BSEL2|BSEL1|BSEL0|FSB
-----------------------------------
H | H | L | 400
-----------------------------------
H | L | L | 333

So all you would need to do is change BSEL1 from Low signaling to High signaling.

Now having already successfully performed the 800 ==> 1066 mod which connects BSEL1 to Vss (ground), I think it's safe to assume that the "L"s are grounded.

That's important because it means if I just connect BSEL1 to Vcc or BSEL2, it will ground that other pin instead of changing BSEL1 to Hot.

So what if we completely cover the BSEL1 land with an insulator, and draw some conductive ink to that space from BSEL2, which is already Hot.

The motherboard should detect the same signaling from both lands, thus BSEL2-H, BSEL1-H, BSEL-L, and run at 1600 FSB.

Has anyone tried this? I haven't seen any successful BSEL mods that have done this. Is it because most MBs that support 1600 FSB have good overclocking options or what?

Yes, For a good reason too.
you do realize that if you screw up the grounding you will fry your system?

I admire what you are doing, many people don't bother with this kind of thing anymore.

does your Ram and CPU support The 1600MHZ FSB?

Good Luck 😀

Since most motherboards will overclock to 1600 mhz anyway this mod is really not necessary now if this mod were to unlock the multiplier then it would be something to look into but I doubt there is any pin mod that would do that.
