    OK... I didnt create this mod, and I just found out about it.... so if you have heard about it, please forgive me.

    Anyhow, this mod will make your 1066 FSB Conroe CPU run @ 1333 FSB STOCK!

    I have seen this work on the Core Duo's and the Quads.

    I also read someone took their 800 FSB e4300 boot @ 1066 FSB STOCK doing the same MOD!..... any how here ya go!

    Another Walkthrough using e4300

    Another One

    This is showing the bottom of the CPU as if you had it upside down, facing you.

    Original Post.

    got bored tonight and was looking around at VR forums and came across a old pic Shamino posted awhile back and thought... why not give it a shot...

    so I took one of my spare conroes, and got my conductive ink pen, did the mod, let it dry, took my PC apart and popped this in... and it almost worked.

    it booted at 1333, then I rebooted, and it went back to 1066... and was jumping back and forth.
    so I took the CPU out, and saw, I didnt have a nice clean connection between the two BSEL pads... so I traced over it again, and let it dry, blah blah blah...

    10 minutes later... it works.
    now, it's working just fine.

    boots up everytime at 7 x 333.

    no big deal really since I know this CPU can do over 590, but its still fun to have a higher default FSB for the hell of it.

    I wanted to see if this works, so I could try it on my quad core CPU...
    hoping theres a slim chance in hell, that if it boots at 1333, the chipset strap will be looser, and give me some extra OC room.
    thats a 1-100 shot... but if I never do it, how can I say it wont work??

    atleast this one worked.

    what would be kinda interesting, is if you took a E4300, and did this mod to it, assuming you knew the CPU could do 3 ghz, it would boot up at 9 x 333 for 3 ghz.
    that would be pretty cool for those cheap boards that been coming out at Frys and such, with the CPU.

    anyways, next try is to make my Quad Core do the same thing...
    not really holding my breath on it, but its worth a shot.

    heres the boot up speed I got from CPUZ after the mod.

    http://valid.x86-secret.com/show_oc?id=165085

    total down time, about 20-30 minutes, to take it apart, do the mod, let it dry and put it back together.

    last note...
    before doing this kinda mod, make sure you have a bios on your board that will allow a 1333 FSB CPU to be used in that board.

    can anyone tell me why this 'works' and if there is proof of it actually increasing performance? perhaps this mod just tricks the mobo into thinking its running 1333...

    would it even be worth a pentium D user to do this if it works?

    edit: if i did this and it didn't work, what would happen to the cpu? would it fry or just not boot?

    I would imagine that all you would have to do is break the connection and it would go back...

    Also someone else with an 800FSB did this and it went to 1066

    yeah... the famous pin mod. Anyway for the E4500 due to its 11 multi... 266 FSB and a higher voltage = SWEEET

    lol, I'm kind of curious as to why this would work... but not enough to post about it.

    what I want to know, is who came up with this, and why did they decide to randomly start connecting things on their processor?

    1333 isnt much gain is it?
    I read that it was like 2% overall gain...peanuts unless your going for WR.
