I have a Pentium D 915 (2.8 GHz, 2x2MB L2 cache, 800MHz FSB). Would the 800->1066 mod work for this processor? My VID is 1.2250.

The vmod you get with the vmod calculator will work, I'm certain that there exist bsel mod's for the old Pentium 4 series, but I'm certain if it is the same as on those after core 2 duo came. Search the net for Bsel an Pentium4 and you will find it

(I posted this on the Intel board, but did not get a reply. Then I saw this sticky.)

Hello:

I am a new poster with no previous OC experience. I have built one PC and replaced and swapped parts on a bunch of others.

I work at firm that runs AutoCAD (drafting and design software) and we recently purchased five Dell computers with E7400 processors. It is my understanding that Dell MBs generally cannot be OC'd using voltage mods because of a limited bios. I would probably not be interested in the complexities of doing that anyway. What intrigues me is the possibility of what appears to be a simple mod to the pins as shown at the beginning of this sticky.

My question is whether this mod would be a good or bad idea for someone with no OC experience? Is this relatively foolproof? What is the performance increase from 2.8? Would I need to upgrade from the stock air cooling fan? I would definitely start with just one of the boxes and, if successful, move on to the others.

I would appreciate any and all opinions on this and thank you in advance for your comments. Thanks.

I have had read and can't seam to find if anyone has posted a vid mod for a Q6600 G0 my current core voltage is 1.2. Was wondering if theres a mod for this befor I do the 1333 bsel mod?

It is the same BSEL mod for all Q6600, the most easy BSEL mod is from 1333Mhz to 1600Mhz, to do that mod you only need a 1x1mm small piece of insulating tape to do it

civilsurvey:
Doing 1066 --> 1333FSB will give you 3163.5Mhz and you will "feel" the diffrense, you need no experience at all becuase this really isen't overclokking, you dosen't need to mix your own BIOS and it is really easy, try it out, if it dosen't work good for you just remove the mod, you can't kill the hardware this way and you dosen't loose your warrenty.

Sorry my bad english, but it get to this point after a little to much beers

civilsurvey, the 7400 has a 1066 fsb, with a bsel mod it would be possible to take it to 1333. Depends on whether the motherboard supports this.

Hello,

I have a Dell Vostro 200 which has a foxxconn G33 Intel MB.
I was able to successfully perform the FSB mod on my E4300 CPU to go from 1.8ghz to 3.0ghz . I was wondering however if someone could point out where i might be going wrong with the VID mod. I believe ive done it correctly but the vcore didnt change, it stayed at 1.325.

I have attached 2 images, a whole chip view and a close up of the VID mod.

TIA

hi,
does anyone know of a bsel for a 478 celly. its a 2.8ghz and its just asking to be overclocked. but its in a board that wont allow OCing. If someone can find a bsel for it that would be great. Thanks

You did the VID mod on the wrong end. With the way it's oriented in the picture you need to connect the pins in the top left rather than top right.
