Yeah, I gave up on this only because Dell ended up CompleteCaring me another replacement that had a Merom in it already. Nonetheless, I would have been very hard pressed to be clipping a pin off of a processor that was still under warranty Good work though, you may have found the missing link for this to work at 100%. I tried what you did, by isolating the pin and then using a jumper for the socket, but that was just too much stuff to be jamming into the little hole in the zif socket

I don't mind removing a pin from a relatively inexpensive cpu like these yonah T20X0s (less than $100 on ebay). If it was a $500 merom T7600, that would be another matter. The problem with insulating the pin with a piece of wire insulation is that its very difficult to get that insulation out of the socket if you want to go back. If that thing plugs the hole permanently you will not be able to upgrade or swap another cpu later. Also, as you mentioned it will not work for this type of pin mod because the insulation prevents the wire bridge from making contact inside the socket. To me the cpu is more expendable than possibly damaging the socket (and therefore the whole mainboard) with insulation. I was surprised that it worked because in the old BX and even later intel chipsets the cpu socket pins were pulled up H on the board itself. So if a signal pin was missing or insulated, the pin was pulled H by a pull-up resistor. It looks like these new laptop chipsets are using an active H from the cpu itself. So if a pin is missing or insulated ("floating") the chipset probably sees is as a L or invalid state. That might explain why the multiplier x6 was locked in the other guys case. MaxFSB

Sweet! Now we have to see if this works on Meroms in 800 MHz Santa Rosa mobos

You can't put a 667mhz Merom into a Crestline motherboard, they have different sockets.

I will try to only jumper the two pins as fast as my gf lets me near her 9400. IF that doesn't work, what will the status of the CPU if I rip of the pin. Can I use it at standard speeds?

today i pinmodded my 1.6 ghz yonah, but laptop not booting, i think it's because of the rams, they are pc 4200 spec . i must try with faster rams.

i figured out , clock generator of my i945GM chipset is
ics 954305lklf 500801 INDO 0550

with 14.318 crystal.

when i push power, it restarts 2-3 times, no video.

BSEL[1] is a L from the cpu, L-L-H = 533. So if you only jumper BSEL[0] to BSEL[1] without removing the BSEL[1] pin from the cpu, instead of L-H-H = 667, you wll actually be pulling BSEL[0] L, resulting in L-L-L. That is an invalid FSB so the chipset will not allow the cpu to boot. You have to rip the BSEL[1] pin AND jumper BSEL[0] to BSEL[1] to get L-H-H = 667. If you rip the pin but your jumper does not make good contact inside the socket you will get L-X-H where X is floating state. The chipset will probably read it as a L-L-H anyway and you will still be at 533. Basically ripping the pin is safe and should not cause the cpu to fail to boot, even without a jumper. Also, make sure you have PC-5300 667 memory after the pin mod or you might not boot since most laptop sodimm PC-4200 will not run at 333 which the chipset will be calling for after the pin mod.

Yes, it sounds like you need the PC-5300 667 rams. See my above reply to hifiking. The fact that it tries to boot 2-3 times but fails may actually be a good sign that you have a successful pin mod but the PC-4200 rams are not liking trying to run at 333. MaxFSB

Today i tried with pc-5300, result NO BOOT, NO GO. and reverted to original. Not working on my HP Pavillion DV2015ea , 1.6 yonah 945GM

Doh! I thought I had some 5300 memory around, but no.

That was too bad.

So you can clip the pin, and if the pin mod doesn't work, you can still run the processor at original speed, nitehawk?

If you are running PC-4200 533 memory, shoudln't a memory divider kick in if you are running PC-4200 533 memory with the CPU at 667Mhz FSB?

In fact, most laptops sold with the 667Mhz FSB Core 2's come with PC-4200 memory. (i.e., it is a $50 upgrade on the Dell inspirons to go to PC-5300)

Ok so I have a 1.4 cel in my unit now with 2gigs of 4200 memory. I got a core duo 2.16 from a friend really cheap, but after dropping it into the machine it powers up with a blank screen? The unit is an HP v5000 more spacifically a V5204NR(the V5000 shows an AMD setup which mine is not) so if my FSB on this machine is limited to 533 then what pins should I set on this 667 CPU to force it to 533? I'm not sure if the BIOS is locking out this CPU or if it is a speed issue, as I have heard that on low end machines with 945GM chips some manufactures cut the 667 capabilities in BIOS, which leaves 333, and 533.

Also since I am an old elctronic tech from yester years, it sounds that the CPU puts the highs and lows on the BSEL's sockets to get what speed it wants, so in essance if you rip off all the CPU's BSEL pins and then use the VCC and VSS pins adjacent to the BSEL socket's then you could make it easier to jumper without the worry of making another BSEL go high instead of low.

Well, I tried this now with a T2050. Isolated BSEL1 and jumped BSEL1 and BSEL0.

667FSB, but stuck at 6x, tried all several insulation methods and many jumpers. No good.

Then I took everything out (back to normal), and still 667FSB and 6x. So now I am stuck with a T2050 at 998mhz what so ever. No app can change that 6x to 12x. Whats wrong?

I succesfully pinmodded a Pentium Dual Core 2080 (1.73GHz @ 2.16Ghz) as well - when I have time I will throw a few screenshots / benchmarks up, and hopefully a picture walkthrough as well.

I would warn anyone trying to do this mod with a Core Duo based CPU - (2050, 2350, etc) So far two people have done this with a result of being stuck at the 6x multiplier. Remember, the 2080 is based off the Core 2 Duo's, albeit with 1MB L2 cache, so the 6x lock might not be present.

Hifiking, just wait a while. If you stuffed the socket with more than just the pin that belongs in there (i.e. the IDE cable insulation I used) it will take a bit for the contact point in the socket to get back to normal. Run SuperPI for a few cycles and get the CPU hot, then reboot.

Well, still no good. Isolating the BSEL1, what does that do? And jumping BSEL0-1, what does that do?
