Has anyone successfully overclocked p7805u CPU?

Once again i seem to have a locked FSB. It seems one day i can adjust it through Kravis's modified setFSB and the next it no longer works.

If anyone has any advice of what to check i would greatly appreciate it.

I'll start apologizing for resurrecting this post, but I've been spending my nights researching these forums looking for some clues on how to do the TME pinmod on a P-79 mobo and didn't find it.

My CPU is a P8700, and the mobo looks a lot like the P-78, same positioning of processor and northbridge.
It's bottlenecking FPS on most modern games, and I'd like to try the overclocking to see if it helps. Graphics can be lowered, but CPU-related features often can't.. Undervolting has already proven successfull (with a 0.2V/15c drop) which also could be a good sign for overclocking potential.

I haven't opened the notebook yet (prob. gonna do it today) to find out if I'm TME-locked, but I guess it is, seems to be the same for all gateway FXs.

Do any of you know if the same rules of pin modding (to enable SetFSB to increase my 266 bus speed) will apply to my model?
Maybe TANWare can give some insight, for what I read you upgraded your mobo from 78 to 79 right?
And to clarify, if in fact I finally manage to do the modding, is the overclocking reversible? (so I can switch between "factory" FSB values and "overclocked" values using SetFSB without having to remove the soldering)

Thanks for all that you guys already posted.
Even if I dont get any replies from this attempt, it's been a fun read

 

I can not speak for TME modding on these boards other than it has been done. If you unlock the FSB by default it will run at 266 and then you will need a software/bios that can change the default. This means the default is always available.

Yes I changed the boards but both were 266 FSB................

 

Sorry for reviving an old thread. But I cannot find pictures for the pin mod, I've look through the forum 3 times from start to finish and cannot find pictures. They have been deleted by the user apparently. I was hoping someone had them saved because i have the 7805u and would like to breath a little life into it with overclocking. I'm already using Throttlestop but would like to be able to overclock it a little bit further.
Thank you!

 

Yep, I second Baconlover1's request for the images!
If anybody could help us with more details it would be greatly appreciated

Lesterp66, do you still have the pictures you uploaded as a tutorial back on page 17?
Kravis, can you give us any info or pictures regarding the TME pinmod?

I've opened my notebook and took some pictures of my PLL and it's surroundings, but my camera doesn't do well on macro shots.

Maybe someone can give me some insights and/or mark/indicate the correct components to be tinkered with.
When you guys say "pull the resistor", you mean completely removing it from the board? Does that require a soldering iron or can it be done by force only? Which one is it (is it visible on my picture?) ?
Thanks in advance!

EDIT: Ok, I've managed to make it work, the guy from the computer repair shop helped me with the procedure. I'll try to get my hands on a better camera to post some pictures if anyone else still needs them.

 

I would love to have them please! I've been searching all over for a guide / help with it.

 

I'll try to explain it with words while I can't get my hands on a decent macro camera.

First of all, you'll need to be familiar with a multimeter and solder iron, because the points are pretty small (I used a magnifying glass to solder).

The thing is you want to isolate the 11th pin from the rest of the board, and since it has active voltage, you'll want to ground it for safety reasons.

I did that in 2 steps:
1st, I soldered a 10k resistor (I've seen other resistance values around forums, used 10k myself) to the 11th pin and the other end to ground. Since the pin itself is very small, I used the multimeter in "continuity test" to check which other points nearby were equivalent to the pin itself (same node), and used a bigger solder spot that was not the pin itself.
In my case, since the resistor's legs were kinda short, I've used wires to extend it and make it easier to reach the soldering places.

2nd, I disconnected the 11th pin node from the rest of the board. With continuity tests I found out how the circuit continued, and used a knife to scrape the surface of the mobo between the nodes to reveal the electric path. Then used the knife to interrupt the connection, leaving the pin 11's node disconnected from everything else except the 10k resistor.

 

Would you be willing to post a pic of the resistor on the board that pin 11 leads to? I can't figure it out and I've burned up the area around the pin through this whole experiment so I'm having trouble tracing also I don't have any meters
