FSB downclock mod on the intel GL960 and GL40 --- useful info for PLL Modders

Never too late!

Thank you, I am moving but I have an Asus M50Sa I want to throw a T9900 into.

 

Ok, so I need to put T9900 (1066 FSB) in a Dell D630 with A19 BIOS, PM965 Chipset. I udenrstand it would only work with BSEL 800Mhz wire mod, as indicated in the firts post. Trouble is, none of the pictures are visible....and I can't see what exactly do i need to do, nor can I find them them on the net. Everyone talks about it, but since these are usually older threads, all the pics ar eusually espired links. Can anyone help me, please? Pictures with explanations are preferable, as some of these pics arent self-explanatory....like for example i have seen some that do not show the extact socket hole positions in regards to the whole P socket orientation, some show bare wires, some are taped....I am confused...

 

The one I've posted (on the previous page) has the whole socket and a red rectangle on it. That's pretty self-explanatory if you ask me.

 

Thank you, Triturbo, So I understand I ONLY need one wire as indicated by the red rectangle....what is the other jumper for?

Another question, since the T9900 will run at 2.3 Ghz as a result of BSEL downclocking, will it be still faster than T9500 on a 800Mhz system?

 

Lower voltage, but it didn't run smoothly, so I removed it and lowered the voltage through software, although a bit limited.

Nah, probably slower. You are removing the benefit of the faster bus, so clock for clock they would be the same and since the T9500 is running @2.6GHz, you'll be behind some 300MHz. The positive is that you can undervolt it a lot more, since better silicon is used. Then again, the software undervolting is limited, so you might want to give that other wire a go.

 

I see, thanks again...in the light of this, not sure if it is at all worth it...

 

It is worth it if your machine is capable to clock back up. If you can FSB overclock, then you are good to go. Then comes the question how far you can go with the RAM you have.

 

Hello, I am looking to pin mod the motherboard on my dragon pc so it will accept an intel x9100 processor. I have heard a lot of talk about the possibility of clocking down fsb, but the instructions aren't so clear, perhaps because the pictures are no longer available. Can you explain to me how and which pins much be insulated? I plan to use 30 gauge copper wire and regular tape to connect the two socket connections on the motherboard, but I don't know which pins need to be insulated on the cpu.

Please reply soon, thanks!



However you use the word "Isolation" to mean the same as with the original mod on page 1 and the Quad mod you did. This is why I ask for a picture. Did you connect AA7, BR1# to VSS at Y6??

I'm going to try the mod as best I can soon.

I don't think this is off topic for you to post here, as in the 1st post it says "this mod concerns qx9300" [/QUOTE]

 

As I said just a few posts above yours - check the previous page, I have uploaded a picture.

 

Hello, I'm sorry to bump in such an old thread, but I want to share my story. This BSEL mod works on my Sony Vaio. My model is VGN-CR520E (PCG-5L2L): chipset Intel GM965, modded with a P9700, FSB from 1066 -> 800MHZ, then overclocked to 2.4GHZ with setFSB (http://www13.plala.or.jp/setfsb/ , you can tick Ultra for more overclock). Here is the picture of the mod I did:
My Ram also overclocked to ~770MHZ (default is 667MHZ). Hope you enjoy
