Re: Looking For ThinkPad T61 4:3 Motherboard
Is there any way I can get mine pre-core 2 Extreme or Quad modded?

The X9000 fits without any mod, just needs Middleton's BIOS (and the discrete fan).
You'll need to search for someone who has done a Quad mod already and ask him/her to do this also for you.

Re: Looking For ThinkPad T61 4:3 Motherboard
Would the X9100 work without any board modification?
Re: Looking For ThinkPad T61 4:3 Motherboard
Nope. This is a 1066 CPU.
This one requires FSB-mod.
X9000 will work straight ahead. It is FSB 800 CPU.

Re: Looking For ThinkPad T61 4:3 Motherboard
It depends on how extreme your view of board modification goes. There is a way to get the X9100 working without extensive motherboard modification, but that would need a very thin piece of wire and a steady hand. The downfall of this particular method is that it does not retain the stock front-side bus speed of 1066MT/s, which gets downgraded to 800MT/s after this mod is applied. Then you would have to manually bring the X9100 to its original clock speed using Throttlestop, since the X9100's clock multiplier is 11.5x (266MHz x 11.5 = 3059MHz to 200MHz x 11.5 = 2300MHz).
If you are not comfortable with dropping a thin piece of wire in the socket and then adjusting it to form a small pin hole to pin hole wire bridge, you should go with a X9000 instead.

How about the core 2 quad, I know how the process goes with it, but how hard is it? How would I retain the original clock? I am willing to do EXTREME board modification!
Also is the core 2 quad stable, at all, lol?

Search the T6x Forum for posts from member QWERTY Andreas, he has done such mods.
Re: Looking For ThinkPad T61 4:3 Motherboard
Getting a Core 2 Quad to work in a T61 motherboard will require insulating pins labeled D8, AA7, AA8, AC8, AE8 and soldering a wire connection from pin AD26 (GTLREF) to pin D22 (GTLREF_2). You can leave the 1066MT/s modification out, but only if you have a QX9200 or a QX9300 installed. I believe this should be easy for people that know how to solder and insulate pins properly.nightninja96 wrote: ↑Mon Jul 16, 2018 7:47 amHow about the core 2 quad, I know how the process goes with it, but how hard is it?

There is no known way of getting a Q9000/Q9100 back up to speed without the 1066MT/s modification applied, unless it is one of those qualification samples/engineering samples with an unlocked multiplier. That is the reason why I said you can leave out the 1066MT/s modification if you have a QX9200 or a QX9300.
The Core 2 Quad is stable in general, but they do generate a lot of heat. Not even undervolting can keep it down to acceptable load temperature levels at 80C and below as far as I know.
Re: Looking For ThinkPad T61 4:3 Motherboard
I'll add my 2 words to Screamer's note:
Quad-cores are impossible to use in R61i without SERIOUS undervolting, and forget about QX series.
They do work in T-series remarkably well, and do not heat up THAT much, especially 15-inchers and 16:10 units. QX series produce some trouble I think I sould make some tests on units I have.
