Re: Install a 1066MHz FSB CPU on T61

The fan spins up, the power light goes on, LCD backlight stays off and no image appears on the screen. I tested with a 90W power supply.
Today I tried it with a board that has the nvidia nvs 140m instead of the intel x3100 and it did not work, too. The RAM was flashed to FSB 533 with the timings from the FSB-800-profile, which worked at FSB 1066. RAM clock was 356 MHz at FSB 1066 and should have been 440 MHz at FSB 1333. The RAM is most likely not the problem because it works at 440 MHz when it is flashed to FSB 667 with the timings from the FSB-800-profile and the FSB is 1066. Only problem on the RAM side might be that tRCD timing where I could not set the value high enough.

This is the mod for the chipset BSEL inputs to support FSB 1066:

this is how I modified the BSEL pins for the test with FSB 1333:

In FSB1333 MOD
What is different between "VCC1R05" and "VCC_SRC"? I can not find "VCC_SRC" in T61's schematics and why you choose
"VCC_SRC" not "VCC1R05" to pull up BSEL2 of PLL?

Sorry, it is VDD_SRC, not VCC_SRC. Pin 16 at the SLG8LP564 clock generator. I chose this pin because it is 3.3V instead of 1.05V and according to the datasheet of the clock generator, the minimum input voltage to be recognized as "high" is 2.0 V.

But I did not have any success yet with FSB 1333.

Maybe you can try VCC1R05. BSEL2 is more complex. In some PLL chip,

FS_C./TEST_SEL -->3-level latched input
If power-up w/ V>2.0V (-0.3V) then use TEST_SEL
If power-up w/ V<2.0V (-0.3V) then use FS_C

I think intel may not use two different voltages to drive pll.

So I am trying to organize the required hard-mods in my head. Lots of work seems to have gone into simplifying the modifications. My goal is to use a QX9300. Since I presently have an X9000 in there, it looks like thermal performance and power consumption will be about the same.

Is my following summary of the required modifications correct?
1) Cut the "yellow marked trace" so that the chipset thinks it is locked at 200MHz. What are the specific ref-designators for the parts that this trace connects?
2) Install wire to connect D22 and AD26.
3) Add R160 and R215 as shown in this image. (provided by el-sahef)
4) Remove (or isolate) pins D8, AA7, AA8, AC8 and AE8.

The result is that the FSB will drive the RAM at 440MHz and the FSB itself will be 1066MHz with the chipset clock locked at 200MHz? One result may be that I need to mess with the RAM SPD settings unless I can find some DDR2-1066 modules somewhere?

I see some talk about running the FSB at 1333MHz...does tat change the above steps or does it involve extra steps? Sorry for asking about this, I am having a little trouble following the discussion since I don't have experience modding motherboards like this.

Thanks again! Great work.

You don't need to add R160 and R215 - they already soldered and waiting to be cnnected to D22 ;) It is supply for GTLREF. And it can be used as source for GTLREF_2.

You forget 1 thing - you need modified BIOS and modify ACPI table to run all 4 cores.
Good luck!

Thanks! So, just add some 30ga wire between AD26 and D22?

For the ACPI table...it looks like if I use the BIOS given in the following link that will be taken care of already? Quote from el-sahef:
-----------------------------------------------------------------------------------------------------------
Edit: A new mod BIOS is available from highsun @ 51nb.com that contains this modified apic table, so this grub2-stuff is no longer needed:

Time to start browsing eBay. Already got the heat sink from a T61p with FX570 and swapped a W500 fan into it. Very excited!

What is 30ga??? Just connect and try to make this wire as short as possible.

Please tell me what the differences between T61 (140NVS) and T61p (FX5700) heatsink. If you can point me to photos or thread where it was discussed.
My HMM tells me only 2 FRU - 42W2821 (for intel graphics) and 42W2820 (for nvidia - no difference - NVS or FX)????

PS
I have heard a rumor, that QX is better in terms of stability at normal frequency. So it can be U`volted. But it is rumors only.
Other thing that Q9000 is like penryn 3M (with half cache) while Q9100 and QX9300 are complete penryns.

30 gauge wire...silly America still uses Imperial units. The rest of the world would call it 0.05mm^2 wire.

The heat sink came from a unit that had the FX570M GPU, but you are correct that it looks like that is the same one for the NVS140M. You can see details about the fans and stuff in here:
http://forum.thinkpads.com/viewtopic.php?f=29&t=105114

I also undervolted my X9000 quite a lot and that helped a LOT with temperatures.

Is my following summary of the required modifications correct?
The newest version of the how-to is in the german thinkpad forum in the first post of this thread:
http://thinkpad-forum.de/threads/172581 ... ndervolten
I suggest you to read it with google translate (not nice to read, but it does work "somehow" ;) ) because it is more detailed.

The steps are:
1) Flash the modified BIOS that contains the APIC table and the CPU microcode. There are multiple BIOS files that can do even more, e. g. undervolting the nvidia chip (with quite pleasing results) and unlock PCIe ASPM. They were done by highsun, a chinese bios modder at 51nb.com. The thread in the german thinkpad forum contains links to all these versions.
2) Make sure that you use DDR2-800 RAM.
3) Cut the yellow marked trace and solder in the connection shown (green wire):
http://abload.de/img/266-fsbe2cow.jpg (239,26 KB image size)
4) Solder in the connection between the vias that belong to the socket contacts of GTLREF and GTLREF_2 as shown:
http://abload.de/img/gtlref-fryppy-neu45avr.jpg (334,04 KB image size)
This image shows how it looks like when the solder job is done:
http://joker4791.spdns.org/bilder/T61_C ... bottom.jpg (783,24 KB image size)
5) Remove (or isolate) pins D8, AA7, AA8, AC8 and AE8.
The result is that the FSB will drive the RAM at 440MHz and the FSB itself will be 1066MHz with the chipset clock locked at 200MHz?
Yes, the RAM will run at 440 MHz and the FSB will be 266 MHz (also called FSB 1066). The chipset actually runs at FSB 1066 too, but with the mod it thinks that it does operate at FSB 800 only. This has to be done because otherwise, the notebook will not start.

It is possible that your RAM will not run stable at 440 MHz , because with DDR2-800 (and DDR2-667) the BIOS will always use the timings from the DDR2-667-profile in the SPD (there are multiple timing profiles for different speeds). So your DDR2-800 RAM will run at 440 MHz (40 MHz more than DDR2-800) with the timings of the DDR2-667 profile. If this causes instabilities, then you must flash a SPD-profile that was edited so that it contains the timings for the DDR2-800-profile in the DDR2-667-profile. There is a profile for 4 GB sticks with 16 chips and a profile for 2 GB sticks with 16 chips in the thread linked at the beginning of this post that you can use.
I see some talk about running the FSB at 1333MHz...does that change the above steps or does it involve extra steps?
There are several people that tried this (including me) but as far as I know, nobody succeeded yet. With a QX9300, you do not need that anyway because it has an unlocked multiplier. So for overclocking (if you want to do this), you do not need to raise the FSB to 1333, you should be able to just raise the multiplier with a third party software.

This is good summary table (for T61 BIOSes). I have thought about undervolting nvidia GPU by pinmod. But BIOS modding is simplifies this step.
And another question - your T61 C2Q based on penryn or merom (old) motherboard? Can merom (old) motherboard be used for this mod? Have this BIOSes termal sensing error correction like Middleton's BIOS?

Good thread :thumbs-UP:

When our friend RMSMajestic have passed his exams i will congratulate him and ask to talk with his Chinese friends from 51nb.com about the possibility to create C2Q bios for the T(W)500. I think it is possible. Especially now, after obtained such excellent results at T61 modding. I will waiting it with my T60/500 mod.

Finally, no more maths in my life ever :mrgreen:

I've just put quad cores on my T61s and noticed some bizzare problems.
1. the lowest clock speed is 1.6Ghz, shouldn't it be 0.8Ghz?
2. Even stranger, two of the cores were operating at 2.5Ghz and the other two were operating at 1.6Ghz. I can only use throttlestop to push the other two cores to 2.5Ghz. Similar things happens on my Q9100
3. Under windows XP, the CPU constantly operates at 2.5 Ghz/1.6Ghz for QX9300 and 2.26Ghz/1.6Ghz for Q9100. and under windows XP it's about 30 degrees hotter than windows 7

It happens on both of my T61s so I don't think I'm an exception
I reckon this is the problem of power manager/APIC/ACPI, any ideas?

I forget to say, but i thought you knew. All C2Q CPUs have lack of SLFM. So making T63 (T6x + C2Q) is actually making W63. It is mobile workstation class notebook. Battery lifetime become reduced in favor of greater computing power.

What was the CPU load? Try to use 7zip testing (benchmarking) function and note how CPU works on different multithreaded patterns.

What ACPI tables you are using? Have you flashed BIOSes with quad-core ACPI - mentioned some posts upwards in this thread?

Are all of your T63s have penryn mainboards? Or this mod can be done on merom mobos and C2Q BIOS hide termal sensing error?

And my personal request.
Can you ask 51nb.com's fellows (may be highsun) about T(w)500 quadcore bios mod? I don't know chinese language to register this forum. And i think it will be a bit of pain for everyone to converse with google translator in this forum.

I really doubt it that T61's battery can provide enough power for T61. You can see the size of W700's battery

Hi, big thanks to RMSMajestic and el-sahef. I replaced my t8300 with X9100 using your pinmod and bios - it was so easy :D. The only problem I have is that there is no well known way to overcklock X9100 under linux. I've tried and looked into intel-phc and c2ctl source code and it seems they could not overclock intel extreme processors.

Does any one know which MSR register unlock multiplier? I'm able only downclock using 0x199 register.

I've installed watercooling on my 15" T63p and finally brought the temperature under control (reduced by about 10 degree celcius)
details here
http://thinkpad-forum.de/threads/172581 ... ten/page15

@mdancer
I'm not that familiar with linux, but you might have to "hack" something on linux by yourself
Try search forced Dual-IDA (always at IDA clock speed) on linux on thinkwiki and you might find something useful
Or maybe @el-sahef can help you with that

@qwertyandreas
I saw that you've received the Q9100, could you please share your experience here? :D

RMS, what heat sink and fan were you running before that were giving you thermal issues? I have found that both the type of thermal paste used, AND the co-planarity of the heat plate to the silicone surface are crucial to efficient cooling. Most off-the-shelf thermal pastes are junk, truthfully. I work in consumer hardware as a mechanical / thermal engineer, so I guess I am spoiled in my selection of industrial thermal compounds. One very good one that you can probably get samples of online cheaply is Shin Etsu G751. The stuff is messy and a real pain to apply, but it conducts heat very well AND it performs well over time (high reliability). Many pastes suffer from "pump out" due to thermal cycling, and G751 is very good in that respect, meaning years of hassle-free service. A better one is Honeywell T880 thermal grease...messy but easier to work with, and slightly better conduction than G751 with similar long-term reliability. Not sure if you can find samples of that online though.

The X9000 CPU (45W TDP) I have combined with NVS 140M GPU both stay down to reasonable temperatures under heavy loads with the T61p discrete-GPU heat sink and W500 fan and Honeywell PTM3180 phase-change material. It's the easiest to apply since it is a sheet rather than a grease, and it seems to have better performance initially and over time versus the 2 greases (although they are both still worlds better than commercially available stuff). You MIGHT be able to request samples from Honeywell. Just remember to take the plastic film off of BOTH sides if you get some! Anyway, if you ever decide to give it a shot let me know and I can give you some pointers.

Got pics of your water cooling setup? I didn't see any photos in your link.

@bmwman91
when I had thermal issues I was using T61 intel-graphics heatsink and T60p's original heatsink, and both are confirmed to be a lot worse than T61p/W500's heatsink
Regrading the thermal paste, I believe that "any problem which can be solved by money isn't a problem". :D For example, the coollab liquid pro costs "only" about 10GBP, and the good-old Arctic Silver 5 is only 5 GBP, barely anything compare to a 80GBP QX9300
I used Arctic MX-2 between heatsink and CPU, and MX-4 between copper tube and heatsink, mainly because my MX-4 has been lying there for 3 years and it's now performing even worse than MX-2, and also in the next few month I might still take the CPUs out so I didn't use liquid metal
It'd be much better if you can find low temperature solder and solder the copper tube and heatsink together

watercooling: initial thought

Very cool! (there is a pun in there) I like it.

I wonder if you could build a small heat exchanger that fits into the ultrabay? THAT would be super awesome...fully self-contained water-cooled Thinkpad.

For anyone else who wants to try a quad core in a T61, I have a time saving tip that also reduces risk. Part of the procedure is to cover some of the CPU pins with insulating wire and then drilling holes in the socket so that the CPU will fit. An easier method is to simply remove those pins from the CPU. I've done it before when I couldn't use a nearby pin to bring another pin to ground. Take some needle-nosed pliers and gently move the pin you need to remove back and forth. It will soon feel much looser and then it will break off. I used to do this a lot to BSEL mod socket P Celerons (they wouldn't revert to a 6x multiplier - they couldn't).

Yea - i did it before http://forum.thinkpads.com/viewtopic.ph ... 30#p728666 - Hedgehog is shaved ;) But photo is lost :(
But these days i tried this on W500 mobo and have no luck.
Working with sharp tweezers is Ok, but i have used another approach - using hard but thin insulated wire. Put it on pin AND CHECK that it IS CORRECT PIN! And swing in diagonal direction.

@bmwman91
That'd be quite hard, especially if you want to keep the ultrabay available for Optical drive or 2nd HDD,
But interesting idea :D
three hard things:
1. connection between heatsink waterpiped and circulation in the ultrabay
2. How to fill the circulation with water
3. air intake for fan in ultrabay--- from where?

@Qing Dao
nail top cover(指甲油) works the best :D
P.S. do you have a 51nb ID?

I saw a QX9300 for 99GBP on ebay today, I'll PM you with the details of it

I want to say thank you to el-sahef and FryPpy. Thank you for proving me right, I'll post a link to this topic in the DRAGON Lounge :) I had this theory from quite some time. I even got a QX9200 QAVR (everything works fine, tested on a (QuadCore)modified DualCore M570TU (with my help :) )) last summer. Well in the end I gave up, never got to the soldering. Kudos for you guys and for the much simpler mod :bow: I thought that a lot more would be involved.

Ah, I think I read that before but I didn't understand it. Nail polish.

No, I'm not on 51nb.com. I'm not a native Chinese speaker, so while I do read threads on there, I have a lot of trouble with technical computer terms.

@Qing Dao
Well, I was told that nail polish is for the colour and nail top cover is for protecting nail polish---- more friction proof
I don't know if it's true or not as I don't have a girlfriend.
=============================================================
Okay guys, here are the further problems/observations I've observed with the quad cores

1. amwrdfe@51nb pointed out that C0 stepping Q9100 ES (QDRS) does not work on any of the BIOSes
It's unlikely to be problem with anything else as he's having Q9000 working perfectly fine
2. When I overclocked my QX9300 at 3.06Ghz(@1.1625V) and run it under full load for about 10 mins, my laptop automatically restart itself without any freezes/BSODs/warnings, where temperature was only 70-72 degree celcius(on hybrid cooling). Changing the power adapter to a 135W one did not help with the issue either, I guess T61's CPU power supply is just not enough to handle an overclocked QX9300.
3. My method of hybrid cooling reduces temperature by about 10 degree celcius, and it can remove approximately 8-14W of heat :mrgreen:

I'll include detailed tests and pictures tomorrow

@ triturbo: I know that thread and the tests that Ricki Berlin posted there with his HDX9000. Since he got quite far, it encouraged me to get involved with the quad core mod subject on socket p thinkpads, first on mainboards from T500 and R500 (link) which was unsuccessful because of the BIOS, later on the T61. If he is still active on NBR, mabe you can post him a link to this thread: http://thinkpad-forum.de/threads/172581 ... ndervolten
It is more detailed and since he is German too, he will understand everything. I think it should be also doable on the HDX9000, but it is very likely that one needs to use the APIC table loading method via GRUB2 bootloader on these machines (unless someone creates a mod bios with the quad APIC table for these machines too).

@ RMSMajestic:

to 1) Seems to me that the BIOS does not contain the microcode for the C0-step quad core ES, since R0-step and E0-step quads work (regardless if they are ES or not).
to 2) How did you manage to raise the multiplier on your QX9300? I tried it with throttlestop and it did not work for me. Seems that I am doing something wrong here.
to 3) I will get a T61 4:3 nvidia cooler in the next few days and I have a spare T500 ati cooler where I can take out the fan. I want to use the heatsink of the T61 nvidia cooler and the fan of the t500 ati cooler like bmwman91 did it in this thread, since T61 heatsink has bigger left radiator than T500 ati but the T61 fan has a maximum of ~4500 rpm and T500 fan of ~5000 rpm. But I will cut away the black plastic of the t500 fan base that blocks airflow to some of the fins of the T61 nvidia heatsink and I will drill some holes in the base cover as suggested here so that the fan gets more fresh air from the outside.

The 4:3 T61 nvidia cooler and the 16:10 T61 nvidia cooler differ a bit in the area where the heatpipes are soldered to the back radiator. On the 4:3 model, the heatpipes for the CPU are a bit longer and soldered across the whole width of the copper base plate for the back radiator. On the 16:10 model, the heatpipes for the CPU are shorter and soldered only across half the width of the base plate for the back radiator. The other half is covered by the heatpipe for the GPU. That might also have an impact on the CPU cooling performance.

Nail polish top coat is the best name for it I can find. I feel like something with color would work best though; you could see how well it covers everything and easily check it for damage.

Both of these problems might be related to the voltage regulators not being able to provide enough power. When a computer boots, the processor (and almost everything else) draws a lot of power for a little bit. For example, if you run into a situation where the laptop starts but doesn't load the BIOS, the fan will be spinning at full speed and the computer will get very hot. The M0/C0 stepping Penryns are a lot less energy efficient than R0/E0 stepping processors.

Have you been able to see how hot the voltage regulators get on your computer while running the QX9300 at high speed? Perhaps providing cooling for them would help. Normally they are just bare chips without any form of cooling on them. Also, have you looked at all of the temperature sensors and not just the one for the processor to see at what temperature it shut off at?

Okay here it comes:
Room/water temperature: 27 degrees celcius (measured by thermometer)
It's impossible for me to recreate the 20-25 degree celcius environment now, summer's here

Watercooling mechanism using siphon principle
https://scontent-b.xx.fbcdn.net/hphotos ... 9851_n.jpg

All tests are done at default voltage

T60p+ QX9300 2.53Ghz*2+1.6Ghz*2 on hybrid cooling, fan contolled by BIOS, final temperature ~70 degree celcius
https://scontent-b.xx.fbcdn.net/hphotos ... 5398_o.jpg
T60p+ QX9300 2.53Ghz*2+1.6Ghz*2 on air, fan contolled by BIOS, temperature got up to 88 degree celcius, then throttles
https://scontent-b.xx.fbcdn.net/hphotos ... 2705_o.jpg
CPU throttles after about 10-15 mins

T60p+ QX9300 2.53Ghz*4 on hybrid cooling, fan 7 in TPFC, final temperature ~76-80 degree celcius
https://scontent-a.xx.fbcdn.net/hphotos ... 7362_o.jpg
T60p+ QX9300 2.53Ghz*4 on air, fan 7 in TPFC,
https://scontent-a.xx.fbcdn.net/hphotos ... 3200_o.jpg
temperature got up to 88-90 degree celcius, then the laptop shuts itself down (I reckon it's due to overheating, cos my T61 didn't restart itself)

How effective is the watercooling?
Under T60p+ qx9300@2.53Ghz *4, I ran the stress test until the water in the source bottle was drained out(about 1 liter in total)
Then I measured the temperature of the water in the dumping bottle, it was 35 degree celcius, 8 degree celcius rise in temperature.
So the heat absorbed by water is 4200J/kgC*1*8C = 33600 J :bow: Crazy QX9300 :/
the water was drained out in 58mins.
So the heat removed by the watercooling is at least 33600/3480= 9.655 W
But since I had a 1 meter long thin tube carrying water to the dumping bottle, great amount of heat could be lost to surroundings during this process
Hence the actual result will be much higher, maybe even doubles.

Conclusion: that tenny tiny tube carries away 20%-35% of heat produced by QX9300, and there is still very large room for improvement! :mrgreen:
