Install fastest cpu and increasing ram over 4gig in my T61

[Taz1956]

Hello, Taz1956 here and new to site. a little bit about myself:
I have a great amount of experience building computers and have been into my T61 many times doing repairs, and also in my wife's T61 replacing cooling fan. Very well made, and built to be taken apart! I have been in many other make laptops, and by far, IBM/Lenovo is the best I have seen.
Having said that, I also support networking at my job as well as desk support and very much involved with virus/malware removal. To this day, I have never been NOT able to remove unwanted garbage in any one's machine to date. (proud gene working here).

I love Lenovo! That said,
* I would like to upgrade my present 2.4ghz CPU to the fastest that is possible.
* I would like to upgrade my present 4gig ram to largest that is possible.
* We use a docking station for both of our computers and do not want to replace old laptops/old docking stations for new.

I have read, and looked at videos of upgrading this laptop and would like anyone that knows, or has done it... past the point that I presently am at now) would be very appreciated. So,...
* What is the biggest CPU I could shoehorn into my machine?

* What is the largest amount of ram I could shoehorn into my machine?

You seem to run Penryn motherboard, which is great.

CPU upgrade options:


I would recommend T9300 which is best value for your money when it comes to a faster CPU.

T61 supports up to 8GB ram.

But the biggest difference will come when you replace the slowest part in your system - your hard drive. Put a good Crucial/Intel SSD in the main bay, and use other hard drive in the Ultrabay for storage.

But above that all, I would highly recommend to install the MIDDLETON BIOS which will unlock some forbidden fruits on your T61 like SATA2 speeds.
For more info you can check http://t61.wikispaces.com/

Thank you!
Well, I did not know that this mobo can support 8gigs. I should have purchased that before I bought the present "best" 4gig memory last year.
OK, now I always updated all bios from other machines and mine when needed, but never switch over to a 3rd party Bios.
I am afraid I might brick the laptop. I need to read up on this. I will read your supplied link.
With maybe using the fastest (non Core2 extreme) T9500 2.6GHz CPU as apposed to your suggested T9300 2.5GHz CPU, who,or what memory company could recommend which 2 sticks of 4gig ram to be the best for these changes?

I'm happy so see that I can get another 6 years out of my laptop. It just keeps on working and working.
Wondering if I could replace the GPU also?

Note: I am already using ssd, (which is slow now) compared to Samsung's new ssd's that are out.

Thanks again.

You're wasting money if you buy a T9500 instead of a T9300, T9500 is only 0.1GHz faster but costs a lot more.
Recommended RAM: Hynix, Elpida, G.Skill, Mushkin, Crucial, Axiom, Samsung.
Stay away from so-called ValueRAM (such as from Kingston) as well as the cheapo junk from eBay.
Middleton's BIOS has been applied thousands of times, no problems there.
Make the self-booting CD, then run that using the CD/DVD drive from inside your T61.
Before you do, check in BIOS that Config/Network/Flash over LAN is ENabled, no passwords set, and that Enduser is allowed to flash BIOS in the Security settings.

Thanx for the speed of light reply.
Yea, I know about the cheapie ram. I stay away.
Thanx for info on using the 9300 instead. I will obey! Looks like you have been here before time and time again.
Thanx for reminding me of the bios password, yea have one of those.
I will take your word that this bios has been proven.

+1 for the middleton bios - tried and tested! You shouldn't worry about it. Post your results after the upgrade please

[Taz1956]

OK, I read the readme.
I see why you said to use the ISO to DVD because of the 32bitt limit on Lenovo bios.
three questions;
1. the ctr. + fn (first ISO) means it will save my original bios if no key combo is used at start up?

2. And if everything works with first ISO as the readme states, can I move the original bios to the ctr + fn key combo so my ThinkPad will boot normal without interaction?

3. Will I have problems with ram suppliers selecting the correct ram timings, type for this mod, or is there someone out there that has experience with what I am going to do?

Thanks again. I will do this upgrade probably in Feb.

What does everyone think of a used, tested cpu from ebay? see here> [url]http://www.ebay.com/itm/INTEL-CORE ... 4897.l4275
I am ready to buy.
And I need info on what memory I should use. Money no object, speed is.
And why can I not use 2.6GHz as apposed of 2.5?
And will I see a good improvement over my 2.4GHz going to 2.5GHz?
Is it because the L2 Cache goes from 4 to 6MB?

Gee, did anyone try running X9000*Core 2 Extreme SLAQJ 2.8 GHz 6MB on the T61 6459-CTO 15.4 screen,
CPU: 2.4

Thanx all

CPU's from e-bay should be OK. There was a slew of overclocked, remarked, CPUs a couple of years ago but that seems to have died down. You can use a 2.6GHz T9500 but it is a waste of money as you will notice no difference from a T9300, notwithstanding the larger cache. You may run into overheating problems with the X9000.

I got a few T61, all with a T9300, 4 GB RAM, SSD and of course Middleton BIOS. My Frankenpad have a T9500 and 8 GB RAM but frankly I don't notice any benefit from spending the money on a T9500 and the extra RAM.

Looks like you'll be shelling out a lot of $$ for these upgrades. Another thing to consider is upgrading to a T500 which have native SATA II support, takes DDR3 RAM which is much cheaper and will take a faster CPU. T500 and T61 will take the same dock and battery. I really like my T500(s) with ATI 3650 GPU and switchable graphics. A T500 can be had for cheap....but where does the upgrading end?

[RealBlackStuff]

As for M's BIOS, pick either option you want.
Don't worry about saving the 'old' BIOS, as you can get that from Lenovo any time.
If you want to 'swap' Ctrl/Fn again, you need to load the other BIOS version.
Buy some of the RAM I recommended, any PC2-5300 or PC2-6400 Sodimms from them will do.

I have probably built more FrankenPads (T60 with T61 motherboard) than anybody else on this forum.
I have used every CPU that is available for a T61, including the X9000.
With Throttlestop you can overclock that X9000 all the way to 3.60GHz.
Cheapest recommended CPU: T8100
Most bang for your buck: T9300
Most money wasted: T9500 and X9000, as well as more than 4GB RAM.

You've been told a few times what to buy, what not, and why.
Stop asking dumb questions, please.
