Thanks for the kind words Aero,

 

btw, since I see you have a nice maxed out 14" widescreen T61 I thought I'd ask if you're interested in any of the rare options for this model. I had collected them to build an ultimate 14" wide for my daugher but when she saw a rare 15.4" R61 I built, an august 08 unit with webcam she stole it from me,so I'm probably willing to let some of these parts go or perhaps build it for myself. I have all the parts to add webcam, 4in1 card reader, high resolution screen, even a brand new NOS motherboard with 2010 dated GPU chip.

 

The main thing we needed was the webcam, a good sound nVidia gpu and 8gb of ram so the best options were the 14" widescreen T61 or a rare high-end 15.4 R61. I was going to build her a Z61t with the beautiful Titainum lid that I picked up, it's truly a beauty and an amazing laptop, but unfortunately they won't support 8gb of ram and like me she likes ot multitask so needed all that ram.

I have a lenovo T61 and it is my main Computer, i use this machine for everyday work and also to code, if you are going to use tools that are memory intensive like Visual Studios, image manipulation programs... if you need virtual machines, putting on it 8GB DDR2 and ofc an SSD disk of about 512 GB will make your work a lot more pleasant, but if you want only to speed up your machine, avoid the RAM upgrade and put a nice SSD and you will notice a great speed increase.

 

RAM for itself won't make that much difference as the cpu upgrade options for this machine, on the benchmarks the supported more expensive and more powerful cpus available like the Core 2 Duo T9500 don't make up in performance to justify the investement, compared to my T8100.

 

Though an old machine I will have any pepsi challenge to any of those new notebooks that cost around 200 to 300 euros, i love this keyboard and the realibility of this machine so i pimp it out to endure some more years.

I absolutely agree about the SSD.

 

I had done just about  every upgrade - the CPU, RAM to 8 GB, previously had a 512 GB 7200 RPM Western Digital drive, and used the Middelton  BIOS to get the drive to SATA-2 (the BIOS made a big difference and has been perfectly stable, so fear not).

 

Given the profoundly lower price of SSD's, I've put a Samsung 850 Pro 500 GB drive into all my T-61s, and a T-60 as well.

 

The results were worth every dollar, Euro etc.  Booting to Win 10.1 takes about 40 seconds, Repetitive read/writes to databases markedly improved.  I now have an appreciation for just how much the physical disk drive latency (not the SATA interface) was slowing things down.

 

Looking at Task Manager, one of the major boot slowdowns was due to Kaspersky scans at boot-up.  The time to do Full AV scans has plummeted as well.

 

My only last change will be a WXUGA LCD panel that I found at a remarably reasonable price.

 

So it's good for another 5 years.

Hi,

Which RAM memory exactly do I need to upgrade my T61 to 8GB (2x4GB).

Thanks,
Rene

prefered: ddr2 pc2-5300 200pin sodimm

 

the cheaper ddr2 pc2-6400 200pin sodimm should work too. 

 

avoid generic and private brands

Wauw TuuS,

That's a quick answer. Thanks.
Will I see the difference? I already have an SSD in my T61. But with the 4GB (2x2) installed now, it gets slower. The OS is Windows 10.1

Gr,
René

I'm running my garage Lenovo T61 with 4GB RAM and 32bit Windows 7 (32bit for specified reasons). The kernel is hacked (PAE enabled) so all of the 4GB is usable. I'm going to upgrade the memory to 8GB soon to see if that works also for me.

Most of these PAE hacks are based on the code used in windows server 32bit editions, all of which will run 8gb on a T61, so it should work on yours too, however there are additional memory limitations to using x86 (32bit) architexture, for example there will still be memory limits per process. Some apps have worked around this by dividing into many processes, but your best option is almost always a 64bit OS, but I do have a copy of windows server 32bit running on my T61 so I can test how software products perform in a 32bit windows environment running over 4gb of ram.

Yes, I'm aware of the 32bit architecture limits. 64bit OS is not an option for me because in my garage I'm using some software (Saab/Opel specific SW) that just don't work in 64bit environment. 8GB RAM is already on the way... maybe in 2-3 weeks I can test those.
