T61 and 8GB ram?

[mnadig]

I understand I'll need a 64bit OS to address over 4GB, but I'm confused. Crucial and Lenovo seem to say my T61 (model 765803u) will max at 4GB which is what I've got now. However, this post  and this blog indicate 8GB is possible. What's the definitive way to determine the max? A few co-workers also have T61s and I'd like to see if all of them are upgradeable.

Another co-worker has a T60 (model unknown as of yet). Crucial and Lenovo report max a 3GB for that. Any special cases for the T60 ?

Thank you.

T61,X61/t does support 8GB ram if you are running 64bit OS. However, T60 does not , coz T60 is not Santa Rosa system.

Thank you for the quick reply. Are all T61s "Santa Rosa" systems or just particular model #s?

This "definitive post on T60/T61/p memory limitations" on thinkpads.com forum indicates a 4GB limit for all T61s. This is nuts...

The GM965 Intel Chipset on the T61, X61 and R61 can support 8 gig of ddr 2 ram, and many people have successfully done it in their T61 and X61.

Thanks again for the quick, helpful reply. I just put 2-2GB in my T61 for $19AR from a deal at Frys.com. However, all my searches for 2-4gb ddr2 is resulting in hundreds of dollars ($679 from crucial for 2-4gb pc5300) for the pair. That's crazy. Am I missing something?

it used to be around 200 USD for one stick, now it should be around 90 USD.

Thanks for the ray of hope.  My T-61 is now a Ubuntu machine and I would like to run the 64 bit version.  Of course I can only justify that if I have 8GB of ram.  But, like your earlier correspondent I'm finding it to be at least $250/4gb stick.

Can you point me to a dealer who has it for around a C-note/4gb?

FYI, I put two of these G.Skill modules in my T61 - works great with Vista Ultimate 64-bit

Thanks for the heads up.  Now my only problem is to convince my darling that I need memory that gig for gig is twice as expensive as her new Cori-i7.
