Found good offer for rare T61 4:3 with Intel graphic on (maybe) Penryn board.



If I put serial number L3E0430 and machine type 8895 on http://support.lenovo.com/en_DK/product ... ookup.page there is 44C4237 42W7872 PLNR CRD but machine is dated 08/03 and somewhere on forum I found that T61 4:3 Penryn are dated 08/08 08/09 08/10.

I am not Vista user, and just to be sure, where mbo number can be found inside Vista?

T61 and R61 series with Penryn boards were first shipped in the January of 2008. I've seen many - both Intel and nVidia - from that era, and still own a couple.

It's the nVidia boards with "safe" GPU chips that were dated 08/08 or later.

No clue on how to answer the Vista part of your question, though.

Enjoy your "new" T61.

Your motherboard 42W7872 IS a native Penryn board!

That machine looks like it originally shipped with a low-end cpu, the T7250 merom cpu so it's odd that it got a penryn board. I suspect since it was a CTO system that the day it was assembled there were no 43w7648 boards on the shelf so they used the 42w7872 instead. If I were you I'd get a Penryn cpu chip for it. If you're on a budget go for the t8100, it's the coolest and most efficient and perhaps the most underrated chip in the core2 series. Performance wise it will vival a T7700 which is the fastest merom used in general production and in extreme cases when temps get hot either from environment or usage, the penryn can go much longer before thermal throttling occurs so if you think of the tortoise and the hare parable you'll understand why and when the penryn out performs even faster chips. If you want all out performance go with a T9300 or T9500, although the latter is expensive and risky to source. The T8300 will give you the benefit of the smaller more efficient die but with a faster clock speed and are also more affordable than the T9xx versions.

Enjoy your unique T61
