T61p motherboard in T61

2015-01-11, 4:01 AM

Howdy y'all!


I've got an elderly T61 I've become rather fond of after using it for school and decided it could use an upgrade. I'd like an Nvidia motherboard (yes I know about the issues). But I've got two questions.


Firstly: could I use a T61p motherboard in a T61?


Secondly, would that get me anything (looking for an uprated graphics card), and would there be any hardware hacking involved (bigger fan, new heat pipes needed)?

The trial never ends, Picard.

Hi and welcome to the forum. 


The T61 came in three sizes, 14.1" standard, 14.1" widescreen, and 15.4" widescreen.


The T61p was available in 14.1" standard and 15.4" widescreen only. If you had one of these sizes it would be possible but for a 14.1" widescreen the most powerful GPU option is the nVidia nvs140m. The fx570m is a more powerful chip so performance would be better on 3D graphics that were written to use nVidia and not intel gpu chips but their rate of failure is also higher, at least for those units built before August 2008. What we've seen in the forum is about 2-3times the numbers of fx570m failures being reported and if you consider there were vastly more of the nvs140m laptops out there the conclusion is they are more reliable. It's also been widely reported and confirmed that the nvs140m gpu is basically an under clocked Gforce chip and there are many confirmed successful reports of massively overclocking these chips as much as 70% without any adverse effects or dangerous temps, however I recommend caution when pushing hardware beyond it's design limits, but if you monitor temps and are careful you can probably get performance approaching that of an fx570m. 


Good Luck



ps. If installing an nVidia FX570m board in an NVS140m model no modifications are needed, if installing in an Intel model you will need a discrete heatsink/fan assembly.
