Dell D630 with nvidia 135M GPU: any system board revision fixed?

Hello Dell community,

I think about prolonging the use of my D-Dock environment by buying a Dell D630. I know about the nvidia GPU problem and I couldn't find any prove that there is a HW fix by Dell (e.g. new System board revision).

I know that there are two part numbers for the system board with nvidia GPU: R872J and R873J.

1) Is one of them a fixed one or suffer both from the same problem? If so, what is the difference?


If there never was a hardware fix by Dell, does it make any sense to:
2) try getting a system board produced later (e.g. close to september 2008) or within a specific period?
3) use a copper shim to improve heat dissipation of the GPU as some people recommended?
4) use the "new" heatsink DT785 as described here: http://www.sevenforums.com/pc-custom-builds-overclocking/180440-dell-d630-cooling-mods.html

I use get a T9300 for acceptable speed on the board.

If somebody has a many-years experience using the D630 with nvidia GPU and still not having the video problems, that would be a great to know. I could improve my guess whether it is worth the hassle to get a D630 or not (or get a D630 with Intel GPU - but I'm not sure if the Intel GPU is up to the task of the 3D Unity Desktop Environment on dual screen, so that's my reasoning getting the nvidia board).

Usage: dual screen with Office + Internet + sometimes a Virtual Machine + (!) watching movies. I currently have a D430 but it can sputter with 1080p movies, 720p mostly work fine. The D630 should not only give me a faster VM but also a better movie watching experience.

thank you,

Tim
