Need Help - 1640 with a 1645 motherboard

Hey guys, I was on chat with dell a few months back and I was telling them to replace my motherboard and processor and I was complaining about heat. Anyway during the whole convo I was joking (not really) about giving me a 4670 motherboard instead of the 3670. Well I have had the parts for a month now and was just going to return them because I didn't feel it would change anything replacing the same parts, knowing that the xps just gets warm on it's own. (and yes I undervolted, helped a lot and added more thermal paste)

Any to make a long story short the dell tech sent me a motherboard now with a 4670 ati chip on it. The processor was the same but man am I stoked. Anyway is my computer a 1640 still or a 1645. Should I update any other drivers besides the video card. My service tag is irrelevant now also when downloading drivers.

Please help, thanks.

 

Depending on the processor.


If you have a C2D, then it's a 1640.
If you have an i7 720Q, 820Q or 920Q, then it's a 1645

But congrats on getting a better video card. You'll notice the difference almost definitely.

 

No it's a core 2 duo, same processor as before t9550 2.66 6m. Also I started getting errors and windows was acting funny after I replaced the board. I forgot my other processor was undervolted so I guess this processor is not stable at those voltages.

But I'm just checking if the chipset drivers are different or anything else.
