Finally, I got mine working well with Dothan 1.6MHz Processor, overclocked at 2.16MHz. Thanks all for your help!!
Here's a summary of my D600 spec:PLL:
ICS UA430435 (It's diff. model thn OP, but I got it working with the same method.)CPU:
Dothan 1.6GHz (My original cpu was Banias 1.6GHz, but was not stable at 2.13GHz
- So I bought Dothan 1.6GHz from ebay $13CAD shipping included.)
Combo 1: Moded 512MB PC2700 Card by Kogee* + 256MB PC2700 Samsung**
Combo 2: 256MB PC2700 Samsung** + 256MB PC2100 Samsung***
Both configuration worked well. For someone looking to upgrade ram, modding one PC2700 to run at slower speed would be a great option.*PC2700 ram was reprogrammed to run at the speed of PC2100 by using another laptop. Some Ram Card allows ROM Flash and some doesn't.
**Original Ram from Dell
*** Purchased locally for $10CAD
Getting to the PLL was tricky, but ended up taking apart all the components and the entire process took a good 3~4 hours.
CPU Temperature seems to be ok, with fan running at mid speed @2.13GHz. After cleaning dusts off of fans and heat sinks actually helped.

My D600 is my main computer. Actually, I was in the market for getting a new laptop, but after this mod, I decided to wait a little more for a better deal after Xmas. I still have both primary and secondary battery holding full charge (4hrs++) and it can play decent games as well.
I was able to see increase on fps on 1.6 and was able to play CS source, which I wasn't able to before the mod. How great!!
Thanks again everyone for your help!!
