These are the kinds of responses that are less than helpful. Sometimes you wish that people would just choke back that need to be heard on subjects they know little about.
GMNation, if you still frequent this board, I have spent no small time with a number of Wistron 303c board based laptops and the answer is yes, you can overclock the hell out of this board.
What you need is to download the 186.81 vid drivers from Nvidia, make sure you get the correct version i.e. either 32 or 64 bit depending on what op system you are running. Then download (also from Nvidia) the latest version of system tools- should be version 6 something.
Hopefully the case you have is somewhat easier to deal with than what I have, but perhaps since your temps are already very low, ( 46 C at 90 load seems more likely to be the cpu temp and NOT the "cpu core" temp which is more important...I'd suggest Lavalys's Everest 5 for monitoring everything on the board...) but if indeed your unit is posting these kind of temps, then you are good to go. Note, the heatpipe used is more often than not barely adequate , so ...if Everest is showing temps of the cpu core, gpu core and mcp in the 80C range at load, you need to pull the board out, pull the heatsink/pipe off and shim and re-bed the thing with arctic silver or comparable. You want to make VERY sure that ALL the chips contacting the heat sink (on the compaq boards i've seen there are 4) are properly shimmed up to get good contact so as to achieve maximum heat transfer to the exhaust.
Now, your Turion X2 is going to run a bit warmer than the Sempron 42's I've been playing with but I can tell you for a fact that the average sempron can be pushed easily to 2500, and a good one will run solid at 2600 at 100 percent usage at around 70 to 74 C. Your mileage may vary but being the same family, I suspect you can do nearly as well.
Second, for gaming you'll find that your 8200m g can be substantially tweaked as well if properly shimmed and bedded..(its under the same heat pipe on the CQ's i've seen. Most of the ones I've fooled with have come stock with 400/667/800 timings and can be goosed up to run at 550/750/1500 which will net you a greater than 55 percent increase in 3dmark06 scores. You do this using Nvidia's own System Tools. Be careful, watch your temps, and make your increases carefully and incrementally. As always, some run better than others but all that I have fooled with have been able to comfortably run 500/750/1200 or better.
With your big heatsinks and fans, you should be able to push way past what I've done as..
drumroll...
the boards I've been talking about have ALL been in laptops
The above procedures on a CQ60 419WM (the 299.00 Wal Mart Special) resulted in going from a 3dmark06 of about 745 to 1172.....with the sempron s1-42. MBoard is a Wistron 303c using stock bios.
Good luck and have fun.
