This is a mini guide to overclocking the Satellite L25 series. This laptop was offered at low cost on a few black friday sales, so I know there are more then a few overclockers who own it.
This laptop comes with various cpu's. Mine had a Dothan (Celeron 64K L1 1Mb L2) at 1.4ghz 14x100 (400). It also came with 192mb 100mhz ddr2.
I found a how to on pin modding the cpu to run at 133. You can see that here http://www.notebookreview.com/default.asp?newsID=3226
But I was not satisfied with 1860mhz 14x133, so i loaded up the program called clockgen and went through the pll's one by one until I found the one which works. Just so you all know the pll is ICS 954119, and it has fsb adjustments in 1mhz increments from 100mhz (400) to 500 (2000). i doubt any of these satellites would ever make it to 500 though.
But I was able to take mine to 166! Anything higher and it freezes up running prime95. going from 100mhz fsb to 166 means my 1.4ghz cpu is now sucessfully running at 2314mhz. thats a pretty sweet overclock. And it's prime stable after 12 hours.
I had previously taken the laptop apart to replace the thermal pads on the heatsink with artic silver. this dropped the temps 20 degrees. If i had not done this I very much doubt i would have gotten this high of an overclock. So before anyone goes off on their overclocking binge, take the laptop apart and replace the crappy thermal interface matereal with some good ol artic silver. There is an excellent how to guide on the L25 disassembly here. http://www.irisvista.com/tech/laptops/ToshibaL25/satellite_L25_laptop_overclocking_1.htm
I also installed 2 gigs of 166mhz ddr2 ram if that matters. Overall the overclock and ram upgrade made a nice difference in usability. Internet webpages with graphics and flash files no longer studder or skip., and i am able to play lightweight 3d games at the full 1024x768 resolution such as torcs and trigger, and still get a respectable 40+fps with the details set on high.
My next step is to try overclocking the intgrated ati video chip. I'll let yous know how that turns out.
Maybe in a year or 2 i will upgrade the cpu to a real Pentium M 2ghz with a native 13mhz fsb, and overclock that to 166 or higher.
