I just thought I'd share me 2 Dinar w/ my experience on this topic....
There is no real "overclocking" possible w/ Acer Aspire 5050, though I could get some performance boost w/ powerstrip. Could get a minescule 101 MhZ increase....from 300 to 401. Never managed to find PLL for my lappie for clockgen overclock....
Anyway, however, I recieved some VERY pleasing result when I used this utility called mobility modder.http://www.techbeta.org/hardware/ati-mobility-modder/
One MAJOR issue of GOAT In this card is the laptop driver. NEVER could find an upgrade for it and it's seriously outdated and abandoned. Using this tool, I could get latest drivers 4 catalyst and thankfully, mobility modder supports the ati 1100x which comes with it
Before i installed this app (Windows 7 ultimate btw), even w/ powerstrip I tried running BF2 it would play on lo-res but crash after 10-20 sec or FPS would drop, but after this fix, and getting latest driver from ati and moddin' it w/ this nifty lil tool, I can now play BF-2 stably albeit on lo-res.
On windows 7 ultimate I had issues w/ power strip, in sense it would sometimes say "your clock is abnormally reading" and clockspeed would b at 100 Mhz. Didn't notice a diff there but when I watched the hi-res divx movies, it lagged sort-a. U just gotta keep loading profiles till it somehow mysteriously get fix if this happens
Hey I am no lap ace or any ace, just shared my experience so far w/ my lap... my point was has anyone w/ this lap used mobility modder and updated latest driver for gfx card? instead of stick on 2 one which came w/ lap and try "overclocking" etc...? I have yet to find a good overclocking tool which supports integrated notebook gfx card.
