    I've had my trusty aspire 5672 since 2006 and have had relatively few complains with it.

    so far I've successfully upgraded the HDD to 250gb, the Ram to 4gb of OCZ memory and the processor to a 2.14ghz T2600 Merom CPU. All of the upgrades went seamlessly. Windows XP only sees 3gb of RAM but OSX is able to use the full 4gb. I've also replaced the intel wireless card with a dell one for airport support under OSX but i switched back to the intel because it get a better signal.

    Right now I'm dual booting between XP SP3 and OSX 10.5.3. In order to get OSX working right I had to hack the BIOS in order to fix the ACPI tables. If you are running Linux or OSX and having DSDT problems let me know and I can send you a copy of my bios for a permanent OS independent solution.

    After some overheating problems in games after upgrading the CPU I decided to look into undervolting. Using Rightmark CPU Clock Utility I've set the max VID to 1.0000v. I'm sure it would run fine with a min VID lower than .95v but Intel has idiotically capped merom CPU voltages ridiculously high. With a full CPU load the comp runs stable and doesn't go over 80 degrees Celsius. The fan also remains whisper quiet as long as I'm not gaming. I suggest everyone try this out as it will seriously cool down your laptop and help conserve battery power.

    I've also experimented with overclocking the mobility x1600 with ATI Tray Tools. I've safely taken the core clock from 440 to 540 it might go higher but I don't feel safe pushing it any further so i won't tempt myself with further testing. It also seems that the 128mb cards in these laptops use slower memory than their standard 256mb counterparts as the 256mb cards run their memory at 470 stock. 454.5 seems the highest I can push the memory without artifacts. Combined with the lower CPU temps from undervolting, OCing the graphics doesn't seem nearly as dangerous any more.

    curious to hear how others have fared with overclocking and undervolting.

    i'd also like to try and mess with the fan settings in the BIOS to change which temp/speed it runs at. if you have experience with this i'd love to hear from you.

    Discussion of running Mac OS X on non-Apple hardware is against forum rules. It is illegal.

    Thread closed.

    If you have any Undervolting questions. Please post it in the undervolting thread
