Fix the sluggish performance of the Q1U made by Samsung running Vista
The Q1U with the factory settings is very unresponsive, and we think that is due to the very slow hard drive the unit is equipped with.
The quickest way of improving performance from our experience, is to upgrade to a 2GB memory module from the current 1GB memory module that is pre-installed on your device by default. Hugo Ortega has made a nice video (available at http://ubertablet.blogspot.com/2007/06/how-to-upgrade-q1-ultra-to-2gb-ram.html ) that shows how to open up the device and install the memory modules. We are using KINGSTON modules part number KVR667D2S5/2G, and have had a good experience with them so far.
Whilst upgrading the memory helps the system performance, it is still very unresponsive each time a hard disk intensive task starts. For this reason we recommend disabling Prefetch and SuperFetch. To do this:
- Open the Start Menu (Click/Press on the ‘Start’ Button)
- Type regedit in the “Start Search” text box and press return (or press/click on the program ‘regedit’ that’s listed from the search).
- In the tree shown below go to the node:
- On the right side of the table partition, where the files of the folder are listed, double click on EnableSuperfetch, enter 0 in the box (‘Value data’ field) and click OK
- On the right side of the table partition, where the files of the folder are listed, double click on EnablePrefetcher, enter 0 in the box (‘Value data’ field) and click OK
- Close the ‘regedit’ editor window.
In case you want to undo or reverse the solution, just follow the same procedures as above, but enter 3 for both EnableSuperfetch and EnablePrefetcher.
Disabling some of the graphical eye candy helps as well:
- Click on the Start Windows (Windows Icon) button in the taskbar
- Click on Control Panel
- Click on the Classic View link on the left hand side. (If it isn’t already in ‘Classic View’ mode already)
- Click on the System Icon.
- Click on the Advanced system settings link on the left hand side (in the ‘Tasks’ section).
- Click on the Settings… button in the Performance panel
- Select the Custom option and select only the following items and uncheck the others.
- Enable desktop composition
- Enable transparent glass
- Show preview and filters in folders
- Show thumbnails instead of icons
- Show translucent selection rectangle
- Smooth edge on screen fonts
- Use visual styles on windows and buttons
- Close all windows
Just to be sure that the operating system uses the new settings, reboot the device.
Now the device will feel more responsive (feel snappier), and it only freezes when loading an application or if it does some other hard disk intensive process.
