The Tiamat kernel has been updated to make it possible to overclock the Motorola Xoom further than ever before. Version 1.4.4 will let you push your Xoom from 1GHz to 1.2GHz, 1.408GHz, 1.504GHz, 1.6GHz, and even 1.7GHz. The Xoom was pushed to 1.5GHz back in February 2011, and only recently overclockers managed to achieve 1.6GHz and 1.7GHz.
Pushing your device to the limits doesn't work for everybody, but it is supposed to be pretty stable. If you manage to pull it off, you will see 70 MFLOPS in Linpack, 1480ms runs in SunSpider, and Quadrant scores approaching 5,000.
You can grab the source for all the Tiamat kernels over at GitHub. For more details and instructions for this particular overclock, head over to the XDA Developers forums. Remember that you are doing these modifications at your own risk and if something breaks, you can only blame yourself.
The Motorola Xoom ships with Android 3.0, but has an Android 3.1 update available for it, (both codenamed Honeycomb) running on Nvidia's Tegra 2 processor, 1GB of DDR2 RAM, 32GB of onboard storage (expandable via SD), a 2-megapixel camera on the front, a 5-megapixel camera with dual LED flash on the back, a micro USB 2.0 port, HDMI out, 802.11b/g/n Wi-Fi, as well as Bluetooth 2.1 + EDR. The 10.1-inch tablet has a 1280x800 display resolution. Battery life is said to peak at about 10 hours of video playback. The device will launch in Q1 2011 with 3G functionality, later upgradeable to LTE 4G, and will launch with a LTE 4G model in Q2.
