There will be no flaming on 94lt1's and my watches!
Your questions are relevant and worthy of explanation.
I'll go last to first.
3) The TI OMAP 4430 used in the RAZR is slightly different than the one described in the link 94lt1 provided, but essentially the same in that it is exactly the same physical chip, manufactured in the same labs, and may even be off the same slab as one that is described in that article. The difference is that the chip in our RAZR is actually clocked at 1.2Ghz, rather than the standard rated 1.0Ghz, which is a significant improvement. The way this was accomplished is that once manufacturing is completed the manufacturer will put the chips through a long burn-in (upwards of 24 hours or more), testing every feature and instruction it is designed to perform in sequence, to determine if the chip is functioning normally in every way.
While testing, they push the chips to higher and higher clock speeds and monitor their temperatures. Based on internal resistance levels of individual transistors on the boards as the speed is increased up to and above rated clock speed (overclocked), the temperature will either rise quickly (which could identify a bad chip), rise nominally and within normal ranges (which would be sent to market), or rise slightly (which identifies a chip with exceptional performance aspects).
Also stability is monitored, so chips that begin to show problems performing expected functions at or below rated speed will be deemed unsuitable for distribution and may actually either be disposed of or sold with a much lower clock speed rating as "Power Saver" or some other moniker, whereas those that perform at or above expected ranges will be distributed accordingly. It's those chips that exceed typical performance, both in clock speed and stability at higher speeds that are then marked "Turbo" by Texas Instruments and sold with ratings that are higher than design specifications.
It has been said that the TI 4430 OMAP in the Droid RAZR and RAZR MAXX is "Overclocked" to 1.2Ghz, and although technically when compared to its design rating is true, based on its tested performance the manufacturer has certified it to run at that speed so by way of manufacturer's warranty it is not actually considered "Overclocked".
2) Regarding the Droid RAZR XT912 (and it's baby brother MAXX), I've been unable to find any mention of BSI (Backside Sensor Illumination), except on this site
AnandTech - Motorola Droid RAZR Review - A Better Clad Bionic. Even Motorola itself doesn't mention the BSI on the XT912, and the most well respected review sites also make no mention of the feature on the XT912, however I did find mention on the XT910 (*overseas model*) of BSI-2 for the camera, and although it has been speculated that the RAZR has the same camera as the Bionic, the
OmniVision OV8820 8 MP CMOS, I can't confirm that either, and also can't confirm that model camera of having BSI. Perhaps somebody else can find definitive information that can either confirm or deny.
1) USB On-The-Go has also been proven to work on the XT910...

...with a standard USB Host cable, but again sadly on the XT912 although it can work you have to jump through some hoops.
From XDA Develpoers (

The USBOTG cable HAS TO give power to the RAZR and to the devices you're connecting to it, otherwise the RAZR won't recognize the Dock Connected status.
Be sure your AC power is 5V with at least 1A, otherwise there won't be enough amperage for RAZR and the connected device and since the RAZR has got the priority, you'll only charge the device's battery and your connected USB device won't have the necessary power for working correctly.
ROOT is not needed for OTG USBHost operation as the device has been configured by Moto to work in USBHost Mode.
When you connect an external pendrive, the device will automatically create a device node and will automatically mount the connected pendrive/USBHDD in a directory created in /mnt.
I've successfully connected all the device I was able to use on ATRIX, including keyboards, mouses, an 8GB PenDrive and a 500GB external HDD.
Also from XDA (http://forum.xda-developers.com/showpost.php?p=19772144&postcount=24), and finally (

Cheers! :biggrin:
