force_turbo sets warranty bit, but improves performance.
Most Pi's handle this fine (I've got about 10 Pi's, and all handle this except an early one with Hynix memory which needs sdram_freq=500). You need a decent power supply.
The main issue is possible sdcard corruption, which the USB install avoids.
I haven't has a crash running xbmc in months, so yes it is stable.
With this overclock and a USB install my Pi is faster than my Apple TV2 and iPad 3 for most operations.
I'm currently just using
arm_freq=900
core_freq=333
sdram_freq=450
Is there likely to be a major difference bumping it up to your settings? I'd probably leave the force_turbo=1 out, just because this is for my brother and whilst I want it to be smooth, I also want it to be stable and last as long as possible
Is it necessary to use over_voltage=6 with your settings or will it work, just not as fast, without that (and without force_turbo=1)?
I've been having a bit of remote lag (i.e. not always responding to commands), ghost remote presses, where it goes into a loop as if a key is being held down until I press a button a couple of times and odd freezes/reboots. I had a several minute freeze, I actually went and did something else as I got bored waiting, when I did Remove Source on a folder in Pictures and then later had a reboot going into Pictures. I was getting messages about the server not being available, which it wasn't as I was testing the Pi elsewhere, when deleting the folders so maybe that had something to do with it (when it restarted it said something like "Remote Server connection failed" as well). Had several reboots yesterday every time I tried to watch a channel with MediaPortal PVR and then had some more reboots just when selecting a folder in Movies or Music (but that may have been connected to having the MP PVR plugin enabled). The PVR was working much better this morning, with only one reboot when starting a channel and browsing Moives or Music seems to be OK now.
So I'm wondering if a better overclock might help reduce some of these problems?
I'm using a class 10 SD and a decent USB stick and have a hub powered separately from the Pi (using a 12v PSU into a 5v BEC like this
https://dx.com/p/hobbywing-5v-6v-3a-swit...ubec-15149 ) that only has the remote receiver connected (although I plan to plug in a wired keyboard and sometimes a media USB stick).
