This appears to be a stable overclock for my pi 3:


dtparam=sd_overclock=100
arm_freq=1275
over_voltage=4
sdram_freq=575
sdram_schmoo=0x02000020
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4
core_freq=500
v3d_freq=500
h264_freq=333
gpu_mem=256

Edit,
I have seen Milhouses and popcornmix's overclocking settings so going to run with these
arm_freq=1300
gpu_freq=500
over_voltage=4
core_freq=500
sdram_freq=580
over_voltage_sdram=5
sdram_schmoo=0x02000020
force_turbo=1

So is it worth overclocking the Rp13?

Whats runs better when its overclocked? I understand that its quite fast running on normal settings..?

There are some memory tweaks for gpu and cpu but I think openelec or osmc set them as default.
Are the settings you posted "nick w", not void warranty? How long has the pi3 been running on those settings?
Pi3 only came out in February. I want mine to last like my pi1/2

Hi

I run the Milhouse builds and use the Pi in my cinema room to play all my ocntent so even before i tested it i overclocked it. i have a pi2 in the lounge and browsing menus it was a bit luggish. i have now overclocked that and it runs alot nicer and smoother.

all my rPi's run 24/7

Havent had any issues other than the rPi3 running hot due to having a slim line case which prevent airflow.

yes, force_turbo=1 does void the warrenty i beleive. but at £27, its no biggie if it goes pop. They are made to be pushed and dabbled with

I'm running OpenELEC on a RPi3, do I just open the config.txt and paste this in at the end.

No. Check what's already enabled as you don't want to enable a setting twice.

I see further up in the config.txt file that gpu_mem=128 is already there. So its probably safe to say that I should delete one and then change the other to gpu me=256. Big Grin

If a setting is listed twice, the latter one has precedence, so you don't have to delete earlier ones (although it may be less confusing if you do).
The bigger issue is that someone else's overclock setting may not work on your pi.

Overclocking is not guaranteed and often needs a certain amount of tweaking.
Backup before applying (especially if using the aggressive dtparam=sd_overclock=100).

is it possible in config.txt to have overclock settings specific to RPi2 and RPi3 in the same file?
(basically so I can move the SD card between RPi2 and RPi3 without stripping settings)

I think I saw something about that on new installations. I've been running my *elec RPi2 build for many months and don't see a separate section for RPi2/3

According to https://www.raspberrypi.org/documentatio...fig-txt.md you can filter config.txt settings by Pi models. It doesn't mention a Pi3 option - but I expect that [ALL], [pi1], [pi2] and probably [pi3] will work to allow model-specific overclocks on the same SD card.

Yes.
Code:
[pi1]
arm_freq=1000
[pi2]
arm_freq=1100
[pi3]
arm_freq=1300
Would work.
