No problem running about 60 RB's with 333MhzI'm curious to hear from anyone who is running overclocked rb532 boards (in particular at 333MHz) and if they've had in stability issues with them? I haven't really seen any complaints at all with doing this, but have not run any production boards at this speed yet. Anyone care to post their experiences?
From de routerboard manual:What is the official procedure to switch the default frequency to 330/333? Mine always reverts back to 264/266.
Changing CPU Frequency
By default, the RouterBOARD 500 series boards are equipped with 266MHz processors, which may be
overclocked to 333MHz with a varying degree of success (no guarantees). The boards that are tested to
work on 400MHz must be especially ordered, and our ability to provide them, as well as schedule depends
on the demand for this factory option.
The bootloader is made so that you must first try a different frequency before it could be set permanently,
and if you do not apply a frequency permanently, it would fall back to the previous setting on the next power
cycle. It is still possible, however, that the board is not working properly on the frequency you've applied, so
the default (266MHz) CPU frequency can be restored. To do that, power the board with the S1 button
pressed, then unplug the power, and when you will turn the board on again, it will have CPU frequency set to
266MHz temporarily, so you will have to apply that frequency by issuing the keep cpu frequency command
in the loader configuration prompt.
I think you can repeat the first line twice, and then keep-frequency and you don't even need to reboot ...
The RC32434 is guaranteed in an ambient temperature range of 0°I wonder what the temp threshold is on these at 330MHz.
I use small self-adhesive heatsinks on overclocked RB's too. I thought I was just being paranoid; I don't know if they make a lot of difference however nothing has crashed as of yet. Any other opinions?For good measure, since it gets hot here in the summers, I buy "ramsinks" from newegg.com that come with self-stick thermal pads and slap those on the RB CPU. Just a little extra measure of comfort, the downside being that you can't use the CF slot if you put a heatsink on the cpu.
