Best I could do for now is 1550MHz. I think my usb adapter was having a faulty cable because it fell out or went on when I shake it :P Will try tomorrow with a new cable. With the attached external power, 2.1V is max I can do. http://i.imgur.com/kERCOJxl.jpg http://i.imgur.com/4UlV95Ml.jpg http://i....

Got that now too. Probably going for new record in the weekend If all works well that is.

You can just replace the start.elf while in raspbian?

Maybe a stupid question, but how do I use your file? I'm failry new to linux to be honest.

Nice work. Will try this as soon as I find some time to do it.

Might depend on what battery you intend to use. If it's some sort of LiPo battery it might work, because these have much more power than just an AA nimh cell or something alike. Just make sure the output is in the 1.0-2.0v range ;) But IMO it would be better to use a constant power source and not so...

When I was testing it, I hit the 1500MHz wall with just over 1.8v and was pretty stable at that point. The only thing that would make the system unstable were the RAM, Core and gpu clocks. This benchmark: http://hwbot.org/submission/2510494_rsnubje_hwbot_prime_broadcom_bcm2835_819.02_pps checks the ...

Hi, Since I'm one of the few that actually tried this mod, let me help you with this. See below images(click to enlarge). I highlighted the areas that you need. For your external supply you can use the blue highlighted ground. Just make sure it's a solid supply with not to big of a vdroop. If you ne...

So that should be "current_limit_override=0x5A000020" right? Haven't tried this yet. I've seen some stories about bios_limit but i don't think this applies for the pi.

Is it possible to use processor.ignore_pcc=1 for this? If so, where should I put it on raspbian?

I will check the real frequency, altough I believe it does really run at 1500MHz. Might be worth to try another OS?
Just have to say this, I'm pretty much a noob when it comes to using Linux, so I'm still learning to get along with it.

I will report back when I have checked the real frequency.

Hi there, Currently I'm working on overclocking the Raspberry Pi (B revision) and I managed to get it to 1500MHz with a voltmod which allows me to apply any voltage I want. Getting to 1500Mhz was pretty easy, but even if i go only 1MHz above 1500MHz, it will not boot into OS. I'm pretty sure the ARM...
