Raspberry Pi OC ?

Recommended Posts

Yes it is possible, but is it worth it ? Will we see LN2 pots on it ?

 

I received two boards so... if one mod fails I can still try another. :D

 

Anyone else interested ?

you lucky man.

here in Italy is quite difficult to get one, waiting time is much higher than 1 month...

Will the Pi run any of the typical benches though?

 

It's ARM so no Windows yet, you can have linux on it but then you'd need the software. So, no :)

There is a Pi benchmark in Java and Python. Python is obviously faster, and can be also ran on any computer.

I'm looking into a voltmod or something (also some kind of a "chip pot").

(also some kind of a "chip pot").

NB pot might work. Though there is a row of pins near the core. Guess it depends on the size of the base. There is that thread about making a NB pot from the copper insert of the Intel stock coolers. That might be small enough.

 

From the looks of it, the core is probably powered from a linear regulator. If it's a fixed one, just pop it off and get an adjustable one. If it's adjustable regulator, find the resistors that set the adj pin.

I expect the main issue will be in keeping the regulator and crystal from coldbugging.

The 19.2MHz crystal right under the core is not going to appreciate Cold at all.

Does anyone have a raspberry pi? We have a beta multiplatform bench in java. Tested on win/linux/mac and works well, both with a gui and in console mode. Normally it should run on a raspberry too if you install an ARM java runtime.

 

github link:

https://github.com/frederikcolardyn/benchbot/tree/master/primebench

 

How do I use the source files ? Can't figure out how to include hwbot libraries. :D

Forgive my noob skills in programming.

I don't have an Intel cooler that I can mod for a small pot, so I'll try something with aluminum foil.

 

Here are some pictures of the board:

EDIT: When using the front GND, results differ from when using the back GND (although it's the same solder point). I don't understand why.

What crystal are you talking about ? I have no idea what it may be.

 

 

Too expensive. :o

Depending on which OS you have chosen for your pi installing java may be incredibly easy (sudo apt-get install java) or very hard.

I'm on Wheezy, Oracle has a walkthrough for it, but it didn't work (apt-get says "wtf is java?"). I'll spend some more time on it when I get a chance.

sudo apt-get install sun-java6-jre

 

Or openjdk :)

I'll give that a shot once I figure out how to get it internets, my only HDMI monitor is a rather long (unwired) distance from my router :D

Maybe I can do it blind.

Got it running! Or at least running as far as estimating processor speed. It's been doing that for maybe five minutes at this point.

I'm SSH'd into the box, don't know if that'd be a possible issue or not.
