Dreadlockyx Posted August 14, 2012 Share Posted August 14, 2012 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. Anyone else interested ? Quote Link to comment Share on other sites More sharing options...
Mafio Posted August 14, 2012 Share Posted August 14, 2012 you lucky man. here in Italy is quite difficult to get one, waiting time is much higher than 1 month... tell us if it likes cold. Quote Link to comment Share on other sites More sharing options...

just_nuke_em Posted January 27, 2013 Share Posted January 27, 2013 Will the Pi run any of the typical benches though? Quote Link to comment Share on other sites More sharing options...
GENiEBEN Posted January 27, 2013 Share Posted January 27, 2013 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 Quote Link to comment Share on other sites More sharing options...
Dreadlockyx Posted January 28, 2013 Author Share Posted January 28, 2013 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"). Quote Link to comment Share on other sites More sharing options...
richba5tard Posted January 28, 2013 Share Posted January 28, 2013 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 Quote Link to comment Share on other sites More sharing options...
Bobnova Posted January 28, 2013 Share Posted January 28, 2013 I have a Pi. I'll see if I can find time to download/run that. Quote Link to comment Share on other sites More sharing options...
just_nuke_em Posted January 29, 2013 Share Posted January 29, 2013 (edited) (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. Edited January 29, 2013 by just_nuke_em Quote Link to comment Share on other sites More sharing options...
Bobnova Posted January 29, 2013 Share Posted January 29, 2013 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. Quote Link to comment Share on other sites More sharing options...
BeepBeep2 Posted January 29, 2013 Share Posted January 29, 2013 I'd rather overclock one of these http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135341370451 Quote Link to comment Share on other sites More sharing options...

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

richba5tard Posted January 30, 2013 Share Posted January 30, 2013 First ever non x86 submission on HWBOT. Dennis's Raspberry Pi: http://hwbot.org/submission/2350613_devroush_hwbotprime_arm1176_s_2h_39min_19sec_5ms 2h40min , it takes 30sec on a stock i7.

Bobnova Posted January 30, 2013 Share Posted January 30, 2013 Getting java going on the Pi has defeated me for the moment. Grr. Quote Link to comment Share on other sites More sharing options...
richba5tard Posted January 30, 2013 Share Posted January 30, 2013 Depending on which OS you have chosen for your pi installing java may be incredibly easy (sudo apt-get install java) or very hard. http://www.raspberrypi.org/downloads Quote Link to comment Share on other sites More sharing options...

Should work though. I'll try tomorrow, thanks. 1M has been much faster with Python if I'm not wrong, so that may be an option if this platform gains success in the overclocking community (just an advice).

I'll spend some more time on it when I get a chance. Quote Link to comment Share on other sites More sharing options...

Bobnova Posted January 30, 2013 Share Posted January 30, 2013 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 Maybe I can do it blind. Quote Link to comment Share on other sites More sharing options...
xsuperbgx Posted January 31, 2013 Share Posted January 31, 2013 Will this be able to run on android phones too? Would be cool if phone cpu's could be benched and listed on hwbot too. Quote Link to comment Share on other sites More sharing options...
Massman Posted January 31, 2013 Share Posted January 31, 2013 I think so, yes. At least - worked on mine! Quote Link to comment Share on other sites More sharing options...
Bobnova Posted January 31, 2013 Share Posted January 31, 2013 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. Quote Link to comment Share on other sites More sharing options...
