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...
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...
Dreadlockyx Posted January 29, 2013 Author Share Posted January 29, 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 How do I use the source files ? Can't figure out how to include hwbot libraries. Forgive my noob skills in programming. 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 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: http://s7.postimage.org/51b7su0ne/WP_001113.jpg Front side http://s14.postimage.org/6hdl1hpf3/WP_001113_2.jpg Front side, labelled http://s7.postimage.org/hv99m6e2y/WP_001114.jpg Front side, core area http://s7.postimage.org/fryueiea2/WP_001115.jpg Front side, USB controller area http://s7.postimage.org/gb3xns5oq/WP_001112.jpg Back side 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. 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. What crystal are you talking about ? I have no idea what it may be. I'd rather overclock one of these http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135341370451 Too expensive.

Bobnova Posted January 29, 2013 Share Posted January 29, 2013 It's on the bottom of the board, right under the CPU. Silver thing with a brass border. Quote Link to comment Share on other sites More sharing options...
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...
Dreadlockyx Posted January 30, 2013 Author Share Posted January 30, 2013 Compiled version:http://downloads.hwbot.org/downloads/hwbotprime.zip Tested in win7/8, mac osx, linux ubuntu, but not yet on ARM. 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).

Bobnova 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 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. 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...

Bobnova Posted January 31, 2013 Share Posted January 31, 2013 (edited) I sat down and explained WTF java was to it in very small words. Open whatever it was, to be specific.

I canceled after 10m or so and played with the OCing bits, ran it again 5m ago. The cpuid error makes me wonder if it's hung rather than just taking a while.

Bobnova Posted January 31, 2013 Share Posted January 31, 2013 Far as I can tell it calculates forever. Left it overnight, no change come morning. I'll try another OS at some point here. Quote Link to comment Share on other sites More sharing options...
