03:48 <wpwrak> (omap unreliable) naw, don't know of that. they're very complex, though.

03:49 <wpwrak> (off-topic) sometimes, the universe just hates you: http://avherald.com/h?article=48293b2a&opt=0

04:17 <DocScrutinizer05> ((stop working after 4 years)) yes, when you overclock them

04:18 <DocScrutinizer05> the chips have 100,000h at OP1 to 4, and only some15,000h at OP5. Going to OP5++ will *drastically* reduce chip lifetime

04:18 <infobot> i heard omap-oc is http://mg.pov.lt/maemo-irclog/%23maemo.2010-08-01.log.html#t2010-08-01T22:16:05 read that!, or and this http://mg.pov.lt/maemo-irclog/%23maemo.2011-03-11.log.html#t2011-03-11T03:04:11

04:25 <DocScrutinizer05> also design flaws in thermal management can cause the chip to constantly operate beyond max temeprature rating, which also reduces lifespan extremely

04:26 <DocScrutinizer05> and we're talking about 10^x here for factor of lifespan shortening

04:27 <DocScrutinizer05> with x something maybe like (°C above linit) / 10

04:30 <DocScrutinizer05> ~wiki electromigration

04:30 <infobot> At http://en.wikipedia.org/wiki/Electromigration (URL), Wikipedia explains: "{{More footnotes|date=July 2010}} 'Electromigration' is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is important in applications where high direct current densities are used, such as in microelectronics and related structures. As the structure ...

04:36 <DocScrutinizer05> feel free to work through the formulas in there, and correct my above guesstimation of 10^x

04:39 <DocScrutinizer05> anyway when lifespan drops for 500MHz->600MHz by factor 5 from 100k to 22k hours. then it drops for 600->700 *at least* to 22kh/5 = 4.4kh, and for 700->800 to 4.4kh/5 = <1000 hours

04:40 <DocScrutinizer05> and I expect the factor to increase rather than stay constant, like /5 /7 /10 ...

04:44 <DocScrutinizer05> and yes, OMAP4 is flawed. At least that's what I heard when working for a customer who supported customers using those critters

04:45 <DocScrutinizer05> there seem to be SiErr that are "WONT FIX in OMAP4. Fixed in OMAP5"

04:45 <DocScrutinizer05> not related to lifespan though, but who knows what else is in there that I never heard about

04:47 <DocScrutinizer05> (SiErr in tickets opened while testing on TI Blaze)

07:33 <eintopf> oh thanks

07:34 <eintopf> i had this night the biggest stomach pains forever. that wasnt funny

07:40 <eintopf> so i think neo900 is prepared for long time lifing

07:44 <wpwrak> nice quote from xkcd: "the self-driving car project we launched by accident [...]"

07:50 <eintopf> hi wpwrak
