Repairing RAM: Component Level
« on: July 29, 2008, 08:20:30 AM »
Meron na bang nakapag repair sa inyo ng RAM component level?

eto kasi yung nangyayari sa akin ngayon...

Memtest Screenshot:



tinitignan ko yung Error bits: 000040000. kung sa binary 1000000000000000000. mukhang may isang bit na palaging nag eerror.

eto yung RAM



I inspected it already and I don't have idea kung ano ang problem, kung sa trace or one of the eight mem modules... I am tempted na to remove the memory modules one by one...

This occurs only around 3 minutes after boot-up... mukhang nagkakaroon ng temp problems...

Any inputs will be highly appreciated. :) :) :)

nakapag repair na kami ng ram. kaso pang pentium 1 ata na ram yun. anyway madami din na IC, signature analysis yung appoarch. Address at data yung tinignan nami. altough naka parallel lahat yun, makikita kung anong pin yung may tama through comparison, dapat kasi magkakaparehas lahat ng address at data line. after ma isolate yung pin, tapos sunod na problem ay pag hanap ng IC, aalamin muna kung ano kalase ng sira based sa ASA, kapag nalama na medyo short ang sira though resistance naman.

sa temp problems, naka encounter na kami na kapag normal temp ok yung device, pag umiinit nag short yung pins nya. so pinainitan namin ng hot air habang nag test para makita at lumabas yung sira.

ewan ko lang kung makaka tulong to.. share lang
