Re: Images getting corrupted in Lightroom 4.2

I am not an apple-boy.

Testing memory: http://macosx.com/forums/howto-faqs/299888-use-apple-hardware-test-oth er-diagnostics-test-hardware.html

Memory modules should be treated in pairs (inserted, extracted, changed)

1. Test all (4) modules
2. if OK - I do not know
3. if FAIL - problem diagnosed
4. Extract 2 memory modules
   1. I do not know if memory slots are color -coded, if YES pull off modules from the same color slots
   2. In NOT, try 1st & 3rd - it should be a pair
5. Repeat test
   1. if OK, send extracted to distriburor as fauly, end
   2. if FAIL, extract other 2 and insert extracted in previous places
6. Repeat test
   1. if OK, send extracted ... (2nd & 4th)
   2. if FAIL send all modulest

And - maybe the problem is in dirt on contacts, so extract, clean (as lense) re-insert, repeat test.

Happy testing (not very exciting, but time-consuming)
