scope burped...
« on: March 11, 2016, 07:50:47 am »
Hi all!

My HP54510 froze today.    Just stopped responding to keyboard or updating waveform.   Video DMA was still churning away though - it took a few seconds to realize what had happened.  First power cycle, no happy little "Chirp" , no screen.  Second power cycle, up and running!  Whatzit mean?   It passes all POST's, and its fan is blowing air fine.

Whenever a bizarre problem happens in any sort of computer or computerized systems, I first check its RAM. Form my experience, RAM is the mother of Satan in all computer systems.

Satan itself is the dodgy PSU imho

I agree.It can be memory.
Thank You, for all earth.

I have more memory bugs than power failures. Probably not in your country, but in China, almost every single Kingston memory stick is fake and is only fully compatible with AMD processors, they can seldom crash Intel platforms. I can almost fix all bizarre computer problems by just swap in another set of memory stick. Even other genuine memory sticks are not guaranteed not to corrupt data, especially when they get old. Memory chips do wear out over years of operation. I did experiments on memory chips at elevated voltage, frequency and temperature as I overclocked them (a very good brand, genuine pair of DDR module). It turns out over this accelerated aging test, they do show some degree of irrecoverable aging, and the symptom is increased date corruption rate. Keep in mind I only increased a tiny bit of voltage and ~20% frequency, and despite not sitting at room temperature, the RAM modules are not that hot. They died within a year, which is only 20% of their rated lifetime.

As a result, I use only ECC sticks in my production workstations now.
