Test Failure, just need some general advice

[creyldor]

Hi There,

I've been using memtest86 a long time and it has helped me to identify bad ram out the box and other hardware issues. However, after 7 years I got a couple of lockups then a blue screen in windows with the stop code MEMORY_ERROR or similar.

I fired up the latest memtest86 and low and behold I have errors reported.

I am 99.9 per cent sure this is a ram issue, although after 7 years of operation I am surprised the ram suddenly went bad. My PSU and CPU all seem to be operating in normal parameters so at this point, I am hoping its the memory at fault and not the motherboard.

I have already pulled the trigger on new ram anyway but I'm really just looking to see what others thought of the results, the html results state the following:

A total number of errors about 524 over 4 passes pretty sure its memory, the computer seems alright in operation but it's just a matter of time I reckon.

Thoughts?

Looks like bad RAM.

[creyldor]

Yup thought so,

Got the replacement through from the manufacturer today and ran a test with no issues, old ram has a lifetime guarantee lets see if they honour it.

Not sure why it went bad, after all has no moving parts and my case sits at about 47 degrees (celcius) so its not heat

Ahh well will have to chalk that up to experience.
