Ref -<The most serious source of these Alpha particles is the lead in the C4 solder balls>

Thanks for the info. I find it amusing that chip vendors try to blame all soft error problems on cosmic rays. By blaming cosmic rays they absolve themselves from the blame for not cleaning up the contaminants in chip packaging.

Too bad Sun did an inadequate job of characterizing the alpha particle susceptibility of their design. From your post I infer that the L2 cache for Sun is off chip. So adding ECC to that, can take 6 months, or else they have to find low error rate SRAMs.

According to the media only Intel chips had problems ! Sun is tryiing to break Intel's monopoly !

Ref -< Incredibly enough, things are so bad at IBM that they will be supplying Sun with the new 16MB SRAM memory chips they will be using to make these mirrored memory modules to fix the problem. >

I am confused by the above statement. Did I hear you say that IBM is using Sun Servers, which are misbehaving , and consequently IBM will supply its Low Error Rate Chips to Sun, so that the systems at IBM can be fixed ? What did I miss ?

Thanks

YWY Incredibly enough, things are so bad at IBM that they will be supplying Sun with the new 16MB SRAM memory chips they will be using to make these mirrored memory modules to fix the problem.

The new IBM: they'll sell anything to anyone, including to their toughest competitor.
