Do you have reference to recent papers with experimental data about non
ECC memory errors? It should be fairly easy to do

Maybe this provides some information:

http://en.wikipedia.org/wiki/ECC_memory#Problem_background

"Work published between 2007 and 2009 showed widely varying error rates with over 7 orders of magnitude difference, ranging from 10−10−10−17 error/bit·h, roughly one bit error, per hour, per gigabyte of memory to one bit error, per century, per gigabyte of memory.[2][4][5] A very large-scale study based on Google's very large number of servers was presented at the SIGMETRICS/Performance’09 conference.[4] The actual error rate found was several orders of magnitude higher than previous small-scale or laboratory studies, with 25,000 to 70,000 errors per billion device hours per megabit (about 3–10×10−9 error/bit·h), and more than 8% of DIMM memory modules affected by errors per year."
