I just turned in my result for that (I'm working on triple-checking stuff and just happened to have that one already queued up, just turned in a minute ago).

[QUOTE=Mark Rose;432373]Or [url=http://www.mersenne.org/report_exponent/?exp_lo=38987401&full=1]M38987401[/url], from September.[/QUOTE]

I also predict this one will end up bad news for Bruno.
[URL="http://www.mersenne.org/M37713733"]M37713733[/URL]

The other CPU has a better track record of 24 good, zero bad (lifetime stats)... compared to 79 good, 15 bad for Bruno's. Bummer.

That was my only automated prediction... [URL="http://www.mersenne.org/M40935859"]M40935859[/URL] isn't predictable... the other CPU in that one has 3 good, 1 bad. Who knows... maybe both are wrong. :smile:

*sigh* Time to put that machine down.
A few notes on it might be of interest:
i7-4790K with 2x8GB Corsair Dominator 2400MHz RAM on an Asrock Z97 Fatality Professional Motherboard.
First few results from the machine are always correct (around 3 to 4).
Then DCs turn into mismatches which get confirmed to bad results.
Running memtest shows that the RAM is bad.
Sent RAM for replacement, first results are correct and then it starts to mismatch.

The RAM I replaced I did run initial memtests and it showed no errors. Now it's bad again.
Which makes me think it has to do with the motherboard or the particular CPU.

It's possible it's still the RAM.

Here's a batch of strategic double-checks... these are generated by looking at the lifetime stats of each CPU, and it includes any system with at least 1 bad, zero good, and only one solo-checked exponent left.

I figured we'll never get any better data on whether this machine is trending good or bad, so we might as well check that last solo exponent.

Plus, looking at the lifetime stats for a CPU still gives slightly different data than looking at just one year (or one month) at a time, especially for slow systems that don't turn in that many results.

Enjoy!
