I am quitting K=850612425, tested from 10k to 275965k with only 100 primes 2 of which were reportable.

k=1785
 
A file with k=1785 values in the 361-400k range sieved to 386bn was kindly provided by Flatlander. The file was checked by Battlemaxx (L148) and John (L140) but they found no primes although 1785 looked promising since Flatlander found 7 primes in the 200-361k range.

I suffered a setback, I just bought a new box and 3 weeks later the hard drive crashed, its going to be replaced by dell, but for my k=1222853775, I lost all testing and sieve file from n=10k to 250k, I think my testing was at approx. 176K. My second box is still testing 250k to 300k.
Should I sieve & test from my last prime or start at 175k. All of the llrresults are gone also.

Sorry to hear that :sad: Recently they are putting trash components in their ready-made boxes :yucky: , that's the only way to have some profit while keeping low prices. Just say no to those $499 or similar offers. That's why it's much better to build your own machine if you can, you don't need a lot of technical knowledge, but you need time to explore the web and find what's currently [I]the best bang for buck[/I].:wink:

You can continue from [I]k[/I] you think was checked most recently, 176k in your case. We don't collect result files from "choose your own k", so no problems there.

And finally congrats on your latest prime, from the same [I]k [/I]:smile: Bad news are often interlaced with good news.:cool:
