Thanks for the info (I did not find a reservation or status-update for the k with a quick search). I was planning on putting one core to crunch one low-weight, already sieved, low-n k, but perhaps I'll dedicate also that core on running ECM (stage 1) on F12.

I unreserve the k=9913 then and continue slowly just with 45045. (Maybe http://www.rieselprime.de/ could be updated on k=9913).

edit: on a second thought: I could reserve k=3907 (if it is not also tested to the 3M heights.. It is not complete obvious for me where I should check the reservations)

Did you mentioned this effort in this Forum? If so, please give me a link, so I can insert it on my page. Thanks.

It's not reserved on my pages because FDC is dead for a long time, only primes found by Burt were inserted.

Batalov pointed out by pm that these ks are even. Not sure how this has been missed for this long.

I am pretty certain none match up. The numbers in CRUS have been tested higher anyway.
