Congrats!

I hammered that interval with P-1, P+1, and ECM (not all results reported, but P-1 was reported all) till my keyboard was hurting ...

Do you know roughly how much ECM you did? Wondering if I should just move to t30 bounds straight away

Looking to the full stats, with ECM history turned ON, (here), I think you should! It may take longer per candidate, and it may take longer to churn ALL the range, but IF there are still 11 factors there to be found under 30-35 digits, and your intention is to stop after founding them, then you may get luckier with higher ECM boundaries.

You seemed to have given Prime95 very little memory. If my guess is correct, you gave no more than 3GB to Prime95, so even v30.8 could not help.

This is probably the largest factor found using the P-1 method. Congratulations.

Not even close. It just misses out on the all-time top 10.
It's 2nd place for GIMPS, as you would find out if you read a bit further back in this thread.

And yes, congrats George!

I didn't tell it anything specific. It just runs when I start it. I don't remember ever having to manually do anything with the program. If I did, it was a long time ago.
