    As RFGuy stated, just make sure to join our team and you are good. All BOINC projects are [H]ard|OCP except WCG which is HardOCP.

    To be fair, most of those credits went to my 2 previous teams, Ultimate Chaos and U.S. Army. I've been a member of Ultimate Chaos since 2000 for other distributive computing projects. I'm was nearly the last member there doing anything, so it wasn't much of a team. I left that to join U.S. Army, thinking it would be a fun community, but it's dead too. So now I'm here, and I'm here to stay... as long as you guys don't go anywhere. You all seem like a fun bunch.

    Also, my heart is in PrimeGrid. I won't be doing anything but that project.

    Good to have you anyways. We hit a lot of projects through the year. Last few years we have focused a large bit on Formula-Boinc. This year we are in League 1 and will have some heavy competition. We also heavily hit the Pentathlon in May. The rest we just fit in between those challenges as we can. November and December is mostly dedicated to WCG. So, don't get discouraged if you are the only one hitting PG serious on some of the challenges. We just have too many projects to hit and PG has a ton of challenges.

    Okay Gilthanis, that is good to know. Thank you for explaining that, as I had no idea of the intricacies of this team. Very glad to hear it's well developed.

    I have ~20 more WUs that should finish before the end of the challenge, so we should pass them, I think.

    Thanks! Now that I know I can run PG LLR work on my TR rigs without CPU overheating issues, I will probably be an even stronger presence in the PG challenges going forward. That means the team should do even better next time. :D

    Funny you mention that. I had the same problem with my one and only 9900k overheating up until this weekend. Turned out to be a bad H115i. I went out and got a new NZXT Kraken from Microcenter, and immediately went from thermal throttling at 3.6Ghz to 55C at 4.7Ghz Prime95 small FTTs. So the whole freaking time I thought I dorked the 7700k when I delidded it. Turned out it was a bad cooler. Funny too, because my temps went crazy about the time I delidded, so I didn't even think it was my cooler. I must have knocked some corrosion loose inside the loop when I was in there messing around with it.

    Well... February only has the one challenge on the books. So, a whole month of finding primes. The good news is that you can win special badges if you are really lucky...lol.

    RFGuy,
    Looks like you're knocking out some serious LLR tasks for the Tour de Primes. Did you know what you have been the double checker for 4 primes?!?! That makes you 3rd place for 1st loser! WTF man?! We need to get you finding primes and being 1st on some of those winning WUs!!
    I'm sure you know this, but I just need to verify, as that's what's in my blood. Don't cache WUs. If they sit on your system not being crunched, that gives others a chance to be 1st for that work unit. There are tips on how to keep only one WU in your task cache for each CPU/GPU you are running.
    Also make sure you have the <report_results_immediately/> in your app_config.xml file (See below). That keeps them from sitting around on your system even tho they are complete, and having someone else get 1st on that WU.
    <app>
    <name>llrXXX</name>
    <fraction_done_exact/>
    <report_results_immediately/>
    <max_concurrent>1</max_concurrent>
    </app>
    <app_version>
    <app_name>llrXXX</app_name>
    <cmdline>-t 8</cmdline>
    <avg_ncpus>8</avg_ncpus>
    </app_version>

    I'm not trying to insult your intelligence if you already know this. I'd rather be safe than sorry as I just hate to see a team member be wingman on 4 freaking primes in such a short amount of time if it can be prevented with simple client tuning. :)
    And hopefully some of this information might help someone else.

    By the way. I know I'm not going to get any primes during this event, so I'm living vicariously through you!! Do me proud!!

    Thanks for the advice, although I was already doing pretty much everything you suggested. I did have a larger cache than I should have, so I have now lowered it to just .1 day on all of my machines. I may look into going all the way down to only one WU in cache at a time, but not sure I'm quite that dedicated to prime finding. That said, it definitely would have been nice to be first on those four primes I double-checked.

    Anyway, given the amount of resources I am now throwing at this competition, it is just a matter of time before I find some primes first. I think the smaller caches will help, so thanks for the tip!

    Congrats RFGuy! You got your first 2019 Tour de Primes Prime, a GFN-16!! I feel like a winner already... living vicariously though you.

    Thanks!

    Now I’ve gotten greedy and have switched over to the Genefer 17 Mega tasks on my GPUs, in order to try to find a Mega-Prime.

    That's exactly the tactic I would employ. Problem is I'm not finding anything
