I'm still loitering but gave up crunching when electricity prices doubled and we're getting another 20% hit next week so doesn't look like I'll be starting up again any time soon.

Sorry, can't help with the face-to-face but I'll say hello anyway as it's a bit quiet in here.

Temperature problems.

The other (and free) option is to turn off AMD's Precision Boost in the BIOS. This will dramatically reduce power usage and CPU temperature at the cost of performance. I would start here and see if things are to your liking before changing out any components.
+1 on this. You'll see a large decrease in temperatures but not much decrease in performance as perversely the extra voltage it pushes in PBO actually decreases performance due to the temperature increase.

Thermal Stress?, Easy fix

Thanks I was kind of hoping for a better solution. I'll give it a try over the weekend with my buddy and see how it goes.
I also tried different types of multi-threading on PPS-LLR Mega and found that running 1 tasks per thread and leaving 1 thread opened yielded the best results so far (100 min per task, 11/12 threads used), compared to running 12 tasks on 12 threads (120 minutes per task). Putting more than 1 thread to a task hasn't helped for that project. If anyone has any other suggestions of optimizing PPS-LLR I'd love to here them. I want to try leaving 2 threads/1core unassigned and see if that helps even more.
I dont have much experience in this field and idk how an AMD processor differs in performance to a lot of the information I read in the forums which I assume is mostly Intel based. If anyone has some general pointers for AMD Ryzen, please share them here.
you should run around 45mins/task if you run 6 at a time. As Grebuloner says, you have to think of the 3600x as 2 3-core processors (each group of 3 is called a CCX) for tasks up to around 2M fft size and then a 6-core over that.
Because of the processor architecure it helps to lock tasks to the same cores as windows likes to move them around which is relatively slow when it moves something from one ccx to the other.

Far better to switch the more aggressive boosting off in bios. You'll find it will still boost to nearly 4GHz but without all the added heat.

Number crunching :
2 tasks of 10 cores running simulantiously
(Message 150402)

These two numbers should be about the same, however when tasks are "running" but not "processing" it will result in what you see is happening to your tasks.
cpu time ~= runtime * cores used.
Now that LLR2 has been implemented there is far less incentive to run many threads for any given task...
This is so wrong it's not funny. Please go and read some of the multithreading topics.

And I am using the maximum capabilities of this system, hyperthreading and 2 gpu's.
So I can run 10 "cores" in whatever fashion BOINC needs.
With LLR you're actually slowing things down substantially by doing that.
eg your SGS tasks you're running 2 every 10 minues. You should be able to run 8 in that time.

There's over 2000 timed-out tasks and 0 valid tasks. Just clueless.

LLR -> Jade.
only ~100M to go to get to sapphire, see you in a year or so.

He's still going. Currently has somehow claimed 3000 tasks to sit on.
