Not to belabor the subject, but the badge shown on my account page is still the military style (and hasn't changed FOR EVER :) ). Did these get changed back to the badge types that were initially purposed (and currently show in my signature) and my account just got missed, or did something else get implemented?

Looking at my account the same thing has happened.

DOWNLOAD and INSTALL the most recent BOINC (either the Stable V 7.6.22 or Beta/Test V 7.6.33) Version from for your PC's configuration.

You will NOT loose any work currently downloaded.
Make sure BOINC is not running and Shutdown/Exited completely before installing. A REBOOT of your computer will be needed after installing.

I did more searching in the traces that I took of successful and unsuccessful machines. The machines that were NOT successful had an endpoint IP of for Collatz. The successful Collatz machines talk to an endpoint IP of for Collatz. Why we should get 2 endpoints is beyond me. Whoever is in charge of the Collatz project needs to get us all to point to the latter (and proper) IP address of We will know when that is fixed, as then EVERYTHING will work! (Mic Drop!)

If your computer(s) and or router/gateway finds the 205 address.... it probably has STALE DNS INFO stored in memory.

You should probably shut down BOINC, reboot the PC(s) and then FLUSH the DNS CACHE of your PC and possibly even reboot the router to get correct DNS information.

I also used's CACHE CHECK to see what it return and all their servers world-wide return the same answer (

8) Message boards : Number crunching : Out of Memory errors (Message 23093)
Posted 520 days ago by Dr Who Fan
Have seen the SAME thing on a quite a few Collatz tasks (I run CPU ONLY tasks)in past month. Win 8.1, Win 7 and Win Vista ALL seem to be affected.

Not sure if there is a BUG in the latest Microsoft C++ run times files since the September Windows update (on 9/13/2016) or if it is ONLY Collatz related.

Upon starting it seems they use ALL the CPU resources, gobble up ALL free (RAM) memory & ALL free swap file space Windows has available then crash a second or three later with out of memory error.

On my Nexus 7 tablet (ARMv7 Processor rev 9 (v7l) @1300MHz / Quad-Core) the new tasks (Collatz Sieve) will take approximately 193 HOURS of CPU time running at 100% CPU use.

Due the the battery starting to show it's age I have run the CPU's at aprox aprox 65% of full power, the task I have running now is estimated at aprox 300 hours of total run/computation time.

Some of your tasks are erroring out almost immediately (0.71 Seconds) with "255 (0xff) Unknown error number"
See this one as an example:

BUT you are not the only one having that type of problem with those specific tasks. Seems to be am on-going Collatz PROGRAMMING ISSUE.

Ummmmmm... nope. Same apps, same WUs, and they all ran 100% OK. That was without suspending though. For those having errors, can you try NOT allowing BOINC to suspend and see if it works OK. If so, there may be a bug in the re-start after a checkpoint.

None of my error-ed tasks are a resume from suspend. They all crash within a few minutes of initial start up.

Still seeing high amount of error rates on GPU tasks for Host ID 146029

Almost all are of the "At offset xxxxxxxxx got xxx from the GPU when expecting xxx" type of errors. Where "x" is a variable number.

NOTE TO SLICKER: Like Hal9000 pointed at in a previous post - suspecting these error are related to the Electrical Problems YOUR residence had a few weeks ago.

Yes problem STILL around. Hal, that is what I suspect also - corruption of data and/or other hardware damages from the power surge/lighting strike.

6 more (so far) task for me have crashed since project came back on-line

Seeing the same thing with a few of tasks sent to me & wing mates.
So far only see problems with opencl_nvidia_gpu formatted tasks: Collatz Sieve v1.05 (opencl_nvidia_gpu) Collatz Sieve v1.05 (opencl_nvidia_gpu) Solo Collatz Conjecture v6.04 (opencl_nvidia_gpu) Mini Collatz Conjecture v6.04 (opencl_nvidia_gpu)

Finally got one to complete using the settings Slicker posted.
STILL HAD GPU DRIVER CRASH/RESTART when the task first started and after a task suspend/restart.

At times the CPU usage was up to about 90% but never went below about 80%. The task was sent out with the following parameters > 0.581CPU + 1NV.

Did NOT notice any screen lag, I had to modify my local settings while it ran reserve a FULL CORE to run it to avoid whole system from becoming almost unresponsive.

Interesting side note is that GPU-Z claimed 0% (NO) GPU USE while it was running.

Run Information from BoincTasks:

TASK# 18139359

NOTE FOR Slicker: The way Nvidia implements open_cl you NEED TO RESERVE A FULL CORE for high GPU use. Any way you can modify the Settings on the server so when the task is sent out it RESERVES A FULL CORE on Nvidia GPU's?

So far BOTH of the Sieve tasks I have downloaded crashed almost immediately and also crashed my GPU forcing a restart of the GPU.

Suspect your REAL-TIME Anti-Virus/Anti-Malware (AVG, Norton's, etc) are getting in the way and probably think it's a bad/rogue program.

Posted 1128 days ago by Dr Who Fan
I see that you are currently running a Large Collatz Conjecture... (opencl_amd_gpu) and so far only have Consecutive valid tasks 4.

BOINC is horrible in initially estimating completion times and makes a best guess based on your hardware.

As with any new tasks you never have run before on any project, BOINC will gradually adjust the estimated completion times as you reach the magic number of 11 of those specific tasks run, returned and validated as it "learns your true hardware speed".
