#1 Computation errors

Post by CycloneRanger »

Of a sudden, I've begun dumping Collatz results by the bitbucketful due to "computation error". Any one else having that problem, or any idea of what I might do to eliminate this problem?

I'm running BOINC version 7.22.33(x64)

BOINC is attempting to read memory that it should not, hence the access violation.

This could be down to many things:

Hardware error, bad memory for example
Overheating
registry corruption
driver corruption


In a rough debug order:

Check your temps, clean the dust filters, etc.
Disable any overclock you have on both your CPU and GPUs
Do a hardware reboot (cold reboot)
Run a memory test

Do a reset on the project, check any custom config files
Removing and reinstall BOINC for the current stable build
Remove and replace your GPU drivers
If that all fails, delete Windows and reinstall

I often use a Linux Live CD to test things out. If you have one you can quickly rule out hardware troubles.
