unstable machine

[Greg]

I have been on FAH for about a month. I'm estimating about 50% of my WU have failed with the log reporting "unstable machine". Failure usually after running 2-3 days. I am not running any programs, just surfing the net and I avoid sites where problems might be expected. I do run adaware. Windows 10, intel Pentium, 3 Ghz, build 7.4.4. Any help would be appreciated.

Any OC?

Info about your hardware?

Please post more detail from you log file (How to ...).

We also need more details from your hardware ... laptop ? desktop ? cooling ? ...

I am not sure about how to check temperature, but dropping from full to medium a few weeks ago seemed to help. I am running a desktop machine. Not sure what an "OC" is. I had cut info from my log file around unstable machine crash, but a thunderstorm a few minutes ago caused a shutdown and now that info is gone. Is there a way to back up or scroll up on the log file?

By default the folding client keeps the last 16 log files in a folder within the same location which is shown as the CWD in your section of log file. The file name for the log.txt file is extended with a time stamp.

OC is short hand for overclock.

This may be more info than you need.

I think I've spotted the problem, all units these days are designed to run on 2 or more cpu cores, your WU are trying to run on just 1 core and I think that is the issue. The only way to solve it is to set the folder back to full and make sure its using 2 cores. Since my rigs are currently off I can't remember if moving the slider back to full is enough.

If you are having problems on running on 2 cores I would suggest either memory that starting to fail or a heat issue, it may be worth opening the case and cleaning out the heatsink on the cpu.

As for an OC, it means overclock, setting your CPU/graphics or RAM to run at a faster speed than it was designed to.

Also, you have a Pentium D which is known to generate a lot of heat ... so make sure you've cleaned your fans and heatsinks from dust.
