MJH:
Any chance you guys could actually investigate and fix this problem?

I believe the problems the original poster, "Redirect Left", had, were caused by a GPUGrid's inability to properly start tasks after a power interruption.

I believe that other problems that are unrelated to a power interruption, should probably be in their own thread, maybe.


If I read the first post then I do not read anything about a power interruption.


You'll have to read more than the first post, I'm afraid.

You are right Jacob, my bad.

Okay, got several over 80%. One completed at 100%. Could really be the power spikes on the line and the UPS not reacting to them the way it should. I'll see and report.

I know for a fact that before having the UPS, if the lights went out and you were using Boinc with GUGRID you would lose all the work units. After the computer did a reboot, the screen would flicker, get a video driver recover message and all work units would error out. That started MONTHS ago and I also reported that. Nothing has been done to fix that or maybe it just can't be fixed. "Leave applications in memory" does not help to resolve this.

Thanks

Some UPS do not handle the high-efficiency (e.g., 90+ Gold or Platinum) power supplies well. That is because of the Power Factor Correction (PFC) that these supplies use. Most UPS output a stepped-sinewave, which is only an approximation to a true sinewave. That can cause problems with these power supplies, and as a result you have to de-rate the maximum power of the power supplies by about 2/3. So if it rated at 450 watts, you should not try to get more than about 300 watts from it, or you run into trouble.

FWIW, I now use the CyberPower "Pure sine wave" UPS, which avoids the problem.

Okay. I have the Xfinity 1400VA. It uses modified sine wave. Got a Corsair AX1200i and a 750W power supply on it. That's one of the problems.

Thanks
