@Evo Keep the stagger at or below of 40% of total RAM. It appears to double buffer, so will use twice the configured value. Also note that if plotting multiple drives, the values are per drive. So if you have your plotter set to use 4GB, and are mining 4 drives, you better have 48TB.
Thanks for information. I've just upgraded to the latest version of the gpu plotter (4.1.3). Prior to this I'd been using 4.0.3 and it RAM usage seemed to be correct. With that version I aimed for 50%-60% of total RAM. I'll definitely keep a close eye on how much RAM is used when I try the latest version...my poor old HP only has 10GB at the moment.
@Dillion lol what i mean is we never lost power lol. even when the big earthquake hit last march 11 2011 the electricity and internet is up(lucky? maybe). we dont know in the future but up to now havent experience having a brownout.
