I tried again with increased intensity and the reject rate has jumped.
With my usual -I setting i get over 9% rejects. But this way i get over 1770 WU and higher hasrate.
With reduced intensity i get a little over 1400 WU and lower hashret but between 2% and 3% rejects.
Which is better ? The WUs are the actual work units, so the higher number - the better and rejects are considered, correct ?
Whats cards are you running ?
couple of r9 290x on that one
OMG, I can't get more them 1400-1450 WU on my 290x, do you mind sharing your config ?
I run 4 R9 290's and they run solid at 3.28 MH/s with a 6% reject rate (does jump here and there). My settings are Thread - 32650. - Intensity - 20. Worker size - 512 (I have tried 1024 with no real increase, but higher reject rate). 1 GPU thread and 1 Vector. I use GUIMiner with scrypt. I do NOT have the cards overclocked. Everytime I try to move the memory/core clock even +5 I get lower hash rates. Stupid 1st release cards.
I have had good success on 1 of the cards running Thread at 24550 and the rest of the settings stock with +7 powertune in MSI Afterburner. This takes the card from 830kh/s to 875kh/s stable. But only 1 of my 4 cards will accept this without crashing. I have to figure out the issue there, but that is also the only 290 in its own rig. Other 3 are on 1 motherboard with 2 PSU's so that may be the issue. Or the OS load may be the issue.
