Title: xfx 7950 LTC mining with many stales, need help please. Post by: biged214 on April 08, 2013, 03:31:59 AM Hello all,
First off thanks for having this forum and for all the wonderful support. I have a XFX7950 that I'm running and I keep coming across people who keep saying that can easily get passed 500Kh/s with these cards while mining LTC. I can't seem to do this without having the pool and also cgminer tell me that I have lots of stales. If I keep my current settings, which are: cgminer --scrypt --shaders 1000 --intensity 12 --worksize 256 -g 1 Temp: 80.0 C Fan Speed: 76% (3370 RPM) Engine Clock: 1150 MHz Memory Clock: 1450 Mhz Vddc: 1.250 V Activity: 97% Powertune: -10% Fan autotune is disabled (0-85) GPU engine clock autotune is disabled (900-900) I get this below (5s):298.5K (avg):305.8Kh/s | Q:13 A:48 R:0 HW:0 E:315% U:7.7/m ST: 2 SS: 0 DW: 24 NB: 7 LW: 46 GF: 0 RF: 0 WU: 223.5 GPU 0: 80.0C 3389RPM | 298.5K/305.8Kh/s | A:48 R:0 HW:0 U: 7.89/m I:12 It seems like anything I adjust I either use more power or my stales go up and my Kh/s on my pool goes down from what my miner says I'm doing, I understand that the pools calculate Kh/s by accepted shares so that is really my concern. Is there anything I can change to increase my Kh/s output while having my stales stay down? Thanks in advance for any help :D Title: Re: xfx 7950 LTC mining with many stales, need help please.

i had my xfx ghost dd 7970 at 650mhs but the temp was like 90+ degress getting alot rejects after almost a week of tweaking, now doing 655mhs but at 70 degress at the expense of 4 6cm fans blowing directly on the card and getting 1 rejects every 1000 mind you this is bitcoin Title: Re: xfx 7950 LTC mining with many stales, need help please.

Post by: elchorizo on April 09, 2013, 04:02:39 AM Another thing to try is reaper as opposed to cgminer. Reaper seems to work better for me and with less rejects/work resets.
