Title: What drivers do you use? Post by: humanage on February 01, 2012, 08:55:30 PM What drivers do you use for mining? I tried getting the latest(AMD v2.1) out of curiosity, and my hashrate dropped from 651MH/s to 550MH/s on my 6870s. What do you use for best results?

I didn't experience any loss from the upgrade, maybe try restarting your PC? Also make sure your settings in GUIminer (or whichever program you use) haven't changed. Title: Re: What drivers do you use? Post by: Arnold2222 on February 02, 2012, 12:02:40 AM as i reded best are 11.6a also SDK 2.4 or 2.5
personaly i am getting bests results on cminer 2.2.1 and 11.6a around 335mhs now after update of cgminer, was 314 before greetings Title: Re: What drivers do you use?

Also, what settings? Title: Re: What drivers do you use? Post by: blissfulyoshi on February 02, 2012, 03:51:08 AM CGMINER usually does need much setup. Just add -I 9 to the end of basic pool information, and that is usually enough to get the highest hashrate (assuming you already overclocked your card)
As for myself, my 6870 is at 290MH/s with only a slight factory overclock (bascially no overclocking at all) on CGMINER. Title: Re: What drivers do you use?

Linux pushes the best numbers. Use the settings mentioned in the link. Title: Re: What drivers do you use?

Try Diablo Miner you should squeeze 300 or so out of that card Title: Re: What drivers do you use? Post by: blissfulyoshi on February 02, 2012, 05:47:19 AM CGMINER usually does need much setup.

Try Diablo Miner you should squeeze 300 or so out of that card I am only getting 280 with Diablo with the settings on the first post. Are there any better settings I should try? (When I did overclock test long time ago on phoenix 1.4, I easily passed 320 (maybe 330 but it has been a while), but the energy spike is not worth it imo) Title: Re: What drivers do you use?

Also, what settings? Yes thats exacly 6870 :) from sapphire here are my settings: ~drivers 11.6a (in system info you ll see as 11.7) --for out of pc-- ~GPU @1000 MHz V 1,200 Mem 300MHz ~cgminer 2.2.1 hreads: 2 intensity: 14 ~result up to 335Mhs --while use pc-- ~GPU @1000 V 1,200 Mem 600MHz ~cgminer 2.2.1 threads: 2 intensity: d (dynamic) or 6 ~result up to 314Mhs atm testing p2pool Title: Re: What drivers do you use? Post by: jake262144 on February 02, 2012, 06:00:59 PM Good gods below, never use intensity >9 with 5xxx or 6xxx cards!
You're lowering your Utility rating processing incredibly long batches of calculations and throwing them out when they've become stale. Intensity is a fine-tuning parameter, higher does not imply better. Decrease intensity to 8 or 9 (either will be fine) && RTFM Title: Re: What drivers do you use?

Title: Re: What drivers do you use? Post by: jake262144 on February 02, 2012, 08:14:07 PM Code: U:8.22/m It's a slightly better indicator than MHash/s, although at the cost of higher variation. Run cgminer for a day or so to even out the variation. Title: Re: What drivers do you use? Post by: Arnold2222 on February 02, 2012, 08:34:05 PM with intensity 14 i am getting about 5
with less is around 4-4,5 :) Title: Re: What drivers do you use? Post by: jake262144 on February 02, 2012, 09:58:23 PM I already told you to measure it over at least 24 hours.
Title: Re: What drivers do you use? Post by: Arnold2222 on February 02, 2012, 10:02:07 PM thats the result for around 7 days :)
Title: Re: What drivers do you use? Post by: -ck on February 02, 2012, 10:31:24 PM Luck plays too big a role in utility to make such a claim I'm afraid.
Title: Re: What drivers do you use? Post by: -ck on February 02, 2012, 10:35:19 PM I expect that intensity 7-9 is optimal for just about every available card. Increasing intensity beyond this will likely make the displayed hashrate fluctuate more wildlly, but the average hashrate will be the same, and utility is unlikely to be affected positively or negatively. However, depending on which SDK/driver combination you use, CPU usage may rise quite dramatically when you get beyond the optimal value.
Title: Re: What drivers do you use? Post by: humanage on February 03, 2012, 02:43:50 AM OP here. After messing up my AMD drivers, The closest I can get to my 655MH/s is 620M/s.
I'm using drivers 11.10 and SDK 2.4, with clocks at 1020core and 370 memory. I've tried playing around with clocks, but barely a difference, same with GUIMiner Pheonix flags(-k phatk VECTORS BFI_INT FASTLOOP=false AGGRESSION=10) Should I just re-install my windows 7(even tried service pack 1)? ??? Title: Re: What drivers do you use? Post by: ChanceCoats123 on February 03, 2012, 03:31:45 AM Running 11.12+2.5 over here with my 5870 @ 950/300. In cgminer 2.2.1, I get ~ 385mhash/sec and in poclbm I get ~405mhash/sec at the same settings.
Now I'm just not sure if poclbm will actually submit valid shares for me. I mine with P2Pool so I was using cgminer since it is the recommended miner. However I can't argue with 20 extra mhash/sec. Both of my shares so far were rejected though. I'm not quite sure what's up. |
