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?

You mean v12.1?

Yes, my mistake. :P

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.

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

That's great! :D Is that on a 6870? Also, what settings?

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.

Awesome. Thanks for the link!

Linux pushes the best numbers. Use the settings mentioned in the link.

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)

Yes thats exacly 6870 :) from sapphire
here are my settings:

V 1,200
Mem 300MHz
~cgminer 2.2.1
hreads: 2

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

what you exacly mean Utility rating ?

Post by: jake262144 on February 02, 2012, 08:14:07 PM
Code:
U:8.22/m
Utility is the number of solved non-stale shares per minute.
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.

with intensity 14 i am getting about 5
with less is around 4-4,5 :)

I already told you to measure it over at least 24 hours.

thats the result for around 7 days :)

Luck plays too big a role in utility to make such a claim I'm afraid.

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.

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)?
 ???

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.
