What drivers do you use?

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.

This might also interest you.

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

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

[blissfulyoshi]

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:
~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

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 ?

[jake262144]

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.

[Arnold2222]

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

[jake262144]

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

[Arnold2222]

thats the result for around 7 days

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