Hi Miners,

I want to spend some time to give you an update and share my experience with the three current options. Catalyst 11.6, 11.6b and 11.7. I do skip the 11.8 as I feel this is too early stage to be worth a look.
I am not comparing technical details but will have a look at the mining experience, hashrate, temperature and stability.

I have 3 machines running, all of them with Win7 64bit. I am using one 2x HD5830, one 4x HD5830 and one mixed (HD6970, HD5850 and HD5830) setup.

Let's have a look  Shocked at the different drivers and my experience with it.

Catalyst 11.6:

pros:
  • Lowest GPU temperature
  • Lowest CPU usage
  • Normal overclocking behaviour.

cons:
  • Dummy plug required
  • Flash/Youtube freeze bug (Machine freezes often when using flash hardware acceleration. For potential fix disable hardware acceleration in flash player menu.)

Catalyst 11.6b:

pros:
  • Dummy plug not required*
  • Normal overclocking behaviour.*
  • Contains various bugfixes since 11.6

cons:
  • higher GPU temperature than 11.6
  • slightly higher CPU usage compared to 11.6
  • partly fixed Flash/Youtube freeze bug (Machine freezes sometimes when using flash hardware acceleration. For potential fix disable hardware acceleration in flash player menu.)

Catalyst 11.7:

pros:
  • APP SDK 2.5
  • Flash/Youtube freeze bug fixed
  • Latest (non beta) driver available.
  • contains various bugfixes compared to 11.6
  • Dummy plug required not required*

cons:
  • CPU usage 100% at Single and Dual Core systems (possibly a APP SDK 2.5 bug)
  • High GPU temperature

* If you want to under/overclock your card you still need dummy plugs or a monitor to be connected to the card. Otherwise software based overclocking tools don't work, especially in Multi-GPU configurations.


Hashrates:

307 MHash/sec - HD5830@950/300
390 MHash/sec - HD5850@950/300
425 MHash/sec - HD6970@940/840

Temperatures:
(4x HD5830 Rig - hottest card as reference)
Temperatures are snapshots of the status at this moment. They do vary with room temperature and workload..

11.6   ~79 degree Celsius (automatic fan was at 76%)
11.6b ~81 degree Celsius (~84%)
11.7   ~84 degree Celsius (~92%)

Conclusion:
If you use a dedicated miner machine you probably don't need the latest bugfixes and you pay more attention on stability, temperature and CPU usage. From this perspective I would recommend to use Catalyst 11.6.
If you mine with your standard PC which you also use for gaming then probably Catalyst 11.7 is the better choice.
The hash-rate did not noticeable change between all the drivers.

Feel free to comment..
Happy mining  Grin

End.

nice rundown.  I hadn't considered the temperature being different between versions.

Another pro for 11.6 v. 11.7 is MSI Afterburner works right with no limit overclock/underclock on 11.6 but not with 11.7.  (possibly other OC software as well?)

Big time, I'm on my way I'm making it, big time, oh yes

Thanks for your nice way of asking  Tongue
What do you want with screen-shots? What to see?

11.6 is the best. With SDK 2.1, 0% CPU. With SDK 2.4, 30% CPU (1 single 5830).

I'm not about to hear my fans running at 100%, that's loud as hell, it's all about 11.6 since I don't want 100% core usage

No, its not too hard. What is apparently hard is for you to answer his question: What would you like screenshots of and why?

I'm not one for donations but if you must go ahead and I will keep you in mind. =)

Small update..

Did some testing with 11.7 in combination with APP SDK 2.4 (from 11.6 driver). Works really well, even better than 11.6 standalone.

You need to be bitch slapped in real life. How rude.

Endeavour79 thank you for the awesome write up. It's certainly helped me steer clear of updating from 11.6.

Find something I said tip worthy? 1Nf47w5mk7a425xLTrV8U4eswqveoxwTv1

I like my software up-to-date so I'm running Version 2011.0524.2259.39378 on my Windows XP.
No under/overclocking done on my ASUS Reaeon HD 4890 and it never crashes, maybe because I run m0mchil's miner at --frames 90?

Other info: 850 MHz (default clock)
2590 RPM (automatic control)
13v, doing ~71'C

Gives me around 91.918 MH/s [Rej: 37/1095 (3%)]

I could easly push it to 103 MH/s, but this makes it just too tricky.

Nice writeup, not sure if what you're saying is true in all cases though. People seem to have varying experiences for some of these findings.

For instance, I was able to remotely boot and overclock/underclock a windows machine with 11.7 preview, and had 1% CPU usage over 3 cards. No dummy plugs or monitors were plugged in. But I couldn't successfully add a 4th card so I rolled back to 11.6.

I'm using ... I want to say it was the 11.8 preview ... on a crossfire'd 5770 machine with no dummy plugs or monitors hooked up, with TightVNC, and I can overclock and underclock them both using BarelyClocked

I use TightVNC on all my mining machines (Win7x64) and the ones with single GPU's don't need any special attention (monitor hooked up or dummy plug), the ones with dual gpu's need to have a monitor hooked up to each and moved to each card to start mining on that card, then I can switch to the other card and begin mining, then remove the monitor completely. I don't want to use dummy plugs because there's a 3-5 MH/s difference per card when the monitor is attached and when it's unhooked.

All rates with Phoenix 1.50 / PhatK
------------------------------------------------------------------------------------------------------------------------------
5850 - 400 MH/s  |  5850 - 355 MH/s | 5830 - 310 MH/s  |  GTX570 - 115 MH/s | 5770 - 210 MH/s | 5770 - 200 MH/s

11.7 is great! It fixed the problem with UVD and other GPU accelerated apps freezing the system when mining.
