AMD "Never Settle" 12.11 Driver - benchmarks

[Final8y]

Yes, however ive now found a work around for AMD 7xxx reference users until the hotfix driver is released.

You can actually set the proper idle clocks in CCC, click apply and suddenly it remembers the idle voltage/clocks. Its not ideal but its better than before. There might even be a way to save it as a profile in CCC, which you can trigger by pressing a hotkey or something. Trying to figure that out now.

Does anyone know how to create and save a profile in ccc that remembers overdrive settings?

 

[Final8y]

Ok enough of my grinning.

While in the overdrive tab and after you have hit Apply, open presets, Add Preset and give it a name and hotkey if you like and you can Invoke it from the system tray menu.

 

[Final8y]

You beauty.

However the hotkey is not working, nor is when i select it from the system tray, only when i open up CCC and click the actual preset?

Hmm, very strange.

Could be a bug in the beta, try doing it all again.

Nevermind i got it working, just had to setup a hotkey. Yes, for the love of god yes it works perfectly.

I guess i should spread the word and distribute the fix to the masses, but part of me thinks sod them spent hours already on this lets get gaming! Its every man for himself in this world!

Funny as i just rewrote what i was going to say as i originally wrote that the hotkey could be down to user error.

Yes the same situation with me yesterday that i wrote to you in the other forum and i said you can do the rest as im feeling lazy now

 

[Final8y]

I'm about to spread the word, check my other thread, did i miss anything out before i pass it on to joe public?

Make sure that they understand that they must be on the Overrdrive screen when they make the preset.

I don't use afterburner to clock at all, in short is rubbish for ATI cards, I use Trixx and use afterburner to monitor the card via the G19 app.

I found Trixx very easy to use but AB seems not to be much of an issue on the 5xxx cards as i have not had to disable ULPS or mess around with missing dll files.

AMD 12.11 Beta Drivers 8

http://www2.ati.com/drivers/beta/AMD_Catalyst_12.11_Beta8.exe

And new CAP.

Updated list

•Improves CrossFire scaling for Planetside 2
•Improves performance up to 5% in Max Payne 3
•Includes single GPU performance updates for Far Cry 3
•Resolves the Skyrim lighting issue (missing a lighting pass) for the AMD Radeon HD 7900 Series [secondary problem from b7 fix]
•Resolves the hang encountered playing Dishonored on the AMD Radeon HD 6000 and AMD Radeon HD 5000 Series
•AMD Catalyst 12.11 CAP1 (should be used in conjunction with AMD Catalyst 12.11 Beta8)
•Max Payne 3 (DX9): Resolves light reflection corruption in single GPU mode
•Far Cry 3: Improves CrossFire performance
•Hitman Absolution: Improves Anti-Aliasing performance for single GPU configurations
•Sniper Elite 2 – Resolves the flickering encountered when pressing Alt + Enter in CrossFire configurations
•Crysis 3: Improves CrossFire performance and fixes corruption
•Devil May Cry 5: Improves CrossFire performance
•WarFrame: Improves CrossFire performance
•Carrier Command: Gaea Mission: Resolves single GPU corruption when enabling Anti-Aliasing through the Catalyst Control Center
•AMD Catalyst 12.11 Beta 8 for Linux includes significant performance improvements for Left for Dead 2

I cannot comment on anything compute-related, as I don't actively follow those driver threads internally.
As for the issues people are encountering with the CAP, we found a bug that causes the 12.11CAP1 installer to fail on some systems. We're just going to bake those fixes into a new beta driver and get it posted for people (beta9). You'll be able to install it right over the top. Stay tuned.

There will be a fixed CAP, but it will come after the new beta.

Crossfire is much more versatile than SLI. The highest performing card will match the lowest performing card, so to get the most out of it you should match the type of card but it is not necessary.

That's not true but the slower card can sometimes hold back the faster under certain circumstances.

In practical terms there is load balancing. I believe that is correct, the more powerful card will be under utilised hence matching the speed of the slowest card.

I have ran my cards out of Sync, i have ran one as low as 500Mhz while the others were at 950Mhz.
Running them all at 500Mhz was slower.

ATI/AMD has been doing asynchronous clocking with improved performance over identically clocked cards for almost five years (maybe longer, I forget). Literally anyone with a Crossfire setup can run one card overclocked and one at stock and will see a performance improvement over running both cards at stock.

I know when I got the additional 5770, I used Kombuster to make sure everything was stable, and with the 6770 overclocked from 850/1200 to 910/1300 and the 5770 running at stock clocks it basically ended up with the 6770 at roughly 90% load and the 5770 at full load.

I overclocked both to the same clock speed and it was 100% load on each. The 6770 isnt a great clocker so I havent even tried to see how far the 5770 will go. I may try it now if it actually makes a little extra difference.

I would look at the fps and not the load, i have used profiles on my Quadfire that have givem me 80 % load across all the GPUs and have given me 30fps i have then used a different profile that has only used 25% loading across all the GPUs and given me a solid 60fps in the same game.
This is game dependent on how its all utilized and being on quad GPU gives CF more leeway on unbalanced clocks.

There are some games that don't even trigger max clocks or much loading on the other GPUs until there is enough going on and mostly because i Vsync.

I am familiar with the clocks being different, it is the load balancing. I suspect if i paired an old 3870 with my 7850 i would cripple the performance and it would be lower overall. Thanks for sharing the info about the different clocks being better than equal clocks, that looks promising as it shows load balancing is not equally distributed. I still think it would be possible to reduce performance by matching two cards that are vastly different.

I would say its better to have equal clocks, performance can be affects by the slower card, its just not absolute, sometimes the OC on one is worth it and sometimes its not.

Running one of my GPUs at 500hmz on purpose did reduce performance, but running all of them at 500Mhz was even worse, so its not a case equal is better as in speed but a case of one being higher potentially will gave more performance than all being the lower.
I would say forced unequal clocks could add more micro stuttering.
