unless you have a 6 series ati card.

which begs the question:

is the ati 6770 a rebadged 5770 and therefore compatible with sdk 2.1?

[d.james]

I'd say no to that.
but you can always try

I can do gaming/mining/video on my Nvidia card, but ATI = instant crash.

Really? My 3 year old plays Assassin's Creed: Brotherhood, Just Cause 2, and Bulletstorm all the time while the AMD card is hashing!

I've run three cards through his computer too, a 5850, a 4870, and now tonight a 5770, and all three worked fine while hashing!

The key is to set the right aggression so as not to interfere with his games; with the 5850 it was 4, with the 4870 it was 3, and I haven't found the exact one for the 5770 yet but I'm using 3


This is of course all with Phoenix.exe -k phatk

For standalone video problems, try turning off hardware video acceleration. In MPC I just use Overlay Mixer as the renderer, it seems to work well. Of course, then your CPU has to do all the rendering, so make sure you have a powerful CPU because the trend is to offload that work onto the GPU, which you are now actively disabling.

I just downloaded the 2.1 SDK and I observed absolutely no change in hash rates.  However, my temps went from 71C down to 67C with nothing else changed but the SDK.  This totally confuses me, but I'm not going to complain

It was true before phoenix+phatk optimized for 2.4, I'm getting the same speeds with it and less hassle while installing (only need to install the 11.5 package).

Did you actually uninstall the 2.4 SDK and change the device number in your miner?  You'll see the device numbers change for the video cards between 2.1 & 2.4.

No, the crash only happens with the 6000 serie, it's a OpenCL bug, you start something that use the GPU while mining and ta dah: freeze. Even opening GPU-Z while mining lead to a freeze. But, if you first open GPU-Z, let it load and then you restart mining, everything is fine. This of course does not apply for gaming and what else 

The old CAL doesn't have this bug, if someone make a mining client in CAL that problem would disappear

Yes to the Uninstall, and by "device number" do you mean Platform ID?  I had to specify PLATFORM=0 in my Phoenix Miner batch file after I installed 2.1.

[Meatball]

Not sure what the syntax is for devices with your miner.  With Guiminer/Poclbm with SDK 2.1 my CPU is Device 0 and GPU is Device 1, with SDK 2.4 it's GPU first, CPU second.

Whatever your syntax is, just make sure your miners are pointing to the correct devices/cards.  On my 5xxxx series cards with GUIMiner/Poclbm I see almost 10% faster hashing with 2.1 vs. 2.4.

[presha]

does it fix the 100% cpu usage thing? getting tired of setting the affnity for every process 

[dinker]

1% or less cpu use here for my 5850 and intel quadcore.

Does anyone know a way to manually uninstall the APP runtime? I can't install a different version of it, because it thinks it's there when installing it, but doesn't show up to uninstall it.

[d.james]

you can get an app called driver cleaner from guru3d i think.
it wipes any ATI or nvidia drivers clean, assuming you want to reinstall them anyways.

I think Driver Sweeper from Guru3d was discontinued, but thanks for the idea.  FYI, I did try completely uninstalling ALL the ATI stuff using the uninstall manager, but when I reinstalled, it still wouldn't install the APP SDK runtime.  Everything else installs fine.

[mmortal03]

So, it turns out that the issue was indirectly that the dummy plug I bought off of cablesaurus on ebay doesn't seem to work (or there's something I have to do with it besides plug it into the graphics card!).  Once I plugged an actual monitor into the card, while I still couldn't get the APP SDK Runtime installed, OpenCL was detected, and I could mine.  Can I be sure that the problem is simply a bad dummy plug?

Not true. The phatk kernel is optimized for the 2.4 SDK. I get better results with phatk + 2.4 than with any other combination.

Yeah, it's all relative to your setup/machine.  No matter what I try, phatk with any SDK performs worse for me than straight poclbm with 2.1.

There is no 'magic' setup that will work for everyone.  Everyone needs to experiment with different miners, miner flags, drivers and SDK's to find out what gives them the best hashrate.

[new_in_this]

6990 still crashes whenever any hint of video is detected when mining.

Same on 6970, had to reset computer.
(5850, no problems)

No other "visible" changes.
