Get a good internet connection.
Hash fast enough that rejected shares don't appear.

That might apply for p2pool...for regular pools not that much.
You need to configure the miner properly that's basically it.
Takes a long time to tweak it for your card.

I dont think i have successfully ever gotten the memory on my 7970 to run past 1450mhz frown.gif
will play around with it though and see if i get anywhere...
i was able to get ~600k/hash at stock with 8192tc I:13 g:2 and w:64

I can't really tell by the pic what your settings for memory are. You uploaded it with a small format. But at any rate I still think your can get more performance out of it.

If your at 1800 memory use 1026 core. with 1150mv to start. Make sure your GPU threads is set to 2 thats the key.

But if you didn't under stand my first post here is a better example. Take what every memory clock your doing and multiply it by 0.57. So say : (1700 memory x 0.57 = 969 core) or (1750 memory x 0.57 = 998 core)

For non Reference or 7950 try 0.68 instead.

Now start out with more voltage like 1150mv if that is stable and is doing a high yield then start dropping voltage down slowly until it crashes then bump it back up to last lowest voltage that was stable. My settings I ended up with was

1640 memory, 947 core, 1000mv voltage

I can run two out of three of my cards at the 1700+ memory range. But I decided to leave all of them at 1640m 945,947,947 core.

BTW I'm using beta drivers 13.5 I don't see any difference in performance with 7xxx cards. With 5xxx cards then yes use older SDK.

I've had issues with rejected shares when hashing <50k. The connection to my router disconnects a lot too, and I've gotten 20 rejected shares in a row from that.

Also, why you got a thread going for the multipool but then suggest another way in this OP. I'm confused.



(B) Next you need a proper compute driver for AMD videocard to do the work before you start: AMD Stream SDK it's called. Latest version is 2.7:

http://developer.amd.com/sdks/AMDAPP...s/default.aspx


Your going about everything the best way same way i am doing it wink.gif

It's just driving me crazy. By the way that says "Latest version is 2.7". Shouldn't it say something more like "Latest version to use currently is 2.7."

Also the link doesn't take us to the download page? I'm still trying to find what you're suggesting. Found it: http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/download-archive/

Some cards uses Hynix memory and other cards uses (some other name I can't remember what it is right now). Hynix memories can get quite high clocks. The other ones, not so much.

I used "large" and it has 1050 resolution. Maybe click the pic?

You don't know the full story yet. I've been suggested to do that already and it drops my hash rate from 630-640 down to 550. Now I'm trying to use SDK 2.7 but I'm still seeing the same story.

So now I'm trying to figure out how to find what SDK version I have installed.

Is it normal for Bitcoin Wallet to take so long to sync? It's been syncing weeks for 3-4 hours now and its barley 30% complete, I'd estimate by the green bar.

Takes a day for BTC wallet to sync when you first start.

In Other News Lots of Information added for Digitalcoin in the spoiler under the video!

What is your memory set to in the pic ? I can see everything else.
Are you using 2 GPU threads ?

1800. I haven't set a -g flag yet. should I try 2? Just now tried. Still only getting 556 average K/ps with 1026/1800 clocks.
