I run 7870xt at 1100mhz (1.113v) and 750 mem for bitcoins ~505mh/s Happy medium undervolted and overclocked!
Scrypt runs poorly on these units 850mhz .981v stock mem ~410kh/s@ 20 I 16834 thread.

Is there any tricks to cut down the Video Driver from crashing. Besides lower GPU Mhz.
I am asking because I have 3 machines identical in all ways brand new win7 installs 64bit, Sapphire 7870xt cards.
I can run 2 no issues at 1200Mhz GPU mining 525 mh/s while the 3rd one the video driver seems to crash above 1145Mhz after several hours.
The 2 at 1200 run at 71C and 76C while the driver crashing one runs at 75C.

What psu are you using - you need a good 750-850W for that kind of set up.

Another noob question if yall don't mind. I've been looking around in cgminer and when I go to "Pool Management" and "Information" I noticed that it says "Discarded work due to new blocks". Mine seems to be a really high number compared to my actual shares being accepted. Mines around 14%. Is that something to worry about or does it really make a difference? If it is something to worry about, how would I go about fixing it?
Thanks.
Thanks.

But 3Th are exactly 2 minirigs and if it was them, its even good news, as we will know that they work fine with startum, while for those few hours it is clearly just testing and not 'testing'
EDIT: The best way to test stratum is not the test network, but at the inventor's pool, so good news actualy

minirigs are now 500 GH/s not 1500 GH/s
Like they changed from 30 to 25 GH/s and 60 GH/s to 50 GH/s

I am running 3 7870xt in a system, 13.5 beta drivers, temps from top to bottom are 83 @975 clock 750 memory 100% fan speed, 82 @900 clock 750 memory 100% fan, 75 @1050 clock 750 memory. stable for 3 days now. I get 1.25 G/h total

Did you look around for the version 12.8 drivers? Those seem to be the best to mine with.
Not sure about that. For me when a card gets sick all of cgminer crashes resulting in zero mining, but on 13.1 mining continues and the card stays sick (or dead). June 10, 2013, 04:44:37 PM

Did you look around for the version 12.8 drivers? Those seem to be the best to mine with. In any case, go to device manager, uninstall the driver, make sure when you click Uninstall, you check "Delete driver software for this device". Once uninstalled, try reinstalling (Preferably version 12.8 ).

Are all the cards running at default voltage? Perhaps the third one needs a little more?

You can underclock the memory.
Add more cooling.
Other than that there isn't much. Unfortunately that is simply the nature of video cards. No two (of even the same model #) are exactly alike.

Possible. But jumps are always in 1,2,3,4...TH. So minirig is 1.5TH and doesn't look right. You could do it but unlikely. I think it is 100 blades... No overclocking...

Wohoo, total pool hashrate is going down last two days and I just plugged in another HD 5670…looking forward to you, rewards 
I don't think that that big jump of 3th was "normal". I think it was ASIC miner. They jump from time to time to pools. I'm not sure why. Maybe they have problems with there pool. But not 100% sure since they do find blocks in that time. Might be that they have just performance issues and they need to decrease load on there pool.I thought the Rumor was butterfly labs was "testing" equipment before sending it out.
never mind it takes "several" 5gh/s to make a pool increase by 1,000gh/s

To be honest, I'm not real sure how to figure out how many mH/s I do get other than using what's on the "Main Account" page on Slush's site. It says:
Average hashrate in last 10 rounds: 1716 Mhash/s
I've been mining non stop for about a week now with my rewards ranging from .00265261 to .00329058 which was the 4 minute one about 30 minutes ago.
So this is normal?
Thanks for the help
I made a mistake and thought you are asking for a different pool. It is normal... and reword looks right for your speed. You will have long and short blocks... On short blocks you will also see bigger variances since luck plays bigger part. You can be lucky or unlucky for short time but in a long term it evens out...Average hashrate in last 10 rounds: 1716 Mhash/s
