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.


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 ).

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).

+1 and there isn't a big performance penalty...

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

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.

I'm a noob just starting, all donations are welcome.  13DXKRXQncUnWAFtemSwNH7boRZfEfsg5a

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

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.

just noting.
 seems like a waste 3 xt's should be doing over 1500mh/s maybe a riser cable to get them away from each other

those are in 3 different PC's 2 are using 375watt PSU which work just fine. 1 has a 600watt and an XFX 7870 in with it too one that is running 1200Mhz 525mh/s. So I know it isnt the PSU's.
All my rigs are using 375watt supplies no issues

I am using 13.1 drivers I tried 13.2 but they cards mine like 10% slower so I am not going to install anything newer than 13.1... does 12.8 even have drivers for a 7870?

how are you getting 505mh/s out of it only clocked to 1100? all the ones I have Sapphires dont hit 500 till 1150mh/s

I can't seem to connect to the pool no matter what I do.

Add new workers, delete others, reinstall the program.

May be time to switch pools...

It is most likely your miner program that can't connect to the pool.

Start by checking that it is correctly configured (for stratum - not getwork!) and/or try running the proxy - if the proxy connects then you could set your miner(s) to point to the proxy and run that way.

Hah... you can thank me for 240790  Grin

I'm surprised I found a block at only ~825MH and in about 4 min too.  Ain't luck a fickle mistress.

port 3333
stratum.bitcoin.cz

make sure you can get out to these 3 IP's
Name:    stratum.bitcoin.cz
Addresses:  54.215.3.101
          54.225.117.74
          95.211.52.40

You can do a traceroute of the IP's but keep in mind you are only checking if you can get out to that IP not completely there, this is to check if your own firewall is blocking yourself
