Newbie GPU miner questions

[SkyNet]

hi everyone nice to be here
its great to find out that bitcoin has such an active community

I am a newbie GPU miner with a few questions and I would like your help
I started mining with my existing 5850 card with a bit poor results I think. I am getting around 305mhash with the cpu overclocked by the amd overdrive to 775mhz and ram clocked to 900mhz. I am under windows and using Diablominer along with the latest graphics drivers.
I don't know though if these results are good or poor. It takes a while though to produce one BTC I can tell you. I registered in the bitcoin.cz pool and using this. Also I registered in mtgox and I am pushing the btcs' there (don't know if this is a good idea or if I should use the process described here).

Do you consider that my current setup is producing the correct mhash?

Also I am planning to buy soon a 5870 card. can these cards work simultaneously in the same rig? Do I need to connect them somehow?

According to these charts you're ballpark for the card.

Wow how do they clock the cards more than 775Mhz?

[Grover]

My bad wrong digi-coin charts.

Still going to be about the same times 1000. LTC mines in kh/s due to the scrypt algo.

Per your question, likely factors, make of card, type of cooling, and who knows how long they ran the card at the stated clocks.

For 5850 card, around 300-340 MH/s is good.

If you get 5870, you are going to get something about 370-400 MH/s.

Also, I would not recommend you to crossfire two different cards. Buy another 5850 and put it crossfire with your existing (or buy two 5870).

I'm pretty sure for mining you don't use crossfire at all.  There's no frame to split in two and render separately on each card, so you lose performance.  You want each card doing its own work to get max performance from each card.

No Crossfire here enabled
5850 maxes out around 300 and something (775Mhz GPU and 300Mhz RAM)
5870 maxes out around 400 (895 GPU and 300Mhz RAM)

I also have a poor 5570 laying around maybe I will just plug it in :-)

Why not.

No need xfire for mining really

[chong900208]

Overclock your core clock to 850-900 and set the intensity to 9 should give you more hashes

[SkyNet]

Intensity is at 9 already
I cannot clock the 5850 more (not allowed...)
Is there a way to do it?
5870 crashes above 895Mhz, this is the top (even 895 is borderline...)

[s.paulson23]

Overclock has limit, not to damage gpu!

Limit can be removed sometime, http://forums.guru3d.com/showthread.php?t=338906

careful if using guide!

donate btc here if good guide

thanks mate
Afterburner does not work for me though for some peculiar reason....

thanks for the info guys!

mine 5850 mines only with 270 seems to i have to configure it right.

well since i got my avalon i dont need gpu mining anyway

Hi guys, im a newbie to GPU mining too and i recently downloaded the GUI miner software and read the faqs after the post, one of the faqs was to do with the GUI miner crashing, KIV wrote that if this problem happens to anyone then post up the bug report so someone can take a look, only problem is i cant post on that thread as im a newbie, my bug report is shown below, if there is any helpful feedback id love to know.

Post a link to the thread you wish this posted in, and I'll post the above data in the thread for you.

Great Link for the digi-coin charts !!

I have tried both crossfired and not crossfired [I have 2x r6770's ] using them separately with two different workers (same username) seems to work the best along with giving u the ability to track each cards output.

This also allows you stop mining on a single card for use, gaming, movies, etc...
