Hi all.
I have a ATI Radeon 4800 Series (I think its a 4850 but everywhere I look on my machine it just says 4800 Series. I bought this computer from a friend so don't know for sure what it is.)
Just looking for a noobish step by step guide to get some mining going. I hear of people getting 4BTC a day that would be great but I have no idea even where to start.
Edit: Ok I found a thread with a link to an article on here to get me started. Will come back if I have any questions.

I've been in Slush's Pool since I started with my 4 Mhash/sec...he doesn't seem to mind me basically mooching and getting my bit nickel every 39 hours or so. :p Just worked out overclocking last night with a program called RivaTuner (I really am that big of a noob -- I accidentally put the memory clock speed on my nVidia 9300 up to 750...I was restarting in safe mode before I knew it...) and the new card will be here tomorrow, along with a buddy of mine to help me install it and the new PSU. I've been reading as much as I can on the forums...but the vast majority of you guys are way further along than I am with regards to the whole tech thing...especially hardware. It's never too late to learn, though.
4 BTC a day sounds like a fine return on my investment for my time. I'm probably going to hold on to them and see what happens. I got a great deal on this card, and the PSU will support just about any modern card out there (including the coveted 5970 if I get to that point), so I can definitely upgrade if this goes well. I'm even thinking about starting my own Bitcoin business...but that is another thread for another forum category.
I'll be back tomorrow night with news.
Edit: I think you did help, and I will definitely share the wealth.

Welcome to the wonderful world of bitcoin mining slurch!
Say what new card are you getting? I'm presuming it's an ATI card of some sorts. ...ooops..nevermind I found out ..I guess reading a bit further up the thread is a good idea eh? heheh

Hi there...new the the forums and just picked up a 5830 and a 600w PSU to go along with it -- they arrive Monday, and I'm excited to really get started. I am not as tech savvy as a lot of you guys so I'll be getting a friend to come and help me install these pieces (surprisingly, the power supply is what I'll need help with -- I'm awful with cords)...I did manage to already set up CPU and GPU miners on my own, though, so I'll probably be fine once I get the hardware out of the way. I'm using an nVidia 9300GE, which is CUDA in name only. Between the Athlon Dual Core 4850e (not OC) running at ~2.5GHz each and that terrible card, I've been pulling down about 3.5 mhash/s...which is pitiful. I make laughable amounts of BTC right now. I figure I can turn the CPU miner completely off once I get this card installed (no point in running it, really). Also thinking about slaving the gf's parent's computer, once I see what hardware it's running. 
Maybe I'll see a whole bitcoin one of these days...
Anyway, looking forward to being an active part of your community. I'll come and let you all know how everything turns out once I get the card installed.

Welcome to the community
, you should be able to get around 275 mhash/s on that card. I recommend keeping a steady fan speed rather than one than speeds up as the temps rise. With mine I kept it at around 50% or 2000rpm. You'll want you temps stay around 70c. To temps low and gain some speed try lowering the memory clock to 300mhz. It worked with mine 5830 (but not my 5870). With that card at the current difficulty you will get around 4 bitcoin a day. I suggest either Deepbit ( http://deepbit.net )or Slushs Pool ( http://mining.bitcoin.cz )If you can sell you card down the line for what you paid for it and put that money and some bitcoin you earned towards a better card (5870 or 5970) it will be worth it.
For me the key is getting the system stable, getting it running and leaving it alone for as long as I can while I do other work. Than when you go check on it you will surprised with the amount you earned. Much funner than sitting there watching them come in a few at a time.
Hope i helped, if I did please donate!
Edit: ALSO, Catalyst 10.7 and Stream SDK 2.1 worked best for me.

Got it all set up! 5830 is running at 975/300 at 70C, and it's pulling 260Mhash/sec. I was having some stability issues at higher clocks, so I just put it down a bit and left it. (It crashes almost instantly at 1000/300, 990/300 I had a few shutdowns after only a few minutes of use, etc.).
I also popped my old 8800gt in another slot and OC'd it, so it's adding another 30MHash/sec.
Going to add another 5770 a buddy has lying around tomorrow and get another 160-200MHash/sec too hopefully. Overall, much quicker now for not much of a $ investment.

I'm glad to see you're getting decent results from your 5830, I just picked one up for $110 after rebate (seemed to make more sense than the $145 6850, $165 5850, or $200+ 5870, etc). I cancelled an order I had for a $145 after rebate 6850. I had to pick up a new power supply too (to get 2xPCIE, I got 4xPCIE on this guy to make sure I never have that type of problem again), but I never really trusted my old one anyway, kinda sketchy. I guess I'll sacrifice the gaming upgrade I would have got with the 6850 to get a better miner and a nice futureproof PSU.
(6850 was $30 cheaper than the 5830+PSU)
Should be a nice upgrade from my 8800GT that's pulling 24Mhash/sec at the moment! I'll post my results here when I'm all set up.

You will get a ten fold increase in mining speed at least.
I saw on Ebay Asus 5830s which have no voltage lock for between $120 and $140 and I think that it may be able to squeeze out something different, these cards don't get very hot, i keep it in the 60's at 50%fanspeed, stable @ 280 mhash clocked @ 1000mhz/300 , i feel if i could control the voltage i can squeeze much more out of this card
prices change all the time, especially that the these newer cards are out you should see a drop in 5 and 6 series cards...
im very for buying used video cards , i got my 4850 for $50 and i will make my money back making the 5830 $100, ill get some more money sell the 5830 for $100 or more, and keep doing it over and over until i get a $1,739,548,822.45 graphics card. its going to be hhhuuuggee
try use that tool i posted a few posts above, i dont think your 5830 will be stable at 1000mhzprices change all the time, especially that the these newer cards are out you should see a drop in 5 and 6 series cards...

if the program does not crash does not guarantee that your calculation is correct.
That program is good for gaming testing not opencl. I am steady at 1000/300 as we speak. Have been for atleast 24 hours.

The best bang for the buck mining is the HD 5870.
A few places around here sell it for about $185-$200 CAD new, and it will have 43% better performance per clock than a HD 5830 because it has 43% more shader units (1600 vs 1120 on the 5830).

Well, at stock clocks the 5870 has a 51.7% theoretical advantage over the 5830, but at the price frankiebits saw it for ($120) versus $185, the 5870 has a 54.2% higher price. OK, so the 5830 wins in price to mining performance by only a tiny amount at those prices.
At only 900mhz it puts out about 330,000 khash/s, I've also seen 390,000 khash/s at 1030mhz (although with my reference cooler, I can only keep it at about 930mhz unless I want a hairdryer in my room). This is all using SDK 2.3 on Windows with the 11.2 driver. I tried SDK 2.1 as well as older drivers and found no significant difference at all (less than ~5m increase/decrease). I also didn't notice anything significant upgrading to SDK 2.4.
I wouldn't agree that the 6870 is a better miner than the 5850 either. The 58xx and 68xx/69xx series all top out at roughly the same core frequencies, most will cap out anywhere from 950-1000mhz for mining. HD 6870 is already 900mhz and doesn't have much headroom, HD 5850 is 775mhz and has much more headroom for overclocking. That all being said, HD 5850 already performs better for mining when both are at stock frequency.
My HD 5850 at ~920mhz sees roughly 300,000 khash/s. Comparing my HD 6850 at the same frequency of 920mhz.. it only sees about 215,000 khash/s.

The relevant comparison should not be a 5850 at 920MHz. Also, in my post, a 5850 was not compared to a 6850. Those two cards aren't the same wattage. While the 5850 will most definately overclock better than a 6870, both cards at stock clocks will produce mining results that are similar. However, the 6870 will perform better in games. That's how I have it worded in my previous post. Also, in my post I point out that even a moderate overclock on a 5870 will pull it ahead of the 6870. From the way I've ordered the sentences, it can be inferred that the 6870 at any level of overclock can't compete with the 5870 at even a moderate overclock. I'm just restating that to clarify.
I will agree, though, that a 5870 will give you the best performance for the given clock speed.
EDIT: Looking back, I did not emphasize the fact that the 5850 and 6870 have similar mining performance. Oops.

DP FP: Double precision floating point
This won't affect mining at all. Hash calculations are done with integer operations and some compare operations. That said, a 6870 can compete with a 5870 in mining, but only if you overclock the crap out of the 6870. Even moderate overclocks on a 5870 can pull it ahead. As far as mining performance per unit price, the 5830 does look like the best option. Mining performance per watt is still going to be the 5970 with the 5850 and 6870 really close behind.
Also, AMD's primary impetus behind creating the 68xx cards was to reduce wattage but keep performance nearly the high as the 58xx cards. Basically, consider Barts the Cypress redesign. A 5850 and a 6870 have roughly the same TDP rating, yet the 6870 performs better in games than the 5850.

Thanks, it kills me I can't control the voltage though. I could push so much more out of this card if I could. I am going to stick with it for a month or two , hopefully be able to sell it for almost what I paid for it and get either the Asus 5830 or something else, but from what I see the best bang for the buck mining wise is still a 5830 , i see the Asus ones going for around $120 on ebay and I bet you can squeeze alteast 320 mhash/s out of it.
On here http://en.wikipedia.org/wiki/Ati_comparison you can see why the 58xx series kicks ass for mining, 2154 million transistors compared to the 68xx series 1700. I assume for gaming they are better
but certainly not for mining.This also caught my eye and made me get a 5830 even though I am not sure what it means
but only a few cards have it, does anyone know what "Double-precision FP" is and if it effects mining speeds?

Hmm I can't get it stable. Well I can get it stable when only mining , but it I am mining for a while and come to use the computer it freezes up.
This never happened with my previous card, but then again I can't control the voltage on this card, something I didn't know until I received it....
Anyone know if it is possible to control the voltages on the Sapphire 5830, I only have 2 options...
Well otherwise I found the 10.7-10.10 drivers with stream sdk 2.1 to be the fastest.
I tried to see if the freezing up was due to the software versions but it happened on all of them.....
What to do , what to do....
Edit: Sticking with 10.7 and SDK 2.1 , got it stable (where i can still use PC @ decent speed without freezing) at 990/300 at 275 mhash/s...
Wish I would have known I couldn't change the voltage, the card to go with if your getting a 5830 is the newer Asus version...

Clocks: 1025/300
HashSpeed: 285 mhash/s
These setting beat out (driver/stream) 11.2/2.3 and and 11.4/2.4
For now I am going to stick with these settings , they seem stable , temps are good.
If anyone wants to try and see if they can something better with drivers 10.8-10.9 it might be worth a shot.
Hope they help, if they do throw me a coin or two

im using cat 11.4 beta with steam sdk 2.4
clock 870/1250
getting 325000 khash/s

Hmm just lost 10 mhash/s using these newer versions. Man this is frustrating.
So far the best results I have got at my current clocks (1000/300) is 275 mhash/s with SDK2.1 and 10.7 Drivers...
What version of card do you have?
For 5000 series card sdk below 2.3 only works good.
The best seems 10.12 or 10.11 with 2.1 as said before.
The 11.4 & 2.4 preview akka BETA works well with 6000 series.

Lowering memory below 300 Mhz actually decreases hash/s & freezes windows.
Also, it seems there is some kind of formula there between memory frequency & core frequency, it seems in the form of core clk =3(3.
??) x mem clk which gives the Maximum hash/sI get Maximum 280 Mhash/s at 1038 core clk & 360-370 mem clk.
Seems it differ for everyone. Please try increasing mem clk every 5-10 mhz while mining in back & see the change in hash/s & Please also post it, if u can able to get any max hash/s at any particular frequency while keep the core clk at max with out freezing.
lowering mem clk reduces TEMP up to 10C to me.
you can increase the core clk up to <1040 with out freezing. even 1041 freezes after some time.
i got freezing at 1047 after 1-2 hours mining & not touching pc
Thanks I will play around and report back.
