There seems to be a lot of people wanting 5830s in the Marketplace.  Was there some new development that I missed or something?

One of the best MH/$ ratios, if not the best..

100 bucks for 300MH is pretty damn nice.

5770's are pretty decent too.

I have 1 5830 and 2 5770s.

They can be had used pretty easily for $60-65.  I got lucky and got mine for $40 each.

5770 = ~200 MH/s undervolted @ 890 MHz
5830 = ~300 MH/s

5770: 200 / 65 = 3.07 MH/$
5830: 300 / 95  = 3.15 MH/$

Pretty comparable, however my 5770s are more energy efficient.

My Sapphire 5830s are some of the coolest and most reliable GPUs in my farm. I have 10 of them running on a pair of 890FX-GD70s and those two rigs have run for about a month now without any intervention necessary. Not the best for MH/w but if I could bulk buy another 10 I'd happily do so.

the 5800 series is known for its awesome MH/$ ratios. 5850 is probably the best, but it's been tapped out, so it's just 5870 and 5830. Although 5870 has better MH/W, its MH/$ makes it unfavorable to most users. so that's why 5830 is so popular - best MH/$ ratio, most plentiful (of the 5800 series), and low starting price ($100 vs 6990s that cost $500).

It is pitch black. You are likely to be eaten by a grue.

I'm interested in selling used 5830 cards, working fine.
PM me with an offer (including quantity of cards desired and a $offer per card).

you can find some in the hardware section https://bitcointalk.org/index.php?board=75.0 or ebay. don't buy used though, because there's a chance that the cards are in bad shape, which is what  happened to this user: https://bitcointalk.org/index.php?topic=77099

There seems to be a lot of people wanting 5830s in the Marketplace.  Was there some new development that I missed or something?

I noticed that people buy certain cards for different reasons. The HD6000 and HD7000 series are for higher resell value or gaming on, while HD5000 are purely for mining. And within these 5000 series cards, is can be broken down even further. There is the initial cost factor, and mining costs factor. The 5870 and 5970 are good when it comes to hash rates per kwh, but their initial investment cost is high. The 5830 has the lowest initial cost investment, but it consumes a lot of power for the hash rate output. This is favorable for someone with low cost or free electricity. It seems that the 5850 is the middle of the two 5870 and 5830 in terms of initial investment and electricity cost.

i'll have to disagree with some of these statements

hd6000 and hd7000 may have a higher resell value, but that's only because their value is higher to begin with.  absolute $ is what would matter for our circumstance (maximizing profit from mining bitcoins) and the 5830's have dropped $0 in the last year.  i haven't tracked 5870 values until about 3mo ago, but they've dropped about $25 (completed auctions on ebay).  the 6000's and 7000's have dropped a lot more.  not only in absolute value, but as a %.

expect that to continue, as more recent technology should *almost* always decline in value faster than older stuff.

someone else said they could get 5830's for $60 or something like that, but I don't find that to be the case.  you can get them for around $100 shipped easily.  you can get them for $80-$90 shipped if you spend a little time at it.  the 5850's range from around $115 to $140.  the 5870's from around $150 to $200. 

i reckon 5830's are still the best buy in retaining value, but they also take up a card slot, same as a 5870 does.  so, it'll cost you in terms of space, motherboards, etc.  i converted my 5830's to 5870's just recently, since 5870's dropped into the $160-$170 range.   in a couple months, 5970's will probably be a buy

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

And a lot of them comes with cheap non ref boards with VRMs that cant handle undervolting either :/

I managed to push my 5770 to 0.7v, core 920, memory 200 ...for a solid 198Mhz, they might be the most efficient cards out there, but you's really need to cram 6-8 on the same mobo to get the most out of them.

exactly why I moved on from them.....simply not enough density possible.

Anyone has actually verified and can quantify this affirmation?
I have some doubts that they actually consume the same of a 5870.

BTW: I have read somewhere here yesterday that someone has been able to undervolt a Sapphire 5830. I have one, and a Xfx too, and I was not able to undervolt any, both using Trixx and Afterburner. Maybe mines are locked?

I achieve 1.94 MH/w with my HD 5830s. 10 cards, 3 GH/s, 1550w from the wall. They aren't as efficient as my watercooled HD 5970 rigs which are running 2800 MH/s and pulling 1100w from the wall but they are cheaper per MH. I paid $105 per 5830 and they run right around 300 MH/s for 2.86 MH/$. The 5970s were roughly $425 with waterblocks and they run around 700 MH/s, so roughly 1.65 MH/$. This doesn't include the ~$400 in radiators and pumps that cool my 8 5970s.. The beauty of the 5970 rigs though are that once I got them setup they just chug along and I haven't had to worry about them. The 5830s however.. I have two with fans that will likely fail before the summer is out and I'm sure I'll have a few more fans fail that currently sound fine.

5830s will quickly get you MH/s for cheap. You'll pay through the nose in power but they sure do make nice heaters in the winter.

I have four 5830s running stable at 1000/300 325MH/s. For $100, they are great cards. And can probably sell each one for $50 in the next year or two for the 78xx, or maybe even 88xx series.

I am with you.   It shows there is no perfect GPU they all have advantages and disadvantages.  I don't regret going with 5970s.  Highest MH/W and awesome density.  I couldn't imagine running a 15 GH/s farm using 5830s.  Thats what 50 GPUs?

Still everyone's needs are different.  If someone is a gamer who wants to mine part-time I would say get a 7970 (or two).  Cooler and quieter than 5970 but I wouldn't want to try and build a farm out of them.

I like a mix of 5970s and 5830s. I use the 5830 to load balance the breakers with my 5970 rigs. 1 5970 rig and 1 5830 rig per 20 amp breaker. Puts me right around 16 amps to keep in line with the 80% load rule.
