I had temp problems with my 4800 series cards (overheating) until I switched them, the 4890 was in the first PCIE slot and the fan was completely blocked off by my sound card, and the 4870 was not blocked at all, I switched them so now the 4870 (reference) is partially blocked by the sound card and I removed the Killer 2100 NIC so the 4890 isn't blocked at all (I had yet to removed the NIC in the pic), the 4890 STILL runs hot, the shadercore is arounf 96° while the core is in the low 80°s, my 6850 can't come soon enough...lol

is this the first documented casualty of the bitcoin wars...? the first of may I'd guess...
Nah, just coincidence. I've had my CPU and both GPUs running DC apps of one form or another 24x7 for years. With Bitcoin I stopped my CPU efforts, so the system is actually under less load now.
But wow, my HD4350 and 9800GT sure are putting up some crappy numbers...
can't believe I missed out on the 5830s
I setup a notification alert last week but they didn't email me
Same here. I checked on a whim tho and was lucky enough to find them in stock.
Wow that sucks. So a $325 12000 BTU window ac is only going to cool a handful of 5830x4 miners.
I may need to come up with a new plan. I guess if i don't oc the cards they should be stable even if its 100f out. I was hoping a window AC would let me keep max ocs.

I will buy your 5870 and frankenstein that shit...lol
how many 5830s did you order?
maybe. keep in mind you don't have to keep a perfect ambient temp. The ambient can get up to 80 or so and the GPUs will still be reasonably warm.

when you open Bitcoin.exe it's here...
that's where your wallet address is located, obviously though, that is my address...
8 5830s
2 mobos
2 cpus
2 psus.
on top of my 5970 and 5870
A window ac unit will be fine for now but I'm planning to invest 1/2 of monthly proceeds back into mining gear (if things keep going well) so I was hoping it would scale a bit higher.

You know, this may just give those out of warranty "dead" video cards a second lease on life. Any card with damage (broken DVI/HDMI/VGA ports for example even with blown caps perhaps) should be OK, as long as the GPU can still hash. I remember a while back there was a case of a cooler that damaged the DVI outputs of 5970s or maybe 6970s. Those cards can now be used without any issue to hash away.
Well, consider where all that heat goes before you despair...It doesn't have to go straight into your room. May not be pretty, but you could duct the card exhaust (and cpu cuz it's hot too) out the window next to your AC. Hit up your local hardware store for some dryer exhaust tubing and whatever end-pieces strike your fancy. An in-line fan wouldn't be a bad idea either, just to keep the air moving.

do you guys go by what your BTC pool website is telling you your mhash/s is, or do you go by what your miner app tells you?
my account on bitcoinpool.com is telling me i'm hitting 1100~ mhash/s, but each of my miner windows are reporting around 340-350 mhash/s....

The app gives you real time data. Pools give rolling averages.

got my tracking for my provantage 5830 today. In the meantime I've got my poor nvida gpu's cranking.
Oh and I think the first confirmed "casualty" of bitcoin would be the guy who had a heatstroke and suffered minor brain damage due to his farm.
btw, i've had my 2 nvidia cards crankin since yesterday and have earned a whopping 0.08 of a bitcoin. They're not kidding when they say nvidia, don't bother.

Yeah, but because he was dumb.
This is true, There was a follow up that I'll try to find again where he explained the whole deal. It basically came down to a 4 pc farm with 5850's crammed into his bedroom and he was to lasy to put the window AC unit it.

Apparently there is a whole site dedicated to "accidents" for bitcoins.. wow.

it's ridiculous how inaccurate their 'average' is though... now it's saying i'm pulling 1.3 ghash/s.... running two stock 5870s :|
According to the calculators linked earlier, I should get just under 1 BTC/day at 550 MH/s. I'm now at 1.15 for running 550 MH/s for ~36 hours and 270 MH/s for another 24 hours, instead of the ~2 BTC I should be at. I am mining with BTC Guild because I have seen it mentioned here often. Is this just variance that should go away with time or should I see if something is set up incorrectly? Thanks.
BTC Guild is having server overload issues so to deal with that sign up at http://mining.bitcoin.cz. Make a duplicate miner in GUIMiner for each GPU using the new pool login but put -f32 instead of the -f12 on your main miner. The -f flag is some type of priority, lower is more important. Whenever there is no work on the main BTC Guild miner the slush's pool miner will take the unused Mhash and put them to work. This way either can go down and you still get bitcoin one way or another.
Go to "other" when you select the pool in GUIMiner and use api.bitcoin.cz on port 8332 instead of using the "slush's pool" option. Apparently this gives "optimal performance" according to slush.
EDIT: Also check your miners to see if they aren't running at full load. Mine were getting work for a few seconds that stopping over and over using BTC Guild.

Thanks! Managed to get in on 1 just before they ran out. Maybe the last one?
Hmm, not to be mean, but what about hearing damage? Those thing might be hot, but I know they can also get LOUD also when sandwiched together!
There is a difference in not accurate and useless. I think a 50% difference is pretty useless. However, one of my 5830s does not appear to be 100% stressed, so I may have found the problem. Any ideas on why it is at 60 - 70%? I have tried lowering the "-f" flag down to 20 and below with no difference as well as changing the clocks to something more stable. I am also running F@H on the CPU, but I don't think this should matter.

Check your CPU affinity per process, check & separate which processes is on which CPU Core, and put one per core. That helped me out on my i7.
My plan is to move the mining rigs to my garage and build a small room around one of my windows. Then install the window AC.
My poor house AC already runs too much without having to compete with bitcoin.

WHAT? Speak up!
no seriously, Yet another good reason to keep your farm in another room of the house.
As a F@H person, My farm lives in the basement and can be as loud as it likes.
Like this? http://hardforum.com/showthread.php?t=1609314&highlight=garage
I'd just put a fan in the window or put your rigs outside (protected from rain). The profitability of mining will be much more dependent on electricity cost in a few weeks and there is no reason to waste that power chilling the air for your hardware. If it's in your garage get a powerful box fan that blows out the window and/or some 3k rpm 120mm server fans tied to the GPU's to bring the temps down.
we had a few days in the 90s last week tho. Wouldn't an ambient temp like that cause problems for oced hardware even with great airflow? If you guys think 6 or so 240cfm deltas would do just as well I'm all for that idea.

Edit: nm, was reading through last page.
Do you have a basement?
Tried the affinity lock and it seems to have helped, at least for the time being. Went for 90% to 99%. Thanks.
no, I live on a slab QQ.

yeah, if that "story" is even real, how long have people been folding...? yet I haven't read one instance of it happening now with mining...?
notice I said "confirmed"...lol

Pools also take into account stale/invalid shares I believe when figuring the Mh/s.
