I remember reading somewhere on these forums that if you drill a small hole on the face of the fan about half a centimeter offset from the center and insert oil in there (wd-40 will work, but not as long. What you're suggesting is basically to relubricate the fan motor. You can actually pull the fan hub (basically it's a giant magnet) from the stationary part. Just insert 2 or 3 screwdrivers and pry. That's what I did. In my case I think I had some coils burnt out (no idea why....), which is why the grease didn't help. Yeah.... no. I tried this for THREE fans, and I obliterated all of them (The plastic part behind the fan would always break, rendering it impossible to remount the fan ever again) |

I have that exact card with a seized up fan too! I tried some lithium grease but it didnt help, so I did this: <picture> I remember reading somewhere on these forums that if you drill a small hole on the face of the fan about half a centimeter offset from the center and insert oil in there (wd-40 will work, but not as long. I have 3-in-1 oil and works great, wont evaporate), it'll release the friction and the fan will spin like brand new. I did it for this card and it worked great. Before it would spin maybe only 60rpm. Now it spins nice n fast, and even wooshes at higher RPM. http://www.ebay.com/itm/221020808125 |

On the page I linked in the OP, there are measurements of the (ridiculously expensive) replacement fan. That is identical to the one on the card. The one you linked, while a bit smaller (75mm instead of 85mm), would probably fit on the card. If I don't find anything better, I'll probably buy it. For $4 including shipping there is not much risk. Two options, replace the whole cooler with a aftermarket one, ArticCooling, Akasa, Thermalright etc, or cut one more blade of the fan, so the balance is even on the even. I will try the second option first, because it is already broken and you loose nothing for a try.
Unfortunately, since I broke off the first blade, I broke off many others. I didn't even think I could "fix" it by breaking off another blade. Thanks for the quick responses. If you do choose to go the "chinese fan" route, be wary that shipping could take as long as a month, or more. Also quality -can- be sketchy. I lied when I said it "plugs in perfect". Whoever assembled the fan attached the 2 pin plug on it BACKWARDS (ground would get fed 12v and 12v would get fed ground). I eventually figured this out before burning out the fan and re-attached it the correct way. Also make sure the power plug you need is correct. The fan I got was only a 2 pin. It didnt provide sensor or have a wire for PWM, but neither did the card. |

OCZ still makes ram? I thought they stopped that years ago?
free bump

$83/card, pretty good deal. too bad i dont have any money :<
|

why would you want almost double the amount of money on amazon gift cards? 210 btc is only $1075

those are double molex. I want single molex |

shares are subject to the exact same luck as finding blocks. you just have bad luck finding shares.
make sure ur stales are low too.
also phatk is old. find phatk2, its much faster.
your memory speed is really weird. you want around 300 for worksize 256 and around 150 for worksize 128, but it doesnt appear that you are using a worksize either. no wonder your mhash is so low.

I've got a 5830 that'll clock to 1250 MHz and do ~500mhash. Most only go to 1000 and do 315.
My 5850 even with a voltage bump only do about 950 and around 375 mhash. Beyond that they crash after a short time. they don't get hot. It's just instability.
5830 @ 1250MHz? Bullshit. Same same alleged card doing 500 MHash as well? Also bullshit. By my calculations, it would do just shy of 410 at that speed. To answer the OP, if you decide to use windows, use driver 11.12 or 12.1 (no cpu bug with either single or multi gpu), and 2.1 SDK for fastest performance. Lots of people seem to rpefer using cgminer, but if you want max speed, I suggest using phoenix w/ phatk2 kernel (about 2% faster than cgminer) |

I wasn't aware you could flash a 5870 bios onto a 5850 without seriously damaging it.  |

Do you have any single molex to single PCI-E power adapters?

This probably won't help, but here's what I know.
For one of my rigs running LinuxCoin, which has three 5970s (6 GPUs total), the OpenCL devices (GPUs) are identified as follows:
[cl:0:0]
[cl:0:1]
[cl:0:2]
[cl:0:3]
[cl:0:4]
[cl:0:5]
I do not know what the first number after "cl" means or how it could be anything other than 0. See, I told you this might not help. I always thought the first digit after the "cl" refered to the platform of GPU you have. Like you'd see different numbers in there if your rig had 5XXX series cards mixed in with 6XXX series cards. iono for sure though. Nope. AMD APP isn't the only OpenCL computing platform. There is also ATI Stream (also known as SDK 2.1, and yes it IS a seperate platform from AMD APP which is SDK 2.4 and higher), and Intel opencl, and probably many others. I have 2.1 and 2.6 installed on the same computer. Platform 0 for me is SDK 2.6, and platform 1 is SDK 2.1. I have both installed because 2.1 is faster, but isn't normally detected by some miners unless AMD APP is installed too. |

Free bump for great cards. The cooling is overkill for bitcoin mining (should really be undervolting; heat will be the least of your concerns); more or less gaming cards. Unfortunately, I can't make any offers on these. Most I would offer is 25 coins each, which I imagine would be insulting. Grabbed 3 5870's on ebay for cheap on different dates  |
