Haha lol, honestly this card hasn't been abused in my hands.

Thanks for the bump. Bitcoins are good for me too if one wins and wish to pay by BTC, I will accept happily. We can use britcoinGBP exchange rate on bitcoinwatch.com?

Cheers!

Never overclocked and not been used for mining.

Just in case some one here have interests.

Thanks.

Thanks! I'll run the rig flat and will also install additional (case) fans. Is it better to pull hot air out of the GPUs or blow cooler air towards them?

That speed box fan looks sick. Are you using those fans with your set up? Cheers.

Above is the link to my rig with 3 x 5850s @ 1000 MH/s

Below is for my gaming rig turned mining rig with 2 x 6870 @ 600 MH/s

The 5850s need some additional fans to cool them down. One of them running above 90'C which is a bit worrying. 

I have these cards http://www.overclockers.co.uk/showproduct.php?prodid=GX-259-SP

Will underclocking the memory improve the temp?

The gpus on adapter 1 & 2 saw their temp become lower a bit but not the one on adapter 0. It must be the top one on the motherboard. I'll try running the rig flat to see if it improves.


The thermal paste ain't too thick in my opinion. I just noticed that when I just SSH and check the temps they were all below 75'C but after a while, the temp rises. Does it have to do anything with SSH?

Hello all,

I have a rig with 3 x 5850s installed. When they're mining, the temperature peak 92-93'C on one of the cards. One of them peak at 82'C and the other one 72'C.

Clock settings & temps

Adapter 0= 775Mhz core, 900Mhz memory | 92'C
Adapter 1= 900Mhz core, 900Mhz memory | 72'C
Adapter 2= 875Mhz core, 900Mhz memory | 82'C

I reapplied thermal paste on the GPUs with Arctic Silver 5 4 days ago but the temps don't seem they've improve much. I am worried that the temp is rising over 90'C. I noticed that some ppl underclock memory down to about 300Mhz.

If I do that, would it improve the gpu temp much?

I can't underclock at the moment yet because I am running catalyst 11.5 and it won't let me set it under 900Mhz. I've heard 11.6 would allow me to underclock but I'd like to hear your opinion first.

The rig is running upright atm 90mm fan has been fitted to blow cool air towards the GPUs from the side.

Specs
Sempron 140 CPU
2Gb RAM
3 x Sapphire 5850s
850W PSU
Asus Crosshair IV Mobo
Ubuntu 11.04

I have looked around the board but couldn't find a specific answer, so if you have any suggestion or advice it would be greatly appreciated. Or if you can share a link with a possible solution, that would be great too.

Thanks in advance!

You need to define the server(mining pool) after ./poclbm.py

If you haven't already, register and create a worker on a pool of ur choice. Deepbit, Slush, and BTCguild to name a few.

your command line should be something like this,
./poclbm.py server=http://SecularCalvin@youremailaddress.com:yourpoolpassword@pit.deepbit.net:8332 -d 1

I had the same problem too

Play around with -v -f -w flags and pick the combo which works best for you.

I used deepbit as example. You have to change it to your pool's URL.

Good luck!

Suicide is painless.. It brings on many changes..

Thanks!!

I think it'd be better for you to mine at bigger pool.

You can run bitcoin app as server from one of your machines and then point the other miners to it.
You'll need mining software like GUI miner (http://forum.bitcoin.org/?topic=3878.0), python, pheonix, etc. for each machine.

Haven't tried mining on a mac yet, I dare not try especially on iMacs as they tend to run very hot even on normal use.

Create a worker account at a pool of your choice, you can use that account to run multiple miners.

With the GPUs that you listed, you won't be hashing too much and they will cost quite a bit to run. If you have access to free electricity, then by all means...

3 x 5850s at 1000 MHs/s 65 - 90'C poclbm -v -w 128 <0.3% stale
2 x 6870s at 600 MHs/s 60 - 72'C poclbm -v -w 128 <0.3% stale

With a couple of cooling fans for the 5850s, I could increase the Hash rate to 350-360 each.

Anyone from DeepBit care to help us with 'Mail_Sending_Failed!' error??

Mining at a different pool right now cos i don't want my rewards get transferred to the lost wallet.

No response also when I sent email to the (...)@deepbit.net.

Hope it gets fixed soon.

It should be fine to run all miners with one worker name and pw.

I can do that on my GPU miners in one computer. Haven't tried it on two tho.

Hello all,

I'm from UK and started mining about two weeks ago. Started off with with 2 x 6870s at 600 MH/s. Just built a second rig with 3 x 5850s and getting around 1GH/s from them.

Both are running Ubuntu 11.4 and using poclbm miner.

6870s @ 980 MHz core, 1050 MHz memory, 100% fan speed, 70-75'C
5850s @ 775, 875, 825 MHz core, 900 MHz mem, 100% fan speed, 90',65',82'C

For some reason the 5850s run hotter and I might need to get additional fans.

Less than .3% rejection on Deepbit so I'm quite happy. I'd like to be able to underclock memory on both cards to see if that reduces heat.   AMD 11.6 drivers failed to install though...

Anyway, all the best!

Hey Tycho,
I lost my bicoin wallet that is being used on your pool(due to messd up unreliable bitlocker software on Win7, and not having multiple back up). I tried to change it to a new one but I kept getting the "Mail_sending_failed!" error. Can u advise me what to do please?

Thanks in advance
