How many GHash/sec are you getting with those 2x5970?

Are you generating less than 13.07BTC/day?

Each GPU is around 285Mh/s so 1.14Gh/s total. Stock clocks, poclbm. I'm going to upgrade to Phoenix miner.

Get the latest poclbm miner (2011-04-26) and pass -v -w 128 -f 60 (the -f 60 you might want to tinker with, but on Windows, I had some stability issues after a week or so and it only changed the hash rate by about 3MH/s max, but my machine is used for work as well via VPN). I get roughly 366MH/s running Windows 7 x64 (latest Catalyst drivers and Stream 2.4 (which is probably not required) using a stock MSI Radeon HD 6970 card with no overclocking and have a fan profile setup to keep the temp at 75-78C. I have seen some postings elsewhere of using -w 256, but I am not sure that is helpful or not [going from 64 to 128 certainly was].

I would love to hear how this works out on Ubuntu (or even Gentoo). I suspect you will get the very best performance on a Windows 7 or Vista machine with Aero turned off using the parameters I mention above, mainly because the drivers for Windows are undoubtedly where they spend most of their efforts on improvement.

thanks for your answer!

so i will get myself a 5970. is there any manufacturer you would prefer (with regard to my board)?

How would I (using linux) disable hardware acceleration of the flash player?

I don't have a preferred manufacturer, I also don't have a 5970, but a 5970 is basically 2 of my cards on one board. My cards were bought used from E-bay and they're running like champs. I would recommend getting a card that has the fan at the end instead of the middle so it's pushing air toward the back (out) of the case instead of the middle where half of it is going back into the case.

On the official Adobe Flash Player you right click and turn off hardware acceleration. It would depend on which program you are using in Linux as to how/if you can turn it off if you're not using the official version.

Hi there,

I consider buying a 5970 and plug it into my present hardware. That is an ASUS P5N-E SLI, Miditower and 550W Power Supply.
Do you think that is possible?

I'm afraid there might be two problems: 1. Incompatible PCI-E Slot, 2. Too little power supply.

As an alternative, what would be the most efficient upgrade?

Another question: With my present hardware, videos aren't played fluently as soon as I launch poclbm-mod. Because I use that machine for everything, it would be important, that I can mine AND work at the same time. Is that possible? If not, I might reconsider the investment.

I appreciate any advice!

1) As long as it's a PCI-E x4 or better (which yours is then you're good). I'm mining on an Intel LGA 775 from the same era no problem.
2) 5970 uses almost 300 watts, 250 almost certainly enough for the rest of the system. You should definitely upgrade it if you're not going to use it as a dedicated miner.

Flash player, Firefox 4, Chrome, IE-9 and quite a few other apps are adding direct video support for rendering with opencl, the same interface you're using for mining. Using any program that accesses opencl is going to impact your mining speed. Flash player can be told not to use hardware rendering and will pass the load to your CPU. Some apps can't be told not to use it.

If I had the money this http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274 would be my dream board.

Because of the spacing of the slots, it looks like you would only be able to plug in 4 cards and not 5. But still, that's better than most boards.

Is it correct that you can only have up to 8 cores in linux ? Meaning you can connect a maximum of 4x 5970s for ex. ?

Yep. This guy http://blog.zorinaq.com/?e=42 accomplished it with some serious hardware hacking.

x16 or x4 or x1 does not matter as long as you've managed to plug in your card and it is recognised by bios.

Welcome to bitcoin community, schone, lots of people here are very helpful.

I do not know anybody who actually tried that. But theoretically MHash/sec should be the same. If you have 4GB version it probably would be a good idea to sell it and buy 2x 2GB cards. Twice the bang for the same buck.

I wish they produced 512Kb version of 5970.

P.S. the suitcase coming with some 4GB cards does not increase Mhps either Grin

Could you tell me if it matters if the PCI-E is x16 or x4? Does it slow down communications at all?

I'd like to thank you all for replying so quickly to me today! I never got a chance to say thank you.

This is a total noob question but how does one find out how many cores for the 5970?

Also, does it matter if its a 2GB or a 4GB 5970?

How does one join a pool?

There are 2 GPU's (Cores) on the 5970 and 6990. All 5800 and 6800 series have 1 GPU each.

There are quite a few pools, each has their own benefits and drawbacks. The biggest difference between all of them is speed. They vary right now between 200 Mh/s and 15 Mh/s. The bigger the pool, the smaller payment you get, but they are more frequent ... smaller pools don't solve as many blocks but have higher rewards. Once your system is set up you download a client and connect it to a user account set up on a pool website.

The pools are (sorted by current speed high to low) at http://mining.bitcoin.cz, deepbit.net, bitcoinpool.com and btcmine.com.

It does. 2 GB version eats less electricity and much cheaper.

Does it also produce less MHash/sec? or the same at around 600?

The 5970 is roughly equivalent to my 2x 5850's and I am getting that on average right now as part of a pool.

Alone (w/o a pool), one wouldn't get the same?

There's no guarantee when you mine alone. Pools help keep the income more toward average.

You might want to look at this site. http://www.alloscomp.com/bitcoin/calculator.php

Right now the 5970 is rated at ~600 Mh/s. I'm sure it can get better with phoenix client.

Edit: Looks like phoenix is getting 347 per core or just under 700 Mh/s.

At 600 Mh/s it would take 7.75 days on average to get 50 BTC on average. But it could take up to 3 weeks.
Even at 700 Mhz it could take 6.5 days on average or 19.5 days if it runs long.

There is a good deal on the TX950 at newegg. Not modular but good reviews!

Any idea how much you're looking to spend?

2 x 5870's put up better numbers than than 1 x 5970 but use more power since there's 2 cards. 5970's are more than twice as expensive as 5970's, even on ebay. So for those you are looking at a power vs price trade off.

6990's are newer and roughly the same price range as 5970's. Drivers work on Windows and there's mixed success on Linux. There's probably room for performance gains in future drivers.

You have to decide how much you're looking to spend, which cards and how many, find out what power supply will support those, a motherboard with enough slots to support the cards (up to 4 cards, but it's not cheap), etc.

If the box isn't going to do anything other than mining, you can get away with the lowest power and speed CPU for the board you pick, and 1-2G of memory since the CPU and memory aren't used in the mining process, only running the system hosting the cards.

My Ubuntu installation is less than 4G, so you can use a decent size/speed hard drive or small SSD.

Looking to spend about 1000USD for the 1x5970 installation, but would like to have hardware capable of supporting an extra 5970 and adding that later.

Can I reasonably expect the results shown on http://bitcoinx.com/profit/? about 6.5BTC/day with 1x5970?

6.5 BTC sounds about right at the moment. Remember, however, that difficulty changes every two weeks approximately. It almost always increases (it's gone down twice, once fairly recently). As difficulty increases the daily amount of BTC will decrease.

Curious for the PSU suggestions for a dual 5970. Seems you could get by with a good 850 watt like an HX850?

850W is recommended, but good 750W one will work too (not recommended). Don't use cheap nameless PSUs, they are usually overrated.
