this thread has just cost me 200 bucks... bought an ati 6870 to run in conjunction with my nvidia 560 se. hopefully my 750 watt psu can handle it. if so, i'll finally be profitably mining!

maybe i'll even be able to save enough for a Lancelot fpga before the Great Reward Halving...

fyi, a 6870 is a nice card.. but a poor miner.  Some people seem to get 380m/h out of it severely overclocked with two gpu threads.  mine won't clock that high, and two threads give me the same as one.. about 280-290.

that $200 would have been better spent on a 5870.  lots on ebay for less than $200.

running about 280 - so, yea, i hear ya. my mistake. i was reading a thread here about best cards to get and hadn't noticed the 6870 was overclocked. i've pushed mine up from 900 to 970 core mhz... oh well, eh? live and learn. still - it's a zillion times better then my nvidia 560 at mining, and is making more then the electricity costs. so, in the end it will aide my march to an FPGA.

3.) Can I run my 5970 mining and game on my 560 Ti (1) is it possible (2) would it be laggy?

No, you can't.

This is because ATI computing goes through video driver. So Xorg must be loaded and running upon the ATI video driver. On the contrary, Nvidia computing doesn't need Xorg.

Wait what? Really? I started mining yesterday in a virtual terminal. I prefer to use a virtual terminal without x loaded because I feel (but am unable to substantiate) that running my miner without x loaded will free up resources on my card to be better spent on calculations. Is it really true that you absolutely must have x loaded to mine with an ati card? Does that really make buying an ati worth it?

I'm sorry. I miswrote it.
This is what I meant:

on Linux, Nvidia video driver and AMD video driver conflict. So you cannot load both. Mining on AMD cards requires the AMD video driver to be loaded: at this point, if you need Xorg (for gaming, for a desktop environment...), you cannot load the Nvidia driver, and you are forced to use the loaded video driver instead, which is the AMD one.

I haven't done it, but I've read that, on the contrary, you can use an Nvidia card for computation without loading its video driver. Nvidia computation doesn't need a video driver: so Nvidia doesn't need to "own" Xorg, if Xorg is there.

I hope I've been a little clearer, now.
Sorry, again.

1.) Can I have both a NVidia card and an ATI card installed with NVidia drivers and ATI drivers running at the same time?
2.) Can I use both cards for mining at the same time? (if 1 is yes, I'd image yes for 2?)
3.) Can I run my 5970 mining and game on my 560 Ti (1) is it possible (2) would it be laggy?


Yes - easy.

I have run nvidia and ATI mixed cards in various two and three card combos for several years.  Mainly under W7, but also XP.

ok, so i've got me my radeon 6870 installed. but clearly i've got an issue somewhere as it doesn't show up in dxdiag or as an available device in guiminer (openCL backend). thoughts?

ignore the above. sorted.

What is a workable solution for the above in Linux ?

Somebody must know !

I think integrated ATI GPU on the mobo or the APU will work in Linux without problems !
 
Too bad Sempron 140 does not have integrated GPU ! Any good mobo with integrated AMD GPU ?

I have 3x5870 mining and GeForce 6600gt to run my winxp desktop so it's not laggy and also I play Quakelive on it while mining 1.2 Gh/s on OCZ 750W PSU. So yes u can run all that at the same time.

Sorry for double post but Internet is lagging.

I can't delete double post so maybe moderator can do it ?

Thank you !

Which can work :

-Intel desktop usage ( crap GPU in CPU or mobo ) + excellent non-affected maximum ATI mining
-Nvidia desktop usage + excellent non-affected maximum ATI mining
-ATI crap integrated mobo GPU / GPU in CPU ( APU ) + excellent non-affected maximum ATI mining

Basically I want to have full ATI performance and no laggy desktop without affecting mining performance at all.

I want independent mining and desktop usage. One does not affect the other. Which Linux drivers is this possible with Huh


Switch to Windows and you can do all these.  Smiley

OK but I am forced to use Linux right now.

Which option do you think will be workable with Linux Huh

Thanks !

1.) Can I have both a NVidia card and an ATI card installed with NVidia drivers and ATI drivers running at the same time?

I answer only for Linux (maybe someone is interested). Yes, if and only if:

a) your first video card (the card in the first slot) is the ATI one;
b) all the monitors you have are attached to the ATI card;
c) you use the Nvidia card only for computing.

Which is completely pointless, if you use the Nvidia card only for mining, because Nvidia cards suck at mining.
If you use it for something else (like some BOINC projects), it should be fine.

2.) Can I use both cards for mining at the same time? (if 1 is yes, I'd image yes for 2?)

See above.

Thanks Lem, this was exactly what I was looking for.
It is exactly the behavior in my machine - nVidia is still working for the sata, usb and other drivers, but the graphics hardware disappears from lspic, which is now quite understandable with your explanation.
It is a pitty and it sucks... oh well! Moving along, nothing to see! Cheesy

Thanks for the input again guys, so Lem do you think it would work best if I just sold the 560 Ti? Maybe I could run GPUGrid or something on it lol

Damn it !!! So this means that you cannot use Nvidia for monitor / games / desktop usage while ATI is mining only ?

What about Intel integrated GPU in the CPU like Sandy Bridge ? What about ATI integrated graphics ( providing you stay in 8 GPU limit ) ?

Or maybe there is no way to have a crap GPU for desktop usage and all the rest powerful ATI cards mining Huh

Thanks for the input guys Smiley Yeah, might upgrade to a ~1200W and throw in another 5970, depends on how my mining goes.

1200W would be complete overkill. 5 GPU's on full load using stock volts might ask for about 700-850 depending on heat and clocks.
