want to do quad-fire and eyefinity 24... help/seggestions

post #1 of 4
Thread Starter 
First to put suspicion to rest no I'm not trolling.

Intel is due to release Ivy Bridge for LGA 2011 soon, and I recently purchased 20 identical 17" monitors topped with in my next build I was planning on going with 4x SAPPHIRE Vapor-X Radeon HD 7970 GHz 6GB with my next build.

I'm aware of downfalls of multi-monitor setups, power consumption, money and all of that but I have a few questions that hopefully some of you might be able to assist on.

1. Does the video card support 24x monitors I now this is not specified as an eyefinity6 card but you can buy display-port adapters... The only time I've seen this done was with 4x 5870 and that some manufacturers couldn't support 24 monitors is this something I should verify with SAPPHIRE?

2. all 20 of my monitors are the old non wide screen LCD's and only have vga out, I know that there are "active" vga adapters for dvi and display port to support eyefinity but before I go hunting down four more monitors would it be way less of a pain to just get different monitors and if so should I try to get some with display port or would dvi be fine?

Thanks for any help because it is supper hard to find information on doing eyefinity with 24 monitors.

1. You are limited to 6 displays per GPU.

2. If you want more than 6 displays simultaneously, you cannot enable CrossFire. Display output is disabled on secondary GPUs because they are slaved to the master GPU for rendering purposes. Frankly, I'm not certain if > 6 displays across multiple GPUs has been officially tested by our Q&A team for compatibility and reliability.

3. The first two monitors on each GPU can be passive VGA to whatever, but the rest must be active to DP.

4. If you want to SLS the monitors, you can only create multiple independent groups of six.

5. Windows is very cranky about large numbers of displays.

All i can say to this is i wish you the best of luck. Seriously when i tried my 3 monitors in 5760x1080 using 2 6950's xfired i had so many bugs, microstuttering that i sold it and am now rocking my 7970. Never looked back, but the more monitors and GPU's you add to a system the more problems you may/can have also scaling will not be as prosperous depends on the game/app and how well scripted it is. I would think xfiring 2 7990's would be a better option, also note that you are limited to the Vram of the first card, and does not combine with 2 card's so 3GB+3GB will be 3GB not 6.

What are you planning on doing with this system?

Thanks thracks the info you provided has been pretty helpful in pointing me in the correct direction. Also after reading 3 I revisited where I got the idea from and realized at about 0:52 it said all cards were active not crossfire, which makes sense.



to answer powerdemon292 I plan on attempting to play some games coding and monitoring.
currently I run 3 gtx580 and run 3500x1920 res (bezel correction) and I like it and don't have to many issues.

I will keep updates as I get them.
