Good motherboard for maximum GPU

[kivig]

My system could detect the second card connected via PCI extender but the card wouldn't work because windows reported there is a problem with it so Octane didn't pick it up. This is what I did:

boot windows
go to device manager ( there should be your card but with a yellow warning sign over it )
right click on the card name and disable it
load overclocking software you got with your card
set voltage and TDP to max
enable the card
if the card is still yellow, disable and enable few more times until it starts working
once I do that it works for days until I shut down my computer and do the procedure again

Interesting idea as thin tracks of extender indeed can drop voltage. But still it's dangerous to just rise voltage to max.
Also, as it's mentioned that extender worked fine for some time, perhaps it's thin wires got damaged by current overload, then rising voltage will help for only a short time.

Raising voltage to the max is safe because I'm using overclocking utillity which came with the card.

As far as I've seen overclocking utilities from manufacturer or not state that using them may cause damage and their use is not covered by warranty.
Stock specification is already pushed to practical max with a safety margin. Removing that margin though might not cause immediate effect hardly can be called safe. Especially considering drastic computational load which normal use (games) don't usually demand.

My GPU voltage is set to max and I also force its constant voltage (no failures, better stability). GPU Power is also set to max but Octane uses only about 70% of GPU max power. Both GPUs are watercooled so temps are low, about 40C.

If you pour liquid nitrogen on it, with a bit of hacking or proper utilities you probably can push the limits considerably further
What I meant was about the advice to just push it. Sometimes there is no liquid cooling or even slowed down fan for sake of silence + dust in it and exhaust of which is covered with a bookshelf.
If you use your head, basically nothing is dangerous, or at least the odds are weighted. But leaving it in a form of simple suggestion makes it look like something trivially safe, thus someone may take it for granted even though it might not be the case.

4x 16lanes + 4x 8lanes =) but You need twe E5s =p

purchased!

my new rig is coming:

4xGTX680 4GB
2xXeon 2.2GHZ octa cores
1500 psu Enermax Platinum
32GB
Cosmos II case
ssd Intel raid 1 + raid 0

It will be slower than my quad GTX580 rigs but I'll test the new system with Arion Live to see if the CPUs will fill the gap

It's interesting to understand if Otoy is working to implement CPU computation.

Great choise, Gabriele =)

for arion it will be a beast!
for Octane.. we'll i'd like if they would come
with optimised solution for loading & Voxelsation..

cheers

not so long ago I've tried to look for a possability to house more than four GTX cards in a rig that would have only one CPU. after some time spent online searching for info I've found a mobo that has:

x79 based board for LGA2011 with..
two PLX PLEX 8747 (that effectivelly gives 72 PCIe lanes - & that's enough to run 7cards!)

the biggest problem or let's call it the obsticle is that You actually have is one slot spacing if You want to populate it full.

You can always use risers, but for that means custom case for the rig too..
and for some it's a bit of a problem & is not an option =)..

so is there any solution? well..there has bean a card from EVGA..
watercooled single slot design option of GTX580 (HydroCoper).

these are pricy products..for sure, but considering what You get.. - reasonable priced overall.

&..with modular case, something like CaseLabs STH10 You can get enough space, not only for all this, but for big rads, multi GPU, pumps, multiloop.,etc. - everything out of the shelf, without any need for modding.

here are some pics, with the links, if You get interested..

cheers

Wonderfull rig Gabriele ! My future choice is very similar but im waiting one mon th more.
What about the next NVIDIA TITAN ? Seem to be terrific...

I also want to wait and see how Titan works.
