It took me a little while to get mine right again, i had to bump my vcore a little however i will try and lower it again. But i think something changed with the memory modes? I had mine on memory mode 1 when i started to muck about with the OC and it worked so i left it. But now i have it on mode 2 (OC mode) and its all fine while mode 1 is no good.. 24hrs prime stable at 1.255 so will try 1.25 and then lower it.. i just want to make sure that its stable =) don't want to give bf3 a chance to crash :P

Hi Scotteee

I'm currently running a Corsair AX1200. Notice you have the Enermax Platimax 1500w PSU. Is it worth the upgrade?

Hey yestime,

What system are you running? if it's quad 680's and a heavy OC then i think it is, the AX1200 only has 6 pci-e connectors, then you have to run molex for everything else, the enermax has 10 pci=e connectors, it's expensive but is powerful with all the plugs you need

In saying that the corsair AX1200 ran my quad sli for 2 weeks without to many dramas, although i think it was to blame for some instability issues

Well this is my first attempt at a WC system. Initially just wanted to WC the CPU and motherboard. Kinda got carried away when I read about dual loop system. Also didn't realised the 3 x pumps I used draws quite a bit of power. Didn't help the fact that 2 x 580 & 470 are known for being power hungry. Bought most of the part beside the water cooling gear before 680 came out. Looks like I either wait for the true 680 (probably named 780) to come out or change to the Enermax 1500Watt. As the AX1200 isn't stable enough for me with everything I got hooked up.

Makes my custom loop seem like a childs version of yours. :O

Do you have pics !

scottee, now that the 690s are out, thinking of dual-quad?

Thinking about it? My money's on him camping out in front of NetPlus or Austin!

Hey Iron

Yer i'm really keen on the 690's, i was going to retire to them as my gaming cards for the next year or so and lay off the whole upgrading n chasing number thing for a while,
but what's even cooler now, is these 690's OC just as hard as the 680's, so this means in quad sli they may actually out perfrom the 4 x 680's in quad sli,
because with 4 x 680's your max OC was about +120 on all 4 but on the 690 they are seeing +170 so interesting times ahead, i may get a double wammy, the cards i want and the 28k on 3dmark11

Already got my pre orders in everywere come on, sif i wouldnt sort that already

If only we had a 4x 480/580 setup to measure just to see how far we have come!

I can tell you! My 4way GTX580s @ 1000/2200, i7 3930K @ 5Ghz draws 2.2Kw across 2x 1500W PSU. 1350W on PSU1 and 850W on PSU2 in 3dmk11.

Im waiting for Ivy-e and GTX780s for my next upgrade, should get away with a single PSU then!

Jesus.

A 4 x GTX680 + 3930k rig with overclocks will draw around the 1kw mark under 100% load.

The GTX580s must be super power hungry to make your system draw 2.2k

Yeah they are over volted to 1.35v and draw mega current!
Estimated at 380W per GPU.

I was pretty amazed i was able to run quad 680's overclocked, with overclocked 3930k and everything else maxed on a Corsair 1200! they really are one of the first NV cards in a while that made me think wow

Hi All,

I had been asking over in WP about a quad 680 4GB machine. I'm trying to work out what the best MB / CPU combination for such a rig is. The machine will not be used for gaming, rather CUDA number crunching (our own code). We are an engineering consultancy, we realise it will be expensive so are happy to buy good gear, but don't want to throw money away.

As background we benchmarked our code on a variety of cards (670, 680, 690 and Tesla) and found the 680 provides the best bang for buck for us. Hence we are looking to build a rig around these. Does anyone have any guidance on the best MB / CPU combination for this, do I need dual 2011 socket chips to provide 16 lanes to multiple cards? Single chips seem to have 40 lanes, so i need multiple?

I was thinking of an EVGA Classified SR-X 270-SE-W888-KR for the motherboard. However, this can only run 3 at 16 x PCIe. And the only MB I've seen which supports 4 x 16 only has a single CPU socket so wouldn't be able to run 4 x 16? Is quad SLI at 16 x a dream, should we tri SLI instead.

Any help much appreciated.

AsRock Extreme11 X79 Mobo is what you're looking for mate. It's able to run 4x 16x because it has 2x plx chips.

Thanks Dev One.

However, I'm a bit confused with things, when I look at the specs on the Intel website for the LGA2011 Xeon chips for that MB http://ark.intel.com/products/64593/...l+xeon+e5+2630 it lists # pci lanes as 40. Does this mean a single chip will be unable to support 4 x 16 (64 lanes)?
