****Official GTX580 user reviews/benchmarking/overclocking thread****

received my card. butter smooth gaming on all games i tried with 4xAA at 2560x1440 :D

problem:
Furmark gets throttled, card usage goes from 100% down to around 30% after a minute or so, and temperature doesn't go up anymore.

so was wondering what stress testing software are you guys using to test card overclock stability?

Use GPU-Z to disable the throttling ;)*

Has anyone here or any tech site actually investigated if this power management effects overclocking outside of burn software yet?
With world record benchmarks for single and quad cards I would assume its not obviously interfering if it is at all...or the owners disabled it?


* I do not seriously suggest doing this, any damage to hardware is your own fault if you do. Can't sue me for it :p

Ran Furmark on mine the other day, stock settings of course, and temps climbed to a max of 82c (GPU @ 100%) and sat there for the duration of the stability test, which I ran for 1 hour. No throttling whatsoever.
 
Well my 3rd EVGA GTX 580 arrived today and it's going to a friend. Won't be keeping it. 3 way SLI with 580's is much too noisy on a rampage III. In sli the fans run at 40% and never get over 60% when gaming. Great cooling over the double slot spacing. In 3-way after about 20 minutes on the desktop the fans were almost hitting 55% just idling. Still not loud, but when I launched Crysis the things got to 80% in no time at all. Not a comfortable gaming experience. Didn't even bother benching to be honest. I guess either watercooling or running something like an MSI Eclipse Plus (1 slot spacing between each card) would be the only way to run 3 way without the racket. Should have listened to the review on Guru3d. At least it goes to a good home and I lose no cash. Oh...another minus and I just realised it, is because I moved my Xonar to the bottom PCI-E 16x slot, the Rampage III automatically downgraded all the lanes to 8x for the gpu's. According to the review over on HardOCP there is not one jot of difference in performance betwen 16x and 8x unless running 5760+ res and even then only on a few games. Still you'd think the motherboard would be smart enough to detect a 1x device in the bottom 16x slot and because nothing is sitting in the 4x slot, assign those lanes to the bottom slot, thereby leaving your GPU's running at 16x8x8x. Not how it works I know. Apparently 16x pci-e slot 1 and 2 share 16 lanes, and 3 and 4 share the other 16 lanes. Back to SLI for me :(

On my asus rampage 3 extreme pci-e 1 and 3 are 16x pci-e 2 is 8x, and like you i git the sound card in last pci-e, but my card runs x16.

Anyone know what level of voltage starts to cause electron migration and ruin the GPUs? 40nm intel CPUs seem to get knackered quickly above 1.45vcore - do 40nm GPUs get ruined by vcore at a similar level? Assuming you have sufficient cooling to keep temperatures under control, is it safe to run up to that sort of level?

Gpu's are very different from the CPUs. They are designed to run hotter-especially fermi.
 
how is fan noise on those coolers ? as i have corsair h 70 with apache fans , so the hole system is pretty quite only can hear the bigboy fan of antec 902

Not strictly true abouit the 2nd slot bering 8x. Pci-e 1 is 16x if you don't put anything into slot 2 and vice versa. That's because those 16 lanes are shared between slot1 and slot2. So you could very likely put your gpu into slot 2 and have it run at 16x also. And the final 16x lanes are shared between slot3 and 4. Your gpu runs at 16x because you have nothing in slot2. The soundcard has no impact as it's using lanes shared between slot 3 and 4.

The combinations for the 32 lanes in the 16x slots are :
1 2 3 4
16x 16x
16x 8x 8x
16x 8x 8x
8x 8x 8x 8x

The Rampage III manual says that in order to run 3 way sli, use Slot 1, 3, and 4. If you do that the 3 way bridge isn't long enough!! Since then Asus tech support have cleared that up and said the best way to do it, is to run your cards in slot1, 2, and 3. However, once you ad a soundcard to any of the 16x slots, your gpu's will drop to 8x, assuming you have 3 dual slot GPU's installed.

Interestingly if you did follow the manuals instructions and uses slot 1, 3, and 4 for your GPU's, assuming you have a case with 8 pci slots, that would leave the dedicated 4x slot free for your sound card. So you could run 580, X-Fi, 580, 580. However you then need to use multiple pci-e bridges to connect card 1 to 2, 2 to 3, and 1 to 3 as the purpose made 3 way bridge won't fit. I suppose the long bridge included with the Rampage III would allow you to connect 1 to 3. And 2 smaller flexible bridges for the rest. Hmmm...

Could you check something for me. What speed does GPU-Z say your 2nd GPU is running at. The reason I ask is you mentioned you run your soundcard in the last PCI-E 16x slot (red slot 4) So I assume you are running your 2nd gpu in red slot 3. That means the board should automatically split the last 16x lanes between 3 and 4, and your gpu should only get 8 lanes. If it gets the full 16 then brilliant. It means the board is smarter then I thought :D

Incidentally, is there a reason why you don't run your soundcard in the dedicated 4x slot. It doesn't interfere with gpu cooling in the slightest.
