Yep!

Awesome. I thought that was the case as the holes seemed to be the same for the screws. Gonna go pick one up.

Can't wait to get all the rest of my wc gear so I can get my 900D build up and running

Hey everyone, I recently set up my tri-SLI 780 Ti Classified rig and am absolutely loving it. The cards are crazy fast! My concern is, my primary GPU is reaching ridiculously high temps during benchmarking or gaming (120Hz surround). I am on the stock ACX cooling on all three cards temporarily, but, they are in an open-air test bench case, next to a wide open window with all fans at 100% and an industrial floor fan helping to promote airflow. GPU1 will get as hot as 95C during Heaven benchmark on extreme preset. On Crysis 3 it doesn't go past 91C which isn't too bad but still higher than I'd like to see. I thought having the fans cranked at 100% would make a difference but heck, it's still nearly hitting the max GPU temperature with the fans consistently at 100%. I know this is simply a factor of having the cards sandwiched in 3-way SLI, but does anyone have any ideas? I can't seem to find anyone else with more than two of the regular 780 Ti Classifieds in SLI on stock cooling. Core clock, memory clock, and voltage are all at stock settings as I'm afraid to do any OC'ing to these with the temps that GPU1 is reaching. The other two GPU's stay at much more reasonable temps. Any help is much appreciated!

Do you have any non conductive TIM sitting around? If not, shoot me an email and I will shoot you a tube of MX-4 over. It may just need a little TIM loving as it isn't the most beautiful Tim job in the world that comes from the factory.

P. S. What are the other Temps?

I just did some more testing and it appears that during gaming (Crysis 3 in surround was what I used to test it), all three cards will start out at 1163MHz boost clock, then my primary GPU (GPU1) will slowly creep towards 95 degrees C, it will hit 95 then all of the cards will slowly throttle down to an equilibrium of roughly ~1020-1036MHz. GPU1 will stay at 95C throughout the entire gaming session, and it will just keep the clocks of all the GPU's down to their stock, non-boost clock. I'm really hoping that it is just a faulty card, but my instincts are telling me that this is the downfall of sandwiched GPUs in SLI. I always read that the reference design coolers are better for 3-way or 4-way SLI, but I thought that it wouldn't be as much of an issue with the fans all at 100%. I'm learning the hard way why mostly everyone uses waterblocks for high-end systems.

Worst case scenario I'll just return these classifieds and go with quad-SLI reference 780 TI's. Although, I do love the classifieds. They look great in my case/with my rig in general. I've read a lot of mixed reviews on how well the 780 Ti Classifieds overclock, but when I was using just a single GPU it was overclocking very well, even on the stock BIOS. Well, I hope someone can chime in here with some advice. Thanks guys.

Hey there, thanks for the reply - I was just typing my second post out before I noticed yours. Thanks for the offer man, I really love how helpful this community is. I actually do have a massive tube of MX-4, I just put this PC together a few days ago and I used MX-4 to paste the CPU. Hopefully you're right! Oddly enough, before I moved the computer into the second room (which has MUCH more airflow and is next to an open window + industrial floor fan lol), I believe that I didn't see the temps go that high. I could be wrong and will need to do more testing to make 100% sure but it sure does seem odd that GPU1 is getting THAT hot. It will actually hit 96 for a very short second before it throttles the clocks down and hovers back to 95.

GPU1 Max: 96
GPU2 Max: 79
GPU3 Max: 56

I wish all of them would run as cool as GPU3! tongue.gif


Edit: Also, right now after just idling for a bit with the fans at 100%, GPU1 is at 33, GPU2 29, and GPU3 26. Although I'm not sure if this matters much since the GPU's are just idling.

Try repasting it, and see if it helps. I would definitely try that, as there are only a few screws and it only takes a few minutes. If nothing else, you only burn a few minutes of time before sending it back. Have you considered selling them? You may be able to get a few pennies to help pay for new cards.

It is known that in SLI the top card run hotter. I've experienced it with both 580 and 680 SLI on air. About 10 to 20°c at worse.
That's why I goes back to watercooling and will never go back now, I just can't handle to see a temp higher than 65°c.

Other pictures of my watercooled rig can be found here:
http://www.overclock.net/t/1430077/corsair-750d-owners-club/3610#post_22034055

Currently i'm running the Classy 780 (non Ti) on 1380MHz @ 1.30V
Temps are around 45-50 degrees celsius while playing BF4.

Owned may cards in the past but this card is the beast!

That's really nice, welcome. I love the blue color of the tubes against the black. Please post a gpuz validation when you get a chance. Thanks.

I use a Corsair TX750M for only one Classy 780. OC'd to 1380@1.35V. My CPU (3770K) is OC'd to 4,7GHz.
Should i upgrade to >1000W PSU to get more volts in my GPU or is the 750 watt enough?
Oh, the TX750 provides 62Amps on the 12V rail.

Lets say
TDP 100% = 600w. With gpushark (Detailed mode) you can see current used in %. You maybe use about 100% = 600w. And out of the wall you are taking a total of 800w so system use 200w

I would say that your 750 needs an upgrade. on 100% load its 750w minus 19%/15% = 607,5/637,5 - (115Vac/230Vac) total watts.
