Description

Everything was perfect on my computer life, till I decided add a second vídeo card on my build. Despite read all the warnings about de SLI setup, this is something I had to go through.

Now, with more knowledge about the subject, I feel a mix of feelings, some times very happy, when SLI does work, and some times a bit sad when it doesn't.

My concern regarding the temperatures is because I live on a very hot zone. I have changed some points after added the second card in order to improve the VGA’s temperatures:

  • 1 - Applied the EVGA Thermal Mod on both cards, with Arctic MX4 thermal paste, and updated the BIOS (new fan curve);
  • 2 - Changed the case stock fans with Corsair ML series;
  • 3 - Up side down my PSU (not sure if improved, but looks nicer);

After these changes, on a 30ºC environment, the temperatures are OK with the cards. 80°-82° on stress tests and 65°-70° on games, regarding the top card. Usually the bottom card runs about 6º-8º cooler than the top. This kind of VGA cooler (ACX3) throws too much hot air into the case.

References that the temperatures are OK:

Now, with the situation under control I want to enjoy my games! The system have tons of game power! However not sure if I will continue with SLI on my next upgrade, mainly because I have seen a very poor suport on last games.

Cheers!

Oh that's beautiful! I am also thinking about SLI, though not in my current room. It's a small cube essentially and if I ever had to close my door I would be sweating. Maybe if I had the "large" rectangle room which is roughly twice the length of my room there would be more space to disperse the heat. Still concerned about that route though.

Thanks! Large room is better, also, my large space inside the case helps a lot. I wish, sooner than later, move to a room with air conditioning. Then all my problems will be gone! :-)

I'm pushing the 23.8 version of that monitor with one Gtx 1070, I'm jealous! Nice build!

Actually my Dell monitor was shipped but not arrived yet. For now I am using the Benq XL2720Z. After read all reviews of the Asus Rog 34 and Acer Predator x34, my primary choices, I decided by this Dell till we have more options available on the market. Are you enjoying your Dell?

It's awesome, 1440p is so sharp at 24in but it's not fun to do office stuff on. It came perfect , no dead pixels and with setting adjustments looks great!

Reference cards are the best solution for SLI unless you want to liquid cool

I am planning to change the VGAs Open Air Cooler by the Hybrid Cooler. Do you think it is a good plan in order to improve the VGA's temps? Thanks for the advice!

Heck yeah thats a good plan! I personally just prefer reference cards but my brother only uses hybrid cooled cards. His 980 ti hybrids usually idle in the low 30s and run in the mid 50s while gaming. And his cards are stacked right on top each other, you have an empty slow between yours so you should see even better temps!

Damn nice build! +1 The problem is the slot spacing on that board - my dual FTWs only get to about 74 degrees max, but there's some more breathing room between them. I must admit I too have an inkling of buyers remorse regarding the second card. :-/

Why did you opt for 1080 sli instead of a single Titan x(P)? Otherwise great build. cable management is nice and it looks great.

You are right my friend. Nowadays it would be my choice. However it took me six months to build this machine. At that time I was blind by the idea of SLI. Anyway, when I play games that scales well both cards, the performance is insane! No regrets, (mostly) ;-)

Ok thats pretty cool.

The biggest thing that most people forget Is that even if SLI isn't supported by the game PhysX most likely is. With a second card and the PhysX set to be ran off the second card allows for max PhysX settings and the first card to be used just for video rendering. I have run dual card setups from both manufacturers from the begging and will never run single card application if can get away with it. I have had much more success and fun with NVidia vs AMD in this respect. The result is always a richer more detailed scene and better framerates when it scales well. I have not had an issue with either camp unless it is flat out not supported by the game in question and then it is only a :( because I cant use it.

Thanks for sharing, feeling better now! I like your build too, great job! Cheers!

I live in a cold environment and look to build a SLI system myself. I look for a case like the Silverstone Fortress FT05 to avoid the top card being hotter than the bottom one. Could you explain a bit which games seem to run bad in SLI and if it's any hassle to simply disable SLI for those games? I imagine I can easily have SLI enabled by default and just disable it in the GeForce controll panel for those games that does not, and thus run everything well :)

ps: I love how your chair matches your case ;)

Your concern is very valid, and you have the opportunity to choose the right type GPU cooler to your setup. Please, see this video in order to understand the diferent types of GPU coolers. I don`t recomend the Open Air Cooler (same as mine) for SLI, simply because the Top card get the hot air from the Bottom card, and also, one or two slots are not good spaces for this type of cooler. You can disable the SLI anytime you want, however with Open Air coolers the space limits the air flow anyway. For SLI I do recomend the Blower-Style or Hybrid in order to maintain good temperatures inside your case and all components. Good luck with your build! Cheers!

Ah, with Silverstone FT05 there is no top or bottom card. The entire motherboard is rotated 90° to allow the cards to hang vertically instead of horizontal. With a MB that then has spacing between the two cards it should be smooth to use Open air coolers. Blower style is LOUD - and as I center the entire build around making it as silent as possible. I'm looking at cards that run fanless on idle, and as quiet as they can while working. (The build will sit in my living room and be turned on 24/7 - which is why it can't make itself heard). Thanks for good feedback :)

why you go with Dominator DDR4-3000 when Sabertooth just can reach 2400 maximum? OC maybe?

It does support these memories with the XMP profile turned on. They run at 3200 Mhz very stable. When running XMP at DDR4 3200 MHz or higher, the system’s stability depends on the CPU’s capabilities. You can find the memory QVL on the ASUS support site of this MB. See below my OC configuration, it is stable for months now:

  • O.C. type: XMP (Target DRAM 3200 MHz, DRAM Voltage 1.35).
  • CPU Core Ratio: 46.
  • CPU Voltage: 1.330 (Adaptive Mode).
  • LLC: Level 5.
  • Target Cache: 4100 MHz (default).
  • VCCIO: 0.976 (default).
  • System Agent: 1.08 (default).
  • Power Plan on Windows: Balanced.
