Founder Brian Posted April 5, 2013 Founder Share Posted April 5, 2013 So officially the Asus Maximus V Formula doesn't support Tri-SLI, just Tri-CrossfireX and SLI (2-way). The reason I guess is due to nvidia not being able to officially utilize 4x speeds (e.g. it does 8 x 8). The extreme version of the Maximus V supports tri-sli but that's about $400+ for that board. One way around it is to use a program called HyperSLI it's a simple install and click program. Just make sure you have a processor that has VT-X (although software emulation is also possible) and 2 mini bridges + 1 long bridge to connect the 3 cards. In my case, I connected 3 GTX 680 cards (2 680 SC signature 2 + 1 680 SC, all EVGA). It doesn't seem like the lack of bandwidth is hurting the performance too much in games or benchmarks on a single monitor at 2560 x 1440.

Khenglish Posted April 5, 2013 Share Posted April 5, 2013 OC that CPU more! I've run my laptop higher than that. Might want to OC BCLK some for more PCI-E bandwidth since 2 cards are running x4. IVB will get over 10% unlike SB. Quote Link to comment Share on other sites More sharing options...
Founder Brian Posted April 5, 2013 Author Founder Share Posted April 5, 2013 Will give BCLK a shot although the CPU is at 4.5 GHz 24/7. Any higher requires a big jump in voltage for some reason. Quote Link to comment Share on other sites More sharing options...
EC51 Posted May 1, 2013 Share Posted May 1, 2013 Nah... 3770K @ 4.5 is awesome. 4.5 is the sweetspot for 3770K in terms of power, heat and performance, IMHO. Quote Link to comment Share on other sites More sharing options...
skyn3t Posted June 3, 2013 Share Posted June 3, 2013 My 3570k need 1.2v for 4.5MHz and it has been like that since day one it can do 4.7MHz easy but i find my self 4.5MHz very comfortable with low temps. Quote Link to comment Share on other sites More sharing options...
jackparkyy Posted June 5, 2013 Share Posted June 5, 2013 can you not just use a tri-sli bridge instead of two small sli bridges and one long sli bridge? Quote Link to comment Share on other sites More sharing options...
Founder Brian Posted June 5, 2013 Author Founder Share Posted June 5, 2013 can you not just use a tri-sli bridge instead of two small sli bridges and one long sli bridge?Nope, length and spacing is off. Sent from my GT-N7000 Quote Link to comment Share on other sites More sharing options...
Urobulus Posted July 6, 2013 Share Posted July 6, 2013 Yeah but can't you ''bend'' one since they are usually very flexible? That would take care of the spacing. Quote Link to comment Share on other sites More sharing options...

Typhrus Posted January 13, 2014 Share Posted January 13, 2014 Hi OP,Just to clarify you are running three GTX680's in SLI with a little bit of software to get the third running. And this works well? I was thinking about doing this when I saw your post. What are the gains on having a third card? What are you loosing due to two of the cards going down to 4x?Thanks for your help!

Dark Session Posted May 21, 2014 Share Posted May 21, 2014 Gains on a third card are almost non existent, microstuttering could get a smaller problem but thats all. CPU limit is a bad thing ... Quote Link to comment Share on other sites More sharing options...

CPU limit is a bad thing ...Not true, the third card scaled quite well when I ran 3 x 680's in the OP. Microstuttering wasn't an issue I noticed either.

j-lor Posted March 26, 2015 Share Posted March 26, 2015 Hey Brian im trying to 3 way sli on the same board you had would i be able to do it.
