Posted June 30, 201212 yr Hi, I spent 2 days messing around with 3x 580 GTX but no way to enable Tri-Way Sli in the drivers... CPU: 3770K Board: Asus Maximus V Formula RAM: G.Skill Ripjaws OS: Win 7 64bit, 32bit, Vista 32 bit Driver: 285, 295, 301 DAWHQ(F)LUCK Just show me some board with space enough that is working - I'm on it ^^ Wanna sandwich my 580 ref between matrix...so 3 slots for 1st card, 2 for snd, and 3rd card don't give a damn... Btw: Manual of the Formula only mentions SLI-config but 3-Way CFX...strange EDIT: List of Z77 mainboard with undocumented feature of 3x SLI by HyperSli Asus Maximus V Formula ASRock Z77 Fatality Pro Edited July 2, 201212 yr by SoF
July 1, 201212 yr Get a board with a PLX8747, without the best you can do is 3-way CF> you only have 16X PCI-E 3.0 lanes there, you can't run SLI with 4x in any slot of the major GPUs

I was running GTX 285 tri sli yesterday on a Z77 Fatality Pro which doesn't support tri sli. Install the Hyper SLI hack for skt 775, use two small flexible bridges and one vey long flex bridge, no problems
July 3, 201212 yr Author That was a VERY helpfull trick - running perfectly now http://www.awardfabrik.de/images/stories/sof_oc_stories/3x_gpu_vantage_46346.JPG

July 4, 201212 yr Author Nice result...saves spending an extra couple of hundred on a new mobo Yeah, thanks again for the hint! For many old benches 1x or 2x is more effective but I am not sure what happens to 3DM03 past 6500 Also there are still categories in the bot for 3x so let's give them a nice bump with IB
November 1, 201212 yr Are any special tricks needed with HyperSLI to get tri-SLI working? I just tried it on my UD3H and could only get SLI working Third slot is never included in the SLI and is only running at x1 ???
November 1, 201212 yr he third slot on the UD3H is routed to the PCH NOT the CPU, the UD5H has it routed to the CPU. What is what you need. You can try asking Pro, i think he got it working at some point.
November 1, 201212 yr I know next to nothing about multi-GPU configs because I spend so little time with them Am I right in saying that Crossfire doesn't care how the PCI-E lanes are connected, but SLI does?
November 2, 201212 yr Yeah. SLI requires minimum PCIe speeds to be working, CF just works on everything.
November 3, 201212 yr I had more "luck" with my UD3H..... at theast that knew there was a third card installed. UD5H only saw two. *sigh*
