IB + Z77 + 3 Way SLI...where is it working?


Recommended Posts



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 :confused:

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


Um, you can... 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

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 :D
