firstly, i like to stress that this is my first time build an SLI setup.

ive mounted 2 msi 560gtx ti on my p8z68 v-pro mobo, together with sli bridge, with monitor was hooked at primary (upper gc) dvi socket of the gc, but windows wont boot (monitor shows no signal).

however the win7 will boot;
1) if i take out the 2nd gc
2) or hook the monitor to the dvi of 2nd gc

however nvidia driver did not detect both gc if i go for 2nd step

what is wrong actually?

not my First time setting up rig, just first time doing sli

ive done the steps u told, but still the situation remains the same.
if both card is placed in pci-e slots, when hooked the monitor to the 1st gc, windows will not boot.

windows will boot if only the first gc is on the mobo, or monitor is hooked on the 2nd gc

hmm...sli bridge may be damaged...hmmm
is damaged sli bridge will prevent sli configuration to be functioning?

ive read somewhere in the forum that sli bridge is not essential for sli, only to boost performance of dual gc to 30-40%.

im using the 1st and 2nd pci-e slot, since the third is too near with psu

my psu is enermax 850w 80% efficiency aaa...

yes both of the cards are not faulty. already checked them invidually.
u may refer to my earlier post.

btw ive checked thoroughly in bios, i cant find any device properties regarding gc. btw how should i check in windows7?

it only shows 1 560gtx ti
emm...could it be faulty mobo? however the pci-e's slot are working if i plug in dvi cable individually (1 gc in slot 1 or 1 gc in slot 2)
