470 sli problem?

post #1 of 5
Thread Starter 
hi guys

just got another 470 for cheap as i wanted to give sli a go.

anyway ive put 2 470's on the board & they booted fine first time so i enabled sli & restarted the system.

no post ? not even bios ***

debug LED shows error code 2A,
which the manual says =
"Initializes different device through DIM See DIM Code Checkpoints section of document for more information"

done usuall checks reset cmos wont work unless i remove one of the cards

checked ram & swap'd single card in each pcie slot & they work.

put a 9800gt in with a 470 to just to check 2 cards works at same time?

new card works in other system's.

im lost ???

anybody else had this?

is it the mobo or the GPU.

ok got it to boot again? but

everytime i shutdown after setting sli it goes back to not posting again with error code 2A

then i have to leave it unplugged for about 20mins & it will boot up fine again.

im thinking that the cards are conflicting with each other once sli is enabled, or something like a cold boot bug.

tried pretty much everything i can. but no joy!

vendor ids match
bios's match
clocks match
both reference cards

i cant try switch cards around cos top card wont fit in slot 2? SB waterblock!

i also tryed my 6950-70 in slot 1 with wc 470 in slot 2 worked fine.

i think its this new card or my mb dont do sli?

i dont have another MB that supports sli so i cant rule that out as the cause.
