Right now for me

713 W total for 2 S3

Frequencies:

1-->430 GH/s stable, 212,5 Freq, 41/42 temp
2-->439 GH/s stable, 218,5 Freq, 46/43 temp(cant run at 212,5 i get xx and -)

I will keep them that way just to test, i dont like the OC its nos stable  Huh
Huh... weird that under clocking causes you to see "x" and "-".  Even weirder that running that same unit at 218.75 is stable.  I have 1 unit that just simply won't run stable at stock clocks, but gets a pretty respectable 425-430 at 212.5.  Another runs perfectly happily at 218.75 getting 440.  Neither will over clock at all.

Hey guys...Please, hook up all your 4 PCI-E connectors... Wink

You never know what the PCB designer had in mind...but there is a REASON for these 4 connectors...like traces current(s), parallel (redundant) supply...etc...

Mine S3 are running @ 504 / 250MHz ...& @ 475 / 237.5Mhz now... Grin

I ran my S3s with all 4 connectors and it made no difference.  They simply will not handle any kind of higher clock frequencies.  One of them doesn't even manage to hash at the stock clocks and has to be run at 212.5.

yeah both of mine prefer 212.5 over any other number, so why fight it.  they get 430 at 328 watts
