More hashing blades possible?

When the S3 starts up i see what looks like it is maybe searching for up to 4 boards? Has anybody else noticed this and can it be taken advantage of using one controller to control double the hardware?

You got it wrong.It sees only two blades but it's looking more chips than 16/blade.I think it is possible to chain two boards together to get total 30 chips per chain.Two chips have to be removed to chain them easily.Somebody did that with S1 blades (think it was sobe-it) but I don't know how well it really worked.
I have tried with 4 blades as controller (controller chip) has 4 uarts,but firmware only finds 2.

I did do it, it ran faster BUT not as fast as it could because we were having problems with speed of a single blade using usb to uart converter. a single blade would hash from 25gh to 45gh and the mod I did it ran 55gh to 80gh. It may work if its done using the regular controller board but you would have to edit the firmware for the right amount of chips and time out setting. I know this because I ran a s2 blade on a s1 controller and it would get ~95gh but would lock up in about 5 min.

Thanks for the information.I cannot code so I'll forget that idea.And it is also much easier just add two more connectors to regular controller.If there were firmware to support them.

there really isn't any coding needed. all you have to do is basically edit numbers like when you over or underclock an ant s1 or s3. I haven't found where they are so I haven't edited them yet.

Yea if it was an S5 some of the firmware allows 4 blades.  But S3 to my knowledge none of the firmware allows 4.

I don't see this changing at this point.  Not really anyone that is going to spend the time making firmware for S3 to allow this I don't think.

I know this.That's why I'm going to start a new project with altera based controllers.I still tweak these pic controllers for my own fun.I'm currently building a casing for 8 S3 blades.Driving it with cp2102s and cgminer.No fan speed control or anything but having 2TH S3 based miner is cool!
