Is it possible to use a version 1.5 avalon controll unit(FPGA) to run a 4 module version 3 Avalon?

I am running a batch 3 module & 3 @ batch 2 modules with a version 1.52 controller (Batch 2, delivered in July).

what do you need to do it? Ive tried to no avail.

I plugged in the ribbon cable & a power cable into their respective slot 4 positions.
I changed the number of miners from 24 to 32.
The holes that attach the heat sink to the bottom place are not compatible. I affixed 1 screw to the heat sink, and tried not to move the miner very much. The module had to be installed at an angle for the header to fit.

I ran it this way for many weeks with the Golden 850 or whatever brand power supply, but I felt nervous about drawing 1030 W from the wall, and bought an OCZ ZX Series 1250W and installed it a few weeks ago. This seemed to be a good power supply and is on the known good list on the avalon wiki. I did (have to) remove 1 of the top plate mounting screws, as the power supply is a little taller than the original.

Today, I received the expansion module for a Batch #2 unit, and I did a swap out between the batch #3 and the batch #2 4th modules. My Batch #2 unit is now an Avalon stock unit, with the replacement OCZ power supply and an Avalon (4th) expansion module.

I also have a 2nd machine. It is a fire damaged Batch #3 unit. I bought a controller, cables, PDU, and thermometers from bitmine.ch. This is all Batch #2 compatible equipment. The PDU is mounted on the original mounting holes. The controller is freestanding. The Golden 850 power supply from my Batch #2 is mounted inside the case. I have a fire damaged module with 6 good sub-assemblies, and I am hosting another Batch #3 module for a 3rd party. So, this Frankenstein unit is a mish-mash of Batch #2 & Batch #3, Avalon & 3rd party equipment. It is currently mining at 256 MHz without the thermometers installed, and using an external fan.

What an adventure.

Sorry when you said you changed the number of miners from 24 to 32, why is that?
I have look around on google and the wiki for some kind of manual for the Avalon and come up empty.

Thanks
