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.
