Hey there fellow Bitcoiners,

So I recently acquired a storage unit, at auction, that while unpacking I found to contain a brand new, or VERY gently used Antminer R4. I've gotten it up and running but was wondering if anyone had any old versions of the R4 Firmware that were prior to the releases that have the Auto-Frequency only settings (Firmware currently on the machine is from 11/2018 and lacks the advanced settings tab). Friend of mine has several R4's that all have older firmware that allows the user to select the chip frequency from a drop-down list.

I know after doing some research that these were known to have a high failure rate (reasons stemming from what I assume to be heat-related looking at the specifics of lots of documented failures) so my hope is to find someone who has the gzip archive as it is no longer available from Bitmain - I want to run this miner at the slowest possible core clocks and really use it as a space heater as the colder months are right around the corner here in the northeastern USA!.

If anyone has that FW, or - if anyone knows how to enable the "Advanced Settings" tab in the newer R4 firmwares, any help would be greatly appreciated!.

Little more info in case it helps - controller is a XILINX Zynq board (Bitmain's site had a couple of possible boards listed).

Thanks in advance, cheers!

Hello, i have all you need, install this firmware : https://file12.bitmain.com/shop-product/firmware/Antminer%20R4/Firmware/0072018111915190019606xL1e6L0640/Antminer-R4-xilinx-201811121649-autofreq-user-UBI-NF.tar.gz
