I messed up SA1 controls in the latest FW, will post a fixed update in a few hours. In the meantime, grab the working FW here:
https://github.com/1a2m3/...re/SpdReaderWriter.ino
 
Fixed, see one post below

Hi!
I finally got a DDR4 adapter, tried to read some memory. With some modules, software cannot connect to the device. Got "nothing found" in port selection dialog. it tooks some time before I thought of connecting with no module, uncheck  "I2C fast mode" and then insert the memory module. Maybe it's better to detect the device at a low I2C speed?
 
P.S. with 10K pull-up resistors from +3.3V to SDA and SCL lines device connects in both I2C modes

Confirmed, pull up resistors are required for anything faster than standard mode. I'll prepare a new build which will allow connecting to device when fast mode is enabled with DIMM present without pull up resistors to gracefully disable fast mode from the GUI.
