Through an idea by Jake Crimmins at Corsair of using the EVC for programming the SPD of DDR3 memory modules, I’ve started working on an implementation of such a feature in the eVc software. I’ve tapped in to the memory SMBus interface and successfully read/written SPD data, simply put it works great. Currently I’m working to make the interface more user friendly as it’s now just all about reading/writing hex bytes to the correct registers.
All you need to do is to connect the EVC to the SDA/SCL pins of the memory slot and you can start editing the SPD of your memory. I achieved this through a dummy DDR3 dimm pictured above. I could then read and write the SPD using the EVC software using the custom read/write menu option. Right now I’m developing a more user friendly interface, it’s beginning with a full readout of the SPD from a Corsair Vengance Pro 1866C9 module (CMY16GX3M2A1866C9) is shown below.
