Kingston Fury 64GB DDR4 3200 CL20 RAM working in XPS 9710! (with SPD mod)
I managed to get the Kingston Fury DDR4 3200 CL20 RAM working in my new XPS 9710!
It appears that the XMP profile, which is stored in the SPD EEPROM at bytes 0x161-0x1ff on the RAM module was the culprit in causing the dreaded 2 amber and 5 white "invalid memory installed" POST error.
Zeroing out the XMP profile bytes did the trick and the RAM was recognized and the laptop booted up!
I used the i2c-tools in Linux to zero out the XMP bytes. I was able to write to the SPD by using a SODIMM to DIMM module to insert the laptop memory into a desktop. The XPS 9710 has a BIOS write lock on the I2C bus, so you need to use a desktop to do the modification. I'll post a more detailed write up on this on my blog. I'm sure this voids the warranty of the Kingston ram... and a lot can go wrong, so if you try this, be careful.

Here's a few benchmarks / screenshots / links :)
