Can you suggest a method to find heavily rowhammer affected hardware? Only by
testing it, or are there some chipset IDs ranges or dmidecode info that will
pinpoint potentially affected machines?

I have worked with many different systems both on running rowhammer attacks and testing defense mechanisms. So far, every Ivy Bridge i5 (DDR3) that I had access to was susceptible to bit flips - you will have highest chances with Ivy Bridge i5...
