| From: Peter King via talk <talk@gtalug.org> | I haven't had any luck in finding motherboards that would take the old CPU, | RAM, and so on, but your story is inspirational. The case is a CoolerMaster | with lots of space in it, and it would be nice to be able to keep it. What is your old motherboard? CPU? RAM? The oldest i7 with 6 cores seems to be of the Haswell-E generation (eg. Core i7-5820k). The 6-core I7's seem to use sockets with more pins than the common garden variety I7s. This makes for more expensive motherboards and they probably support more memory. Even the oldest 6-core i7s seem to use DDR4. Newer CPUs still use DDR4. So you might be able to reuse your RAM. It might be slower than what you'd want on a new build. The first 6-core 12-thread i7 seems to be Skylake-x. Like a Core i7-7800x. Suitable LGA 2066 motherboards are available and expensive. <https://www.newegg.ca/p/pl?N=100007626%20601299335> I'd love to play with what you discard! It would be newer and more powerful than any of my desktops. If you want a similarly high-end box but for modern times, you can go crazy with a current ThreadRipper or Epyc AMD processor. But you can get quite a lot of power for less, as Lennart has outlined.
