Z270 Taichi overclocking

Yes, thanks for posting your experience.

When I saw the thread title, I was worried it was an X99 Taichi owner with a Broadwell HEDT CPU, complaining about the OC potential. If you really want to OC on an X99 system, get a Haswell HEDT CPU. As long as you can that is, Haswell HEDT processors will be EOL soon.

Your OC is great, deliding is a big help of course, once you're at 4.8GHz or beyond. The VCore you can use is great, I never tried pushing mine that low. With no delid and air cooling, 4.9GHz on an i7-7700K is difficult to keep cool during stress testing.

We had a guy here that had an i7-6700K at 5.1GHz, with a 1.52V VCore, no delid I think, custom water cooled, with the Z170 Extreme7+ board.

While I've read about all the contempt in some forums for Kaby Lake processors due to their lack of IPC performance improvement, the stock and Turbo clock speeds are high, and can almost reach 5GHz with a decent board without too much work. If you can reach ~5GHz at ~1.4V VCore, and 4.8GHz at 1.38V on air, delidded, that is great.

About the memory speed, once you get beyond 3600, 16GB will be very difficult to maintain. The memory controller may not be able handle it, and the shielding and placement of the DRAM traces on the board are either not practical, too expensive, or both. You might get close to 4000 with only one 8GB DIMM, or two 4GB DIMMs. Nice tight timings at 3600, in real terms I doubt you'd get any performance benefit going faster.

Thanks for sharing!
