Those timings aren't worth it at all. 14-31-31-50 at 4285.6 MHz is equivalent to about 8.7-19.3-19.3-31.1 at 2666.6 MHz. Sure, it's a record, but I want to see DDR3 frequencies with DDR timings more. He got a good CL and tRAS, but the tRCD and tRP really aren't anything to write home about.

EDIT: Here's stock timings for these sticks for comparison:
11-13-13-35 at 2666.6 MHz

EDIT: Hattifnatten explained why timings matter below this post.

If that made any sense, hooray, I managed to write something remotely understandable while half-asleep sleepysmiley03.gif

Guys ...this are not of the shelf stuff ,this are some samples that were individually binned from 600 modules if i remember correctly for one purpose only VALIDATION at the highest frequency possible=you can't compare this timings for daily use

Hynix MFR-PBC (High Leakage) 4GB Single Side DIMM



if you still interested here are the original threads

Don't expect to get a pair of TeamX 2666c11 and get above 3000~3200 or even 2933 on an average Haswell/mainstream motherboard/ air, also you have to have proper (binned) CPU with a killer IMC + skills

Awesome job John Lam , Splave and Nick Shih thumb.gif
