5820k, overclocking DDR4, need help
I have an old 5820k and some Corsair Vegneance LPX 2666Mhz. 16GiB 4x4GiB, CMK16GX4M4A2666C that I'm having real trouble overclocking. Anything over 3000 Mhz. results in a no-boot condition that requires a dozen resets to get back into the BIOS to fix. I've tried cranking the Vdimm to 1.45V and it didn't help.
The primary timings for this set are not good: 16-18-18-18-35 @ 2666Mhz./1.2V (the primary set of XMP setting) and 16-18-18-37 @ 2800 Mhz./1.35V(the second set of XMP settings). So far I've been working off the second set of XMP timings with command rate 2T for my attempts at overclocking at speeds >= 3000Mhz. Do the secondary and tertiary memory timings also have to be adjusted? Should I try increasing the primary timings?
