Also does anyone know if the kit uses 100 or 125 strap at 3000? Kit model is CMD32GX4M4B3000C15
I was tempted to go for 64 GB but it really does not make sense.
However 2133/2400 G.Skill kits go as low as 370 € over here.
To my knowledge, all 3000 kits for x99 will suggest using the 125MHz BCLK strap. There is word that the 2400MHz RAM multiplier is extremely strong. 2400 * 1.25 = 3000. I owned 4 5960x's. Only one of them, my most recent chip, will do the 3000MHz RAM divider with 100MHz BCLK strap and remain stable. Currently using a release-day ripjaws 4 4x8GB DDR4-3000 15-15-15-35 kit. Command rate 1T. Running VDIMM 1.4, VCCSA 0.85v, VCCIO 1.15v. May not actually need the VDIMM. VCCIO seems to be helping keep 1T stable.
Currently working on 4700MHz cache, tuning in the voltage required. 20 minutes stable so far on AIDA64, 1.3 volts (Been increasing by steps of 1/256 volts [0.00390625]). May or may not go down to 4600MHz cache. Core will probably have some room to expand, currently 4700MHz core @ 1.344v, 1.95v input. Probably need more input to be prime stable. Already prime stable at 4600MHz core.Edited by ssateneth - 2/12/16 at 10:49am
