New Haswell build in Post Your Pit Test Results Posted January 20, 2017 · Edited January 20, 2017 by terry1966 · Report reply the x99 replacement, whatever it is (can't remember) will probably be like the z170 and have the pci-e lanes controller separate from the bclk so you won't have that problem then. what's the difference in your oc when the bclk is set at 100? and is the extra performance of the nvme drive worth the loss of those htz or is it something that's not really noticeable seeing how it's probably a speed machine anyway. must admit i noticed the extra performance of the nvme drive on my daughters machine just because it and the whole pc was so much faster than my daily pc. things seemed to open nearly before i'd clicked on them it was that different and faster to the click pause then open of what i'm used to.
