about i7-4960x‘s memory write benchmark

[seawolf1 0]

hello，i found a very strange problem about memory write benchmark，it's very low....

question is，this is normal or not or bug？

[Fiery 401]

It could be due to a pecularity of the IMC (integrated memory controller) of your processor.  Maybe the benchmark hit a bottleneck, or there's a memory interface instability at DDR3-2400 using the seemingly strict memory timings you've configured.  Can you please post a similar screen shot, with the memory running at DDR3-1866?

 

 

Thanks,

Fiery

Thanks for your reply，1866 seem to be normal，i’m confused......what can i do....

just saw this old thread, and wanted to share my experience. as almost all of x79 mobo with ivy-E cpu having this very same problem at that 2400 divider. there is no solution found yet. 2133, 1866 seems to work fine.
