Possible to run 64GB over 1600Mhz?

[ChronoDetector]

I heard that if you populate all the 8 DIMM slots on a X79 board with 64GB of RAM installed, it will be unstable at either 1600Mhz or over, is this true? I'm planning to build a server and I would like to have 64GB installed and I'm wondering if I buy a RAM set that is over 1600Mhz, will it be possible to have speeds over that or is having 64GB of RAM at 1600Mhz or under is the limit?

I haven't seen this before (well, haven't tried). What does the board documentation say?

Remember that SB-E chips officially support up to DDR3 1600 so they are just not guaranteeing success with the IMC overclock when you populate all dimms.

I'm running 64GB on an X79 Asus Sabertooth @1866 with a 32GB RamDisk. Oh yes, it is possible.

I can't imagine a socket 2011 server would see any benefit whatsoever for RAM over 1600MHz, considering 2 channel SB barely shows any improvement going from 1333 to 1600 much less over 1600 in anything other than memory benchmarks.

Save your money and stick with 1600.

Well, that's promising. I've used max 32GB memory @1600MHz.

Impressive. What do you use the 32GB ramdisk for?
