Getting 64 gb ram stable.

[RJF049]

I am using a rampage iv extreme motherboard and 64 gb of matched ram. Do I need to plug in the 4 pin power at the top of the board or the 6 pin above the pci slots to make sure the ram has enough powr?
Also, should I expect anymore than 1333 MHz running this amount of ram?

ram usually gets enought power through the Ram slots..

the 6pin is for additional gpu power if you have like a fancy quad sli/cfx rig. The 4pin should give some more juice to the cpu for more oc'ing. I dont think you need them.

RAM don't use that much power, very minimal, The slot itself will do, but if you have a 3 or 4 power hungry cards, there is a chance you might burn the 24 pin connector on the mobo so plugging it in should be what you should d0

 Thanks!

what RAM, what RAM kit and what specs?

You should get full speed out of that chip and board. Not 100% sure though. 3930k is sandy, so possibly not.

Well its 3970x

Several forums have mentioned that the EZplug2 floppy power connecter needs to be powered on the rampage iv if all 8 dimm slots are full?

doubt it'd be a power issue as the RAM is rated 1.65v and the IC is 2.0v. but usually

comes down to the integrated memory controller (IMC) onboard of the CPU.

might try 1866 at 1.6v and use 2133 timings on a stock (non-overclocked CPU) with

all 8 saddles full. if this has some stability, then move to 2133 and add +2 to latencies

on 1.60v. retest stability. either OCCT 4.4.0 or Memtest86 (preferred)

 

the extra power for wacky voltage increases in CPU voltage and RAM voltages. your

stock and below stock voltages are not a drain at this time.

 

i've gone way over on CPU/RAM voltages ands never had to brake out another

CPU/GPU power harness. me thinks there are other issues.
