I could use some help with my RIVE and RAM got from RMA

I have an Asus Rampage IV Extreme motherboard with i7 3960x.

I was running 32gb 8x4gb Corsair CMT16GX3M4X2133C9 ram. I was just using the XMP profile and ran fine. My ram started to have page fault errors so it was RMAed. I got back 64gb 8x8gb CMD64GX3M8A2400C11. When I selected the XMP profile now when boots I get PHASE0_Exceptions or Page Fault errors and other random errors. If I change the speed to 2133mhz it seems to boot fine.

Since this is 2400mhz ram I would love to run at that speed. I haven't even messed with settings other than select the XMP profile and worked. Seems this 2400 mark isn't that simple.

Am I missing something or not doing something right?

My MB is using bios version 4901

I haven't read them all in detail, but's there should be the info you need.



This is from the "IVY BRIDGE-E EASY OVERCLOCKING GUIDE – THE LISTY/WORDY EDITION" by Raja from Asus (#2 in the list):

1) DDR3-1866 is supported as a stock speed. However, it is only supported with one DIMM per channel. If all slots are populated, then the maximum supported memory speed is DDR3-1600. Both situations are likely subject to memory timing, too. Intel usually makes this information available in their white papers.

Supported speeds are those the processor can run without needing any kind of voltage adjustment. Anything faster than this is defined as overclocking and quite obviously, may require adjustment of voltages and memory timings to work.

The idea then is to select a memory kit that suits one’s mindset. If plug-and-play operation is desirable, then it would be wise to select memory kits rated no faster than DDR3-1600 or DDR3-1866 (depending upon density).

If one is inclined to tune a system manually, then purchasing a faster memory kit is possible. Bear in mind that performance gains from running faster memory are minuscule in most applications. If budget is constrained, or you’re simply looking for good performance return for expenditure, then spending excessively on fast memory kits is ill-advised.

Hi rmilyard

64GB of ram is not plug and play and you will need to adjust some voltages.

On the extreme tweaker tab try these settings:

Enable XMP

1) CPU VCCIO voltage 1.20v - 1.25v
2) CPU System Agent voltage 1.20v - 1.25v

F10 and Enter to save and exit

If no success

3) Raise the Dram voltage 0.05v

How does she go?

Where do I find these 2 settings?

1) CPU VCCIO voltage 1.20v - 1.25v
2) CPU System Agent voltage 1.20v - 1.25v

I am not seeing them I think. I did select XMP.

Well, on my board they're located on the extreme tweaker tab down near the cpu core/cache voltage.

In Arne Saknussemms guide there is a link to a guide on doing the RAM settings (Arne's guide is for the IV, while the settings guide is for V. I would expect it's done the same way on boath boards though as he has linked to it)

Still a no go. I get errors at 2400 in memtest64 in about 1-2 mins.
