Ah good. I figured that was probably the case as nobody had mentioned
to the contrary anywhere, but thought it was best to check. Reading the
forums, it's hard to tell if there's anything particularly different
between the P9X79-named products and the Rampage IV series in terms of
general oc potential, procedures, gotchas, etc.
It was staggeringly easy to do with my Maximus IV Extreme, but this is
my first X79 build.

Yep, that certainly seems to be the consensus. I was just wondering if
there were any specific things that would help when using 64GB, especially
at 2133. So far I found the following in the various ASUS guides, etc.:
VCCSA LLC: probably needs be High or more for 2133, with VCCSA VID of 1.2,
though lower is better if possible.
VCCSA Current Capability: likely needs to be 140% for 64GB.
DRAM Current Capability: probably needs to be 130% for 64GB or > 1866MHz.
DRAM Timing Control: may need to use 'Raw MHz Profile' and might have to
add 1 or 2 to DRAM Write Latency for 64GB.

That would indeed have been ideal, but alas such was not available (very
few places sell the 64GB kits here, and the ones I did find only offered
much lower speeds). There was also a crazy price premium on the 64GB kits
which could not be covered by my client, so 2 x 32GB kits it had to be.
I'll see how it goes. If this board has anything like the quality of the
Maximus IV Extreme, I think it'll be just fine, perhaps with a bit of
effort required. On the MIVE I didn't have to do anything at all to obtain
16GB @ 2133 (4 x 4GB) with the CPU @ 5.0, very impressive indeed.
I expect what probably will require some extra tweaking is when the other
devices are added, ie. SAS RAID card (LSI SAS3082E-R), about 6 disks, a
second 256GB SSD, and an 800MHz GTX 460 for CUDA, ie. the extra power
loading. The system will be used for After Effects CS6, though I'll
benchmark it first for my site info (Google for "Ian PC Tests").
I plan on initial testing with manual/fixed vcore, etc., to get a feel
for typical idle/load voltages, temps & suchlike. Could easily be the
attainable oc is limited by temps rather than what the CPU could really
do (ie. as I'm only using air, albeit the Phanteks with 3 fans which is
supposed to be the best atm). I'd like to keep load temps below 75C.
Even without an oc though, I was impressed to note the system is quicker
than my 2700K @ 5.0 for CB10, and *almost* as good as my Dell T7500 with
2x XEON X5570 @ 3.2 (that was unexpected).
Thanks!
