I am getting different results on the RampageIVGene board... I run both Aida bench tests and Sandra bench tests on my 3820 before I swapped it for the 4820k, I ran the same tests three times and kept the data with the bios at default and the XMP on my memory set to 2133.
I have tried to achieve the same settings with the 4820k but at bios defaults the 3820 clocks up a bit to 3800mhz and the 4920k comes out to 3900mhz, so what I did was set the bios defaults then enabled XMP to 2133 and clocked down the 4820k with a 38 multi... I ran the same tests I did with the 3820 three times again but I am picking up a 13% to 19% increase in scores, all except PhotoWorxx, where I am scoring slightly below on the 4820k down @ 3800mhz.
the problem here could be my math
but it is more likely that I am running a new Aida64 (IB-E compatible) a new chipset driver and bios, along with a new power supply supplying an 8pin eps. At these freq's I don't think running the old PSU with only the 4pin atx to the cpu would have effected scoring that much?
if I had the 3820 still I could be switching back bios and chipsets figuring out what small increases there be for this particular board, which would probably not be enough to matter still on a score card. What does matter with this IB-E is the IMC taking my 2133kit to 2400mhz and keeping it there all thru my amateur attempts at o/c. Besides... it's not so thirsty (sans the vcore lol) and even if drivers are not seeing that PCIe3.0 it is there surely... I have noticed switching between Gen3 and Gen1 in my bios now has a different outcome or even if I can boot into windows at all with a high multiplier and my antique gen1 card... this wasn't the case with the 3820, it booted no matter where that was set.
-I get better timings with 2133, but that's just my kit... I'd love to see some monster 2800's or 3000 kits on the IMC.

CPUZ and Aida had problems even reporting the cpu until recent updates, CPUZ would not give me memory readings or spd... I am sure it's a driver update away Edited by Butter Chicken - 9/21/13 at 4:51pm
