Live MB OC Report :: ASUS Rampage Extreme

[cstkl1]

Hey there just moved from P5Q-Deluxe (Considering the CL4 bandwidth issue) to DFI-UT-X48-T3RS and then back to Asus: Rampage Extreme.

Actually I've got both 3 main Micron IC's memory module all from Crucial. They're:
CL12864BA1067: Curcial Value CL7-1066 D9JNL
BL2KIT12864BA1336: Crucial Ballistix CL6-1333 D9GTR
BL2KIT12864BE2009: Crucial Ballistix CL9-2000 D9GTS

From my rough tests so far...D9GTR runs without any problems.
With this kit I can get
CL7-6-5-18 1T tRFC 48 1800Mhz 7/24 Stable @ 2v
CL6-6-5-17 1T tRFC 48 1600Mhz 7/24 Stable @ 2.08v
But no luck with 8-7-6-21 2000Mhz even @ 2.15v.

While D9GTS has really impressive results:
CL9-9-9-24 1T tRFC 60 2000Mhz 7/24 Stable @1.84v
CL7-6-5-18 1T tRFC 60 2000Mhz Dual PI 32m Stable @2.09v BIOS

But D9JNL's result is really disappointing:
CL7-7-7-21 1T tRFC 110 1664Mhz random freeze @ 1.9v
Any higher voltage will result in either memtest error or random freeze.
I was wonderin if there are some compatibility issues related or so?

For my own question: Does somebody know how to adjust DIMM VTT? Seems the DRAM vREF setting isn't doing a thing to DRAM VTT adjustment?

for d9jnl
the freeze issue i solved it with nbb dram vtt +12.5 and channel a/b at +25

theres other test to show the adjustment of vtt needed and also skewing of cmd/clk/ctl
so far for myself
cmd is 1N-2N related with cpu vcore for orthos small fft
clk is nb gtl/voltage...orthos blend then custom min max 4096 fft
ctl is dram vtt related.. +nb voltage related...with orthos blend then custom min/max 4096
