Share your DDR3 Memory Overlocking results @6-6-6-x timings
Members can post their Intel based DDR3 memory overclocking and scaling results for 6-6-6-x memory timings.
This thread is for everyone to be able to share their memory overclocking results, tips etc for the specific timings listed above ONLY. If you have problems overclocking your memory in general please start a new thread in relevant forums for AMD and Intel memory listed here http://i4memory.com/f2/.
Some suggested (not required) apps to include in screenshot:

I'll start off with latest
testing KHX2000C8D3T1K3/6GX @ 6-6-6-20 1T timings
Memtest86+ v4.10 scaling:
Windows max 32M Pi @DDR3-1850Mhz 6-6-6-20 1T, max 1M Pi @DDR3-1880Mhz 6-6-6-20 1T and validation @DDR3-1893Mhz 6-6-6-20 1T.
max 32M Pi @DDR3-1850Mhz 6-6-6-20 1T
max 1M Pi @DDR3-1880Mhz 6-6-6-20 1T
max validation @DDR3-1893Mhz 6-6-6-20 1T
CPU VTT = 1.50v
VDIMM = 1.76v

Quick runs seeing as 2 modules out of 6 can do 900mhz 6-6-6-20 1T at 1.7v memtest86+ v4.10 and the other 4 modules only do 894mhz 6-6-6-20 1T at 1.7v memtest86+ v4.10, then for just single 32M Pi test, 6x2GB Super Talent 2200C8 falling in around:
Bootable at 879Mhz 6-6-6-20 1T at 1.66v with CPU VTT 1.3875v
879Mhz 6-6-6-20 1T at 1.7v with CPU VTT 1.4125v
885mhz 6-6-6-20 1T at 1.7v with CPU VTT 1.425v
889mhz 6-6-6-20 1T at 1.72v with CPU VTT 1.4375v
894mhz 6-6-6-20 1T at 1.72v with CPU VTT 1.44375v
900mhz 6-6-6-20 1T at 1.70v with CPU VTT 1.425v

Best three modules out of two Hyper IC kits 3x2GB @ Rampage III extreme, I7 920
vdimm 1.71, RAM on Air, CPU on Water
I might try higher vdimm later.
I do not tweak it very carefully:
all voltage except vdimm is set randomly;
most sub-timings(including RTL, except for tRFC and CR) are using R3E auto.
186x10=1865 6-6-6-18-1T-72 y-cruncher 250M/super-pi 32M
vdimm 1.71 vtt 1.425
tRFC=72 at this timing and frequency has ~1/3 chance to fail y-cruncher 250M.
tRFC=82 100% pass y-cruncher 250M.
177x10=1775 6-6-6-20-1T-72 LinX 20 loops
vdimm 1.71 vtt 1.425
In my case, Linpack is among the toughest and most efficient stress test.
Prime95 x64/y-cruncher are not as efficient as Linpack.
Hyper PI 32Mx8 is much weaker than all three above.
A mixture of two Hyper IC kits:
one kit of STT 2000C7 last year, very likely to be MNH-E; another kit of STT 2000C7 early this year, should be MGH-E. The SPD information of two kits are totally different, however, mixing them together works well.
Got these 2 kits each at the price over $400. Don't know how well current cheap 2000C7 will do.
The new kit is slightly better than the old kit.
