Members can post their Intel based DDR3 memory overclocking and scaling results for 6-6-6-x memory timings.

Objective:
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/.

Notes:

1. Please be sure to post your system configuration used, memory brand & model and voltages used.
2. For screenshot capture windows Print SCR key and paste into freeware Irfanview.com app is quick way to share your results.
3. Tips on optimal screenshot sizes can be found here [Guide] Freeware Irfanview Graphics app resizing screen shots (last post has fastest way to batch optimise PNG format screenshots).

Some suggested (not required) apps to include in screenshot:

1. CPU-Z 1.5x
2. Everest Ultimate 5.50.x Released
3. http://i4memory.com/f79/memset-v4-1-...-timings-2868/
4. wPrime Benchmark
5. LinX
6. http://www.virgilioborges.com.br/vir...r_pi_0.99b.zip
7. SuperPi 1.6 Released - Validation is finally working - 1M through to 32M pi tests

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:

• 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

Bootable at 879Mhz 6-6-6-20 1T at 1.66v with CPU VTT 1.3875v

Must be nice.

Keep at it mate - you'll find your way

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.
