Sammy Green 2d+3rd timings

Yeah ive sold two sticks on the MM so im only using two sticks now ie 8gb.
I've got my two sticks stable at 1.55v (1.5375v in bios) at 2133 9-10-10-21-1T
Secondary
5,196,auto12,6,26,6,5,8
I think those secondary ones you gave me were for 16gb though.
Anyway i think i can get more from this 8gb if you can tell me what to do with regards to improving those timings.
Matt what were the highest speeds and timings you could get with 4 x 4gb sticks? Could you get 1866 with 1t?
Also with your 2x4gb sticks at the speeds you got them up to did you notice much of a performance improvement in say bf3 for instance?

Hey Matt/8 Pack so i got the sticks and have them set to the same 2133 timings as LtMatt 9,10,10,21, 1T with the same seconds at 1.55 volts. I've been dialing back the cpu multipler and dialing up the bclk to push the ram in memtest only so far.
I get to 104 with vccio at 1.10 volts and VCCSA at 1.05. cput is at 1.4 volts plus medium LLC. PLL 1.6.
I can get into memtest at 105 bclk but i get a bunch of errors, at 1.575 volts i get a few errors on the memory so i'll try pushing it to 1.6 but is that getting a little to high for 24/7
Also at 105 might it be the IMC that is causing the errors or will i only encounter that once i get into windows and start stress testing.
2 other points - i noticed in you x79 thread 8pack you said that VCCSA and VCCIO should be within in 0.05 volts of each other - is this also true on Z77 - my VCCSA appeared fine at stock - 0.95 volts i think but i brought it up in line with the VCCIO
And
LtMatt i noticed your PLL is quite high at nearly 1.9 volts - did you find it helped you much in your OC - i'm at 1.6 but didn't seem to notice any difference when i took it higher.
Thanks guys
Dave

1.75 is fine so dont worry.
Z77 VCCSA stock is actually 1.1v VCCIO stock 1.05. No the rule does not apply with Z77. For most OC VCCSA can remain at 1.1v just change VCCIO, Play with PLL 1.55-1.65 or try 1.9 all are safe makes no odds.

Well i still got errors at 1.6, so i'm tempted to back down to just 2133 at 1.5 volts. the only thing that niggles is the high refresh cycle time!!! 196!! i take it could just be volts from getting that down as well right.
I'm on sandy bridge so i'm a little wary of taking the volts on the memory too high 24/7. What do we think is ok up to 1.6 - 1.65?

Not this again man!! My sandys all of em!!! VDIMM 1.9+ several years old fine!!!!!!!!!!!!!!!!!!! all of em!!! You can hit 1.65 + on these dimms easy. Get the TRFC down to 124, 104, 96!!
