8GB G.Skill DDR3 PC3-12800 1600MHz RipjawsX Series for Intel Sandy Bridge Platform (8-8-8-24) Dual Channel Memory kit (http://www.memoryc.com/computermemory/ddr3/8gbgskillddr3pc3128001600mhzripjawsxseriesforsandy bridge88824dualchannelkit.html)

For 2133mhz..actually 2143 mhz at present running at 1.53v

What are the official/semi official timings for these? with the following uefi options:

Hi Kick,

For the official timing, please check out our 2133Mhz products: G.SKILL- World leading DDR3 computer memory and SSD manufacturer -Products (http://www.gskill.com/products.php?page_sel=2&c1=1&c2=3&c3=68)

But your timing is better then the official settings, you may try to lower the first one(tCL) to 9 by same voltage, if not work, slightly raising the DRAM voltage to 1.55v for another try.
Hope you can get the great number and share with us!

That looks dang good to me kick for 2133MHz try ^^^^ and see wot pops

Thx guys,
I suppose I need to give a bit more information.

At 100 base clock 2133mhz 9-11-10-(28-34) with the other timings on auto all post and boot at 1.62,1.635 and 1.65 v but not below that.
Even 9-10-10 24 posts and boots at 1.65v but no amount of twiddling around with vtt ,or even lowering the base clock by 1 to 99 seems to get the sticks long term stable.
At that point the benchable performance is already below 10-11-10-28 at 100.5 bclk.Even at 100 baseclock on either 9 or 10 is around .5gb/s like 27.6 vs 28.2.
Latency there isnt much in it either.
Im not complaining..:) ,it clocks as well as Id hoped, but Im not going to leave it at 1.65v 24/7 cos its not stable at least on my settings with 9 cas.

10-11-10-28 at 1.53v(it seems ok at 1.5v also) at 2143 or 100.5 baseclock with 4.82 cpu is long term stable at least in my testing/usual applications and games.
Ive tightened up some of the secondary timings with suggestions from site members but this memory like my gskill 1333mhz 9-9-9-24 has been tested onthe ext6 p67.whether by Asrock or Gskill im not sure.

Either way Gskill must have done some testing on the sticks ,I was wondering what the best /usual secondary timings on those are for running at 2133mhz are or perhaps the usual secondary settings for gskill 2x4GB DDR3 sticks sold as 2133 17000 10-11-10-28 memory..there seem to be quite a few of them?

Of course if "Jim"or anyone in the Gskill testing/binning lab discovered that some samples of my sticks will run at 9-9-9-24 at 2133,and they just need to be undervolted to 1.45v or something equally unlikely!:smilies13, feel free to let me know.
