It can. ECO at 1333 is 9-9-9-24@1.5v, but @ 1600 it is 7-8-7-24@1.35v. This at stock settings.

yes i just saw the attached pic ,
but can u xplain how that is ?

that same RAM can run 1600 at 1.35 V ?
and even at better timmings from 9-9-9-24 to 7-8-7-24

i can understand if a RAM is of 1600 at 1.35V , 7-8-7-24 default can be overclocked to 1866 at 1.5 V , 9-9-9-27

Ok.
The default at 1333 is 9-9-9-24 at 1.5v.
The default at 1600 is 7-8-7-24 at 1.35v.
It looks weird, but true.
It is the memory controller on them.
I can easily hit 1666 at 6-8-6-20-24-1T on them.

No, he was just using the ECOs as an example that there is better RAM out there

Yes. Plus etfreind has saying that he couldn't get better timing with an increase of speed. I was showing him that it is possible. ECO is still an example that it is possible.
But I still think that the OP can hit 1600 9-9-9-24 with a little more voltage. If I'm correct it uses the same MC as the 1600 9-9-9-24. If I'm not correct please correct me XD_1771 AKA "THE MEMORY GOD".

Nope. I left it at stock voltage 1.5v. How much voltage do I have to add to go 1600? How do you know if too much or too little voltage is applied? And how do I change my timings? Do I just lower my 9s to 8s?

Sorry if this sounds dumb, I have little understanding about overclocking ram. If you can forward me to some good articles on overclocking ddr3 ram that would be great.

It's unfortunate because I should of bought 4GB (2x2gb at 1600 and low timings for cheaper than I bought these -_-). I made this computer for gaming. I thought 8GB would be future proof because I won't put together another build for at least 3-5 years. It sucks that my 8GB sticks are hard to overclock. I knew I should of joined this forum before I bought my computer parts frown.gif

Ok. The voltage is a little hard to pin point, because not all memory sticks are made equal. At best I will say at 1333 is timing is 8-9-8-24. The only way to know on the voltage is to slowly increase the voltage and stress test it.
Now at 1600 9-9-9-24 I would say between 1.6-1.7v.

It may use somewhat lower binning i.e. earlier 4GB DIMM ICs that really didn't clock that well but were enough for generic spec memory.
Likelihood I think is that it'll max out at around 1450Mhz CL9 or 1333Mhz CL8 and not further
But the only way to know is to actually try

^^^^^ I would say going with what "The Memory God" says. He is alot better with memory then me.
