    My other sticks work well with the voltage setting. Any less on my Gskills and I lose performance then stability.


    STrange thing is that MSI has the VCCIO default to 1.31v on this particular MB and MSI says it is perfectly safe at this setting. To be safe I went as low as I could go.

    I am not at my RIG right now so can't tweak right now. But I think my problem was the TRFC timing setting. I will adjust as you recommended when i have time and get back to you.

    Every other board maker, and Intel themselves, say 1.2 V MAX. That's the first I've ever heard that higher is OK.


    Yeah, do keep us informed of how things go. I mean, it's more than possible you got a bum set, but i did find that those two secondary timings were crucial to stability.

    Yeah fwiw even my older MGH-E Hypers need a relatively super-loose tRFC to hit the high clocks on tight timings (8 and lower).

    I would agree with you but each time i look at there site or get a email of asking what the D is i get different responses.

    Like really do they know as the last time i emailed them they told me it was double sided.

    Yeah, i know they can be confusing.:laugh: Should ask them the server stuff and laptop stuff get's a "D" as well.:roll: Typical email support. I know I've got it right.;)

    I've tried a number of different timings and voltages under 1.575v and I'm unable to get the ram to boot at 2133mhz with my 2500k at 5ghz.

    My gskill ram scales super low voltage at same speeds at the Sammy's and the Gskill have higher stability when over clocking the ram and my system.

    Unless i find a magic setting for the Sammy's they are going back to the store soon. I don't see the point of keeping them over my Gskill.

    What kind of timings do you have and what is your VTT voltage set to? You can't expect stock timings to work at 2133mhz, that is a little unrealistic imho.

    Or you could hook up one of our non-US homies.

    I can see how the Sammys with the low profile and great low voltage/high frequency performance is desired.


    I think I imght have a slightly low performing set of Sammys though. I wouldn't want to sell them to anyone because I fear the buyer might not be happy with them.

    My experience is that not all cpus/gpus/ram perform the same. Manufacturers design them to run at a certain speed but over clocking isn't a guarantee.

    I have tried all the working settings that I have seen on other systems and I have made timing/voltage adjustments as recommended by CADAVECA.

    I'm running a 2500k at 5GHZ for my testing. 2500k doesn't have as strong as IMC as the S2011 cpu in the TPU review that achieved a 2400mhz over clock on them.

    My experience is that system voltage settings vary from one to another and tweaking is how you find the system sweet spots. I found some sweet spots for my system with Gskill ram and I have made ram timing adjustments for the Sammys and have had some decent low voltage/high performance results with my system. The Sammys that I have are not stable at high CPU speeds. My whole system is unstable at higher cpu speeds with the Sammy's.

    The Sammy's are a great set of ram but my more expensive Gskill's offer more over clock ability and perform better in my system.

    Plenty of 1155 rigs have been able to do 2133+. Once again, we're willing to help you out with your over-clock if you can tell us what kinds of timings and voltages you have. I'm not saying that the G.Skill isn't faster, all I'm saying is that with the proper tweaking the Samsung chips should be able to hit 2133.

    Wellll...if you were to sell them here that's generally not so much of a concern.

    Had some time to play so I broke out the Sammy again.

    This time I found a sweet spot for 1870mhz 1T-9-9-9-27 1.56v with 2500k@5ghz.

    I'm thinking about keeping them again. :D

    I might get add a 2x2GB set of Sammy's for a total of 12GB and use the 2x2GB kit for crazy OC benches. :toast:



    Next test is 5GHZ with the ram at 2133mhz.

    I'm stuck at 5GHZ. It wont boot at 2133mhz@5GHZ with the Sammys.

    Anyone else taken the Sammys at 2133mhz@5GHZ with Sandy Bridge CPU?

    Hey Dave how about a comprehensive ddr3 overclocking guide on different platforms for techpowerup. Im sure like myself alot of fellow tpuers were not aware of how key some timings are to stability:)

    nice one sonda , looks like you are getting somewhere now :)

    Possible in the future, for sure. I'd very much like to do so, actually, and thta was part of my plan wit hememroy reviews. I have a couple of other reviews to do first that may prove to be excellent reference material for that.

    That could very well be the issue. As teh CPU speed increases, so does bandwidth, so it's morethan possible you are right and the sticks won't support such a high bandwdith.
