so with ivy bridge 3770K i got i've read online that the memory can go up to 2800mhz.
i cant seem to do it, my memory is refusing to cooperate.

has anyone achieved a successful memory OC with something close to this high?
if so, do tell ur info.


corsair vengeance 8gb (2x4gb) CML8GX3M2A1600C9

Your kidding right? You have 1600mhz memory, your supposed to run it at 1600mhz.

If you had DDR3-2600, you could probably do it. You don't.

If you keep attempting to run it at anything over 1800, it will likely ruin your ram.

With that processor and (I am assuming) a Z77, tests show that speeds over 1800mhz are negligible and near non-existant over 2133mhz. Your better off attempting to lower the timings at 1600mhz

With all CPUs since the Core2Duo and Athlon having integrated memory controllers, the chipset has no impact on raw RAM performance, most differences come from BIOS tweaks between boards.

That said, CPU memory bandwidth has not been a major bottleneck in everyday use with large increases in bandwidth only yielding tiny improvements in benchmarks other than synthetic RAM bandwidth/latency.

I don't think you guys even understand that he was trying to run 1600mhz memory at 2800mhz......lol

^ Very Good catch - LOL.

Not sure about IB, but with SB Ram over the spec (1333) voids the CPU warrenty.
If Intel applies the same "rules" running ram over 1600 May void warrent on IB CPU.

Thanks for that comment. I plan on buying a IB soon (and buying a extended warranty for oc) and thought of over clocking the ram. I will keep that in mind.

Overclocking RAM is not really worth the trouble, overclocking RAM by 50% over the CPU's recommended DRAM interface speed only yields 1-2% improvement in most real-world benchmarks, the difference is only visible in synthetic memory benchmarks.

Okay, thanks for the tip. I did not think it would make a "big" difference but I though it would be something to consider IF it had any improvements in performance.
