ivy bridge: low speed/low cas vs high speed/high cas ddr3 ram kits???

[STiTRON]

I'm making a new build, I've been trying to get a definitive answer on this for a while.

I'm trying to decide between a 16gb 1600mhz cas 7, vs the corsair dominator platinum 2133 cas 9 kits. I have also read that using higher density/speed ram kits can limit your maximum cpu overclock. Is that a common problem with ivy bridge?

I will be using it with a 3770k and the asus maximums v extreme.

I know the gains will be minimal, I'm just looking for the best outright performance.

Please don't respond with "use google" or "read other post", this is a forum for help. I've looked at a lot of review, charts, and other information. I'm just wanting some other opinions!!!


Any help will be greatly appreciated.

Never had any trouble oc`ing my 3770k with 2400mhz rams on M5G.Have tried G.Skill TridentX 2400mhz c10 8gb kit and TeamGroup Xtreem LV 2400mhz c9 8gb kit.
The IMC on ivy-bridge is very good.Only limitations is the mobo you use,but shouldnt be a problem on the M5E.

I've personally gone on the look out for good timings whenever buying memory, purely from a matter of principle and how the memory timings may need to be inflated the more I overclock.

The study is pretty correct, the limited bits of it I just read, in so much as these days, the speed of memory is that-quick, that thinking c9/10/11, strictly speaking doesn't really matter. Benchmarking, the better setup wins out in the majority, often by numbers that don't mean anything. When you're rending or smashing aliens on your fps, it means even less. Cpu overclocks over stock with an i5 means about the same. Good number on paper, meaning nothing in-game.

.. still, I'll always look for the C9 2000 memory .. knowing I'd probably have to make it C10 to oc higher, rather than C8/9 1600 and have to do the same just to get around 2000 with it.

Bah.

I've recently researched the exact same thing in combination with an ivy bridge processor.

The result ended up being that the timing weight much less than the speeds. This used to be important when the timings could be really low but not so much from c9-c12. The rest used a high speed memory and clocking them a bit lower for tighter timings and overclocking them with worse timings. It ended up having almost no speed increase with tighter timing but it did increase a lot with higher clocked memory.

A very interesting and informative article STiTRON , thanks for the link.

i and other believe the ivey/sandy are speed demons and to anchor the CPU with
a narly overclock and slow memory speed is counter-productive. now for appz
other than gaming the speed is greater (photoshop, premier, after effects...)
but like you asked.. you want the edge on performance.. 2133+ is bestess.
the platies are "nads" for the look, but pricewise.. there is better.. but my vanity
has to be part of the overall as well...

Basically you should get a cas 9 2133mhz kit for ivy bridge. Anything higher has diminishing returns for money and performance

I have seen some sizable increases in performance in certain applications between 2133 and 2400 MHz. I think these are as good as it gets for 2400 MHz memory.

Yar, IB loves raw bandwidth. Latency doesnt mean as much as it used to with the MHZ being so blazingly fast these days. 2133 is at that price/performance balance peak.
