i7 2700k, Corsair Dominator Platinum OC?

Started my first build, have ordered some basic stuff and have done ALOT of homework but theres some fine details i needed help on.. Assuming i don't Over Clock a i7 2700k, and i am using the the intel DZ77RE-75K Extreme, with Corsair Dominator Platinum 2400MHz 2x8GB. Will the 2400MHz be utilized? The board has support for DDR3 2400+ O.C. Will i have to OC the CPU to get the 2400MHz out of the memory? or will i have to OC the CPU and the RAM together..? If i am only planning on OC just a little will i need the 2400MHz memory or would 1866MHz be better..?
 
you wont really notice a difference between 1866 and 2400, also im not sure if the memory controller on sandybridge will be able to do 2400mhz.
 
Thanks, but i'm trying to understand the OC collaboration between the two, as far as memory being utilized by the CPU without overclocking.. Without planning to OC the CPU will i be better off with maybe a 1600MHz memory..? I might do some overclocking in the future but nothing extreme.
 
Have you already ordered the CPU, if not get a 3770k, assuming you need HT. If you have a k-series CPU you have to oc, it's so easy you can easily get 4.2ghz just by turning up the multiplier.
For the ram, I'd get 1600 or 1866 mhz, ram speed doesn't affect system performace too much
 
I'll ask this way and see if it works...... If i have 24000MHz ram and my i7 2700 is not overclocked...... Will the RAM be running at 2400MHz, or if it's 1866MHz, will it be running at 1866MHz.. I'm not looking for suggestions on what i should buy, it's a question about these specific components..
 
You will have to change some bios settings to get the ram to run at the rated speed, but i dont think the 2700k will be able to run the ram at 2400.
 
So the CPU does not have to be overclocked for this to happen, even if it was a 1866mhz set or a 1600mhz set. i realize the sandybridge will have trouble running 2400mhz.
 
If you do want to go for some needlessly high memory clocks, you'd be better off with Ivy Bridge and Z77, dude. The memory controller on Sandy is a little off, and may have trouble keeping those DIMMs at their rated speed. This was fixed for Ivy.
 
I have heard nasty things about Ivy, heating up after overclocking and im not the most experienced with OC. But with a slight OC if it can manage memory better, and i would see a significant difference to where its worth getting 2400mhz ram, i would definately look into it!

Ivy cpu usually heat up when you push them towards 5ghz, you shoud be able to get 4.2 to 4.5ghz whithout any problems, I wouldn't recommend any more than that anyway if you don't have any experience with oc.
Even if you ask us for the 4th time, 2400mhz ram does NOT get any more necessary
 
dont think youll get 2400 but you will have to set it up in bios manually to try.

Get 2133 stable first but very few will hold 2400 without insane volts and even then you have to win the silicone lottery
 
good to go, well ivy is sounding alot better then thanks guys.. and why do they even make crazy high RAM when nothing can support it..?
 
ivy can support a lot of the higher memory clocks, and as to why its made in the first place, it is for benchmarkers or just people who don't do their homwork and buy crazy fast memory thinking it will make a big diffrence in their system.
 
I believe that the AMD APUs make use of faster memory for their iGPU, but not much else makes use of it. As Tristan says, benchmarkers like it to get as many points as possible, and some video editing/photo manipulation software can also take advantage of the higher speeds. For 95% of the time, though, it has no real use.
 
not all ivy chips can handle high speed memory... it mainly is the duty of
the onboard memory controller. just because it is sandy or ivy doesn't or
shouldn't lock anyone into a speed genre. enthusiasts usually will go high
speed and clock it to their liking. not all ivy can handle 3000 OC. some can't
even clock 2133. again, the silicone lottery has a lot to do with the procedure.
reccomendations on speed is app specific. specialized uses, high data transfer,
scratch disk, complex algorythms and such..so if one has the gumption to
overclock RAM, have at it, but a fail-safe speed is usually 1600/1833. pricing
on RAM is crazy low and speeds are getting faster and most see faster being
bester... in all appz... but usually hard computing is where the speed is going
to be noticed.

now that were on RAM, can anyone explain the difference between two Pairs of 2x4gb one is...

Tested Latency9-9-9-24 and the other is Tested Latency8-8-8-24
SPD Latency9-9-9-24 SPD Latency9-9-9-24

they are both 1600mhz.. ? and all other specs are the same..
