Help choosing the right memory.

[radaevia]

Hello, my computer is already being built as i write this message, im only missing memory sticks which i didnt pick yet.
This is the computer (mainly for gaming):
1. Gigabyte Z77X-D3H
2. Noctua NH-D14
3. i5 3570K

i think the noctua d14 requires me for a Low profile sticks ...

i want a total 16gb of ram and the memory should be good quality, fast and good with OC.

These are my options according to the store current stock:
2x8GB G.Skill Ares Dual Channel CL9-9-9
2x8GB G.Skill Ripjaws-X Dual Channel CL9-9-9-24
4x4GB G.Skill SNIPER Edition Dual Channel CL9-9-9-24 (Low Voltage)
4x4GB Corsair Vengeance Blue LP Edition CL9-9-9-24\
and some other kingstone sticks

i really prefer using 2 sticks of 8GB over 4 sticks of 4GB because of the OC.

G.skill ares is a good choice?

 

[ubercake]

Yeah. 2x8 for sure for the OC. I would definitely choose the Ares based on the lower profile, since you're getting the NH-D14.

 

[radaevia]

So the g.skill Ares is my choice? its 1333mhz and 1.5V, it doesnt matter right?

 

[ubercake]

The difference between 1333 and even 2133 is only noticeable in synthetic benchmarks. You might buy a frame/second with the faster RAM, so I wouldn't rely on your RAM to do too much for you with regard to gaming. Of course the higher speed RAM will require little to no overclock, but an OC on the RAM, in my opinion, is not even worth the risk for what you get out of it. It's either high risk or low risk with the same outcome: little return.

The Ivy Bridge CPUs are intended for use with 1600MHz memory.

As far as OCing memory goes, you will only get 1-2% performance improvement in real-world benchmarks between 1333MHz and 2133MHz so very-high-performance RAM is one of the least cost-effective investments you can possibly make, not worth spending extra on it unless you have already maxed-out everything else. I would simply go with the lowest latency 1600MHz DIMMs I feel comfortable paying for.

 

[ubercake]

Intel spec lists 1333 or 1600 speed memory for the ivy bridge processors:

http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-(6M-Cache-up-to-3_80-GHz)?wapkw=i5+3570k

The 1333 has a lower latency. The 1600 offers a higher speed. In the end, you won't notice the difference.

If you want to OC the RAM regardless of what we've said, they offer an 1866 Ares kit at a subtantial $ amount more.

Any verdict ? what should i pick from what i listed?

 

[radaevia]

ubercake, i can pick only from what i listed, the store doesnt have any 1866 ares models?

will the normal 1333 ares will be good choice?

I would say Ares (or any other model from a reputable manufacturer) 1600 10-10-10.

9 cycles / 1333 = 6.75ns latency
10 cycles / 1600 = 6.25ns latency

So the "higher latency" (10 cycles) 1600MHz RAM actually has 0.5ns lower latency on top of 20% faster burst rate, no reason to go with the 1333MHz version.

What's the price difference?

 

[ubercake]

Go 1600 if it's in your budget.

 

[radaevia]

as i said guys i can only get one of the RAM i mentioned at the start ... the 2X8GB are both 1333.

what can i do...

 

[InvalidError]

what can i do...

You can get 1333 too, it does not matter all that much. As we said before, there is only 1-2% performance difference between 1333 and 2133 in most real-world applications, not worth losing sleep over it if you cannot get the 'ideal' RAM for whatever reason.

 

[radaevia]

Ok getting the Ares 2X8GB then...

10x alot for all the help

 

[nikorr]

Yes, the Ares is good too.

I would go with 4x4GB Corsair Vengeance Blue LP Edition, but u are fine.

 

[radaevia]

i would too but seems like using all of the 4 RAM slots on the boards is not good for OC.

am i right here?

 

[nikorr]

Nope.

What do u want to OC anyway?

i would too but seems like using all of the 4 RAM slots on the boards is not good for OC.

It makes no difference if you overclock a K-chip since you are going to OC the CPU by changing the CPU multiplier while leaving the RAM at stock clock.

The main disadvantage to quad kits is you have no room to add more RAM later without throwing out some DIMMs.

 

[nikorr]

2 sticks are "better",

because the chance that 1 will go bad is slimmer, than with 4 sticks : )

U wouldhave to be unlucky to get bad RAM stick.

 

[radaevia]

cpu and gpu? im dont know much about OC but i do know i want to leave that window opened for me in the future when the computer will be "old".

 

[radaevia]

Ok, thanks all!
I took some time reading and narrowed my choices based on your suggestions and my store's stock to 3 final options, first 2 are 1600 and the third option is 1333:
1. 4x4GB G.Skill Ares Quad Channel 1600MHZ
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231547
2. 4x4GB Corsair Vengeance Blue LP Edition 1600 MHZ
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820233196
3. 2x8GB G.Skill Ares Dual Channel 1333MHZ http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231556

Added links to the exact models.

What should i pick?

It all boils down to whether the 1-2% performance improvement with 1600MHz kit is worth more to you than the lower total power and possibility to add more RAM later with 2x8GB kit.

 

[radaevia]

I really dont see any point getting more then 16GB today, even 8GB is overkill to most or all the games around.

I really wanna make my pick based on a more reliable, stable and quality ram.

And again, thanks!
