Almost same specifics but double price

[MahZi]

Hi
here at my local store KINGSTON - Dual Channel 4GB - 1333-(2x2GB) is 40T (my currency) and CORSAIR - Dual Channel 4GB - 1600-(2x2GB) is 70T
almost double price for being 1600mhz? or just because of the brands? or there are some other reasons I dont know?

I've been using kingston RAMs for year and i've never had problems with them
I also read that there is no much noticeable speed differences between 1333 and 1600mhz

Please help me choose

EDIT: I forgot to tell Im not going to overclock or gaming, just photoshop and watching HD mkv videos
EDIT: both RAMs are CL9 but i'm not sure about timing and actually i'm not very familiar with these terms, are they that importand to make the price much that higher?

The improvemnt from 1600MHZ memory might be in range of a 2-3% maximum. I would not advice to get it since you Wont notice it unless you make huge projects (and i dont think so since then youd have like 24GB ram ).

Better get 8 GB of the cheaper one i think, but lets see what other ppl think .

.. 1600 is the "sweet spot" for a SB CPU, That said, you are correct, there is very little diff between 1333 and 1600. For the price diff go with the 1333. Only get the 1600 if price is NOT more than 10%->15% above the slower RAM.

thanks guys
as I said before it's about 80-90% more expensive
I'm afraid there are more differences than just hz
I'm confused

Here is a good review of speed/timing for SB

Also if for Sandybrige you want 1.5 V RAM, not the 1.65 V.
Yes there are differences in quality. I know your not in US, but Newegg is a good sorce to get an idea if a given memory has problems, or is a good choice - Read the user reviews sometimes take with a grain of salt.

For kingston, reviews look OK: http://www.newegg.com/Product/Product.aspx?Item=N82E16820139075

thank you

well 1600 seems to be a better choice but as i want to buy an H67 mobo, they just go up to 1333
so I think I should take KINGSTON - Dual Channel 8GB - 1333-(2x4GB). right?

 

[RetiredChief]

The 1333 would be a good choice based on price. If you read the previous pages to the anandtech articale the bench marks showed VERY LITTLE performance difference.

 

[MahZi]

so I go with 1333

one more question about voltage
should I be worried to pick 1.5v only?
I mean RAM and mobo can't adjust voltage?

 

[RetiredChief]

Quick check you are asking about DDR3, not DDR2 correct.

If DDR3 then.
Go with the 1.5 V
The bios will normally set the voltage correctly. 1.5V is the default setting for most MB and only needs to be changed if other than 1.5V is needed.

I did not see what MB you have, but most, other than store bought systems (ie dell hp acer), allow for changing the voltage.

 

[itzdanielp]

both the RAM and the MB can adjust voltage, but when you start changing voltages you start changing the performance. You also lose the stability.

Definitely go with the voltage that your MB suggests unless you are going to OC (which you said you aren't)

 

[MahZi]

thank you so much guys
I really appreciate your help

 

[RetiredChief]

"both the RAM and the MB can adjust voltage"
I know you did not mean that the RAM can adjust the voltage, but meant that it can work with different voltage levels as LONG as the max is not exceeded.
On MB adjusting the voltage - If it is a "brand" name store bought computer the manuf may have "locked" the Bios. But agree, DIY MB will allow the voltage to be adjusted and an incorrect level can cause stability problems.

 

[itzdanielp]

er, yeah. That's what I meant ^

*heads off to dig up some more coffee*

 

[RetiredChief]

^ 2nd that, I need a refill (LOL)
