What DDDR3 will be the best for O/C with a 2600K?

HI,

I just order via Internet a new Intel Core i7 2600K Quad Core Unlocked Hyperthreading Processor LGA1155 3.4GHZ Sandy Bridge 8MB and I want to overclock it as fast as 4.6 GHz 4-Core; 4.9 GHz 1-Core?

I used the info from this article: http://www.tomshardware.com/reviews/sandy-bridge-overclocking-efficiency,2850-5.html to choose my new components.

But, the Tom's article is using the following G.Skill DDR3 for their overclocking:

G.Skill 2 X 4GB DDR3-2133, F3-17066 CL9D-8GBXLD @ almost 200$ the kit, which I find expensive!

What should be the best RAM (total of 8GB or 16GB) (DDR3-1333 or DDR3-2133) for my new i7 second generation if I want to overclock it at max and not facing a DDR3 bottleneck?

Thank you very much for your help

  1. Whatever you like. The RAM has very little affect on speed. http://www.bit-tech.net/hardware/memory/2011/01/11/the-best-memory-for-sandy-bridge/1
  2. HI,

    I am not concern by the speed but by the possible RAM bottlenecks when I will try to overclock my new CPU at it's max.
  3. As you are multiplier overclocking, you won't have any problems with RAM limiting the clockspeed you can get. (Because you aren't changing the speed at which the RAM is running.)
  4. There are no RAM bottlenecks on the Sandy Bridge processors. Even if you overclocked to 6.0GHz by multiplier only (which isn't even possible with current Sandy Bridge processors), a dual-channel DDR3-1333 kit could still be used. The memory controller is that good.

    For most people, an 8GB (2x4GB) DDR3-1600 CL9 kit offers great performance and won't break the bank.
  5. ... then, do you have a prefered RAM model and speed ?

    Thank you all for your help.

  6. Kingston HyperX ram is really good
  7. You have the right manufacturer. Just get one of G.Skill's lower-speed kits. The F3-12800CL9D-8GBXL is a good one at a good price.

    I have two G.Skill Ripjaws X DDR3-1600 CL9 kits in my Sandy Bridge system -- one 2x4GB kit and one 2x2GB kit for a total of 12GB. I don't really need 12GB but it was on sale that week from NewEgg, so I figured why not...

    6GHz SB are possible:

    @OP: This are very good and overclock without problems: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231353&Tpk=PI%201600
  9. HI,

    I was also told it will be easier for the motherboard controler's to overclock a set of 2 X 4GB DDR3-1600 then a set of 4 X 2GB DDR-1600.

    Is-it true ?

    Thanks

    Yeah, that's totally true. Plus, with 2x4GB you have the possibility to add another 2x4GB kit in future, while with 4x2GB you can't.

    I meant by multiplier only. As BCLK overclock on Sandy Bridge isn't very successful, I usually forget that some people still do it. The post has been edited to reflect my meaning.
  12. HI :hello:

    From all your good comments, I decide to choose between the followings:

    1) G.SKILL Ripjaws X Series 8GB (2 x 4GB), 1.5V, 9-9-9-24, 240-Pin SDRAM DDR3-1600 (PC3 12800) Model F3-12800CL9D-8GBXL @ 96.99$ per set.

    OR

    2) G.SKILL Ripjaws X Series 8GB (2 x 4GB), 1.5V, 9-10-9-28, 240-Pin SDRAM DDR3-1866 (PC3 14900) Model F3-14900CL9D-8GBXL @ 126.49$ per set.

    Those prices are so good that I will buy 2 set of 8GB for a total of 16GB and I think I will take the option 2.

    Thank you very much for your help :sol:

  13. It's hard to beat low cas DDR3 1600 with these chips. I have this with my 2600K. You can also find some cas 6 if you look around.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16820231431
  14. A DDR3-1600 (2 X 4GB) with a CAS 7 @ less then 150$... this is a good price.

    Thank you,

    JF
  15. Sandy defaults to 1333 cas 9-9-9-24. Benchmarking it there with WEI it got a 7.6. After I enabled XMP and ran the memory at 1600 cas 7-8-7-24 it gets a WEI of 7.8. ( Windows experience Index up to 7.9 top )
  16. You want a 1.5v kit for 1155 motherboard. That's what is recommended.

    I had the same questions you did when purchasing... here's what you want...

    http://www.newegg.com/Product/Product.aspx?Item=N82E16820233144&cm_re=corsair_8gb_ddr3_1600-_-20-233-144-_-Product

    Corsair has a much lower failure rate than G.Skill.
  17. High CL for 1600, take a look of newegg and Google and you can find RAM with the same CL but running at 2000MHz or even more.

    That is actually a good price. However, it's not worth the extra expense over regular CL9 DDR3-1600 RAM. The performance difference is only a couple of percent, and you will not notice that while doing normal tasks or gaming. Save the money and spend it on something that will make a real noticeable difference like an SSD or a better graphics card.

  20. HI,

    I will finally buy a CL9 DDR-1600.

    Thank you very much for all your help.
