Memory Mhz vs CS

I am considering which set of memory stix to get for my new system.

The primary question I have is, which is better, a faster speed i.e., 1600Mhz vs 1866Mhz or the difference of the CS. The first is 9 and the second is 10/11. Also the second one is 1.5v vs
1.6v?

Whadaya think guys?

Thank!

Jerry

  1. Hi there again : )

    MHz are faster. But look at this.

    RAM speed comparison - We're looking at a less than 2% difference from the fastest to the slowest.

  3. The better to do is to get the faster (MHz) as possible, and the lower latencies as possible.
  4. Thank you jemm! And Thank You Nikorr! I read the article. It seems little is gained going above about 1600Mhz. But you still want low latencies and prefer a 1.5v set. At this point I think I'll go with Mushkin 1866 because it is very little more, and runs at 1.5v vs 1.6v for the 1600. The only down side is the latencies. The 1600Mhz was 9-9-9-24 and the 1866Mhz Mushkin is 10-10-10-27. I hope that is the right choice! I would prefer the lower numbers. Does anyone know a Memory stick that has lower latencies at 1.5v?
  5. Well I found one but boy is it expensive!!

  6. Yes, that's the price to pay for not much gain : )
  7. Oh I think I found the answer. I hate to go to another brand, I really like Mushkin but this meets all my requirements and is a good cost from a good Mfg.

    I'm going to look into this one for now. That one for $500.00 is a choker!

  8. I recommend Corsair the most for stable RAM.

    What is your CPU cooler?
  9. BTW, what is the CPU?
  10. Going to use Thermaltake WATER2.0 Pro.
  11. The CPU will be Intel Core i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo) LGA 1155 77W. I have decided on the Maximus V Extreme. It was a hard decision, but the Ivy Bridge e that will work in a 2011 motherboard is delayed. I don't want to wait for it.

  12. Large air cooler don't like the tall Vengeance RAM.

    This cooler has no problem with fit.
  13. the difference in ram performance is given in the "ammount" of ram available. High speed ram might help if you use your PC for video rendering and stuff (eg you let your PC render some suff for 48 hrs but with high speed ram it might take less with 1 hr ^-, witch honestly ...its not a big deal :)) For a gamer / office user / or multimedia user highspeed ram affects your budget only :).
    So, for a 64bit OS, the jump from 2GB Ram to 4 Gb ram is noticeable, from 4GB to 8GB its less noticeable...and from 4 to 12 .... even less...
  14. Great! I was thinking that heat sink was awful large! I was also hoping the way the Thermaltake covered the CPU left room for them.

    I don't blame u.

    But there is one thing that is out of range for that CPU.

    Its the cooler.

    3770K when OC'd to respectable 4.5GHz needs better cooler.

    Thermaltake CLW0217 Water 2.0 Extreme/All-In-One Liquid Cooling System

    Thank You crisan_tiberiu. So your saying, I don't need the 4x8GB configuration I was planning. Perhaps the 16GB would suffice.

    I appreciate your input!

  17. If u want speed, than this will do. 2x8GB will give u the option for 32GB if needed.

    Are u doing any video editing or 3D or such?

    G.SKILL Trident X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C10D-16GTX

  18. For the Ivy Bridge CPU, the 1.65V is fine,

    it has different IMC (integrated memory controller), than Sandy Bridge thats need 1.5V or less.

  19. Wow that really fills those slots! Lucky I'm picking a watercooler that will fit that Corsair ram.
  20. With this RAM, u can remove the top part so it fits under any cooler : )
  21. Oh that is cool (excuse the pun)!
