  1. Whats your hardware?

    Yes, in most cases, 99%.
  2. p8z67-v, i5 2500k, gtx570.. Soon to be SLi, looking to upgrade from 8gb vengeance blue 1.5v to Dominator 16GB DDR3 1866MHz C9 Memory Kit.. Quad channel.. But ive only dual channel board :/.. what you reckon? Sail! or Fail! ..

    Yes or No?
  3. I have the same board with 4x4GB : )

    Quad channel depends on the board and yours is only dual, so it will work just fine.
  4. Awesome Nikorr MY MAN!!! You and me.. BEST FRIENDS FOR EVER!!!
  5. Duh, high frequency RAM is the 1% as posted above. Two Kits will rarely operate as the same Frequency + CAS Timings as they do individually. So the e.g. DDR3-1866 'might' together only run at CAS 10 and 'might' be okay with CAS 9. It's a trial by post failure and maybe a DRAM Voltage + VCCIO increase.

    If you look at places like NewEgg and look compare high frequency kits you'll notice a lower CAS with the (2) sticks vs (4) sticks -- this is an IMC issue aka limitation.
  6. For the record.. what RAM do you run? (frequency and latency?)
  7. On what PC of mine? On my gaming it's running CMT12GX3M3A2000C9 http://www.newegg.com/Product/Product.aspx?Item=N82E16820145329 which is DDR3-2000 9-11-9-27 but it's running 2240 MHz and 9-9-9-24 @ 1.70v and QPI @ 1.37v.
  8. Thats awesome! BUT back to my question.. Will the RAM ive chosen run on my system? In purely a Dual Channel setting? regardless of timings or frequency? Im under the assumption, quad channel ram, is 2 of, dual channel rams set up for a higher bandwidth through a different CPU socket?

    Ill OC later, but first id love to know (being a noob) if my guess is true. Or will it just not work at all with either my m/b or CPU?

  10. The Will quad channel memory work in a dual channel motherboard has a lot of inaccuracies. For example XMP, if you take (2) kits and try XMP chances are you're going to get a BSOD or Post Failure. The CMP16GX3M4X1866C9 kit was specifically designed for P55/LGA 1156 so the JEDEC is optimized for those systems. Next, both Frequencies and CAS Timings are indeed tailored to 2X__GB and 4X__GB kits.

    If you have an LGA 1155 / SB then I'd recommend the Corsair Vengeance and anything faster than DDR3-1600 CAS 8/9 will offer little to no benefits; see -> http://www.bit-tech.net/hardware/memory/2011/01/11/the-best-memory-for-sandy-bridge/1

    Further, without knowing what CPU or MOBO it's impossible to make any recommendation.
  11. Jaquith OK! What about a lower frequency then? I want that RAM because its dirt cheap at my local hardware store!! I dont even know if it comes with dhx pro..

    Will it work? benefits or not?
    If it will -is it a ballache? if it wont -is it because of the frequency?

    Should i just chose a lower frequency quad kit?

  12. imagine you had my system, and you had 300 bucks to spend on new memory.. You ideally wanted 16gig for future proofing.. What would you buy knowing the system ive got?
  13. Corsair CMD12GX3M6A1600C8 6 x 2GB DDR3 SDRAM Dominator Memory alternatively, i could buy Corsair CMD12GX3M6A1600C8 6 x 2GB DDR3 SDRAM Dominator Memory and sell 2 sticks on ebay...
    could i use 4 sticks of this in dual channel?

    If you want someone to tell you only what you want to hear then I'm the wrong guy ;)

    Here's what I recommend, and with DDR3-1600 you'll have the least number of problems -> http://www.newegg.com/Product/Productcompare.aspx?Submit=ENE&N=100007611%20600006073&IsNodeId=1&page=2&bop=And&CompareItemList=147%7C20-233-143%5E20-233-143-TS%2C20-145-347%5E20-145-347-TS%2C20-231-456%5E20-231-456-TS%2C20-231-429%5E20-231-429-TS

    I can't help 'cheap' -- maybe they're cheap because folks want LGA 1155 sets...
  15. If you have 4 sticks, and your motherboard has 4 slots, it will work.
