I'm building a i7 rig. Is using triple channel memory important?

I am ordering this today: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277&cm_re=G.SKILL_Ripjaws_Series-_-20-231-277-_-Product

Should I order another set and use all 4 sticks? Order another set, use 3 sticks and sell the 4th one? Or just use 2 sticks in total?

I mainly use my computer for gaming. I don't know how much memory and what combination is recommended for a windows 7 gaming rig?

More about building triple channel memory important
  1. Ahh, more than likely (95%) that DDR will not work. What MOBO is the DDR3 for {Model}?

    You either want Certified {via MOBO} or Tested {via RAM Mfg}.
  2. Using A EVGA X58. According to the EVGA website this ram will work.
  3. Actually EVGA doesn't list an exact match to this model number. It does show the 8gb set 2x4 as being compatiable. I imagine if the 4x2 set is the 2x2 set would be as well.
  4. "Actually" = oops! There several EVGA X58 MOBO's - which is yours? {e.g. EVGA X58 SLI | 132-BL-E758-A1}

    Instead use G.SKILL Configuration - http://gskill.com/configurator.php

    The P/N MUST be EXACT per your "EVGA X58 MOBO."
  5. EVGA X58 SLI. I was only thinking about getting this ram because of a Newegg combo deal with the case I want. I guess I will hold off on the ram for now.

    Should I look for a triple channel kit instead? If so I imagine a 6gb 2x3 set would be plenty for a mainly gaming rig.
  6. ^ Still too vague Chief {EVGA X58 SLI has 6 flavors}. In general the X58 works best with Tri-Channel DDR3 {3 X 2GB - for WIN 7 64-bit OS}; Keep in mind Windows XP/Vista/7 32-bit is capped at 4GB - limit of 2^32 addressing. Also, Hexa-Channel 6 X 2 GB is somewhat less efficient and somewhat slower. Windows 32-bit 2GB minimum/4GB Maximum and Windows 64-bit 6GB minimum - to perform best.

    Example:
    G.SKILL - http://gskill.com/configurator2.php?pid=2&model=72

    Hope that answers your questions & Good Luck Building!
  7. Sorry for being vague. You had posted in the thread I started about the mobo I am going to use. http://www.tomshardware.com/forum/280048-30-thinking-building-setup-mobo-recommend

    Here is the model number of the mobo I ordered: 132-BL-E758-RX

    I ordered a "B" stock from EVGA for 90 bucks. I figured it was worth a shot for that price. I plan on using Windows 7 64 bit.

    Then 3 X 2GB is the ideal set-up is ideal for Tri-Channel + Windows 7 x64. My preference is {Corsair, Mushkin, G.SKILL, Kingston}

  9. Thank you very much jaquith!

    I will keep an eye out for a good deal on a 6gb 2x3 set that EVGA says is compatiable.
  10. ^ you mean 3 X 2GB.
  11. Yes. 3 sticks of 2gb for triple channel memory.
  12. I now know I want a triple channel kit that is compatiable with my mobo according to the EVGA website. My next question is what speed should I get? I assume getting DDR3 2000 would allow me to overclock the 930/950 easier since their multipliers are locked. How important are the timings? This is the set I am looking at right now: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227570&Tpk=OCZ%20OCZ3P2000LV6GK%202GB
  13. DDR3 2000 is only "needed" if you're really pushing OC and need the extra FSB ~ pushing past 4.4+ GHz. If you're pushing a 4.4~4.6GHz+ OC then you'll need to waterblock everything {CPU, GPUs, & ~ MOBO}. So add another +$600-$1,200 to the budget and look at http://www.koolance.com/default.php .

    Otherwise, 1600 or 1800Mhz is a solid choice.
  14. The price of the DDR3 2000 is very close to the prices of the compatiable DDR3 1600 sets I've found. I was figuring if it is only a few dollars more for the 2000 it couldn't hurt.

    I don't plan on overclocking that high. If I get anywhere near 4 ghz on air I'll be happy. I don't know exactly what type of memory overclock that will take. I haven't even started to research overclocking an I7 930/950 setup yet. I am sure I'll be able to figure it out though. My E6600 has been overclocked to 3.2 since the day I built it 3 years ago and it is still 100% stable. I hope to get the same reliabiltiy with the I7 build.
  15. The problem with 2000 MHz is the high CAS speed {slower}. For ~ 4GHz use 1600 or maybe 1800 MHz. The ideal situation is low CAS + High Speed = expensive. In other words, 1600 MHz with CAS 6 is much better than 1800 MHz CAS 9.
  16. I understand that lower cas is faster. I imagine memory that is rated for 2000mhz at 9 9 9 24 would probably be able to run at a lower cas at 1600mhz.

    Anyway, I need to order ram within the next few days. Finding a good deal on a set that is compatiable according to EVGAs site is not easy. Hopefully I will be able to find something soon. If anyone here has any recommendations for me I would appreciate it. The motherboard I am using is the EVGA X58 SLI.

    I am buying the processor today or tomorrow. I am still trying to decide between the 930 and 950. The 950 is $32.00 more than the 930. Lol. I am such a cheapskate!

    Yes, that is correct.

    i7 950 $299 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819115211
    i7 930 $285 - http://www.newegg.com/Product/Product.aspx?Item=N82E16819115225
    =========
    Diff = $14
  18. Microcenter has the i7 930 for $199.99 and the 950 for $229.99. In store pickup only though. There is one about an hour drive from my work. At those prices it is worth the drive.
  19. ^ Yeah, I seem to recall that {was that your post before?}. Then no, stick with i7 930 - just check the warranty which should be 3-years {typically Box version}. OEM is typically 1-year warranty.
  20. I will check the warranty. It is the retail box version so it should be three years. So you think I should save the $31.87 incl tax and get the 930?

    I've been reading some reviews on the CORSAIR DOMINATOR ram you linked me to. It is the highest rated 3x2gb ram I have found yet. It is about $20-30 more than other kits but it appears to be worth it.
  21. I've used that DDR on 4GHz OC'ing. Regarding the $31.87 - personally I would get the i7 950 but that's me and my idea of budget. The Core Ratio is +2 which is easier with BCLK {133.33 X 2 = 0.27 GHz ; 160 X 2 = 0.32 GHz} - so to get the same speed I just need to raise the BCLK a tiny bit ~ +heat.

    Now if it were a choice between the i7980X verses a large SSD - the SSD wins. I can OC a i7 930 to make the difference negligible.

    i7 930 - http://ark.intel.com/Product.aspx?id=41447 Core Ratio 21
    i7 950 - http://ark.intel.com/Product.aspx?id=37150 Core Ratio 23
  22. I ordered the 950! I am going to pick it up tomorrow. I still haven't ordered the ram yet though. I have a hard time paying almost $200 for 6gb of ram. I was hoping the Dominator ram you linked me to would go down in price but instead it went up $10! The ram is the last thing I need to get this new rig up and running. Maybe it will go on sale over the weeked! Lol3

    The mobo won't be in until early next week so I have a few days to wait for a good deal on a compatiable 3x2gb set or ram!
  23. Whatever you decide, get 3X2GB of minimum 1333 or 1600 for OC. You, have the list and I "get" $. :(
  24. I ordered this today: http://www.newegg.com/Product/Product.aspx?Item=N82E16820104116&Tpk=KHX1600C8D3K3%2f6GX%202GB

    It is on the EVGA recommended list, was much cheaper than the Corsair, I've had good luck in the past with Kingston Hyper X, and it came with a free cooling fan today. Hopefully it works well. According to the few reviews on Newegg it appears people with EVGA SLI boards have had good luck with it.

    I picked up the 950 today. Hopefully the mobo and ram will be in by mid next week. I will post my results once I get it up and running.
  25. RAM looks good with good CAS 8-8-8-24 - very good choice!

    This all sounds great! You'll enjoy!
