Intel P67 only uses DDR3-1066 or DDR3-1333?

Why do the Intel branded boards only say DDR3-1066 and DDR3-1333 support? Do they not work with DDR3-1600? Is it that big a difference if I want to overclock?

  1. Depending on how much you want to OC, you can always get the memory multiplier down as you raise the FSB, if it's a reasonable, healthy overclock it won't make too much difference.

    And no those boards cannot run at 1600.
  2. Intel doesn't use FSB anymore...
  3. Yea I had forgot that, you can raise the multi now which is alot better, and almost won't limit it at all as you can just keep pumping the volts on the cpu without touching other values, so the memory speed is even less relevant
  4. So the question remains, why do the Intel boards not support DDR3-1600, when ALL the other P67 boards support up to DDR3-2000 and higher?

    Can I still overclock to 4ghz+ with DDR3-1333?
  5. This one says to support up to 1600:

    And yes you should still be able to OC to 4+ghz as the current SBs have an unlocked multiplier, each multiplier bump increases it by 100mhz, these are said to hit 4.4 ghz on stock volts and cooler:

    "Since we’re relying on multiplier adjustment alone for overclocking, your motherboard and memory actually matter less for overclocking with Sandy Bridge than they did with P55. On both P67 and H67, memory ratios are fully unlocked so you can independently set memory speed and CPU speed. Even the GPU ratios are fully unlocked on all platforms and fully independent from everything else."

    For Anandtech:

    And why do you want an intel motherboard BTW? they're expensiver, have less features, and won't make your system more stable than other mobos.
  6. Cool, thanks for the info.

    Actually the Intel boards are the cheapest p67's on newegg. The one you listed is their high end board.
  7. I still don't understand why only the Intel boards are limited to 1333....
  8. AND you're using a maximus IV formula. See the difference?

    Whats your point? The majority of P67 mobo's allow you to select between 1333, 1600, 1866, 2133

    Were not talking about the majority. Were talking about two specific Intel branded motherboards.

    THE QUESTION IS WHY ARE THEY LIMITED TO 1066/1333? If nobody can answer the question then dont try. I could care less if your running your ram at 3000mhz.
  10. All I can find on Intels sight is "Serial Protect Dependency" memory only. Whatever that is. Tried to get on live chat with no results.
  11. Yeah me too. I wish someone could shed some light on the matter. It's the same revision p67 chip, obviously because they all just came out. It should support the same memory as the other makers boards.

    Yes, assuming your bios has an OC setup in it.

    While other boards do show higher speed RAM as usable in their boards, mine (an ASUS P8P67 Pro) also states that anything over 1600Mhz will be run as 1600Mhz. It states this is a characteristic of the CPU. Therefore, IMO, it is pointless to use mega speed RAM. Intel claims the CPU is designed for up to 1333Mhz. There is nothing much wrong with this fact although many posters on this site seem to only care about speed and not stability. You would be hard pressed to see the difference in real world actual use, except in test programs.

    Read this review carefully and you'll see what I mean:
  13. Yea, memory scaling at anything over 1600 isn't much impressive, just not worth the price difference, A 1600 low latency ( cas 6-7) kit will benefict games more than a 2133 cas 10 kit.
  14. So basically it's a gimmick to make a company's board look more impressive and the reason Intel doesn't market it is why?

    I mean the high end Intel boards say they support over 1333, but the low end boards do not.
  15. By the DDR standarts the fastest official ddr3 speed is 1333mhz, if you look at other motherboard specs they list anything from 1600 and above as OC, even though there are 2400+ modules, it's like getting a factory OCed video card.

    It doesn't make alot of difference anyways, just spend a few dollars more and go for a different brand if you want to use 1600, only Intel knows why they decided not to include 1600 support.
  16. Yeah well I wasn't planning on buying the Intel board, just wanted to know the reasons behind the 1066/1333 limit.
  17. Because the SB CPU has a SPEC 'Supported Memory" which is limited to 1333 MHz, and Intel's BOXDP67BG also ADDS 1600 MHz 'supported' speed. Intel is not going to out/over spec their own CPUs. Oddly, many Intel P67 MOBO won't support the unlocked 'K' CPUs either - i.e. won't allow for OC'ing of their own unlocked CPU.

    That's a corporate decision, and my first assumption is an Anti-Trust policy. So I severely doubt that Intel will be publishing something like that openly.

    1333...vs...2133 MHz RAM with SB read the entire article; in short RAM > 1333 MHz will see only a modest gain. Next, you need to factor-in errors and you end up scratching you head -- is 1333 MHz $50 worth the 2133 $150 with SB??!!
  18. I don't believe that about the Intel boards. They have all the processor and memory tuning features you need, besides, with the K's you just raise the mulitplier, that's it.
  19. ^Some Intel P67 MOBOs will NOT allow you to change the CPU Multiplier. Example the Intel DP67BA will NOT OC - confirmed. Whereas the Intel DP67BG does OC. Google yourself...

    BTW - I too was shocked that ANY 1155 Intel Mfg MOBO won't support a 2500K/2600K 'K' unlocked CPU OC.

    Example - I've seen 2 other posts @ Toms stating the same.
