    Hi in there
    I've seen RAM sticks with speeds like 2600MHz and 2666MHz on Newegg.com up for sale, are these stuff legit to work with 2400MHz only supported MoBo Like Asus X79 RoG Line up? and how if possible? only XMP? how come?

    maybe just clock it on bios or something, and well you might need a new mobo that support that speed, as most likely if you got a 2400 speed mobo and you got 8 of those it will run in 2400 once clocked, it's only my theory so someone should give a better answer

    Sir, I promise you, you will not see 2666mhz this year, or next year.
    DDR3-5333 wont ever happen, it will be DDR4-5333

    "Manufacturer Response:
    .
    Dear Customer

    We can certainly clarify the confusion you may have. Intel does NOT support overclocking, so DDR3-1600 is the maximum frequency they suggest. As a result, DRAM Voltage is also limited at 1.50V (standard). This memory kit is clearly not average, or standard, so of course it will not follow Intel's guidelines. As you know, Intel has had this DDR3 limitation for Sandybridge and chipsets prior, so it is nothing new. If you do a quick search for performance DDR3 memory, everything is above 1.50V. Rarely is <1.50V memory considered high performance.

    G.Skill produces the best (extreme) memory modules available on the market. Rest assured that the kits are tested for their specific platforms. With the proper settings, although much greater than Intel specifications, it will not harm your CPU. Similar to CPU frequency overclocking, 4.6GHz+ from 3.8GHz default (turbo) is common, but technically Intel does not support it. If you want to follow Intel and the standards, you will need to purchase DDR3-1600 CL11 or under.

    Thank you
    GSKILL SUPPORT

    Quality and customer service are our top priorities"

    I think its going to work, maybe your cpu is not going to support it, the memmory controller is in the cpu nowadays, i should pick up the kit, and see if you are lucky

    This are ment for 3rd gen 1155 ;)

    If you look at the z77 mb you see they go up to 2800 OC

    but won't work for the current X79 line up?
    and if so, why is there Quad Kits?
    and also does this mean Intel supports a "Mid Range" chip with more RAM OC than a High End one?! WOW!

    I'm not sure on how 2011 oc on the mem and 1155 does have 4 dimm slots


    They would work on x79 just not sure if they can run that high cuz I don't own a 2011 rig or looked up reviews on them

    2666Mhz DDR3 and Intel X79 chipset compatibility

    Hi all,

    I am new to this forum, but wanted to shed some light into the limitation in the compatibility between the new higher speed DDR3 desktop memory that has recently been released. Here is a list of 'facts' that will hopefully address some of the concerns some of you have posted:

    1) The Intel Sandy Bridge (SB) CPUs are equipped with an Internal Memory Controller (IMC) that only supports up to 2133Mhz DDR3

    2) The Sandy Bridge-E (SB-E) CPUs are equipped with an IMC that only supports up to 2400Mhz DDR3

    3) The new Ivy Bridge (IB) CPUs are equipped with an IMC that supports DDR3 memory up to 2800Mhz

    So, the bottom line is that you will NOT be able to make full use of 2600Mhz or 2666Mhz DDR3 when using a SB CPU with a Z77 motherboard or an X79 motherboard with a SB-E CPU.

    How do I know this? Simple - I own a 16GB (4 x 4GB) set of G.Skill Ripjaws X 2666 Mhz DDR3 memory that I bought off of Newegg last week and have attempted to use it in my Intel SB-E 3930K CPU and Asus Rampage IV Extreme motherboard (with BIOS 1305) and was unsucessful in running the memory at either 2600 or 2666Mhz memory speeds. I tried both manual and XMP settings to no avail. I also attempted to use both stock voltages (1.65V) and higher and switched from 1T to 2T command rate, but nothing worked. In fact, my motherboard would not even POST when attempting to use either 2600 or 2666Mhz speeds. Once I reduced the speed to 2400Mhz, the motherboard POSTed and everything worked fine. I went ahead and reduced the latencies from the stock XMP settings of 11-13-13-35 to 10-12-12-31 as I was running the memory at lower speeds. Everything worked perfectly now, and I have my 3930K overclocked at a modest 4.5Ghz @ 1.36V with no other voltage adjustments made - a testament that the Asus IV Extreme motherboard is truly the shiznit!

    Sorry for the bad news for those hoping to run the newer 2600Mhz and 2666Mhz DDR3 with their SB & Z77 or SB-E & X79 motherboard setups. I am very disappointed too. You might be able to squeeze out some Mhz (maybe even up to 2500Mhz with voltage tweaking/adjustments), but don't count on it. To give G.Skill credit, they do explicitly state that the memory is for Ivy Bridge and Z77 motherboard setups...something that I found out is indeed true :banghead:

    SB supports 2133 MHZ max on most Z77 boards.


    Both X79, if you have a good chip, and Z77 with Ivy, can do 2400 MHz ++. sticks rated for 2600 MHz and 2666 MHz are for Z77 and IVY.

    The P9X79 Deluxe lets me select up to 2400mhz with stock bclk. I'm currently running 2333mhz stably (@ 10-11-10-28) and I don't see why it wouldn't be able to go further. I'm sure this really depends on the IMC you get in your CPU and what kind of overclock, timings, and memory you have.

    Sure. I mean, my CPU is pretty poor, IMHO, but 2400 MHz is no problem. However, getting even 10 MHz more is nearly impossible, no matter what voltages and timings are changed.

    That defeats the purpose of getting memory that can run that fast then.

    even going down to 12x doesn't help. Unfortunately.

    well I'm not go happy with the gskill trident x 2400mhz they run stock and up to 2500 but that's about it....

    And for some reason they will not run cas9 or anything else below cas.10 even at 1600mhz :wtf:

    But my ripjaws can run 2600mhz and there stock 1600 6-8-6-24

    Got to run them 2400-2600 7-11-7-28 1T 1.8v
