  • The good choice from 32GB to 64GB

    Hello,

    We have a new question for you, knowing that for our school of computer graphics in Montpellier (France), you helped us on March 2017 to choose the good G.Skill solution for our 49 computers. A very good choice! Thanks again.

    Here is the configuration of those computers:
    Case: Silent Base 800 Black be quite
    Ventirad: Dark Rock Pro 3 be quiet
    Power Supply: Dark Power Pro 11 750W be quiet

    Motherboard: Asus ROG Maximus IX Formula (DUAL CHANNEL, 4 DDR4-4133MHz slots, Z270 chipset, Socket LGA1151)

    Processor: Intel Core i7-7700K

    RAM 32 GB: GSKILL Trident Z DDR4 32GB (2*16) 3200 MHz CL14 (CL 14-14-14-34) F4-3200C14D-32GTZKW

    Graphics card: Asus GeForce GTX 1080 Ti ROG STRIX O11G Gaming

    Disc 1: Samsung 960 Pro NVMe M.2 SSD PCIe 512 GB
    Disc 2: Samsung 960 Pro NVMe M.2 SSD PCIe 1 TB
    Disc 3: WD Gold 10 TB SATA 3
    Screen: LG 38UC99
    Operating system: Windows 10 Pro 64 bits, version 1909 (2)

    Here is our question:

    1) It seems that the MAXIMUS IX FORMULA motherboard has 4 slots dedicated to memory modules:
    https://www.asus.com/fr/Motherboards...US-IX-FORMULA/

    2) Each computer already has two 16 GB modules, so 32 GB of physical RAM in total.
    > The reference of these two memory modules is:
    GSKILL DDR4 32GB (2*16) F4-3200C14D-32GTZKW
    and this reference is compatible with this motherboard.
    > These two modules installed since October 2017 work very well, without problems.
    > We chose them after comparing the performance of all competing modules and we absolutely want this particular reference, especially for its exceptional reliability, its performance and its huge margin of safety in overclocking:
    the GSKILL Trident Z DDR4 3200 MHz CL14 (CL 14-14-14-34),
    which is compatible with the Intel Z270 chipset (of this motherboard)
    > We chose this 2x16GB kit rather than the 4x8GB kit, because we have been told that in case we want to go from 32 GB to 64 GB, we would simply have to add two other modules 16 GB.

    3) Thus, on each computer, two of the 2 slots are already used and 2 remain free.

    4) We now urgently need 64 GB of physical RAM and, for that, we think we can simply add two other 16 GB modules on the 2 free slots.
    >> Is it possible? YES - NO

    5) For the sake of consistency, it seems to us that it is better for the 2 new modules to be identical to the 2 modules already in place rather than mismatching the installation.
    >> Is this correct? YES - NO

    6) In conclusion, we need to know if you confirm our choice
    to keep the 2 GSKILL DDR4 32GB modules (2*16) F4-3200C14D-32GTZKW already installed
    and simply add 2 GSKILL DDR4 32GB modules (2*16) F4-3200C14D-32GTZKW
    >> YES - NO


    7) We come to you because the technical support of ASUS answered “no”, without explaining why (what could be the risk):
    Mr Dhieb: servicecenter_emea@asus.com

    8) He said that we can find in the QVL list the “memory modules compatible with the motherboard in 4DIMM”:
    https://dlcdnets.asus.com/pub/ASUS/m...810.1568622131

    9) I think we found them on page 5, but we are afraid of being wrong.
    >> Is this the good reference F4-3200C14Q-64GTZ64GB (16GB*4)? YES - NO
    >> If not, can you give us the good reference?
    >> On the G.Skill website, under QVL oh this module, we did NOT see compatibility of this kit with the Intel Z270 chipset,
    nor with our MAXIMUS IX FORMULA motherboard:
    https://www.gskill.com/qvl/165/326/1...14Q-64GTZN-Qvl

    10) Does it mean that we have to throw away the 49 kits of 2*16 GB modules already in place and replace them with a kit of 4 other 16 GB modules? YES - NO
    >> The problem is that we have the budget to buy 49 kits of 2*16 GB modules, but not for 49 kits of 4*16 GB modules.

    11) The technical support of ASUS invited us first to "use one so as not to have a problem". Does this mean that we should buy those kits of 4 modules and first install only one of these modules to test it and see if it turns out really compatible? YES - NO

    12) The last but maybe the main question would be:
    In our situation, what would be your solution, knowing that since 2017 you released new products and knowing that we need exceptional reliability, perfect compatibility with this motherboard, top performance and huge margin of safety in overclocking.

    Thank you for your attention, because we are really afraid of making a mistake.

    Hello

    We can surely help with this. The concern is there no guarantee separate kits, even of the same exact model, can work well together. Only each 2 * 16GB kit has been matched and tested to work together, not as 4 * 16GB, so we can not be certain of the results. However, since you already have the RAM, the best solution, if possible, is to try pairing two kits in a single system and see if you can make ~24 kits. This can allow for some systems to use a matching 64GB set such as F4-3200C14Q-64GTZ

    This kit is compatible, no issue here, the question is how many existing kits can you match to run at full speed. For a school environment it can also be tricky if not all systems are in the same area, so mix matching and testing may be much more difficult.

      Hello,
      Thank you for your reply.
      I understand now.

      Could you explain what means “see if you can make ~24 kits”?

      I think we are going to replace the 2*16GB by your 4*16GB.

      So here is our last question:
      In our situation, what would be the best kit of 4*16GB DDR4 = 64GB), knowing that since 2017 you released new products and knowing that we need:
      - exceptional reliability,
      - top performance,
      - huge margin of safety in overclocking
      - and perfect compatibility with this motherboard:
      Asus ROG Maximus IX Formula (DUAL CHANNEL, 4 DDR4-4133MHz slots, Z270 chipset, Socket LGA1151)

      Thanks again.

        Currently you have 49 kits from initial purchase, you can try to see how many sets can mix match and work together as 64GB in a system. This way you don't need to buy 49 new kits, depending on how many existing sets can work together as 64GB. But I'm not sure how feasible it may be to do that testing for the school environment but it is just an idea so you don't need to purchase 49 new kits.

        With that motherboard and CPU, same exact spec would be best. Each system can be overclocked to push higher, but it is not worth the cost to jump another level up and pay that premium.

          Hello,
          Thank you very much for contributing to our decision.

          We also want to test a 4 * 16GB kit

          What would be the best series for 3D animation and special effects (on the ASUS Maximus IX Formula motherboard):
          Trident Z, Sniper X or Ripjaws V?

          Finally, we want to know what differentiates these three kits, between which we need the best performance:
          F4-3000C16Q-64GSXKB: Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
          F4-3000C16Q-64GSXFB: Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
          F4-3000C16Q-64GSXWB: Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)

          Thanks again.

            They are all same, only difference is physical heat spreader appearance.

                Hello,
                We were told that the amount of RAM influences its operation and that with 64 GB it is likely that the computer cannot keep up to 3200MHz / Cas14.
                > What do you think?

                For the ASUS Maximus IX Formula motherboard, G.Skill indeed recommends a maximum of 3000Mhz/Cas14 for a 4*16GB kit:

                Trident Z Series :
                F4-3000C14Q-64GTZ : Trident Z DDR4-3000MHz CL14-14-14-34 1.35V 64GB (4x16GB)
                F4-3000C14Q-64GTZR : Trident Z RGB DDR4-3000MHz CL14-14-14-34 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GTZR : Trident Z RGB DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GTRS : Trident Z Royal DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GTZN : Trident Z Neo DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GTRG : Trident Z Royal DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                Sniper X series :
                F4-3000C16Q-64GSXKB : Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GSXFB : Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)

                Ripjaws V :
                F4-3000C14Q-64GVR : Ripjaws V DDR4-3000MHz CL14-14-14-34 1.35V 64GB (4x16GB)
                F4-3000C14Q-64GVR :Ripjaws V DDR4-3000MHz CL14-14-14-34 1.35V 64GB (4x16GB)
                F4-3000C15Q-64GVR :Ripjaws V DDR4-3000MHz CL15-15-15-35 1.35V 64GB (4x16GB)
                F4-3000C16Q-64GVRB :Ripjaws V DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB)
                F4-3000C14Q-64GVK :Ripjaws V DDR4-3000MHz CL14-14-14-34 1.35V 64GB (4x16GB)

                But Asus offers us the following choice (all in 3200 MHz):

                  LDLC offers us the following kit:
                  G.Skill Trident Z Neo 64 GB (4x16 GB) DDR4 3200 MHz CL14 - PC4-25600 - F4-3200C14Q-64GTZN
                  I myself chose this kit on page 5 of the QVL document provided by ASUS support:
                  https://dlcdnets.asus.com/pub/ASUS/m...15346810.15668

                  However, in the page dedicated to this kit on the G.Skill site, I do NOT see compatibility of this kit with the Intel Z270 chipset of the MAXIMUS IX FORMULA motherboard:
                  https://www.gskill.com/qvl/165/326/1...14Q-64GTZN-Qvl

                  LDLC claims that the Intel Core i7-7700K processor is designed to operate 2400 MHz DDR4 memory modules and that it is unlikely that it will be able to operate four modules together at a frequency of 3200 MHz.
                  >> What do you say?

                  ASUS support told us that the modules proposed by ASUS "can" rotate at a frequency of 3000 MHz. But we want to know:
                  1) if the Intel Core i7-7700K processor can operate four 16 GB modules at a frequency of 3200 MHz;
                  2) if the reference F4-3200C14Q-64GTZN is compatible with the MAXIMUS IX FORMULA motherboard;
                  3) if the choice of this reference can cause any problem (instability or other);
                  4) if the reference F4-3000C16Q-64GSXKB - Sniper X DDR4-3000MHz CL16-18-18-38 1.35V 64GB (4x16GB) is a better choice and why;
                  5) if you offer a better choice, knowing that we need:
                  - perfect compatibility with the MAXIMUS IX FORMULA motherboard,
                  - exceptional reliability,
                  - superior performance
                  - and a large margin of safety in overclocking.

                  Thank you helping our choice..

                    1) Results can vary with each CPU, but 'K' series CPU typically will work fine which is why we recommended DDR4-3200 C14. Worst case scenario you can manually set to DDR4-3000, or boost VCCSA Voltage to stabilize DDR4-3200, so surely there is no real problem.

                    2) No problem

                    3) No problem

                    4) Lower frequency and performance so it may be less stress for CPU, but that is probably the extent of being any better at all.

                    5) You requested the best choice first time around, rest assured that is what we offered.
