Any plans to release memory with EXPO profiles for AMD Zen 4 / AM5?

    Yeah, I get that it's just a small amount of power, but it would be interesting to have more precise values. Things add up overall.

    The power consumption of dram is very negligible compared to other components like a CPU or GPU. We are talking a couple of watts per module at full synthetic load.

    Regarding these two models, the 64GB kit will require slightly more power, due to the additional ICs required to build 32GB modules and the higher E.X.P.O. voltage.

    Thanks.

    If comparing 64 GB and 32 GB kits like these:

    64 GB model lists voltage as 1.40V.
    https://www.gskill.com/specification...-Specification

    32 GB: 1.35V
    https://www.gskill.com/specification...-Specification


    What is the difference in power consumption for them in Watts in the sense of planning what power supply to use?

    Zen 3 DDR4 does not have quad channel so DDR5 Zen 4 would surely be better.

    Even with higher capacities and latency, DDR5-6000 with Zen 4 will be faster than DDR4 Zen 3.

    If comparing, does increase in memory bandwidth in DDR5 when used with Zen 4 compensate for lack of quad channel when comparing to optimal spot for DDR4 with Zen 3?

    I.e. to put it differently, will let's say 2x32 GB 6000 MT/s DDR5 with Zen 4 be faster than 2x16 GB 3600 MT/s DDR4 with Zen 3 or the same or even slower still? (Assuming comparing options with lowest offered latencies for those kits).

    Yes, less capacity is slightly quicker and DRAM specs are slightly better. Naturally, higher capacity requires more refresh time, latency, and memory locations to access. However if you need the capacity then it is simply something that needs to be accepted. It would not be a significant slow down, in fact most people likely would not notice a difference.

    Another question about 64 GB kits. Since they are dual channel and Zen 4 favors 2 sticks set up, will 32 GB be faster than 64 GB or they are comparable?

    Looks like at least CL32-38-38-96 64 GB kit is listed! (I don't see it in stores yet though).

    Non RGB 30-40-40-96 one isn't listed yet, but there is RGB one.

    Keep an eye out on the G.Skill Press page as any new information will be there first:

    Any news on the DDR5-6000 2x32GB EXPO kits yet? Are they going to be available this month or later?

    As long as the memory is configured properly it should be capable of outstanding results. For any profile, the motherboard must be able to recognize and set memory correctly, and hardware must be able to support full memory kit specifications.

    May be a few more weeks before vendors are able to get the higher capacity kits officially up for sale. Within the USA, you should see them on NewEgg.com
    Many thanks. Do you know if part numbers have been issued for the Flare X5 6000 and 5600 64GB kits (to make sure I'm looking for the right parts)? If so, do you know where I could find these?

    If ASUS states an XMP model is compatible, then it is likely they have provided XMP support for the motherboard model/BIOS.
    Understood, and thank you (I tried to educate myself a little and understand that Asus is using DOCP / their own rule sets to resolve XMP profiles to the AMD platform; I'm curious how much more performant manufacturers like G.SKILL have found native EXPO profiling to be).

    Anyhow, again, thank you very much for your time.

    If ASUS states an XMP model is compatible, then it is likely they have provided XMP support for the motherboard model/BIOS. A memory kit will either have XMP or EXPO, so official support of one or the other, or both, will depend on motherboard model and manufacturer.

    Thanks, G.SKILL, for putting out great products.

    Saw the press release (referenced in OP, re-linked, below) referencing Expo 64GB Flare X5 DDR5-5600 (2x32GB) at 28-34-34-89 and DDR5-6000 at 32-38-38-96.

    https://www.gskill.us/forum/forum/general-discussion/what-s-new/168556-g-skill-announces-trident-z5-neo-flare-x5-series-ddr5-memory-for-amd-ryzen-7000

    It says kits available via G.SKILL's worldwide distribution partners, in September, but I can't find part numbers or paths to purchase.

    Can you provide guidance (when / where available, or how to purchase)?

    Also, question for you. You write (emphasis added):

    Correct, so memory kits will either be XMP or EXPO, however it is likely some motherboards / BIOS will eventually be able to support either.
    Asus' X670E ProArt motherboard documentation lists support for G.SKILL F5-5600J2834F32GX2-TZ5RS at 5600, however, I see on the G.SKILL site that the RAM is listed as XMP (no mention of Expo):

    https://www.gskill.com/product/165/3...34F32GA2-TZ5RS

    Based on the quote above, does this mean that the part number is incorrect, and that this RAM lacks Expo support (or perhaps the documentation from Asus is in error / non-authoritative)? Or (edit) that the part will work, but the basic overclocking will be done via XMP rather than Expo profiles (I think this is the case)?

    Sorry for my ignorance, and thanks for your time...
