Was discussing this previously in another ram deal but since I pulled the trigger myself just now thought I’d share.

It doesn’t have fancy RGB colouring but it is fast, plentiful and cheap by comparison.

Please note the 5% discounts brings the $350 down to $332.49 in cart.

    Fyi cl18

      lords work

  • Decent deal.

  • Good ram for Ryzen, just be aware of the adjustments you need for compatibility with Intel CPUs.

    • +4

      Ryzen works better with frequency than latency. Unless you have a link providing it being slower than a crap 2666mhz…

      • +2

        Regardless of latency I’m sure ~1000mhz can’t be snubbed off

    • +12

      This isn't slower than 2666Mhz CL16 in either bandwidth or latency. At 3600Mhz CL18 latency is 10ns, at 2666Mhz CL16 latency is 12ns~

      see this table for timing differences https://imgur.com/MhqKfkf

    • 3600C18 has the same latency as 3200C16, so it's still a fair bit better than a 2666C16 kit.

  • Did RAM get expensive again? I thought it was still on a downward trend.

    • Well this IS 64GB in the max increments of 32GB that’s generally available in consumer ram. It’s also faster at 3600mhz.
      I’d imagine 2666 can be had fairly cheap especially in 8 or 16gb sticks but for those of us with ITX or just want to future proof in general 32GB is the smart choice

      • Oh right, fair enough then.

        I'm still using my old 2666 (8gb x 2) sticks.

  • I need UDIMM dual-channel RAM for my Dell 8940.

    Is this suitable?

    • If it takes DDR4 and is recent enough to support 32GB sticks yea but generally only boards in last 2-3 years will take it and sometimes they need a firmware update

      • So this DDR4 RAM is…

        1. UDIMM
        2. dual-channel

        ???

        • Most decent or even almost all ram is dual channel, and UDIMM is desktop.

          It IS amazon, so return wise you’re pretty well covered, even if it turns out to have an issue.

          1. UDIMM is unregistered memory, this will work with the Dell 8940. Unregistered memory is the type normal desktops use, registered memory is specialised and if you need it you would know.
          2. Dual-channel is the configuration the memory is in once it's installed and 99% (as long as they're matched pairs) of the time which memory sticks you get won't matter as long as they're installed in the right corresponding slots on the motherboard.
          • @Trance N Dance: Just what I would’ve said if I wasn’t so lazy… and could articulate it.

    • install CPU-Z and click the memory tab and under general - identify your memory type (e.g. ddr2/3/4)

      now you have the basic knowledge to buy a suitable memory type!

      • is there a non-install app that does this?

        • CPUZ - just run it. No install needed.

  • Am I right in saying these larger sticks are harder to tweak than 2x16?

    • By tweaking if you mean overclocking then yes. You want 4x16GB if you want to overclock or otherwise 4x8GB is best.

      • wrong.

        Daisy Chain Mobo: 2x Single Rank > 2x Dual Rank >= 4x Single Rank > 4x Dual Rank. (don't even bother OC Quad rank )
        T-Topology Mobo: 2x Single Rank >= 4x Single Rank > 4x Dual Rank >= 2x Dual Rank.

        • You do know what ranks are right? The bigger the stick in terms of size the more ranks. That's my point.

          • @[Deactivated]: now you tell me, 16Gbit * 8 = 16G sticks, how many rank does this stick have? your point is wrong, your last post is wrong too.

            • @OMGJL: The memory in question are 32GB sticks. What are you talking about? How about you elaborate if you are trying to make a point. Given you are so much smarter than me take the time to educate me then.

              For others who want to get an understanding from a proper source rather than forum comments read this article. Here is a snippet which backs my initial response:

              "Most consumer-grade memory features a single rank, though higher capacity modules are usually dual rank, while server-grade memory is often quad-rank."

              https://www.techspot.com/article/2140-ryzen-5000-memory-perf…

              • @[Deactivated]: DDR4 Memory right now are made using either 8Gbit chip (1GB capacity per chip), or 16Gbit chip(2GB capacity per chip)

                In order to make a 8G stick, you'd need to use 8 of 8Gbit chip, all 8 of the chip are usually on one side, being 1 rank.

                for 16GB stick, you might use 8 of the 16Gbit chip, all on one side, being single rank as well.

                You could also use 16 of the 8Gbit chip, 8 on each side, 1 rank on each side, this stick is dual rank.

                so a 16GB stick could either be 8Gbit dual rank, or 16Gbit single rank.

                a 32GB stick could be quad rank 8Gbit, or dual rank 16Gbit. Although quad rank is very rare, so you can assume a 32GB stick are dual rank 16Gbit.

                Now you see, assuming the chip overclocking behavior be identical, 4x16GB single rank will OC exactly the same as 4x8GB single rank.

                Why flame me while you have absolutely no knowledge on RAM?

  • Is this single or dual rank?
    Suitable for 2 slot 550B-I ryzen 5600x ITX?

    • I’m not sure… I used some recent TFORCE 32GB sticks on my previous generation X470 with a 2700X, so… I’m not anticipating a problem with my intended Ryzen 5X00.

    • I've got the equivalent Patriot Viper Steel sticks (apparently only aesthetically different to the Blackout series) and they're Hynix dual-rank. They work fine in my B450I mini ITX motherboard (after a BIOS upgrade) so there's no reason they wouldn't work with a 550B-I - best to check the MB RAM compatibility list if unsure.

    • Single rank 16gb sticks just starting coming out so 2x32gb should definitely be dual rank.

  • I am currently running 2x 8GB Crucial Ballistix 3600MHz C16 (Rev.E) on my 5800x ITX build. Would I lose much performance going to this set at C18? Thought I should use more RAM although it is not really dire at this stage.
