Got so many deals from this site so I figured I'd give back, if only a little.

Great RAM at the lowest price I have ever seen.
I'm fairly sure both of these speeds are confirmed Samsung B-Die but will update when the ones I bought arrive Thaiphoon reports both 4400MHz sets as B-Die; anything slower is hit or miss on that front from Patriot from what I've read online.

If you enjoy overclocking your ram it seems you can't get a better deal for this price.

    Is that a sign that DDR5 is just around the corner?

    • netsurfer on 27/01/2021 - 15:42

      You think Zen 4 and X670 boards are just around the corner?

          Almost no chance because AMD is making too much money right now and they haven't even released their entire Zen 3 lineup yet.

          You want devices which uses DDR5 as system memory? Get Samsung Galaxy S20 or better (or Xiaomi Mi 10 or better) - they use LPDDR5.

          With Intel lagging behind big time, it's hard to see DDR5 being used on PCs and laptops very soon. Looks like AMD will more likely be the one pushing it / using it first. However, what you can gain from DDR5 pales in comparison to a better CPU.

    A free tip from a system builder. While it may look enticing to buy super fast RAM the reality is pretty much no current motherboard and CPU combination can easily and stably run RAM at these high speeds without a lot of crashing, and that is if the PC boots at all. My emphasis is on ease and stability - I'm not talking to BIOS overclockers who are happy to voltage tweak for hours. You can buy this RAM if you want but you will almost certainly need to manually downclock it in the BIOS to run at 3200Mhz (or 3600Mhz if you're running the latest 3000 Ryzen's) in order to get the system to boot and run stable without crashes in Windows on current gen systems. Ryzen chips are actually designed to run slower if pushed too far on the RAM speed. Take or leave my advice from experience. The only other reason to buy this RAM speed is to try and "future proof" (i.e. use this DDR4 RAM one day in a future PC that may support those high speeds), however by then DDR5 RAM will likely be the norm.

    • 4foxache on 27/01/2021 - 13:58

      Yep 3600 on the ryzen 3000's is about all you can expect in most cases at 1:1 speeds… above that is pretty rare to achieve 100% stability.

    • FlappyFallz on 27/01/2021 - 13:59
      +2

      Yeah I gotta agree, unless you're adjusting the timings manually and down-clocking it's absolutely not worth it.
      Not a plug'n'play kit.

      *sorry, I meant to write "(or 3600Mhz if you're running the latest 5000 Ryzen's)", but it is true that some 3000 series Ryzens will also work at 3600Mhz, while 3200Mhz is safest for system stability.

      • 4foxache on 27/01/2021 - 15:09
        +1

        I have a 3600x that does 3600 fully stable… I think generally the X's at least in 3000 series have better luck at 3600 speeds and above

      • Davesday on 27/01/2021 - 19:05

        Yes, I have been running Ryzen 2700x on 3200MHz and Ryzen 3800x on 3600MHz RAM speeds. I also go for the most stable motherboards and update to the most stable BIOS releases.

        For Ryzen 5000-series users, I think they go for 4000MHz or higher RAM speeds inconjunction to higher IF speeds to match. It is not a guaranteed thing of course but newer AGESA releases are making things more stable for these configurations. Another use case for these crazy RAM speeds are to actually 'downclock' them with tigher timings. For example you could technically run a high performance 4000MHz RAM part at 3200/3600MHz speeds but with way tigher timings. This way you respect the 1:1 IF speeds without going out of specs like you would in the first use case.

      Just finished messing around with them for a couple of hours but with a 3700x and a cheap B450 board I can get 13-13-12-26 @ 3200 with no errors after running MEMbench on both kits I bought but YMMV.

          All tests were done 3 times to standardize the result.

          I just set the ram to 2400 with auto timings(c19) to compare, so it's basically best case scenario but…

          Cinebench R20 was all within margin of error; dunno if that's consistent with results online

    Download "DRAM Calculator for Ryzen". Choose memory type as Samsung B-die (99% sure the 4400Mhz will be bdie) and fill out your required frequencies and it will give you an idea what you can run. Should be something like this for the safe option (assuming you have a half decent motherboard and ryzen 2nd gen+):

    3200 14-14-14-14-30 safely.

    3600 14-14-16-15-30 safely.

    I have a few of these kits at 3400 @ around 14-14-14-14-28 with very tight sub-timings. I played around with running higher frequency's but after 3600 you don't get much gain and may even go backwards. I bought these kits as they were the cheapest bdie memory modules i could find and still seems to be the case.

    If you want to find out what memory modules you have ended up with once installed, use a program called "Thaiphoon Burner". Its not 100% accurate but should tell you what the memory type is that you can use in conjunction with dram calculator.

      Hynix DJR also is good at those timings… given the price I'd personally be guessing these are Hynix DJR

        I bought 3 of these 4400Mhz patriot Viper kits and 2x 4133Mhz kits and all were bdie. Although its pretty common for the chips to change but can't say i've seen CJR @ 4400MHz 19-19-19-39. Do you have any links to info on CJR running at those speeds from factory?

      • integral on 27/01/2021 - 22:05

        Nope, DJR won't be able to do tRCD 19 at 4000 let alone 4400.

        • 4foxache on 27/01/2021 - 22:32

          That's one measure I have a Hynix DJR kit that is rated SPD 18-22-22-42 at 4000. I run it every day at 3600 16-19-19-39 1T 1.45v. So with a bit of luck you'd probably go very close.

          • integral on 28/01/2021 - 16:28

            @4foxache: I haven't seen CJR do tRCD 20 at 4000 and DJR is pretty similar to CJR. It's impossible for either to do tRCD 19 at 4400 as it needs to be relatively loose and doesn't scale with voltage.

            • 4foxache on 28/01/2021 - 17:26

              @integral: DJR is effectively high frequency CJR so it does scale better. tRCD 19 at 4400 is shifting the goal posts a bit from your tRCD 19 at 4000 :)

              • integral on 29/01/2021 - 11:47

                @4foxache: Yes, DJR is high frequency CJR but the best I've seen is tRCD 19 at 3800. As I've said before DJR needs loose tRCD so 4000 19-19-19 and 4400 19-19-19 are not DJR.

    • netsurfer on 27/01/2021 - 15:49

      Unless you really know DRAM very well, it is better to use Thaiphoon Burner and read the actual RAM module data, rather than rely on DRAM calculator.

      One issue with using DRAM calculator is that most people tend to be over optimistic about their RAM modules. You do need to do proper memory testing if you elect to go manual with DRAM calculator. If you simply use Thaiphoon Burner to get basic info (instead of asking it to export the actual RAM settings) and then manually go in to DRAM calculator, it is not the right thing to do for most people (only the advanced users). It's somewhat disappointing Steve's youTube tutorial doesn't go through the proper way. While you have a better chance get away with things if you have B-die RAM modules, it is still not a good way for most people.

    • notmarounhindy on 27/01/2021 - 15:51

      I've OC-ed at least 2 dozen memory kits now from every manufacturer. Having used DRAM calculator lots, I can safely say:

      Things that DRAM Calc is really good with:

      Good bin B-die. Just increase the voltage beyond it's recommendation and you'll normally get where you want to go.

      Things that DRAM Calc is sorta good with (will throw errors without proper knowledge and serious testing):

      Micron E-die
      Decent bin B-die

      Things that DRAM Calc is not good with:

      Pretty much everything else.

      Micron kits generally get to high speeds, and CJR/DJR can too provided you have a good bin. These kits are likely B-Die, but given their price it is not advisable to suggest 3600CL14 as a 'safe' option. If you go backwards with higher frequencies then you're most likely unstable.

      • netsurfer on 27/01/2021 - 15:58

        I found that if you use Thaiphoon Burner to export the actual RAM timing information to the format DRAM calculator can import, you generally get a reasonably accurate information.

        However, if you just look at the Taiphoon Burner info to determine the RAM type (without actually getting all the timings), then you go to DRAM calculator and manually go through it, you would run into issues. That's because there are different grades of B-dies and Micron-E. If you prefer stability, use the exported settings, rather than tweak it manually in DRAM calculator. However, if you are an advanced user or you really want to push it to the limit, I guess you could manually tweak it, but you do need to RAM test the RAM modules properly afterwards.

      • trestylez on 27/01/2021 - 19:39

        "If you go backwards with higher frequencies then you're most likely unstable."

        I was referring specially to Ryzen and may not have been clear on that. In my experience once you loose 1:1 on the infinity fabric you pay a pretty hefty latency penalty that will be slower for most real world workloads. I memtest my settings for stability btw and most of my machines will end up 100% loaded for most of their life.

        Of course nothing is guaranteed, so buyers should understand that :)

        • notmarounhindy on 27/01/2021 - 20:07

          What do you use for stability testing?

          • trestylez on 27/01/2021 - 21:16

            @notmarounhindy: For memory i just use Dram calculators memtest under MEMbench which is a front end to the provided HCI memtest.

            • notmarounhindy on 27/01/2021 - 22:07

              @trestylez: If you're on Ryzen I'd recommend testing the IMC as well with y-cruncher and P95 large FFT. HCI is good but it tests RAM much more, so you can have cases where you're 1000% stable HCI but the IMC actually can't handle it when CPU is loaded too.

      B-die is good if you want to faff around with it, I tried a b-die kit and I got slightly more out of it than a DJR kit at 3600 but the effort resulted in like less than 1% percent performance difference so I was like no point waste of time.

    I couldn’t get it to run at 4400mhz on my 10900 + msi z490 gaming edge wifi (4 sticks), I think it can do 2 sticks at 4400mhz

    I works fine 4 sticks with xmp profile 2 which is set to 4266mhz cl19 1.35v which i was happy with

    Will tighten timings soon :)

    Best bang for buck high speed B die!

  • GafnYtHeLoRd on 27/01/2021 - 19:36

    Be warned, XMP will NOT work on non-Z Intel motherboards. Intel locked both CPU and Memory overclocking to their enthusiast-level Z chipset, so any other Intel chipsets will not go over 2666MHz (not exactly sure of the exact frequency, but it's there)

      I7 and i9 will go to 2933mhz on non z boards. But otherwise good info for anyone building.

      I bought the viper 4 series 3733mhz kit for $109 recently. It's hynix cjr but I'm very pleased with it. Runs stable no issues and provides great frame rate increase over 2666 and 3200mhz. I find this set to be the absolute true value ram right now. Better than the higher speed ram for $30 more (for non overclockers)
