    Can a motherboard take out memory when its RAM slots fail?

    MB has VRM that control V to the RAM and if these failed somehow sending a huge surge of juice when they went then yes they may have killed the RAM. I remember with DDR BH5 the V use to come from the 3.3v line and it had to be increased to ~3.7v for overclocking the RAM but any higher and the...

    Want to upgrade to a Ryzen 3000 (maybe 4000), and need to know about DDR4 and the AMD IMC

    Any 16GB sticks are most likely dual rank still.

    x58 triple channel memory performance vs modern dual channel configuations

    Even if a CPU\MB could handle that speed the memory controllers tend to become a bandwidth bottlneck where bandwidth doesn't continue to scale with increased frequency. Dual channel 4790K DDR3 is capable of higher bandwidth than the tri channel X58 DDR3 for this reason but bandwidth still hits a...

    x58 triple channel memory performance vs modern dual channel configuations

    RAM speed affects real world performance by improving the efficiency of the the CPU on cache heavy tasks so in games overclocking my RAM can improve CPU performance by up to ~30% which is more than overclocking the CPU itself but in other programs like Cinebench that fit neatly into the CPU...

    Patriot Viper Steel 4400

    c14-c15 may be possible @3600-3733 1.4-1.5v @4000-4133 you are looking at ~c16-c17 1.4-1.5v, but only if it's A1 as I doubt A2 would tighten up so easily. If it is using A2 layout then it will handle high frequency fairly well but only if you pair it with a high quality MB preferably with just...

    The go with ITX with 2x16GB or you will has empty PCI-E slots to keep you up at night. Ryzen 3000 should have no problems hitting 3600-3733 with 2x16GB with a decent MB\BIOS as the memory controller is a lot stronger than it was on Ryzen 2000.

    Help timming for ram

    Running GSAT from a linux USB boot for peliminary testing before loading into windows is a good way to reduce the chance of corrupting the OS https://www.overclock.net/forum/18051-memory/1718166-gsat-google-stressful-application-test-tiny-bootable-linux-iso.html But it seems to focuses on RAM...

    Help timming for ram

    Yeah most games are fairly GPU limited so increases to CPU\RAM speed are not very noticeable a lot of the time. Running HCI memtest over night is usually enough to be sure the system is stable but tweaking RAM can be a slow process with so many settings to test which is not for everyone.

    Help timming for ram

    Gains can be larger than overclocking the CPU but without the extra heat. The performance gains from higher RAM speed stack with the CPU OC so that it can become more noticeable with the two together. Here they tweak the sub timings on a 3600c14 kit which improves CPU performance up to ~10% for...

    Follow this guide for sub timings https://github.com/integralfx/MemTestHelper/blob/master/DDR4%20OC%20Guide.md For example you may be able to run tWR 10 tRRDS, tRRDL, tFAW 4, 4, 16 tRTP 8 tREFI 32000

    how hard or likely is it to successfully OC dual rank 2x16gb 3600 cl16 modules to 4000+ mhz?

    I am running 4x8GB 3200c14 in a older t-top MB 6700k max frequency with two sticks was 4000c17 2t 7700k 3600c14 1t with two sticks or 3600c14\15 2t with 4 sticks So 4 sticks didn't affect the max frequency for my system just timings a bit. Your plan sounds solid if you just want to buy a 4x8GB...

    how hard or likely is it to successfully OC dual rank 2x16gb 3600 cl16 modules to 4000+ mhz?

    A good MB improves the signal quality between the RAM and the memory controller making it easier on both. The quality of the MB lanes traced between the RAM and the memory controller and the thickness of the PCB has a lot to do with it as does it's BIOS. MB with two RAM slots that are made with...

    how hard or likely is it to successfully OC dual rank 2x16gb 3600 cl16 modules to 4000+ mhz?

    2x16 3600 16-16-16 will likely do 4000c16-c17 ok with ~1.45-1.5v with a good MB like Z390 Apex.

    4x16gb or 8x8gb for Threadripper

    If the MB was t-topology then 8x8 may be about equal to 4x16 but on daisychain MB 4x16 is much better. I have no idea what layout most threadripper MB use.

    Anyone use a RAM cooler?

    I found increased stability with Samsung b die when running over 1.45v with a Intel stock fan wedge in over the RAM especialy when running 4 sticks I was able to run higher speeds when the RAM stayed under 40c.
