I’m looking to grab some 8200/8400 DDR5, and maybe run it at ~8000 MT/s or so and tightly trim timings. I’m semi-planning to water cool the RAM, based on what I’ve been seeing regarding most people’s overclocked RAM temperatures. Hoping to get some feedback from those of you running OC DDR5 (7000+ MT/s). What cooling you use?

Regarding build, I’m going APEX ENCORE and 14900k - so I don’t expect to be limited from the IMC.

    Yeah, I’d love to hear how your encore runs along with the RAM.

    My goal is to keep the dimms under 40C, and so far water seems the only way based on what I’m seeing others say. But - if those heatsinks paired with a high CFM fan on top do the trick, I’d have no issue going that route.

    Keep me posted buddy

      Know it’s 2 weeks out, but I was quite wrong about the Bykskis

      If your goal is to keep them sub-40 the Bykskis will work

      Even running RAM Test they’re usually sub-40c but their peaks are pretty up there

      (active cooled with a 120mm + Encore fan, Bykski heatspreaders, Thermal Grizzly 1,5mm thermal pads)

      A fan even running at 3k RPM directly on the dimms won’t get you below 40C. At least not with the Gskill 2x24 kit I have. Best I can do during stress testing is 41-42C (25C ambient) at 8200C36 and 1.52v VDD. This is with a 3k Noctua Industrial.

        Yeah I’m not doing a 3k industrial on my ram for a daily rig. I’d smash it after an hour with the drone 😅😅🫠

        Was considering an A14 or A20 on a custom mount hanging from the top of the case: going into a Fractal Torrent, so no top fans

        Long term planning on doing a 3d printed blower style forced air setup like I’ve seen a few people here on Reddit do

          Well I only run it at high RPM for stress testing. Running it at 1000-1200 RPM is enough to stay below 40C for my daily use, mostly gaming. So it’s not loud at all.

      So, this is preliminary as it’s only been ~4 hours:

      XMP I, No ram modifications (stock heatspreaders), no direct active ram cooling ourside of the AIO pump’s fan, and 3 pull fans blowing over the mobo as if it were in a case (it’s on its box, no case open air)

      ambient is 69°f/20.5°c

      This is the kit of ram:

      14900k, 4090, z790 encore, 420mm aio (arctic ii + Kryosheet)

      Unbelievably it still hasn’t errored even though it’s neared 80°c on the ram I’m so intrigued I’m tempted to just leave it like this until it does lmao

      You’re going to hate me for this once you see their pricetag and shipping costs:

      Web search: " Apex Stealth Fans Alphacool "

      Look at their CFM and chart data
