Just put together a first gen Threadripper build for work a few months ago where out-of-the-box ECC support was too good to pass up for a box with >= 64GiB DRAM

Just put together a first gen Threadripper build for work a few months ago where out-of-the-box ECC support was too good to pass up for a box with >= 64GiB DRAM. If it’s possible to do a drop-in upgrade (cooling solution not withstanding) then this will be a big deal as we have basically not seen backwards compatibility, especially with such a compelling upgrade, in this part of the market in over a decade from Intel.
But 16 to 32 cores is a leap (250W TDP!!!!!), so I wonder what cooling solutions will remain viable (e.g., what about the TR4 edition Noctua cooler made just for TR?)
- dabockster 8y agoCooling Threadripper has been my issue with adopting it as well. The only pre-assembled cooler I've seen is an Enermax AIO block. Otherwise, you have to loop it on your own.
- loser777 8y agoDo you mean for liquid-cooled solutions only? We've been using this Noctua U14S TR4-SP3 (https://noctua.at/en/nh-u14s-tr4-sp3 https://noctua.at/en/nh-u14s-tr4-sp3) on a 1950X (no overclock though) without issues.
- reilly3000 8y agoOh man, I love that fan. But I misread the height specs on it and I couldn’t fit everything into my case any longer, but my old fan had died. I Ordered a replacement on amazon and the sent out the wrong item twice, so for about 3 weeks I just ran it open and yelled at the cats if they came in my office. Amazon finally gave up on trying to send the right case, and just told me to by it somewhere else, and eventually gave me a refund. I wanted to not take any chances, and the cats were getting terrified of me, so I ordered a ThermalTake core X9. The thing is insane. You could reasonably fit two motherboards and 8 hard drives in it. Don’t try to fit it on a desk. It could almost be a desk. But it is all worth it because I love that fan so much.
- dabockster 8y agoI did not know this was a thing. Typical Noctua coming to the rescue! How do the thermals compare with an AIO cooler? I've heard that their coolers come close to or exceed AIO cooling (assuming a standard Asetek Gen 5) on the usual square sized heat spreaders. Does Threadripper's more rectangular IHS impact temps at all with this cooler? EDIT: Just saw the bit about not having an overclock. Has anyone tried overclocking on this Noctua cooler? What were the results when compared to the AIO solutions?
- loeg 8y agoNoctua's U14-TR4/SP3 should work fine, easy peasy. And there are a ton of single piece AIO devices. No need for a custom loop.
- ihsw2 8y agoStarting with Threadripper 2, AMD will (optionally) be shipping a capable air cooler derived from their current lineup of air coolers (Wraith coolers). Faithful to its namesake, it will be called "Wraith Ripper."

- brian_herman 8y agoTake a look at this https://i.imgur.com/jT5iXWP.jpg https://i.imgur.com/jT5iXWP.jpg New cooler in the box of TR2
- sliken 8y agoIt's not actually that hard. AMD didn't cheap out on the integrate heat spreader (like Intel did) and it's HUGE. Commodity waterclocks on newegg already handle "500+ watts". I'm sure there will be a wide variety of solutions for 250 watts by the time they ship. It's really not that much power, many cases these days are designed for 3 or more 300 watt GPUs.
- loeg 8y agoJust for example, my first gen TR has this guy on it[0], which is already spec'd for 300W. I would think power delivery on existing motherboards only designed for 180W would be a bigger problem. But again, any board targeted at overclockers should already be prepared to handle at least 250W. The older boards will mostly just not support as much overclocking of the new, larger part.

- namibj 8y agoWith a good cooler you might be limited by the current handling of the socket pins. I'm interested in what solutions will be found to circumvent that issue.
- dragontamer 8y agoI hate to be the bearer of bad news, but that cooler is smaller than the Threadripper socket. https://www.gamersnexus.net/images/media/2017/CPUs/tr-1950x/amd-threadripper-coldplate-1.jpg https://www.gamersnexus.net/images/media/2017/CPUs/tr-1950x/... There are "proper" TR4 coolers, such as the Noctua TR4-specific air cooler which actually covers the entire socket, for a maximum connection between the radiator and socket. https://i.imgur.com/R0WbTSa.png https://i.imgur.com/R0WbTSa.png Pictured there is the Enermax TR4-specific liquid-cooler. There is another one on the market somewhere, I forgot the name though. Anyway, the bigger heat-plate makes a big difference. People have measured somewhere on the order of ~10C to ~20C cooler.
- simik 8y agoPower delivery by a motherboard might be a problem, too.
- loeg 8y agoDefinitely. On the other hand, many early TR boards were "gamer" boards and advertised overclocking ability. So they may have some power overhead to play with. Less overclocking ability with the old boards and the new 250W parts, of course.
- xxs 8y ago250W should be no issue per se, even 500W for 32 is not a lot at any rate and would not be hard for a 12 phase VRM to keep it stable. It may require an extra fan
- namibj 8y agoDon't forget the LGA pins.
- xxs 8y agoLGAxxxx is an Intel socket type, not AMD. If you look at the pinout of LGAs most pins are power related
- anonymfus 8y agoThreadreaper's TR4 socket is LGA socket with 4094 contacts.
- namibj 8y agoExtrapolating from Ryzen 1800X and a 16-core first-gen Threadripper, you'd overload the LGA pins at about 50% (300W) of the potentially possible ~600W you could make the chip take without sub-ambient cooling technology (and expect it to live for more than half a year at that level), i.e. with a forced-flow nucleate boiling cooler or a powerful waterblock. I once did some calculations for this, trying to find out if it could be worthwhile to wait for the 64-core EPYC and clock that one to like 3.5~3.8GHz, possibly with a governor that throttles the clock (and voltage) if the system is under low load. But assuming from some numbers I could find/calculate for how much less power they take, the predictions were so pessimistic that I did not pursue it further. (I did dream about a high-performance machine that could live in a case you could carry as a backpack, even though you'd probably not want to carry it very far due to the coolant being heavier than air.)
