Plus ECC support
- spamizbad 7y agoAny motherboards with LRDIMM/RDIMM support?
- soulnothing 7y agoUnfortunately not. That is the hard part. Rumored for the 64core and it's chipset next year. You can get 32GB ECC at 2666mhz Dimms that work. Giving you a max of 128gb ecc on an am4
- wmf 7y agoEpyc is there; you don't even have to wait to buy it. I know a lot of people are expecting Epyc features at Threadripper pricing but they also expected Threadripper to be much cheaper than it is.
- spamizbad 7y agoThreadripper is a workstation-class part currently capped at just 8GB per core (or 4GB per hw thread). That's not terrible, but it's also not great.
- Dylan16807 7y agoEpyc has much slower boost clocks. It's far less flexible. And people should expect features like memory support to be the same across the chips. Is there a reason nobody will take common 3600MHz chips and put 9 on a board instead of 8? Why is all the unbuffered non-ECC memory 50% faster than the unbuffered ECC memory?
- myself248 7y agoI have a hunch it might be partially due to vendors being willing to fudge their numbers for the sake of marketing. Selling into the gaming market, label it 3600 and if it crashes, they'll just tweak the clock and keep going. Selling into the server market, customers have a different expectation. Also many DDR-3600 modules can only run that way if they're the only DIMM on the bus. Populate two and you're down to 3333 or slower. Nobody runs a server with one DIMM, so again, the faster number simply doesn't apply to the ECC market, even if it's the very same chips. (Get more than two on the same channel, and you need to add buffers to drive the trace capacitance, which adds latency.) This suggests, perhaps, that you might be able to get some ECC DIMMs and overclock them all to hell and gone, if you're only running a single one per channel.
