suggestion for threadripper RAM

[noktek]

Hi guys im a bit confused about threadripper ram...
people say threadripper likes fast ram, but also say anything above 2666 is not supported (yet)
what is true? what should i do? whats a good set of 64gb ram and at what mmhz should i stop?

2666 is the officially supported speed however Threadripper will work with any memory module that works with the previous Ryzen CPU's depending on the board. This means you can use memory modules up to 3200 or higher if the board manufacture supports it.

but where do i find it? ive been googling different stuff but havent had any success

You want to find proof that Threadripper will run with ram with speeds faster than 2666?

Go to the third section of the article

https://www.pcper.com/reviews/Processors/AMD-Ryzen-Threadripper-1950X-and-1920X-Review/X399-Platform-Socket-Cooling-and-Me

"The highest memory speed supported without “overclocking” is 2667 MHz, and that is when running four DIMMs (one in each channel) that are single rank. If you want to populate all 8 DIMMs on Threadripper with single rank modules you will be limited to 2133 MHz, a significant reduction. Moving to dual-rank modules those speeds are 2400 MHz and 1866 MHz. Ouch. Thankfully, overclocking the memory on these platforms does not yet appear to be a concern. I have been running four DIMMs (single rank) at 3200 MHz on Threadripper without a hiccup and the performance improvement has been impressive. Just as we found with Ryzen, memory speed matters more here than on any previous AMD or Intel platform"

"Quad channel DDR4 Memory

AMD brought DDR4 support to Ryzen 3 5 and 7, but that remained dual-channel. With Threadripper that quad-channel support is being introduced. The motherboards will be paired with eight DIMM slots, configurable as single, dual and quad channel setup. AMD will support the standard Jedec SPD timings and frequencies at 2133/2400 and 2667 MHz, but you can expect to see motherboards with support for 3200 MHz (and higher up-to 3600 MHz) as well, much like Ryzen with AGESA 1006 and newer offers. Two channels per two 4 DIMMS per 2 dies and will offer UMA (distributed) versus NUMA (local) modes (for low gaming latency). The new memory subsystem will run 3200 MHz in quad-channel with no problems (with compatible memory). "

thank you for finding those! yes the issue is theres 3600mhz available and its really not that much more expensive than 3200 so it would make sense to get it probably but im not sure if it wold work

 

[noktek]

so this one would be ok?

[noktek]

actually this one is even cheaper and seems to have same stats?

My advice would be to check the memory compatibility list with the motherboard you plan to use the kit on. Next if you want to get the faster speed it may or may not work but even if it doesn't you can always running it at a lower speed.
