I am having a real hard time deciding on what RAM to get for my Threadripper build. Going to get the following:

  • Threadripper 1900x - Get this now and then upgrade to a higher core Threadripper 2, when they come out at the end of the year (1900x are under £400 now and save the money from not getting a 1920x or 1950x, and spend it on RAM, but don't want to go over the top either). I do want more threads, but I am thinking it will be better to wait for the TR2. With the 1900x, I will double my thread count.
  • Gigabyte GA-X399 GAMING 7 (Assuming that Threadripper 2 will work with this board)
  • LIQTECH TR4 240 CPU WATER COOLER
  • 64GB RAM
I have been looking at Gigabytes tested Ram list, but I think it is getting a bit out of date and it is hard to find ones on the list still for sale.

The G-Skill ones that are specifically certified for AMD don't seem to be available in the UK.

I could get 4 x 16gb or 8 x 8gb sticks. From what I understand, there is advantages and disadvantages from using single and double sided ram sticks and also 4 or 8 slots. If I was to go for 8 sticks, then 8 single sided sticks would be best.

I think I want to go for 3200 MHz ram and ideally CL14. Don't know how much of a difference CL14 and CL16 would make at 3200 MHz. I also understand that Samsung B-Die memory would be ideal. I am also assuming that the Threadripper benefits from higher speed ram as the bog standard Ryzen. Or, do I just go with 2666MHz ram that is cheaper (~£200)?

Ones that I have been looking at so far:
  • Corsair CMD64GX4M4C3200C16 Dominator Platinum DDR4 64 GB (4 x 16 GB ) 3200 MHz C16
  • Corsair CMD64GX4M8B3200C16 Dominator Platinum DDR4 64 GB (8 x 8 GB ) 3200 MHz C16
  • TRIDENT Z RGB 64GB (4X16GB) DDR4 PC4-25600C14 3200MHZ QUAD CHANNEL KIT (F4-3200C14Q-64GTZR)
  • Corsair VENGEANCE LPX 64GB (4X16GB) DDR4 PC4-25600C16 3200MHZ DUAL/QUAD CHANNEL KIT - BLACK
  • TEAM GROUP XTREEM " EDITION" 32GB (4X8GB) DDR4 PC4-25600C14 3200MHZ QUAD CHANNEL KIT - BLACK - Heard good things about this but very expensive.
  • VENGEANCE LED 64GB (4X16GB) DDR4 PC4-25600C16 3200MHZ QUAD CHANNEL KIT - WHITE LED
What are your thoughts or experience?

4x 8Pack 3200mhz C14 Dark Pro kits also working well in this kind of set up. I tried this out myself. Obviously depends on CPU IMC and tuning as to if 3200mhz is possible with 8 sticks, 3066mhz divider always fine for me.

Thanks 8 Pack! I thinks I can live with 3066mhz, if it comes down to that.

Did you mean Xtreme and not Dark Pro? https://www.overclockers.co.uk/team...3200mhz-quad-channel-kit-black-my-094-tg.html

Would the following be able to run at 3200Mhz CL14:

  • TEAM GROUP XTREEM " EDITION" 32GB (4X8GB) DDR4 PC4-32000C18 4000MHZ QUAD CHANNEL KIT - BLACK
  • TEAM GROUP XTREEM " EDITION" 32GB (4X8GB) DDR4 PC4-33000C18 4133MHZ QUAD CHANNEL KIT - BLACK

Strangely, the 4133MHz C18 ram is much cheaper, but on pre-order, and will probably go up in price when it comes into stock. Of course, when the stock comes in, is another question.

It's working perfectly in quad on every x399 board I tried at 3200 c14. Often 3333mhz too.

With 8 sticks. It works fine if imc is capable. If it's not then nothing will run. In all situations I tried 2933 bare min. 3066-3200 usual.

I ended up getting 4 x TEAM GROUP DARK PRO " EDITION" 16GB (2X8GB) (DDR4 PC4-28800C16 3600MHZ DUAL CHANNEL KIT - BLACK). I also ended up getting a 1920X instead of the 1900X. I just noticed that the price has just increased by £10 for each dual channel kit (total increase for 4 kits is £40), so I am lucky that I made the purchase when I did.

I got all 8 sticks running at 3200MHz and CL14 (Used the XMP profile). So far no issues.

Thanks for your help 8 Pack and orbitalwalsh.
