Hi guys, I know this has been discussed a lot on these forums. Trust me I’ve searched for answers and read a ton of threads. The problem is there is a lot of contradictory information. Basically it’s pretty much impossible to find the go to RAM kit most people recommend for this configuration (F4-3200C14Q-32GTZRX) at a reasonable price in Canada. I’ve found an alternative kit (same timings, Samsung Bdie, and I don’t care about RGB - F4-3200C14D-32GVK ), but I’m not sure whether I will run into compatibility problems. I plan to purchase 64GB for now, with the option of beefing up to 128GB down the road.
I was worried about the same thing. I’m not on threadripper, currently 2700x. I was worried about the G.SKILL Trident Z Series 32GB (2 x 16GB) DDR4 3200
[ F4-3200C16D-32GTZSK ] not being able to hit xmp. But once xmp was on, no issues. I couldn’t justify an extra $100($200 @64GB) for CL14.
Stock timing 16-18-18-36. Tried lowering, but it’s no point (hynix), just crashes. I can increase up to 3400 w/1.4 on volts. 3200 is fine at 1.35. Still running memtest to make sure it’s stable.

Update, the above on memtest gave errors. Drop the 3400 to 3333 @ 1.4. Ran memtest twice with no errors.
Machine is put together and up and running, a few observations:
Machine will not post with either XMP profiles. Whenever either XMP1 or XMP2 are set it fails to post 2 times then resets to 2133mhz
The system is stable in Memtest running @ 3200 mhz 14-14-14-34 @ 1.38V (I ran a 14 hours test with 2+ passes, no errors). Unfortunately though at this configuration some of the cores crash every time I run Prime95 (in about 2 minutes the first core goes, then 4 to 5 crash in the next few minutes, haven’t tested any longer than that). I’ve tried upping the SOC voltage to 1.18 and the ram to 1.4V and it lasts a bit longer, but still crashes.
Both Memtest and Prime95 are stable @ 2933 14-14-14-34 @ 1.35V. This is probably the configuration I will be going with.
The kit is Samsung B-die ram.
Running Precision boost overdrive and the ram clocked at 2933, I was able to push close to 3500 (3487) in Cinebench R15. Just for fun I ran a test with the ram at 3200mhz, and the score boosted up to 3523 (the system though is very unstable, the USB ports kept intermittently turning off).
The ram was expensive at 378CAD per 32GB kit, but it was a lot more reasonable than the ~560 per kit for the Trident Z kit (F4-3200C14Q-32GTZRX). I’m happy with the results.
