From what I have read, 32GB is just not as stable at this time with this RAM. You may be able to run 32GB at lower settings. I love this RAM too, but am satisfied at 16GB.

 

I think it's 4 sticks are causing more stress on the mem controller, that's why lower speeds. I went for 32GB as well but with two 16GB sticks. Can't confirm yet, I will have time to rip my PC on Saturday but I did research this before and this were my conclusions.

 

The new F4-3200C14D-16GTZR kit is running rock solid on my C7H. Can't speak to the 32GB kit.

 

I spent almost a month with the Trident Z RGB F4-3200C14D-32GTZR kit before I gave up. I couldn't successfully run the sticks at the advertised speeds. I ended up getting the F4-3200C14D-16GTZRX, which is only 16GB, but is advertised to work on the AMD boards. I got the kit to run using Ryzen RAM Calc's Fast Settings. MemTest Pro runs without issue for over 24 hours. However, RAM Test, at times, can find errors within an hour. Also, I was out for a week and when I came back, it struggled and downclocked to 2133mhz. I feel somewhat defeated, but I'm trying to work through it. I'm hoping for a BIOS update that fixes all of my issues...

 

I must say this is strange. I'm either dumb or lucky..I have exact same kit (F4-3200C14D-32GTZR) and exact same board (Crosshair VII Hero). Yes, it initially booted with 2133MHz if I remember correctly, but all I did is changed memory profile to D.O.C.P Standard, that selected 3200MHz-14-14-14-34 from the dropdown that appeared under this option and..it works.

 

Yeah. I wonder if I just had a fickle kit. I went through three kits: the Dual Rank B-Die (32GB), Single Rank SK Hynix (16GB...mistakenly ordered), and then the Single Rank B-Die (16GB) everyone raves about. Overall, I think I got the best stability out of the SK Hynix, but it was rated at CL16.

 

I admit I did not do any stress testing, but since Saturday I've put everything together I'm not getting any crashes, freezes and any instability..it just works at advertised speeds. Maybe I'll find some time next weekend to run some tests.

 

Cool I got the 16gb kit, but I'm thinking about getting another 16gb. What BIOS version did you use when getting the kit running?

 

I have the single rank 16GB (2x8GB) 3600 15-15-15-35 TridentZ kit and I am running through several tests at 3600 14-14-14-34 and tried all the way up to 3666 14-14-14-38. At 3666 I couldn't really get prime95 to run long enough to move on to a longer test at the voltages I wanted but someone else might. So I am back to test 3600 14-14-14-34 which I gave up on earlier but decided to try again with VTTDDR @.8 and trying DRAM voltages ranging from 1.45v to wherever I end up.

Sorry I know it isn't RGB, but I wanted to express my pleasure with Samsung b-die after having tried a Hynix kit first.
