But I guess it is good for people who just plug and play. It will offer a little better performance compared to 2133 JEDEC.

And, this FlareX doesn't seem too bad, considering many recent high bins fail on the same test. It could be much worse, plus voltage tolerance is higher than expected.
I just want to make sure, did you get the 3200 at 14 timing through 4x8gb even with the 3600 CL17 kit?? Can I achieve those numbers with a 2x2x8gb kit running at 3600C17?

Thanks for confirming

Was the 4x8gb 3200 C14 achieved with 4x8gb 3600C17 or a mix of the 3600 and 3733 kits? Please provide us with more details

I have 2 kits: One is older (Jan 2016) 3600C17 (17-18-18-38 XMP) and the other one is more recent 3733C17 (17-17-17-37 XMP).
The 3200C14 test was done with both kits in a 4x8GB combination. Both kits do 4000+ 12-11-11 on Apex motherboard.

So I thought it might be good to add my tests with the same model on Ryzen.

Test system was 1800X on air, running on Asus Crosshair VI Hero with bios 0082.


First I started with XMP. Worked without issues and I was able to lower the voltage down to 1.325V.




Next, I simulated a "standard" 3600C16 rated kit, which also worked flawless.




Last thing I tried was tightening the timings to XMP values on the same 3600MHz.
Obviously a bump in voltage was required, but I still consider this on the safe side for 24/7 operation.




This kit is weaker than my best B-Die, but still pretty decent.
More than 3600MHz on Ryzen are not really viable for 24/7 at the moment, even this is pushing it, because you need rather high bclk to achieve such speeds and might have problems with various devices attached to the PCI-E lanes.

I've also tried C12 and C11 - all worked with voltage increase.
Haven't checked them on Apex yet and don't know voltage tolerance and max Pi32M with wazza.

Overall it's a good memory, however if you own other good B-Die kit, there's no point changing it. You can also buy a higher bin B-die, they will still work at same timings on Ryzen.
Another thing is my IMC seems to be above average, so you might not be able to get same results at 3600, but 3200 should be no problem on 100MHz bclk with 3200 ratio or with higher bclk and lower ratio.

Good work and thanks for the results, really interesting to see how AM4 has now a decent start for AMD and DDR4

Is the G.Skill FlareX DDR4-3200 C14 compatible with Intel Z170 MB like Asus Maximus VIII series? Or are these strictly AMD only? I can not seem to find this information so far. TIA for any help

The FlareX worked perfectly on Intel Z170, very good memory

Thank you. I thought that was the case, from reading the OP second to last sentence, I quote: "Interesting fact, the sticks also state Intel XMP ready, means a profile on Intel platforms can be loaded."

However, others have posted information that made me question if these mems were intel compatible.
