Greetings
My Z390 FTW is set to arrive tomorrow. I have 8x4 (32gb) G Skill F4-3200C16D-16GVK from a previous build. I don’t see this memory on the compatibility list. Is anyone currently using this memory on this board? My CPU is i5-9600K.
Thanks

Have you checked on the G.Skill site ? GSkill RAM Configuator
 
GSkill & EVGA & Z390FTW
 

I did and they are! Thank you kind stranger.

An EVGA Z390 FTW is on the QVL for the G.Skill F4-3200C16D-16GVK RAM..You should be good to go 

Happy to Help

Heh.  I saw this for the first time yesterday and whaddayaknow?  My G.Skill memory is not on the list and that is probably why it won't even boot with the XMP profile selected.
 
My Z390 FTW (bios v1.08) with i9-9900K o/c to about 5.2 GHz (turbo, goes back to 4.9 GHz on all cores under longer full load) is currently running it at the default of 2133 MHz instead.
 
The memory I have is a pair of F4-3600C19-16GSXKB 16GB DDR4 DIMMs. (https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232741?Item=N82E16820232741)
 
Data from HWInfo:
 
The XMP profile:
Module VDD Voltage Level:                                                       1.35 V
Minimum SDRAM Cycle Time (tCKAVGmin):                                           0.55500 ns
CAS# Latencies Supported:                                                       19
Minimum CAS# Latency Time (tAAmin):                                             10.454 ns
Minimum RAS# to CAS# Delay (tRCDmin):                                           10.899 ns
Minimum Row Precharge Time (tRPmin):                                            10.899 ns
Minimum Active to Precharge Time (tRASmin):                                     22.125 ns


Supported Module Timing at 1800.0 MHz:                                          19-20-20-40
Supported Module Timing at 1733.3 MHz:                                          19-19-19-39



The rest of the supported (i.e. tested?) settings are:
Supported Module Timing at 1066.7 MHz:                                          15-15-15-36
Supported Module Timing at 933.3 MHz:                                           13-13-13-31
Supported Module Timing at 800.0 MHz:                                           11-11-11-27
Supported Module Timing at 666.7 MHz:                                           10-10-10-22


It is currently running at 1.2v and 1066.7 MHz clock settings above (15-15-15-36 timings) which appear to be in-spec.
 
It seems that the MoBo wants a CAS of 14 for 3200 MHz memory and 16-17 for 3600 MHz based on the memory compatibility page referenced above (https://www.evga.com/support/motherboard/).
 
My question is this:  Can I put some timings into the BIOS manually and get the CPU/MoBo/Memory to work together appropriately at a higher speed, even if it isn't 3200 or 3600?  Or should I cut bait and just get some properly spec'ed 3200 or 3600 memory and sell the memory I have?

F4-3600C19D-32GSXKB 
 
G.SKILL memory naming convention/nomenclature:
 
F4 = DDR4
3600 = Frequency
C19 = CL Timing
D = Dual module kit (x2)
32G = Total capacity (32GB)
SX = Series (Sniper X)
K = Color (Digital Camo-Black)
 
*If there is a "A", "B" or "C" as the third letter of the series, such as "TZB" or "RKB", then it typically designates a different CL timing value when compared to the original model without the "B" in the third letter.
 
I think those specific modules are compatible, but just haven't been tested by G.SKILL or EVGA for that specific motherboard and consequently are not on either QVL..However, they have been tested/certified in similar Z390 chipset motherboards made by ASRock, Asus, Gigabyte and MSI.
 
X.M.P. Profiles may not be compatible though, as in many cases..So you should manually set the Frequency/Timing/Voltage to the rated specs of 3600MHz 19-20-20-40 1.35V in the BIOS and with a CMD (Command Rate) of 3T/3N, or 2T/2N, and if you're really lucky, 1T/1N will work..The CMD Rate is a big deal..Or, pick an X.M.P. Profile that has the rated Frequency/Timing/Voltage spec. (But it might have an incompatible/faster CMD Rate that's causing a problem).
 
Additional Notes: Rated XMP frequency & stability depends on MB & CPU capability.
 

Thanks for the reply, Bob.
 
I couldn't get 3600 or 3467 to work at all.  I cannot select a CMD rate of 3 as the BIOS only allows 1 or 2.  I would like to get to at least 2667 MHz with these DIMMs as that is the baseline for the Z390 chipset on the board rather than the 2133 MHz it is currently running.  I have always hesitated messing with the memory timings because there are so many of them.  Can I just set the main ones (like the 19-20-20-40) and the CMD Rate and let the other ones all be "Auto" and have any luck at all?
 
At this point, I'm thinking a nice set of 64 GB (4x16GB) running at 3200 would be quite good enough for me.  Quad sets are kind of pricey though. :(  How about getting two identical sets of 32GB (2x16GB) and hoping for the best on them working ok together?

You should try setting your vsa and vccio voltages to 1.35v.

According to the link below it's Hynix c-die / CJR, I think that's a fairly high bin for those on a dual rank 16gb dimm, really short QVL for Z390, most people would say it's just not that great of ram overall.  I assume you bought it as a kit and it's binned as a kit.   First try bringing up SA and IO to 1.2v, then if that doesn't work drop the freq down to 3466, 3333 or 3200.  If you change the timings try to mimic other comparable CJR kits.

I had two kits of g.skill/hynix 2x16 3000CL16 not QVL'd for my MSI board and had to down clock them to 2666CL16 for OK stability, recently bought 2x16 4000CL19 b-die that was QVL'd by both msi and g.skill. 
 
I'd recommend taking the plunge and getting some mid range b-die, 2x16 3200CL14 or 2x16 3600CL17 or 4x8 3600CL16 that appears on the G.Skill QVL:

In theory the board has daisy chain memory layout and should do better with two dimms, but G.Skill's QVL says four work just as well.
 
If you want to just get a quad of well binned b-die and do your own tuning, the Team b-die seems to be pretty good but the pricing is up from where it was a month ago:
