GSkill & EVGA & Z390FTW
 

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

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)

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 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?

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?

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:

Yeah, nothing worked and even get to POST.  I had an evening of drinking Gin Rickeys and contorting to clear the CMOS every couple of minutes.
It was a 2x16gb kit so they are a matched pair, supposedly.
I'm going to have to get some better memory to bump up the speed of it apparently.  The Sniper X memory 16GB modules do not agree with the Z390 FTW at any speed I tried above 2133.   I put the VSA and VCCIO up to 1.35v at 3600 and 3200.  No dice.  I left the memory timings on auto and set the frequency to 2667 and 2400 w/o luck.  It runs fine at 2133, so I'll leave it there for now.  I may look at some of the other Sniper X timings that are certified for 2667 perhaps and try to apply them directly, and try the highest 1.2v rated timing (is that 2667?).

Oh wow that's horrid.  Just give up and get some 2x16 3200CL14 b-die, it's compatible with everything and the cpu will bench about 10-20% better than what you have now.

Except now I'm buzzed a bit. :)  If not for the $400+ cost of the CL14 3200 MHz b-die parts, I'd have them on the way via prime or newegg.  Not gonna drunk shop though.  It can wait until the morrow.  I just hope it's not the mobo itself having a problem with the memory channels going full speed.  But if so, EVGA has been kind to me in the past.

Ohhhh yeah I missed you're wanting 64gb.  Meh.  Two 32gb kits combined are not going to run stable on straight XMP, imho get a 64gb kit.  Pretty limited QVL on those:

The Flare-X kit was $480 up until it went out of stock a couple weeks ago:

The ripjaws and trident kits were in the $500's and haven't been in stock for a while.
 
Unless you REALLY need 64gb, the Trident Z 32GB kit for $240 is reasonable, though other versions have been less.

Yeah, *want* 64gb.  I really don't need it.  32gb will be fine.  But the G.Skill Trident Z kit at the top of the list doesn't actually exist on Newegg.  The current part (https://www.newegg.com/p/N82E16820232378?Description=F4-3200C14D-32GTZSK&cm_re=F4-3200C14D-32GTZSK-_-20-232-378-_-Product) is $320 and is not sold by Newegg but one of their partners from Asia.  And I really really don't want RGB.  It's a clean, quiet build.  But I could get the Trident Z RGB version on Amazon for $260. Hmmm.

It just went OOS. The desirable b-die goes in and out of stock constantly.  They load new stock throughout the work day, pacific time.  I had to wait a couple weeks for the trident Z kit of 2x16 4000CL19 that I wanted.  
 
The Ripjaws kit should normally be about $220 and the white/silver Z kit $230.  Flare X $215.  Just check this search a couple times a day and be patient:

Hard luck ! As many memory makers (or some of their kits) aren't listed on the QVL list of motherboards vendors because it's simply impossible for EVGA or other companies to test each type of memory since they are too numerous... Maybe the best is to sell your current 4x8Gb Gskill kit to buy another one, i've got the same motherboard as you and the same cpu for one year and my Ballistix Elite isn't listed on the QVL list neither and i never encountered any problem at all to make them work at their xmp profile and even overclock them without increasing their voltage...

Ballistix Elite is high binned Micron E-die, their bins may be somewhat conservative too, it is newish but developing a very good reputation.  Expensive.  Not surprised to hear it works well for you.

Buying antother memory kit most likely won't help. The imc on your cpu is most likely weak, and the only way to correct that is to get another cpu with a stronger imc. Gotta love silicon lottery. Did you also try running your ram at 1.35v along with the vsa and vccio at 1.35v?
 

If you're not able to run higher than 2133 with another set of ram then I would highly suggest rma'ing the cpu as you should be able to run 2666MHz without any issues at all.

DRSpalding
Yes, I did.  And I hope you're wrong about the CPU. :(  I'm more hopeful that the memory is either not actually matched or that one or both are simply not up to the task of being run at faster than 2133.  Since this RAM was the budget buy part of the build, that seems to be more likely.  Also, a teachable moment for me.  I need to read the specs better and pay attention beyond the "Ooooh, ahhhh, that's 3600 MHz.  And it's cheap!"  Cheap for sure.  But no bargain.


If it is the case that a quality set of 2x16gb CL14 3200 DIMMs don't work any better, I will likely at least be able to run with 64GB at 2133MHz.

These happened to pop up as a price reduction on my newegg wish list, they are 2x8 4000CL19 b-die with nice tight timings, for $112 a set.  You would almost definitely need to clock them yourself, but they are a good value, two sets for 4x8 at $224.

I just purchased a set of 2x16GB Ripjaws that came back in stock this morning on Newegg: F4-3200C14D-32GVK.  We'll see if my CPU can deal with the faster memory or if I have to try to RMA a 1+ year old cpu with Newegg, as I built this in machine late 2018.

Great kit, hopefully it works!!

I received the memory today after a couple of days of delays due to the snow here in WA.  I plugged it in just now, went for broke and enabled the XMP Profile #1 at 3200MHz, and put VSA and VCCIO at 1.2v and she goes!  👍

kevinc313
 
Hey that's great.  The b-die is really great memory even in a midrange bin like 3200CL14.  That bin is also compatible with almost everything and should be really stable.  You should see some major improvement in benchmarks, coming from 2166.
 
My 4000CL19 has been running really well over the past few weeks.
 
May want to try the SA/IO on auto and see where the XMP profile makes it set to.  Mine puts them over 1.3v on the new kit which was much higher than my old kit, so I've just left it like that for now.

I looked at them in the auto setting and after having read that the chipset tended to overvolt the VSA and VCCIO a bit, I went with 1.2v explicitly.  The VSA was around 1.25 or more in auto mode and the VCCIO was 1.2v.  It runs ok so far with them both explicitly pinned to 1.2v.
