Can't get a command rate of 1N on Z370 Micro ATX mobo

[Lime]

Hi, i've just upgraded my ram from a DDR4 F4-3200C16D-16GTZB to F4-3600C14D-32GTZNA, everything seems to work fine, the DRAM i have won't go into Command Rate of 1N, if i try it, it will NOT POST. Should i try what someone suggested in the HardwareCanucks forum recommended someone else and raise the voltage to make Command Rate 1N possible and by how much? These pair of RAM are not on the QVL as well on EVGA's site. Any suggestions?



F4-3200C16D-16GTZB Specs:

Capacity: 16GB (8GBx2)

Tested Speed (XMP): 3200 MT/s

Tested Latency (XMP): 16-18-18-38

Tested Voltage (XMP): 1.35V



F4-3600C14D-32GTZNA Specs:

Capacity: 32GB (16GBx2)

Tested Speed (XMP): 3600 MT/s

Tested Latency (XMP): 14-14-14-34

Tested Voltage (XMP): 1.45V



So I have:

Intel Core I7-9700k

EVGA Z370 Micro ATX

Noctua NH-D14

Nvidia GTX 1080 Ti FE


Things i've tried:

Tried to up the voltage from 1.45v to 1.5v and it didn't solve the problem.

Things i might need to try:
Changing memory timings manually rather than XMP
Changing VCCIO AND VCCSA voltages, IR_Cow & a user on reddit someone mentioned that you want to raise VCCIO to reach higher memory speeds and VCCSA to run tighter timings.

Quoted from IR_Cow:
I distinctly remembering needing to raise the SA and TX voltage for 1T to work.

From my 12900K notes I have written this if it helps for 1:1 Ratio. The more DIMMS you have, the higher the voltage you need. Also your motherboard and CPU IMC can change the voltages requirements slightly as well.

Speed / SA / TX / Command
3600 / 1.2 / 1.25 / 1T
3600 / 1.1 / 1.1 / 2T
3800 / 1.2 / 1.5 / 1T
4000 / 1.2 / 1.5 / 1T
4000 / 1.2 / 1.2 / 2T
4266 / 1.3 / 1.25 / 2T

Hi,
Post some memory timing setting you have on the evga bios.

Most boards you can use F12 with a fat32 usb stick inserted to get screen shots on to the flash drive.

I do not know what TX voltage is, I'm guessing that also represents VCCIO i assume & VSA is VCCSA?

 

[ThrashZone]

Hi,
Just upload them here

 

[looniam]

VSA (vccsa?) and VCCIO are what you're looking for in there. pretty sure @ir_cow meant TX=IO as a loose translation.

Hi,
3600 is not high enough to worry about changing voltages.

Hi,

Well, it doesn't seems to work if i set CR1T on Auto voltages on the main screen (1st image) I might have to try to tinker with it. Also, to note: my mobo only supports 2 dimms, not 4.

 

[looniam]

Thank you!

you're welcome.

not to overwhelm you but here is the data sheet for 8/9 gen intel cpu's start at :
Table 7-1. Processor Power Rail
for all the spec'ed max voltages.

Hi,

fwiw, i keep looking they doubled the density 8/16x2. i'm curious of the differences in thiaphoon burner but idk, both gskill tridents . . .

Read it, very complicated. My mind just can't comprehend all of it.

Tried Manually configuring basic timings only. Went and tried 14-14-14-34 Auto and 2N, and then 1N. No bueno.

I re-reposted new images and descriptions on what i did.

Also i looked at the values in UEFI main screen and it says 1.4v is max for normal value. I don't want to attempt it though.

Tried these values for my RAM with VSA = SA 1.2 & VCCIO = TX 1.25. Does not work. If you look above at the main screen values, its practically around 1.25v for both at 2T, guessing i might need to bump the values alot higher than expected from the quote from IR_Cow:



Now this is just guessing from what i see from the chart above, i might adjust the SA(VSA) values from 1.256V to 1.356V & TX(VCCIO) of 1.240V to 1.390V. I just look at the 2T to 1T missing voltages and tried to compensate like that. That's pretty nuts thinking. If you look at the images, and compare what i'm trying to do, you'll get it.

Going to call it quits for now unless someone else has any suggestions, i've sent emails to G.Skill, EVGA. Hoping for replies back. Thanks again guys.

Hi,
You're dreaming man
You're on an older platform with new ddr4 mostly for new platform systems starting with z490.

I already stated try 3600c16 must I again your memory controller obviously can't handle c14.

it can. just not CR1T unfortunately.
Also this site states not to go past 1.25v for both VCCSA & VCCIO when clearly on main uefi home screen it shows about 1.25v's for both VSA & VCCIO almost.
I was reading other forum post seeing if adjusting those values higher might help and it states normal it up to 1.4v which seems about correct.

Hi,
All these settings look wonky, cke not as much but the others are a lot lower than what I'd expect
RFC & refi should be a lot higher

Thanks for uploading

Mostly refi is way to low

Hold up, i think that was from the default timings i had printed out from my phone. I screenshot it with default Auto settings then use XMP and restart and it shows different values with Auto & XMP.

Doesn't really matter much since i just leave it on Auto for DRAM settings and wasn't using XMP because i had just reset CMOS battery to clear my UEFI settings or i wouldn't be able to get my system to POST and don't want to touch it since i do not know where to go with the second and third timings since i've tried to just copy the settings and it wouldn't POST again.

RFC = 631 was set automatically. I never even touched that value. Thank you for suggestions.

Hi,
REFI on default should be some where near 65000 lol
And yes default rfc should be around 600

WR so-so is in the ball park

Clear cmos bios could be buggy by this time

Hi, I've re-re-reuploaded it as clearer images. I messed up by screenshotting default Auto'd RAM settings @ 2133 MHZ setting rather than the XMP profile settings for DRAM

Hi,
Well training just isn't allowing n1 thus won't post using it.

That's why I posted a asus board workaround which apparently won't work on evga because it has no xmp profile 2 which alters secondary timings

1T works or it doesn't.
basically nothing can be done about it. i wouldn't bother wasting any more time to "maybe" get it halfway functional.

 

[ThrashZone]

^^This^^
Just explore the 2T rabbit hole towards 4400 with 4400c16 as your friend funny likely on the same memory you have just 3600c16 using 2x8gb of a 4x8gb kit

 

[eidairaman1]

Set XMP, then adjust, not all motherboards can do 1T stabily, Micro ATX get short end of stick.

 

[ir_cow]

@Lime Op your post before was for getting 1T on 12900K not a 9700K.... Those voltages here will not help.

Don't quote me for a completely different setup please.

The 9th gen only has SA and VCCIO. Not VCCIO2 (11th) or TX, IMC and SA (12th gen)...

Oh okay. Its different... hmm. Well my RAM kit works just not how I want it to thats all. Im still happy. Im extremely picky about latency. I ran out of RAM opening many tabs of YT and playing games doesn't hit 16GBs. 32GB was a great upgrade for me.i needed it

I looked into ASRock Timing Configurator

 

[eidairaman1]

Understand that all hardware has a limit, eg, my AM3+ Signature Rig will not do CAS 9 at 2400 MHz for 16GB, if I try it just causes half of the ram to be useable, CAS 10 is the lowest I can Go, 1T. The Ry7 5800, AsRock B550 Steel Legend, with Micron Crucial Ballistix Gaming 32GB 3600 ram runs at XMP with cas of 16 1T.

Sometimes a setting may be too low that it causes instability, as you saw above.

Rather be stable than crash and wonder why.

yes but i'm hopeful and still exploring hoping to get it to work possibly.
