Why can't these DDR4 3600 cl14 do 1T command rate? (Alderlake 12900k)

ameek · Dec 11, 2021

Asus rog strix z690-gaming A DDR4 motherboard, and the ram that I purchased were these:

https://www.corsair.com/ca/en/Categories/Products/Memory/Vengeance-PRO-RGB-Black/p/CMW16GX4M2Z3600C14#tab-tech-specs

Memory Size
16GB (2 x 8GB)

Tested Latency
14-16-16-36

Tested Voltage
1.45

Tested Speed
3600

Now these ram work perfectly at 14-16-16-36 @ 1.45 volts, 3600mhz, gear 1:1 mode, 2T.

If I set the 2T to 1T I get BSOD's pretty quick once loaded into Windows 11 and sometimes the comp won't even load into the operating system. Why is this? Am I gonna see fps decrease in Battlefield 2042 because of this (or in games)? What's the point of me getting CL14 if I gotta be stuck using command rate 2T? I should have just gotten 32 gigs 3600mhz CL16 ram instead?

SIGH!
Any input/help/suggestions would be appreciated, thanks in advance.

I might try it with my ram. Just playing around tonight. 3800 16/16/16/36 seemingly is at 1T. My ram type is in specs over there<----

ameek · Dec 12, 2021

hmmmm, would it even effect fps in games like Battlefield 2042? 2T vs 1T. I would imagine gear 1 mode to gear 2 mode would effect fps negatively (allot more).

DR4G00N · Dec 12, 2021

Realistically the difference between 1T & 2T is nothing outside of benchmarking, just use whichever is more stable.

Modern Intel systems see hardly any difference with memory speeds for daily use so simply pick something that works and go with that.

Right but I saw the difference in fps when I had my old ddr4 3000, cas15, 1T, gear mode 1:1

VERSUS

non xmp ddr4 2133 mode (with the same ram)

The difference was I would drop down to 65 fps in Battlefield 2042 in breakthrough mode, with intense action (non xmp mode ddr4 2133). Then it would go up to 75-80 if I set the ram do it's xmp desired profile (ddr4 3000 cas15).

Now that I got ddr4 3600, cas14, gear mode 1:1, 2T = I get like 100+ fps all the time in areas where I used to get 65-75fps. All of this is making me wonder if 2T to 1T would further bump up my fps.

i have tested 4x16GB (dual rank hynix dimms) at 3600 CL16 with gear 1 and 1T CR (even at stock 1.05V VCCSA)

i'd say it's a bios issue (just look at gigabyte... they are barely able to post with 3200Mb/s XMP kits)

Damn you are right, THANKS INTERNET FRIEND. I just looked and notice there was a new bios that came out this month. It improves:

ROG STRIX Z690-A GAMING WIFI D4 BIOS 0807
"1.Improve System Performance and stability
2.Improve device compatibility.
3.Support Legacy Game Compatibility Mode to fix DRM (Digital Rights Management) issue.
4.Improve DRAM stability
5.Update CPU microcode
6.Fix Intel VMD issue

Now my ram can do 1T, gear 1 more, 3600mhz cas14.... and I notice my cpu clocks higher to without any OC (before with the old bios it would only go up to 4888mhz, now it goes to 5.0ghz)

Installed this bios on my board today too, but not fiddled with anything yet

I have never managed to get 1T working on intel for over a decade outside of massively underclocking, you will gain far more from tuning secondary and tertiary timings.

Don't think n1 and mode 1 work together unless you use xmp 2.

Hi,
Think you exceeded the cpu's memory controllers abilities

Think you should try manual mem oc and switch to 3600c16 and tested latency timings 16-16-16-36 at 1.35v.
You should be able to switch cl to c14 in secondary timings but I've never used a evga board so I have no idea what bios timing options are available.

I don't do Tom's website anymore to much crap adverts/ player...

You might also make a new thread seeing you're not using the same as the original poster has.

Hi,
You have a much better kit with 3600c14 then the typical garbage 3200c16 people buy because it's cheap.

You just need to adjust the timings so the controller isn't overworked.

ir_cow · Mar 17, 2022

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

I don't care what ICs are used, that is too much voltage unless you planning on a one and done deal. OC to hell, set a record and throw the memory away.

4000c12 though, nice but not at 1.98. Mine are teamgroup B die, imo they are good ram.

You must have special memory that supports 1T and it has nothing to do with Intel.
With my current computer I ordered DDR3 1600MHz 8-8-8-24 but what I got was DDR3 1600MHz 9-9-9-24 but I was able to run that memory in 1T command rate.
So my question to you or anyone really is what is faster?
DDR3 1600MHz 8-8-8-24 in 2T command rate or DDR3 1600MHz 9-9-9-24 in 1T command rate?
