Hehe, for me its just a question of seeing how far I can push it. I will probably go back to 3200 CL14 when I am done unless I can get decent timings higher. I don't game much so I am not worried about RAM speeds. Most of what I do is 3d rendering, sculpting and modeling so the differences for my particular use case are minimal to non existent. I am an overclocker at heart however so I just can't resist it Tongue

For quite a while I had the highest clocked stable RAM for a Ryzen system with my 3533 validation, that was fun but took about 2 weeks of messing about (before the calculator). I got 3600 to boot into OS but it was not 100% stable. My kit is 3600 @CL18 (XMP) so not the tightest timings for the frequency. I believe it was one of the early "ultra fast" DDR4 kits, complete active cooling solution. I am glad I got it when I did, now for a comparable 16gb 3200 kit I would be paying just as much and this kit was leagues more expensive than it's nearest price competitor. I honestly can't believe how much the prices have been gauged. I have not seen RAM prices skyrocket like this since the factory fire in 2013.

xalter mindblank done a good video on youtube comparing the cl14 low latency 3466 very low latency and 3600 at xmp in games

the 3200 low latency beat the 3600 stock in every way

i didnt even try 3600 with my kit as i doubt i could get cl14 primary so settled on the 3466 cl14
i still need to tweak them this weekend

Will be giving this a shot myself on my 3600 kit. Best I managed was 3533 but had cold boot issues. My timings were pretty loose though, performance is actually better at 3200 for me than my 3533 settings were. It would be nice to get my full 3600 or more out of my rather expensive kit Big smile

a quick brief guide
run thiaphoon
click read/dump thingie
scroll to the bottom click show timimgs in nano seconds
enter these into the fields of calculator
make sure you also change the drop down to either 1/2/4 sticks of ram and either single sided or double sided and the brand of the memory chips eg samsung or hynix
then press any or the choices eg safe/fast/extreme

any mistakes above will result in wrong suggestions

it should work no problem on safe and pretty high 90% fast chance
my old 3200cl15 used to run at 3333cl14 no problem on fast suggestions

The Dram tool has an option to read the XMP and from there you can choose the frequency you want and then you have 3 options for calculation: safe settings, fast settings or ?žextreme??forumCodes=True

nvm i managed to source hte vidoe showing thaiphoon utility which is a complete dump of the dimms,

though the recommended settings are no way ever going to be stable lol. I was recommended lower timings than the XMP stock profile on my dimms are specified for but hey I gave it a shot.

i too use the ryzen ram calculator its been a blessing to me

but ive also learnt to enter every single suggestion and setting
even these cad bus block etc cldo voltages everything

it may well be a bios issue not having enough brains to iron out the flaws and issues as it has to make/try some settings itself based on what your xmp asks for or you manually enter

not trying to rub salt in the wound but i got 3433 cl14 first try with the new tridentz 3866 ram this weekend on mine ,


where would you be able to pull the Memory type or the values required to generate the rest of the fields. utilities like cpu z are limited and bios just shows the current timings i believe unless i missed a menu

Waaait what ... my system just booted up ... cold. OK it wasn't unplugged completely but it was turned off for several hours.

And no, I didn't reset the CBS RAM settings. Last thing I did yesterday was typing in the basic part of the DRAM calculator settings I had. I just left the "Interleaving" part alone since this seems to not work for me, at least it causes the system to fail the last time I tried it.

Now I had to try shut down and unplug the system, just to be sore. But unplugging again gave me a cold boot fail. Now I typed in the exact same settings as before and also tried to OC a littel, set the RAM to 1633 Mhz, not too much but at least something.
Windows booted and runs fine at the moment. We'll see if it will reboot tomorrow.

However I still got NO idea what's different this time.

I don?™t think this is the problem because I had regular SATA SSD before and had the same issues and it works as soon as the RAM is set to recovery defaults so...

But I will check the nVME FW just to be sure! Thanks for the hint!

[URL=][/URL]OK guys ...

I posted and tested alot here, I was trying to help finding new and testing old bugs and I thnink I also posted my specs but if not I'm sorry!

I tested to keep my PC plugged to the wall but unfortunately it didn't help. It feels like there's capacitor that runs down and causing the issue on reboot. Why? Because when I turn of and on within a short time it's OK but if the system is of over night for example it would not boot.

The System runs FLAWLESS with all the Settings I ever tired, I ran Memtest tu ensure my RAM settigns are stable. I played AC Origins for hours and also ran 3D Mark with this settings without any Problem. I know how an instable system behaves, especially with bad RAM but this doesn't look anything like that. Which doesn't mean it couldn't be a problem with the RAM settings, maybe an option/seting that causes this problem but I am not aware of... I'm new to this CBS stuf and the way these OC Settings work is really wired and not intuitive to me so probably there's a eror I just missed all the time.

Here's my full spec:
Board: Fatal1ty AB350 Gaming-ITX/ac
CPU: Ryzen 5 2400G
RAM: G-Skill 4000 C19 16GB Kit (Samsung B Die)
Drive 0: Samsung 960 EVO 500 GB nVME SSD (M2)
Drive 1 Samsung 840 128 GB SATA SSD
Case: Silverstone Raven RVZ03 (LED and 2 Fans connected)
Cooler: Noctua <span ="st">NH-L9x65 AM4

Display is curently my 47" Philips LCD TV over HDMI.

OS: Windows 10 Professional (latest build, all Updates)
Drivers are used from Windows except Chipset and GPU, those I downloaded from AMD and installed in the correct order (first Chipset then GPU).

So far everything works fine except the throttling issue in games, so I runed of the Turbo in CBS.

Here's my UEFI Settigns:
First, I did a cmos clear by Jumper (have no button).
I changed the configuration to CBS and set the DDR Voltage to 1.4 V
In CBS I set GFX mode to forced and specified Framebuffer > 2G
In the DDR settings I set Command Rate ot 2T
I set Frequency to 1600 Mhz
Timings: Top down - 14/14/14/14/24/48 everything else on AUTO

This was tested as I said above and it worked. I also tried setting these over AMD Ryen Master and it also worked.

I aldo don't understand why ASRock doesn't support to enter these values as simple decimal numbers instead of HEX which can also cause errors ...?!

However, now you should have all the informations, maybe there's a solution???

You're Problem May not be memory related at all. Are you running the latest firmware for that Samsung NVME Drive? Research Samsung NVME boot issues.
