Latest beta bioses

• 1001 (DRAM 1T mode) Restore defaults before flashing, or use USB BIOS Flashback.
  
• 0038 (DRAM 2T mode) Same as 1001 but DRAM set to 2T mode, better on some systems.
  
• 0902 First viable bios for C6H. Superseded by 1001 & 0038.

Wait,it can go higher than 3200?Wot,same voltage(1.35)?

No problem also, 3466 CL14 @ 1.37V

Heh, nice.
You got it a bit more efficient.

I had to up the voltage of RAM from 1.35V to 1.4V to be able to boot 3466MHz, but I didnt even try anything between the voltage (like 1.37)
It wouldnt like any higher, so I didnt really bother much yet.

I see few differences in timings (although you have a different model), I didnt really tweak those from my default XMP 3200 yet. I only overridden the auto settings with the ones found in SPD XMP along with applying D.O.C.P.

Gotta tweak moar xD

Got 3466c14 stable.



Had to up vcore from 1.375 to 1.400 at 3.8ghz cpu.

It doesn't work for me either... 😞 It say "UserInfo.ini not found!"

Anyhow, here is my final memory settings tweakit report and score:
Rock stable, checked with HCI memtest, MemTest64, Prime95, BOINC, several games...

Hi Guys,

I haven't tried to OC my dram for a long time since initial fails after I purchased it back in may. Now with the new bios update I was able to get it to work semi-stable at 3200 mhz on Stilt's Safe 3200 1.4v 14cl preset (the only issue I am having is that sometimes (not always) DRAM will not post after a cold boot, and will start with 2133 mhz, but bios settings still show that 3200 is selected, so I have to change it to auto - restart; then change it to 3200 again and restart, and that returns the dram to 3200mhz until another no-post and 2133 reset in a few days).

Can I get these sticks to run stable at 3333 or 3466? I am seeing drastic in-game fps increase with 3200 compared to 2133 (like 20+ min fps increase in the game I play - Battlerite), so I would like to see if it can be increased even higher with higher dram frequency.

I would appreciate any advice either regarding how to get my 3200 more stable, or maybe somebody could share their experience with maing this dram run at higher then stock 3200 speeds.

My set up, if this matter: C6H, Ryzen 5 1600 with x37 OC to 3700 mhz, G.SKILL TridentZ RGB Series (2 x 8GB) 288-Pin 3200 14cl F4-3200C14D-16GTZR, Strix RX580 8gb, TT 750 watt gold PSU.

Thanks!

Basically, RAM that you have is same as mine, single rank Samsung b-die, rated 3200CL14. Cold boot experienced is common for many users when set to 3200MHz or higher - to blame are ASUS and AMD. There are some partial workarounds but not a final solution, you can read in other threads on this forum, like here:
https://rog.asus.com/forum/showthread.php?97184-ROG-CROSSHAIR-VI-HERO-Cold-boot&p=684401&viewfull=1#...

Anyway, Ryzen is responding very well to increased memory speed since its internal "Infinity Fabric" is running in sync with memory. From my experiance and from what I seen on overclock.net forum, I have no doubt that any single rank Samsung b-die can run stable at 3333MHz CL14 at 1.35V. Often 3466MHz is also possible and stable at around 1.40V but it sometimes require a bit of luck and patience in finetuning few IMC and memory parameters to have it 100% stable.

Thanks for the response! What frequency do you have your dram set to (and settings - do you use preset or have em entered manually?)? Also, do you know if setting fail count to 3-4 might help with cold boot issues, or is there something internally wrong, and no matter how many fail counts you set the dram will not post until reset to 2133?

I am also wondering why silt's safe settings for 3200 dram run it at 1.4v if everybody seem to agree that 1.35 is more then enough? I've been running it on 1.4v for a month or so now, and the temps while gaming are around 45C (I do have a huge case, TT View 31, with 6 intake case fans in the front and bottom and 3 exhaust fans on top and back). Do you know if 3333 or 3466 is "safe" for our kits to be a 24/7 regular gaming setup? I could care less about bench performance, but that FPS gain on higher DRAM speeds is just insane on my ryzen system...


Edit: Also, there is a pretty good post about OCing similar Samsung single side B-die 3200 cl 14 Flare X sticks to 3446 and beyond, (https://rog.asus.com/forum/showthread.php?93722-Flare-X-3200MHZ-16GB-2x8-F4-3200C14D-16GFX-Performan...) - Do you think this giude should work on my trident z rgb as well (it is my understanding that architecture wise the flare X and TridenZ should be very similar, if not identical?)?
