Added images from the dram calc and highlighted the values i'm not certain of their locations / which entry to edit.

I think Vref is fine at auto since it's just meant to be 0.5x the full DRAM voltage.
CLDO VDDG is on the main "Extreme Tweaker" page right below the DRAM voltage.
I assume the CAD_BUS timings are entered directly above the cad bus block termination???
4x8GB on C6H here. I couldn't get any combination of the calculator to work for 3600, ended up sort of tweaking a 3866 set of timings.

Use the CLDO VDDP and CLDO VDDG voltages in the AMD Overclocking menu.

cluster edge Hello, guys!
Recently I've upgraded to 3800x on CHVii and managed to get [email protected] preset. But AIDA readings telling me that something is definitely wrong:

https://ibb.co/kJ8ZnLm
https://ibb.co/4N5MRGP
All settings are set from the latest version of Ryzen calculator (Great kudos to @1usmus !)

Earlier on 2700x CPU 3200CL14
https://ibb.co/74MSjpP

Any thoughts will be appreciated!

PS Images linking with preview doesn't works fine for me, so only links(

Solohuman So I ran Thaipoon burner again on my rig & it produces a '?' in the readout from part number section. That is it went like this > H5AN8G8N?FR-TFC.
But I still went with the option of CJR for my Hynix chips.
Entered the values for 3533MHz (board only supports up to 3466) rebooted & ran memtest86+ v8.2 for 3 passes & all successful!
Now doing windows memtesting.

Hey,


SoC was on Auto but it seems to already be at 1.1V and not sure if i should push it further. I set VDDP to 950mV and VDDG to 1000mV after the random rebooting, not sure if that helps much tho. Worked for the rest of the evening but i wasnt afk that much to really test it.

Solohuman @LicSquato & thomasck

Thanks, I understand now, they should make that part clearer when reading Thaipoon burner readout imo.

Any help is appreciated!





System:

3800x
Aorus Master
2x 16GB Samsung B-Die DR (16 16 16 36 3600Mhz -> OC to 3800Mhz with help of DRAM-Calculator)
Not enough SoC voltage get it up or increse LLC of SoC

Also, be careful that the timings may not be in the same order as those shown in BIOS.

herericc Just put a 3900x in my Crosshair VI hero with 4 sticks of 8GB TeamGroup 3200MT C14 samsung ram.

V1 of DRAM calc's 3600MT settings don't work for me - they boot to windows but I can't get past 5 seconds of DRAM Mem checker without tens of errors. What's my next step? Try V2? then start bringing in timings one at a time?
?

I'm running the latest (official 7306) bios from the C6H support page. There's a newer one (7401) but it's unvalidated which is kinda sketchy - it's on a dropbox, not their official site.
