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.
I have a C6H which seems to be mostly in the same order as the calc thankfully.

You only need 1.4 for 3600MT??? That seems low!

The values I'm most curious about are the CLDO VDDP and CLDO VDDG voltages - VDDP shows up in the tweaker's paradise menu, as does CLDO_VDDP. 1usmus gives values for both, but i'm not sure which is which lol.

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???

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.

Yes, now is possible! See the "Part Number" in "Dram Components" (2nd column) and you will found the "CJR" words...

SaccoSVD Usually when is apparently stable but something fails I add one more notch voltage to the RAM.

I run Thaipoon burner to get my SPD readings with my ram, it tells me I have Hynix chips but does not tell me what kind because DRAM calculator has 3 diff types of Hynix to pick from when calculating. So how does one know what type of Hynix it is?

Thanks in advance!
