Has anyone had success overclocking 4 ECC DIMMs beyond 3200 mhz on the Taichi x570?.
I’m using 4 x Samsung DDR4-2666 ECC UDIMM PC4-21300V-E Dual Rank x8 (M391A2K43BB1-CTD-MDN). The DRAM calc by 1usmus outputs super tight timings like CAS 14 for 3600mhz. Which never posts. I’ve been able to hit 3200Mhz with 1.356v and timings set to 17-17-17-40 (CL-RCD-RP-RAS) / 57-433-322-198-7-4-26 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-FAW). Anything not listed is on auto.
No Errors in Memtest86+ or DRAM calc’s ram test.
Notes:
-
BIOS is latest 2.7 released 12/09/19

3333mhz will post with same settings, haven’t stress tested it. 3400+ no post. Have gone up to cas 22 with 1.4v and 1.125v SOC, but no post. Not sure that voltages beyond that are safe for 24x7.

I don’t think power delivery or cooling are factors , I’m using…
CPU: 3900x
PSU: EVGA 850 G+
Cooling: Custom loop CPU/GPU same loop. 2x420mm rads with 3 Riing 14 fans on each. Good overall airflow, memory sticks are cool to the touch on working 3200 settings
