Advanced Notes
For experienced users, here are some notes that may aid you
If you try to manually adjust your memory timings you will notice that at above 2666
system memory multiplier your CAS Latency timing when measured in Windows will
always go up to the next even number. For example a CAS Latency timing setting of 15
in the BIOS will show a setting of 16 in Windows.
If your settings are too aggressive you might see the two following codes on your
Diagnostic LED:
00followed by no monitor signal : Turn off your PSU for 20 seconds and
then turn it back on.
00 followed by monitor signal : It’s all good. It happens few times instead
of OC. OC followed by no monitor signal: CMOS the motherboard.
78 : Try to press the “Reset” button few times. If it doesn’t pass it again then CMOS the
motherboard.
4F : If the poster stops there eventually the motherboard will switch to the backup bios.
In order to avoid that CMOS the motherboard.
On Ryzen Threadripper the Northbridge frequency is tied to memory frequency. 3200
DDR4 frequency is 1600 DDR frequency which gives us 1600MHz of Northbridge
frequency.
Last but not least, always tighten the screws of the socket at the very end.
