x370 Taichi OC limit and Boot stability

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi.
This is my new build:

Ryzen 7 1800X
X370 Taichi
32 GB G.Skill FlareX 3200mhz (8GB x 4)
Samsung 960 m.2 ultra nvme
* I'm using my old Thermalright Macho Rev.A for cooling.

Graphic Card: ASUS GTX1060 Dual OC 6GB (stock factory OC only)

And I can't OC over 3.9Ghz. Anything above that crash and restart the PC in prime95.

My sets are:

Overclock Mode - Manual
APU/PCIE Freq Mhz - 100

CPU Freq and voltage change - Manual
CPU Frequency (Mhz) - 3900
CPU Voltage (V) - 1.37500
SMT - Enabled

DRAM Timing Config
XMP 2.0 Profile 1: DDR4-3200 14-14-14-34 1.35V

AM4 Advanced Boot Training - Auto

Voltage Mode - Stable Mode

CPU Vcore Voltage - Fixed Mode
Fixed Voltage (V) - 1.37500
CPU Load-Line Calibration - Level 1
Fixed Voltage - 1.08750
VDDCR_SOC Load-Line Calibration - Auto
CPU OVP - Disabled
CPU OCP - Disabled
DRAM Voltage - 1.350
VTT_DDR - 0.680

VPPM (2500V) - Auto
2.5V_PROM Voltage (2.500V) - Auto
+1.8 Voltage (1.800V) - Auto
VDDP (0.920V) - Auto
1.05V_PROM Voltage (1.050V) - Auto

Cool 'n Quiet - disabled
Core Performance Boost - disabled

My personal use is Virtualization with many VMs at same time, and ocasionally some modern game.

Do I need to change something to improve? Maybe a OC over 4Ghz???

By other side, my boot time are awful. Disabling "AMD Advanced Boot Training" improves post time a lot (to ~24 seconds to reach OS Deskop), but some times boot fails, and reverts my OC settings to standart.

Is there a way to improve boot time and stability with AMD Advanced Boot Training DISABLED? (To improve boot time mantaining boot stability?)

Why "Ultra-Fast Boot" boots directly to BIOS config again only, instead of OS?

Thanx in advance.

Zatanus

	Advanced boot training should always be ON, IMO. We're far from the times of well-baked AGESA, where one wouldn't need the training. As a rule, boost SOC voltage to 1.1V (or a tad more). Also, stable 4GHz (and above) is more of a luck, rather anything else. Reviewers got binned chips, meaning the latter were pre-tested to reach the 4G-mark. My general knowledge of OC-ing Ryzens is still limited, however. Maybe someone else here will help you reach the 4G. Just think is it worth it, though. 100MHz more for way more heat and stress.

	well for starters why the frack would you disable cpu over current and over volt protection ? this is a very very silly setting to change as said 3.9 seems easy 4ghz isnt the voltage for 4ghz is also more or less always over 1.4 volts and sometimes needs quite a bit more IF ! you do get a boot at 4ghz even with 1.425 ish volts remaining stable at 4ghz is very hard to also achieve as for boot time, i have more bad news for you 4 sticks of flarex set at xmp default STILL isnt happy with amd bios settings ,this is why your boot times are taking so long the system is trying to get the ram stable in its pre boot testing this can be helped by adjusting some of the sub timings in the ram in the taichi bios and also to note the ram tweaking will probably bring more to the table than the extra 100mhz of cpu speed heres a link to the program we use to find out what settings to change for the ram http://www.overclock.net/t/1640919/ryzen-dram-calculator-overclocking-dram its been extremely helpful with all brands of ram and also helps set more stable timings on the amd flarex branded ram

	Thanx for the responses. I was disconnected many days ... I'll try to disable AM4 ABT with lower RAM Mhz... I chose AsRock because I wanted a PC that can start fast ... but its post times are very bad with that option activated.
