New Ryzen 5 1600 build and some questions!

post #1 of 19
Thread Starter 
I just recently upgraded my 9 year old core i7 920 and oh man does it feel fantastic!!


old system
CPU - 1st gen core i7 920 @3.7ghz
Cooler - Xigmatek Dark knight
MB - Intel DX58SO
Ram - 6gb G.Skill 1600mhz triple channel ddr3 9-9-9-24 1.66v
GPU - XFX radeon HD7770
PSU - Silverstone Decathlon 850w
HDD - 640gb WDC Black

New System
CPU - Ryzen 5 1600 @3.8ghz 1.29v-1.319v
Cooler - Amd Wraith Spire
MB - Asus Prime B350-Plus
Ram - 16gb G.Skill Flare- X 2400mhz Dual channel 16-16-16-39 1.2v
GPU - XFX Radeon RX480 8gb 1320mhz/2120mhz
PSU - Silverstone Decathlon 850w
SSD - Samsung 850 Evo 250gb
HDD - 640gb WDC black

Night and day difference between these two systems, the ryzen system is just...... oh so sweet and the intel system.... well, lets just say i give intel an A++ for longevity, but ADIOS!!! Good Riddance!! Intel will not be missed...


I'm still in the process of getting everything stable and playing with the overclocks, But I do have some questions if anyone is capable of answering them, that'd be great!



#1 - With every single setting in the bios set to auto aka Optimal Defaults, cpu voltage ranges from 0.4volts to spikes in the 1.47volt range, Even with EPU power setting enabled volts still jump to over 1.4volts even at idle.. i can run 3.9ghz while keeping every voltage set to auto, sure the temps do not reach over 60ºc EVER!!! but the high voltage just ..... well, I dont like it...

My current solution is to run at 3.8ghz with a slight voltage offset of +.05000 this makes my voltage range from 0.4v to 1.297volts with some spikes hitting 1.306volts I do not know why the voltages spike so high and so often with everything set to amd's default settings, but if the voltages are legit(reported by 4 different pieces of software including the bios) then even with everything set to auto my warranty is being voided by these voltages?!?!?!

#2 - I also have some issues understanding what some of the bios settings are and what the optimal settings for them should be since i am trying to keep my cpu at around 3.8-3.9ghz stable 24/7. my previous intel board was very difficult to overclock, this one seems easier but has a lot more settings

VDDCR CPU Power Phase Control -Optimized/extreme
VDDCR CPU Switching Frequency 200khz-350khz
VDDCR CPU Load Line Calibration - auto,regular, medium, high, extreme
VDDCR SOC Load Line Calibration - auto, regular, high, extreme
What is SOC? I've heard increasing it's voltage can increase stability?

# - 3 On my previous 1st gen i7, it took me months to get my 1600mhz rated ram to actually run at 1600mhz but once i finally did, i was able to overclock my 1600mhz ram to almost 1800mhz though i never really kept it there for long. With this new ryzen system, the 2400mhz rated ram runs at 2400mhz right out of the box, even without the memory profile, but any type of increase in memory speed will not post, anyone have suggestions on how to maybe get my 2400mhz ram to run at 2666mhz? or do we not think this is going to be possible at all, ever on a ryzen system?


thanks guys!!

Is this trolling or something, i think you are unintentionally playing with fire. Immediately set everything back to default before the new PC dies, which is, i would say, is pretty inevitable. You should give Intel an S+++ for creating incredible fool proof designs and will discover just how little of that AMD has in store. Although my bet is, that samsung 850 evo will die first(the only sensible thing you "upgraded" to btw)

I just wanted to point out it's a Ryzen 5 1600 at 3.8GHz. Nothing to be overly alarmed about even with 4 phases with doubled low side mosfets if they're cooled properly. That's going to draw less than 70A likely.

While the B350 Prime Pro isn't superb the 70A load distributed among 4 phases for high side and 4 phases with 2 mosfets per low side is going to be only 18A per phase.
The two 4C06N mosfets per low side can handle that , it halves the effective RDS(on).
Conduction Power loss for low side = (I_D)^2*RDS(on) * duty cycle = (18)^2*(6.0 mΩ * 1 phase/2 mosfets)* (1-(1.3V/12V)) = 0.86W power dissipation per low side mosfet
High side loss for 4C09N based off f_sw = 300khz would be :
0.5*V_in* I_out* (f_sw)*(t_r+t_f) = 0.5*12V*18A*300kHZ *(32ns+6ns)
= 0.5*12V*18A*(3*10^5 Hz)*(38*10^(-9))
~~ 1.3 watts switching loss at high side @ 18A per phase

for the max switching frequency allowed on the board, f_sw = 350KHz , you get ~ 1.4W ----> without a heatsink this would easily hit 90°C based on the RΘJA = 50 °C/W but it does have a heatsink and RΘJC = 4°C/W

The maximum continuous current for the 4C06N low side @ 80°C is 14.9A and it's running two of them.

Total is about 9W of power loss for 4 phases.

@ Meintool , What are your VRM temperatures?

Unless you received a dud chip your CPU should be able to get 3.8 - 3.9GHz @ 1.25V.

Interesting stuff, going to take a bit of time and try to understand these calcs.

there's a typo which I fixed , 32+6 is 38 not 40
:S

It's the same result due to rounding but just a FYI

some good reading on https://www.fairchildsemi.com/application-notes/AN/AN-6005.pdf

(I have the excel file if you need it)

I'm less concerned about the mainboard and more about how freely OP plays with voltages and general system components. I looked up his post history and OP was complaining about suddenly getting 80°C @idle with his reference (..) rx480 a week ago, doesn't look good for case temperatures, and then suddenly stopped posting so the worst might already has happened.

How do you feel about the B350 Gaming from AR?
