VRM Temps

[Big Head Tech]

Just picked up a Gigabyt AX370 Gaming K5. My 5th motherboard for my build (keep switching out). I've come to realize that 16gb dimms won't go past 2400MHz on Ryzen. 5 boards 3 sets of ram no luck.

 

Anywho, the VRMs are hitting low 90s under stress test. My settings are as follows.

Ryzen 7 1700 @ 3.8GHz

1.4V Core

1.05V SOC

 

Ram @ 2400MHz

1.35V

CL15

 

I'd like to hope that the VRMs are good to 125*C but not 100% sure.

1.4V is a little on the higher side for Ryzen if I'm not mistaken and well at 90C if that is on an artificial stress test that isn't unwarranted. It's still safe but for sure on the warm side of things I would try to see if you can lower the voltage a little or ensure good airflow over the VRM heatsinks.

That sounds high.  What kind of wattage is your CPU pulling?

Going to test 1.35V and see if it is stable.  Core temps are mid 60's though.

95-105W

Hahaha.

K5 has really trashy VRM. Too bad everyone ignores my guides.

1.4V R7 will fry them, could happen within 2 years, maybe even 1.

Mosfets are fine.

Capacitors are not

How are you measuring those temps?

I backed it down to 1.35V @ 3.7GHz.

Just read over your guide and while its okay, the x370 Prime from Asus is absolute garbage.  Had 3 of them, tons of issues.

Board sensor.

A VRM setup that can't handle 105w is completely rediculous.

During gaming my VRM's are in the low 60's so I should be good at 1.35V.

Prime B350 Plus has way better VRM.

Dont know how about other features.

60°C should be fine

tbh id lower the vcore. a cpu like the 1700 is very good and will likely last you for several years. 1.4 wont kill it but youre likely sapping a few years from it

Expected Gigabyte VRMs run hot even their top in board loses to ASUS and Asrock hell even MSI titanium which yeah i know the Titanium is much more expensive but everyone knows MSI uses crappy NIKO. 

 

90C is fine under stress however also 1.425V is fine according to Robert Hallock from Amd. Don't worry about it i bet by the time the CPU starts to die you wouldn't want it any longer anyways meaning it would take 7-10 years before anything bad happens.

PS: Asus Prime X370 Pro has way way way better VRM. Super efficient and very powerful for $150

The amount of headaches I had with 3 of those boards was not worth it. I even had one that wouldn't boot with a Ryzen 3 or 5 installed. Had one that wouldn't overclock if I changed the multiplier it got stuck at 1.5GHz. Lastly I had one that wouldn't boot with 32gb of ram. It's probably a good board but had issues like no tomorrow.

1.5GHz bug is on everything.

32 gigs is generally shit combination for Ryzen
