VRM Basics Part 2 - LFC
HTML-код
- Опубликовано: 3 мар 2021
- In Part 2, we're going to do a basic stress test to show how low-end VRMs and higher-end VRMs behave. Phase count isn't everything! There are lots of contributors to performance, and different mobo / VRM setups have strengths and weaknesses.

According to datasheets, most modern mosfets are good for 150c. So 100-120c may well be totally fine. Not sure I'd want anything on the mobo to be at that temp, but maybe someone who's tested to destruction knows the answer there.
Did anybody else see the battery Graham on the MSI board? 😂😂 . Good video, and conclusions.
As buildzoid would say, "More phases doesn't mean good phases."
I appreciate you did not try to just sell the results you expected before the test, but indeed showed the frustration and suprise (which are typical in science) - and kept on the hustle doing the OC to at least come close to a more conclusive statement. I imagine there are ppl that in such circumstances would get their ego in the way and would not be able to admit, that their expectations proved to be "wrong". Can't highlight enough the importance of how you reacted on that and the attempt to keep a "scienitific value".
Absolutely loved these two videos! I hope we get more of these educational videos going forward. My favorite part though was you posted it even though your results didn't support the initial hypothesis. Being wrong is one of the best ways to learn things in depth.
I appreciate the amount of testing and time you dedicated to this video. Good job man! Thank you for educating all of us!

Loved this 2-part series, thank you.
Good day sir , I can’t Starch the amount of words on how much you teach us how to take apart in put back together thank you 🙏 so much
I've been struggling for years to understand motherboards and VRMs. I watch a lot of LTT and i've watched some Buildzoid videos, but the former barely talk about motherboards, and the latter goes way over my head. I've seen spreadsheets comparing motherboards & VRMs when people feel like making them, but that doesnt exist for every generation. So I wish I understood them better. The first video of this pair definitely made me feel better, but then this video flushed that all down the drain. I do appreciate all the effort here and I do feel like I have a better understanding than when I started. The drawings in part one were SUPER helpful. thank you.
Quality Content Grahamif i wasn't about 250 miles away from you - you'd be the first person id recommend for pc stuff to anyone. and not long until you get the 100k subscribers
Finally sat down and took this in.
All that time and effort did draw some useful conclusions. 1. Ryzen being what it is with FIT, plays things extremely safe; at all auto settings, even modest VRM boards will work fine. 2. The VRMs become extremely important when moving to static clocks and manual Voltages, so it's obviously of importance to those who tinker and overclock. So, the crap VRM boards are perfect for the non-tinkering layperson, and for those who do wish to overclock, VRM design becomes the item around which to base a purchase decision. Great work!
Very informative. Thank you!😊
I appreciate the vrm test comparison/troubleshooting
Can you do basics on RAM timing such as CL and such?
It was fun and it shows you actually performed an experiment, rather than present a pre-worked out setup. Cheers
yeah! was looking forward to this
Marvelous video. I do like Graham. Results vary. However your initial thoughts still hold true. Beefy VRM's is best long term.
