It's my experiences that ASRocks VRM phases are well thought out on a per platform basis.

Asrock has more phases (9 vs 6/7 in total, 6 vs 4 for the cpu) but it doesn't use a doubler to run those all those 6 cpu side vrm phases. So the Asrock is really only a 3 phase vrm and will have lower quality voltage regulation/vdroop by comparison. The vdroop for Asrock is close to 0.1v which is quite large.


I agree there with ya. But you're not coming to well discussed before release terms with the B350 being AMDs Mainstream chipset.

You're seemingly trying to get Corvette performance and handling from a Cadillac. While still a great chipset the B350 doesn't do SLI/CF and lacks 4 USB that the X370 does.

Addressing "doublers' , there's the good, and the bad concerning them yet I won't get into that here. There are very very few AM4 boards with doublers(see below link) from any manufacturer, and then they are the Enthusiast X370 boards.

?? The entire discussion was about VRMs not SLI/CF, or the lack of USB3.2.

Not having doublers means the vdroop can be as big as 0.1v on this model which is 3-4x what is typically seen on other comparable models/brands with 4 phases (vs 6 for Asrock).

But even I can live with that if p-state overclocking to ensure cool and quiet works and multipliers/voltages drop to proper idle levels.


And that lack of SLI/CF and USBs is exactly my point. The B350 is a lesser priced board/chipset that cannot be stood up against a more expensive board. Beit another brands B350 with different VRM layout or maybe a lower priced X370..

Look at the link above. There are no doublers used on any of the B350 boards. And only a few X370s.  Asrock uses a 3+2 layout while others use 4.

Gigabyte and asus B350 have LLC.
And it have P-state overclocking who is much more advanced.
So i think it just copy past some code from another bios.

What G.Skill Kit is that?

It's G.Skill F4-3200C16D-16GVKB 



It's not that good if you compare to:

Hello,

I would like to know if ASRock plan to implement any kind of LLC option in the bios of the AB350 Pro4?

Because for now I have significant VDROP when the CPU is in charge.

When i configure the bios @1.375V, i'm @1.35V in idle and only 1.262V in full charge with prime95.

I use the last version of HWiNFO64 to read the CPU voltage:



The other brands have less phases on they motherboard but seem have less VDROP...
