Strangely why are they still making b450? Excess of chips. Pcie4 validation is more expensive than thought?

because b450 chipset is still on going. amd hasn't stop providing b450 chipset yet.
gen4 requires lots of things like good pcb material (mid/low loss grade), gen4 slots of pcie and m.2, switches/redrivers/clock generator etc.

Hello everyone,

Almost new to overclock, I'm basically upgrading from a i5 4570 to ryzen 5 3600 or probably waiting for ryzen 5 4600.
I'm in search of a good bang for buck MATX motherboard. I'm not too into manually overclocking I think I'll do just PBO.
What would be the best board between price, quality and performance for a ryzen 5 4600/3600.

PS. I've watched some reviews and one that catched my attention was from bulldzoid choosing the b550m aorus pro as best bang for buck.

Thanks for your help!

some b550m vrm temp comparision, tested by thermocouple, with watercooled 3700x 1.6v 140w, on open test bench, no airflow
https://www.bilibili.com/video/BV1mD...34119356521408

biostar gta 6*90a sps, mosfet 72c; heatsink 67c

Asus tuf 8*50a drmos, mosfet 47c; heatsink 46c

msi mortar 8*60a sps, mosfet 42c; heatsink 42c

asrock steel legend 8*50a, mosfet 62c; heatsink 57c

gigabyte aorus pro 10*(1H+1L); mosfet 63c; heatsink 64c



for 6c12t I think lots of b550m are capable to handle it.
not sure the prices in your country, so make your own choice.

Interested in the ASrock B550 Steel legend, but it seems the B550 MAG Tomahawk is far better...?

a review seriously complains about b550m aorus elite, despite it is on sales at ~$86usd from msrp $109usd on china.
https://www.bilibili.com/video/BV1E54y1S7yB
gigabyte b550m aorus elite
vcore vrm 5*1H+2L
however, there are 5 low side mosfets on the back pcb without any heatsink, same thing what gigabyte did on x570 gamingx.

other shortcomings:

1*usb 9pin internal header only, instead of 2 on b450m elite.

any gpu thicker than 2 slots will take some space over the bottom pcie x16 slot, namely this mobo support no other pcie device/card when >2 slots gpu is installed.
good thing is then supporting 22110 m.2 and that m.2 avoids hot exhaust air from gpu and no height limitation of m.2 heatsink.

the second m.2 slot is pcie3.0x2 only instead of x4, same as b450m elite.
but it should still be faster because of the pcie3.0x4 between b550 chipset and cpu, rather than pcie2.0x4 between b450 chipset and cpu.

3 fan headers only instead of 4 on b450m elite.

poor sata headers placement just like b450m gaming, worse than b450m elite.
have to use L shape sata header cable for headers under 2 slots gpu.
sadly there is only 1 L shape sata header cable included in the box, another included one is with both side vertical headers.

wired bios flashback button location on the pcb rather than on the i/o side.

vrm temp of the back low side mosfets,
118c and black screen eventually @ 3900x 1.4v 4.4ghz fpu ;
109c @ 3800x 1.4v 4.4ghz fpu 145w ;
105c for stock 3900x @ 3.95ghz only.
(room temp 25c, aio cooling, open test bench)
=>140w seems to be the max "safe" level before black screen/reboot/drop frequency on this mobo.

what cpu are you going to use

both are good enough to handle these two cpus.
btw please note that the steel legend second m.2 is pcie3.0x2 only instead of x4.
i would choose tomahawk if the prices are close.
