What boards? What CPU are you using?

I could use some help with this!

Need help updating a phone from w8.1 to w10 - Windows - Linus Tech Tips

please, pm me if you would like to contribute to my gpu bios database (includes overclocking bios, stock bios, and upgrades to gpus via modding)

This is not something you should focus on, and it's really irrelevant.

The actual number is pointless...  for example, it could be 8  x 70A power stages, for a total of 560A peak current,  versus 12 x 40A stages, for a total of 480A peak current .. .12+2 looks good on paper, for marketing reasons, but no guarantee it's better.

 

It could also be 8 real power stages, versus 12 as in 6 doubled  power stages ... which makes a very tiny difference, almost not worth discussing.

 

And last, unless you plan to buy a 10+ core processor, anything higher than 6 power stages on modern motherboards won't give you any benefits besides slightly cooler VRM.

I am using the ryzen 5 3600x with b450m A pro max. The motherbaord is pretty bad (40-50$).

The 3600x consumes up to 80-100 watts. A 4 phase VRM can power it just fine, but it would be a bit warm.

The B450m-a pro max seems to have 3 phase VRM but they're doubled, so you have 6 low side mosfets ... and if a google search is correct, they're Sinopower SM4503 mosfets which are rated for 60A at 100c  - so you have 6 x 60A = 360 A peak current at 100c  - the 3600x shouldn't get close to 200A (100-150w / 1.0 ..1.4v = 100-150A) 

 

You can see in this video that the guy says a 5600x (which consumes maybe 5w on average less than a 3600x) keeps the VRM at around 60-70c and a 5800x (8 core) that averages around 110 watts gets the VRM up to 100-110c which is at the edge of recommended temperatures (the mosfets are rated for 150c , but the capacitors which are very close to the mosfets will hover at around 95-100c and they're rated for 105c)

 

 

You can easily improve your motherboard if you're paranoid, by getting some of those memory / vrm heatsinks with adhesive tape and placing them on the mosfets.

Here's examples of such heatsinks : https://www.amazon.com/Aluminum-Heatsinks-Conductive-Raspberry-Transistor/dp/B084X4VMP9/

So will it be better if I replace my motherbaord?

Of course it will be better.

Do you have to? No.  

A better motherboard won't make your cpu run faster. It will give you a better pc experience through extra usb ports, maybe better onboard sound, other crap that's not related to the VRM.  The 3600x doesn't make the VRM on this motherboard work too hard, there's not much to be concerned about.

 

If you have 500$ to spend, sure, buy a new motherboard.

If you only have 150$, you may get more value and more performance out of the computer by upgrading your video card for example.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

run HWInfo or CPU-z or Aida64 or any software that displays system information, you want to see the RAM details and frequencies, timings etc.
