B350 with good VRM and a heatsink under $100

[IAEInferno]

Anyone here knows a good VRM and a heatsink under $100

[TrigrH]

all b350 boards have above average VRMs at best, hence they are cheaper.

 

You are basically asking "can i have an expensive cheap product".

Darn that was a retarded question xD. So I should go for the X370 then. If so what would you suggest?

PC Mate, Prime Plus, B350 F Gaming if you can get it for under $100

No, the VRMs on the b350 boards aren't bad enough to the point where it actually impacts OCing. You'll only notice a difference between a b350 board and x370 if you're looking at mediocre-bad b350 board vs best of the best x370 vrms (which would be the taichi and pro gaming)

Asrock Ab350 Pro4 is good. Honestly, any B350 is fine overclocking (but don't get MSI), I HATE it when people spread false information. I have a 1700 with all cores on 3.8 and a b350 just fine. And so do many other people.

Why would you ever buy a 100 dollar b350 board.You can just buy a x370 board at that point

yeah a  half decent 8 core can easily hit 3.8 on a b350 board, but if u want to hit 4ghz, you are going to need something better.

Just save up 10 dollars then get this

Well hitting 4ghz isnt worth the 50-100 percent price increase IMO if you can hit 3.8/9 on b350 (it more depends on chip btw)

How is it a 50 percent increase

You can hit, but the VRMs will go 130+

B350 with best VRMs is Asus B350-F Strix

If you go with R7, then get Asus X370 Prime Pro at least

You stop spreading false information.

ASRock has only 3 phases, you imagine how shitty the voltage control and precision will be

They are bad enough to limit OC potential.  There are some B350 boards that now have "65w only" warnings.

 

B350 Strix and B350 Krait are the only boards with at least mid-range VRMs.  Most all of the rest are not going to cut it with a R7 series CPU above ~3.6ghz.  The average 4+2 VRM B350 boards can hit 100c+ on the VRM at 3.8ghz on a R7 1700.  Strix/Krait end up in the 60c range in the same scenario.

 

If you are using a R5 series CPU, the Asus B350 Prime would likely be fine for a sub $100 board.  Mainly because the R5 chips pull 25%-50% less power vs R7 chips.

Most of the time it is, and if you don't count rebates it still is close. But fair enough.

I got an R5 1600 on a GB AB350 Gaming 3 to 3.85GHz quite easily. The CPU doesn't want to go higher without an obscene amount of voltage...so I settled for 3.85GHz.

VRM MOS topped at 92 degrees C while VRM SOC went up to 77.Temps were recorded while encoding a H.265 clip with handbrake(27min clip, the encode took 1.5h).

Fans were on the quiet profile, thus the high temp.

During gaming VRM usually goes around 66-70 degrees C, sometimes 75. VSOC is usually 3-5 degrees lower.

Ambient temp is around 25-26 degrees C.

I expect temps will go down quite a bit since we're heading into autumn/winter.

You need to tell us your voltage, frequencies dont really matter when talking about VRMs

I got the AB350M Pro4 and i got it to a quick and dirty OC of 3.7 in one try (set voltage to 1.325)

And what exactly is wrong with 100C?

 

Most VRMs out there are capable of going up to 125C. They aren't like your CPUs and GPUs, they can sustain higher temps.

 

It's just like how everyone was blowing up (pun intended) about the evga vrms running too hot. But it turns out they weren't, they were running well below 125C but some people saw 100C and panicked and then cards started blowing up and everyone pointed at the vrms as the issue whereas in reality it probably was just a bad batch of capacitors (see gamersnexus coverage).

 

Also I would like a source for those boards hitting those temps. Not saying you're wrong, just want to make sure it's correct.

The problem is that the VRM temp sensors are not on the FETs.  100c at the senor is likely over 125c at the FET junction, which is over spec and asking for catastrophic failure of the VRM which can take the CPU with it.

If IR thermometer shows 100°C at the back of the board, on heatsinks etc. then yes, it is fine. But on board sensors aren't accurate

Mosfets are mostly fine, but capacitors not. I have a HiFi system in closed cabinet where is high temperature and few capacitors have already failed

Still waiting for a source  

 

Note though, all boards are required to be able to support a full 1800x. Even at 3.8 ghz that 1800x isn't pulling that much more power so I don't see it becoming an issue.

Plus, with a stock cooler that blows air downwards, that's unlikely to become a real issue.

But the capacitors on the boards aren't really at high temperatures.
