VRM on the new AM4 motherboards - Page 141

post #1401 of 1994
@ virpz I think the Sinopower on the Asrock X370 K4 is SM4337 high side + SM4336 low side (same for the Killer SLI).

I should note for those of you who do not understand the principles of cold and how they effect power consumption.

The VRM temps on this board at these clocks and this voltage regardless of the fact that I have clocked it higher may actually be working less due to the fact that I have not increased voltage.

It will pull more from the air OC @4050 to phase @ 4.3 but it will draw much less since I am cold versus air...tbh I am probably breaking even at this point give or take.

this is correct - i have verifyed on 3 killers, and 2 K4s.

gt7 is IR 3555 confirmed not 3550

K7 and gaming 5 has identical PWM phases so your SOC on one of them is a typo tongue.gif

X370 Gaming K4 can also come with NIKOs:

technically speaking with the VRM it does not deserve the model K5. I like K4 better tongue.gif

Look for "Single phase" failures. Those are due to incorrect manual phase setting.

When not in need of more power, the best approach is to set the phases on the most efficient configuration, usually that's by leaving the said technology on with automatically selected number of phases. On high end boards, that rarely means using all the phases at full stock load.

 

Keep steering the discussion in the way that suits you best while attempting (not very successfully I might add) to evade all flak you catch by being constantly and consistently called out for not knowing what you're talking about.

 

Really. It's a very interesting exercise.

Impressive. So the GT7 is well on its track to being yet another TA890FX eh!

I agree. biggrin.gif

virpz, is there any data you can share to proof your infos about the Biostar X370GTN?
I'm quite curious about those VRMs since those look quite awkward on the pictures from Biostar but I still haven't found any better pictures on the Internet.

Yeah, I know nothing. Enough is enough already.

Hey br0da

His list has both versions


Also I think if someone wants to make a list separately off hardwareluxx ' s it ought to have more information otherwise it's a redundant exercise.

Maybe add inductor + capacitor ratings. Inductors are a bit more difficult but the capacitors might be the only VRM differences sometimes such as x370 Krait Gaming vs x370 SLI PLUS). It's a large undertaking however.

i.e. X370 Prime pro appears to use "5KW48" with 820 and 3V written under that , for the caps. (source https://www.bit-tech.net/hardware/2017/03/30/asus-prime-x370-pro-review/1) <-- MILR68 and "16 52 6" written on chokes
CHVI Hero uses FP10K with 71cz and 561 written under that , as well as FP10K with 6Zcz and 101 written under that presumably for SOC ( source: http://www.kitguru.net/components/motherboard/luke-hill/asus-rog-crosshair-vi-hero-x370-motherboard-review/3/)
X370 Gaming 5 uses something with FP and 61C6 and 561 written on it (https://www.overclock3d.net/reviews/cpu_mainboard/gigabyte_x370_aorus_gaming_5_aorus_review/2)
X370 Taichi uses FP12K with 6ZA3 and 561 written on it (https://www.tweakpc.de/hardware/tests/mainboards/asrock_x370_taichi/s02.php)
