All getting Hyped for the new Ryzen competition!?

So I was thinking of pre-ordering but the lack of decent VRM sections of most release motherboards seems to be straight up awful if you wanna overclock any unless you want to spend 200$++

I'm a cheapskate enthusiast and want to spend as little as possible for great things. Comparing all the boards available I'm disappointed for what kind of power delivery we will be getting with most boards.

Basically all boards arrive with max 4phase design unless you go up to premium deluxe bling designs that all add cost to the absurd when you only want that last part about VRM better the rest you care not much at all about.

With the leak of the new AMD Ryzen 7 1700 65TDP chip hitting max around 3.8Ghz on the cheaper boards mentioned(most 4-phase and cooking). And topping 4.05Ghz on the premium deluxe boards with the better VRM such as Asus VI hero or Asrock Taichi. I'm torn..

I really don't want to spend as much on the motherboard as the cpu in the end. (the cheap Ryzen 7 1700)

Does anyone know which power designs the various boards have yet?

I'm guessing the cheaper MSI boards have those awful 4-array Nikos per phase. (read bad things about those) Unless you like smoked computers.
The Titanium being the most expensive release board with only 6-phase what it seems like doesn't attract.(though I guess they are the premium set of VRM chips(not any NIKOS there)

The Gigabyte mention low(RSD)on and they appear to be their usual design I guess. Vishay?
They seem to be 1 high, 2 low-side design per phase.
Problem here is they have the same design all they way up until their premium boards such as "Gigabyte X370 GA-AX370-Gaming 5".
All lower tier boards have only 4-phase and only at "gaming 5" do we get a what looks like (8+2/6+4)-phase design for cpu power.
And you can get 2 TWO! of the 4-phase boards for the same price as that Gaming 5... Really?

That lowRDSon 4 phase design I've seen been rated to ~140Watt Max with extra cooling unsinked on much older motherboards. Is it still similar?
My old Am2+ board with this 4 phase design cooks on 1.4volts and needs extra fan or extra heatsinks with a old Phenom 1 at 3Ghz..(what the wattage may now be for that old clunker I still use)

They really are tiering out OC only to the expensive boards aren't they?

So what are you supposed to do? It seems like you need an extra 100$ for the better VRM which means you could actually just buy the 1700X instead and keep the cheap board and have same kind of results but now guaranteed with NO OC?

Well, your speculation on VRM manufacturers is just that...speculation. We really have no idea what parts will go into these boards, and if a 6 phase B350 can spit out 150W safely, you'll see plenty of good OC's. My FX-8350 eats 180W ~1.5V full load, so there's no real NEED for 300W outputs on Ryzen.

I recommend going 6-phase like you want (Gigabyte or something) and immediately swapping out the TIM for some Sarcon or something if you're really worried about thermal load.

Edit: We're not dealing with Bulldozer/Piledriver here. We may find that the Ryzen chips do just fine on heatsinked 6 phase boards.

100% agree. Coming from 125~220 watt flagship AMD CPUs I think everyone is a little over concerned with power delivery. 65~95 watt CPUs should be a lot easier on VRMs. Can't say for sure how all this will pan out for overclocking. Can't wait to start seeing results though.

I guess it's not Bulldozer super volcano we are dealing with here but we have no numbers at all for wattage on the Ryzen processors. That makes me a bit worried.

I have a alphacool watercooling kit to transfer so I can cool the cpu no problems with a new bracket so the thing to limit me will be VRM thermals & capability.
I maxed my current MB until I smelt smoke and tuned back a notch and settled. (took some dmg but stable function)

I would have liked a better selection than we got compared what's available in similar prices on older tech.

It's okay (and a good idea) to have a healthy level of skepticism.

Phases don't mean much, what does is quality and capacity. Even with Intel boards you have to cherry pick and avoid any boards with cost cut VRMs :/
Seems the same with AMD, even more so sometimes. Wait for user reviews and summaries with detailed VRM specs. What kind of FETs, caps, coils, how many phases, digital, analogue, hybrid, ...
You don't have to buy a board over $150 usually but you gotta cherry pick. Sadly some brands are moving up in popularity and volume of sales and join up the crazy Asus in making expensive but not that impressive boards. Underdogs on the other hand often try to bring more for less $$$. MSI used to be hated a few years back, certain people wouldn't even touch it, now after all the gaming crazy and gaming branded GPUs and mobos, it's a hype suddenly.

not necessarily. Even if the rated wattage is lower, they could still pull the same amount of current or more. And current is what matter with vrms.

So... the current draw is what is high with fx CPUs and that's why they need quality vrms?

Pretty much. As you can see from every datasheet out there, vrms are rated for current, not power

Yeah that is where I found the first indication 4-phase might not cut it. They mention lower tier boards cooking and only the high-end manage a little extra. Though you pay Much for that little extra few Herz.
4.0Ghz seems like a nice round number but seems it may not be plausible on all cores max with 4-phase the low tiers use.

I know there is difference's in quality the question I'm really specifically asking which boards have the quality parts? As we seem to lack in quantity on many ones.
Seems I'll have to be waiting around for that info.

Cool. I know watts=volts x amps, but I assumed the voltage was more the variable. I learn stuff everyday on here lol

Like 90% of the questions being asked about Ryzen right now can't really be answered. All we know is they are fast at stock speeds, somewhere in Broadwell territory. Oh, and that on liquid nitrogen they are really really fast...like world record fast.

 

[99belle99]

I was just looking through the specs of my current X58 system and my board has a 24 phase VRM. It has been running an overclocked CPU for the past 8 years no problems at all. So I went looking up the current AM4 motherboards from Gigabyte and they have really poor VRM's this time around. What's up with that? I was all set to get a new Gigabyte board but know I'm not so sure. I will wait for reviews to see how they fair.

 

[AlphaC]

I would definitely say that Asrock X370 Taichi , Asrock X370 Fatal1ty Professional (same as Taichi with different coloring and NIC) or ASUS X370 Crosshair VI Hero are the ones to get based on preliminary specifications review. They're the only ones advertising NexFETs used (the CSD87350Q5D normally used is 40A).

Easy math:
Asrock X370 Taichi / Fatal1ty Pro: 16 phases x 40A (hypothetical) = 640 A , assuming that is all for CPU , in reality it might be 6+2 doubled so 12 x 40 = 480A , worst case would be 240A due to doubler
ASUS X370 Crosshair VI Hero : 12 phases x 40A = 480 A , since it's using a doubler worst case would be 240A , it may very well be a 4+2 PWM controller though

The rest of the X370 boards will be a luck of the draw.

For example:
Gigabyte GA-AX370-Gaming K7 : 6+4 PowIRstage (unknown amperage) ... on par with NexFETs if it's the 40+ amp ones (IR3553 = 40A, IR3556 = 50A, IR3550 / IR3555 = 60A), but it has less total phases
---> assuming IR 3555 = 60 A , max possible for CPU = 6 x 60A = 360A
---> assuming IR 3556 = 50 A , max possible for CPU = 6 x 50A = 300A
---> assuming IR 3553 = 40 A , max possible for CPU = 6 x 40A = 240A
Gigabyte GA-AX370-GAMING 5 : 6+4 PowIRstage (unknown amperage) ... on par with NexFETs if it's the 40+ amp ones (IR3553 = 40A, IR3556 = 50A, IR3550 / IR3555 = 60A), but it has less total phases
---> assuming IR 3555 = 60 A , max possible for CPU = 6 x 60A = 360A
---> assuming IR 3556 = 50 A , max possible for CPU = 6 x 50A = 300A
---> assuming IR 3553 = 40 A , max possible for CPU = 6 x 40A = 240A
" AX370-Gaming 5 features a 6+4 phase power delivery design equipped with 4th gen. IR® digital power controllers and 3rd gen. PowIRstage® ICs featuring Isense technology, which provides more precise current sensing accuracy. This helps evenly distribute the thermal loading between the PowerIRstage® ICs, preventing the overheating of each individual PowerIRstage®, resulting in longer lifespan and better reliability."

If you're planning on maxing every clockspeed out, I'd wait for an Asus X370 Crosshair VI Extreme, Gigabyte X370 SOC Force, or Asrock x370 OC Formula. If the Ryzen CPUs are all they claim to be, then those boards should come in the near future if not before Zen+.

The Biostar GT7 has Digital Power+ which may include ir3555a power stages. Ill be removing the heatsinks once it arrives to confirm.

Intriguing indeed. Ferrite chokes, powerpaks, and IR pwm according to the specs available on their page. Not super-alloys and nexfets but it's not bargain-basement d-pak garbage either. I'm looking forward to this board. I've decided to give it a try as Biostar seems to be pushing hard for relevance in the mainstream market once again. I think it will be a pleasant surprise.

That's why I'm not buying into the Titanium or Hero yet. I feel like MSI and ASUS are gauging interest for high-end options with Ryzen and I'm not going to spend more than I have to this early on. I'll revisit it if and when extreme overclocking boards appear.

In that picture that's only 10 PowIRStages. That would only put it on par with a Gigabyte Gaming 5

Given that Biostar appears to be using an ITE chip for fans cooling the CPU and case and I'd rather not bother with them.

edit: I didn't notice that picture was from a LGA1151 instead of AM4, so nevermind

 

[SuperZan]

I'm not saying I expect drastic revisions, but to be fair that is a pic from an LGA board so there might be some differences.

 

[Undervolter]

About Biostars...Before buying, i would let someone else do the guinea pig, especially if Ryzen pulls a lot of amperes and you guys are interested in overclocking. My one and only recent experience with Biostar, showed that they prefer to cut corners on the VRM.

http://www.overclock.net/t/1612857/i-found-out-why-biostar-isnt-selling

Just a word of caution, because all manufacturers cut somewhere and usually they keep cutting corners at the same area for a long period of time. One other note that i observed yesterday doing a quick browsing. It appears that Asrock has learnt lessons from AM3+ and now advertzises 2Oz copper in the AM4 motherboards. Meaning, no longer thin, overheating PCB, which on its turn was prematurely overheating mosfets, causing to throttle. On another note, MSI still advertizes Military Class 4, but again, once you click on details, you only read about dark caps and chokes. Which leads to suspect that they are, as per tradition, using Nikos mosfets on AM4 too. So, one should await for thorough reviews, especially on an untested new generation of motherboards. Aspiring Gigabyte users should also wait to see how much weirdness will be present in BIOS.

My personal hunch, is that ASUS and Asrock will have the more easygoing motherboards. Asrock used to cut corners on VRM in AM3+, but at least, with the 2oz copper it should behave better and BIOS was always easy. It remains to be seen whether Asrock's love for doublers continues or not. Not overclock king, but it should be an easygoing motherboard. ASUS will probably keep overclocking crown. MSI's UEFI seems much better than in AM3+ too.
