VRM and ryzen boost

[Lhakryma]

So there's this article about 3900x ryzen cpus not getting the advertised boost speeds, and I talked about it with a friend. He suggested it may also be caused by the consumers having crap mobos with really bad VRM.

 

Would that influence the ability of the cpu to reach the boost speeds?

It doesn't appear to be hardware related.  

 

AMD released a statement saying they have a fix scheduled to be released to board vendors September 10th.

Most decent B450 boards have VRMs that can drive them fine, and the majority of X570 boards are overkill for everything but the 16-core, probs more than the average user needs for that too.

It's certainly possible. AMD will be releasing a new AGESA update to see what can be done but a 50$ B350 or B450 board with poor VRM cooling can certainly cause power throttling. We've already seen it on intel with i7/i9 CPUs hitting power limits on H310 and some B360 boards.

Keep in mind cooling as well, if the board has good VRMs but someone is running an insufficient cooling solution that can also play a role..ambient temps, power supply, software. It's not a simple equation.

Crappy VRMs as more to do with unstable OC and high VRMs temps then it as to do with Boost clockspeed. All Ryzen 3000 are unstable on any board, AMD will sort that out before the end of the year..... i guess

Check Der8auer's video - It's worse than I thought - RYZEN 3000 Boost Survey and the Hardware Unboxed one - AMD 3rd Gen Ryzen Boost Clock Investigation

So do y'all think the x470 aorus gaming 7 wifi will be good enough for the new 3950x?

[Lhakryma]

Looking at the buildzoid video about it, it's apparently overkill vrm for what the ryzen 2000 has to offer, and people say that it's really good for the 3900x as well. Will it handle the 3950x?

The top tier X470 are as good as X570 boards

Maybe so, but IF I were building a rig for a 3950X, I'd consider a mid-tier and up X570 mobo.....I mean, IF I were willing to pony up all that cash for the CPU, why scrimp on the mobo?

I know, i was just answering the question. if your willig to pay 250 bucks for a X470 board, you should consider X570 boards that have probably similar or better features. X570 is an overkill chipset, there are still some overpriced boards but if you have to spend money on an overkill CPU you have to spend money on a board that can support it too, It's like throwing a turboed LS9 in a civic (3950X and a B450 board). If you can get a cheaper X470 Taichi and you don't need the pcie gen 4 then that have to be considered too.

Gosh, I paid mucho dinero for my overpriced X570 board! Just kidding, I'm happy with my choice as I was being true to my philosophy, I'd gotten a 3900X, so I'd felt it deserved a kickbutt mobo...

By overpriced i mean less features/performance than similar priced boards, like that board with water cooling over the vrms and chipset..... for like the price of a car, thats overpriced to me. The same board without the watercooling block is half the price and is waaaayyyyyy overkill already.

Edit: But who am i to judge, i paid for a Crosshair VII......

LOL!  I guess they did over-engineered the X570 a tad too much. The price I'd paid for my X570 Aorus Xtreme was pretty reasonable, in fact lower than the price being sold in the US, same goes with the Asus Crosshair VI Formula.....lower than in the US (each costs about 650USD). The MSI X570 Godlike, on the other hand, is ridiculously priced in my neck of the woods. It's being sold at about 900 USD, at that price, I'd not bothered to consider it at all....

Thanks for the input, thing is I already have the x470 I mentioned because it was on sale

The silicon purity on the CPUs, the truth is that AMD advertised about 100mhz to 200mhz higher than they should have, they went as far as it would go and slapped that into the CPU label with pretty much no margin/headroom to make up for the lesser pure silicon.

 

That's why everyone says that CPU overclocking is not exactly a thing any more on Zen 2, these processors are coming out of the box on their maximum and reason why PBO is preferable than all cores OC through the multiplier (so you still boost higher on few cores).

 

Obviously motherboards matter but the main fault here was AMD being far too aggressive on their own stock settings on their pursue to dethrone Intel... caused this backlash.

Also Ryzen 3000 behavior being all over the place due to unstable agesa updates
