Rtx 3080 lower quality capacitor Issue

[Rroff]

Hardwareunboxed that claims ASUS Instability has the full array of MLCC Capacitors just like all the retail units did, there was no mix.



The problem lies with a mix of silicon quality, capacitors (because EVGA said they had to change the design so yes it can be a cause), factory overclock and GPU Boost.
Easiest fix is GPU Boost nerf which would be a driver update otherwise all the manufacturers would have to do a huge recall of current stock and flash a lower factory overclocked bios on them so GPU Boost doesn't boost them to that crashing point.

I'm still not really buying the capacitor side of the story - this use of capacitors is generally a cheap and reliable way of hugely increasing your stable operating margins and is usually massively overkill - it is possible the crammed PCB or some other factors make a difference here or someone has really screwed up the design and the voltage regulation is easily destabilised.

Either mixed silicon quality or a bug in the boost algorithm is more likely IMO.

I've seen 3080 strix reviews with 0 MLCC and strix reviews with 6 MLCC.

if you see a strix with no MLCC it's pre production. Final production uses 6 MLCC

How is it speculation if EVGA have confirmed?

3080s are so powerful, when they hit peak boost it opens a rift and you actually go back in time to your desktop before you actually started the game.

Actually?

I need a coffee.

Why would a pre-production review one have 0 MLCC and retail version have 6 ?

If they've gone to the effort to design that AIB card like that then swapping later on implies about cost ?

Bit weird then reviewers then get "better " cards

so you have made your mind up on what the issue is on basis of a youtuber ? sorry but WE dont know what the issue is

I agree with EVGA, I think they know what they are doing.

Manufacturers having to do a product recall would be unfortunate but they should have produced a product that worked properly in the first place.

I have worked in manufacturing all my life and one thing you don't do is make a product worse to get it to work.

People bought those cards based on manufacturers claims, if it says overclock on the box then it should do that.

How has the ASUS TUF got 6 of the expensive capacitors yet is priced @ MSRP?

 

[The Old School Gamer]

Maybe NVIDIA will fix the problem at the driver level?

VBIOS updates that down clock cards would not go down well with customers.
But then again that might not be the fix anyway.
It could be that the boost algorithm just needs a tweak and that clocks over 2Ghz are actually perfectly fine.

I don't fully understand the root cause so it's hard to say.

A huge amount of salt powered self appointed monday morning quarterbacking going on right now. Without all the facts.

I'll ask again - has anyone got/seen the non-OC version?

My understanding is they are not more expensive.
They are just a different type of cap with different characteristics.

 

[Dave2150]

Actually?

Yeap, 100% confirmed this happens.

 

[Joeyuk]

Don't need a new driver at all.

The manufacturers need to fix/replace the cards not nerf them.

As this is a NVidia screw up they really should be picking up the bill.

it doesn’t seem to be a problem with the physical cards. People have jumped on the caps as youtubers pointed towards them but all aib cards seem to be affected including fe. They all use different caps, different configurations, etc.

They are actually cheaper, seems the best setup is a mixture of the two as they do different things.

if it says overclock on the box then it should do that.

It says '1710Mhz' on the box. These claims of power issues supposedly arise at over 2000MHz. 300Mhz higher than what you were advertised.

 

[otester]

Apparently while MLCC is cheaper per component, they are much more expensive/time consuming to deal with during production, causing machine stops, making video checking more difficult etc.

Cheaper per part, but you have to buy and install and test lots of them so not cheaper to manufacture

Nvidia use the hybrid design on their FE boards plus they apparently have less crosstalk and interreference according to their marketing gumpf. I think the truth of the matter is AIBs are learning what is working best for their models as we speak...

It may say that on the box, but from what I undersatand if you just slap the card in, install the drivers and start playing, then GPU boost will occasionally decide to boost you over 2k and then crash to desktop.
There are lovely workarounds for those aware, but to everyone else it will just be a fault they don't understand.
