No one considers or notices that they are talking about the wrong subject.
It really doesn’t matter for our purposes, though. The terminology was used by Igor and now others are using it. I don’t know that EVGA’s (or anybody’) electrical engineers/board designers are commenting here to correct the dialog. As you point out, the markings are pretty cryptic and sparse. When surface mount components come out of the carrying tape/reel, it’s tough to know much about the component without measurements. There’s also a language barrier involved. What matters is there are two different kinds of caps, two different reasons for being there. The MLCCs are likely there to filter the high frequency switching noise, and the poly caps are probably there for ripple. And even the true purpose doesn’t matter. What matters is the poly caps didn’t seem to do a good enough job for whatever reason and the MLCCs were needed to reduce the remaining noise even more.

Hi all,
Recently there has been some discussion about the EVGA GeForce RTX 3080 series.
During our mass production QC testing we discovered a full 6 POSCAPs solution cannot pass the real world applications testing. It took almost a week of R&D effort to find the cause and reduce the POSCAPs to 4 and add 20 MLCC caps prior to shipping production boards, this is why the EVGA GeForce RTX 3080 FTW3 series was delayed at launch. There were no 6 POSCAP production EVGA GeForce RTX 3080 FTW3 boards shipped.
But, due to the time crunch, some of the reviewers were sent a pre-production version with 6 POSCAP’s, we are working with those reviewers directly to replace their boards with production versions.
EVGA GeForce RTX 3080 XC3 series with 5 POSCAPs + 10 MLCC solution is matched with the XC3 spec without issues.
Also note that we have updated the product pictures at EVGA.com to reflect the production components that shipped to gamers and enthusiasts since day 1 of product launch.
Once you receive the card you can compare for yourself, EVGA stands behind its products!
Thanks
EVGA
Jacob, will EVGA be addressing the POScaps on future XC3 cards or will the stay the same?

Huge relief - glad evga is on top of this. Also mad props to igors lab and others who figured out this could be the issue

People receiving cards with no retail packaging this shows one with 1 MLCS stack XC3 Ultra. Must of been a real rushed launch because of this MLCS issue no retail packaging. https://www.reddit.com/r/...eggca_just_the_gpu_no/

It's already been said but all MLCC doesn't necessarily means it's better. It's like eating, you don't eat ONLY fat OR sugar OR protein. You need the 3 of them, but you need them to be well balanced so that they can each be used by your body. Same goes for electronic components, they each have their purpose and using too much or too many of them can cause issues or just not work well between them, same your body would.
Saying that because they used expensive stuff you'll go there doesn't make sense. They could buy expensive stuff and use it poorly / in a non efficient way. It's not only what you buy but how it's assembled and how components interact with each other that counts.
Example : Buying a Quadro and a Threadripper for gaming because it's more expensive and has more cores (for the threadripper), you'll see that on gaming your results will be very bad compared to way cheaper stuff. Because you need to use stuff in a way that makes sense.
Using 60 MLCC does not mean it is necessarily worse. ASUS tests their hardware before release just as much as EVGA, maybe even more so. I'm going with ASUS on this one and buying their 3080 Strix OC GPU.

So what d u think about this:
I was actually just rooting around Digikey looking at Panny's current lineup, and yeah - POS !== SP; Tantalum handles things a lot better, and approaches MLCC with some of the newer kinds; but as others have pointed out, the issue is now that people have the terminology, they don't care - there's an issue with the sections and while i'd love people to start to differentiate between the tantalum and aluminum variants, I don't think people are going to care unfortunately even as it pains me hahaha

EVGA already addressed this at least - Newegg seems to have been in such a hurry to fill orders they bought bulk shipments made for prebuilts and shipped them out instead "an's orange an orange, right"

First, thank you Jacob and EVGA for the transparency.
To everyone complaining that it's too little or too late, consider this: Most companies that offer a product do not give any insight into the R&D process at all unless they have a customer who is helping to beta test it. I work for an IT company and we never tell customers about issues during development. This is not to be expected of any company.
Find another AIB partner with this much transparency. I'll wait.
Even with all that said, it is still not clear this is the entire issue. It seems like the reference design that nVidia went with already pushes these cards way harder than previous generations. This equates to lower overclocks due to having very little overhead. Don't expect to push these cards as hard as previous generations because nVidia is already pushing the platform near the max with reference clocks.

Asus is using all MLCC's for their cards and they sell Tuff at MSRP. I dont think I am going EVGA anymore.
I am waiting for now to see what happens with the 3070. Probably gonna get a Tuff version instead of the XC3. I wont get price gouged and they will use better components.
Agreed. I'm also going with the ASUS Strix OC 3080, at least for this launch. I'd rather have all 60 MLCC config of the ASUS than the 4 POSCAP + 20 MLCC config of the EVGA FTW3 Ultra.

The 3080 Ultra FTW3 graphic on the EU site hasn't been updated to show the correct cap design.

Yeah it's the wrong terminology, but you can tell who is just parroting the article and who actually knows something about electronics. They are just Tantalum and Ceramic caps as far as I'm concerned.

Are the 3090's FTW3's affected also, or is the solution already addressed on them.

I seems that the 3090 XC3 was updated to the 4x2 design as I snagged one on launch day and it’s has only 4 POSCAPS with 2 MLCC. Here is a pic...

The EVGA RTX 3080 FTW3 ULTRA Gaming stock photos still show the 6 POSCAPs instead of 4 + 2.
Have a link? I looked at the product page and it's changed. If you've looked at it before, maybe you need to clear your cache. That's what Jacob was recommending if you're still seeing the stock photo.
Yup, you are right my friend, I needed to clear the cache, I didn't realize it was still displaying the old photo even though I was refreshing the page... damn cache. Thanks for the tip, looks ok now (4 POSCAPs + 2 MLCCs) :)

So the XC3 only has one set of MLCC, but the ftw needs two sets? Seems like a good idea to cancel my order if nothing new comes up...

I was so excited I scored a XC3 Ultra from Amazon I honestly just dropped any and all 3080 news immediately.
Jacob mentions the XC3 should be fine, but have their been reports of issues with it?
