Ampere POSCAP/MLCC Counts

Posted: 25 Sep 2020 09:20 AM PDT

Igor's Lab points to choice between POSCAPs and MLCCs in power delivery as possible source of 3080/3090 instability. (Source) This is still speculative but as good a theory as any right now. Also, POSCAPs are a specific Panasonic product line; the correct term is really SP-CAP.

Here is a list of cards by balance of those components.

Product page sourcing may not accurately reflect release versions due to revisions not warranting redoing photo shoots. Some ASUS cards are known to have done this. Many reviewer models are also POSCAP only as they are pre-production.

3070

AIB	Model	POSCAPs	Source
Asus	Dual	4	Asus
Asus	Dual OC	4	Asus
Asus	Strix	4	Asus
Asus	Strix OC	4	Asus

The layout is different from 3080 and 3090, so it is difficult to determine at this time which components are MLCCs and what constitutes a group of them.

3080

-	Founders Edition	2	4	TechPowerUp, Gamers Nexus
Asus	TUF	6	0	Asus

¹ This is a pre-release reviewer model. Colorful proactively stated to reviewer that they knew the card was prone to crashes and that investigation was underway. This may not reflect actual sales. Many companies gave reviewers all-POSCAP boards.

² Not sure which Gigabyte this is. PCB has V20057 designation whereas the TechPowerUp 3090 Eagle OC and der8auer's 3090 Gaming OC have V20058 which makes me think Jay's is 3080. The darkness and angle in the plastic of the cooler makes me think it's a Gaming OC. I was not able to find other clips of this card in his channel. I don't know why Jay doesn't just say it.

³ Board model VCG308010TFXPPB. Not 100% sure this is the correct model but it's definitely a PNY teardown.

⁴ According to reports, Zotac is making an update to their designs.

¹ This announcement specifically names only the 3080, but the 3090 product pages are also updated (see gallery in listings). Corroborated by teardowns.

² According to reports, Zotac is making an update to their designs.

Additional information is more than welcome and will be updated. If you have a card and are willing, you can find this information out easily by taking off the back plate. Components are currently only determined roughly with "big blocky part" = POSCAP and "group of many small parts" = MLCC. While this is currently probably the best information that is available to me at this time, I anticipate that we will know more very soon.

Alternative theories at this point include improper binning on higher end cards due to limited AIB access, bad drivers, other components being bad, or power spikes hitting PSU limits.

To reiterate this is NOT confirmed as the issue. This theory is just speculative at this point from Igor's Lab. As an electronic engineer is pointing out here, this also does not equate to MLCC good POSCAP bad. Until someone pokes an oscilloscope into these things, we do not know.

Please do not jump to conclusions at this point or write off entire brands just because of some unfortunate initial SMB choices; there are much more important long term factors to consider like quality of support. If it really comes down to this, expect some form of fixes or recalls to solve this.

Another list here, information synchronized as of 12:30 AM EST 26 Sep 2020: r/nvidia modpost

Updates:

ASUS, EVGA, and MSI have updated the product images on their official sites for any board with a window showing these distributions. EVGA has made a statement confirming their POSCAP changes on launch. It is important to know that many companies sent reviewers 6-POSCAP models even though the power delivery was later revised due to failing internal testing.

It seems like multiple vendors are scrambling to push updates. I will update as we go, and update again tomorrow morning.

AHOC Buildzoid, whose brain is clocked higher than mine, has some thoughts on the nature of the issue.
