De reacties van (sommige) fabrikanten
De gloednieuwe Nvidia GeForce RTX 3080-videokaarten blijken problemen te hebben, met als voornaamste oorzaak een ontwerpfout. Veel fabrikanten waren nog erg stil over de problemen, maar nu blijken veel fabrikanten zich toch te hebben uitgelaten over hun custom producten.
Om het probleem kortweg opnieuw te beschrijven: veel fabrikanten hebben voor veel custom RTX 3080's gebruikgemaakt van minder prijzige condensatoren genaamd sp-caps. De betere optie was het gebruik van mlcc's (multilayer ceramic chip capacitors), maar deze condensatoren zijn een stuk duurder. De RTX 3080 heeft zes condensatoren nodig. Inmiddels hebben veel fabrikanten zich uitgesproken over het probleem.
Nvidia zelf heeft nog geen woord gerept over de situatie. Het is gebleken dat zijn eigen Founders Edition ook gebruikmaakt van de goedkopere condensatoren. Zowel de RTX 3080 Founders Edition als zijn grote broer zijn voorzien van vier sp-caps en twee mlcc's. Een handig overzichtje van Redditor Nestledrink laat zien van welke condensatoren de populaire RTX 3080- en 3900-videokaarten gebruikmaken, en in welke mate.
EVGA heeft, net als sommige andere fabrikanten, zich wél uitgelaten over de problemen, via een bericht op zijn eigen forum:
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!

Dear player friends:
Hello, everyone. Recently, many users have come to inquire about the specific usage of the capacitors on the back of the GALAXY RTX 3080/3090 series of graphics chips. After verification, about the RTX 3080/3090 released by GALAXY. The capacitors used on the back of the model chip are as follows:
1. GALAXY RTX 3080 Heijiang/Metal Master product, the number of SP-CAP capacitors on the back of the chip: 5, the number of MLCC capacitors: a set of 10. This version is currently on sale and is the original commercial version.
2. GALAXY RTX 3090 General/Metal Master product, the number of SP-CAP capacitors on the back of the chip: 4, the number of MLCC capacitors: two groups of 20. This version is currently on sale and is the original commercial version.
3. GALAX RTX 3090 GAMER trial production samples, currently only 6 pieces are in the hands of the media and KOL. The first batch of this sample uses 6 SP-CAP capacitors. After confirmation, the GAMER products officially produced and sold will be used for capacitor materials. Make optimization improvements. Note: This product is not currently on sale.
I am very grateful to the players and friends for their support and love to GALAXY. GALAXY is also consistent in its pursuit of product quality. It is our glorious mission to provide you with better and stronger hardware. In addition, the current full range of GALAXY graphics card products support three-year warranty and personal warranty service. If you have other doubts or questions, please feel free to leave us a message to discuss, thank you! - Galax (Weibo)
Announcement on SP-CAP Capacitors and MLCC Capacitors of Gainsun 30 Series Graphics Card Products
Dear Gainward consumer players:
Thanks to the friends who bought and supported Gainward. Recently, we received the voice of market players’ inquiries. Many players are very concerned about our company’s just released 30 series products. Regarding the specific usage of the capacitors on the back of the chip, we hereby explain the situation:
All the RTX 3080 10GB graphics cards released by Gainward currently use 5 SP-CAP capacitors on the back of the chip and 10 MLCC capacitors. The versions currently on the market are all the original commercial versions.
All the RTX 3090 graphics cards released by Gainward currently use 4 SP-CAP capacitors on the back of the chip and 20 MLCC capacitors. The versions currently on the market are all the original commercial versions.
As a long-term AIC partner of Nvidia, Gainward has always been adhering to the product standard to design and produce completely according to Nvidia’s requirements. Therefore, currently players are concerned about the problem of capacitors and new product failures on the Internet. Currently Gainward has not generated such feedback. .
In addition, all Gainward graphics card products support three-year warranty and personal warranty service. Thank you consumers and players for your support and love to Gainward. - Gainward (Weibo) (via Videocardz)

Update, 12:15: Gigabyte heeft ook duidelijkheid gebracht omtrent zijn RTX 3080- en RTX 3090-producten. Het verklaart dat poscaps en mlcc's allebei hun eigen karakteristieken en gebruiksdoelen hebben in stroomcircuits, en dat zijn videokaarten voldoen aan Nvidia's minimale eisen. Gebruikers die problemen ervaren die gerelateerd zijn aan de stroomvoorziening kunnen hun kaart inwisselen voor een nieuwe variant, zonder bijkomende kosten:
In response to the recent reports speculating that the use of POSCAP capacitors on the GeForce RTX 3080/3090 graphics cards could lead to stability issues and crashes, we would like to clarify the issue with the following statement:
It is false that POSCAP capacitors independently could cause a hardware crash. Whether a graphics card is stable or not requires a comprehensive evaluation of the overall circuit and power delivery design, not just the difference in capacitor types. POSCAPs and MLCCs have different characteristics and uses, thus it is not true to assert that one capacitor type is better than the other.
The GIGABYTE GeForce RTX 30 graphics cards are designed in accordance with NVIDIA specifications, and have passed all required testing, thus the product quality is guaranteed. GIGABYTE GeForce RTX 3080/3090 GAMING OC and EAGLE OC series graphics cards use high-quality, low-ESR 470uF SP-CAP capacitors, which meet the specifications set by NVIDIA and provide a total capacity of 2820u in terms of GPU core power, higher than the industry’s average. The cost of SP-CAP capacitors is not lower than that of MLCCs. GIGABYTE values product integrity highly and definitely does not reduce costs by using cheap materials.
NVIDIA has released a driver (version 456.55) on September 29, 2020 that improves stability. Users are advised to update to the latest driver for optimized performance. For users who encounter power-related issues with GIGABYTE GeForce RTX 30 series graphics cards, GIGABYTE will provide product replacement, free of charge.
GIGABYTE has been constantly improving and optimizing product quality, especially in terms of thermal designs, to provide the best gaming experience to the consumers for decades. For the latest AORUS GeForce RTX 30 graphics card series, we have also paid extra attention to the cooling performance and introduced industry-leading solutions such as MAX-Covered Cooling to ensure that the operation of each component is stable.
Update, 15:32: MSI heeft ook een statement naar buiten gebracht:
MSI became aware of reports from customers, reviewers, and system integrators that there may be instability when GeForce RTX 30 Series graphics cards core clocks exceeded a certain amount. The latest GeForce driver (456.55) includes fixes for the issue. As such, MSI recommends owners of GeForce RTX 30 Series graphics cards update to the latest driver release which can be downloaded from the NVIDIA GeForce website.
MSI stands behind its design decisions for its GeForce RTX 30 Series graphics cards catalog which consists of GAMING models and VENTUS models. MSI utilizes a mixed capacitor grouping in its designs to benefit from the strengths of both SP-Caps and MLCCs. All MSI GeForce RTX 30 Series cards that have shipped out since the beginning of production, which include media review samples, feature the PCB configurations as shown in the updated images below. MSI would like to express its appreciation to customers, reviewers, and system integrators that raised awareness to the issue, and to NVIDIA for the cooperation in quickly resolving the problem.
