EVGA confirms one cause of instability with RTX 3080 GPUs – but don’t jump to conclusions
The Nvidia GeForce RTX 3080 has not only been plagued by stock shortages since launch, but third-party models suffer from instability and crashing. And now graphics card manufacturer EVGA has come forward with some clarification on a possible cause.
A post by Igor’s Lab discusses the possibility that a certain type of capacitor (POSCAP) used on Nvidia graphics cards could be responsible for said crashes, and this ties in with a statement made by EVGA.

EVGA noted in a post on its own forums: “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.”
MLCC is a different type of capacitor, and both it and POSCAP have their own relative strengths and weaknesses. All you really need to know is that EVGA found an all-POSCAP solution unworkable, so switched to a mix of the two different types of capacitor with the final production hardware that hit shelves.
The suggestion which has quickly caught fire and spread online is that a full POSCAP loadout on a factory-overclocked third-party RTX 3080 card (Nvidia’s Founders Edition reportedly isn’t problematic) could mean trouble, and a graphics card that may suffer from the aforementioned crashing issues.
Note that the overclocking is a piece of the instability puzzle here, because as has already been observed, notching clock speeds down by 100MHz is a potential workaround that has worked for some (the crashes seems to occur when boost speeds are exceeding 2GHz).
Caution first
There are good reasons why we should be careful about trying to draw a conclusion that it’s foolish to buy an all-POSCAP RTX 3080 – a list of which has already appeared on Reddit.
These capacitor problems may have a bearing on GPU stability, but picking out the type of capacitor in isolation isn't the full picture. The choice of power solution, design and other components used with the graphics card need to be considered, and the balance of parts is a more complex equation than simply saying ‘all-POSCAP = bad’.
That idea is backed up by Hardware Unboxed observing some crashing issues with the Asus TUF RTX 3080 – which uses all-MLCC, not even a mix – and a further suggestion on Reddit that the Gigabyte cards with all-POSCAP solutions aren’t problematic.
It seems we are a long way from pinning the real problem down. A sizeable part of the issue may be wrapped up in the lack of time that third-party graphics card makers allegedly had to design and manufacture the cards.
It’s a pretty safe bet that this is an Ampere controversy which is going to run for some time yet.

Microsoft Teams on mobile wants to get rid of typos for good
Read MoreUsing Microsoft Teams when running between meetings or public transport may soon be less of a pain thanks to a new update for the service.
The collaboration and video conferencing platform will soon receive predictive text features to its mobile app, a new entry in the Microsoft product roadmap shows.
The new addition should make it harder to make spelling or grammatical errors when typing on the go, particularly as many workers embrace the new world of hybrid working, meaning they may be messaging on a train or bus, or just when rushing to a meeting.
Microsoft Teams mobile predictive text
The entry in the Microsoft 365 roadmap notes that the new feature uses "assistive AI" to predict a user's answers and gives text suggestions so that, "you can finish phrases in one tap."
The tool may use the same technology found in Microsoft Editor, which uses the company's own in-house AI technology to cut out errors across Word and Outlook.
The company recently announced that predictive text would be coming to Microsoft Edge, giving users of its web browser a similar "text predictions" feature that uses Microsoft's own in-house AI and ML technology to offer word suggestions to users.
Microsoft says the feature should roll out to all Teams users by March 2022. It will initially only be available to Android users, however given the huge popularity of Microsoft Teams (which recently topped 270 million monthly active users), it would be a surprise if an iOS version isn't forthcoming soon.
Read moreThe new feature is the latest in a series of recent updates to Microsoft Teams as the company looks to help keep its new and existing users productive and happy across the platform.
Also recently announced was the ability to combine business and consumer Teams accounts, hopefully putting an end to any unfortunate confusion between the two, and even the possibility of adding Microsoft's Cortana voice-recognition software to the platform.
The company also recently confirmed the launch of its walkie talkie feature in Microsoft Teams, allowing customers to use their smartphone or tablet as a walkie talkie that can work over both a cellular or wireless connection.
