Here's why your Nvidia RTX 3080 may be crashing
The reason for crashes with some of the Nvidia GeForce RTX 3080 graphics cards appear to be down to bug with capacitors.
Last week it was reported that a suite of RTX 3080 cards, by and large those that come with a manufacturing plant overclock, were causing crashes to the desktop once the GPU went above 2.0GHz. At present graphics card maker EVGA has come up out and declared that the issue is with the type of capacitors it uses on its accept on the RTX 3080.

"During our mass production QC testing we discovered a full six POSCAPs solution cannot pass the real earth applications testing," the visitor said in a blog mail. "Information technology took about a calendar week of R&D attempt to detect the crusade 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. At that place were no 6 POSCAP production EVGA GeForce RTX 3080 FTW3 boards shipped.
"Merely, due to the time crunch, some of the reviewers were sent a pre-production version with half dozen POSCAP'southward, we are working with those reviewers straight to supplant their boards with production versions."
Put into basic English, the cards EVGA was referring to use a different capacitor design to those found in the Nvidia GeForce RTX 3080 Founders Edition, finer a reference graphics menu. Igor's Lab theorizes that a different gear up of capacitors used on the rear of the printed circuit board that sits beneath the actual GPU of the RTX 3080 graphics card is to blame here.
It'due south down to the RTX 3080 using POSCAPS (Conductive Polymer Tantalum Solid Capacitors) and MLCC (Multilayer Ceramic Scrap Capacitor) to filter voltages to the GPU. RTX 3080 cards can either use all POSCAPS or a mix of POSCAPS and MLCC capacitors.
Our sibling site Tom's Hardware explained that MLCCs are cheaper, smaller, and perform well at higher clock speeds, while POSCAPS are bigger, more than expensive, merely take ameliorate resistance to cracking under heat. Notwithstanding, POSCAPS aren't as good as MLCCs when running at high clock speeds.
With all that in mind, it would announced that EVGA'south employ of an all-POSCAPS design is causing bug with its RTX 3080 cards. This has seen information technology switch to a mix of POSCAP and MLCC.
Withal, this may just be an issue with before EVGA cards that got shipped to reviewers, whereas at that place are reports of crashes to desktop that affect other RTX 3080 cards from other manufacturers and even Nvidia'south own cards.
As such, information technology remains unclear if the capacitors are the problem behind the crashes experienced in other cards. If this is indeed the case, then the RTX 3080 cards people take managed to get their hands on might have to be returned to the company that made them. That could inconvenience a lot of PC gamers rather severely.
While the RTX 3080 sold out in mere moments when information technology was released and is withal hard to get concur of, we suggest you continue with caution here.
We've heard nil from Nvidia about the bug people have encountered. So it'south worth exercising a bit of patience until at that place's more than clarity behind the RTX 3080 crashes and whether they tin can exist fixed with a driver update or a more than severe gear up is needed.
