Interesting video on the 3080 crashes being reported on reddit/LTT and elsewhere (https://www.reddit.com/r/nvidia/comments/izhpvs/the_possible… https://linustechtips.com/main/topic/1248333-rtx-3080-crash/)

Maybe good luck to all those who missed out on getting a 3080.

Note that in Jayz videos he calls out ASUS for using 6 of the more expensive arrays but all the pictures of the ASUS cards that I've seen show 6 of the cheaper ones.

Edit: From ASUS's own website looks like its only the O10G model https://www.asus.com/Graphics-Cards/TUF-RTX3080-O10G-GAMING/… the rest appear to have the more expensive arrays.

    This post has a reply that's tracking which 3080s cards have the cheaper POSCAPs and which have the more expensive MLCC arrays.

  • jaymzrsa on 26/09/2020 - 09:56

    That Reddit post tracking the cards, you da real MVP.

    Thanks for the share, I'm on the FTW3 Ultra bandwagon so hopefully I'm in the clear.

  • johnnyg on 26/09/2020 - 10:21

    Yeah i read this but the author and that Igor guy that broke the news said its speculation at the moment. I have ordered a Zotac myself.

    The 2 good Asus cards with good capacitors have had crashes also supposedly

  • Icant Isimplycant on 26/09/2020 - 11:12

    I preorded the EVGA XC3 with the single MLCC, thinking of refunding if more issues crop up or if they don't come up with a reasonable solution.

    I found the same thing as OP, Jayz showed 6x MLCC array on the ASUS TUF card but the one on PLE shows 6x POSCAP. I can't find any to buy with the 6x MLCC.

    • Ori0n on 26/09/2020 - 11:48

      The single MLCC array is nvidia min spec so you should be OK - but worth keeping on eye on updates.

      • xuqi on 27/09/2020 - 00:09

        Nvidia 3080 FE uses 2 MLCC array's.

        • Ori0n on 27/09/2020 - 07:08

          Yes, the FE is higher than min spec. NVIDIA send a minimum specification to AIB manufacturers. They may or may not be different to what the FE cards end up being.

    • shiningblade on 27/09/2020 - 14:53

      Note that MLCC has better performance under high frequency, it makes some high-frequency noise at the same time. It is unclear now if 6 MLCC design will make some sharp noise after a certain load. Personally, I expect a combination of MLCC and SP-CAP will be the best solution.

      thats fine stop listening to fear mongering posts

    It should be clear from the PCB photos which cards are likely to be the ones having trouble, e.g. out of the ones below just the Zotac trinity looks like a problem.

    3080 OK list!
    NVIDIA GeForce RTX 3080 Founders Edition
    Palit GeForce RTX 3080 Gaming Pro OC
    ASUS GeForce RTX 3080 TUF Gaming OC
    MSI GeForce RTX 3080 Gaming X Trio

    3080 NOT OK list!
    Zotac GeForce RTX 3080 Trinity

    3090 NOT OK list!
    GIGABYTE RTX 3090 Eagle OC

    If anyone finds PCB shots of other cards please let me know and I'll add them to the above list

    Not going to lie, it's in my best interest to know, I don't want to be RMAing 100s of cards 😂😂😂
    I will at least be putting orders from suppliers for potentially problematic cards on hold (possibly cancel them), at least until there is a clearer picture on what's going on, or the issued is confirmed independently from other reviews. Keeping an eye on Gamer's Nexus and Buildzoid 😀

    Also I think having a mega list will be valuable for everyone to check their card they have ordered (potentially with time to cancel and switch to a better card).

    It sounds like there is a little more to this than just the types of caps. People are reporting taking items off the same power board can solve the issue. That make's it sound like these cards should be filtering the 8/12 pin and PCIe power.

    Yes, better filtering just the GPU seems to solve this issue, but you would most likely see higher memory speeds too if you could stabilise the voltage across the card instead of just the GPU alone.

    I am planning to wait another 6 months and everything will be sorted and plenty of card available to choose from
    first production run always has teething issue

  • johnnyg on 26/09/2020 - 18:49

    I was about to cancel my Zotac preorder and ask for a refund but they make it clear on the teardowns its only the cards that are overclocking not stock. It's always gonna be unstable when you're overlocking

    The crashing with the RTX 3080 cards doesn’t appear to be down to the caps used, which is why we haven’t made a video yet, we don’t know the issue. What we do know is the FE and TUF Gaming models crash just as much as other models and they use MLCC’s.

    • petry on 26/09/2020 - 19:49

      oh dear crashs - shocked and horrified to hear that overclocking causes issues with a card…

  • pc6673 on 26/09/2020 - 21:12

    EVGA wins, harvest reputation at the right time….

  • Shaunzki on 27/09/2020 - 17:02

    So any news on the Gigabyte Eagle? Considering many of us have purchased them with Techfasts build I am concerned.

    • xuqi on 27/09/2020 - 19:38

      It's built using the cheap config (thei 3090 is also built using the same config). At least they've used the nicer 470µF bypass capacitors. Zotac who seem to be having most reports of issues opted for the cheaper 330µF parts.

      https://www.techpowerup.com/review/zotac-geforce-rtx-3080-tr…

      Nvidia are most likely going to need to release a BIOS that contriants the GPU boost.

    https://www.youtube.com/watch?v=FmmlafdRlvw This was a good video that explains the situation a bit on the differences between the 2 caps. Very well done video and super informative.

  • gelilloabad on 02/10/2020 - 00:48

    This is the only video you need to see about 3080 and the capacitors issue: https://www.youtube.com/watch?v=lhyCdraz54s

    TL;DR
    - Capacitors were not the issue
    - It was a DRIVER issue
    - MLCC are not bad, just different.
