So I have the 3080 xc ultra and I'm getting major hitching in most games, anyone else experiencing this?



My XC3 Gaming which seems to have the correct layout as described in the initial post (1 MLCC/5POSCAP) constantly crashes during games, I have reinstalled the nvidia drivers, downclocked the gpu by 20mhz (which I think is enough?) and adjusted the temp/power target of the card.
 
Still crashes to desktop and/or CTD and BSOD, never happened with my 1070 in-game, tbh this seems like a driver issue. Crashed in Doom Eternal and Mafia Definitive edition.

LOL.  Told you so.
 
Edit: so it sounds like they had to swap them out at the factory in Asia, not stateside.  But I was correct in that it is what caused the delay.


And do you think this is what caused the shortages or no?




Just the delay of the FTW3 3080 card.  They had to swap out parts on already built boards, I think.  I gave estimates of 10-30 minutes per array elsewhere.

Thanks for the reassurance! Glad I decided to stick around and wait.

I just hope it's all fixed before I get ahold of one.

Im also waiting for my 3080 FTW3
little strange:
Asus cheap B line TUF: full 6 MLCC 
EVGA not so cheap A line FTW: only 2 MLCC and 4 (cheap) POSCAP's

Looks like the photo has been updated for the 3090 XC3, and it's got the 4 POSCAP + 20 MLCC config:

i could really use someone ELI5 on the differences in the configurations.  i see many seeing the Asus version with the 6 of 6 MLCC is actually not desired.  Why is this? lower life span? what is lower? 6 years vs 8? 10 yrs vs 15? at what loads?  Does this apply if we watercool these cards?
 
lots of questions  : /

at 1:57:00 Jacob calls Steve from Gamers Nexus.

All EVGA production cards are GOOD TO GO! Zotac, Gigabyte, and other Chinese companies have had to downclock. Looks like EVGA solved issue prior to prod!!!

Hope this helps~

Is it safe then to buy any of the XC versions? even the Black edition?

Hi, I assume the fix described for the 3080 is also being applied to the 3090? I have one coming in a new PC build that is underway.
Thanks
Mark
 [Edit- just saw the photos of the 3090, so question answered. Sorry I didn't catch it sooner, this was my first post here]

Are you an electrical engineer to understand the need for MLCC?  Serious question as I'd like to know why 6 MLCC would be preferred.  I have very little knowledge of electrical components and their interoperability among other components.  I just know that EVGA tested all their cards and works as intended with GPU Boost (they better as it's Advertised as a feature).

'The BoM and the drawing from June leave it open whether large-area POSCAPs (Conductive Polymer Tantalum Solid Capacitors) are used (marked in red), or rather the somewhat more expensive MLCCs (Multilayer Ceramic Chip Capacitor). The latter are smaller and have to be grouped for a higher capacity.
According to the list and specifications of Nvidia, both are possible. In terms of quality, however, good MLCCs are better able to filter the very high frequency components in particular. In the end, this is simple practical knowledge, which only often enough collides with the world view of a financial controller.' (from Igorslab.de)

Well the MLCC's stacked together work in harmony together.  Having a bunch of small ones instead of one bigger one just means they stack together and work better.

I asked at IgorsLab regarding this topic:
 
Result/Anwser: "Caps are there on the one hand to filter the high frequency components and on the other hand as a buffer to prevent voltage drops. SP or POS CAPs are more shock-resistant and temperature-stable, but fail because of the high frequencies. The FE's 4 + 2 mix is perfect." (Source IgorsLab Forum)

I feel like EVGA kinda cheaped out. ASUS did things right.

U guys knew about this issue weeks, if not months ago...and you are all coming out of the closet now...ONLY BECAUSE OF INDEPENDENT REPORTING. This is not how u build trust...



Knew about the issue and delayed their own product launch to fix it before it got to consumers. That is exactly how you build trust...

Looking at the buildzoid video, it appears that if the Asus cards do in fact use the 47uF MLCCs, then it looks like Asus really went all in and it's a bit disappointing to see EVGA go the hybrid route, at least on their most top end (non-KP) cards...

I think i'll likely still stick with EVGA due to reputation, but Asus is looking super appealing right now, especially that strix.

Thanks for the info.  It'd be interesting to see how the Asus performs then.  Maybe Steve from GN will put it through the paces to find out.

I'm glad you guys were able to catch this since Nvidia kept their drivers to themselves until the last minute. Any idea when more 3090 will be in stock??? lol I'm patient-ish. lol
