GIGABYTE 3090 MASTER Capacitor Quality

Recommended Posts

Posted · Original PosterOP

I've been looking at reviews for the 30 series cards and that if some cards have the cheap capacitors in them, they would cause issues when the cards OC'd themselves past 2GHz. Would anyone happen to know if the GIGABYTE RTX 3090 MASTER 24G has the cheap or expensive capacitors, or is this only applicable to the 3080 cards?
Thanks heaps

The "cheap capacitor" rumor doesn't sound right. It is far more likely that some people have incompatible power supply units or they received a defective unit. The 3090 FE can sap 450 watts; it won't be surprising if the Gigabyte 3090 overclocked one requires more at peak.

Don't thank him yet. This is a good explanation of the problem...

without a wall of text, after looking this up for hours, i'm leaning toward crappy binning and cheap caps BOTH as the cause of the crashes.

 

Not 100% of the ampere cards will boost to 2000mhz but they are shipped as such. lowest bin for turing iirc is 1920 but they boosted much lower stock.

 

Some cards are likely shipped with an unstable "stock setting" that's above the base boost clock.

 

It's gonna be a shitshow, tell owners to downclock their cards and they'll feel ripped off, better yields take time. Wait for the problems to be resolved.

Thanks for the help guys:) at least the Strix cards seem to be properly built. If all else fails just get one of them :P

Looks like the ASUS tuf was the card to get it has all the good caps on it:

Except they aren't POSCAPs. As explained in the video I linked, those are a Panasonic brand cap, which is not used on any currently available PCB pictures for the RTX 3000 series. They are all SP-CAPs or MLCC.
