Beige G3 w/G4 Upgrade, Need L2 Cache Card?

[LCARS]

In an effort to put my Sonnet G4/500MHz beige desktop G3 to use again, I noticed that it does not have the L2 cache card that the G3 in the attached image does.
Sonnet's Metronome utility also indicates no secondary cache (of course) but it prompted me to ask: Do I need that cache with the G4 card?

That's actually the VRAM slot to take the onboard video from 2MB to 6MB. The L2 cache for both the original processor and any upgrades (G3 or G4) is going to be on the CPU package itself (those two black chips peeking out from under the right side of the heatsink in your picture).

What EvilCapitalist said.

Also, on some very late G3s and G4s, the L2 cache may be internal to the chip and there are no external L2 cache chips. I'm not sure anyone ever made a G4 ZIF like that, though. There were a few PPC750FX and PPC750GX G3 ZIF modules like that.

The FX and the GX brought the L2 cache onboard the PPC chip.

Thank you @EvilCapitalist and @trag. I wish the "more you know" rainbow gif was available. I don't know why I was so convinced that the L2 cache would be there. This wouldn't be my first eBay machine that's missing something. Thank you for the clarification.

I found the LEM PPC history page to be an interesting read. I had forgotten that the Wii was a PPC console. No wonder it disliked YouTube so much at the time.
