One other question why does system profiler only state 256k in the external L2 Cache?

Just realise my times wrong

It's either wrong, or the cache might be disabled (doubt the latter, but it is possible). System Profiler wasn't great in that era. It reports incorrect CPU speeds, wrong processors, doesn't show USB or FireWire busses... All sorts.

Gauge Pro reports 1MB.

Yep and so does Metronome

Oh forgot to mention I tried that G4 enabler its in the sonnet installer if you select custom install and there was no change so defo a G3

It is technically possible to swap a G4 in (CPU core voltage is different, but otherwise the 7400 interfaces are very similar), but like I said, in OS9 it isn't worth it.

Almost the only stuff that probably take advantage will be Adobe and Apple software like Photoshop, Premiere, iMovie and iTunes.

Truth is, I tend to buy faster G3s rather than slower G4s, because G4s cost a premium and for my interests (I don't run Mac OS X much) the clock bonus is worth more to me.



Photo is BeOS running on a 466MHz G3.

Little update from me

Here is pictures of the 2 cards I have side by side

I did notice the serial number on both starts BG3 so maybe the wrong sticker was stuck on it?

the major difference I see is the component on one side (Capacitors I believe) and the Xilinx chip has a different version stated on the sticker that's about it.

Weird, looking at your cards, I also wouldn't expect there to be a 400/512k. The 400MHz cards were fairly premium and all the ones I've seen have 1MB of cache. Although I can see other 400/512s on eBay, so that must have actually been a thing.

Did these two cards come together? Did you get them from the UK or were they from somewhere like Japan? Do you own a sticker printer?

I didn't realize you need software for the upgrade cards. What would I need for the 500mhz Sonnet Crescendo in my G3 minitower?

The G3 minitower is a Encore rather than a Crescendo:

I get a 403 error on that link. What's the software called, so I can search it?

Edit: found it.

No as i said the one marked as a G4 came in a bundle of Mac OS CD's I bought, I wasn't expecting it to be there but at the time I didn't have a computer for it to test with.

The G3 400/512k came with my Performa 5400/180

This G4? 400/1MB is in my Powermac 5500/275 which is actually a 250 because the 275 Mobo that came with it isn't very well sadly.

Oh, BTW... You can software overclock those Sonnets.

Interesting it there a thread on this?

Here you go - this only works with Cards fitted with a version 3.0 (or higher? If they exist) G3 chip, which your photo of Gauge Pro shows you have. Store the original extension from System Folder>Extensions and replace it with with the attached and your card should run at 500MHz. If it can't handle it (too fast/hot), booting with shift held down will disable it so you can swap them back.

That's all that is needed.

Previous discussion on this site from when the original site dropped off the internet :

https://68kmla.org/bb/index.php?threads/the-6400-zone-down.42460/

The linked archived page goes through the history, and the application I attached in my old post lets you pick the clock speed (if you can't get it to run at 500 stable, perhaps it has a 450 setting? Or add a fan).

Sadly it doesn't work for me it gives an illegal instruction error when loading the extension.

But it could be my setup missing something important

Could be just too much overclock - 25% is not a small speed bump. I usually aim for 20%, its just the pre-made extension already existed.

You could see if 450MHz works by making a copy of the /original/ extension you previously had installed, and using the application shared on the thread I linked to modify it. Just delete the 500MHz version, its either faulty or too fast.

Or just use it at 400MHz, which is pretty fast to be fair. My 6500 isn't that fast

 

[Timtheloon]

Yeah I think it's gonna stay as a 400mhz it crashes with every over clock attempt I try. but as you said 400mhz is quite speedy
