With that many exclamation marks though, you're bound to overflow the exclamation mark buffer in the G3, especially if it's overclocked.

Wouldn't the rest of the board still be operating at it's normal slower speed?


That depends on how you decide to overclock, don't it? :-)

Overclocking the FSB is generally more tricky than CPU overclocking (unless you have to do some hardware hacking on the CPU itself, then that's harder :-)), and usually you can't overclock the FSB that much, as you still have to maintain timings with other devices in use, so the benefit generally isn't that great.

I never noticed a difference in my GeForce 2 GTS performance when I had to have the AGP clock to 83MHz instead of 66MHz (due to 133MHz CPU in BX chipset mobo).  That's not to say that FSB overclocking is useless, just a real-life example.

What you were saying about programs being stored entirely in the CPU's internal memory cache.  Don't count on it.  If anyone were thinking that this would be a major factor, run some performance monitoring software specifically for the CPU  (I can't find the software I used to use anymore, I'm going to have to email a mate to find out its name and download it again :-)), then run the apps you generally use to see what kind of cache hit successes you get.

Not really... thats usually the only way to do it these days, unless you unlock the cpu. Most of todays cpu has sadly locked multipilere, i dunno if the g3 has it though...

FSB overclocking is not affected by this lock.. though you might be a bit limited since you cannot adjust the multipilere.

Some do, some don't.  A recent AthlonXP hasn't IIRC.

From what I've seen of FSB overclocking, sometimes you can tweak the FSB without screwing with PCI clock, and most of the time you have to screw with the PCI clock.  And then all you need is one fussy card on that bus.  Like say an SBLive! :-)

Good luck with it Helgis.  Personally I'm happy enough with mine at 800MHz... what's 200MHz between friends eh?  ;-)

This high of an overclock (200 mhz fsb) is impossible since fastest sdram afaik is capable of 166 mhz. itd be possible to push it some more i guess but then you've got all sorts of latency and timing problems, also the agp and pci are locked onto the fsb so at 166mhz fsb you'd need a 5 divider, with fsb 200 you'd need a 6 divider unless you want to overclock agp and pci aswell.

Not that im against overclocking, when it works its great.

Hmmm..i do know that even that the G3 could be overclocked right up to 1Ghz, it WILL get a bit heater than originally...It seems to me that most people just overclocked the main G3 CPU to 933Mhz, and not more...

Maybe i would consider just run it at 933Mhz instead without having to go for a bigger CPU-cooler than that delivered with the CPU...I have to think about it..:-)

Thanks for any good advices:-)
Helgis - AMIGA DEFINITELY makes it all possible!!!

Have other A1 owners really said that they do that? According to my experiences, cooling is essential in overclocking. I'd recommend you to be safe rather than sorry.  :-)
MorphOS is Amiga done right! :)

I have ask for help without going by the mailing-list, as they don't really are so kind of breaking the CPU-warranty by overclocking it...I asked Ole-Egil personally


Geez, when I first read that, I thought Ole-Egil was a Norse God you had prayed to for help regarding overclocking your A1!!!! :-o
I like Amigas

I've used mine overclocked G3-XE @ 933 Mhz, with the original heatsink, for a long time, without any overheating problems.
Anyway I suggest to be on the safe side and use a bigger / better heatsink.

From Ole-Egils FAQ you can work out how to get 933Mhz

1. FSB at 133Mhz multiplier x 6 (default setting) 800Mhz
2. FSB at 100Mhz multiplier x 8 (cheapo memory) 800Mhz

1 = on 0 = off

For 1. dip switch setting on the G3 module are 1 0 0 1
For 2. dip switch setting on the G3 module are 0 1 1 1

x6 ( 1 0 0 1) = Decimal 9
x8 ( 0 1 1 1) = Decimal 7

x6=9 x8=7 therefore x7=8

x7 multipler in binary 1 0 0 0

933 Mhz  ;-)  ;-)

Not that you would do this however as it against your warranty
