75Mhz agp bus 37.5 Mhz pci bus speed

I just overclocked my fsb, agp and pci bus and it works great : )

I remember reading in the Creamware manual that their cards support 37.5 Mhz pci bus speed (from standard 33).

The old IBM chips had 37.5 pci bus and most cards support it.

4.5 Mhz doesn't seem like a massive overclock but when you think about it it's over 10%.

I checked my SFP project loading times and they seemed faster but I could have just wanted them to load faster : )

10% faster loading times could seriously save you MINUTES!!!!! a year!!! if you keep your Creamware cards a long time you could possibly save an hour!!! (depending on how often you change projects and how big they are).

Keep an eye out for a temperature increase if you motherboard is running at a higher frequency. If that's the case, then all your components connected to the motherboard are running hotter. The difference of several degrees has been known to add years to the life of electronic components. Maybe you have all the fans your case can support, otherwise I'd say add a few.

That's why we need them to hurry up with those synthetic diamonds so we can run our Pulsars faster!!

I just wonder if there is a way to overclock those sharcs directly.. Like powerstrip is able to overclock any display adapter's processor.

Don't think that would be possible, as it would affect the frequency that the card uses to interface into the PCI bus. Might also lead to unstable operations, if the SHARCs are running at anything other than the 60 MHz speed.

it's not only the clock, but also the precision of timing. The thing has to divide in 'usable' segments

And the onchip memory will almost certainly fail due to mistiming.

That reminds me on an upgrade I once applied to a couple of office systems: from 32 MB to 96 MB and switching virtual memory off (on the Mac it works with that small mem amount).
Not even one of the workers noticed any difference, though it was certainly more than a 10% improvement

cheers, Tom

ps: I hate overclockers because they prevent me from underclocking my system due to that fixed multiplier bs.
Not personally of course

You can still underclock your system with the FSB. Pentium 4s aren't really bus limited from what I understand so reducing the bus won't drastically reduce performance. Assuming you have a Pentium 4 that is.

Plus an underclocked CPU doesn't need as much bus bandwidth.

I'm very sorry my silly overclocking antics resulted in the fixed multipliers but only because they impede further overclocking action : )

Besides I always thought that the multiplier was fixed to prevent nasty computer dealers from overclocking chips in the store then selling them as faster models?

Not because of bored computer enthusiasts : )

That was a great WIRED article eh?
