Hi!

I wonder if someone runs pulsar
in an overclocked enviroment, in that case
what speed are you running it at?

I do...asuscul2, celery 800, jacked up to 1GHz...very easy(asus lets you do it from BIOS) very stable, no heat...yeap thats my baby, take it easy, marko

What is the bus speed for that setting,
are you gaining any DSP power?

Like 25% extra bus speed, gives you 25% extra DSP power?

CW cards work up past 36mhz PCI bus speed (3mhz over spec), but of course this more than likely voids your warranty, so BEWARE.

No, you don't get any extra DSP power, good try. You do get more DSP power if you use a lower sampling rate though! haha.

The only thing that you might get with a jacked PCI bus is a card that burns out a little quicker.

Note that for maximum stability, you should NOT overclock. If you don't follow me with the PCI bus speeds, then you should NOT overclock, it's important that you understand what you're doing and how it effects the rest of the computer.

In fact, to get the most stable system with other DSP cards, it seems like the Intel 815 board is the one to get -- no frills, no overclocking, no tweaking -- just rock solid.

But I like tweaking and overclocking, thats why the CUSL2 is KING :]

Thanks for your posts!
Yeah, I have a CUSL2-C myself, but dont run
overclocked, was just curious since I too like tweaking and moding

Dont know actually why I thought one would gain any DSP power by inceasing pci bus speed, maybe I for a twisted moment thought the Sharcs run at a frequency that was a multiply of the bus speed, but that sounds just silly now


But I dont honestly think that running the cards a little overclocked would seriuosly shorten the lifespan though, since your post imply that the Sharcs clockspeed is uneffected , and by that also the ammount of heat they are developing...

...yes, the sharcs are still @ 60 mhz, but the <i>pci-interface</i> of the card is overclocked then... that´s why it burns out more quickly

overclocking and dsp, you do gain dsp power by pushing the PCI bus but the cards run hotter. I did tests back when I had to OG cel 366 clocked up to 550 when I would push the pci bus past 100mhz I could then get two of the origional vocoders when before only one could load. . . for what its worth I decided not to do it cause you can fell that the card runs hotter and thus the life of you pulsar will be shortened.

<i>"when I would push the pci bus past 100mhz I could then get two of the origional vocoders when before only one could load. . . "</i>

Ryan, I would venture to guess that the difference you're seeing is not one of DSP power but <i>PCI bandwidth</i> (to main memory), since you do get more reverbs going from 66FSB celeron to 100FSB oc celeron as well...

Ryan... 100mhz PCI speed? I really doubt that:)) OC'ing 333mhz or so to about 500 will give a PCI speed of 33*(500:333)=50 mhz or so. And I doubt that many of your PCI components, especially your HD's, would like running at that speed.

he certainly meant that he overclocked a celery with a 66mhz-bus to a 100mhz-fsb... so the pci-bus runs at nearly 50mhz. in the 1.0 manual CW wrote their cards may take up to 44mhz, that would be the pci-frequency of a 100mhz-bus overclocked to 133mhz... i don´t know if it´s still contained in the quick start guide (i haven´t read the second one that much )

however, i <i>don´t advise anyone</i> to overclock his bx-board (while bx might best @ 133mhz, hehehe... ah, don´t forget the agp which runs at 89mhz then... voodoo-cards like it that hot...)

is there a way to OC the cusl2-c without effecting the frequency of the PCI bus?

I have a PIII 933 and I bet that I can squeeze 1ghz+ out of it . . . but I do not want to OC my children (creamware cards), because I want them to last a long time.

thx 4 hlp!

Yes. You must stick with either 100mhz FSB, or 133mhz FSB, and then your PCI bus is at 33mhz.

So, buy an "E" chip and hope that it overclocks into an "EB" chip. 700mhz "E" chips generally work the best (700 @ 933), but you might be able to get a 750mhz @ 1000mhz now. I wouldn't suggest an 800mhz chip unless it's a Tualatin and you're running an ASUS TUSL2 Your chances of 800@1066mhz are pretty slim. In fact, any normal cC0 stepping has trouble hitting much over 1Ghz.

First of all I fully agree with Subhuman.
Besides getting a PIII 700E/750E you can also buy a Celeron II 566/600/633 which can be easlily oc-ed to 100Mhz FSB.

I'm running a Celeron II 566@850 Mhz which performs like a non-oc-ed PIII 750, but I'd rather have a non-oc-ed PIII EB for memory performance (133Mhz) on my CUSL2-C.

try this, load pulsar and one big device ie vocoder and open the dsp meter in pulsar. load as many vocoders as you system allows, then look at the dsp meter. then move the system bus up past 66/100/133 so that the pci bus (and all cards on it) are overclocked then load the same devices (or project) and compare the difference. I guarantee that there is one and as you would expect you are squeezing slightly more power out of your pulsar. : )
