CPU upgraded

Is it true that the CPU has been upgraded from the original 2.8 GHz to a 3.0 Ghz of the current production?
(I've been told from the local music instr store personnel)

And, if yes, what's the serial number from which this change has been implemented?

I know this thing too

Even if that is true - it isnt much of a noticable difference i'd imagine. I would guess that if 3.0 CPU's are installed now instead of 2.8 it's more a matter of CPU availability of whomever is manufacturing them and what is left in stock. Chances are small that 2.8 CPU's are still made while mainstream production lines are producing completely different CPU's (for current desktop pc's).

Can't remember who manufactured the CPU in the OASYS though ... is it an Intel?

My quad-core has 700 note polyphony!

An OASYS with quadcore and performance to match would be awesome

affraid that they'll have to replace almost every other hardware piece in it as well then

Now that many people's warranties are expiring, who will be the first to mod their OASYS?

Maybe upgrading the CPU and overclocking it? The current motherboard already has overclocking settings in the BIOS - just connect a keyboard and see for yourself

I wonder if the polyphony limit is hard-coded in the software, or if it increases with increased CPU power. Not that I need more polyphony- just curious.

I think polyphony is for the greater part determined how the software functions. Ofcourse the used hardware will determine if the software has enough room to accomplish what it wants. But simply throwing in a faster processor will not do anything until the software is made to use this extra bandwidth I'm guessing.

Ofcourse the question remains as you say - is the software scalable enough to take advantage of better hardware. I'm thinking that the right answer is complexer than a few lines

What probably would be interesting is being able to have more memory than 2Gb

.... Hmmm a new mainboard and proc ...

You will loose system stability, without any gain in polyphony by overclocking your Oasys. I'm quite certain the polyphony limit is set in software purposfully more or less, based on the current hardware. Besides, who wants to hear all of that fan noise you would need to compensate for overclocking?

Respectfully,

Andy

Mike - this is significant - EXTREMELY significant. Woudl you be prepared to discuss how this can be achieved in general so that other OASYS users could comtemplate this upgrade?

Any sort of comment from Korg on such a possibility would be extremely welcome also.

Thanks,
Kevin.

Wow that's similar to my piano's polyphony

Swapping out the motherboard probably wouldn't work. The current software is compiled to use only certain drivers - one example would be for the video chipset. You'd need a motherboard with the same chipsets, but then it wouldn't be any better than the current motherboard

I think Mike is referring to his pc.

Sorry folks. This isn't true.
