RAM IS NOT THE SAME THING AS HARD DRIVE! Read what I wrote above if you're not blind! RAM does NOT have the file system formatting like hard drives, so it doesn't lose capacity! 3.25 GB IS AN ARTIFICIAL SOFTWARE LIMITATION!!!

Any critical things when opening the Kronos? Or straightforward unscrewing all the bottom side screws without any problems?
How many memory slots?


2 slots Wink


MY METHOD:

UNPLUGED your KRONOS Very Happy
WARNING
1) Return your KRONOS, and move it on 2 sweet pillows (for example), 1 for the right side / 1 for the left side. Please, apply a particular attention to the cursors and at the joystick.
2) the screws located under the keyboard are holding an aluminium bar, attention when you unscrew the bar go down
3) unscrew all screws before remove the bottom cover in aluminium
4) locate and remove the original 2GB memory stick
5) put the 2x2GB memory sticks
6) put the cover and screw some screws
7) put in place the front bar and fix it with the screws
Cool PLUG THE POWER CABLE and Power ON your KRONOS
9) Go to the Global menu Page and verifying if you have 3.25 GB Question

Patrick
Just to clarify, incase I missed it , did you fit 4Gb into just one slot OR two 2Gb (one into each of the two slots)?

I wonder who will be the first to produce a YouTube vid of the procedure?

That procedure sounds very daunting...its was easy to do on the Oasys. I dont think I would want to remove 10 screws and deal with falling bars lol, and what not. Plus, I've ordered an 88, so how many screws will be on the larger unit?

The 3.25 gb memory limit reported by Kronos is due to the Intel x86 architecture. It has nothing to do with the OS. Some of the memory address space is reserved for I/O addressing just like any other Intel based PC.

It doesn't matter if real memory is installed or not. Real memory sitting in the I/O address space can not be used by applications.

A 64 bit OS is required to address the full 4 gb of memory. The I/O addresses are moved above the 4gb line. And then if you can fill that entire space with terabytes of memory there will still be some memory that is unavailable due to the I/O address hole.

It would be nice if Korg and others would upgrade to a 64bit OS but that takes a great deal of work and they are building synthesizers, not databse servers so it may be a while.

x86 architecture has little to do with it.


If that were true, 16-bit systems (i386) would've only be able to allocate up to 64 KB of RAM. But 386 PCs back in the day could use up to 16 MB of RAM.


Physical Address Extensions. That's all there is to it. Vista/Windows 7 32-bit Server has PAE, and can see and use more than 3.25 GB of RAM. It's not necessary to update Kronos' OS to 64-bit. Just add PAE.

Actually the x86 architecture has everything to do with it.
x86 requires 700+ megabytes of address space for mapping io devices, PCI etc, into. If your Northbridge supports it and the memory controller can address 8GB then you can use PAE to map the io above 4GB and potentially use PAE to get the full 4GB of usable memory. The OS and drivers needs to be able to support this though, but I see no reason why Korg would go through the trouble of adding this to the test matrix even if all their code were to support it.
I'd rather see them spending those resources on modernizing the sequencer if it was up to me...

x86 architecture has everything to do with it. PAE is basically a hack to address memory above the 4gb line and there are serious limitations there. Its like having a memory based page file. It has to be mapped into the address range of the cpu.

Yes, maybe PAE would be good enough for streaming samples but it is an outdated method of mamaging memory.

The old 386 processors and DOS and early Windows used EMS and XMS. to get around the 16 bit limitations.

Anyway ... this has brought back bad memories of fixing Config.sys files Very Happy

I'm sure it would be a miracle if Korg condones this memory expansion procedure in the first place, let alone re-do the OS to 64bit to accommodate 4Gb. I would like to know what Korg thinks about this; surely they must have anticipated it?
