So when are you going to upgrade to DP8??

Sorry, with 383k posts and 43k topics on the board I don't always get to see each one. On top of that, troll hunting season just opened up this week.

Thanks for the link in the subsequent post to Frodo.

Any links?

Sorry, Future. I didn't notice your post. Same article, too!

I have a Core 2 Duo Mac that doesn't support the 64-bit kernel or 64-bit EFI. I have 9 GB of RAM. I opened up Kontakt 5 in standalone and loaded it up so it was using around 8 GB. It ran fine.

I'm growing more and more toward believing that it's going to run just fine in my Mac Pro 1.1. Too bad we can't find out for sure until March, but at least we're getting closer; just a month or so away. We've been waiting a long time to get to this point.

Both Kontakt and PLAY have found unique ways to get around this limit. That is not the normal default, from what I understand.

They did memory servers so you could use an additional 4gb in 32 bit, yes. But now when the memory servers are 64 bit they can use your full ram. And when the hosts go 64bit they can use all the ram and the memory servers will be redundant. Even if you have 32bit kernel. Please read the article I posted, it makes everything very clear.

+1
correct, these both have memory server technology built in to the app.

Because kontakt has its own memory server.

Doh! Damn you KG!!!

People! The Kontakt and PLAY memory servers can use more than 4gb of ram because they are 64bit apps!!! Not because they are some mysterious special thing. When the memory servers were 32bit they could only hold 4gb extra... And when the hosts (DP8 comes to mind) go 64bit the memory servers will be redundant...

Okay. I just pushed Firefox beyond 7 GBs. Everything is fine. Does that count?

I did read it, or rather skimmed it, to find the appropriate parts. I guess I am still doubtful, since not every article is necessarily true.

But since I don't have any alternative documentation, I will stop interjecting with my position, since it is possible that you are right about this. It would be great for everyone if this is true. Even though I have the ability to boot in 64 bit, there could be reasons, at some point, why I might prefer to boot in 32 bit if I didn't have to give up the extra memory that DP can access.

However, it really would be great if someone who uses Logic could do a memory test in 32 bit. I have heard that Logic users have not been able to get above the 4GB cap in a 32 bit kernel, even though Logic is 64 bit. You'd think Apple would have figured out how to make Logic do that if it could be done. But maybe my information is not quite right.

And anyone using Bidule in 32 bit should also be able to do an experiment for us. Just not Kontakt and PLAY, because they found non-standard ways to do it. Though it does suggest that it should be possible for a developer to get a DAW to do the same thing if they worked at it.

This is all very interesting. I'm feeling a sense of suspense...

I really do like simplicity in that argument! Seriously... I like it.

I can investigate this statement a little, and might be able to provide some additional confirmation from one of those developers. But it might take a couple of days.

That does sound promising.

Interesting article FL and I'd be thrilled for everyone if it's indeed correct but it contradicts everything I have ever seen about the 32 bit kernel Ram limitation vs 64 bit kernel architecture.
But until we have confirmation(DP8 in our Macs) & actually working in our respective systems we are all speculating.
I talked to Motu tech support more today, again explaining the 64bit questions everyone here is perplexed with and the tech I talked to today mentioned that a couple of them were discussing this and agreed someone from Motu should come here and bring some clarity to the subject at hand.
Hopefully someone who actually knows about this besides users gleaning info from sources on the Internet can give us authoritative answers,then we will know what's actually possible & whats not.
There is also a computer builder on GS that also happens to be a Mac reseller, ADK, he happens to be one of the most knowledgable people I have seen on the web.I think I'm going to start a thread there and see if can get an answer from him or someone else that really know about this.I will also start a thread on VI-control there are some developers posting there that can give us some answers.
We shall see.
