Live performs better on a quad than a dual. I know this, as Im running both of them and the performance difference is obvious. When I look at the performance monitor, Live is definitely using the 4 cores.

Even if youre not maxing out the specs of the Nehalem, it doesnt mean its a waste of money. New hardware usually takes years to reach its potential. I would bet a real world test will show that an i7 will run the Live performance test better than a Q quad. It has about a %30 performance benefit compared to the Q series clock speed, Ableton shouldnt be any different.

There are quite a few people on here running Live in a 64 bit OS, and very happily as far as their driver support allows. Which repeatable problems are there with Live on x64? Im toying with the idea of moving up myself at some point.

Only 2 gig ram able to be accessed per app? How did Liam Howlett ever make those amazing sounds using workstations whose sample sets topped out at 760k?

In my case, I certainly cant point at the computer as the bottleneck for my creative output! Its the thing between my ears that doesnt have enough bandwidth.
I would LOVE to see real test results myself. It's abundantly clear that Live 7 supports 32bit multi track recording, but does not support 64bit multi track recording. Everything else is a mystery to me and I mean that emphatically. All I know is that I was told matter of fact that Live had distinct problems in 64bit. I have never ran a 64bit system and was seriously looking at purchasing an i7 professional rack mount computer.

The tech person that I was talking to at this same company steered me away from the i7 by stating that Ableton has REAL issues in 64bit. He also made it clear that Live could not make use of the i7's unique internal systematic process with respect to a real performance increase over the Q series processors. He also stated that Ableton's software was unable to provide access to any more than a little over two gigs of ram while operated in a Windows OS. Whereas most other contemporary DAWs had made modifications to their written driver support that allowed for a much broader ram access diversity, Ableton has not at this time.

pants (and everybody else), listen to me, I don't KNOW shit and I'll be the first to make that abundantly clear. I am just relating what this tech made clear to me at ADK. Ableton is, and will most likely always be, my DAW of choice. It's the greatest audio design tool I have ever used short of my life long love affair with 4 strings and some electricity. That's why I decided to build a system that will best support it in 32bit, and can clearly and evidently move on to 64bit when Ableton either (a) officially is 64bit supported, or (b) I am confident that it will run 64bit from my interface to my monitors without any problems.

I will state that I am a little leery to buy the idea that an i7 can provide any real benefit to a 32bit user. I don't think it ever will be. I mean, why would it? Nobodies going to make the effort just to back pedal their software support to 32bit users because the squeaky loop gets the goop. I have to believe as you pointed out, that the the idea is to move FORWARD into the realm of the 64bit supported application.

What would be just as fascinating concerning this 64bit question, would be:

What is REALLY happening in Ableton Live when a user *is* running Live in V64? I mean, how many of the forefront functions and manipulations of Live are being accomplished (fully facilitated) by real 64bit support? Are sample access speeds faster and more cpu efficient? What about plugin support? How does that much work?

Does Reaktor when used as a plugin in Live actually benefit via the 64 bit platform?

As far as the i7 is concerned: What about efficiencies with respect to exponential voice computations?

Ever worked with Stylus RMX?

Wow! I just thought of something. Doh! I should be asking Eric about this stuff. He would know.

MR. Owl, how many licks does it take to get to the center of an i7? :?

I'm just afraid his answer will have something to do with Logic and a Mac :lol:
No application under a 32 bit OS can use more than 2 gig of Ram. Its nothing to do with Ableton, its an addressing limit. Im not even sure if it applies to things like Stylus, are they running in Live's address space or their own?

anyone?

are you sure any of this matters? Have you come across any situation where a RAM limit of 2gb has hampered your creativity?

I only raise this, as you seem to think these issues are crucial to your purchase, when I would see them as marginal at best, and a distraction from the end goal ie making music and learning your craft. As much as I love chewing the fat about hardware, you can get lost in it pretty easy and it becomes its own pastime.

You cant go wrong with the Q6600 or similar at the moment. Fast, overclockable like buggery and pretty cheap.

I might be wrong but it seems your mixing things here. The bitrate of the
recorded audio has nothing to do with the operating system bits.

That's pretty much precisely what I am wondering about.

Nothing at this point is honestly stopping me with respect to my purchase of a new computer. That's done.

What I want to know or understand better, and I will thank you now and let you know in advance that I am very grateful if you are able to help me to better understand this 64bit confusion.

I also know that the i7 will run Live with no hiccups. HOWEVER, I was "informed" that the i7 with respect to Live is presently over kill that does not benefit the user in a 32 or 64 bit OS because of Live's architecture. I guess this has something to do with the way this process handles samples. The tech said that this was not the case with Cubase, Sonar, etc. an that they were dramatically improved with respect to their current capabilities using an i7.

He also related the fact that so much is changing so quickly with respect to the i7 CPU development that it would be a waste to get one presently anyhow. There will be i7s out in the near future that will completely dwarf the present entry level CPU capacities/speeds.

but getting back to the 64bit thing which is what I am VERY interested in.

Could I ask a few basic 64bit questions directed at yourself and adventurepants that will clear up tons o confusion for myself and others?

You state that recording clips in 64bit and an application such as Live being processed within a 64bit OS are two completely separate things, correct?

How/why in a basic sense please?

I honestly thought that recording in 64bit would be the biggest audio benefit of all.

Live also utilizes what is referred to as a 64bit mix summing and audio engine.

Does one have to use a 64bit system to reap the benefits of this?

When live 7.0 is used in a 64bit windows system, what are the performance advantages as opposed to XP 32bit? Obviously this scenario would include identical processors in an a/b comparison.

Does a 64bit windows run application have greater memory facilitation/access than a 32bit app would? If so, how much?

Thanks for being here for the dumb of head and the hopeful of heart. :)

I'm running Live 7 on an i7 with vista-64 and an M-Audio 610 with no problems. The only issue I've run into so far, is that I had to disable Gigabyte's power saving feature because it was causing glitches in audio (all audio, not just in Ableton).

So far, live is only a 32-bit application and so can only access 2 gigs of RAM. The nice thing on a 64-bit OS though, is that it can use a FULL 2 gigs, since it isn't competing with the OS for the same address space.

If you really need Live to be able to access more than 2 gigs of RAM, you could probably set up a RAM disk and copy your samples and tracks to that before starting Live each time. Live would see it as just another hard drive. I haven't actually tried this though, as I haven't run into any RAM limitations yet.

I'm hoping that Ableton starts officially supporting 64-bit platforms soon, even if the application itself remains 32-bit.

The bits of an operating system kinda tells how much info
can be pushed arround with a single clock (the cpu frequency)

The bits in audio tells how much info is stored with
each single sample (samplerate) Another way to put
it is how detailed each sample is.

64bit audio isnt really practical. Do your stuff in 24 bit which give
you a massive 144db dynamic range. If you need more than that
you probalbly should be solving other issues.
Live also utilizes what is referred to as a 64bit mix summing and audio engine. Does one have to use a 64bit system to reap the benefits of this?
No - Think of this as live has a summing engine with 384db dynamic
range.
Does a 64bit windows run application have greater memory facilitation/access than a 32bit app would? If so, how much?
If you run a 64bit application in windows7 64bit - I believe it support 128 gigs
of ram. Any program run on a 32 bit OS would see about 3 gigs.

just clarifying that last point. Any single app in a 32 bit OS cannot address more than 2 GB Ram. The OS itself can address up to about 3.75GB in total depending on configuration.

It just blew my mind thinking about the hard drive space needed for 64 bit Audio!

But still in yet, it leaves the following curiosity wide open:

If a single 32bit application is limited to addressing 2 gigs of ram, how much can the same application address in a 64bit application?

As you state, 3.75 in a 32bit OS for the over all operating system's max and 128 (holy architecture differences!) gigs in 64bit...

but how much of the 128 gigs of ram in a 64bit OS does the single application have access to?

edit: I just read up where it is stated that a 64bit OS (Vista) can access 1024 gigs of Ram, one TB . (Holy shit!!!), thus, is Jan stating that a single application has access to 128 gigs of ram (!!!???)

holy crap this is outta control! 8O

2^32 = 4gig address space. I wouldn't see why an application could take up 3gigs or so of address space. Why would an OS prevent an application from taking up unused memory?

Anyway i haven't read through this entire thread. I can say as a q6600 and a dual monitor user I am very happy.
Live 8 even sizes correctly, Live 7 unfortunately u have to drag across the 2nd screen everytime you start up.

The amount of ram avalible on 64 bit vista is different for
each version. Home, ultimate ect. I dont know excatly what
amount of ram is avalible to each application. But I'm pretty
sure it's so much that we need not worry about that !

The following is very recent researched feedback. I cannot really take credit knowing that I just learned this 5 minutes ago.

The ram access limitation is in the application itself. If it's compiled for 32bits then it can only access 2GB of RAM, even when used in a 64bits OS on a 64bits computer. So to utilize more than 2GB of RAM you need to install a version that supports it. (Live does not at this time, Live 8 may)

If a program app. is written in 64bit, the following are the RAM access allowances in the various versions of Vista (as Jan said)

Home Basic: 8GB
Home Premium: 16GB
Utimate: 128GB
Business: 128GB
Enterprise: 128GB

In a 32bit OS, you can achieve a 3gig ram access but the following must be considered:

3Gb comes into play only for large address aware applications - and they have to be compiled that way, also in XP your system has to be booted with an appropriate flag.

In 32 bit Windows OS-es a process by default can address up to 2gb of memory, the rest of the addressable memory is for the kernel and device memory. So if you use that aforementioned switch which enable LAW applications to address 3gb you take away memory from your system - that's why you have to be careful with it.
