I am reading a number of statements in this topic that worry me. ....

peter, you are fairly right from the point of view of a programmer, although even this is not the whole story.
i've mentioned before, W95/98/ME manages memory not in the same way as W2K/XP does and i'm sure, nobody would be interested in an excurse regarding page faults, stack, heap and similar.

the term *virtual memory* is commonly used for a swapfile, even MSDN (microsoft developer network) is telling us: *Virtual memory is the space on the hard disk that Windows 2000 uses as memory* and the wording in the taskmanager is quite the same - so i think everybody understands, what's meant.

fact is, that many users would be happy to use _more_ than 1GB, which is not resp. hardly possible with 98 (besides other issues with this OS, i don't want to expand here - you have mentioned one)
unfortunately the same with most (nearly all) W2K/XP installations - but not because of the operating-system or memory-management but because of the design of the endless-wave-engine (developed by rockwell 1996 for modems, iirc)

i will be happy to discuss with you further details via PM
christian

Thanks for the advice so far, but no further forward I'm afraid.

First I tried setting the virtual memory to 'No page file', which didn't help at all, then I tried, as suggested by CM, to set it to 512mb. This also has not allowed me to load any more samples. GS still shows that I am only using 78% of the memory. In the task manager I have over 500mb of physical memory free. msg32.exe is only using 639mb.

I will, if necessary, try running Win 98, but I don't see how this will help from a RAM point of view. Obviously 98 runs in less RAM than XP, but in theory, XP should have a whole 512mb to use, in addition to the 1Gb that GS should be able to reside in.

TASCAM are not replying to my registration data when I try to send it to them, so I don't have a reg code, so I can't download the public beta of GS 2.53 to see if that remedies the problem. [:(]

As for the type of motherboard chipset.. I'm not sure about this. The machine is a Matrix from these guys... http://www.meshplc.co.uk/

well, the struggle continues...

If you installed GigaStudio from the discs you got in your package, you may have severe problems. For XP, you need to install the version on the website...which is a full installer, not just an upgrade patch.

This may be the root of your problems. XP in and of itself is not unstable with Giga in the manner you describe.

The version on my Gigastudio installer disc is version 2.50.48, which is, according to the www.nemesysmusic.com website, fully compatible with XP. I have not installed version 2.53.00, which is labled as a public beta patch. I have not installed this for 2 reasons. Firstly, I have not been sent my registration / download codes, so not only can I not complete registration of my copy of Gigastudio, I also cannot download updates from their site. Secondly, I am wary of public betas as a rule. But, I would install this one due to the problems I am experiencing.

I don't understand what you mean when you say that there are no instability problems 'in the manner I describe', as there quite clearly are!

I'm not making this stuff up. [:)]
I wish I was.

Your version is a good version.

What is your system configuration, including make/model of audio interface? Something is fishy. I'm not implying that you're making anything up at all. However, the behavior you're seeing is not typical, and there could be some issue with your setup which is causing the problems. Perhaps we can find it...

Bruce - it would be excellent if we could find it. [:)]
At the moment I'm very close to being able to run all I need in real-time on one machine - clawing back that 20% of memory would completely nail it.

The system is a Mesh Matrix XP 2200+, with an AMD XP 2200+ processor, running at 1.8GHz. 1.5Gb of DDR RAM. 2 HDs - One 40Gb system drive, One 200Gb audio drive, where all my .gig files reside. When running GS, it is the only program running on the machine, besides the VSL performance tool.

The midi interface is a Midiman USB Midisport 4x4, using the latest driver from the M-Audio site. The audio interface is an M-Audio Delta 44, which GS assures me is GSIF compatible. I'm certainly getting solid, pop-free audio, and 160 voices of polyphony. Again, using the latest driver from their site.

Hope that info gives you some ideas. I'm pretty much stumped....

Interesting. I've taken out one of the 512mb blocks of RAM, leaving me with just 1Gb. Now, gigastudio can load fewer samples than before, as would be expected. BUT, the 'memory' indicator is at 99%. Could it be that my problem lies with inaccuracies in GS's memory indicator? I can load more samples with 1.5 Gb of RAM installed, but GS's indicator says 78% at 'top-out' time, when it maybe should be saying 99%. So, with the full 1.5Gb installed, it looks like it is recognising the RAM, but not specifying its usage correctly in the memory indicator.

Hrrrrmmmm. I wonder. It still doesn't explain why my task manager says that I have 500mb physical memory available when GS says 78% full and doesn't let me load any more samples.

[Edit: Just had a look in task manager again. After having put back the 512 block to take me up to the full 1.5Gb, Gigastudio only uses 100mb more than it did before the block was put in. Not ideal.]

I agree with Peter Roos that Windows98se seems to run more samples than XP. A friend of mine tried both systems as an experiment with 512mgs of RAM and when he loaded the Gigapiano under Win98se, it took 12% of memory in Giga. Under XP it took 18%; we therefore concluded that since Win98 takes less RAM we can load more instruments and samples under Win98. Peter, can you tell me how to get to the "system.ini." file settings as every once in a while I get a blue screen message when quitting Giga telling me my system.ini. settings need a minimum stack of 5 pages. I haven't been able to find where I can change that but I'd especially like to set the vcache settings to what you specify. Thank you!- Frank

Wow, Frank - 50% more memory under XP!! That's insane.

Nothing for it then. Tomorrow I install Win 98. XP can go to hell in a handbag.

[8o|]

I've had an abysmal day today.

Boys,

this is simple maths:

1. As XP needs at least ca. 210MB for the OS, it is no wonder, that with 512MB RAM, you are able to load more samples under Win98SE, which will (e.g. with 98lite) only occupy ca. 80-100MB of RAM.

-Win98SE: 512-100=412MB for samples
-WinXP: 512-210=302MB for samples

2. Since Win98's VMM will refuse to boot with more than ca. 1000MB of RAM, we will be able to load up to 900MB max. under Win98SE - no matter how we set the vcache and/or limit the PhysPage. XP allows you to put in e.g. 1,5GB of RAM and when you have configured your system according to the TASCAM-guide, you will be able to load up to 93-98% shown by the GS-memory-meter, which equals around 1Gig for msg32. Lower results may occur and are part of the holy plan of the universe [;)].

-Win98SE: 1000-100=900MB for samples
-WinXP: 1500-210=1290MB for samples/limited to 1000MB max.

Conclusion: You will be able to load MORE samples using XP, in case you are not one of those "poor boys" that can't get their XP-system to load the max. Shit happens [:(].

So for me it looks like this (my experiences are based on Asus boards with VIA chipsets, Athlon processors and Maxtor drives):
Under Win98SE I always get intermitting glitches and or choking streams, whenever the polyphony is topping 140 mono voices. The same hardware under XP gives me rock-solid 160 voices; no glitches, no choking. And around 100MB of RAM more for samples. Under Win2000 I was not able to load more than ca. 600MB before the "message of death" <error 5> has been shown. This is at least what I experienced in the past year and I am sure, that other hardware might give you different results...

All the best

Roman

Hmm, that's a fairly patronising tone you have there Roman, boy. [;)]

Spoke to TASCAM tech support earlier. They reckoned one thing that has (perhaps inexplicably) solved this problem in the past is a reinstallation of XP, which I might try before I go back to 98.

Was just reading through this topic and remembering the days of 98 before I upgraded... and all the crashes. All my machines run XP now, and each one has 1GB or more ram. The one recently added to run SI strings has 1.5GB, and right this moment I am looking at it at 98% full in GS. There must be something odd in the combination of gear that is preventing your machines from running correctly, and I would suggest further reseach into the matter before returning to 98 (cuz getting it to work is SO worth this time both for memory and stability purposes.)

All the machines that run GS here are built the same, and all components were chosen based on a prior system that seemed infallable on xp. I always steered clear of AMD simply because of the difficulty in making certain all components were compatable with one another. It IS far less expensive and just as fast to go AMD instead of Intel, but the difficulty in choosing totally compatable parts scared me off and made me stick with Intel. These machines were not designed to be gaming speed demons or anything, just fast, stable giga machines that could handle what I threw at them. Perhaps I've just lucked onto a good combination, so I'll share:

(all machines) - Asus Mobo P4B
(all machines) - P4 2.0b (2Ghz) (400mhz fsb)
(2machines) - 2x 512MB PC133 SDRAM Samsung ram (1GB total on each pc)
(1machines) - 3x 512MB PC133 SDRAM PNY ram (1.5GB total)
(2machines) - M-Audio AudioPhile 2496's
(1machines) - M-Audio Delta 44
Maxtor HD's all (4x 45GB, 1x 60GB, 1x 80GB)
Using MidiOverLan for midi connectivity
Midi input from Roland full size to Midiman Oxygen 8 and then in via Oxy8's USB cable.

All 3 run on XP, and have been running like this for many long months now without any having crashed on me for any reason even once. Then again, I almost never even turn those machines off. I like em ready when it's time to work [:)]

Anyway, I guess the point of this post is just to say that it IS very possible to run GS solidly on XP and make full use of all your memory, even up to 1.5gb. 98 would probably be a step in the wrong direction. On the other hand, if that ends up being the only way you get that machine to work, then by all means, do it so you can get back to making music! [:P] Then build an XP-friendly machine later on.

Seriously, good luck with the comp, Chompy. I've been there myself and hated life for a while.

'xcuse me, Chompy, good lord - NO! I never intended to sound "patronizing", I rather loved to sound "petrifying" or even "paralysing" [;)]. - No, honest:

Sorry, dear. I really don't wanted that. I went ill yesterday and was in a somehow rude state. I know how it feels like, when you just can't get your gear running in an acceptable way; noone wants to be told then: "Hey, you poor su**er, look at me, it works great at my place!!" I didn't want to sound like that. To maybe give you something back:

Besides stability and performance there seems to be an issue under XP, you won't experience with 98SE: a loading slow-down someone over here already mentioned. It occurs on my systems at around 80% of load. Whenever I try to load a giga-instrument , which is part of a large sample-pool and doesn't use the whole lot of them, the loading starts to snail and takes minutes. The CPU-meter of the taskmgr slows down (usually the CPU shows a high peak after short while transfering samples to RAM before GS is done). The only way to get around this, seems to load giga-instruments that really take the whole pool, e.g. a full-version-piano. I successfully separated giga-instruments out of a large gig-archive (the ".gig" file explorer shows you) using the editor and the "save limited/check unreferenced samples"-function as a workaround. Such separated giga-files with only one instrument contained usually load fast even under high-load conditions. As I have been checking this out with Tom Hopkins, it was nice if someone over here would add his/her experiences regarding these slow downs. But I am going to get OT, sorry...

What I wanted to say is: if you can't manage to get XP to give you an higher load and if you can get your system running well under 98SE, it might not be the worst thing to do, despite the fact that I consider everything MikeG has said to be true. I have heard of many people with very stabil performance under 98, too. But as you WILL have to move to XP as soon as GS 3.0 might be able handle the RAM-limitation, the 98-system won't be your final destination, I guess...

Good luck


The Roman Patronator ||Qo== ......... (large pump-gun)

My apologies also Roman - I wasn't in the best of moods last night at all. [:)]

I would rather stay on XP than 98 if at all possible - especially seeing as (from Mike's post) it IS clearly possible to get past 78%. Just a little gremlin somewhere.

On the AMD / Pentium thing - I would always, always go for a Pentium if I was buying for myself, but this is a company PC, and it's company policy (for some reason) to go for AMD...

Thanks for sharing the 'lucky' spec Mike. [:D]
It's very similar to my own setup, Asus mobo, Midiman and M-audio interfaces. But I notice your RAM is not DDR, whereas mine is... and of course there's the AMD / Pentium difference.

If I get anywhere, I'll post.

I have to agree with what Peter has shared here. I can now say from experience on two different systems that "downgrading" from Win2000 to WinME has literally doubled the number of instruments that I can load. I think I mentioned in another post that addiding in excess of one gig of RAM while running Win2000 actually caused me to be able to load *less* instruments.

Actually, maybe I can try to test this myself again, and install XP on one of my Giga PCs, replacing the well working Win98 setup (with RME Hammerfall). I will first make notes on the memory load of my strings template, etc. After installing XP, I will then add 512 to the already installed 1 Gb. And let's not forget to make a good backup first [:)]

I have become curious again about this stuff.

Cheers,

Peter
trying to start fixing something that ain't broken... [;)]

Are you sure you want to do that, Peter? [*-)]

I know if my system was working well, I'd leave it alone...! [:D]

Just to add fuel to the fire. I have 2 Win 98se machines and one new XP machine....both 98 machines are stable and have been for many months. My XP machine appears to be stable (it's new). All have a gig of Ram. XP will load to 99%. I am loading twice as much stuff into my 98 machines.

Chompy,

I can feel with you! I bought Gigastdio and my first PC 16 month ago. Up to this point I was a Mac only user. Until my first GS machine did work I nearly had a nervous breakdown. It’s only because I know that it can work from other people that I went on. I am by far not such a tech guy as the other members writing in this thread, but I know one thing: Exactly the same configuration - Gigastudio+OS - will work fine on one PC and give much trouble on another. There was so much controversial stuff written about al this that it is difficult to know who really knows all about this. To me the problems are in the hardware (mostly motherboards / how your machine is configurated etc.) I did not get my first GS machine to work until I did change the motherboard. From then on it did work fine without much tweaking. Now I have 2 GS machines which are the same except the motherboard; one works fine with 1.25 GB RAM and the other one does not even start with 1 GB RAM.....Also your drivers - soundcard/Midi interface can have some influence.

Probably the most important thing is to keep cool, because sooner or lather it will work. And then do not touch anymore.....I am not a Mac fanatic anymore. I do have a PC laptop for al my Internet stuff - I am writing on it right now- and I even can use it as an additional GS machine, it works great! But sometime and for some people, getting Gigastudio to work is not an easy task, especially because when you are impatient to make music and get the dam thing to function!

I am sorry to not being able to be of more help, but once more : it will work!

Iwan

A bump to the top for this thread, with some info on a changeover I've just made.

I now have 2 machines for Giga that were both until recently running Win XP. One had 1.5Gb of RAM, the other 1Gb. I took the 1Gb machine and installed Win 98. This has made a huge... vast... immense, nay, collosal difference to how much I can load into Giga.

Under XP I was maxing out my memory in the 1Gb machine, to 99% - couldn't load another thing. Under Win98, with exactly the same patches loaded, I am only using 56% of my memory! I can load a BUCKETLOAD more samples under 98 than I can under XP.

My advice to anyone thinking of using XP for Giga would be "don't do it". This may all get sorted out with v3 of Giga, but until then, 98 is your OS.
