Dear Users,
I've updated my Gigastudio with 512MB ram. Now this machine uses 2,5GB RAM. My system prefrences do show this amount, but when I start my Gigastudio (recently updated to 3.2), and run the memory test, it only shows 2.0 GB RAM.
Besides that I can't seem to get the loading above 58%.

I've tried all presets (1 to 4) and the MathiasMemory tweak.
Nothing seems to resolve my problem.

Could somebody please help me a hand and get me on the right track?

Thanks mates

Cal

Forget percentages; they are more or less meaningless within GS. How much memory does this translate to in Task Manager? If it is over 1.1GB then count yourself lucky. If it is less than 1GB you might somehow be able to squeeze a little more.

Thanks mate,
But My counter stops at 889MB
Can I squeeze a bit more? Smile
But how do I do that?
The added RAM doesn't seem to matter at all, because I cannot load any more samples in comparison with the previous installed 2GB Ram.

Perhaps I should reconsider to upgrade to 3 GB?

welcome cal,
a quick rundown for memory usage ... windows devides memory into 2 categories: kernel and user ... the system and the GS streaming engine are using kernel ... a 2,5 GB sytem leaves ~1,25 GB to the kernel ... minus memory usage of system and applications (100 - 250 MB depending on configuration) results in ~ 1 GB left for GS.
as DG mentioned: on an ideally configured system you might be able to get 1,1 GB or even a little bit more.

as a sidenote: you should look into your system specs ... 2 GB RAM sounds like 2 x 1GB, adding just a single 512 MB stick might actually reduce your system performance (eg. if your chipset is using dual channel memory access). also a certain amount of RAM might get lost for mapping PCI-resources and VGA shared memory.

sorry for complicating things, but if not essentially needed i'd look at 900 MB for samples as a reasonable value, otherwise be aware you will have to spend some time on tweaking the system in detail ...

Thank you very much for your extended reply.
I really do appreciate this.

I've been tweaking my machines with the xp-music website.
Do you have any suggestions for tweaking?

-Question:
*when I update to 3 GB does this leave any room for loading more samples or does the kernel not allow you to go above the 2,5?

Thanks mates
Cal

cal, 3 GB RAM leaves (simplified speaking) 1,5 GB to the kernel and 1,5 GB to the user (memory) - i have not heard about any GS system so far able to _use_ those now theoretically available 1,4 GB (1,5 GB minus minimum for windows itself 100 MB).

if you followed the xp-music website i don't have anything to add except: be careful and keep images of a working system before applying more tweaks - IMHO the tweaks on xp-music are already too much (if you apply all of them)

If you can stretch your budget a litte, I'd suggest upgrading to GVI - you'll be able to access more RAM that way. Upgrades in the UK cost as little as £45 (if you're upgrading from GigaStudio Orchestra).

thanks guys for all your help,

How much % of the RAM can we use using the GVI plugin?

Thanks for the tim again. [Wink]

The RAM limit is dictated by the host program, which is (if I remember correctly) 2GB, although this assumes you have 2GB spare after loading Windows and device drivers and the like. If the host is large address aware I think the limit is 2.8GB but obviously you need more than 3GB RAM to have this amount spare for samples after Windows loading (and you'll need to change the boot.ini file).

At least I think that's true...

Don't forget that you can load multiple instances of GVI.

I've consistently overloaded my CPU with polyphony long before ever coming close to running out of sample memory using GVI within Cubase.
