Till now I wasn’t able to use lower latency then 13ms with my Pulsar 2 card. I did all the tweaks I could find on planetZ but there where always some clicks and pops. My mobo isn’t great (asus AVA266) en my processor isn’t the fastest anymore these days (old Athlon 1000) and I only have one 7200 harddisk and 512 MB ram.
Because I use the exs-24 sampler in Logic a lot, I wanted to get lower latencies and was about to buy an asus P4tE and 1800 northwood soon.
Today I disabled virtual memory totally, just to see what would happen.
Guess what….I can set ulli to 4 ms, no problems at all, even with larger projects. (3 ms still gives some pops). I’m amazed, this is really great!
I will test further and see if I really can keep ulli on 4 ms but so far so good.,everything works fine.
Does anybody know any reasons not to turn off virtual memory? (Besides out of memory errors)
However I think I will still buy the P4te mobo for absolute stability and performance but now I can wait a little bit longer till the northwood prices drop a bit more.

can you turn virtual mem off?
very confusing, mmmmhhh
i think i read somewhere to turn off virtual memory somewhere, but then i'm on a mac.
couldn't find it in the 'optimizing audio for mac' topic, i mentionned it, but no one made a remark about it.
could it have been somewhere on a cubase site? don't know. fill me in please.
i'll have a go with it as soon as i find the time.

Mac memory architecture is completely different from Windows and you can turn off VM safely on regular machines today. It might be handy on an iMac with 32 MB though.
The apps have an info about minimum size of the memory partition they run in (you may increase this - and probably will for audio use) and the OS simply takes what's left.

I monitored my memory usage during some time with MemTurbo. I noticed that, right after opening, PulsarOS eats some 64MB for my project. However, after a while, my memory is automatically freed up.On 2002-02-20 08:49, subhuman wrote:
I would NOT suggest turning virtual memory off ever.
I do not want that. I don't want XP to unload 'things'. Whatever they may be, I suspect it's disk cache. Whatever it'd be, I will reopen everything I opened before. And then XP has to read it from disk again.
Does XP writes memory to VM then or is VM also a disk copy / backup of RAM, for stability?
While I got plenty of memory.
Why would I keep Virtual Mem on? Does XP require that? It's turned off on my Win98 machine. Enough RAM there too.
Here's a jpg for a snapshot of MemTurbo. I haven't managed to yet to give you straight image here ;(
Left, you see RAM being eaten by PulsarOS, right it get's freed again, like XP slowly flushes RAM. I knew XP does that, but I rather use my own memory cleaner. When I want to. Quite self'ish huh.

Adobe PhotoShop refuses to open when Virtual Memory is disabled. Maybe some audio programs need VM too.
