EdiusNX card (PCI-X) eating up Ram?

[Zorro]

I have a machine here based on an Asus P5WDG2-WS Prof board, 4GB ram and running WinXP-SP2. Of course, Windows can only use about 3GB of memory after a fresh install. After installing the EdiusNX card (PCI-X version), the usable physical memory drops to 2GB?! As far as I understand Bios reserves memory space for expansion cards so why would my ram drop to 2GB anyway? Hopefully someone can explain this behaviour and find a solution. TIA.

Don't have an NX card myself but the DVStorm2 card assigns itself so much memory from the RAM depending on the buffer setting. Maybe this does the same?

Works fine here (see my specs). I have about 600MB in use after I launch Edius and load an NX project.

I go from 1729196 available to 1523292 after opening a project.

Sorry guys, I did not make myself clear: I lose about 1GB of ram by simply plugging the card into the machine! There's no driver installed, no Edius either. Any clues?

[skier-hughes]

I'm afraid I'm not going to uninstall and reinstall just to test that for you :)

[jonandmarkuk]

Something doesn't sound right? Could it be the board as I have not seen anyone posting similar problems.
I would think Windows would be responsible for allocating the memory?

I normally add a 3GB switch to boot.ini

however on the last system i built with NX, it fails to boot with the 3GB switch, so I had to boot in safe mode and delete the switch

I am not sure about the exact cause yet, the 3GB switch has worked on may other PC's

[Zorro]

Anton, even with the 3GB switch I lose about 1GB of physical memory when plugging in the EdiusNC card. Hopefully someone from tech support can help.

Can't be right as the minimum specs for NX is 1Gb of RAM at that you would have nothing left to even get Windows running?

Having only an OHCI and DVStorm with 2GB total system ram I get the following free memory:

Window XP SP2 start up: 1.75MB Free
Blank Edius project DVStrom with Buffer=160: 1.58MB Free
Blank Edius project OHCI HD Buffer=512MB: 1.04MB Free

Update: disabling onboard components didn't help, either. After the NX is plugged in I lose 1GB of Ram in XP. Weird...

Zorro,

How did you check the RAM usage without even installing Windows? You state you just plug in the card ... but, how do you check the RAM usage then? It might not be the NX card - but your motherboard. The BIOS assigns address spaces mapped to RAM for DMA (direct memory access). Is your NX board PCI 64 or PCI-Express version?

Please read my first post, also:

Look for Memory Hole or Memory Remap functions, usually in the BIOS setup somewhere.

Sometimes you have to turn it off, sometimes turn it on, sometimes turn to Hardware, sometimes turn to Software.
