Extreme PCIe – Dualcore Setup not getting it’s full power!

[Luke Maslen]

Hi,

Please try temporarily uninstalling the DeckLink drivers and removing the card. Now restart the PC and see if Windows can see all 4 GB of RAM. Also try some renders in Premiere Pro and see if there is any difference in performance. When you have completed your testing, reinsert the DeckLink card and then reinstall the latest DeckLink drivers.

In my experience the 32bit version of Windows XP Pro will not use more than 3GB (from 4GB of RAM modules) no matter whether you have a PCI-Ex Decklink card installed or not. The motherboard supports it because different operating systems (eg Linux) support >3GB, but you will probably have to wait for Decklink drivers that run under the 64bit version of WinXP Pro before all your 4GB of RAM gets used.

As for the Premiere Pro rendering only using 55% of CPU resources, I think some effects are only single-threaded so can only use one core.

thanks guys.

well, luke, i have been seen this problem (3GB limit) before the installation of the card…I guess it’s a Windows Xp issue…

But what about the premiere processing getting only 55% of it’s power. it’s really annoing. I’m using only PPro built-in effects like color correction etc…(when PPro are booting there’s a text telling me that PPro sees Multiprocessor)
**(is this color correction effect realtime if the DL card?)

cheers
and thank you guys for the replies.

I’m pretty sure it is a premier pro issue, i’ve got two xeon nocona processors in my system with hyperthreading so It looks like 4 processors, and even when rendering heavy effects in premiere I rarely get above 25% cpu load. I’m not sure if it is because of multithreading, multiple processors, or perhaps the windows CPU monitor doesn’t calculate load correctly, but this is normal. I have no idea if it is a true measure of performance or not.
