xw8400 specs show dual Quadro FX 3500 support....but how?

Hello

 

I have a HP xw8400 Workstation that I recently purchased when it came off-lease.  In many of my serarches here on HP and other resellers, the system lists as being capable of handling two of the nVidia Quadro FX 3500 video cards.  I have one installed now and the documentation seems a bit vague as to where a second card should be installed.

 

Also, I am running Windows 7 64-bit with 4GB of RAM.  It is running very nicely despite not seeing any "official" support for Windows 7.  Why might that be?

 

Thanks in advance.  These are really a nicely built system and can be had for an incredible price these days.  I plan to use mine for CAD software.

Paul,

 

This Technical Reference may be helpful.  The motherboard shows two PCI-E x 16 slots and one is designated for video.  I have seen some workstation models where the second PCI-E slot is only x4 verses the primary slot being x16.

Thank you for your reply.

 

I have one card in the Slot 2 (PCI Expess x16) which is what that manual specifies for the video card

 

It looks like Slot 4 (PCI Express x16 (x4 performance) J31) is where the second would go, which was the hunch I had.

 

My worry was the power draw of two cards, since in one of the other PDFs I had read indicated caution with high powered cards

 

Since I found so many sales pamphlets indicating support for two cards, there HAD to be something indicating how two were setup   Smiley Happy

The specifications for the xw8400 indicate a 800 watt power supply.Smiley Happy

 

 

Personally if this were my system, I would consider one big video card.  Quadro has some extremely expensive video cards for professional applications.  For gaming, I would pick a consumer level video card.

 

Review the ATI and NVIDIA performance specifications. Look at the memory bandwidth specifications and the DirectX level support.

Two questions....

 

FX 3500 works great....Im curious if its worth going up a notch there (SolidWorks)

 

I have the Dual Xeon 3ghz CPUs.  To upgrade to two Quad Core processors would be close to $900, but 8 processors.  Wow.  Worth it?

Your application(s) need to take advantage of all those processors.  Start Task Manager --> resource monitoring and leave Task Manager running.  Then start your application(s) and run them hard for a while and then switch back to Task Manager.   What do you see for processor utilization across the four processors?  What about disk I/O activity when running your applications?
