I hope someone here is familier with the DC7100 made by HP. Its not a flash machine but it works quite well as a media centre. Searching the web everyting seemed to indicate that it has a 16x PCI-E slot, so I went ahead and bought an MSI HD2400PRO due to it being low profile and passive. It requires no external power which was good too.

Crunch time. It doesnt work. With the card plugged in, the onboard vga doesnt work either. Unplug the card and the onboard vga springs back to life.

My question is, if anyone knows this system and has tried any PCI-E graphics cards in it, have you had any success? If anyone can be bothered to google the specs of the machine and see anything glaring that I missed as to why it wouldnt work I would really appreciate it.
 
Ill take it to work tomorrow to try in other machines but they are all HP workstations, DC530's or D530C's. Next step is to take it to a mates place to try in their machine. If all that fails I guess then it is a bust card. Rather have a bust card than have the machine not accept any PCI-E card.

Just found the manual for it on the HP site and under the specifications it says PCI-E Slot 16x: 1(2)(3) and under the (2)(3) sections states:

[2] Accepts low-profile, reversed-layout ADD2/SDVO card: height = 2.5 in., length = 6.6 in.
[3] Slot not accessible in configuration using PCI riser card.

Now looking at what ADD2 and SDVO cards are they seem to be DVI cards, but nothing fancy. My question is is this the only PCI-E card this machine will accept? I cant understand, if its a PCI-E 16x slot then surely any card should work?

Seems to me that those are just guidance for the card's profile so you can fit it in the case, not anything technical.
On the other hand I just read this on Wikipedia:
Wikipedia said:
The second generation ADD2 cards are PCI express and employ a standard interface. There are, however, two distinct flavours of ADD2 cards: ADD2-N (normal) and ADD2-R (reverse). "Normal cards use the first channels on the PCI-E connector while Reverse cards use the last channels." The ADD2-N cards are reported to work without fuss under Linux with Intel chipsets ranging from the 915 through to the 965.

Now this would obviously make quite a big difference, would it not?
 
Yes that would make quite a difference, I wonder if that applies specifically to the ADD2 cards or any PCI-E card you stick in the machine. Ive been reading all documentation I can find and it appears that in the manual it states a RADEON X300 as compatible so I dont really see what difference anything else would make, but Im not that technical to know.

Oh weill I am going to try the card in work machines tomorrow and in a mates machine tomorrow night. I am really hoping the card is borked as I wanted the 2400 for its hardware accelleration of h/x264 and vc-1 material!
 
Seems the card works in a machine at work but using the VGA port, dont have DVI here to test. Leads me to believe I have a faulty dvi - hdmi cable. Only problem is now when trying to run anything 3d or even run videos the machine crashes. Thinking might be power related. *sigh*
 
Yup just round my mates place and tried it in his "proper" machine (p5b deluxe, e6300, corsair hx520 etc) and it does the same thing. Crashes as soon as you try do anything 3d. So its going back tomorrow! Thanks for the help and ideas guys :)
