Problem installing 2nd video card for dedicated physx

Hey all, I recently attained a 8800GT for free so seeing as I have a free PCI E slot I decided to chuck it in for physx and mainly something else to work on / learn about.

My system specs are posted in my sig.

The problem i'm having is when I put the 8800GT into my 2nd slot (the one below my 5770 labeled PCI E x8) and try boot my compy it wont post at all, instead the output will be on the 8800GT. I tried switching the cards around and my PC would then post on the 5770 and not the 8800GT. So it's only allowing output on the 2nd PCI E socket (the one running x8 not x16).

Is this normal? Is there something obvious i'm missing?

Windows now also says I only have 3580mb of ram... While in the bios it said the full 4098. AWESOME!

I'm just stumped as to why the first PCIE socket doesn't post.

I have no idea why it is doing that.

Nvidia drivers disable physX if they detect an ATI card in the system anyway though.

Ram wise, are you running a 64bit OS or 32?

I was planning to use the phsyx mod. Had already downloaded it to my desktop ready to go.

I am running 64bit win7. The ram issue is strange. Its kind of like I took the 8800GT out and windows thought that 512mb was its ram and now doesn't read some? Idk lol.

In all my cleverness I thought I would reset my own cmos, mainly because I've never done it and it doesn't hurt anything right? NO! I failed to realised it would wipe my raid drivers now my PC wont boot rofl. Ah well, I'll just have to install win 7 on another HDD and run the drivers that way.

Stupid computer, stupid me.

Ok, I have figured out why my PCIE 2 slot would dominate. I had a bios setting called 'Dominant PCI Slot' (something meaning that anyway) and it has settings PCI, PEG and PEG2. It was set to PEG2 which I assume was the 2nd PCIE slot. I set it to PEG and win!

After I booted to windows with the 8800GT in again I now only have 3320mb of ram. It's slowly dwindling away! I'm going to run the windows repair tool off the cd and see if I can't fix it.

Anyone have any other ideas?

I have no onboard video at all. This only occured after the 8800GT evil card was installed. Must've put a curse on my system

Try booting with stock clocks to check that the overclock isn't the problem, I had a similar problem due to a slightly unstable overclock and RAM disappeared.

I figured out the problem was due to hardware reserved ram. It must've had something to do w/ the 8800GT but I can't figure out what. Its all good now, theres only 10MB still H/W reserved after I switched a bios setting and unchecked the mem box in msconfig > boot
