Anyhow, the card is supposed to throttle itself back and forth between 2d(275MHz) and 3d (430MHz or 450MHz with new bios), and it was not doing that, so I sent it back.

I set it higher in RivaTuner and got all sorts of graphical glitches, just like you said.

Even when set higher it only got 20fps or so, still nothing near the right amount.

Looks like you are plagued with the same problem. I would RMA it.

Interesting - it appears to have nothing to do with the video card.

I took it to some friends who work at PC Club and we changed some parts out to try to isolate the problem. We dropped in a 3200+ chip in the exact same setup and it runs beautifully. After some further digging, it looks like the motherboard BIOS flash allowed the MB to recognize the dual-core chip, but not to fully support it.

So, I have the choice of changing to another motherboard that might be more compatible with the 4400+, or just leaving this 3200+ in place for a bit until another BIOS update comes out.....

3DMark05 now 7860, from 5200

so Yorick you're saying with the 3200+ chip you're 7800GTX runs at the speed and performance that is expected? I have a gigabyte ultra9 running the F4 bios, there is also a F5bios out but I have not yet tried it. Probably try it when I get home, I was about to send the vid card back to EVGA

Interesting find there.

I know my problem was not the motherboard, becasue bios 1005 for A8N-E fully supports dual core cpus. Hope you get that sorted out!

<--Waiting for the RMAed video card.

Everything has improved - even with the slower speed of the 3200+ chip. Gameplay in BF2 was fluid with all settings on high and 4X AA, and not ONE "the connection to the server has been lost".

One thing that was pointed out to me on testing was that my problems with the 4400+ chip were not just in BF2 - the mouse would stutter and jump in Windows, and cpu load was sitting at about 40% with no apps running. I was so focused on BF2 I missed the other stuff.

My friends at PCClub have seen this occur with nearly every NF4 939 board they sell - some basic incompatibility with dual-cores. Hopefully a better BIOS is forthcoming, because I would really like to see this 7800 stretch its legs.
