GTX260 Problems after upgrade.

[ftwd]

Hi all,

I recently upgraded my machine to

AMD Phenom II 9950 Quad
M2N68-VM mobo
MSI N260GTX oc
4 gig ram
Xigmatek NRP-MC651 psu
on WIN XP sp3 home edition 32 bit.

Since upgrading the CPU, mobo, ram and graphics card I have started to get strange anomolies in FS9. About 10 min into a flight out of Brisbane Australia when the graphics start to get more complicated, the image pauses for just over 10 seconds then I start to get ground textures in the sky, aircraft textures on ground tiles and if I change from the 3d cockpit to the 2d one, I get a screen just full of autogen textures! I have checked the GPU temps and they have never exceded 61 degrees C when the problem occurs. My PSU is designed for nVidia SLI and I am running off two different +12v rails each with 18amps. I have the latest nVidia drivers installed and I used driver sweeper in safe mode before installing them to get rid of the previous driver.

I have tried tried reducing the USERVA to as low as 2304, but I still seem to be getting problems.

In FSX, I completed a flight from YBBN to YSSY then after landing I had verticle spikes comming out of the Autogen. When I changed views, the whole thing locked up and I had to turn the PC off to get out of it.

Is my GPU stuffed???

Cheers,

Nathan

Ok, from what you say, i guess there is some kind of conflict there.
Its not a super machine, but its a "so so" machine.
4gb of memory, are they separated? If yes try to take one out. See if it works better.
Im not a Guru but i guess there is something there not working right.
850w seem more than enough to run that sys.
But i guess there is something there saying "NO".
keep us posted.We all know that fs9 doesnt take "advantege of multi core" but....
thats an ok system, so that must be something saying "no" to FS9

The BUFFERPOOLS setting is a shot in the dark, really. It either works or it doesn't, there's not inbetween. Moreover, you have to have the right number for it to work right. I used to have that setting in .cfg, and it was at 250million working fine, but I've taken it out altogether now as I only tweak by the autogen sliders in the in-game settings. Quite honestly, it's best to leave the fsx.cfg alone. The only thing you should really change is the widescreen setting to TRUE if you have a widescreen monitor, and the TEXTURE_BANDWIDTH_MULT to 70 or 80 for your system.

I know what it's like to have to return hardware and wait the long wait... Best of luck with your new card!
