A8R32-MVP w/4GB

Riptide · 02-16-2008, 04:42 PM

I'm having a problem with this motherboard. 4x1GB, pc3200 OCZ3200EL

If both matched pairs are installed the system will no longer properly recognize the 7950GX2 video card. In fact, Vista Ultimate completely loses the Display Adapter subsection in device manager. You still get a picture on the screen ofcourse, but it's using the default standard VGA driver.

Nvidia driver refuses to load entirely.

If we remove one set of matched DIMMs (so it's back to 2x1) then it starts to work. The board does not seem to like all 4 DIMM slots filled.

We have the memory hole enabled in the BIOS but turning it off doesn't help - it just keeps Vista from seeing all 4GB.

I would check to see if the memory timing is at default and check the voltage for the memory.

vDIMM is set to 2.7v. Command rate 2T. Clock 200Mhz. And timings are set properly.

Hardware memory hole is enabled. 4GB shows up in Vista under properties for the system. But it refuses to see the video cards properly. He takes 2GB out and it works again.

There is a PCI-PCI bridge showing up device manager with an exclamation point. Removing it doesn't help. Comes back in a problem state again and complains about insufficient address space for it to load.

Check to see if there is a bios update you can get.
