Conflict between graphic card Gigabyte 630 GT and 2 memory modules

[sulsoft]

I have a weird conflict in my PC. When i start Windows 7 with Gigabyte graphic card 630 GT 1 GB PCI-e installed and 2 memory RAM modules 2 GB each, my graphic card is not recognized by Windows, i see an exclamation in PCI Express in Windows Device Drivers.

 

I had tried with memory in Dual Channel and without, and the problem continue. When i remove one RAM module and run computer only with 2 GB, my graphic graphic card is recognized and problem dissapear.

 

I never saw this kind of error and i need your help please.

 

Computer specs:

 

CPU Core 2 Duo 3.0

 

Motherboard AsRock conree1333-esata2

 

2xDDR2 667 Mhz 2 GB each

 

Graphic Card Gigabyte GT630 1GB DDR3 PCI-express

Is this 32 bit Windows?

[sulsoft]

No, Windows is 64 bits

Have you run memtest to verify both ram sticks are up to par ?

Run memtest on both the modules to be sure that both of them are good.

I've tried memtest from Windows7 but i don't see any problems with RAM. This can be for some reason a conflit with NVidia cards? I ask this, because in the past i have put a ATI video card from a friend, probably last year, and the problem solved for himself.

Did you have and anti card in this particular rig prior to the nvidia card? And you're 100% certain that this is a 64-bit install because the problem seems very indicative of a common issue with a 32-bit system.

Or a BIOS setting...

I'm sure that Windows is 64 bits, not 32 bits. About slots the motherboard have 1-PCI-E x 16, 1-PCI-E x 1, 1-AGI x 4 (is used to install PCI-E expansion cards, i think like in crossfire), and 3 PCI slots. Now, the NVidia 630GT is in PCI-E x 16 slot.

 

What is strange, is when i remove one RAM dimm module, the video card is detected, and i can install the video driver software, but i note strange symptoms. I explain. One is when Windows start and it shows "Windows is starting", i don't see the colors like a flower, i only see a dot color point. In the other side, windows start the reveal some instability, and randomly windows hangs in black screen saying "Windows is starting", and the "flower color" as i say, don't appear.

 

 

 

In BIOS i've looked up, and the only option i have is in tab "Chipset configuration" the entry "Primary Graphics Adapter" - Choice between "PCI" and "PCI Express". I don't see other video option.

 

Strange problem, or better saying, strange WINDOWS/MICROSOFT problem.

 

Any ideas is appreciated ...

Is this a fresh install of Windows 7 64-bit or an old install of Windows 7?

 

Check to make sure that you are running the latest BIOS released for your motherboard - THIS IS CRITICAL.

 

If you aren't running the latest BIOS, flash to the latest BIOS.

 

If you are running the latest motherboard BIOS;

 

1. Power down machine  

2. Unplug power supply from socket

3. Move CMOS jumper to clear position

4. Remove motherboard battery

5. Install video card and two memory modules

6. Move CMOS jumper back to save position

7. Install motherboard battery

8. Boot into BIOS and load optimized defaults, save and exit

 

If none of the above suggestions work, then you have to consider that this might be a hardware problem or a Windows problem.  Before I replaced hardware I'd do a fresh install of Windows.

 

My best guess is that you aren't running the latest BIOS release for your motherboard and that is causing compatibility issues.
