After much searching online for a Video RAM test, I found Burn-In Test Pro. So far, I like it. Following is my system.
Asus A7N8X Deluxe 1.04 1004 final
Athlon XP 2400+ multiplier at 12
2 512 XMS 3500C2 at 6-3-3-2 166 mhz
Gainward GeForce4 Ti 4200
Windows XP Professional SP1
Problem: Video errors that persist through reboot during POST. Error occurs primarily during heavy game play (Flight Simulator 2002). Garbled display can be cleared only with complete power-off cycle. Microsoft OCA reports both driver and device failures.
I have tried different drivers. I get the same results whether using 30.82 or the latest Detonators. Also, the video display problem existed when I was running the XP 2400+ at default multiplier and FSB.
My system passes the BurnInTest 2D and 3D Video tests. However, total Video RAM does not agree with the card specs. Burn-In-Test shows 61.30 MB RAM total and 60.75 tested. To me, this sounds like I've a bad video RAM chip.
Is it accurate to state that BurnInTest goes beyond sys info and actually searches the video card for operational video RAM and displays it as total available? If so, this makes it an invaluable diagnostic tool for video cards as well as its other functions. The few other inexpensive dianostic tools I've seen appear to simply repeat what Windows shows in Device Manager.
Is there any reason for me to look elsewhere for the source of the problem?
