Help...UT crashes

[legacy-spoC]

I just added another 512 mb of memory to my system. Makes the total 1 gig. I have a dual channel mb (gigabyte GA-7N400 Pro2). Everything seems to run fine, but now UT2k4 crashes when I get into a game (any mod). I get this error:

UT2004 Build UT2004_Build_[2004-11-11_10.48]

OS: Windows XP 5.1 (Build: 2600)
CPU: AuthenticAMD PentiumPro-class processor @ 1733 MHz with 1023MB RAM
Video: WinFast A250 Ultra (5306)

General protection fault!

This rest of my system:

Athlon xp 2100
Leadtek GeForce 4 4600 ti
Memory is samsung pc2700 (both sticks purchased at the same time)

Thanks in advance.

Both sticks? so you now got 3?

Try all of your sticks one at once .... you might have got a bad one.

3 sticks???

:confused:

My comp only holds 2

I only have two sticks. Both are 512. I switched them and the new one is bad. I also tested it with Prime95. It failed after 3 minutes.

Thanks for the advice.
