9500 Pro Resolution Prob UT2003

[KROME]

im experiencing problems running UT2003 at 1280x1024 when set at this resolution after a few minutes of gameplay system will spontaneously reboot no error no lockups just reboots. im currently running Cat 3.1 drivers, XP pro, DX9 all XP and UT updates also currently set open GL and Direct3D to best performance (note: i have used Cat 3.2 with same results and also reinstalled UT2003)

what i have done:
disabled fast writes in bios, bumped AGP voltage +2 also i am currently using rivatuner to start system with 4x AGP set at startup (system would reboot if it was set at 8x no matter what setting) im just kinda stummped at this point as to what i could try next im thinking its possibly the board and the VIA chipset ive read tons of forums stating there was an incompatiblity with the KT400 chipset. but i have no idea any help or tips would be appreciated

System:
XP Pro (All updates fresh install)
gigabyte GA-7VAXP (latest bios)
1900XP ( not overclocked)
Volcano 10+
512 DDR 400 KingMax (default settings in bios)
RaidMax 500W PS
2 Seagate 80 Gigs 7200 RPM
1 Maxtor 40 Gig 7200 RPM
Winfast XP Deluxe TV Tuner
DVD and CDRW

Your running the ram at 266 or 333?

im running it at 400Mhz the defaults settings

Does it lock up at any other resolution? Also unless you have an LCD you shouldn't be using 1280 x 1024 anyway (although it most certainly shouldn't crash).

Try clocking the ram down. Could be your memory causing the crashes. I had a computer that constantly crashed when I tried to play a game. Back in the PC133 days ran it
at PC100 and the crashes stopped.

i do have an LCD 18" Dell deal but i just cant figure out why in the world it would just reboot like that ill do as suggested and try running ram at 333

and it doesnt lockup at any other settings except higher than 1024x768

also i havent tried any other games yet to see if it causes the same problem i just got Splinter cell and Unreal II ill give those a try and see what happens

The video card would use more memory at higher resolutions.

Try to check what your fsb speed is in windows. You can use wcpuid to check or cpu-z.

its says its running at 133.96

happy to say all seems to be running well since lowering my memory to 333

actually just did Benchmark and got better scores than before

Before
