New system

[allmytopos]

Hi everyone,
I recently built this system for my personal use. The apps I run on it are games ( like doom3), map rendering software (ArcGIS) and office programs.

ASUS P4800-E Deluxe
P4 2.8 (prescott)
Cooler Master Jet 4
512 MB 3500 DDR
ASUS 9600XT
SB Live
420 watt Enermax PS

3DMark01 = 13200
doom3 timedemo (800x600, 2x AA, VS on, MED quality) = 31 fps

After a 48 hr burn in with 3Dmark I overclocked the system with the ASUS "Ai" by 5%. At this point I ran benchmarks and noticed a slight improvement in the scores. A few hundred extra points in 3dMark and a few fps in doom3. There was only a neglible increase in CPU temp (1-2 Celsius extra at full load).
So I pushed a little further to a 10% OC. (3.07 Ghz) The computer booted fine and everything seemed normal. However after going through the benchmarks I lost about a 1000 points in 3dMark and 5 fps in doom3 (down to 12,000 and 26 fps respectively). The temp from the CPU was 58C, a little warm but not at a level where the computer should suffer. I was wondering if anyone had suggestions for what might be causing the benchmarks to suffer at higher speeds. The RAM should be able to handle a minor 10% overclock right?

Thanks

You will find a point where increases in speed cause decreases in scores, this is normal. I would think it should be able to take some like a 10% OC, what program are you using?

It might be dropping your RAM speed by default when you set 10% over. I don't use AI overclocking, I use manual configuration.

You should be able to manually run at a 217FSB with PC3500 Ram. Remember though, you are overclocking the FSB making all these transactions faster, data moving faster, a game that uses more than 512mb of memory will suffer a bottleneck where? The ram! You should add another 512mb and watch your framerates then. Also, I'm assuming you're running 256 X 2. If you have a single 512mb stick you are running single channel instead of dual-channel. P4's don't like that.
