Thread: What's my bottleneck?

    Hoping you wizards can help me out here. My computer can only make 3268 3DMarks on 3D2003, on a good day. Of course that's an improvement on the 78 it got before I replaced the video card:

    Intel D845GEBV2 motherboard
    512MB Crucial PC2700 RAM
    Windows XP
    ATI Radeon 9600 Pro
    Soundblaster 5.1
    Intel Pentium 4 2.4GHz

    I think my big problem is the motherboard, but I'm pretty ignorant about these things. Am I right that this MB only supporting up to 4X AGP, and the speed of the bus and/or RAM is slowing things down?

    Suggestions, please?

    That score looks right to me. I use a 128mb aperture size in BIOS and get better results than the default 64mb.

    3DMark03 is about 95% video card, 5% CPU/MB/RAM from my experiences.

    That score is about right. If you overclocked it you would see some good gains.

    I know how to change the aperture in the BIOS, I will try that. My one adventure in trying to change the BIOS timings to something other than AUTO resulted in failure to boot, so I had to clear the BIOS and start over. :(

    Aperture is wicked easy, its even on my dell :eek: . All you do is find something that says "Aperture size" or something like that, and change it. For example, mine changes in between 32MB, 64MB, 128MB, 256MB. Since I havee 768MB of RAM, I leave it at 256MB. You should leave it at 128 or 256, whichever gives you better performance, try it out. Also, if you want a higher score, disable all back ground programs that arent system, get rid of your desktop, and shut down all power management options and your screen saver. It's kind of bending the rules, but if does help. Anyways, good luck :thumb:, : peace2: Mista K6

    OK, I changed the AGP aperture size in the BIOS from 64meg to 128meg and the 3DMark03 score improved to 3322. Not much, but any little bit helps.

    One game I am trying to increase performance on is Microsoft's Combat Flight Simulator 3. Their website has a list of things to try: one of them was to make a permanent swap file. I tried that and still have a problem in the game of it "stopping" for a second while the HDD does it's thing. Is my computer only capable of doing one thing at a time?

    I'm already running no screensaver, anti-virus, or powermanagement. How do I get rid of the desktop and disable all of the background programs that aren't "System", run msconfig? How do I know which ones I can safely stop?

    Got rid of the desktop; disabled everything that wasn't Microsoft; still not much improvement on 3DMark03: 3368. Finally got 3DMark2001 with patch to run: 10822.

    If I get brave I will try overclocking the video card.

    Yeah your 3DMark01 score is right on as well. I could probably get that rig doing 13k.

    Hey mate, I was just reading through old forums and what not, and read this one again, forgot to mention something the first time. Have your tried tweaking your system yet? The Windows Xp tweak guide (called "Windows XP: from reformat to relax") is very good, and go to the site www.pureperformance.com . If you apply most of the tweaks from these two sources (the ones that pertain to your system and arent too risky), you should see a big improvement in scores. Just a thought :thumb: , : peace2: Mista K6
