    In order to feed your obsession with the FD benchmark ;), I just did it again after disabling those monitors my results went from...

    Random Pixels 700 KPixels/s
    Lines 438,333 Lines/s
    Circles 9,244 Circles/s
    Rectangles 21,035 Rectangles/s
    Texts 309,553 Chars/s
    FloodFills 3,775,840 KPixels/s
    Draw 34,678 KPixels/s

    ...to...

    Shaft,

    Hmmm. That is some big changes. I'm seeing rectangles @ 4x but lines dropping 2/3's. Floodfills are way up too. Can you plz run FD twice in a row? Sometimes I have noticed my card 'starts' @ 366pixels on the 1st run, but the 2 time thru it goes to 433.

    If we can get the Random & the Lines back to where they were ... ;)

    Try a game, run FD twice, make sure hardware acceleration is still at full, run Cacheman & please have some more good news. :cool:

    What are your thoughts from what you are actually seeing? What has made the biggest difference?

    HTH & thanks for the info, :D

    I did run it twice in a row with the same results. The biggest difference was in RTCW where I gained up to 20 fps on one of the open area maps. Max Payne gained a little less than 5 fps.

    Shaft,

    Well now! 20fps isn't anything to sneeze at, even 5 on Payne is better. :D

    I'm glad you're seeing improvements, now if we can get the 'Random' up I think the lines will follow. Are you up to a *little* oc 'test' to see if the #'s change? I'd like you to DL 'Riva Tuner' from www.guru3d.com & 'see' what the card is presently clocked at. No ocing 'til we find that out. ;)

    I realize you have a new card & don't want to oc it, but if we do a *slight* increase & the #'s jump ... :cool:

    Slow but sure, we're getting there. :D

    It's already overclocked to 300/650 from 275/550, so I don't want to o/c it any more.

    Shaft,

    Hmmm. That's a 9% oc on the core, which I agree is safe & should give some improvement. :D

    I do think the 550 to 650 (18%) is a tad on the high side tho'. Try bringing it down & run FD between the settings 'til the 'random' starts to improve. I *think* if you slowly 'tweak' w/Riva your #'s will get better. I know mine have. :cool:

    Enjoy,

    My vid card is the coolest running 4400.

    The ram o/c is perfectly safe. The ram used on the card is some of the coolest around, and many websites have done extensive benchmarking with it at 680. I tried using the default settings, but the FD benches didn't go up (they actually went down, not suprisingly), so I returned them to the oc'd settings.

    I'm either going to try upgrading my PSU to a 400 Watt ATX using an adapter so it'll work on my Dell mobo, or the 1.4ghz Tualatin Celeron using a Powerleap adapter...or both. I'll get to the bottom of this sooner or later!

    The new 1.4ghz Tualatin Celeron is now in and my problem has been significantly reduced. I no longer drop below 30fps, so my games are almost always smooth. There seems to be some bottlenecking left from my aging chipset, but nothing drastic. The upgrade has definitely extended my computer's lifespan until I get the money to get a good AMD system (maybe next year).

    I have the same problem, I upgraded to a PNY Geforce 4 TI 4400 from a geforce 2 gts and the performance stayed the same. Lots of people are having this problem(CHECK THE LINK BELOW). I upgraded to a 350W PSU from a 200W Dell PSU, I also upgraded my MOBO.

    I hope someone here can help!!!!

    Here are my specs.

    I bought the system from Dell.

    PIII 1000 Mhz
    Intel D815EEA------> Upgraded to an Abit ST6
    512 MB PC133
    40 GB Western Digital HD
    PNY Verto Geforce 4 TI4400
    Sound Blaster Audigy Platinum
    3COM 3C905C-TX
    Mitshubishi Diamond Plus 72 17' Monitor
    Samsung DVD-ROM SD-612
    SONY CD-RW CRX140E
    200W Dell PSU------> Upgraded to a 350W PSU
    Windows XP Home Edition

    Hey, thanks for that link. You might want to try the same upgrade I did. Does your mobo hold a Slot 1 processor? If it does go to www.Powerleap.com and look up the PL-iP3/T upgrade. The PSU upgrade didn't help any?

    Nope, my cpus a socket 370, I have just about given up, noone seems to know what the problem is. As for the PSU it didn't help at all. I had to buy a new MOBO because dell and other PC makers use proprietary connections for their MOBOs, cases, and PSUs. I couldn't use a standard PSU on the Dell made MOBO.

    That's not entirely true. You could have gotten an adapter to use a standard PSU in the Dell for about $10 from Centrix-intl.com, which would have saved you quite a bit. As for the socket 370, that's much better for you since you could go straight to a Tualatin chip (if your bus is 133 you can get a 1.4ghz Tualatin PIII I believe).

    It would be cheaper just to buy the 1.4GHz Pentium III Tualatin. Costs more for the powerleap.
     
  15. Shaft

    Shaft TS Rookie Topic Starter Posts: 100

    That's what I meant. You don't need the Powerleap adapter if you're mobo is a socket 370 instead of a slot 1.

    I might try that. How much of an improvement did you see when you upgraded? Does the fps stay above 40 even when a lot of action was on the screen?
     
  17. Shaft

    Shaft TS Rookie Topic Starter Posts: 100

    Almost always. It very rarely dips to even 35 fps (anything above 30 is perfectly smooth), so it's a very worthwhile upgrade, IMO.

    Boo,

    WOW! I got thru about 1/2 the thread @ MO. :confused:

    For your problem, have you got this: http://fae.abit.com.tw/eng/download/bios/st6.htm , it's the latest BIOS for your board.

    Since you also have the i815 chip in that Abit board: go to Intel & get the "Chipset Installitaion Utility" & the "Application Accelerator". Both will speed up the transfer of data from the HD to the CPU.

    Someone said that the AGP runs thru the PCI: it does NOT! AGP is a dedicated port with direct chipset, memory & CPU access. :cool:

    Install those, if ya would, & let me know if that makes ANY improvement. Do you also have DX8.1 & is 'Pure Hardware T & L' available for you?

    Got a MO 'compare' link? ;)

    HTH,

    Already hav the application accelerator installed as well as the chipset software, also have the latest bios installed. Pure Hardware T&L is available, and heres my compare link.

    http://service.madonion.com/compare?2k1=3923638


    and here are my FD results,

    Boo,

    Your MO compare doesn't show me much (dang it) & getting that score higher only requires degrading the video quality. That's what all that LOD bias, AA, anisio, W-buffer, etc. disabling does.

    FD shows me a lot! Your random pixels & lines are low! My MX400 triples your line count & my RP's run 433-466. All the rest you smoke me on tho'. I'm running the i810e chipset, Celery 500 & a PCI card.

    Do you have Riva Tuner? Increasing the 'core clock' will raise the RP's & lines. Too high & they go back down tho'. :rolleyes:

    Have you run the FD HD benchmark or the Multimedia bm? This is an odd problem & so widespread too. There has to be a common element & I'll do my best to help ya find it. :cool:

    Hmmm,

    I dont use the LOD bias in MO, AA is off as is AF, everything is set to normal. I use rivatuner all the time, I'll OC my card and do another test.

    Boo,

    Have you installed the 'Patch scripts' in Riva? The 'Matched Detonator Database'? They are in 'Power User' & you have to install the ' Matched Det Database' 1st.

    What are you clocked @ now?

    Quick thought: shutdown your Anti-Virus program & run a benchmark. If you have McAfee .... it has been known to cause problems like this.

    Well, OC my card didnt bring up my scores much.

    Ok, I installed them i think, and Im not running an Antivirus prgram in the background.

    Ok, I ran the bench again and got a little bit better results,
