Why do I get lower 3dMark Score when I break 800 on PIII

[bhungy]

I have p3v4x and when i overclock my PIII at 800 it gets a score of 5200 with a geforece ddr. But when i overclock it some more the scores start to decrease! WTF is going on. Shouldnt the score increase as I increase the speed of the cpu?

That's interesting, I have been wondering about my 5000 score on 3Dmark2000 on my P3 700e @ 933.
I have a 64meg GF2 GTS card and it should be hitting 6500 - 7000.
I will try different speeds and see what happens, see if you are on to something - I had this set up with a different P3 700e CPU running at 868mhz and was getting 6700 3Dmarks.

Are you running the benchs off the CPU? or onboard vid T&L, perhaps one or the other is bottlenecking and possibly decreasing performance,... blind guess here...

 

[bhungy]

Another funny thing is when I try to change the speed of the ram to case 2 it becomes slower on my 3dmark also. For some odd reason my computer likes it on case 3. If i bump it up to case 2 the scores goes down. WTF?

Supradude: Huh? I am just starting 3Dmark2000 and running the benchmark default.

 

[Wiz]

Wow bhungy, what mobo are you using and what brand / speed ram?

The more programs you load on your computer the lower the score, too. When I first got my machine I got 8444, but now I get in the middle 7500. If I overclock video card, then I can get back to 8000.

cmamath you overclock that system of yours yet????????? crank that badboy up.

 

[cmaMath13]

I am getting VERY tempted now. I think I am going to start with my video card.

same thing happened to me.
with my cbo 700@900 i was getting near 6000 in 3dmark and was maxing out the memory benchmark on sandra.now with my cco 700@1050 my 3dmark's are low 4000's and my memory benchmarks in sandra are way lower.

Yes, it makes me realize why guys that buy from Dell or other PC companies get such low performance. It is because of all the crap they load onto the hard drive!

I am still getting very good performance, but I think I will reformat more frequently now. Plus, it is very easy to do now that I have a restore disk and a CD-RW.

I've seen similar performance hits when running at around 1 GHZ or higher with my PIII-800. Generally I've attributed it to errors in the cache which slowed things down while the error-correction did its thing. At 935 everything is fast and no unexpected slow-downs.

hmmm... I changed the memory timing from 5t/7t to 7t/9t and installed DX8 final.
My 3Dmark2000 score went from 4997 to 6651
Changing the timing was related to a stability issue. DX8 final seems to have done the trick under Win2K server. About the same score using both Det 6.49 and 6.67 BTW.

Any suggestions what I should do?
My mobo is an asus p3v4x with PIII 600 overclocked to 800 and my ram is 256 pc133 infeneon ram, i think it is cas 2. Anyone have any suggestion for the timing of the ram?

 

[cmaMath13]

I think I saw somewhere that running you memory at cas 3 will increase you 3DMark2000 score (instead of cas2).

Don't worry too much about your score. If it runs the games you play than that is fine. I don't think your score is that bad anyway.

i get 8700 on 3dmark

I never use 3DMark as a benchmark. Too quirky. It does, however, make an excellent stress-tester for overclocked systems to test stability.

When in doubt, timedemo Quake 3. Unless you're testing Direct3D. Don't know of any games using it that benchmark well.
