3dmark05 with 2.97 and 3.0 GHz

post #1 of 8
Thread Starter 
ok, ive been overclocking my pc over the past 2 months and have tested 3dmark05 with 2 different configs and scores:

Config 1:
CPU: 148 @ 3.0
Memory: ~200MHz
Video: 7800GT @ 490/1200
Score: ~8100

Config 2:
CPU: 148 @ 2.97
Memory: 270 MHz
Video: 7800 GT @ 490/1200
Score: ~7800

would 30 MHz of CPU speed make that much of a difference???? my mem is running 70MHz faster. it doesnt make any sense. any suggestions?

Why is there such a HUGE margin in the RAM, I wouldnt think there would be unless you're running a huge divider to get down to 200MHz.

Are the timings different?

well, its wierd because for 3G i have to run ridiculous voltages (1.648v) and divider on my memory to run. its not 100% stable yet, but i ran 3dmark to benchmark.

at 2.97 im able to run 1:1 with my mem (270x11) @ 1.584v stable as a rock.

i figured 30MHz less on my cpu and an additional 70MHz on my mem would kind of even out, but i guess not...

i think its 3dmark. i can one the test once and get 10,000 run right after that and get 9900.

Did you only test once at each setting? If so, maybe you should run 3 runs for a more accurate avg. at each speed to get a more accurate mean.

Some memory performs better at lower MHz. For example my memory can run up to 255MHz, but my benchmarking scores are far superior around 240MHz. That is my sweet spot so to speak. You might find yours is below that 270MHz mark.

Make multiple benchmark runs in 3dmark, and also use another benchie such as aquamark,running it multiple times for each setup as well... i would think that 30mhz less on cpu and 70mhz more on memory would be much better.

Yup, I think that's it. I ran 3DMark03 for the first time with the Sempron in my system, I got ~8400. Next time I ran it, with the exact same settings, I got 7890.
