My set up is: Gigabyte K8nS Pro, AMD 64 3000+ @ 2.4 GHz (240 x 10)
I had 512 Mb of old 333 Kingston Value RAM (Winbond chips) and I've exchanged that stick with a new 512 Mb 400 Kingston Value RAM. The new one is a 3-3-3-8 @ DDR400 based on Hynix D43, and the timings @333 are the same than those of the old stick.
In order to work with the O/C, the old memories were running limited at 166 MHz, that made them run at DDR400 MHz with the O/C, meanwhile the new memories are running at DDR480.
Result:
- The memory bandwidth measure with PC Wizard has decreased from 2.7 MB/s to 1.7 MB/s
- The FPS in Doom3 Demo1 test has decreased in about 10% in the second run, the first run remains about the same (only a bit worse)
- The Aquamark CPU test in the default mode has increased from 8900 to 9400.
Any help on knowing what happens with my setup? All the timigs are default. I can't understand why the memory bandwidth has decreased so dramatically, and it's obviously impacting FPS in Doom3.
Other things I tried:
- Without the O/C and the bandwidth was 1.4 MB/s
- Limiting the new stick to 166 MHz (I think forcing it to use the DDR333 SPD data) and the bandwidth was 1.7 MB/s, the AM3 CPU benchmark was 8900
I would appreciate any help to understand/improve this behaviour.
Thanks in advance.
