More RAM Less DOOM

Recommended Posts

Hello Forum!


Admittedly, I am a newbie when it comes to over-clocking anything – so try not to use big words if you try to help me. I just tweak until all hours of the night sometimes. However, with my latest upgrade, I’m frustrated enough to ask for some help.


The Problem:

I upgraded my RAM from 1 to 2 gig’s and now my benchmarking scores have actually gone down!


I was getting over 13K with 3DMARK03, now I can squeeze out about 11K. My FPS with Doom3 when from 49.5/62.5 to 42.8/56.8 (and I have artifacting over 800x600).


I would appreciate any help or advice.

running 4 sticks of ram?


each additional ram stick will result in the MB running the ram slower. THats because its harder to get the signals to match.


You will always get a higher ram OC with one stick one chanell.


You could try boosting the RAM voltage and setting the RAM timings in the BIOS manually but that may not help.
