What would give the best performance? RAM running at 150MHz with slow timings or ram running 125MHz with fast timings?

But a better comparison would be 150mhz with low timings vs. 140mhz with aggresive timings. With that comparison the 140 with aggresive timings would give the 150 a run for its money. There the faster timings would close the gap.

The best way to find out is to benchmark at each setting.. I myself have found out that running at 200fsb with timings 5,3,2,2 gives me about 300 more points in 3dmark03 than running at 210fsb 6,3,3,2.5.... Even though the fsb is higher at 210 it is taking extra clock cycles for each command. It's just like running a higher fsb is almost always better than rasing your multiplier.. Like running a cpu at 10x200=2000mhz is better than running that same chip at 12.5x166=2075mhz...

But if you can run it at 210 6-3-3-2, I think it will beat 200 at 5-3-2-2 or even 6-2-2-2. There is about a 10 MHz (rule of thumb) difference between cas 2 and cas 2.5 for 3D. I always keep things at cas 2.
Many memory spec at cas 2.5 can make it to cas 2.
