Timings vs. bus speed

[Fireball_dbz]

i'm running a neo 2 board with a new 3200 yay! when i reinstalled xp i noticed that running 200mhz with a timing of 2 2 2 5 runs fast than what i had before 280mhz with 2.5 3 3 7 so should i just run a divider and keep this settings on 200 +mhz on 2 2 2 5 or should i run it in a 1:1 on 250 mhz 2.5 3 3 6 what do you guys think?

What were you using as your benchmark to determine it was "faster"?

[Fireball_dbz]

boot time, window xp passes i get 1 pass for 2.6ghz 1:1 ratio half a pass for 2.6ghz with a divider 193mhz ram 2 2 2 5

boot time is not a good way to measure performance.

use real apps to measure performance, or benchmarks that simulate real world applications.

I know a lot of people don't dig it, but Sandra-lite 2005 wouldbe good to bench your system vs itself to determine what speed your system is really doing at both bus speeds.

how bout memtest?
but overall what do you guys suggest, tighter timings or higher fsb, i mean at 260mhz 2.5 3 3 5 is good right but i'm greedy, i want that 2 3 3 5 settings at this speed

[pershoot]

use everest, memtest and super pi 1m. my opinion, go for the lowest latency and tightest timings possible while going for the highest HTT u can muster at tight settings. once u find that, divide it up, and work towards getting close to maxing out the cpu (and or board) while keeping the ram closer to its limit.

u will feel the difference on A64 when the latency is low.

Latency is only one measurment of speed and by no means the most important. If I run my system at 9x278 with a 166 divider and timings of 2.5-3-7-3 my latency is lower than if I run it at 1:1 with timings of 3-4-8-4. However, my system is not quicker by virtue of the lower latency. Every other benchmark comes out better with the looser timings and the higher clocking of the ram. The rule of thumb as I understand it is that is 25mhz of ram speed will make up for the next level of looser timings. In my case the difference is about 50mhz, but the latency is still lower with the faster timings.
