Ram in Sync over extra MHZ

So... Is it better to have ram running 1:1 then to get an extra 200mhz?

Abit IS7-E
Geil Golden Dragon PC3500 running 2-6-2-2 at 400mhz right now.
P4 2.6C running at stock
Stock intel HS/Fan

Since the RAM is only rated for PC3500 I could assumably OC to 216fsb and run it at 1:1 no problem. But to go above that I would need to change the ratio to like 5:4 or something similar. Is it more important to have the ram run in Sync or to get a more Mhz?

The system overall will work more efficiently at the 1:1 ratio. Your system clock really is the MAJOR factor of how fast the comp will run. Have you tried upping the system clock to 215? It will give you a 2.8ghz system but those timmings will have to go back to stock which is nothing to cry about. I got My barton 2500 doing 220 clock with the Geil Golden Dragon kit with timmings as listed below.

Segata 80gb SATA 8.5ms seek

Do benchmarking both ways. Then see which is faster.
Then tell us the results.

My understanding is that for AMD systems it is very important to run cpu/ram in sync. However, you appear to have a Intel system. From what I read, running out of sync is not a problem with Intel systems. Hence, go with the higher FSB and run the 5:4 divider.

Benching it both ways for yourself is good suggestion too

Yeah since you have an intel system bandwidth is more important than latency. Keep it on 1:1, up the timings as far as they will go (3-4-4-8 should do) and then see how far you can push it. When you start getting mem errors try upping the mem voltage a bit.
