i have no idea as to what it means to tighten timings.... what are the default settings for buffalo pc3700 and what would tight timings?

what does "tight timings" mean?

Technically, tight timings are waveforms that have very little margin between where a clock edge occurs and where you can read or write data.
Of course when people around here talk about tight timings, that's not what they mean. When some one says they've tightened their RAM timings, they usually mean they lowered their CAS latency and associated delays. The "tightest" timings are usually 2-2-2. "Looser" timings could be 3-3-3, but there can be values in between.
I haven't seen published timings for Buffalo PC3700 other than "CAS3". That probably means the SPD-programmed timings are 3-3-3 or 3-4-4.

so with high fsb, would tighter or looser timings be good?
how about in general?

CAS Latency(Column Address Strobe)
RAS Latency(Row ......)
RAS Precharge (No idea)
Bank Cycle tme(no idea)
Basically, the lower numbers, the faster.
Most people will tell you
2-2-2-6 are the fastest you can go, but for serious over clocks the middle two numbers are higher by .5

hmmm how do you consider those?

Didn't change anything yet.

With those chips (BH-5) you should be capable of setting the memory timing (in your bios) with a CAS Latency (tCL) of 2.0, a CAS-to-RAS Delay (tRCD) of 2, a RAS Precharge (tRP) of 2, and a RAS-Pulse Width (tRAS) of either 6 or 5.
Unless the PCB (the board on which the memory chips are implanted) on your modules is lacking, you should be capable of setting these timings and raising the FSB to around 210-230MHz (somewhere in between; results will vary) at 1:1.
VDIMM (voltage to your memory) can be raised to your maximum allowed by your bios, which as long as it's below 3.0 Volts shouldn't have any impact on your memory. Be sure not to over-volt - meaning if your memory will run stable at it's highest overclock at a lower voltage (meaning if your running stock or a purposely low FSB, don't be running at a higher voltage then required to run stably).
