crucial said its their standard memory and not intended for performance and recommend running @ 1.35v but also said it should run fine on the biostar a880gz at 1.6 volts
but you having said that i'm not sure if it's worth a shot. should i take this chance?
If not, then there are a couple more alternatives I'm currently looking at in light of what xd said. They are both nearly identical G.Skill but with one being faster and the other being more stable due to the '2N' difference, albiet more expensive.

Your 1.6V limitation was common on some motherboards of the 700 series chipset gen - incl. Gigabyte midrange-high end 700 series boards.
You won't see a significant difference between running at 1066Mhz or 1333Mhz although timings may reasonably change the bandwidth end-result as found in benchmarking programs (i.e. you can expect similar performance between 1066 CL7 and 1333 CL9 but make that 1333 kit a CL7 and things change); note that AMD platforms can benefit from both frequency and timings unlike Intel platforms which generally only see gains from higher frequency. That said, if you want better RAM speed flexibility, you should not be investing in lower-speed generic memory ideally be investing in DDR3-1600 for a better guarantee on ICs binned for high clock speed operation. Generic DDR3-1066 CL7 and 1333 CL9 kits are among the lowest speed/timings standard you can find for DDR3 kits today and being a minimum standard you can run most ICs with these settings - including those that aren't designed to run past a certain speed operation, which can impact RAM ability to OC and in some cases system ability to OC by limiting ref clock OC. By default modern DDR3 RAM already provides enough bandwidth for most system tasks and regular-use non-intensive apps, although an increase in bandwidth and lowered latency through RAM tweaking can uphold a general sense of higher "snappiness" to the system by making faster the memory that super-fetched programs and data are stored in - as some folks have reported.
if i would be trying to squeeze the 'last bit of performance' out of my system w/o hardcore overclocking i'm guessing mid-end ram would be nice.
what ram spec & budget am i looking at for a product that fits this description yet gives flexibility for light overclocking?
a DDR3-1600 CL9? and should the voltage be => 16v or < 1.6v w/ heat spreader?Edited by Stealth3si - 2/4/12 at 12:10pm
