preliminary, testing (just booting up into bios) is much more impressive than i expected. a fsb of 290( thats as hi as i can go) at 5/4 (232) with 2-2-2-5 timings i can boot up into bios easily at a 2.88 voltage. unfortunately, my ic7 wont allow me to change the default spd(2.5-3-3-7) timings running a 1-1- ratio. but even with these settings i was able to boot up to 240(ddr480) at 2.88v. at 3.08 volts i can boot to 250(ddr500). I suspect 260 or more(ddr520) with 3+ volts is obtainable at loose timings with a board that isnt as finicky as mine...
All and all this is some real nice 5/4 memory for 49 bux. when i get finished testing, ill offer it to someone for what i paid for it...
