Iam going to order some Mushkin PC3200 Level 2 and Iam wondering how much of a difference would it be to 1g (512x2) verses 512MB (256x2). Iam now running 512Mb (256x2) of Kingston hyperX and this stuff is crap. at 200mhz i have to run timings of 2-3-3-6 for it to be stable with no errors. the best timings i have gotten was 2-2-3-5 but it will only boot every 3 or 4 times and Memtest86 shows errors Big time. Thanks
