ok i upgraded my axp to an opteron 146, so im using 1x512 and 2x256, which means single channel in this asrock board. i vmoded to get 3.1v and can get it into windows fine at 233-240, but it fails p95 after 2hrs. ive heard its not wise to run 3.3v with an a64, so i didnt do the 3.3v mod. so what can i do to get this bh5 running at a reasonable speed? find another stick of 512 and stay at ~200 2-2-2-5 ? risk the 3.3 vmod ? run 2.5-3-3-6 (would be really slow since itd be single channel and slack timings?) ?
