3500 @ 2.75 rock solid but wont go higher?

Hrmm well ive found that lovely happy medium where your rig loads at 38c and idles at 33c at 1.45v. 24hr+ rock solid on sp2004 and prime95. I should be happy but you know we gotta try to push it a bit harder. Anything beyond 250 fsb just wont be stable. I have the ht at x3 mem at 2-3-2-6, recommended for corsair XMS, and the mem voltage at 2.9. I ran just a cpu stress test in sp2004 and she wont be stable for more than 10 min even at 1.55 volts. My temps don't rise much but stepping it up 4 times and no stability stress test wise seems odd. Any suggests on what could be holding it back or is it just at its max. Thanks much.

Have you tried running a memory divider, it could be your thats holding u back.

Still thats a very nice overclock.
