e6750 oc issues

About 2 weeks ago I was able to run orthos blend test stable for over 12 hours with the oc in my sig rig. I had gotten new memory, g.skill PI's, and my oc went amuck. I'm back using my HZ's but have some issues. I started from scratch with my current oc. Set fsb to 450 with nb at 1.26 volts, sb at 1.2. Set cpu multi to 6 (2.7GHz at 1.35 volts). Mem was at ddr2 900 with timings to ensure fsb stability. Ran orthos blend for just over 18 hours.

Next I played with mem timings and stable at ddr2 1080 at at 2.34 volts (orthos large in place fft about 12 hours).

Finally put cpu multi back to 8 (3.6GHz at 1.43125 volts) and ran a blend test. Failed after 2 hours. Why would it be able to run stable blend test previously but not now under slightly changed settings? Running orthos small fft to test just cpu but still somewhat confused.....

Mine's a little iffy too, I'm trying to figure it out
Nothing over 3.2 works on my computer, and I think the E6750 is a locked Multiplier CPU, which is aggrevating.

So 400FSB (3.2ghz) it is.
Ahh well I see major improvements anyways so it's fine. Instead of 50% solid on sins of a solar empire I barely touch 15
On my ABIT IP35 pro I had my e6750 at 3.4GHz with no issues what so ever. Whats bugging me is that on my ASUS P5Q-E I had it stable at 3.6GHz. I decided to try new memory and ever since then it has been unstable. I can run small FFTs in orthos without errors. I can run large in place FFTs without errors. For some reason though when it comes to the blend test it fails.

Does anyone know why this would happen? Maybe a bump in NB voltage?
