Strange one here, hope someone can help.

Running E6400 on DS3 V3.3

OC at 3.2 nice and stable, Temps 25-29 idle, 56 loaded. Vcore 1.35

When I push FSB to 425, Vcore 1.4, speedfan, orthos & TAT all report that there is only 1 core in my processor.

Sometimes its fine other times it reports only the one.

Any ideas?????:confused:

mch would be your northbridge voltage, uping that will able you to raise the fsb more, intel chipsets love the extra voltage. it's probably instability that's causing only 1 core to show up. uping the vcore if you can might add stability, otherwise you'll want to back down.
