What did I do wrong in this OC?

In my bios there is an EIST feature which lowers the multiplier when the cpu is not in use or in very little use. Run prime or any application that uses some of your cpu and I bet that your 6 multiplier will instantly clock up to 8.5x. This feature saves power when cpu is idle or near idle.

Your prop tab reads your default cpu clock and then the latter is your oc clock. You have it oc'd to 3.4

Also, I see 3.25gb of ram so we know you're running 32 bit xp

In BIOS you need to disable EIST and C1E. C1E is the one that lowers Multiplier, EIST lowers the FSB

I've never used them since I like to OC and every time I had them on comp crashed. I also have not looked to find what kind of energy saving they give, so I can't answer the energy saving question.

yeah it's mostly the C1E and EIST I had the same prob but I just left the clocks same and oced the video card instead

C1E and EIST only lower vcore and multiplier but on different terms. One based on the halt instruction (C1E) and the other based on current system demand(EIST). The FSB in these operations are never affected since you're lowering the multi and vcore already to get the lower clock.

EIST is a more enhance "end result" than C1E. C1E is an either off or on sort of multi underclock where the feature is either being employed or not used based on an idle system. EIST theoretically can throttle a system depending on the current demand placed on the CPU, this is why I sometimes see my cpu stay at 6x multiplier when surfing or using other low demand apps. Also, EIST is supposed to be able to up the multi as the demand increases, but your system needs to be aware of speedstep for this to work.

Hope this helps. Oh and the OP, I could read you were using xp but I also read your system was only showing 3.25. This is because of the limit that a 32 bit OS has in only addressing 4gb total of physical ram.
