CPU Weirdness - HELP!

hey kids. Over the last couple of days ive been getting some weirdness with my q6700. Its not overclocked, its all at stock settings (although ive a tuniq tower fitted for future overclocking). The rig is six months old and has been fine mostly in that time.

A couple of days ago I rebooted and the machine hung at POST screen. i left it sat there to see if it sorted itself, but five minutes later still nothing so i reset. it did it again. then i noticed it was reporting a processor speed of 1.59mhz!!!! wtf??

Its a striker extreme (i have 1504 bios) which has a helpful CMOS wipe button on the mobo, so i shut off and wiped it. it rebooted fine and picked up the speed correctly. Strangely tho, ive been sat here with CPUZ running for a half an hour and it keeps flitting from 1.59mhz to the correct 2.6mhz. it stays at 1.59 for seeral minutes, changes to 2.6 for a few seconds then goes back to 1.59 for minutes.

Ive had varios blips and glitches with the striker extreme and im the verge of changing it tbh. does anyone know wots going on here? i havent fiddled at all in the bios so it cant be a borked overclock - in anycase, i reset the cmos to factory setup so something weird is definatly goin on.
 
this a bios setting, dont know what called on the asus board, on mine it called "eist"
when enabled , that's why you seeing drop, just really a power save option, but as soon as cpu starts working u will get your full 2.6 :)
easily fixed in the bios. nothing to worry about there m8 :)
 
cheers. ive tested the theory but running photoshop filters and watching cpuz at the same time. you seem to be right, it does drop down to 1.6 when its idle.

thanks mate.
 
Doesnt even need fixing, speed step reduces the cpu's power requirements, and lowers temperatures (and electric bills) when the CPU doesnt have any work to do. As soon as there is work, it takes a single clock cycle to restore the processor to full speed. You really cant tell the difference in performance between a chip with speedstep on, or off.

The only time speedstep really needs disabling is if your overclocking to the extreme and the cpu crashes when it lowers the voltages during speedstep. But for modest, and even quite high overclocks speedstep is still generally "safe".
 
i realise now it was a stupid question. its only started happening recently (ive updated my bios in the last few weeks which would have defaulted all settings back to factory) and im sure i previously disabled features like this so that explains it. feel a bit silly now!

however - it doesnt explain why it was failing to POST with a speed of 1.59. oh well.
