Question about speed step and overclocking

Building Candy · 8 Mar 2007 at 11:07

Im soon to upgrade to a E4300 on a DS3, im hoping to clock it to 3ghz or just under. I see a lot of threads saying to turn off speed step and the other power saving stuff in the bios, is this because you cannot overclock the chip with it on? My pc spends a lot of time sitting downloading, seems it'd be good to have it slow down and run cooler/quieter when its not under load and then speed up when i start working it?

I have an E6600 on my P5B-DLX, running at 3.6ghz.
I used to have C1E off in the bios, but now leave it Enabled.
It still overclocks the same and works fine

Multiplier goes to 9x for 3.6ghz when needed and drops to 6x for 2.4ghz when inactive.

so why the need to turn all the power saving off? why do people want it running at full speed all the time?

When you use the powersaving features in intel it overrides the voltages that you set so if you bump up the vcore for a good overclock, e.g. 1.325 - 1.425 for a E4300 @ 3Ghz, enabling the power management puts a lower voltage through and it crashes.

You can get away with a little bit on the ASUS P5N-E as that has a +100mv option though that mainly compensates for vdroop.

Oh right, so it drops the voltage and the multiplier? is there not a setting so that it will just drop the multi and keep things stable in either state?

My voltages are reported, when C1E is enabled, by Asus Probe and Cpu-z as the same as when C1E is disabled....no voltage drop.

lol, well one of you is wrong :rolleyes:

come on, someone must know

On my Abit, as soon as I touch the voltages, speedstep is disabled in the BIOS.

With the previous P5N-E, I left speedstep enable and discovered it was orthosing at 1.28v vs 1.325v core rating. Upped the voltage in the BIOS and still got 1.28V

speedstep and c1e have no effect cause i just tried them both since im trying to overclock atm. System is crashing running orthos with 320mhz fsb at default voltage after 1 1/2 minutes. Ill try all other power management options. I thought the e6600 would be able to goto 333mhz without any voltage changes?

Most do on stock but sometimes you get a rotten core, could be your memory or something else though tbh.
