"Visualization Technology", "Execute Disable Bit" and "Speedstep"

Hi,

I've come a little stuck at the 3.4ghz oc phase of my E6600, and I read that disabling the: "Visualization Technology", "Execute Disable Bit" and "Speedstep" should improve stability?

I did this whilst at 1.435v Vcore and tire dOrthos again, but it still crashed? I then tried uping my NB Volt to 1.7 and that also didn't solve it. So I then uped the Vcore to 1.450v and I am currently 11mins into orthos... so better than before.

So I just want to know, shall I put them back to thier defaults (All but SpeedStep where enabled, SpeedStep was already disabled)? Or do they screw up ocing and not make any difference? If so I'll leave them off?

Anyone?

Speedstep should always be off when overclocking, it lowers the clock speed when your processor isn't doing anything demanding, which obviously defies the point of overclocking.

I'm not sure what difference either of the other two settings would make though, if any tbh. :confused:

ok no worries tute, maybe someone else knows about the others?

I've got them off at the mo, and i am 33mins into the orthos test... so its gone much better than before.

I'm gonna leave it running all night at 3.4ghz, then try for 3.5 tomorrow!

But i would deffo like to know bout those other 2 options beofre I do, so if anyone knows that would be cool!

true but it automatically clocks back up on demand so personaly i dont see any down side to speedstep.

i have an o/c'd machine but i dont need it running at full speed when idle/doing menial things (like web browsing) so clocking down = good because less heat.

Good for the power bill as well

Deffo off for all three.

Note that you need to boost the CPU VTT voltage to 1.55 (or higher), if you have that setting, for maximum stability. By experience of the Asus P5N32-E SLI at least is that you will probably need to raise the northbridge and 1.2HT voltages as well at some point.

Execute disable bit is a form of hardware virus protection, and by visualisation do you mean virtualisation technology?

I only have control over 4 voltage settings, and thats Vcore, DDR, Northbridge and vcore offset voltage.

I wanted to up my 1.2HT and VTT as I heard they will improve things, but when you dont have the option you cannot do that... is there anythiing esle I can do? I am having much problems getting over 3.4ghz... im on 3.5ghz at the moment but I have the vcore at 1.525v and thats as high as i am prepared to go on vcore. I had it at 1.5125v before, but orthos "STOPPED" after 1hour 40mins. Im 12mins thru orthos on 1.525 now, and if it dies again then i will have to go to 3.4ghz, which i dont want to do... 3.5 is the speed I want and no faster!

I may have meant that Defcon... Im not sure? More than like I meant that, I looked at it quickly in the BIOS... and I dont have it in my mobo manual as that option isn't in there, yet all the others are?

Try the northbridge next. Not sure what Vcore offset is, but try it anyway. If it doesn't work, just put it back again. But adjust each in turn, not both together.
