Do Intel dual core CPU's need reghacks and drivers?

[Aenslead]

Hello all.

As you can see in my signature, I have a Pentium D 805 @ 3.33Ghz.

I was wondering if I need the reghack and a special driver or MS parch for my setup to work at 100%, like AMD CPU's do?

Just for the fun of it, I tried the /usepmtimer - boot.ini thing, and I swear I feel my computer much more responsive - maybe I'm just imagining things.

Do you suggest adding the MS Patch? I already have WinXP XP2, and as far as I know, Pentium D 8xx don't have EIST, so power managment is off-question.

I appreciate your responses. Ciao!

If you experience no problems, dont patch anything. I dont have that patch but only the CPU "driver" from AMD and /usepmtimer in boot.ini and never had any problems. Though, I dont have CnQ activated anyway, which usually also solves the problem for many people, since its just a problem with the p-states.

Edit: I think that MS patch requires you to have CnQ to do any good, so its pretty much limited to AMD machines anyway - might be wrong though, as mentioned, I never installed it.

Pentium machines have their ow version of CnQ, speed step i think its called.
Also from what i heard the ms patch is only needed if ur planing to use CnQ or speedstep

The amd driver is required, before i instaled it i had weird lag in games.

The microsoft hotfix is for all dual cores, not just AMD. I actualy haven't had to use the hotfix with any of my dual cores, why fix what isn't broken.

Weird thing is, that when I run Sisoft Sandra 2k7 Arithmetic CPU Test, I get REALLY low Whetstone iSSE3 scores compared to other Intel processors, whereas Dhrystone ALU I get higher scores than comparable speed processors.

I find this quite odd. BTW, do you happen to know what exactly the "/usepmtimer" does?
