I don't know if anyone has experienced this, but when I went from stock to 4ghz I noticed normal OS activity didn't feel as fast.

So here's the tip...I just found out that adding 100ps IOH skew really helps this, it feels much quicker loading programs.
Sorry if you guys already know this. I just get the impression that most people overclock by just adding vcore and VTT which IMO is just crippling you. If you add vcore when you can fix the bsod by lowering PLL, sure you gain stability, but changing the PLL will let you get more clocks out of your voltage.
To sum up, here are some settings that I've found to help get lower voltages and higher clocks. I can't take credit for most of these, but sometimes it's nice to have everything in one place.
IOH: 1.12v (not a set number, basically just don't turn it up to 1.2v unless you have to. This also depends on your GPU)
CPU Clock Skew: 100ps
IOH Clock Skew: 100ps (I just recently changed this one, so I'm not sure if that's the best for stability. I found 100ps for the CPU was the most stable (@4.3ghz), but I haven't decided whether this helps overall stability or not, I just noticed the OS felt faster)
Current feedback override - enabled. (I don't know if this helps stability, but I hear it prevents the multi from throttling which I had a problem with at one point.)
At one point I had to really tweak with the PLL and IOH to get it stable. Don't be discouraged if changing those makes it unstable, I had to mess with those a lot before I came out with the two settings that worked.
If you haven't already, add 100ps CPU Clock Skew. It really helps stability regardless of your other voltages.
You have no idea how much these settings have helped me.
Before I was at:
193 x 21
vcore: + 70
VTT: + 200
196 x 21
vcore: + 60
VTT: + 80
CPU Clock Skew 100ps
Current Feedback Override - Enabled
That's right, higher clock at lower volts and lower temps. Hope this helps someone.
thank you for this ...it ll help people if you can say which bios you did this with!!!....
and i have a question of my own ...
i m having some sound problems with my sonar x-fi...now i never used a dedicated sound card so if i get a higher quality sound card would it worth the upgrade????(if so when i get another sound card do i still have to install realtek drivers before installing the new cards drivers??)
one last , why do we have to install both realtek and creative drivers ??
