Reworking the CPU can increase performance, but finding ways to unlock multipliers is another challenge.

Robert Cook :
what actual speed will it be? 400MHz sounds like a slowdown to the real rate.
400 is 800, and memory moves data during the rising and falling edges of the signal, which means double data rate. 400 equals 800. Some programs might show 800, but it doesn't actually affect anything.
See Double data rate @ Wikipedia for details on this topic.
For more confusion, look at the GDDR5 used in graphics cards. You might see a card running at 1753 MHz but delivering 7ghz.
Check out GDDR5 @ Wikipedia.

^ I’ll be waiting... This would be nice to try, as I’d like to have a chip that can match my AMD phenom II X4 965 BE, which I got for free.
Now I’ll be around to comment and keep posting, including all day tomorrow. Do you own an AMD phenom II X4 965 BE in a Dell PC, or did you build your own with it?
Second question: Are you using an NVIDIA GPU or an AMD one?
Lastly, for now—have you ever reinstalled your operating system (which version do you have now)? If yes, have you used the Dell copy? If not, did you install Dell Utilities and/or diagnostics after the reinstall? Why am I asking these things?
Well, I recall now (after finding one of my old posts) that a partner of mine, who was working on overclocking a Dell Inspiron 570, used an ATI Catalyst to try to boost his CPU. It worked, even if not as well as my AMD Overdrive setup. I also remember that earlier versions of nTune allowed CPU overclocking.
I decided to check the post where someone mentioned they could overclock their XPS 720 using nTune (there might be BIOS options for overclocking on that model, so it could still apply). I thought it might be possible.
[strike]What version of nTune old, (I think this feature was disabled in newer ones) and what AMD Catalyst is doing, is raising the CPU voltage.[/strike]
EDIT. During overclocking there’s also a rise in voltage, but it isn’t well managed and Dell motherboards aren’t very robust.
You can’t attempt this on the original Dell OS or installation, or if you installed any Dell utilities, because I found out Dell is restricting overclocking even at the software level.
So once my partner and I reinstalled using Microsoft copies and didn’t load Dell utilities, we were able to overclock our Inspirons at the software level.
It’s worth noting, especially if you’re an ATI user (I’m an NVIDIA person).
I’m still figuring out my last links on tape mod, as many of the old links are no longer working, which is why it takes so long.
Ask the public directly, if OP raises CPU voltage (including via tape mod) mechanically, would this affect CPU speed? Would it be stable? It depends on Dell MOBO.
Some people wonder if changing the CPU voltage mechanically, like with a tape mod, would affect its speed. Would it work consistently? The answer might depend on the specific Dell MOBO model. Generally, higher voltage doesn't speed things up, but overclocking usually requires more voltage for stability.
