What does the J mean?

[Randhart]

Hey there,

I have been out of the hardware thing for a while, been traveling for 4 years. and have just got myself a New PC with a P4 540J chip in. I was just wondering what the J means?

Cheers!

J means it has the No-Execute capability that helps prevent some types of buffer-overflow attacks (virus/worm type of stuff).

Thanks for that ...

Another thing, Why is it that when I look at my system preformance it display's two graphs in CPU Usage History? Does it have something to do with HTT? I know I can turn it off and only have one .. but it Looks cool 🙂

Cheers!

Why would you want to turn hyperthreading off? If you are being serious.

Yes, HT makes the OS see it as two virtual CPU,s

I meant I could make the Display on the Preformance monitor display only one graph ... don't want to turn the HTT off.

I'm not sure if that can be done.
