Amd Nx

[ignitionxvi]

Hey guys,

I have SP2, but i don't know how to turn on the NX support. Anyone know how?

 

[Liam]

I think it's enabled by default... not sure though. I couldnt find anything googling.

yeah, it's enabled by default for "essential" Windows programs and services only. http://support.microsoft.com/default.aspx?kbid=875352

you'll get this message from a poorly coded program or virus:
Data Execution Prevention

If mine isn't on by default why do I want it on what does it actually do?

your's isnt on because your processor doesn't support it.

Do ClawHammers have nx btw? The "CG" ones.

 

[blue_heart71]

only amd64 cpus support nx

i'mm pretty sure intel put nx support into the nacona... not sure on the specifics though

 

[Liam]

I'm pretty sure they did too...

all the prescott family will get NX (or XD, execute denial as intel calls it) with the E0 setpping.

But neither the Prescott or Nocona D0's have it.

Yep.... and that's why at this point, I would not recommend any non-Opteron CPUs for servers.

I thought Opterons were the first to have nx? And i'm still not sure if CHs have it or not.

 

[defakto]

For whoever asked, the NX is supposed to be able to prevent buffer overflow type attacks.

did you read the above posts? all the AMD64s have the NX function, and i think even the sempron will offer this function too but not sure whether all sockets type or only the 754

again, all AMD64 cpus have NX regardless the code name, but dont forget, you need to install winxp sp2 to have it working.
