AMD sempron...need to overclock?

[ursukyoung]

I just got an AMD 2400 sempron.
Its speed is 1.66ghz.
I was wondering am I supposed to overclock it to 2.4ghz?
Or does the chip running at 1.66ghz, give the same results as a P4 2.4Ghz...

Just a confused user~

Thanks ahead~

2400 is its PR (Power Rating)

it bassically means that compaired to an old athlon (not an Athlon XP) the old athlon would have to run at 2.4GHz to match its performance.

so its not necessary to overclock it.

the 2400 is just a number, and the actual cpu speed is 1.66Ghz...

correct?

thanks~

Right.

The PR number mistyriously matches the Celeron. The PR numbers to the AthlonXP used to be base, well pretty loosely, on the P4, but towards the end they were just pulling numbers out their buts. The proccessor would not ramp up and Intel was leaving them eating dust. The Athlon64, on the other hand, lives up to the PR muber MUCH better.

You could overclock it if you wanted. 2Ghz should be easy, even with stock cooling and voltage. You might see 2.2Ghz or more if you are lucky.

if i overclock it and its not compatible, it will just not boot right?

no harm if i reset, as long as i don't try to force it at that speed again and again right?

and lastly, i have a shuttle mb MN31L, how do i overclock? go to setup~

The should be something in the BIOS to let you adjust stuff, but if you take it in small chunks the system will just become a bit unstable in some applications. I used to use Quake3 and 3DMark2001se to test stability. Some use Prime95. My new one is Doom3 and 3DMark2005.

where can i get a copy of 3dbenchmarks?

3DMark is made by FutureMark (used to be called Mad Onion):

If you have not seen them, I'd download 2001, 2003, and 2005. They look pretty cool. They also give you a 3D score at the end for how well your system performed called ORB. Some people drop image quality to raise speed, so you might be a bit lower than the average for a similar system. The last 2 are very video card bound, but the 2001 likes a good CPU too.
