CPU Clock speed confusion

U

USMC68

Junior Member
Hello,

I am new to these forums so please be patient.
I just built a computer with the following "major" components:

2.5 AMD XP+ "Barton" Processor
ASUS A7N8X Deluxe Motherboard
2 sticks (256MB each) of Kingston 400Mhz Pc 3200 Cl2.5 memory
ATI Radeon 9500 Pro Video card
Windows XP Professional

When I boot the machine and go into the Bios it tells me the processor is running at 1.83Ghz. How can this be if it is a 2.5 Ghz processor? How and what do I change to overclock this processor?

Thanks for your patience

The 2500+ refers to the "rated speed", which is basically a naming scheme used by AMD to make their processors more directly comparable to Intel's speeds. In other words, AMD's 2500+ should be roughly equivalent, speed-wise, to a 2.5 GHz Pentium 4.

However, the 1.83 GHz is correct. The 2500+ Athlon actually runs at a true speed of 1.83 GHz. There is no problem at all with your processor/motherboard.
 
Thanks for the help. I will check and see how I can overclock this puppy!
Thanks for the alias boost :-9

And yes I did serve 8 years

Just a correction. AMD never rated it against a Intel platform... ever.
Just on a non-existant T-Bird processor that is supposed to run at 2.5GHz in USMC68's case.

I stand corrected. Stupid mistake! Something that I knew, but for some reason it was buried deep within the bowels of my memory and an incorrect explanation came out instead. Thanks. 🙂
 
I have a question about a new mb I just bought. I hope you guys don't mind a few quetions. It's an Asus A7V333 rev. 1.04. I don't know if I can run 333 on the fsb or if I have to go with 266. Can you help me out here? I'm trying to decide between a 2400 and a 2600 model 10.

You really should start your own thread for this. 😛

Make sure you flash the BIOS to v1017 (or whatever's newest) on your A7V333, or you won't get the 1/5 divider. Once you've done that, you *should* be able to run a 333FSB chip no problem.

True only "in the beginning"...then later AMD "has published" that their PR ratings were also comparable to the Intel P4s. And that still stands currently.

I had prob understanding why AMD does things the way they do..i have the 2.5 barton and yes its a 1.83..its becuase AMD rates thier CPU for what it can compete and go up againts..instead of what its actuall core is ..this allows them to sell "fast" CPU's for cheaper....they make a CPU clocked at 1.83 but wehn tested they perform like a 2.5ghz....Confusing!!!
 
If you do an internet search you will find that not all megahertz are created equal.

AMD sells a 1.83 gig CPU (the barton 2500+)

INTEL sells a 2.5 gig P4

The two CPU's are reasonably comparable. The two CPU's have approximately the same computing power. Each CPU has its own specific strengths and weaknesses but over all they are reasonably compaired to each other.

Despite AMD's claims that it is comparing to a T-Bird 2500 we can all take note that a T-Bird 1400 is roughly the equalivalent of a P4 1400 and so a T-Bird 2500 would be the rough equilivalent of a P4 2500. The reason for such "mis-leading" speed claims is the fact that a 2.5 gig P4 does not have as much computing power as a 2.5 gig Athlon. It has roughly the same computing power as a 1.83 Athlon with a 512 kb cache (the barton).

INTEL has designed a CPU that ramps to very high clock speeds but does not do as much work with each clock cycle as AMD does in the Athlon line of CPU's. AMD has designed a CPU that does not ramp to higher clock speeds as easily as the INTEL P4, but does more work with each clock cycle. In order to appear to the ignorant public as offering a comparable product AMD has gone to the Power raiting to compare CPU's.

INTEL's marketing of raw clock speed is misleading. AMD's marketing of Power raitings is misleading. If the ignorant read both sets of marketing claims they will assess the two competing CPU's on an equal basis and will reach a reasonable buying decision.

Forgive me I know that the AMD specification is not truely the ol;d power raiting system but the term works well in an explanation.
