cpu not running at full speed

[angoladantana]

I have an asus a7n8x motherboard and an amd 2500 barton and pc 333 512 ram. at the most stable setting the processors shows up as an amd 1900

Check in the BIOS to see what the FSB (or system bus speed) is set at.

The AMD Barton 2500 Runs at around 1833Mhz.

amd has a deceptive marketing campaign to confuse non-computer people. Your computer is running at the speed the processor was designed to run at.

I don't think its neccessarily a deceptive campaign. What Amd does is it tries to state that a amd chip named lets say 2500+ will run equivalent to a Intel 2500 (if there were one.) You have to remember that the number alone is not the only thing that determines the computers speed. (throughput)

That is correct, the AMD CPU does MORE per clock cycle than the Pentium chip, which is why an AMD 1.8GHz (which is an XP 2200+) performs as well as a P4 2.2GHz, because they are basing their numbers on performance.

Just a little insight to why they are doing what they do!

Cheers!

It's not deceptive, but it's not always accurate either. An Athlon 1700+ would blow the socks off of a P4 1.7GHz, no contest! But an Athlon 2600+ barely stands up to a P4 2.6GHz (533MHz FSB).

As we move into the higher speeds, AMD's naming scheme becomes more obsolete and inaccurate.

There is a reason why the 1700+ beats the s$!# out of the P4 1.7. The ratings are based against the P4's with the Northwood core, which if they made a 1.7GHz Northwood P4, that would be roughly the same performance as the XP 1700+.

The P4's under 2.0GHz were all made with the much weaker and inferior Wiliamette core; and such are not a direct comparison to AMD's performance rating.

I do agree with the performance rating being very agressive; to me it's almost seeming that they're basing the rating partially on what price level they want to sell the cpu at. I could be wrong, but it's a pretty interesting comparison.

 

[cdogg]

Yes, AMD's rating against pre-Northwood P4's is hardly fair to Intel. However, the Northwood wasn't released until the 2.26GHz model was available. By then, AMD's rating scale had been around for more than a year.

So, you can't say that AMD wasn't targeting the Williamette models. It's obvious they were. They knew that the 1700+ model was actually performing closer to the P4 1.9GHz model. It was to their advantage to slap on a 1700+ rating rather than 1900+, because it allows for more headroom to compete with future CPU speeds.

However, that headroom is gone and now AMD's rating is over-agressive. Their new 3200+ Athlon, for example, barely competes with the P4 3.06GHz and would be better paired up against the P4 2.8GHz model.

make sure you have the latest bios revision for your motherboard. Im not sure about yours, but i have seen that older bios versions cant "read" the faster amd xp cpu's. Not a problem, just get the latest revision and flash the bios. all should be good.
