Athlon 2400+ Speed?

[deepakvrao]

Hi,

Bought an ACER 1353 which has an Athlon 2400+ M processor. When I open system properties it shows the correct Athlon 2400+ processor but it shows speed at around 796Mhz. Any idea why? The dealer said that it is something like a lower speed used when processing power used is lower in the M [mobile] Athlon processors. Is this true? and if so how do I get full speed when I need to do intensive work like photo editing etc?

On a desktop board that shouldn't be happening since most boards don't support those features. I would make sure your FSB is set to 133Mhz in the BIOS.

wouldn't be surprised, my p4 1.7-m downclocks to 1.2ghz and 700mhz

From AMD:

"The mobile AMD Athlon XP-M and low voltage mobile Athlon XP-M are designed to extend system battery life using the most dynamic power management technology, AMD PowerNow! technology."

nothing unusual with your cpu speed, same thing as intel's speedstep..some laptops allow you to set it to run at full speed all the time

Its not in a desktop, its in a laptop. Can I set the speed higher?

 

[Special1Sauce]

It should be check your Manuals etc

Maybe you can set something in your BIOS to not use the PowerNow! feature. However, when you need more power from your CPU, you will get more power from your CPU. You don't need to do anything.

If you want to check to be sure, I'd imagine this would work: run CPU-Z or WCPUID then run Prime95 (or any cpu-intensive app, encoding .mp3's should do), hit refresh on cpuz and it should show it's cranking away at full whack.

Out of interest, would a XP-M 2500+ run in a Nforce2? Unlocked and uber low voltage sounds awfy nice for some reasonable overclocking and keeping a particularily quiet PC (esp. combined with e.g. Asus QFan). I'm assuming a stock XP-M 2500+ wouldnt have any slower performance than a 2500+ Barton?

It might be slightly slower because it natively runs on a 266Mhz bus compared to the desktop 2500's 333Mhz bus. However even if you clock the bus to 333Mhz your processor would already be running at 2.3Ghz! That would more then make up for it.

ta, though mine be better to get a 333fsb 2500+ up to 400 I guess.

In power managment set it to Desktop computer and it will run at full speed all the time when it is plugged in.

The only thing that will do is waste battery power. Like most other notebooks, the extra speed will kick in when you need it. Relax and enjoy your new notebook.

The extra speed does not kick in when I do processor intensive tasks and I found out that Win xp processor driver does NOT support Athlon XP 2000 and beyond and a new driver has to be installed. I've downloaded it but am unable to install it. Will try over weekend

If you're using WindowsXP, it seems that the speeds of mobile AthlonXP processors is reported wrong in the system properties dialogue box. You can go to System Information (Start -> Programs -> Accessories -> System Tools -> System Information) and scroll down. This dialogue box should report the correct frequency of your processor.

It is running slower because the mobo detected the "default" fsb and multiplier, which is LOW for mobile chips. Just manually set the fsb and multiplier in your bios, it will be perfectly fine. I have a 2500+ mobile, and the same thing happened to me, and everyone else who use Mobile CPUs.
