Specs: Windows XP, AMD Athlon XP 2700+ 1GB Kingstonb DDR RAM
Hi, I recently upgraded my old sempron cpu to an Athlon XP 2700+, and my BIOS 'CPU Host Frequency' setting is set to 'By Jumper'. Should I set it to 333 because the processor hasn't increased performance in my pc.

"I recently upgraded my old sempron cpu to an Athlon XP 2700+"

In case you weren't aware, the socket A Sempron IS an Athlon XP. AMD changed the name of the AXP to Sempron after they released the Athlon 64. What was the model number of your "old sempron"?

Despite being advertised as a budget line of AMD processors, Sempron socket A processors are simply re-branded Athlon XP processors

http://www.cpu-world.com/CPUs/K7/TY...

All socket A Semprons (except one) run at 166MHz frequency (333MHz FSB). Your AXP 2700+ also runs at 166MHz frequency. So if your Sempron was running at the proper frequency & you haven't touched the settings, the 2700+ should also run at the proper frequency.

Try running CPUZ to check that your CPU clock settings are correct:

"the processor hasn't increased performance in my pc"

You didn't say what speed the "old sempron" ran at, but if you went from say, 2.0GHz to 2.16GHz, I wouldn't expect you'd see much of a difference in performance, if anything.

BTW, you should have posted in the CPU forum.

I can't run that tool because windows freezes upon login. My BIOS setting is:

CPU Host Frequency: By Jumper
AMD Athlon XP 2700+ (166 x 13)

Are you saying you can't boot into Windows?

I changed the link in my other response. Download the file, unzip it, open the folder & click on CPUZ...it may take a minute before it pops up.

"AMD Athlon XP 2700+ (166 x 13)"

If that's the speed it's running at, 13 x 166MHz, you're good to go. 2700+ is the model number, not the clock speed. And 333MHz is the FSB, not the frequency. The correct speed for an AXP 2700+ is 2.167GHz.

And you should be running DDR333 memory along with it.

Now what is the model number of your old Sempron?

I can boot into Windows, but as soon as my desktop appears everything freezes.

My Sempron model number is: SDA2300DUT3D.

Your Sempron

9.5 x 166Mhz

Going from a Sempron 2300+ to an AXP 2700+ is a 583MHz jump in clock speed...reasonably significant.

"as soon as my desktop appears everything freezes"

Start your system, immediately enter the BIOS, open the PC Health menu & watch the CPU temp. It *should* stay below 40C. If it continues to climb, you didn't install the heatsink correctly. There's two things you have to be very careful about when installling a heatsink on a socket A CPU:

1. you can install it backwards. If you do, it won't make full contact with the CPU core & as a result, the CPU will overheat & possibly fry. Here's a pic showing what can go wrong:

2. you MUST use the correct amount of thermal paste. Too much will act as an insulator & prevent efficient heat transfer, too little (or none at all) will also prevent efficient thermal transfer. You only need to use is a tiny dab about the size of a grain of rice & it should be spread thinly & evenly on the CPU core only. Here's a couple of pics showing how it should be done:

My CPU temp increases from 19C to 60C in about 5 mins.... and there are 3 clips on each side on my socket for the heatsink... Left, Center and Right. It's on the left.

"My CPU temp increases from 19C to 60C in about 5 mins"

Just while sitting idle in the BIOS? Take off the heatsink, you installed it incorrectly.

Yes, when idle in the BIOS. And I can guarantee you that the heatsink is installed correctly.

If it's going up to 60C just sitting there, I guarantee you it's not.

All I can tell you is right now, I'm responding using my Linux system which has an AXP-M 2400+ Barton (1.8GHz) overclocked to 2.2GHz (3200+ equivalent), I've been using it for well over 2 hours & I just did a quick reboot to check the CPU temp & it's at 41C.

It would seem one of us has done something wrong.

Does it make a difference that it's on the left clip not the centre?

And, I've taken the heatsink off, re-applied the thermal paste, and made sure that the heatsink is installed correctly.

Still no difference.

Uh, yeah. Why is it not on the center one?

Because that one snapped.

Plus, it never made a difference with the sempron.
