whats goin on!!!!!

[AGENT 47]

i have checked on my processor speed on a number of occassions,and nearly every time its changed.i originally thought it to be 2800mhz,then sometimes i look on my system info,and its 1250mhz or 1005mhz. whats! all that about.
please reply.

What are your system specs? Many laptops have a battery saving feature to slow the speed of the CPU when the full power of the CPU is not needed. I don't know if that applies in your case, but a thought.

The mods may want to mave this to Core Hardware.

[AGENT 47]

hi jlreich, have just read your reply,my sys specs are - AMD athlon 2800mhz? processor,80 gig h,drive,512mb ddr ram,radeon 9200 128mgb, pc chips motherboard ddr-400,fsb 400mhz. on win xp pro. AGENT 47.

[jlreich]

Hi AGENT 47. A little more info please. Is that an AMD 2800+ I take it? What brand and model# is your PC? I take it from the specs you already gave me, it is a desktop, not a laptop?

[saphalline]

You must have an Athlon of some type with a 2800+ model number, because there is not yet an AMD CPU that runs at 2800MHz. Even the vaunted FX-55 only runs at 2600MHz. With a 400MHz FSB, it sounds like an Athlon64. So, the 2800+ Athlon64 runs at 1800MHz.

This doesn't quite explain why you're getting many different CPU speed readings, so what are you using to check your CPU speed? Try using WCPUID (http://hp.vector.co.jp/authors/VA002374/src/download.html), just click the top link labeled "wcpu330.exe" to download the latest version. Run that and report what it says.

Hi,Saphalline,thankyou for the reply.
i have used the wcpuid & it reports that i have a AMD athlon xp model 8 1250mhz.
for some reason i used my system properties last week, & it reported that i had a amd duron 1050mhz. weird? or what.

[saphalline]

That is weird. What chipset does your mobo use? Or if you don't know that, do you know the model number of your mobo? I ask because it's likely that your mobo just left the FSB at the stock 200MHz and not to the correct FSB speed for your CPU. But it's also possible (however less likely) that your chipset can't properly support that Barton 2800+ you have there. The proper speed should be 2083MHz on a 333MHz FSB using a 12.5x multiplier.

HI, SAPHALLINE,

i have a pc chips M484ALU motherboard with 400fsb

Alrighty now, ;)
I can't find anything about your mobo either by Google nor the PC Chips main site. Why is that? Is it a propietary pc? Otherwise,

'One' thing comes to mind (I'm a singular person...:o), you've been trying to fix it for a bit now. Have you set it to default in BIOS? That could end up entirely not how you want the CPU set up as, nor your memory clock setting. It usually ends up without getting the maximum capabilities of the processor but at least a safe place to start diagnosing a potential problem. Esp, when heat is an issue.

In my case, if I defer to defaults, I end up with less processor speed AND less RAM speed in mhz's. So watch out when you need to set your BIOS settings to 'default' and don't just do it as the mobo is brought back to it's optimum levels either. We'll just get confused when a step back (in thyme) occurs...

Oh, and HL2? Well I'm in my second half now...

BTW,
1999.77 MHz sounds about right for an Athlon 2800 to me, my 2500 is only supposed to be 1800mhz when correctly set up.

[saphalline]

Ok, your system is a little confused because, somehow, the BIOS got set for a higher FSB than what your CPU can handle. Or rather, what it's supposed to handle. This would explain why your system as a whole is a bit confused.

A model 8 AthlonXP with a CPUID string of 681 should run on either a 266MHz or 333MHz FSB. The name string for your CPU is "AthlonXP 2400+", and I wasn't sure until I saw this that I realized why the 12.0x multiplier was out of place. The 2400+ is only supposed to run at the slower 266MHz FSB, for a core speed of 2000MHz on a 15.0x multiplier. However, when run at a higher FSB, most Socket A mobo's will restrict the CPU's multiplier to 12.0x thereby preventing the CPU from running too fast and possibly overheating. It's a built-in safety measure. If you really try and run a CPU too rough, some mobo's will bring the multiplier down to 5.0x, making darn sure that the core speed won't be too high! :p

I don't know how the FSB got to 333MHz, but go in the BIOS settings and bring it back down to 266MHz where it should be. That should also bring the mutliplier back to 15.0x. And on that note, your CPU is certainly a 2400+, so if you were mislead into buying a 2800+ (were you?) then I would investigate this!
