I have a 2Ghz Athlon which runs at 1667mhz. I noticed today that it is currently running at 1250mhz. What should the settings be please and I'll change them?

not sure mate, try the AMD homepage. might have the setting on there

You are running the bus speed at 100mhz instead of 133.

12.5*133 = 1667 which is what you should be getting

Fancy overclocking your Athlon while your in your bios ?

Watch your cooling, though! Athlons tend to hit thermal runaway without too much effort.

Yep, mine ran at 90'C with stock fan (melt down temp for my Athlon was around 95'C but they can go at below 80'C)...If you decide to overclock read the advice/tips first. Got mine to run at 70'C with a bigger heatsink and extra couple of fans.

How do you know what temperature they are running at? Is there some utility that tells you? Is this specific to AMD processors?

Just curious.

Pretty sure my Intel motherboard tells me various things like CPU temperatures, etc in the BIOS

Chris

I think you can access it in Bios, but there are freeware utilities that you can download that will show you this info without messing in bios setup...I can't for the life of me remember what I used..will re-post when I remember..

But when you're in the BIOS the processor isn't doing anything - how is the temperature then going to be representative of what it is under full load?

Google for :

mbm5

prime95

Download them both, install MBM5 - shows temps etc. Run Prime95 to give your processor a good going over - watch the temps under full load

It's still going to have a current running through it........so will still recod something.....(mine sits at about 35deg in BIOS)

Depending on the motherboard, the vendor may already supply some overclocking/hardware monitoring utilities for use within WinXP etc.....

As for Athlon's and thermal runaway.........don't ever run one without a heatsink and fan. they will ignite. Intel P3's on the other hand, heat up and then slow down.......at least that's what i read on a lab test.

The clock is still cycling even though its not running any applications as it still monitors IRQ etc. I have found it doesn't go up much more than 5 degs under full load...but thats only my PC ( you're better of checking with a utility monitor that runs in windows rather than in Bios) IMHO The majority of the work/heat build up will tend to be done by the Video card if your gaming.

If your stuck to checking in BIOS then I would check the temp when first booted up, give the PC a good work out and then re-check to get a reasonable idea of the increase.

I have no idea - I don't own any computer with an AMD newer than a K6 but I was interested. My laptops (all Intel) have software that controls the fan speed based on cpu temperature so I knew it must be possible - just never heard of utilities that can measure it and tell you - presumably it's actually a processor function to be able to report its temperature.

Well laptops - to refer to my previous post - are continuously monitoring and changing fan speed and it's very noticeable that running a CPU intensive application leads to more heat. I was basing my assumption on that.

And it certainly won't be games generating the load. Pah! :eek: :grumpy:

I think its just a set of thermocouples built into the motherboard never really bothered to look though.( Mines older than Noahs boat)

If it has an Athlon processor it's a good few years newer than mine!

Back in my yoof when I was overclocking, I used to clock it as high as it would go and still boot, and then when Windows invariably crashed, I'd check the temp in the bios and then back it down a multiple. That was back in the days of dip-switch and jumper overclocking though

Chris

You mean there's a different way now? :eek:

Never seen anything more sophisticated than jumpers, myself.

If I remember correctly all you needed to do on older AMD chips was solder between two pins (on the top..not the legs !) of the CPU and this allowed you to overclock until your motherboard reached its limits.! I think AMd got wise to this and altered the CPU with an anti-overclocking layer ?

I think I prefer the sound of jumpers! :eek:

Yep can all be done in the BIOS now on these new fangled jumperless motherboards

Yeah, pretty sure there's a thermocouple which sits under the processor...will have a butcher's at a board when I get a moment.

Hope that's not my board you'll be butchering :eek:
