overclocking help!

[gammite]

hello folks,

does anyone know what it means when after you overclock your AMD the chip is represented in MHZ instead of the number of the chip at the boot screen?

for instance, if i push my xp 2500+ up to a certain point at the boot screen it will be represented as an AMD XP 19xx MHZ. If i leave it at stock FSB or only overclock it slightly it will say xp 2500+.

can anyone help me here???

If the Multiplier and FSB settings do not match an AMD processor PR type defined in BIOS, most BIOS default to reflect the actual clock speed.

Calculate what the MHZ is in respect to the legitimate speeds. I don't think there is a 2700, or a 2900, so it could hardly read as one. You might have hit a speed unintended and uninterpreted. Hell, you might have a 31 or 33!!!

What he ->>> Ripper2860 <---- said.

What is your motherboard? . Get BIOS update.

What Ripper2860 says is true.

This sounds like your motherboard is being smart about things. Mine knows that the only chip to have an external frequency higher than 166 (when it was made, anyway) was the XP3200. I have an XP2500, same as you. As soon as I push this 1MHz above standard speed, it POSTs as an XP3200.

You motherboard could be recognising a non-standard chip and reporting the actual speed, as opposed to guessing what it could be.

The only other possibility is that your motherboard does not support higher than FSB166, but by the time you are overclocking, this assume this is untrue.

However, I do not see why you would need a BIOS update. Your overclock is working successfully, why mess with the BIOS?

i have a gigabyte K7 Triton 400 (GA-7VAXP) motherboard.

so to make a long story short there is nothing wrong when the boot screen is showing in MHZ vs. the actual chip number??? can anyone confirm this???

at this point i have only overclocked slightly. at one point i set the FSB to 180 and got a clock speed of 1.99 but i backed off because this is when i noticed the boot screen discrepancy. i currently have it clocked to 1.902 at a FSB of 172. at this level the boot screen states 2500.

i'm pretty sure i have a locked 2500 because i can not access the multiplier in the bios and the chip is green vs. brown. otherwise i would try a couple of other things. by the way i believe my multiplier is set at 11 as 1902/172 gives me 11.06.

thanks for the help!

Your Barton is indeed locked, but the colour has no bearing on the chip itself. I built my new machine two weeks ago, and I was more than a little surprised to see my nice new Barton was green and not a nice brick colour.

If your chip is having trouble with stability at higher speeds, why not try increasing VCore a bit? This generates more heat and increases wear on your CPU, but does give more stability.

I will be posting up an overclocking guide/information page shortly, as soon as the University creates my webspace. If you still haven't achieved the overclock you want by then, it's all yours.

thanks cobra.

i have yet to run into any stability problems. however i am only trying to push my chip to to the 2.10-2.20 realm. i already have my 2400 on another computer overclocked and stable at 2.20 with a FSB of 152 or something near that. i can't remember exactly.

looking forward to your guide!
