Is this normal or did I get really lucky?

[Staz]

I was able to overclock a mobile XP 2500+ CPU to 2400MHz(12x200) at DEFAULT voltage! Is this pretty standard, or did I get lucky in the overclocking ability of my CPU? Also, if I want to take it higher, how would I know when I need to bump it's core voltage up?

At 2400MHz, about how similiar is this CPU's gaming preformance compared to a A64 2800+?

What are you calling the default voltage? The default voltage for the mobile chips is 1.45v, but some motherboards think that's a desktop chip and default to 1.65v (the stock voltage for non-mobile Barton CPUs). If that's the case, then 1.65v seems about average for 2.4Ghz.

You know, I never did check my voltage, just never changed it figuring the mobo would set it at 1.45v. It might have been set at 1.65v from the start, will have to look into that.

Good for you. My standard Barton 2500 'only' does 11 x 200 @ 1.75V.

Both of my boards set the default voltage to 1.65 with my mobile. 2400mhz is good. As far as going to a higher speed, just bump up your multi or fsb and if it needs more volts it will either not boot or be unstable in windows(prime,Super Pi,etc..)

I'm running my 2700+ XP @ stock speeds at 1.6V, .05V lower than stock. It runs fine. I can also OC to about 2500MHz with just a .05V bump up (but my NF7-S undervolts by about that much, so it'd be closer to stock really 😀)

Interesting, my NF7-S overvolts by .04V

I've got two 2400 mobiles here; voltages are the range reported by MBM5:

2.3GHz, NF7-S rev1.2, 1.70-1.8v, 1.35v default (35W model)

2.0GHz, NF&-S rev2.0, with Mantaray D26 BIOS, 1.55-1.65v, 1.45v default (45W model)

So your 2.4GHz seems pretty good; must have gotten quite a nice chip there. Maybe you'll get 2.5GHz with a bit more voltage. I don't know if I'd take a mobile CPU over 1.75V, but that's just me. Some people at the Xtremesystems forum are running their poor mobiles at more than 2.0V.

Where do you get alternate BIOS'es for the NF7? I've also got a V2 and wouldn't mind some new BIOS goodness!

 

[Staz]

Well it looks like my board set the default voltage to 1.60v, which would explain my OC ability.

You've still got a great CPU I would say. You have a bunch of headroom left. I can get 2400mhz on my desktop 2500, but it runs too hot and any less voltage than 1.8 won't run Prime95 for more than an hour. Maybe I'll get a better HSF.
