I just ordered a new system, Im no noob at building or O/C'ing systems, but I've never used the mobile desktop replacement chips before. I got an A7N8X-E board, 512mbx2 corsair 2.5-3-3 pc3200 ddr for dual channel, and an amd athlon xp-m 2500+. I'm aware this chip runs at a lower vcore than the desktop, but what sort of settings in the mobo bios should I be messing with to make it stable at 3200+ speeds. I don't really care to push it farther than that. I have the thermalright SI-97 heatsink and a vantec tornado 92mm fan w/ a vantec nexus controller, so I don't think cooling down the cpu is going to be an issue. I also heard there is some special bios for this board that lets you do some other o/c timings and stuff, any truth to this rumor? I tried to search for mobile xp and xp-m and a few other terms, but had no luck finding anything specific (I know from other forums that the search button is a life saver some times ) Thanks for any hints or advice you can supply me.

The lowest voltage, stable 3200+ speed, I have gotten on a 2500+ M, was 1.525v @ 11x200 on a NF7-S.

Try that.

The SI-97 is a great heatsink, (I have an upcoming review on it.) it will handle the heatload with ease.

As for a modded BIOS, try one of these.

Here is what I have used for my Mobile 2500+ with the same HSF

2.3ghz ~1.6-1.65v
2.4ghz~1.7-1.75v
2.5ghz~1.8-1.85v
2.6ghz~1.9-1.95v


I would suggest 2.5ghz and 1.8v...temps never went above 45c for me

Anything less than 2.4ghz on that CPU is of a waste of potential...

Just out of curiosity, what does 2.4ghz equate to in the amd + naming scheme. like 4000+ or sumthing?

You wouldn't happen to drive a turbocharged Mazda RX-7 would you if my engine codes are still correct, although I'm pretty certain they aren't.

i have a 2600 desktop locked that will do 2.3 ghz on 1.85 volts on the same board, but make sure you update to the Rev. 1012-E BIOS, you get Sempron support and the 1009 BIOS has some issues I had to deal with including a locked FSB after overclocking.

yea, you're correct on the model Turbo RX-7, but fc3s is actually the chassis code. The engine code is 13B. Still pretty amazing that someone outside of a car forum can id the rx from the fc3s code.

A buddy of mine was a tuner car freak, he couldn't remember his Social Security ID but he could rattle off every chassis and engine code like it was the alphabet.

2 ghz is a 3000+, 2.2ghz is a 3200+ so I if you follow the 200MHZ bump rule, 2.4ghz would be a 3400+ and 2.6GHZ would be a 3600+, but don't quote me on that.

I think you would need 3GHZ to be rated as a 4000+

AMD 64's need 2.4GHZ to achieve a 4000+ rating on the 939Pin platform, It has a new core architecture and Dual Channel memory.

The same speed (2.4ghz) results in a 3800+ rating when using single channel memory on Socket 754

I was debating on jumping on the A64 band wagon, but its still too much money right now. It took me this long just to reitre my athlon 1200 tbird and my 1400 tbird pc's.

Not realy..

AMD Sempron 3100+ (Socket 754) is 111$ with a factory HSF. It's not a true AMD64, but has most of the performance benefits.

Or the AMD64 2800+ is only 120$ (OEM no HSF) shipped!

Combine that with a 75$ Chaintech Nforce 3-250 Motherboard, Overclock it a bit, and you have a hell of a low budget special that will make most Athlon XP's run and hide!

A NF-7 (78$) and a Mobile 2600+ (95$) or a Mobile 2400+ (87$) will set you back nearly the same as a AMD 64 (165$ vs 195$)

Im waiting for Nforce4 boards w/ Sata II w/ NCQ
