Building an XP-Mobile rig, go with the XP2400 or spring for the XP2600?

I plan on building a little cheap Athlon Mobile BF1942 rig, specs:

XP2400-M
Shuttle AN50 Nforce 2 Ultra Board
Thermalright SK700
Cheap PC3200 1GB KIT
Enlight 420W PSU
Maxtop Midtower chassis
Radeon 9800 PRO 128MB


Will most XP2400-M's do 2.4-2.5GHZ? I really want at mininum 2.4GHZ. I was looking at Hardcorecooling.com's 1GB PC3200 DC KIT, its pretty cheap, will this suffice for hitting my goal? My other option include kingston valueram from hotdeals, or even Kingmax PC3500 for $94 per stick ( I want 1GB). BTW I haven't read any reviews about the shuttle board, but I've owned two AK31A's and had great expierences with them, will the AN50 provide all the bios tweaks I need to hit my goal?



Thanx!

most 2400's will make 2.4 but usually need more voltage on average compared to 2600s to do it. but its really a crap shoot the best mobile I saw was a 2400 but I've seen more 2.5-2.6 at low volts from 2600s. I would call my chip average. takes 1.7V to do 2.4 1.85V for 2.5 2V for 2.6 and 2.1V for 2.7. I normally run at 2.6 but thats only because I have water. I was at 2.45 at 1.8V before my water got in.

so far... i've only tried 2

a 2500+ and a 2600+

both were able to 2.6 ghz

2500+ required 1.85 volts
2600+ required 1.95 volts


it's all hit or miss...

i'd say just go for the 2500+

also i believe it's a shuttle an35 not an50 (that's for A64)

if i were you, i'd get an nf7-s ro ultra infinity (dfi)

i am currently running a fsb of 247 on this infinity

it's nice stuff

I agree on the NF7-S great board on the cheap. also consider a slk947 from www.svc.com same price as the slk700 and a better hsf. just requires a board with 4 bolt holes around the socket. which I know the Nf7 has and tyhe DFI board have but I only had a AN35 for a week or so and I honestly don't remember if it had holes or not

When I was researching the mobiles before putting my new system together, the general impression I got was that the 2400 topped out around 2.4-2.5ghz while the 2500 and 2600 both topped out around 2.6 and 2.7ghz. I went with a 2500+ from Newegg, stepping IQHYA, and it can do 2.6ghz Prime stable with 1.8v. Nothing's a given, but I do believe that your chances for a 2.6ghz oc improve once you step up to the 2500 and 2600.

If you want a guaranteed 2.4GHz, I'd spring for a 2500+ or 2600+. The 2400's get up in that range for sure, but it's not as likely.

Its listed as $29.99, is there a coupon code I must enter during check out?


BTW the SK700 is only $13.99 at hardcorecooling.com.

Two Mobiles here:

2600+ 1.75 Vcore for 2500 MHz 166/166 x15
2400+ 1.95 Vcore for 2400 MHz 200/200 x12

I think that the higher Vcore on the 2400+ has more to do with the 200 MHz FSB than the chip being significantly different than the 2600+.

I run my 2600+ @ 2.4ghz (200x12) @ 1.7 volts on A7N8X-E 'lux

I haven't tried any higher as that's fast enough for me.

*votes for 2600+*

actually, I don't think it takes much voltage to get 200FSB...it's getting the clock speed that takes voltage.

My 2400+ runs at 200*11=2200MHz at 1.65 volts...
but 200*11.5 takes 1.75 volts, and 210*11.5 I haven't gotten stable yet since I'm too chicken to go above 1.8 V (which drops to 1.76 V under load)

Actually, I had to get an upgraded POWER SUPPLY to be able to run at 200FSB. It was strange... with the 300wattPS I could NOT run at 200FSB at ANY CPU SPEED.
With the 450w PS I could.

So I am a firm believer the Voltage supply is vital to FSB setting too...

Though that may have been something to do with the MOBO Chipset too... Not sure. The world may never know. :)

yeah, my old Antec 350W works all right, but I've got a 9800 pro, tons of fans, the mobile with a gig of RAM, a Raptor and another hard drive...sometimes I wonder if overclocking it with high Vcore is asking too much.
