Trying to get my 2500+ to overclock, not sure as to what voltages I should run at. Im sure there is more to it then just bumping the fsb. I got the nf7-s (rev 2.0) and for now I am using 512 xms 3700pt ram. Not for long of course, once the rest of my parts come then I will use my 1024twinX pro

As for now, what do i need to do?

the default is 1.65v, most people can get 2.2 (11x200) at the default voltage. I try to keep my cpu below 2v. but thats just me... some people have no problem running at 2.1+.

ok I am at 2v right now. im at 200x11.5 getting 2.31ghz... Lets see what else I can do hehe... As for the timing of the ram what should I have it at 3/3 4/4 etc?
Anyone know where I can get that 3dmarkpro at (maybe free)

2v is huge, what kinda cooling you have on it, unless u have really high end air cooling or water cooling, 2v is quite dangerous!

If you really wana OC well, get urself a Mobile 2500+, they run @ 1.4v default voltage..... and have the multiplier unlocked!

I agree, you need to keep a eye on your temps, normally anything over 1.85v will get to hot with air cooling. I try to keep my temps under 50c using MBM, the core will be alot hotter that that reading.

He has to have a unlocked Barton 2500 as he said he is at 11.5x200 (Barton 2500 is 11x166 stock)

do those mobile's at newegg for 90$ o/c? We have the same board I just wanna make sure before i order it

Yes the newegg mobiles overclock very well. as for ram timings generaly the goal is as low as you can get them. some people see better benchmarks when runing at 11-2-2-2 i have my fastest times ruing at 6-3-3-2 (the fastest my meory will run).

I will be getting a mobile 2500+ soon and overclocking it for someone, so I will let you guys know what I get out of it

Well mine is cranking along at 2.4ghz. i think i can get more out of it but i need to lap my heatsink and upgrade my psu becaues my 12v line is super low when i run over 2.4ghz.

A good XP-M should go to around 2500-2700 MHz on air (Highest I've seen). My locked 2500 Barton will do 11x220 at 1.85 volts and will stay in the low 40's max load........but I'm water cooled............I'm planning on getting a XP-M here pretty soon also (if the cash thing works out).......I have a friend that hit 2700 with his XP-M on water so I know it can be done............. :D

Why all people is buying a 2500?, a 3200 will overclock better or it won´t?

Bio-Hazard · Post by **Bio-Hazard** » Thu May 20, 2004 5:46 pm

It's all a matter of the almighty dollar...........the 2500's are alot cheaper...........and run just as fast, if not faster..........

No. There are two things going on. One we are talking about the 2500+ Mobile which runs at a much lower voltage and tops out at 3ghz. Most people can get 2.7 on air and some good chips as high as 2.8 on air. to go higher people have used phasechangeing equipment to get up to 3ghz. Second the 2500+ and the 3200+ are the same chip. The 3200+ just tested for higher frequency at the amd plant. That means that at its frequency of 2.2ghz it was more stable (theoreticly) than a 2500+ core. However all Barton chips have the same basic properties and top out at the same basic frequencys. Most barton chips have a top end of 2.6ghz, except for the mobiles. The mobile chips are the cream of the crop from amd thats why they can run 1.45v rather than 1.65v at the same speed.

My Newegg 2500 mobile runs smooth at 12.5 X 200 for 2500MHz at 1.83 Vcore. AN7/SP97 mobo/cooling.

Also 13 X 205 = 2671MHz CPU @ 1.93 Vcore, but I'm not crazy about that much Vcore.

Hmm, ok, clearer now

had to edit, got my 2500+ mobile today.... currently at 1.8v 2.5ghz 400fsb... nice... Oh yeah, amd heat sink and fan lol

Its weird since I have in the pc a 2500 mobile, and laying on the desk I have a 3200+ and a 2500+ barton...

Ebay the suckers. get the $$ and buy a new grahpics card or a new hd.

You'll definitly want to get a new HSF for that baby if you're going to do any serious overclocking.

It's a shame that with my current water rig plus a normal 2500+, the max. I can get out of it is 218x11.5 @1.95V
