250fsb on barton possible

[Xplos!ve]

is it possible for 250fsb on a locked desktop barton (not mobile) at 2500 stock?? my m8 reckons he done 250fsb 1.85 250*11 =2750 mhz somehow i dnt belive him, bartons cant even handle 250fsb??

*EDIT* opps i was thinking bartons were quad pumped :/ just realised but still can they handle 250fsb double pumped, probs can coz i was thinking of them being quad pumped

I wouldn't put it completely out of the question A good NF7 or DFI lanparty could pull off 250 without too much trouble. The latest Bartons do seem to be capable of speeds above 2.6GHz. Even the non-mobiles. If he's got nice cooling, a good power supply and a good motherboard, I'd say that could be possible.

Btw, post stuff like this in the AMD CPU's section next time. It's a question directly related to them.

FSB can go as high as the ram and motherboard can handle on a unlocked chip on the other hand i really doubt your mate hit that speed with only 1.85V most mobile bartons need 1.9V+ to hit that

 

[Sentential]

Its possible alright. I had 257.7 on mine

lol, this made me think of the scene in Back to the Future III when the Doc and Marty are asking the train guy how fast he reckons it could get up to - lol - I would have to agree with what they all said - it could be possible if u have a good mobo, good ram, and a good cooling setup - I would say 100:1 that would not include Air, lol

ok cheers guys i posted here because im used to pentium4 fsb settings and thought the amds were also quad pumped thats why i thought it was a bit dodgy, but how comes ppl with mobiles run high multipliers and 200fsb?? wen they cud still run the same speed but with a lower multi and higer fsb and sum ppl even have the ram, cooling and mobo etc to achive it thats why i also thought it was a bit wierd coz ive never seen anyone in tehre sig or anything wid that speed

thx guys

AMD's tend to act weirdly sometimes once you get the FSB too high. Example, I could do up to 2.6GHz with the FSB at 228, but to get 2.7GHz, the best I could do was 210. Just a guess, but maybe thats why. Also getting memory to run at high speeds can be difficult quite often.

My locked barton won't go past 210fsb (NF7-S), and its not the RAM because I pushed that up to 240fsb in my friends motherboard. I think that most of these guys forgot the "locked" part of your post

 

[Gautam]

I didn't. He'd need some beefy cooling though. But 2.7ghz is not unheard of on the newer Bartons.

 

[enduro]

I think BilloBobO is right, the highest fsb I've ever seen on a 2500 that was locked was a 220 fsb and he was at 2V all ready. I don't think that it is possible. With a mobile or an unlocked desktop yeah, it's possible, but not a locked desktop.

 

[Gautam]

I believe that the only reason you don't see them is because no one bothers to buy locked bartons anymore. There's no reason why they wouldn't clock nearly as well as the mobiles. The process is very mature now and you won't find that much variation. The desktop AXP's are great overclockers in their own right, but no one bothers to buy them any more.

Hi, since we are on the topic of mobo's, I thought I'd ask which one of these will allow for the highest multiplier and fsb?

ABIT AN7 (nForce2 Ultra 400)
DFI nForce2 Ultra 400 NFII Ultra Infinity
Abit NF7-S Rev.2
shuttle AN35N-Ultra

I hear that some of these have the multiplier locked at no higher than 12.5 and can't handle high fsb.

I'm planning to get a mobo for the 2500xp-m and OC. SO which board and why?

Thanks

Infinity. 3.3vdimm. Infinity allows for all multipliers to work.

NF7 can/can't handle high fsb's. The DFI would probably get the best rating for out-of-the-box overclocking without mods. The newer NF7's are looking more promising though.

Beware of DFI's boards having mysterious bios problems. Some are solid as a rock, but others run into various problems.

 

[Gautam]

Don't count out the AN7's either. I know everyone hates them, but they do get past 240-250 pretty consistently with the right BIOS. Also give up to 3.2vdimm right in the BIOS.

i sir. ive had mine to 247...it wasnt even close to being stable (temps maybe?..doubt it) but it did do 247.

The reason that the desktops won't overclock as well, is one (dependent on chip) the mult. is usually locked at an undesireable value, two, mobiles have more head room on their voltage levels ( starting at 1.45V ). Other than that, I agree, since mobiles and desktops are about the same except in a bridge being cut, they should overclock the same. who knows.

Nerm over at overclockersclub has hit 2.7 on air when his water cooling gets in he is ganna go for 3.0

im at 2.4 right now and can probably go to 2.7 as well

both are super locked desktop chips

Thanks for the info. It doesn't surprise me at all that the desktops do as well as the mobiles.

Can you list the voltages needed to get that high and which chip you guys have. If it is a 3200+ or 2600+, either way I'm impressed and corrected.

 

[Agallion]

i think Nerm is at 1.825

im currently at 1.85 but im just keeping it there so i can get the max overclock, im not going anyhigher until m watercooling gets here( Dtek is currently out of stock of my res)
