Overclocking Results: Super-PI Challenge! (please read the first post)

the comparison is between a regular XP Barton 2500+ and a Mobile XP Barton 2500+

 

But an xp2500+, xp2800+, xp3000+, xp3200+ xp2500+M all with barton cores could conceivably come from the same wafer. (OK its unlikey afaik that there would be such a wide spectrum of specifations coming from the same wafer but it could happen). What each die is capable of at stock speeds does not matter, they are all of the same technology.

 

but they all have different multipliers...


a mobile vs non-mobile comparison i believe

XP2400+, XP2500+, XP2600+ (i've yet to find one higher or lower)

-M 266MHz FSB 1.45V

reg 333MHz 1.65V


same .13micron, same 128/512 caches, but obviously they feature different multis & settings.... its like saying a XP2200+ and a XP2500+ are the same because they're both 1.8GHz at stock.... (ok bad comparison, 1.8 vs 1.83)

its meant for a different application...

 

I understand your point of view about multipliers and FSB but this not about comparing stock CPUs, Its about how fast you can get a CPU to calculate pi. IMO there really shouldnt be a clasification between AMD and INTEL but you will never stop clasification. It makes people feel better about their results, which is fine in itself but at the end of the day its about ultimate processing power and CPU core is only one of a massive ammount of variables involved.

I dont think your comparrison of xp2200 and xp2500 is fair, not because of clock speed but core design.

Yes the mobile CPUs do have a different purpose but thats after they have been made. There is no thought process, afaik, of the manufacturer that they will produce a batch of 2500Ms they produce a batch of Bartons and then its decided how each die will be clasified, so in essence they are identicle. They just have different properties due to their postioning on the wafer or other factors too complicated for my comprehention.

 

fivecheebs are you a intel man?

 

sorry this is going slightly off topic lads

EH? no! why'd you say that? All im saying is a barton is a barton is a barton. no matter how its been labled.

edit: soz i just realised why you thought i was intel. It was the remark about not catagorising wasnt it. oopseh!

 

sory, any way.

ill post my times as soon as i get my ram and lend it to murdoc to see what times we can get.

 

So if someone had a good stepping 2500+ barton cpu thats stock voltage was 1.65 and FSB was 166 but had such a good core that it could run 1.8ghz at 133fsb and 1.45v should that be classed as a mobile?

I dont know what your argument is anymore, surely you can see that a Tbred XP2400 and XP2700 are exactly the same thing just one runs different mult/fsb at stock... whats the difference with anything else?

 

Managed to break a minute, still waiting to order a mobile 2500, should get some good times with that

Tbird 1.2Ghz

Motherboard is unknown, this is origianlly an HP system i bought right before i entered college (3 years ago) and for the life of me i cant get any info just that it's running on a VIA KT133A chipset

Stock Air cooling

PC133 3-3-3-6

I have 2 other comps atm and i'll run the same on them in a bit. On a side note i went from a 168 second score to 126 from a reformat and from Windows ME --> XP Pro i can't believe how great reformats are even though they can be a hassle.

Edit: just realized 2min 6 sec doesnt equal 206 so my score isnt as bad as i first thought!

 

Could well be to do with running 100 fsb as opposed to 133 (as some of the later chips did iirc) Also sd-ram will hamper memory bandwidth considerably.

 

Ordered a prescott when i meant to order a northwood-c: Will be getting a c for my sister, if it performs better I keep it.


STILL @ STOCK VOLTS. But slightly unstable. Currently been stress testing (prime 95) for 3 hours @ 225x14 (3.15GHz) - still havn't increased volts. Abit IS7-E mobo ("street racer" performance accelerator), 1 gig OCZ EL DC RAM (running 2-3-2-6 @2.8V (stock) 5:4 divider). Locked PCI bus (33MHz).

[edit] Aero4 cooler with too much AS5, that temp on screen is just after boot, idle's around 55, tops out at 70. If I loosen the timings on my RAM it just gets more unstable :\ so I've elected to run with a lower speed. [/edit]

And lastly the last comp i have around me!

AMD Duron 750 FSB100

Motherboard: Compaq 06E 4h

PC 133 3-2-2-5

Stock Air

I thought that perhaps these 3 low end comps might be interesting as data points so i hope you humor me a bit

 

I think this is higher then some mobile Xp's

On Air my XP2400 thorton w/ 512k cache

2.7Ghz!!!



The overclocking gods must have been with me the day i brought this chip

one very happy 'doc

 

that chip goes further and further every day...

 

his obsession with super PI is also becoming quite distrubing

And who recommend you take the multipier up? Thankyou Thankyou

 

/me was aware what the Multiplyer did

'doc

EDIT: get yo ass on msn fo-shizzle!

 

Very nice clock speed there! Especially on air cooling. My 2700+ has gone to 2594mhz on air cooling, can probably get a bit more out of it. I think its because the thermal goop is knackered

 

Ive resisted from posting this humilitating time, but i want to do a before/after time, chop 2 mins off. maybe

EDIT: guess i gota post the specs
