I'm going to be getting a DFI LanParty NFII Ultra-B board in a week or 2, and an Athlon to go with it (Barton Core)... I was thinking of just getting the 3200+ XP, but I'm just wondering from your own experiences & knowledge, which of the Barton chips will OC the most? I'll be pairing it up with some PC3500 RAM (433Mhz), so hopefully that will be ok for the task! Any help would be great cheers, as I'm gona get the shopping soon!
get one of the mobile athlonxps they have at cpucity.co.uk and overclockers.co.uk 1.45v default, bigz has his mobile xp2500 @ 2.7ghz!
It's only stable up to 2620Mhz, but yeah, if I was buying a Barton, I wouldn't look any further, my previous 2 Bartons were stable at 2525 and 2555Mhz. I could run benchmarks much higher though
Will the Mobile Athlon be ok to use then in the DFi board? as it doesn't really say! Or are the chips just multiplier-unlocked for the speed-step type of program? If so, the XP2500-M sounds tempting, but might try a higher-speed chip perhaps & have a go from that, maybe try push the 3ghz barrier... ?? BTW it will be water-cooled, got my own block designed & will be making it up sometime soon! **EDIT** Just read the other post so maybe not go for 3ghz
also, starting with a higher clocked chip doesn't rwally mean you'll get a higher overclock in the end because most of the chips use the same cores anyway whether they run at the same speed or not.
True, I didn't really think of that! So in a way then the 333FSB Athlon-M's are just the same as the 266FSB's, but with the clock increased to get a better speed? Sorry to sound a bit dumb here, but kinda new to athlons & this new machine I'm building is more an experiment than anything!
Not always but a lot of the time, yes. That's why a lot of people have xp2500's that they could just set the fsb straight to 200, because they were basically 3200's.
So the 200FSB should be ok then off the 2500+ XP?? Think I might go and order one of these then, just hope the core-size is the same for the Athlon-M as it is for the regular Barton, or I'll need to re-design the cooler again
My Athlon-M isn't a great clocker in comparison to some of them out there, but I can run 2200Mhz with 1.5v, it just requires a lot of volts above 2500Mhz. The ones that you want are the 133Mhz (266) bus ones, they're rated at 45W. I've got multipliers from 5 to as high as I need, and I'm running fairly low fsb in real terms The Mobile 2800's might clock slightly better than the 2500's because they're starting at a higher Clock speed with the same voltage. I've got this one running under water, it's full load temp is 10-11'C above case temperature. My watercooling isn't ultimately awesome cooling, it's 8mm hose and a low flow pump, with a 120.2 radiator with some quiet papst fans on it. 3Ghz is a hell of a clock though, you'd require some huge luck to get there, the highest I've seen prime stable has been around 2850Mhz.
Either a Pre Week 39 2500+ Multiplier unlocked Barton OR a Barton-M 2500+ What cooling will you be using?
Next Question - does the Athlon-M need anything different, ie, chipset or board wise, or will it be ok for use on the lanparty board? Cooling, I've got a waterblock designed which I'm gona get made up (its in Extreme Cooling forum), and the radiator is 7"x7.5"x2" in size (from my old car), and will have 2x120mm fans in a push-pull on the rad to keep temps down as low as possible! I'm still trying to get hold of a SwifTech MCP600 but with little luck so far but fingers crossed I should have one in a few weeks, month tops! Hopefully that should be ok to cope with the overclocked Athlon!
the mobiles will work fine in that lan party board u said earlier. there isn't really any difference although yours wasn't really recognised in cpu-z was it bigz?
Over-clock UK are getting some new DangerDen pumps that are better than the MCP600 should be here soon Will have to check this block out Got a link??
The only non mobile barton I'd exchange this one for is an AQXEA week 30. My unlocked AQXEA week 31 maxxed out at 2600Mhz (for superpi), and my unlocked AQUCA 0328 maxes out at 2645Mhz (if lucky I can get a couple of superpi runs at this speed). The mobile barton clocks up to 2735Mhz with the same stability as the AQUCA0328. If you want, I'll see what my "max" screenshot is later on, just downloading a few bits and bobs at the moment. Edit: btw, Hi firelord, nice to see you over here
Still working on the design (final measurements n such, but this is what I've got so far. Slightly different design mind, trying to reduce heat-soak (baaad heat-soak) by not having a giant copper-clock! (Link http://forums.bit-tech.net/showthread.php?t=52802 )
Athlon-M 2500+ is 1.45v Athlon-M 2800+ is 1.65v Both run at 266FSB (so 200 like you say should be possible ) Would the 0.2v make much difference to the chip then? and its potential to be overclocked?
go with the 2500+, I can run my 2500+ @ 1.5v 2200Mhz as Ive said. The 2500+ is a propper Mobile chip where as the 2800+ is a desktop replacement mobile chip Lower volts at stock means higher clocks IMO, you could expect for at least 11x217 from that chip with very little voltage.
