Beware: Barton 2500+ New Stepping Multiplier Locked!

[djguju117]

I just pick up a second Barton 2500+ and this time the multiplier was LOCKED. Here's the stepping:

AXDA2500KV4D
Z356137260768
AQYFA 0342UPMW

My other Barton 2500+ is unlocked however the most stable I could get it to run and pass Prime 95 for 2 days straight was at 2.2ghz (11x200) so I was not messing with the multiplier anyway.

Also, on an odd strange note, the locked CPU actually runs cooler than my unlocked one when they are running at the same speed (2.2ghz, 11x200). I'm going to end up keeping the locked CPU since its running about 6 degrees celsius cooler. I guess its a give and take kind of deal, give up unlocked multiplier, got lower temps.

Even with the locked multiplier these chips have been a hot deal. $375 processor for $90 just by switching the FSB in the bios from 166 to 200.

There is a list being compiled here of locked and unlocked steppings:

Good heads up...

Just to make sure though, you are running a nForce 2 chipset, correct?

 

[djguju117]

Yup... NForce 2 Ultra 400 chipset...
Abit NF7-S Rev 2.0

 

[bjc112]

Good heads up then.

Wonder why AMD is going this route...

Reguardless, the 64 is well on it's way.

Anyone know which stepping Newegg is selling? I'm debating whether or not I want to buy one. :\

Looks to be locked..

AQXEA

If you are still feeling uncertain, go for a sure buy @ Excaliber PC or SVC for a guaranteed stepping.

I got one from newegg last week. AQZEA (week 41). It's reported as locked. Had to RMA the mobo for it so I haven't confirmed myself yet. From what everyone's reporting there's high chances for locked cpu if after week 39. Anyway it's crapshoot from newegg, some are locked (after week 39 generally) some aren't (again, generally pre week 39).

I just ordered a 2500 Barton from Newegg on Tuesday...got it yesterday...and it's locked. Stepping AQYFA 0342.

To me it's NO BIG DEAL because I'm just going to play with the FSB anyway. From everything I've read, it should easily do 11x200 with stock cooling. Hey, 2.2GHz and something that performs nearly as well as a P4 3.2 for $90 ain't bad!

I was able to upgrade my whole system (minus monitor, vid card, keyboard/mouse) for $420. This includes a new case, Abit NF7-S, Barton 2500, 512MB PC3200, Seagate 120GB Baracudda drive, and a Norcent/Liteon 52X CDRW. I'm living with my old overclocked GF3 Ti200 for a few more months.

Can you post an HQ :camera: of this Barton, or can you tell us what bridges are cut. Thanks. Peace.

I ordered a retail 2500+ on friday from newegg, and it's unlocked. 12x200 @1.725v so far

 

[x3m]

Yepp.

It seems that Barton 2500+ manufacted after week 40 is locked. Anyone knows how to bypass this? And is it just regarding the 2500+ model?

 

[sukhwinder21]

is this one locked or unlocked ?

Stepping Code: AQZEA: 0341RPMW

$104 including shipping at excaliberpc.. this is $14 more expensive than the ones at newegg, which could be locked or unlocked.

so if this one is unlocked, is it a good deal ?

thanks
