Hello, picked up this Barton from Tysonator in the MM a few weeks ago but only got around to installing it the past few days. I have several socket A CPU's at the moment (for some reason?) and have been testing them all out.

I have two chips that were manufactured in mid 2003 and they are of course unlocked however the XP3000+ cpu pictured above also seems to be unlocked and I am able to adjust the multipliers upwards or downwards with no problems so far?

AQXJA 0503VPZQ

I thought all the socket A chips were multi-locked sometime late 2003?

Any Old-School socket A geeks care know anything about this please? :)
 
Had an 04 Week 10 that was unlocked downwards, theres a few post week 43 (or was it 46? can't remember) 03 bartons that are unlocked, rare as hens teeth though.

I had an unlocked 2800+ Barton however, it finally caved in a couple of weeks back after over 4 years of service. Could never really push it past 3200+ speeds without problems though so suppose it wasn't doing that much good :p

EDIT:

It was a week 40 in 2003. Oh well I guess it can make a nice keyring.

I believe all the Barton cores were unlocked.
Probably one of the most overclockable chips in history that i know of.

Think i got 2.9ghz out of the 2500 1.8ghz chip.

Absolutely loved it, so easy aswell compared to the modern chips.

EDIT: Also even if its not a barton it may have been unlocked anyway as the 3000/3200xp were tp of the range so there was no need to limit them compared to the other chips
 
All bartons were certainly not unlocked, AMD started locking them after a certain week in 2003, googling a bit has turned up: week 43 to 46 are all locked and there are rare cases of post week 46 being unlocked, one of which big wayne seems to have.
 
Ok thanks for replies, guess it's just a bugged Barton that made it through the system?

Anyway I changed the multi upwards from 10.5 (XP3000+) to 11 (XP3200+) and it passed testing no problem.

That's sweet! I never had a socket A chip that would run 2200MHz using just 1.625vCore, my original XP2500+ Barton (circa 2003) needed 1.775vCore to run at this same speed.

Now I suppose that socket A chips can run a lot faster, what is a good speed to aim for and what is the safe vCore to use?

In the mean time I will just plod on adjusting the multi upwards and see where I get? Currenty running Small FFts on this:

No one seems to have mentioned that the reason that chip is unlocked is because it must have come from the same batch as the Mobile Barton's.

They were the last socket A chips in production and came unlocked with lower default vcores, 1.35-1.45, so were great for over-clocking. Even the later Sempron socket A chips went back to older thoroughbred B cores I think with 256K cache, so those are the best socket A chips around.

That bios looks like an Abit NF7 - had one of those running a mobile Barton myself. Great combo and nice pics. :)

1.75v is a good starting limit for "average" cooling. 1.85 for good air, 1.95 for water/v good air. 2.0 for good water and anything as high as 2.2v for phase or extreme water.

i havent personally heard of a single socket A chip killed from volts that was well cooled (eg sub 60c) - from Thunderbirds thru to mobile bartons.

and i have seen axia's @ 2.5v for 3 years. xp2100 t-bred b @ 2.1v on air for years (still works to this day) barton @ 2.0v for years (still running [email protected] to this day)
 
I had a buggy 2500 that was multi-unlocked. Well, I'm not sure if it was or not, but the jumpers on my motherboard allowed me to run it perfectly as a 3200.
 
I got myself a 2500+ mobile Barton off MM for a tenner, can't wait for it to arrive and see what I can do with it. Currently have the non mobile version, but with a locked multimplier and RAM that doesn't like running at higher speeds so I'm limited to 3200+. Air cooling wise I'm pretty well set, with an Antec 900 with 2 extra yate loons.

i thought everybody and his dog had an xp2500 @ 200x11 on stock volts (1.65v i think)? :p

Happy days indeed.

In the end it was my pushing that XP2500 to around 2.4ghz that killed my wonderful old Epox Nforce 2 Mobo. The CPU still worked fine and continued doing so until I flogged it on auction a year or two later, and made most of my money back. :D

Ok thanks for all the helpful replies!

Here is my Uber-Retro Socket A Testbed! :o

I have just upped the multi on the XP3000+ followed by several hours Prime Small FFTs followed by another several hours Prime Blend.

XP3000+ (2100MHz) Pass Both tests using 1.5vCore
XP3000+ (2200MHz) Pass Both tests using 1.625vCore
XP3000+ (2300MHz) Testing using 1.65vCore (passed Small FFTs and currently Blend testing).

I have no idea why I am playing around with socket A, this stuff is like five years old! :D
