Socket A Barton (Year 2005) Unlocked?

[Big.Wayne]

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?

AXDA3000DKV4E
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?

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:

1.75v is a good starting limit for "average" cooling. 1.85 for good air, 1.95 for water/v good air.

Ok thanks for all the helpful replies!

Here is my Uber-Retro Socket A Testbed!

ABIT NF7 v2.0
THERMALRIGHT SLK-800U
SHARKOON 80mm Blue LED Silent Eagle 2000
THERMALRIGHT NB1-C
CORSAIR 2GB TWINX PC3200 Platinum
SAPPHIRE Radeon 9800Pro with Accelero S2
COOLERMASTER Elite 330 Midi Tower
CORSAIR VX450 PSU

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!

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

Apparently not!

I just dug up this photo I took of my BIOS settings back in the day. . .

I have a AGP Gainwood 6800GT for socket A if you are interested !

Blatent Pimpage!

Off to the members market with ye!

That [was] my XP3000+ Big Wayne is maxing out !

Ah the original owner, yes its a nice Socket A chip, best I personally used!

What speed did you run it at then? stock 2100MHz or?

It runs the stock speed for me using 1.5v which is decent but it doesn't seem 24/7 stable much over 2200MHz so far? still got a little adjusting to do yet but I'm happy with XP3200 speeds at lowing volts.

[edit] Will get your old motherboard installed soon dude . . . btw it's an ASUS A7N8X Deluxe not an A7N8X-E Deluxe, not a biggy but my spider senses saved me at the last moment before I flashed the board with the wrong BIOS!

Happy days.............i remember them well.

I'm just looking at your screenie, the memory is running at 250MHz 2-2-2-11!

Was that BH5 with max volts?

Your 'retro' pc beats my gaming pc

Really? what's your main gaming PC then?

What GPU?

spent all my money on my holiday

Sounds like a good plan!

Is the XP3000+ I am testing a Mobile version?

I don't think so but that may explain why its unlocked? I never seen an XP-M before for not sure what to look for?

Is there something in the stepping code that denotes its a Mobile?

 

[Big.Wayne]

Ah I see, the chip I am testing defaults to 1.625vCore in the BIOS. All the other chips (locked and unlocked) all default to 1.65vCore.

All the Barton cores processors I have atm (XP2500+ XP2600+ XP3000+) run stock speeds totally stable with 1.5vCore. The XP2500+ (aug 2003) can actually run stock speeds with 1.4vCore. Had it passing Prime Small FFTs even at 1.35vCore but everynow and then when I booted the PC it wouldn't post properly and force you to enter BIOS, obviously the chip needs a certain amount of juice to actually wake up! Nudging it up to 1.4vCore got rid of that issue.

Not having a ton of joy with this XP3000 though? It passes 12 hours of Prime Small FFTs at 23000MHz and 2400MHz so far but Prime Blend falls over after about five hours?

Highlight of this chip so far is running rock solid stable XP3000+ speeds (10.5x200 - 2100MHz) with 1.5vCore and XP3200+ speeds (11x200 - 2200MHz) with 1.65vCore.

Am I missing something here? Why would Prime pass Small FFts for days but Fail Prime Blend?

The Processor architecture code for an XP mobile chip is AXM

Thanks!
