First of all, I hope that someone official will shed some light on barton steppings (please )

got 2500+ AQXEA 0329 XPMW

using dr. thermal TI-V7725L 4500rpm aluminium heatsink with copper slug

10.5x200 1.675vcore load:44
11x200 1.775vcore load: 51

No 'oc using stock voltage' success like you see... It's a shock to me when I see people going 11x200 with 1.65vcore
Did you people stress your system long enough? Mine worked ok 11x200 1.725vcore but got frozen while folding, 1.75 started folding ok but made errors after 4-5 hours, 1.775 looks ok

what mobo, RAM and PSU do you have?

whoa that can't be right
stock voltage, frequency, and it's going to 60C? the sensor must be getting wrong readings (upgrade BIOS) or you mounted the heatsink incorrectly (or splattered the thermal paste all over the place)

Yah have thought of wrong readings, but I don't like to OC if the readings should be right.
Gave it a Delta Exterme Screamer and got a high at 52c, and that makes sense.

But I would really like to know if it's socket or diode-readings when temps are posted.

I get socket readings at 41c when my diode reads 55.

Come on guys, get some real cooling! An SK-7 + Smartfan II @ 2600RPM will work wonders.

oh, I missed that that's your custom diode reading the temps
just stick with the socket one, it looks more realistic

I just replied to another thread, I've so far (new system) overclocked my 2500 from 11 x 166 @ 1.65 to 12 x 166 @ 1.65 and it's been working fine.
Just watched the simpsons and it's been stable, will try some benchies then go up to 12.5 etc.

UDHA, the most important info is your stepping and cooler
my guess is AQXEA, that's roughly my o/c

in what order were the steppings for barton released?
AQUCA - AQXDA - AQXEA - AQXFA is my guess
do they get changed after few weeks and never reappear again(get replaced with newer steppings)?

I think it goes something like this, though I bet I'm missing a few...

AIUAA -> AQUCA -> AQXCA -> AQXDA -> AQXEA -> AQZEA -> AQZFA


In terms of OCability, supposedly the scale is:

AQZFA > AQZEA > AQXEA == AQXDA > AQXCA > AQUCA > AIUAA


I'm sure AMD will tell us the actual order... hey, I can dream, can't I?

DEC Pentium X2 5200+ w/ HyperCache (Ezra core)
Asus M7NCD-MAX3 (OPTi Vendetta 82C760)
6x Generic 32MB PC2700 RDRAM (50ns SIMMs)
2x nVidia Millennium X1800 Duo (SLI mode)

"Oh, you started a Rube Goldberg machine. A Rube Goldberg machine... called JUSTICE." <a href='http://www.boomspeed.com/old_camper/amdforumsircchat.ht

oc-ability isn't entirely related to the corecode(i.e. AQXEA), but also the stepping(i.e. MPMW) that determines the oc-ability. I have 2 different 2500+ processers, with AQXEA and AQFZA core, and they are quite equal when it comes to overclocking. Ill list the results:
AQXEA 0332 TPMW
max @ 1.65v: 2150Mhz
max @ 1.75v: 2240Mhz
max @ 1.85v: 2300Mhz

AQFZA 0335 TPMW
max @ 1.65v: 2200Mhz
max @ 1.75v: 2288Mhz
max @ 1.85v: 2340Mhz

It's been said that the XPMW and MPMW steppings are the best overclockable.The TPMW
stepping like mine are moderate overclockers.

Edit:
I'm a member of a Dutch overclocking site, and this is their conclusion on overclockability (list is not complete and results may vary):

Cores:

AQUCA
AQXCA
AQXDA
AQXEA
AQZEA

Steppings:

XPMW
XPAW
TPAW
MPMW
TLPW
TPNW
TPMW
TPCW
WPMW
VPMW
UPAW
UPCW
SPAW

On top are the best overclockers, on the bottom the worst.

DFI Lanparty NF4 Ultra-D
2x 1GB G.Skill PC4000
XFX GeForce 7900GT

Thermaltake Xaser III case

Add an SPMW to the bottom of that list. My SPMW sucks.
