Barton 2500 Stepping and Results

[Stephan]

I just got my Barton 2500 yesterday with the following stepping.

AQXEA 0323TPMW

Anyone ese have this same stepping with good/bad/indifferent results overclocking? Anyone know if this will be a good candidate for O/Cing?

Thanks!!
:beer:

[Jarhead7236]

welcome to the forums...try the search function...or the cpu database linked on the main page...beware of the dubious results, tho....

[Stephan]

Thanks for the Welcome.

I did find the CPU database and a few individuals that had about the same "stepping." It seems as if it is a rather new CPU hence there isn't a great deal of information/stats as of yet. Thanks again.:beer:

[ajrettke]

Yeah I'm interested in these as well. I refuse to look at the database. It honestly ****es me off! Uhh yeah my 1.0 duron did 2.2 with a custom phase change on my PC Chips mobo! (these 1.0 durons really anger me because I had the Wc'ed 1533 and have screenies and 3dmark scores etc and others don't list anything in comments....) Not to mention how many people probably think that as long as it posts it counts and they put it up there....arrr i'll stop ranting

But could people post results with these :D

Whenever I suggest that someone look at the CPU database, I always include this disclaimer:

Ignore obvious typos, lies, fabrications and any liquid nitrogen cooling.

I have that EXACT stepping and date. I will let you know how I do with it later, I have been waiting for my 8rga+ to come back from newegg ( RMA ) and it is getting here today....so time to crank this thing :)

[Stephan]

Great! I'm looking forward to hearing your results!:beer:

I've got a similar one. AQXEA 0323UPAW.
It would do 2400MHz at 1.80V watercooled.
I'm back to using an AQXDA though.

[Andy71600]

ive had amazing results with my AQXEA at standard voltages... i hit 2.3. So good luck with yours !!!

[Gautam]

It looks like a decent stepping. The only area of slight concern is that its third letter following the week is "M." This means that its wafer-quality is mid-level, and you'll probably fall about 100mhz of those that have "A's" at the same voltage. If you have good air-cooling, you can safely expect 2.4ghz.

I've also heard that the lower the 3rd letter the better, but my case seems strange.
Between the two steppings I have tested, the AQXDA 0313MPMW is winning by about 100 MHz and also requires less Vcore to run at the same speeds. Just judging by the stepping the AQXEA 0323UPAW should overclock better, but in my tests that wasn't the case. I find it odd since the AQXDA is 10 weeks older and has a "M"edium wafer quality.

Kinda makes me want to put the AQXEA through it's paces again, since I initially only tested it for two days.

[Gautam]

Your is a strange case... an AQXEA should do better than an AQXDA anyways. Perhaps its the first letter being "U". My UPMW sucks a lot more voltage than most DLT3C's to run at the same speeds. But one can only guess what all those letters mean.

I just got my Barton 2500+, a AQXEA 0324SPCW from newegg, doing some burn in tests and then oc'ing!

[Hedgehogforprez]

Well rather dissapointing news, I can't get over 2310 running 1.85v and no matter how much I rack up the voltage I can't get it stable at 2365 :( I guess some burn in's will be in order....maybe when I get everything else in for my second system I will be looking at either an AQXDA or DLT3C 1700......

[Mustanley]

Is that using the SLK-900u? I would've expected better from that cpu. I hope it doesn't stay stuck at that overclock.

[Hedgehogforprez]

Yup using my 900u on this thing. I am burning it in at 11.5x200 right now and after about 48 hours of this I will be using the sandra burn in wizard for another 24 and see how high I can get then.

[qwerty57]

your guys got the retail's from newegg correct???? that was a mistake If your into oc'ing

[Namagomi]

Retail is 3 dollars more, comes with a heatsink, and you get a 3 year warranty. That's why I got it, anyway.

[Hedgehogforprez]

Well I got mine retail from googlegear, only got it because I was building a system for my manager and I ordered the 2500+ and she said she wanted something faster, so I offered her a trade for my 2400+ she said deal and here I lay with a 2500+ that can't get above 2.3 stable :( Burning it in should help though, hopefully.

[]-[itman]

Getting retail is really pointless because the heatsink is useless and as soon as you add AS, it voids the warrenty :|

[Stephan]

That's an interesting comment concerning the 3rd letter in the stepping having something to do with wafer quality. Is there any proof that supports that or is it just pure speculation?

[qwerty57]

I dont know Ive seem MPMW's out do TPAW's so if the "A" in the second one was better it would OC better. its a mix of the entire chip, lol.. 90% luck IMO...

[Josebmw]

How well does the AQXEA 0324SPCW do, these retail bartons are not bad, they can reach 2400 Mhz, without extreme voltages, im doing some burn in for a while then some oc'ing....

The "A" is the Production batch of the week it was made on, I have a "C" from week 24, does anyone have retail barton oc's?

Then what would a aqxda 0315spD w mean?

[Josebmw]

I dont think it means wafer quality, the "O" is the batch number. I have a 0324SPCW, so my batch was "C", the third made for 0324.

[Col_Loki]

Hey guys while were on the subject of letters n dat, i thought that ....

AQUCA = 333 FSB ,
AQXCA = 400 FSB.

Ie the 3rd letter states the FSB, this is a little mad if your getting the X on 2500's. Thats just something i red somewhere, will try to find the site.

[Josebmw]

AXDA2500DKV4D tells the processor frequency, fsb, core revision and speed rating. The stepping "AQUCA""AQXCA" have nothing to do with the fsb.

[Col_Loki]

Ok fair enuf, got a pretty good guide from Here (http://www.hardcoreware.net/forum/showthread.php?t=8304) . Seemed like a very well versed guide & here is where i was quoteing from!!

This is BS. Most even pre-3200+ Bartons were AQX_A. Only the earliest were U's. Now there are JIXHB T-Bred B's with only 266mhz front side buses. Don't have a clue as to what it means, but it certainly is not indicative of the front side bus.

The later batches are progressively closer to the center of the wafer, and thus are of higher integrity.

[Col_Loki]

Hey Gautam, you put it soo sweetly This is BS
In fairness , have just posted where i got the info and since you seem to have no idea what that letter stands for why are you rippin the ****??

Bit insulting, granted i did say my info was seems to be wrong given that that it was showing up on Xp2500's.

[Josebmw]

So Gautam, my "C" batch is worse than let's say a "K", in overclocking ability?
