Anyone have this? How far have you pushed it. I am planning to install this tomorrow and am looking for some insight B4 I do.

Thanks.
 
I'm still tweaking mine but 2.4 looks good. At 2.5 I have to push the Vore close to 2.0. Everything would work expect P95.

I received mine on Friday.
 
ddawson,

Damn I would have thought 2.5 should be easy on water. What stepping is your 2500+? I've been thinking of getting some water cooling to get to may be around 2.5-2.6. Is that unrealistic expectations?
 
I just got a Barton that week, too. It has the new chip design that is very hard to mod. It seems to be multiplier locked, too. My Asus A7N8X-X can't POST with anything but Auto multi. This is a new MB, though, so it might be to blame.
 
Highest stable settings I achieved with AQXEA 2500+ were 210 X 11 and 215 X 10.5. Some have reported 2.5GHz on air.

I replaced mine with a DLT3C 1700+.

Got my AQXEA 0330 VPMW about two weeks ago. Right now it's at 2250 @ 1.65v. It's been running prime for 2-days with no problems. I did have it up to 2333, but had to increase the voltage to 1.75.

Good luck.
 
Hi !
I get a 2500+ AQXEA and it works 100% stable at 2415MHz with 1.88 VCore. Temp full load is 46°C with Seti@home.

Thanks for the Replies.

Still tweaking, but so far the results have been good.

When I first installed it with stock settings and 768 Megs of PC2700 ans 11 x 166 I was at 1.83GHZ and I got a score of 13256 with 3Dmark2003 SE.

Now with current settings of 12.5 x 176fsb I am at 2.2GHZ and a score of 15652. This is with ram at most aggressive settings with the exception of SDRAM 1T, I had to disable that. Unstable with it on. No voltage increases and all air cooled with the following temps. 42c idle, 48c under load, 32c case temp, and room temp is appx. 25c. Nice little free performance increase I'd say.
 
I was testing all night last night.

My FSB hits a wall at 215 with 2-2-2-11.

My CPU with V1.65 hits a wall around 2.2. I need V1.85 to keep 2.3 stable for 8 hours. I'm not quite comfortable with it but at V2.0 its stable at 2.4 for 8 hours. The load temp at 2.0 was 43-45C on the Abit with a room amp of 26C.

It may not need to be that high as I got tired and decided to see what would happen.

It looks like the 330 likes high vcore. Temps doesn't seem to be the limiting factor unless you pump up the volts.

I either got a poor CPU or AMD just has trouble hitting 2.4-2.5 with reasonable voltage.

Almost forgot, aqxea 0330vpaw
 
Wow VPAW. According to a popular theory the A should stand for the highest wafer quality, and yet no spectacular OC results. May be that theory is bogus after all?
 
According to my theory the A is linked to voltage required to run at default. Those letters higher up alphabet such as M require less voltage at default.
 
Just an update.

Sweet spot 11@215 at V1.85 = 2370

I can hit 2400 but it takes 1.95 to be P95 stable.

2500 takes 2.0 and that still wasn't 100% stable.

Current temp is 46 Load, 30 AMP, and the water reads 38.
 
I've got a pair of these I've been working on in my AMD duallie.

Running together, they need 1.40 Vcore to be stable at 2000 MHz, 1.45 Vcore to be stable at 2070 MHz, 1.475 Vcore to be stable at 2100 MHz, 1.55 Vcore to be stable at 2160 MHz, and 1.675 Vcore to be stable at 2250 MHz. That last one is a big jump in Vcore and temps. I'll probably just run 2160 MHz and 1.55 Vcore. Duallies heat up a lot more than single-CPU machines, since there are two heat-producing chips in one case. Right now, I'm looking at temps of 55-60C with dual SLK-800's and Panaflo H1A fans at full speed.

I've tested three Barton 2500's... one 0329 and two 0330's...

The best one is my current one, an 0330 VPMW. It does ~ 2455 MHz Prime stable (24 hours tested) at 1.95 Vcore. At 2.0 Vcore, 2500 MHz, Prime bombed out at 1.5 hours :( and I don't dare go higher on the voltage.
 
Cool , I feel better and better about my chip. Barton 2500+ AQXDA 0313MPMW @2500MHz (208x12) 1.825 vcore. I just switched from normal water cooled to chilled water (8C water) and can run the same speed at 1.80 vcore. Still testing so that number may drop further.
Load temps measured from internal cpu diode before were 38C and after switching to chilled water it maxes at 24C.
I've got another Barton 2500+ AQXEA 0323VPAW that was doing 2200MHz @1.70Vcore (on air), but I have yet to test it under H20 cooling.
