I ordered it Monday when the price was $181. I took my chances and this is what I got. They never told me what I was getting, I found out when I opened the box today when it arrived. :)Quote:

I seriously thought that the very early cabne week 30's would be the only ones that clocked as well as they did. Now that more and more steppings are doing super, it just seems that amd has stepped up their quality all of a sudden. On some of the other threads, it seems that even the san diego's seem to be doing much better lately.
Way to go AMD...Keep it up! Givin' the broke man a chance at an FX 59!
Looks like I have pretty much found the max of this chip. 11x260 2.85ghz 24+hr prime stable 1.3x113% vcore, 11x267 2.93ghz 32m pi stable 1.425x113% vcore, 11x278 3.05ghz 1m pi stable 1.425x113% vcore. Best suicide shot 11x282 in avatar, same vcore. Went as high as 1.35x123%, couldn't get any higher. This chip runs hotter than my 3500, even with less voltage, but I haven't taken off the ihs, and I have removed it on the 3500. I guess that will be the next thing to do and see if I might be able to sqeeze a little more out of it. I have posted prime and 32m screenes earlier in thread. Here is my best 1m pass.
probably trying to nail down more market share and beat Intel to Xmas sales :)Quote:

So I suppose it's prime stable for somwhere between 8 and 19 hours; I'm comfortable with anything in this range. It was a warm day in NYC and the heat was on in my apartment, so ambient temps didn't help matters. I suppose I should be more than pleased at the prospect of running 2.9GHz at 1.44V 24/7, but to be honest I was really hoping for a bit more. Avarice is the right word, isn't it? Or is hubris better?
2) Removing the IHS brought about a mere 5C drop in load temps, a far smaller improvement than with my CABNE (roughly 10C). This was a bit of a disappointment, and potentially important information for others with similar weeks/steppings. Removing the IHS may not be the no-brainer it is with single core Opterons, but this fact obviously needs to be confirmed by other users. Hell, you know you're going to do it anyways.
3) Temperature continues to seem to be the ultimate constraint in my overclock, which may be good news for non-air users. Sustained readings of around 54C and above causes Windows to lock up (and occasionally to crash) while priming, both with and without IHS. (As an aside, I probably should seriously consider reinstallation at this point given the number of hard resets I have had while testing over the last two days. It is conceivable that some of my recent instability is due to OS corruption.)
3) In effort to moderate temperature, I threw on a torturously loud Vantec Tornado on my XP-90. This helped bring temps down another few degrees, thereby allowing more overhead for voltage. It is also driving me insane.
4) All this in place, I was able to boot successfully to Windows at 300x10 at just under 1.5 volts. Fought several hours to achieve prime stability. Unfortunately I repeatedly failed prime blend test after 1-4 minutes during the 1st 1024 FFT run. Increasing voltage did not help. In retrospect, it was stupid of me to have been trying to fight large FFT failures with Vcore - large FFT's work memory, not CPU! Silly rabbit.
Back on track, I then tried a few other sticks of RAM with the same results. After lots of futile experimentation with timings, I finally tried lowering MAL/Read Peamble to 8/5.5 from 9/6. This immediately brought stability to the large FFT tests. Again, I was stupid - this should have been the first thing I tried knowing that Opterons are sensitive to these settings. Large FFT's are now a breeze, even at low voltage. Incidentally, my single core CABNE likes those values too, which got me thinking...
5) Ran prime blend again, passed 1024K test. Moments later, however, I failed the 1st 8K test, indicating that though RAM was now OK, CPU was not. Loosened ram further just to be safe, then incrementally raised volts in attempt to pass small FFT's. Pushed up as high as 1.65V. However, despite increased Vcore, once I went beyond around 1.58V, Windows would consistently freeze during prime as load temps surpassed roughly 53C. 273x11 was no better. This complete instability at any voltage convinced me that temperatures were the dominant variable (I choose not to believe that I have simply found the chip's wall). Also, though one core oftentimes failed before the other, it was inconsistent in doing so, especially as Vcore and timings changed. I take this as a possibly encouraging sign that that core is not just a total lemon since it wasn't always first to drop..
At this point, I gave up on 3GHz on air for the evening. Will give it another go as I learn more; might try that undervolt burn in crap.
I have backed down to 2.95GHz at 1.49V. As a quick test of Vcore, ran small FFT's for 45 minutes without event. Currently priming blend at 42C. Though it has only been like two and a half hours, it looks like it's gonna be fine (certainly so with a little bump if necessary). Might even be able to back her down below 1.49 volts. We'll see.
Final thoughts: this chip reminds me a lot of the early single core CABNE's. It takes off crazy fast out of the gates at near default voltage. Temperature increases outpace voltage increases. It subsequently fails to scale well with voltage as a consequence of this heat. Indeed, in my case, 7% past stock voltage netted a 32% overclock, whereas 20% past stock voltage isn't even stable at a 35% overclock. Methinks it be time to invest in better cooling.
Anybody wanna loan me a prommie? :)

damn, now I am dying to get a better board, hahaha, I think I'll play with this lame biostar board to see what happens....time to add more to my thread I guess.. excellent data man, uh also, your air temps still seem just a tad hot, try remounting a couple times? I guess it must really be the ambient killing u there.
Well i got my CABYE 0540FPBW a couple days ago and this is what ive gotten it to atm.
http://members.westnet.com.au/danastas/1488v.jpg
This is using a TT golf 325 heatsink.
This is what i am running atm and is what i game at/ surf net everything at and to me its stable.
StressCPU gives up after a few hundred thousand iterations when the temps get up above 61degrees. At 1.54v it is stable untill temps reach 63-64.
The annoying thing with this chip is i cant get it to clock much higher. Above 3100 it wont stresscpu or superpi 32m for longer then a minute no matter how many volts i put into it.
Ive decided to be happy with 3ghz (hell thats higher then my original aims anyway) and will leave it at that untill i get watercooling in a couple of weeks.
Hey ixtapalapaquetl would it be possiable to find out what MaxTcase and thermal offset youre opterons have?
146 CABYE 0540 FMBW under Watercooling HIS on.
Ambiant Temp ~ 21°

This is just insane man 1.4V for 3000mhz :toast: awesome chip m8.
I hope mine will clock that good :slobber:
Sharky I hope we will get as good chip as Pt1t`s!... ;)Quote:

what about 146 seems cheaper but CABGE's ?
Cabge are not so good clockers in general 2.7-2.8 max
So far, This dual core opteron 165 is 100% stable at 2.7ghz @ 1.52V, the 2nd core seems to go down with anything over that... I can boot into windows and prime one of the cores at 2.8ghz though.. ah well, 2.7 isn't that bad :)
i need some help... with my venice my bh5 ran every divider up to max... now with opteroon div 150 dont work.. mem is @230 and i get erros :P but cpu is normal or bad... 1,55v 41 full load 2,85 ghz OCCT stable , IHS on
edit i have 0536 cabye
anyone what read preamble and max async should i use ?
i have 2x256mb corsair rev1,1 bh5 , with venice 3,6v @275 mhz
704-bta bios
I have 3 chips to test: an E6 stepping Venice 3000 and 2 Opteron 144s. The first of the Opterons is a CABNE 0540 BPMW from overclockers (co.uk) - their current stock, still waiting for the other from elsewhere.
In the absence of the DFI Expert board, I'm getting a cheapo ASRock Dual mobo on Tuesday and 2Gb Ballistix to test with the stock cooler. If there's a lucky winner, it'll go under a Vapo LS.
My attitude is that if they only do 1.8 GHz stock, I have no reason to whine - they're doing what it says on the tin. I think ppl tend to forget that sometimes. If it only does 1.7 GHz, then it's an RMA.
146 CABNE 0430 is unbeatable. :banana:
Here's 3050Mhz 1.4V watercooled ambient ~19C Heatspreader still in place.
