You're right about the voltage, i set 1.425V in bios and in windows it shows at 1.39V
Still, it's pretty obvious these cpu's run very fast at very low voltage.
Have to see about DC, it might need a tad more voltage, i will report back as soon as i have new RAM. ;)

Well, here is a prime pic of my 144er. For prime i had to run with 200/166er, and my BH5 are at the end.

Freestylercs, is that the CPU from ebay? :D
Can you do OCCT at that speed/voltage?
I got my opteron 148 from Ewiz earlyer this day
its a Cabye 528 GPMW
so far i have reached 3125 as max clock for 3dmarks and 1M super pi
This is on water with the IHS on (i will get a LS in a couple of days and i am not sure if the evap can make contagt to the core if i go naked)
Super pi 1M at 26,422 sek @ 3.125mhz :banana:
3Dmark01 40.288marks @ 3.120mhz :banana:
it is prime stable at 3ghz @ 1,6 v.core i wont go further because it runs very hot
Do they top out even if you drop the main bank of timings to 2.5-4-4-8? What voltage are you running them? The rest of the timings should be ok, nice 3ghz btw :)Quote:

the last 4 digits is 0100...
tomorow I will test... I was especting a cabne , the guys from compumusic told me that ... but I was lucky it wasn´t a bad stepping.
Going for my non-clockgen 3ghz screenshot....I am a little worried that my pwm temp is high, its TOUCHING 60c every now and then :eek: Is that ok? And yes my memory tops out no matter what the timings are it seems. I currently have the RAMv set to 2.7, but I have tried 2.6 and 2.8 as well. I really can't believe thats its a problem with the sticks.
60C is too high. Anything above 55C and your chip is in the danger zone. I don't like it to go above 50C personally.
What's it's maxTcase?
i'm starting to suspect some issues of contact between the IHS and core.
i got my 148 CABYE today as well and even at 1.45 volts, mine is starting to hit 60C's with OCCT stability test. (2.8 ghz).
with my 0517 SD 3700+ it never hit above 53C's with 1.6 volts... or do these opterons just run warmer???
Wow that is high, thats a reading from the area around the chip that controls vcore. Try to get a fan blowing on the heatsinks on the mosfets. Maybe you're having a problem with your board? You have all 4 power connectors plugged in, correct?Quote:

Ahh, sorry. IMO, 60C is still too high for PWM. But I'm a cooling freak anyway. :)Quote:

I can't see the IHS causing that much of a temp difference unless it wasn't making good contact.Quote:

Got my CABNE 0528GPMW from compumusic today :) I think mine would benifit the ihs removal but it doesnt break 48c load on good watercooling.

So does this mean I am being limited by my PWM? My cpu hasnt broken 40c yet....I wanna keep pushing it...I think I am going to need 1.6somthing to get to 3.1ghz spi stable.
Well, my ram is pissing me off still but here it is....3ghz pi stable. :banana:
My PWM was pushing 60C the whole time...my CPU never broke 40c.
i never saw mention about a fan on the top corner of the board. i have a 120mm up there to keep all the important mosfets and ram cool.. pwm is idling at 28c for me
What stepping do you guys think the new 146's on ewiz has? Anyone get theirs yet? I noticed the ewiz 148's are CABYE.. so maybe 146 are too..
Sorry I'll just be so pissed If I get a CABGE, it will be a big downgrade from X2 at 2.67ghz
I am running my SD 3700 verry stable at 2900 using BIOS 310.
Will the 146 Opty run the same or should I upgrade?
What are you guys using ?
Ordered mine from ewiz last wed and I got a 148 CABNE 0528 GPMW
Well My first 30k run in 2001 :toast: :toast:
http://service.futuremark.com/compare?2k1=8759049
It was with default x850xt and My First 3 gig run :) man its fast and faster than my x2 4400 everwas..
Was running the Ballistix 11x273 with 1.5v on cpu.. Guess I could try less volts but wanted to make sure it would make it lol..
Thank you AMD for a great chip as I got a vience, x2 4400 and nothing come close to this..
How did you get a Cabne? everybody else is getting Cabye from Ewiz, including me. Ordered mine last Monday.....Quote:

i was hoping for 2.9 to 3.0 with 1.5 to 1.6 volts but seems like temps get too high for me.
and i agree NYCTeeN82... strange he got a CABNE while most others including me got a CABYE 0528GPMW.
well i ordered a 146 from ewiz which should be here Friday. i'll be sure to update and let you guys know how that one does.
This thread convinced me to jump on the bandwagon too :D Yesterday received a 148 CABYE 0528GPMW ordered from ewiz on friday. Pretty happy with my current 3500, but thought I'd give one of these a try. No time for testing now, hope to post some results this weekend.
