Very :( If it's CCB1E that is. I wouldn't even bother

there goes my plans for phase change out of the window :rolleyes:

Yup, same here

Though the new OCZ thing is supposed to sustain ~0C temps (I think?) maybe they can handle that

The CPUs i've tried were coldbugged even at +1c.

Maybe if you mounted bad and pumpted 1.65v and left it dual loading with +15c you could run on a single stage, but it's hardly worth it when these things are hitting 3.1 Ghz on water :)

CCBWE's are doing ok on SS?

yeah

The CCBWE are known to be OK with moderate below 0 degrees

I can only push my CCB1E 0550 VPMW at 2.85 at 1.390 ATM. Anything higher, it craps out. Hmmm.

I just got my opty 165 ccbwe 0551upmw in the mail from monarch.

Anyone know if this is a decent stepping? Wish me luck.

Should get to 2.7 pretty easily, but hard to do 2.8

Knob, what kinda temps do you have? Should go much higher.

alright, these few days HK are cold, last night I stressed my opty165 for about 8 hours at default voltage (auto in BIOS), @ 300*9 ~ 2.7GHz

yahoo widgets tells you the ambient temperature.:banana:

Thanks bro, and it was you that gave the word...I guess I owe you one :toast:

I have tried 3GHz, primed it for 20 min on 1.39v...but as allways with this particular chip temperaturemanagement is essential.
If you keep the temps in the low 40's it scales perfect up to 3.2GHz...so a watersetup is the key here...but you know that already..;)

And you're doing it on air? Your chip is definitely better than mine by .5v at least. Get some watercooling quick! PM me if you want help piecing together watercooling.

This chip is just guzzling volts. Sorry for complaining about my chip in almost every post, but it's really irritating me that I didn't go for the 0550 on eBay in the first place (when CCB1E's were first released) and that I went with this chip instead, but I guess I can't do anything about it now.

EDIT: What is up with SP2004? Only detects the boot speed, and doesn't seem to detect any clockgen adjustments.

If it makes you feel any better, 2.8 Ghz isn't a bad overclock for a 165, it's still +1Ghz. The 170s are crazy clockers though.

what a strange forum,

1.34v @ 2.7GHz is not appreciated while 1.52v @ 2.8GHz is Bravo :clap:

good forum, that's remarkable, I'll better stay away from here.

P.S. my opty 165 can do 2.7?!:confused: GHz at default voltage

He's working on a week 47, you have a week 50. Your overclock is quite good as well, just on week 50s i kinda expect 2.8 GHz. It's a lot harder to achieve it with a lesser CPU. Not like you have to prove yourself here; if you can do 2.85 Ghz show it!

When you say *default* voltage is that set to AUTO in BIOS or did you manually set 1.35vCore?

alrite, just assume only 2.7GHz can be done on 1.34v. is it good?

posted above.

coz if you need 2.8 or 2.85GHz dual sp2004 stable,you have to wait one more day after I am back to home and run the test.

auto in BIOS, it is 1.34v usually.

k thanks, I noticed on my board that if I set AUTO for vCore in BIOS it somehow adjusts the vCore itself according to load.

Did you notice the vCore fly up when your system is under load? (using AUTO vCore?)

it flies lower to 1.32v sometimes :(

OK, how is everybody getting over 2600 on an Opteron 170 with air?

I find with my Antec P160 case and Thermaltake XP-90C with Panaflo medium fan on it, that temps are 48C when going at 2600 or above. I am a bit wary of pushing the temps too high.

I have the XP-90C installed with the large portion extending over the chipset, not the RAM. I also have the fan blowing into the CPU. And, I've used AS3, not AS5 as the thermal compound.

Should the 0550 VPMW run much cooler than 48C at 2600 in this configuration?

Yeah, i was mostly loading in the mid 40s with low volts, only when i pushed volts to 1.48v did i see 49c, on my AC Freezer64 Pro.

I have the Enermax Liberty 500 watt power supply and Asus PC Probe shows my voltages fluctuating at 3.34-3.36, 5.08-5.1 and 12.03-12.1.

Are these values OK or too high? Could they be contributing to my high temps?
