I give 420$ for a opteron that does 2.8 Ghz primestable on air.
if 3.0Ghz needed 1.50v and underload temperature already close to 0, then I would assume it's possible that you might need 1.6v for even 3.1Ghz, your underload temperature probably will shoot up to +5~10'C. I'm sorry but you might not crack 3.2Ghz to do prime unless you yank the IHS. double check your mount and see what happen.Quote:

I was thinking about removeing the IHS tommorow if it does'nt prime how can I mount the evap head on the core without cracking it when tightening the screws.
I am not 100% sure about phase change, but with a waterblock, simply put some little round rubbers (like those on AXP).Quote:

Here is how I prep mine:

looks very nice Ben :worm:
Popped the copper top off my Opteron. Was fun. Soaked it in Oops! for a hour then ran a electrical-taped hobby knife around the perimeter and it fell right off. The silicone sealant they use is rubbery and can be scraped off with a plastic "instrument" (something plastic and hard).
I reattached the IHS with two dabs of silicone sealant at 2 edges and used AS5 on the core. I noticed when I removed the IHS that it looked to be only making solid contact at the middle. What probably happens is they put these IHS's on and then dont put pressure on them and they dry without properly compressing all that sealant and paste. And the paste they use hardens somewhat. Now, my temps are down 7C or so and I definitely have some more headroom. Nice.
Careful with the pins tho! Use the foam pad it came with or you will bend them and there are a TON so it's a pain to bend 'em back. I bent a few and that was enough. Scary stuff there.
Put the Opteron next to a true man's CPU for scale reference. :)

Is there someone that has take off the IHS from an Opteron 0550 UPMW (better if 175...) and use AIR COOLING?
If yes, please post result before and after the surgery!

I'm now running my Opteron 165 0550 UPMW at 2.5 GHz/278 HTT on 1.26V (1.3 V in BIOS), 0.05 V below default. :) I haven't gone further, I'm stopping for the night to see if it will crunch 2xSETI until tomorrow, then I will continure to clock higher again, or lower the Voltage more. Temp 52 C under SETI load with my Thermalright XP-90 air, all fans set to quite low noise level. ;)
Earlier I managed to creep Super-PI 1M stable at 1.28 (1.325) V up until 2.67 GHz/298 HTT, but I'm not sure if the chipset (1.6 V) or the CPU gave up there. When I upped to default 1.31 (1.35) V, it crashed out earlier on 285 HTT for some reason. Temps reached 60 C during Super-PI. :nono:

1009 bios.
I personally found it to be more stable than 903 and less buggy than 703.
Hope this helps
Don't know if this is true but I have heard the CCBW1's have something in common with the FX60's ;)Quote:

I'll attach screenies sometime later.
Just threw in my 165 and its running a little hot. I only have it at 225x9 1.3v and its at about 40*c idle. I might of used too much as5, but I did tighten down the Big Typhoon pretty tight so I don't think it should really matter. Any suggestions?
Hi, I have an opty 165 CCBWE 0551UPMW which max out at 314x8,5= 2,7Ghz with 1,6 volt. Pass dual super pi 32MB n dual folding for 12 hours, but can't get higher result on air.. Seems like week 51 aren't good chips:(Quote:

You might want to remount
I'm disappointed with my Opteron 170 0546SPMW brought from mwave.com, which can only reach 2.45Ghz /w 1.45v. :( memtest works fine but superpi crashes in 5 min @2.5Ghz /w 1.5v. Didn't try higher vcore because my PWMIC was over 60*C (CPU was about 42*C though).
I'm thinking about getting a Big Typhoon (currently I'm using the stock HSF /w heatpipe), but I doubt it will help since the CPU temp isn't a problem.
I've always used lots of as5, and never had any heat problems, even with my current Opteron 170.
Just my :2cents:

I bought my 165 from there a week ago. It too isn't such a hot overclocker. But I popped off the IHS and it gave me about another 100MHz at the same voltage. Almost 10C drop in temp even with the IHS reattached with AS5 and some silicone. Mine was only making good contact with the center of the core, and the paste was hardened leading me to believe that the IHS wasn't pressing against the core well.Quote:

That sucks about your CPU! Unfortunately, overclocking isn't guaranteed... I've been really happy with mine so far. I can do 2.6GHz with near stock voltages, and 2.7GHz with 1.45V. I've got a CCBW1 0550VPMW... I wonder what the difference between the CCBWE and CCBW1 is. Aside from that, your CPU is only one week off from mine.Quote:

I've been following this thread for about a month and now I'm all confused. Information overload if you ask me. Can someone answer me this: What stepping should I look for to get 2.7ghz on air with low voltage?
