Sure of course in the Near.

Got a couple of 144's in on thursday. Got one in a system last night and went to town. CAB2E 0540 FPMW, Neo2 Plat w/ 1.c sideeffect.

Screen Shot:

Still working on it, runs Prime95 stable for hours at 315, won't even hit windows at 320 so we might have a bit more headroom.

lol rufus, i meant the 148 is nowhere near the 146 even though there same steppings ;)

Sorry tatts. thx for the Screen from teh 148 CABYE 0540FPBW.
Good clockers. Nice clocks. Not so good as my CABNE but very good for a Productionweek.

no problem ;)
you saked for results of a 148 so you got a ss of 146 & 148 with same steppings to compare them :D

Both are very good, i will eventually buy an 148 CABYE 0540 FPBW pretested at 3Gig and 1,48Vc on Aircooling next Week.My HS sucks next Week i will take him off. hoping for better Temps.

Current test run - 310x10

Not so good for an Vapochill cooled Opteron.
Here´s a little Steppinglist from Germany.With all Opterons available for S939. ;)

Glad to see they have that running again. That's a very good thread.

Didn't anybody notice Moonman's OC? That pretty much pwned.

It's good but not great. The reason is he is on phase. That means nonpwned.

OSA148DAA5BN
CAB2E 0540 FPMW
Batch 0166

Still working on getting this one tuned in but so far completed OCCT @ 2800 (10 x 280 1:1) with 1.32v.

Question I have is that the CPU seems to be running hot at 47C max during test. According to Central Brain Identifier Max T Case is 63C with a Thermal Offset of 12C. This compares to my old 3700 Sandy at 59C T Case and a 3C Offset.

Would this explain the high temps and if so how should I account for the 12C offset?

Very good cooling. :)

CABGE so it's great.

That temps are very close to early CABNEs...Interesting :)

Are new chips really falling over at this low MHz 1:1? I know there's something in my system that's not letting me run 166 divider on my CAB2E (that would mean 2.5-3-3 ~250 on TCCD, which is fine) but is fine with 133 (2-2-2 ~200) - could it really be the chip?

Reached 3000, nothing exceptionnal for this stepping, but it's the first time for me in the AMD world.

I ran Prime 10 hours last night at 296*10 (same vcore)

RAM timings are pretty relaxed (running 166 divider); I'll try to run 200 or 180 when the CPU has reached its limits.

Those opterons have an unusual behavior: Usually when I need to bump the Vcore I know the chip limit is 200-300 mhz higher. Here I had to raise from default Vcore at 2700 (And thought it would be difficult to reach 3000 with "raisonable" voltages), but it's still going! Very impressive chips indeed.

how's this for fast :)

Opteron 144 cabe2e 0540 fpmw
Cooling: Thermaltake Silent Boost (21dBA 27.5cfm - i.e rubbish fan!)

Temperatures are a bit warm due to low cfm fan. Unable to max out the RAM ATM due to no active cooling in place

Yep, all these CAB2E 144s seem to be doing about the same on air/water - 2.9, give or take.

It'll do 3GHz, but it takes 1.64v.

Opteron 146 cabye 0540 fpbw

my wonderful 146 CABYE 0540FPBW now on watercooling & advancing very nicely, 35C idle 41C full load :toast:
still priming before going for the 3.3ghz :banana:

Help! Help! Help! could anyone show me the results and screenshots of opteron single core running at about or something 3.8GHz if i'm not wrong, i think the fastest superPI run... i forget to bookmark the link...
