The Opteron Skt 939 Overclocking thread !!!!

nightic · 2 Nov 2005 at 12:07

So far so good.
(Super Pi time not great - RAM at 200MHz with plenty going on in the background)

CABYE 0540FPBW - 3.00GHz (300x10) - 1.525v (BIOS - 1.488v CPU-Z).
DFI NF4 Ultra-D (704-2BT)
CPU MaxTCase - 63C
High flow top DDC/G4/Maze 4A/BIP III/Papst 1200RPM
Nasty 'Titan' thermal compound used (no point wasting the good stuff for speed binning)

Now just 4 more to test...

i'm starting to wish i'd ordered a 146 instead of a 144 now! Let's hope the 144 cab2e's will go to 3ghz!

Just FYI, CPU core will be @ 1.53 approx. under load. Ignore CPU-Z and any other program except a multimeter.

I measured mine (DFI Ultra D) after killing a nice chip because I thought the CPU-Z reported voltage was accurate, so went over 1.75v actual, maybe 1.8v I don't remember.

ditto snow patrol, feeling a bit gutted atm!

Just waiting for the cab2e results, but I have a feeling they will not be as good

just my luck..

Yeah, no doubt about it Jimbo, just included the CPU-Z reading as it seems that (incorrect/false as it is) this is the figure many people quote when reporting their CPU voltage used.

Just noticed cpu-z lists mine as a skt940...very strange

dun worry, I will take it to 3Ghz tmr when I get home

CT_Nuts: CPU-Z not updated yet , and you still 0.01mhz short of 3Ghz

Brocon · 2 Nov 2005 at 12:35

as long as they hit 3Ghz on air with out silly volts I will be happy

not asking that much really, is it!

Well if it is poor it will have to be sold and I will get a 146..

Bossman · 2 Nov 2005 at 12:51

Still no worthy 144 clocks?

...

Brocon · 2 Nov 2005 at 12:57

so annoying, my kit is at home and I can not go home until friday :'(

Won't get to find out until then..

very nice

what are your volts & temps like?

Someone at XS has been able to post at 333x9 on 1.35v. Not stable, but it could only mean it needs the volts taken up very slightly. :cool:

1.450v in bios and 35 degrees idle.

Brocon · 2 Nov 2005 at 13:10

he also says his mobo is playing up, can not wait to see what the 144 CAB2E can do on a DFI/epox.

cheers mate, looking very promising

now im wondering if i should get a vapochill :confused:

The majority of these Opterons have the cold bug so it may not be worth it.

2nd CPU seems like it should scale about the same as the previous one.

CABYE 0540FPBW - 3.00GHz (300x10) - 1.45v (in BIOS - 1.408v in CPU-Z).
DFI NF4 Ultra-D (704-2BT)
CPU MaxTCase - 61C (2C lower than the 1st CPU)
High flow top DDC/G4/Maze 4A/BIP III/Papst 1200RPM
Nasty 'Titan' thermal compound used (no point wasting the good stuff for speed binning)

Edit - This one's actually doing a little better than the first, despite the lower MaxTCase.
Bumped voltage to 1.475 (in BIOS - 1.440 in CPU-Z) for 32mb Super Pi pass:

Do they? whats the symptoms? the only one i've seen is yours. I'm holding off for a few days till I order one I've got a vapochill LS at home waiting for a good chip!.
