Well got occt to run the first time at 2.5 got voltage on cpu to 1.425 and i tryed that The Max Async Latency to 8

well i run my 146 at 2.8ghz on 1.44v with ram on 3/04 divider so its at 200mhz. running timings of 2-3-2-5 at 2.8v, not tried lowering volts yet

oh thats the corsair 2gb kit

Just warming up a new CABNE 0545 Opteron 146, straight in and priming at 2800Mhz with 1.5V (just picked these values randomly).

I dont have those options as I only have an NF3 250 motherboard

Use A64Tweaker from this page to change settings on the run.
I have my 146 CABYE 0540 running pretty quick on air, the trick is to use a MAL of 8 -/+ 1 with the opty.

How you getting on with it, Ive been trying to find some results with this CPU stepping, with no luck.. most people are saying that the batches are not as good after week 43, probably the same people who have been saying amd is ctoppring production of these opty's!

Ive just got one, but as of yet have no hardware to test it on.. just wanted to get one before they disappeared....

Would be very interested to know... :-)

Opty 146 Cabne 0545: at the cpu voltage displayed in the attached image it failed prime95 after half an hour.

MikeTimbers · 17 Dec 2005 at 16:01

That's not surprising with that speed and that low voltage. Take it up a bit, say 1.5v and re-try Prime

Yes, did just that

Clint · 17 Dec 2005 at 16:39

Did turn down the voltage a bit, the Opty seems to be quite happy at low volts.
What do you think of that HTT freq? 400Mhz!

..all it needed was 1.3 on the bus, rest is stock voltage..(or lower)

The DFI board is awesome.

My first try at OC'ing, playing with it...

..this is fun!

I got my opty 148 running at 264 x11 / htt x3 / 40c idle + 48c load / and mem timings of 2-3-3-5 / super pi returns 1m scores of 30s and 3D mark05 scores of 6398! reasonably happy with this.

rxmac · 17 Dec 2005 at 17:32

Picked my opteron up today, it's a 148 CACJE so not the best of the bunch where overclockings concerned but hopfully it will outperform my 3500 winny. Wont be able to try for a few days but will keep you all posted.

Any guesses as to what i might be able to acheive?

harris1986 · 17 Dec 2005 at 20:34

i'd say 2.8ghz easy

Clint · 18 Dec 2005 at 17:49

After some playin' with it, check the voltage..

..I'm thinking HTPC...

Clint · 18 Dec 2005 at 18:50

Ok, gonna stop buggin' you pros, but I can't resist...

thats under 1 volt.. :cool:

yeye, I know...here we overclock and so on...but admit it's kinda cool.

Hesky82 · 18 Dec 2005 at 22:24

nice one clint! just wondering, which rev ultra-d board do you have?

Penfold99 · 18 Dec 2005 at 23:15

well got mine at 2.6 at 1.425 volts, i cant seem to get it to run OCCT on anything higher, even with more volts to it?

megatron · 19 Dec 2005 at 01:20

Put the vcore on +0.1v, and test it again. If it does the same thing then, up the chipset to 1.6v and then the htt voltage is it still wont pass. Then try underclocking the memory to see if u get stability if u need to.

cutchy2k · 19 Dec 2005 at 01:38

Heres the best i can do, not sure why either, i rekon its the mobo dont like anything above 310 htt but i might be wrong,

Link
any ideas how i might get this any higher?
