they need to be a lot higher try 9/8

this mushkins redline can do something like that(i do that now in this moment)

even that you think this timmings is fuc**** my oc?
with the firs settings i can guet 265 fully stable

**dinos22** · 10-06-2005, 05:58 PM

Opterons need those timings relaxed for high HTT....don't ask why

with the settings you told i cant boot

i put max async latency at 8ns and read preable at 6ns
any others sugestions

my windows is a litle broken but i will try
tanks M8s

**Vapor** · 10-06-2005, 06:18 PM

try async at auto and preamble to 7ns

**NISCO PT** · 10-06-2005, 07:23 PM

GREAT FUC****** BANANAS youre right

youre the best
great tanks from portugal

**dinos22** · 10-06-2005, 07:35 PM

so 7ns did the job

**Vapor** · 10-06-2005, 08:05 PM

Looking good there Nisco--can you get any more out of it?

**WesM63** · 10-06-2005, 08:07 PM

*writes dram timings down..... prays for "CABNE 0530APMW"... and anxiously awaits opteron*

**BioPC** · 10-07-2005, 02:44 AM

Somebody else with a CABGE? please post your results!
I would really be dissapointed if my ordered one cannot overclock to more than 2,8Hgz.

**HermS** · 10-07-2005, 05:48 AM

Further testing:-
32m stable at 3405MHz

Here's one, but I don't think he loosen up his async timings and preamble.

Seems this steppings likes a lot of voltage.

Seems this steppings likes a lot of voltage.

Ram /166 , preamble 5ns.

Look that vcore !

but my water is hot

This CPU like Voltage, but isnt hot ! Highest temp during a SPI 32M @ 1.80v is only 42° (23° in my room).

**TooRUde** · 10-07-2005, 07:25 AM

Ill have some screens up in a sec currently at 2.8 with my opty 146 from vandi.
I had some major problems that lead me to stay up till 4am trying to fix my computer. My raptor drive decided to get all corrupted.
luckily i havnt had to increase the voltage yet, still 1.39. I hope this means I can reach 3 - 3.1 without having to go above 1.55.

Currently running under xp120 (30c idle 39 / 40c max load) till my new tubing and resevoir arrive, then I'll be placing it under my lovely Storm G4.

thanks again vandi!

what stepping is that?

**mbm** · 10-07-2005, 07:53 AM

Where can this cpu be bought?
I cant find it anywhere in stock

Well loosing up the preamble like its been told in this thread. And 1.84V is

too much.

Go for an FX 57 instead... You'll get better results!

This might be the hardest thing I've read lately to believe. I'm not saying I don't believe in miracles, because I do, but to be at 1.8v with a 144 and only be at 42c on wc(or is that 42f?) is truly a miracle. Let's see a sg ss. Make me a believer.

**Ferry82** · 10-07-2005, 09:34 AM

I just saw a 3200mhz before it reboot @ 1,48v with Xp120+Papst@1600rpm.

42°c

, with the 3200+ got 44° @ 1.65 with the same motherboard.

Please show ss of sg and 32m pi of 144. On a 3200 I'm sure you got 44c in wc.

**sponge bob** · 10-07-2005, 10:53 AM

those 144 looks bad, so big voltage compared with 146 ?!

ffs i ordered 144

That's just sick mate.

Tested some more tonight.
Results:

Over an hour Prime stable (stopped the test myself) at 3000Mhz 1.45V
OCCT test stable at 3050 1.55V
SuperPi 32M@3100MHz 23min 22sec

SuperPi1M @3140MHz 26.235 sec
CPUmark 99- 414 (3140MHz)
Sandra bandwidth 8426mb/s (316x10)
Hexus PiFast@ 3140MHz 37.95sec

Still, it bluescreens running SuperPi 1M at 3150.

Impressive low voltage CPU i'd say.

You need to wait a bit, the last stepping didn't 'look' good because only one person tried that stepping.

Maybe finnaly try to oc the vpaw with relaxed async a preamble and give some screenshots of superpi,cpu-z and a64tweaker.

Till now every opteron did a good job. I am sure tomorrow will follow more screenshots because 50 people received 536VPAW today.

**Techmasta** · 10-07-2005, 11:25 AM

Any ETA when these will be available for purchase?
