Congratulations Nisco my friend .
Here in Portugal everyone is happy with your result .
Congrats for the great wr

Now i want so c some real hardcore benchies , get some 7800gtx and let ir rip

**Riverna** · 10-10-2005, 03:26 AM

My opteron 144 without heatspreader, 2750 runs with 1.28v

**ocZZ** · 10-10-2005, 04:00 AM

nice one Nisco

**goodcooper** · 10-10-2005, 04:50 AM

nice riverna, so far it seems the CABNEs don't need much voltage at all...

that is a CABNE right?

EDIT: yea, cabne i see it in your link in your sig.... NICE!

**Richdog** · 10-10-2005, 05:05 AM

Damn are these available to buy anywhere in the UK yet?

I heard a rumour a couple of stores had limited quantities but i'm having zero luck so far.

Best bet is to queue for cpucity.co.uk preorders like the rest of us

Last I heard was mid-week arrival hopefully

**Richdog** · 10-10-2005, 05:17 AM

CPUCITY is about £10 more (including delivery) than a couple of other sites though. I've seen it for £115 including postage @ scan.

Someone on OCUK forums said there was a UK store that currently had a few in (including a couple of 146's left)... just wondered if anyone knew it.

Oh well, i'll order from scan i think and endure the wait.

m8, theres no S939 Opterons at Scan

**Richdog** · 10-10-2005, 05:28 AM

There will be in the next few days... I talked to the guy who runs the shop...

Wondrous inventions these telephones aren't they?

Plus I get free P&P for being a member of a certain forum.

**DesertShooter** · 10-10-2005, 05:28 AM

I Can buy a Opteron 144 cabye 0536 gpmw, is it a good one? I have only seen CABGE 0536 VPAW, no CABYE 0536GPMW

Thanks,

If thats the case then I'm sure much better UK etailers will have stock too, and I personally wouldn't give Scan a penny (but thats a different story

)

Lets just hope theres still some decent Opterons to be had

**Richdog** · 10-10-2005, 05:41 AM

There's a horror story about every etailer in the world, all I care about is the best price with a decent reputation.

I wonder how good the first batch into the UK are going to be... seems we have a history of gettign the worse performers if the first batches of mobile Bartons were anything to go by.

**Perc** · 10-10-2005, 05:56 AM

ok my turn! just got the thing installed and went right for the money! i set the oc to 280x10 running the chips defualt voltages 1:1 ofcourse and let her go. she booted right up and everything seems fine. need to run some prime and other such fun programs to find stablity. well not bad for the first 5 mins i say now let see how high it will go. ill be back

stepping is the same as everyone elses 0530APMW CABNE batch number of 0022 looks good to me.

peace perc,

**Richdog** · 10-10-2005, 06:13 AM

Nice one Perc, getting straight to 2.8Ghz without any tweaking is always a good sign I s'pose.

**Zeus** · 10-10-2005, 07:04 AM

After a bit of work i got 10x300 1:1 Prime (large ftt) stable so i will use that for 24/7 setting.

I might get it stable with a little less voltage, will try tonight.
This is watercooled with heatspreader still on.

**gulp35** · 10-10-2005, 07:18 AM

What about the CABYE's? I've seen some for sale on ebay and the like but I haven't been able to find anyone overclocking them.

**gundamit** · 10-10-2005, 07:56 AM

Not a huge increase. I have to get them on some water before I get serious. If I get the cooling on and one of the Optys in a benching board I think I can move up a bit on the 7800GT Orb list.

**halcy** · 10-10-2005, 08:14 AM

Can anyone point me to where I can get a CABNE 146 for around $200 in the states?

Thanks!

(PS anyone try oc'ing this on an asus board?)

Hey Zeus very nice overclk!,

Could you tell me the water temperature for your runs, also if possible do you have access to multimeter so tht you cam measure vCore from the board. Im interested to know wht your 'real' vCore is.

The last line of my CPU code is:

1288864x50036

Id like to know if your last 5 digits are similar to mine and finally are u using tccd, if so, can u post an A64 tweaker screen shot, and tell me your values for 'drive strength/data strength'

thanxs

WTF?

Temps are ok < 47C load.

CPU interrupts due to broadcasts on the Ethernet.

Assuming you are using Windows, you will have a lot of useless boradcasts on your LAN, and each of them triggers an interrupt on your CPU. The OS then runs a high-priority interrupt handler with delicate locking (timing).

This hardware interrupt handling is an order of magnitude more complex than the normal context switch between OS and your application and hence is more fragile.

**Zeus** · 10-10-2005, 10:14 AM

Guess what?
Priming away now at 1,42V as we speak large FFT for over an hour now.

I'm not gonna poke around on my mobo with a MM for the sake of a Vcore value risking to kill it, sorry.

My full stepping code:

OSA 146 DAA5BN
CABNE 0530 APMW
1288864G50176

I'm using TCCD RAM at 300x10 2,5-3-3-7.

Here are my settings:

edit: martin, thanks for explaning, no problems now.

Nice Overclocking Zeus.But very high Temps at Load on 3Gig.
Youre Vcore is high for a watercooled APMW.
Try to get it under 1,4Vc. Than the temps will fall.

Best Temps you get around 1,376 or 1,360Vcore. And it must be enough for the 3 Gig.

**Zeus** · 10-10-2005, 10:20 AM

Under 1.4V??
I sure hope so, right now i'm at 1.42V but will try 1.4V later on.

**Rufus7** · 10-10-2005, 10:25 AM

My APMW under Air only needs 1,376Vcore for Prime Custom and that minimum 2 Hours and the IHS ist still On.Now i have booted with 1,328Vc CPU-Z. And i can use Windows normaly. Here the Screen. If you don´t believe it.And i´m using the 510-1FIX Bios.Look and believe it.

And thats the Prime Screenie for 1,36Vc
