Hmm with 1,4 * 113% in Bios i got 36° idle an 50-54 load @2950mhz, eve stock clocks/volts idle is 31° and load 41°. I'am on water cooling and my venice 3200+@2800mhz@1,62v did 25°idle and 43° load. So what the f**k is goin on here :) . I'am too scared to remove the heatspreader :( Anyone ideas how to burnin ? I mean prime fails after 10 mins @ 2980 and these volts. Another problem is that vcore fluctuates 0.2v, did i listed all the problems ? Yes i think i've got it all ;)

Looks like I'm a bit unlucky. Maximum stable clock I can get is around 2.75GHz.http://www.xtremesystems.org/forums/...chmentid=38453

You need more vcore for sure. I don't think with the vcore your using yours is that bad. You are the only one with a CABYE thats posted a 32m ss. That means you are at least pretty stable. The other ss of the CABYEs are only 1m or 8m, along ways from 32m. When the 32m ss come in we will have a better idea how they oc.

Iceman do you have an CABNE or CABGE?
CABNE not need much Vcore for high Frequences. But they heat very good.
Here a Pic under Load of my CABNE on AIrcooling.

can 2 hours of Prime compare to SP32M? I gotta get back to CS:S so no time for Prime:p

i left it on CPU burn in last night for 5 hours with 1.54V 2.9GHz and did a 32M run with these settings now.....i'd say 1.52V would probably do the job as well.......it's a slooooooow time.....lots of tweaking ahead :)

Yes, 2 hrs of prime is stable, it's more then I want to do. I would just like to see 32m run, it doesn't take 2hrs and it shows some stability. No knock on your prime. :) One thing for sure, burning does help.

That looks good, with some burning you got a good chip. :thumbsup:

WHERE DO I ORDER THIS CHIP?

Sorry for the caps but can anyone please tell me? thanks.. :slapass:

No shouting. :nono:

If we knew, we would tell you. If you have read any in the AMD section, you will see they are very hard to find. When they do come in stock, they sell out right away.

Where all these people buy then? black market? :confused:

Yes....the black market.

Well, some of us got it from a private dealer who's all out while others buy it when a store that has it in stock is found. All stores are currently out of stock.

Yeah, I'm thinking of getting an ultra-D, so I can get more vcore, and also get the most out of my RAM. Currently using Patriot TCCD, but it's wasted on this board as if I use a higher divider, I'm stuck with 2T. I also have some Twinmos I can use (UTT I think).

As far as SuperPi goes, I think it's misleading to use it as a stability test. Highest prime I can do is 2.7Ghz. Highest 32M superpi is at 2.75GHz, but prime fails instantly at this speed. 1M superpi reaches 2.8GHz. So prime95 is the only stability test I would trust for 24/7 settings.

Just to check....everyone with an Opteron is running 7.5ns as the Pre-amble setting, right?

It's good for finding how well your processor can do and gives a big boost over AUTO (typically--my auto defaults to 7ns :rolleyes: ).

You could use a different mb for sure,

I don't want to get into the prime debate, I thought we were showing ss of our new optys? For that 32m does show some stability. However much testing you want to do for your 24/7 is up to you. No matter how long you run prime, it could have failed 1 minute after you end it if you would have left it running.

i've used 7ns ..............do you think 7.5ns is better
10-12-2005, 03:59 PM
Vapor

They're probably about the same....but most people probably left it at AUTO which is 5ns or so--these won't clock well at that setting.

I think that's part of the reason why we're seeing worse OCs--in addition to CABNEs simply being better. ;)

Time to wait for my Opteron 146 to arrive..

Wondering what stepping it is....

Sorry, didn't mean to start a debate, just wanted to note the discrepancies in my results between the two. In fact, it may have been down to my own mistake. Because I've just changed my preamble from 7ns to 7.5ns with A64tweaker (thanks to Vapor) and prime and superpi are giving much closer results now.

my mobo is defaulting to 9.5ns with a 100mhz divider :stick:

i just tried preambled at 7.5 and i lost 1sec on my 1mb score in super pi ... not sure if it made anything more stable or not but i deff lost performnce atleast in that benchmark. ill leave it at that setting and see if it helps me any....

thx perc,

What was your previous pre-amble?

Great tip! Thanks!

Couldn't figure out why prime kept failing at exact same point again and again (during test 1 8k after initial 1024k series). Looks like this solved my problem.

Thanks again!

ok well i went back into bios and set pre-amble to 7.0 instead of 7.5 i gained my second back. then i riased the oc to 3100mhz and ran again got a nice 26sec in 1m super pi...

peace perc,
