Here are one of CABYE 0540 APMW....it seems really cold even with VCORE of 1.53V...in the picture there is a qucik setup...I will burn it and will try to push it further...

Idle temps: 20 - 22°C
Full load temps: 35 - 37°C

This is with HS on, under water cooling room temperature is between 18-20°C!

Maxtcase is 59°C.

Will report if I can get further...for now is Super_PI stable but not prime stable

Regards,
Primoz

My ampw runs hot !! Like 50-52°C on 1.55V at 2.9-3ghz.
This with WC and IHS on.

MAxTcase is 57°C and 44.1Watt
Full stepping:

CABYE 0540 APMW

Now what is my batchnumber again because i forgot which numbers the batch was.

[Primoz78]

Stragne...I have never reached 40°C with this APMW...even under 1.586V...this is really cool...

Lp Primoz

p.s. Maxtcase is 59°C and 50watt...

havent i explained in the other thread what the problem was??

anywayz, i switched the ram back to slot 1&2 and everything works nicely

Not really, this was your post -

problem is solved thoug
it is 1000000% stable @ 2.8GHz @ 1.45V stock cooler
stock cooler => TT BT
would be nice
which grid do you need for lapping??

You never stated what the problem was....

But thats cool that you got it fixed.

[shimmishim]

anyone using the dfi board notice if they get more stability when they are NOT using the 4volt vdimm jumper?

i was trying to figure out why my chip wouldn't do 3 ghz anymore after switching from 2x1 gig crucial to 2x512 bh-5. set jumper so i could get 3.4 volts to my ram. then noticed chip wouldnt do 3 ghz anymore.

figured it might be the instability caused by the jumper.

switched the jumper back and now the chip ran 10 hours of small fft prime with no error.

anyone else do any testing of this sort?

my problem was instability
but not anymore, had to switch the rams to other slots

seems to great difference between the APMW's , going till 3.1ghz@1.56V till 2.9ghz@1.57V etc..

why won't my opty do 270x10, 280x10, or 290x10 stable? it BSOD's after a couple of minutes in Prime95, no matter what CPU voltage i select. My mem can do up to let's say DDR630 1:1. Also, i read in this topic a little and found out that a lot of users who want 2900 are using the 9x multi. I also have a lot of problems using 10x multi, but 9x is fine. How come?

Some initial info on the 148 0543 FPMW's that seem to be coming from multiple retailers as of late: [IMG][/IMG] [IMG][/IMG] [IMG][/IMG] I did not try a 32m with the 2905 speed. These were to be thumbnails I thought.

no probs here with 146 CAB2E 0540FPMW and 2x 512MB XMS3500C2v1.1 BH-5 using

is anyone here using anything other than a DFI board? im using a epox 9nda3+ (nf3 ultra) and was wondering if it could be holding me back some? Ill probably be upgrading when the next ati/nvidia refresh occurs.

[GoThr3k]

i am using MSI

[pazza316]

Guys could you help?

Any of you using phase change cooling?

When does the cold bug kick in on average with Opteron chips?

If any of you have found a work around for the Cold Bug with these chips and single stage please post.

Thanks

[Captin Insano]

Things you could try. get your voltages set to where you want them for your OC. Then be sure to have A64 tweaker and Clockgen allready downloaded on your rig and ready to run. I would also recomend a program that will put a lil load on the CPU when you fire it up. This will put some heat in the chip and help against cold bug.

So when you boot into windows run (i use Super PI 32meg) program for load. I would recomend doing this at about -24 to -25 celsius for boot up. Then using Clockgen change your values of FSBand Multi to where you want them for OC set in place and then tune your mem timmings with A64 Tweaker. if you prefer to do A64 tweaker first thats fine. Try that to see if that helps.

This is with a stock Vapo LS

Inital run up

The chips run hot once they get going so no Cold-bug at 'stock' LS temps from what I see

Here is the same chip on an Asus A8N SLi - Deluxe .. limitation is the MB as Mx HT is 320 & 2T - then SATA controller drops the RAID.

LOL I'm using an EPOX 9NDA3J with a 144 Opty but damned if I can get mine past 283HTT locks after that. So If you figure anything out let me know,

[kemist]

Ive had it up into the 300's, have you tried upping the board volts? I was asking mainly cuz i was wondering if the board could hold you back in general. In the anandtech reviews they make it seem like some of the boards allow higher overclocks than others all other things being equal. Basically im asking if anyone went from something like an epox or msi and saw better clocks and if thats common or not.

Are those 0540 FPMW's or do I read it wrong

hi I'd like to know when AMD is going to start selling more opteron 939's BECAUSE THEY ARE ALL OUT OF STOCK EVERYWHERE!!!!!!!!

Next Year in January perhaps Eduard.
