Ok, after testing my 146 CABNE 0530APMW overnight, it seems to need a little more volts than some of the other ones like it to clock really well. This might be due to my board, or my cooling.
My max case temp of the chip is rated at 65degrees. I'm wondering how hot is too hot to run this chip safely.
I need more than 1.5v to prime any higher than 2900mhz. At that voltage, prime causes my chip to run at about 57 to 58 degrees under load.
I want to go higher with my clocks, but I also am afraid to damage the chip.
what do you guys think.
Should I go ahead and push a little further, or should I stay where I am until I can get some water cooling in a month or two.

From what I understand CABNE=fx quality, CABGE=sd quality, thus cabne is best.

With cabge went to about 2450mhz on stock vcore....
After that it needed upping al the time.
I seemed to be stuck on 2800 now cause my mobo can't give more vcore
(neo platty with 1.36 bios)
Temp barely exceeds 50c on load with thermaltake beetle
(45 with bios 1.8 up)

here's my thought. i don't have any evidence to back this up other than the sightings of some FX CABNE's and the temperature issues..

you know how the turions have "low power" transistors that run cool, but also don't clock quite as well?
instead of putting in more low power transistors, replace them all with "high power" transistors that clock better, but draw much more power. this explains both the scaling, and the temperature issues with the CABNE's. :toast:

It seems to be very weird. More and more people with the 536vpaw reporting high volts and considering the high volts a low temperature.

In 2 weeks another batch of opterons will arrive, we'll seen other results very soon.

The amnt of voltage tht tht CPU can take is nothing short of amazing, I never thought tht I would see the day were an AMD CPU would return to the high voltage loving tht this particular batch of CPU's seem to like.

While many of us r struggling to keep the temps down, it seems it is an effort to get the temps up with tht particular batch!! Keep us updated with those results, i think I will continue with the burn in, my CPU dosnt seem to want to run 3Ghz prime stable, but thts another story.........

I see you have 144 cabne but are awaiting 146, I am looking to hit 3ghz prime stable with an opteron. Is the overclockability of the 146 that much higher than the 144? What's your current prime stable max oc? TIA :toast:

those are questions i would like to know myself ;)
as stated before, my board is out. i never got around to doing any long term stability tests, especially due to my suspicions of having a bad board anyhow. i know i could do stock speeds with 1.025v rock solid :toast:

i'll have the answers soon though :toast:

I donnt know if s it here write,
bur the most important is TMaxCase
much of CABNE is 65 and you can go to 3GH and over
but a lot of CABGE have 57 and max is 2,7-2,9
better TMC = better OC
and question is if this set will by still same at time

I know that this was to ozzimark but I would like to address it as I do have both a 144 & 146 same stepping cabne. Here is my take so far.

1. Both cpu's hit 3000MHz at OCCT stable with ease. The 144@1.4v and the 146@1.45v.

2. With very limited testing on good air the max so far is 3050MHz-144 and 3080MHz-146.

3. I think these are no different then the venice in that the top oc on the very good chips are all about the same max,ie,the x doesn't mean greater oc.

The other thing Ive notice that has nothing to do with these cpu's is that there are sure a lot of dfi mb's that go bad. Mine went bad right after I put the 144 in it and another new dfi board lasted a day and it went bad. Now that I have a bad mb, I notice that there are a lot of them go bad.

While I am expressing my thoughts, here's another. I'm not sure it makes a difference if you burn in at stock MHz@ lowest volts or highest MHz@ lowest volts. I've always used the latter and will do so until I see hard evidence otherwise. I think it's a ymmv type thing. However, I do think it does help to do one or the other.

CABNE is more hot at the same Vcore and frenquency that a CABGE ...
It's maybe not only a diff of quality (Silicon) ! I don't know more ... but more me there are a other diff.

This OC is brought to you courtesy of Perc

Thanks to Perc for sending me a mounting bracket for my Prommie. My "modded" bracket was having a hard time getting a good seal on my DFI which lead to the death of my DFI SLI mobo. I'm working on modding my non-SLI DFI so I can get some SLI action going. In the meantime I decided to try my EVGA mobo that I got in a deal that you can read about here. If you read that thread you'll understand the limitations of that mobo which makes for a theoretical OC maxium of 3.45ghz when the 148 is used. The 314HTT limit really makes putting the 144 or 146 in this board pointless. Maybe a bios revision will fix this.

Right now I'm working on getting it stable at this speed. I'll check back in when I find the max stable.

soon i'll be able to comment on the same thing. i'm banking on the 146 to be better than the 144 by a good margin though :D

by that theory, my 3700+ newark, which was revE core... should have been simply amazing, being rated to 95c core temps ;)

I'm talking about air cooling and nothing else. If you look at the air cooled optys, there not that much better then my 144@3050. I hope you get a cracker jack 146 that will do great but still stand by my statement that a really good 144 isn't going to do that much less then a 146. Look at the world records, there is not a lot of difference top to bottom on most.

Also, look at the thread Team Japan has. There is not a nickles worth of difference between the 144 and the 146.
10-09-2005, 04:28 PM
goodcooper

so far, is it only the OEM chips that have the CABGE?

computersmas were all OEM iirc...

maybe they havn't gotten to the packaged models yet, maybe if we hurry up and snag some retails we can get the good stepping...

i just hope Vandi hasn't lost my PM :/ i havn't heard from him and its been about 4 or 5 days (can't remember now)

Those are still good looking clocks for a free mb. Glad to see them doing so well under phase.

peace perc,

As a bencher ... not so much. But as part of a budget SLI gaming sustem there is a lot to be said for it. Is "budget SLI" an oxymoron? I picked up the hot budget bencher, the Asus 939 with the ULI chipset. That might be a good one to get until the "expert" comes out next month. I'll start testing the Asus as soon as I can.

I have to keep reminding myself they were free when I'm wrestling around with one. Its an annoying board sometimes. The funny thing is ... the two 7800GTs are still in their shrinkwrap while I've spent a lot of time with one of the free mobos. :D

Thanks for the response that's the info what I was looking 4. I cringe at the thought of my DFI dying on me (I'm on RMA rehab right now and happily holding strong... so far), I've heard a lot of sh&&t about DFI's dying for just about anything and was quite content that I never encountered such issues, but this... Is there a reason why this happens or does this happen with a specific bios? :slobber:

I thought it was time I had a little fun so I dropped my pair of 6800GTs into the EVGA mobo and did a quick and dirty run on 3DMark '01. Nothing like a big CPU to give that benchmark a bump.

Strangely enough I consider this my weakest Opty because of the way the volts/speed scale. Its not from the "magic" 0530 week. I'm testing it right now because my DFI is not ready for SLI (yet) and the EVGA stand-in won't do much with the 144 and 146 because of the 314HTT limit. I'm wondering if anyone else who ordered from EWiz also got the oddball CABYE stepping.

Volts are the same. 1.62v.

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. :)

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.

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.

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

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

http://www.xtremesystems.org/forums/...id=38318&stc=1

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

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.

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

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.

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. :nono:

My full stepping code:

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.

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.

Alot of assumptions are being made abt similar chips! My CPU is of the same batch as Zeus and your own, but it is an impossibilty for it to run 3Ghz with 1.4v!!! Unless I have a poor mthbrd this chip will never be able to run at the speeds and voltage you r assuming i wish things were different ;). I have no IHS, am on water with a LRWW and nothing else iin the loop, but still need vCore greater than 1.5v to even think abt getting prime remotely stable. Could you please tell me wht I am meant to do!

Zeus,

thanxs for teh information, I understand your wearyness for using a multimeter for vCore point. I asked this because I want to know if your '1.42v' is actually tht. For me '1.42v' with my multimeter is 1.49v!!!. So if we are going to say tht our chips are prime stable with 1.42v at least we should be sure tht this is a fact.

I will try your timgs with my chip, hopefully I will be able to get prime95 stable, at the moment I havnt passed more than 2hrs without it crashing :(, maybe i should switch my wireless connection off, to see if im getting crashes because of tht. Our before i forget, which bios are u using?

Mongoled,

I'm using bios 623 that came as stock.
Prime large ffts failed after 46 minutes at 1.4V

Gonna burn in more with small ffts.

Before i ran a night Prime with small ffts at 1.45V 3GHz large ffts always failed within 30minutes, now it's 2hours+ stable at 1.45V at large ffts.

Gonna do small ffts at 1.42v tonight. :)

Ok I will try burning with small FTT's also, Ive been using the blend test to do my burning in + 'CPU burn-in' program. Im ok booting into windows at 3Ghz with 1.4volts im doing tht right now, but as soon as I start prime, boomf it fails

Sierra and myself are using the CABYE. I'm not sure which week he has or the rest of the code. He of course is just tearing it up with his posts. I'm hoping mine will close the gap when I get it in a better mobo. Wish he would have indicated his air/water limit, but he may have gone straight for the sub-zero cooling.

You might have better luck asking the leprechauns where they keep their pots of gold. :p: j/k I'm sure someone would post if they had a source - right after they get their shipping notification. Read through the posts and you'll find the online stores that have shipped Opty 939. Then with multiple browers up on those stores, keep refreshing until they come back instock. Be patient, it may take a while. :D

I have different values for these, but i doubt they will help my chip run stable with 1.4v! Ive been running small ftt's for an hr now with 1.52v bios (MM==1.59v!!). 1.4v impossible, hehehee.

Sorry, I should have posted that info earlier. My chip is CABYE 0528GPMW. I went straight to phase change cooling because I wanted to know what the CPU could do frozen. I'm an impatient person. :D ;) The chip will eventually go into an air-cooled system.

I had some heat-related issues a few days ago because the IHS was apparently not making good contact with the core. I re-seated the evaporator head and now everything is fine. I'm very close to getting the Opteron to complete SuperPI 32M at 3.5GHz. But I think I need 1.67v and that puts a real strain on the system. Will keep you posted.

I thought I read an earlier post that said they talked to Monarch and they said they would never sell them. :confused:

That's like I talked to the DFI office today about a rma so I then asked for sales. I asked the salesman when the experts were going to be out. He said he was getting them today and they would hit the streets by Friday. :rofl:

Sales people generally tell you what you want to hear.

If you know German, please tell me what the cooling is in the #873 post this thread for the German opty oc results. Thanks

it locked up on me about 10mins in while i was setting up to prime soooooo lets see what 1.4v does at 3gigs same settings as above. also i rember someone saying that with thier tccd theyhad to change from 2.5-3-3- to 2.5-4-3- to get stable you think i may have this problem or 1.36v just pushing it for 3gigs. also if these 0530APMW CABNE chips are realy fx core wouldnt they run a 200mhz oc or even more with the chips defualt v-core? know what im saying?

Maybe these are the CABNEs that didn't make the FX-57 cut but were supposed to?

Either way...they're about the best deal you can get for ~$200.

The high Pre-amble requirement still makes me curious....like these were meant to be Opterons and were made in the FX production line.

You got an old verison of MaxTCase that shows 940, the new v1.03 shows 939. Also your 67c is higher then my 65c on my 146. Burn in helped both my optys.

You'll see that just a little bump in Vcore really makes a big difference in being stable.
