any dual core opterons done this yet?

[chinkgai]

the ultimate goal for my 4400+, which was only max stable around 2.9ghz, was to hit 3ghz for daily use at a reasonable voltage. it failed, altho it came semi close.

by stable i mean 10+ hrs prime stable, not some lame suicide shot or dual superpi32m

so out with the old and in with the new! i got a 4800+ instead of jumping on the opteron bandwagon!

my dream results:

prime stable

i didnt do any burning in or anything either, just popped her in and fired her up. at first i was accustomed to a 11x max multiplier so i forgot the 4800+ had the 12x max! what a pleasant surprise as i hate to run dividers.

my original goal was to initially start at 2.8ghz and see what volts would be required then move on up to 3ghz if its within a reasonable voltage.

keep in mind my 4400+ required 1.425*1.1 = 1.5675v to get 2805mhz

so i was hoping to reach the same speed with less than 1.5v

anyways, upon seeing the 12x...i jes immediately fired it u at 3ghz!! took a couple reboots to find the correct voltage though...but wow is all i gotta say.

Very impressive dude. Although I wouldn't want to pay that much for 3GHz. I'll just wait until 3GHz is the slowest performing AMD chip and buy it then.

Nice

 

[fbrdphreak]

Can we assume water cooling?

 

[Markbnj]

Wow, 12 x 250. Very nice. QQ for my 4400+. I want a 12x divider .

 

[biostud]

my X2 3800+ was prime stable @ 2650Mhz but had problems recieving data from internet sources, so I had to turn down the overclock.

huh? you're gonna be waiting awhile then...

 

[Hyperlite]

WC? Thats awesome man!

 

[chinkgai]

yes wc'ed but it can probably be replicated with air cooling (tt bt) since its only less than 1.6v

I am playing with some opteron 170 and 175's that are having fun in the 2.9gighz range.

I am waiting for a new powersupply as I am using a generic no-name brand and having lots of problems with voltage going all over the place.

This is all on air with stock AMD heatsink.

 

[chinkgai]

some? wow

prime pics when u get ur new psu would be appreciated.

I am playing with a lot of them...

Of course, the ones playing well at 2.9+ are 0530TPMW's

I am also playing with 165's

0534SPMW and 0541RPMW

Both seem to do about the same for me, around 2.7-2.8

I really wont know exactly until I get that new powersupply tomorrow.

This is on a DFI UT lanparty EXPERT with some Geil ONE BH memory which loves the 3.8V


I am going to take a 0530TPMW and put it under water next week, see if I can hit over 3gighz.


I will have more updates tomorrow. The powersupply is really kicking my ass.


Regardless, I am getting a good feel for what they are able to do. It is going to suck when I have to sell them (as I have no need for 6 processors)

0530TPMW's hmm i might have guessed .. what sort of voltage is required to run these frequencies, as i hear that 2.9 is achievable with less than 1.5. You'll find that a voltage bump to around 1.65 will not even get you past 3Ghz, this is what I have seen from quite a few people around the net on the same stepping.

I think it might be heat issues that are holding people back, and like you said once you stick it on water maybe you can achieve 3Ghz and beyond.

Good luck and keep us informed on your progress :thumbsup:

I dont have anything good to report because as soon as I start prime, I hear a buzzing come from my powersupply from the load.

Watching my voltage jump around is never fun.


Heat is a BIG issue! Remember, I am only using a stock amd dualcore heatsink. Lucky for me it is pretty damn good. I have a boxfan above the testbed to keep everything as cool as possible.

I will open up the powersupply for you guys to laugh at. I think it is "400watt" but it only has like 15A on the 12v rail.


The DFI board is great, so far so good with that. Currently I am rocking a low-power ATi X300 because I am already on a tight power budget with this test system till the new enermax liberty comes in (eh thought it would be fun to play with)


I made another post but nobody seemed to care, glad to see a few people care about these opterons still...

1000mhz overclocks on a dualcore is just great imho.

Nice stable high OC Chinkgai.. What PSU are you using? course 0530TPMW helps too No 165's are 0530TPMW..only 170, 175 and 180's I've seen like that.. and yeah they do pretty well.

Sweet. I just got my 0541RPMW 165 yesterday. Let us know how it does on low volts once you get it running on the enermax. I'll be putting it in an asrock mobo.

 

[chinkgai]

thanks zebo!

psu is pc&pc 510 deluxe or express...i forgot...lol

and stepping is 0538 RPMW by the way. same stepping but later week than my 4400+, which was 0524 RPMW

two things i noticed about the two cpus (ihs-less)

1. the 4800+ was not as dark (central core)

2. the 4800+ had a much more mirrored finish (central core)

 

[irev210]

Another update. I got my new powersupply. Voltage is better, still have a little flux, but I dont think you can have perfection.



my gem seems to be the 170, just tossed it up at 2.9, been prime stable for hours. Going to see how high we can go.


175 seemed to max out at around 2.9, what can you do.


Havent played with the 165's yet, this takes time.


edit, seems like the 170 will do 2.93 or so on air. Not bad I guess.


I am very happy with the enermax liberty, it is really quiet too. 120mm fan just sits at 900rpm and the unit doesnt even get warm.

 

[demenion]

chinkgai? wondering how your X2 does @ low volts?

My Opty 170 0530 priming at 2.6 GHZ @ 1.311V.

 

[cronic]

looks good chinkgai. please let me know what it is runnin in a month or so. I am very interested in figuring out why (in my opinion) the amd 64 seem to oc awesome when new and then seem to fall off by 100-300mhz fairly quick.

 

[chinkgai]

sup cron, my x2 4400+ never got any worse at my daily setting of 2816mhz @ 1.425*1.1

sure i'll let u know in a month or two but i dont think it'll get worse, esp not in that time frame of a month


i had my 4400+ since it was release by the way

That's a myth. Guys who never had comp stable in first place, rushed out screens of high clocks..only to find themselves a couple months later facing instability they had but never gave time to check properly. Another factor is temps. Lots of people have a winter clock pushed up to the very edge what thier chip can handle but when spring and summer come the increased temp puts thier processor into instability mode.

Chinkgai is a stud...Overclocking is not easy to do it high and well. Which is why I'm personally perfectly happy with minimal overclocks like buying the cheapest chips and making them like AMD's releasd top end. I'm lazy! I Don't have patience Tweaking, rebooting, flashing, tweaking, rebooting, testing, rebooting, tweaking, testing testing testing testing for days on end only to have it fail and have to restart all over again. With my idea of a "minimal OC" strategy you eliminate about 99% of the work since you're operating in defined ranges AMD feels is safe..

So where's the new crystalmark score?

I got a quad xeon box coming to try to keep up with you...
