The Official Dual Core Opteron Overclocking Thread

i just got my 165 today, its a 0551VPMW, and so far its very frustrating. At first it was prime stable at 2700 w/ 1.52v. I ram prime for about 2 hours and then couldnt take it any longer and went to play some BF2 with my new X1900XT that i just got today too. I come back after playing for a few hours to run some more prime and one of the cores just takes a dump within 2 minutes. OK, i reboot and try again, it :banana::banana::banana::banana:s out in 1minute. I reboot and give her 1.55v, and it still poops out in 1 minute, WTF? Now i have to put it down to 2.6Ghz for it to be stable. I dunno what the heck happened. I remounted 5 different times using 2 different thermal pastes. It does run hotter than my 170 did though. Even under high end water it hits 40C under load at 2600 1.49v. It seems like it REALLY would help to strip it down to bare core although unlike my 170 this is a retail CPU and i have an actual decent warranty.


EDIT: I realized that my instability started when i flashed my X1900XT to XTX. Maybe its drawing more power and causing the OC to become unstable? I ordered a 170, and for now its at 1.44v 2600 and running 24C idle 37C load. I notice that at 1.47v 2700 is more stable than 1.53v. Maybe im stressing my PSU out too much...

Decided to test this 170 on air and here is what I got :D :D



2.90Ghz @1.4v (BIOS 1.42v)



IHS is off, room temperature 70~71F', case is fully closed. Not sure why my PWMIC is hot as hell even with copper ramsinks on the pwmic chip, R60, and all the hotspots, have a 90mm fan blowing across the ram and the PWMIC area as well. Chipset fan is also replaced with the copper VC-RE. I'm pretty satisfied with the good ol' air result. :D :toast:

Well done on your OC Ben why don't you run Prime a bit longer 53 minutes is hardly proveing a stable OC, 1 hour primeing just gives you indications of what the chip "could" do and not what it really does. Do you go for benching instead of daily use stable?

my PWMIC also gets very hot with the Opteron not upto 70 but close.

Komplett.no got some 170`s right now.. Think i sell my 175 0550 and se if the 170 can do 2.8 stable.

Everyone has different preferences in overclocking, it's a lengthy process with lots of other tweaking and factors involved, but long story short, for me...once I found the lowest vcore that could cause and trigger the prime to failed within the 20min windows, usually all it needs is an additional 0.05v vcore along with few other changes, 10 out of 10 times I can prime atleast 12hr straight, and hours of BF2, Quake4 and FEAR afterward, if I'm only interested in benching then I would of leave it at 3.0Ghz @1.35~1.375v instead. So you're wrong, 2.90Ghz is what it does, NOT what it "could" do. I have no intention whatsoever to leave it on air, I did it out of curiousity so once I'm done playing with it then this puppy will crawl back under the phase and will be clocked back up to 3.20Ghz @1.52v for 24/7, I could careless IF this cpu can only prime at 2.1Ghz or 2.2Ghz on air as I had already knew what it did under single stage phase. :D :D

By the way, Prime is hardly the only indication of stability, just head toward the Bandwidth section and do some reading on all those Ce6 memory threads, you can prime all day all night long or even weeks or months straight, but if you can't run any 3D or game, then all bet is lost :lol: so "stability" really depends on what you use your machine for.

Its not like you payed for x amount of speed and you got less than that.

If you read with attention my statement above, you will able to understand that i'm NOT expecting that "...AMD start makeing sure that the higher models overclock more than the lesser ones?" but I think it's absolutely LOGICAL and more suited to basical law of market to use BETTER materials and BETTER productive process for the high priced models, so what i say is NOT directly related to OC matter ---> if you want, you can call this a question of principle.

That's all

I think my 170 its a "normal" 170 :p:

Try lowering your voltage rather than raising it. It could be a heat problem... I just had a 165 that ran almost 10 degrees warmer than any other opty I owned

Ya...this Dual-Core Opterons are very hot :confused:

Are batch numbers related to steppings? IE, I just got a 0551UPMW 0324.. so does that mean its earlier than my 0551VPMW 0671?

Batch is in second Line important!
1. Stepping CCB1E0550VPMW is very important
2. Wafercharge>1378678L505XX<3.Batch.
You need first the right Steppingweek, than the right Wafercharge!!!
And after all the Batch in the Area of a known good going CHip.
Batch is only Luck.

:idea: What would a fan blowing on it do for the almost 70 temps?

You have to put an 120MM Fan over your Mosfets.
Best Fan is an Silenx ixtrema Pro with 63cfm/h at 14db noise.
Like this one.

lol your 23min prime theory won't be understood by anyone new or "outside" your head thank you for explaining whats the Batch No 408?

Rapty Prime should heat minimum 2-3hours.

Rufus, if you've read any of my post, you know I really don't like to prime. One hour is more than enough for me. However, I have my 170 on a BT testing it and just for my EU friends I will let it run a little longer. Will 2.5hours suffice?

BTW(s7e9h3n is teaching me what all these letters mean) I can not afford a $27+ fan to blow on my mb.:(

dogsx2 for me its equal what your testing.
But here at HWLXX Forum you´ve got to make Dualprime 24.14 over 3H to get into the List.
But of Course it is sufficent with 2 Hours. Most Errors are coming in the first hour or first 30Mins.

Than you can take an Scythe 120Fan costs only 15 Dollars.

http://www.pc-cooling.de/de/SILENT-P...+-+120+mm.html


in my system there are 6 Silenx working at 12V.

Here's what I've got my CCB1E 0550 running for now.. 1.4v set in BIOS. I'm very very happy with this chip! :D Got it OEM off ebay a week ago. The prime times are different because core 0 failed at 308 after a couple hours, I set 306.5 :rolleyes: in clockgen and started it again.

Rufus, 6 fans????? I'm German/American and only can afford a cheap 120 Y/L fan. What is the link for that forum?

your own thread "Prime stable but not game stable" pretty much explained why you don't understand, as I said.... priming isn't the only indication of stability and there's lots of other factors involved in overclocking. :D

Thats the Link for the fan how it lokks like and how much it costs.
The Link for the HWLXX Forum you will get now.

4 Fans on the 2 Black Ice Extreme II Dual Radiators and 2 Silenx Fans in the Case.

Repoman Nice VPMW.
But you will see if you use the 180 or 166 Ramdivider it will run with less Vcore or one Core will not Suck down under Prime.

Maybe im not understanding u correctly, but from what i get it seems your saying that when u buy a 175 that they dont run at the rated speed? Cause thats really all amd cares about, and logically thats all they should. It would cost them alot more in testing to figure out what every core was fully capable of and use those in the higher models, versus just makeing sure they do the speed that they are labled to do.

Well decided to do some burn in and longer run dual prime sessions with lower volts and looks good to me still with 170 0546XPMW

Well maybe you could add to my thread instead of being a Defensive ignorant when your asked questions, your not the only one which can Overclock a computer but you carry on like you can. and giveing a one sided story & brining up problems which was'nt included in the initial question is childish and pathetic its just a easy way of beating someone down and winning something which I'm not even competeing in your one of those point scorers only one sided disscusions that are meaningless for the other party & can offend some individuals or I could be wrong and your a young adolescence. Now if you want a sensible discussion please answer my question to you about the batch or better yet you could help me with my overclock instead of laying into me with pathetic innuendo's.

Otherwise bring it and handbags at dawn.
