The Official Dual Core Opteron Overclocking Thread

[-n7-]

Stepping:

OSA165DAA6CD
CCBWE 0551VPMW
139294AL50740

So one week after the infamous 0550s...

Only way past 2.6 GHz has been lots of vcore increases.

running
opteron 170 0546xpmw. 1.44v at 2.7 prime stable for about 1 hr. still priming. will update with final pics when i get the highest clockable prime stable thingy below 50C

edit: ignore this... prime crapped out at 30mins

CCB1E 0608 MPMW again

So weird I can get mine to run dual SuperPi 32M as many times as I want, but SP2004 fails in about 6 minutes for core 0. A strong CPU no doubt. This is killing my power supply though.

When did you order it and where from?

[aicjofs]

Monarch on March 23 or 24th for $280. Like I said early I was watching a HardForum thread like a hawk waiting, and when I saw someone get a CCB1E I just knew it was the right thing to do.(Because the CCBWE I had was horrible)

Removing the IHS always takes way longer for me. I never understood how people got it in like, 2 mins. I always take a good half hour to get it done. Maybe I'm just slow/over cautious, but whenever I cut thru all 4 sides, it never wants to come off...so I have to go around, checking all the sides, then pulling on the top, etc. When it finally came off and I saw how close the SMD's on the one side were to the glue I was like DAYUM! She's safe and sound now though, and I'm trying for 2.8GHz on stock voltage. I'll leave it go when I leave in the next 20 mins or so.

You have the wrong tool. I used to use a Xacto knife and it took 30-45min.

I just went topless on my new 0550 VPMW with the paint scraper. It only took 1min. It was amazingly easy and safe compared to the Xacto.

The paint scraper mimizes the reach of the razor blade. The razor blade is extremely thin and just slips into the rubber. Best tool ever for delidding: like a hot knife in butter.

Gotta to get one.

After removing the IHS:

Good
1. CPU stable 2.9G @ 1.39V - before required 1.44V.
2. Can run 3.0G @ 1.41V - not prime stable

Bad
1. CPU not stable @ 3G no matter what voltage
2. CPU temp may have increased? (AS5 not set yet? Reseat waterblock?)

Going topless seems to be a mixed bag. I was expecting cpu temps to decrease but hasn't happened. Voltage has dropped for the same speed which is very good. Do I need to apply more force on the waterblock?

If you are doing the same speeds with less volts, then temps have decreased. The sensor is off. IDK why 3 Ghz doesn't run... what's the memory and LDT multiplier at?

[Rufus7]

VPMWs runs higher on Ram Dividers the 183 and 166 are not bad.
And play with the Subtimings of the Ram. VPMWs are Primadonnas by the Ram Settings.

Received my CCB1E 0609FPAW today
It's not as good as Gorod's I think Temps were incredible high at watercooling so I popped the lid right away

Now dual priming naked @ 3GHz 38°C load @ 1.5V with 2GB's XTC @ 250MHz... So far so good

[Clint]

CCB1E 0609FPAW ..it's nice to see that some newer steppings are doing good as well...then I just might be able to find a replacement if I manage to destroy my chip when I lap it..

[Rufus7]

Nice Chip ChekDisk.
Better than the 0550UPMW a little bit less powerful than the 0550VPMW.
But so far very good.

Little update... Nothing tweaked yet... Just upped volts and primed

what ram timings are you using?

SLI-DR bios 623-2 yellow slots
(no orange slots my mobo hates this, hates 704-2BTA would only do 2800 with 1.43v (no prime testing)...on 623-2 I can run 2800 at default vcore if lower mem speed way down)
2 x 1GB GSkill DDR 500
OCZ 520w Powerstream
X800XL
dvdrw
audigy2


I have 170 0550 VPMW batch 136 that will load and run winxp at 2800@default vcore but it needs to use a 100 divider 1:2..anything over and it will not run xp

temps suck on air but this chip will dual prime 95 at 53C small fft and not crash on air..BT
Idle temp is 37C
load temps 2700.. 48C, 2800 50C+

I primed the cpu last as quick for 2.5 hrs on small fft on 3/4 divider for ram at 200..load temps were 52/53C@1.43v bios...@1.4v it does prime core 1 ....memory controller is the issue....I tried 9/10 divivder at 1.43v..runs xp but dies prime right away on core 1

It do load and run xp at 3Ghz on 1.5-1.55v..but no go on prime at all even 1:2 divider..seems memory controller is too stresses as it craps prime right away..so not a temp issue

this VPMW is ok on higher temps...however this may be affecting the memory controller????

the memory controller just can not seem to run 2 gigs

I am going to try 623-1 if its on Tmod bios cd...I was surprised at how much my mobo hates 704-2BTA bios

Does your DFI under report? Like, does 1.35v read as 1.31v?

[ChkDsk]

Like all... But I'm looking for lower volts now, allthough temps are ok.

Oh, and trying the newest beta bios... No issues so far!

Just picked up this one:



It turned out to be a CCB1E 0609FPAW stepping and not the EPAW

Right now I`m givin it a burn in at 2.6ghz default vcore under my tdx.

Exactelly the same as me... Only batchnumber differs.

When did u have to raise vcore from default?

atm i`m at 2.7hgz default vcore.

2.8 was a no go Started @ 2.8
and since 2.8 was a no-go for core0 I upped the volts and gave 3.0 a try. Worked out for me

core0 is a bit weaker btw...

U started at 2.8?

[ChkDsk]

U started at 2.8?

hehehe, I've owned 2 165's and the did 2.8 @ max. Found it a nice spot to start at. Think 2.8 needs 1.4 set in bios for my chip. Core0 is solid @ 3.0GHz but 3030 fails.... Thinking about some more volts
Should I?

Same stepping from Monarch runs 2.7 @ 1.30 and 2.8 at stock 1.35... Love the temps...
