How well does your Opteron overclock?

Super Nade · Nov 30, 2005

*Note to self* All entries complete and sorted, 25 June 2006

Please post you Opteron overclocking results here instead of a hundred threads. It would be helpful for everybody. I will make a list of steppings and overclocks, linking them to your respective posts.

A few words regarding the burn-in process I use (Warning! This is very time consuming!):

Memory is at stock or any guarenteed stable setting. I will be using StressCPU and CPUBurn. Goals are to achieve a higher stable OC at a progressively decreasing VCore, aided by conventional burn-in.For Dual core CPU's, I would recommend burning-in both core simultaneously. Ther is usually one weak core, which may need a bit more work to bring it up to par with the stronger core. Extra burning-in should not hurt, so keep working with both cores simultaneously throught the process. As always, I mean run two instances of the toasting programs

Just to put things in perspective, with my Venice, out-of-the-box, I could hit 2.55GHz at stock volts, but getting to 2.6GHz necissitated the use of 1.65V! This was prior to the burn-in. After the burn-in, I'm comfortabley lodged at 2.77GHz @ 1.64V. I followed this elaborate process with some measure of success. It may or may-not work for you, it did for me.

Stock settings for 6hrs (StressCPU)

Bump net CPU Freq by 50 MHz for ~~1 hr~~ (Edit*4 hrs) (CPUBurn with error checking off). If you computer crashes,back off by 20MHz.

Check status for 30 min using StressCPU. If you find errors,bump voltage by 0.025 V and repeat step #2.

Continue this process till you reach your Magic number/Target Freq (mine is 2.7GHz).

Turn off error checking and use CPUBurn for > 14 hrs i.e overnight.

Turn off computer, let it cool down and then use Stress CPU to check for errors. Let it run for the rest of the day. If you still see errors, you have not completed setps 1, 2 properly and have jumped the gun. Don't be hasty!

Now decrease VCore in steps of 0.025 V and see if you get errors. The idea is to reduce the voltage threshold by this back and forth process.

Format you could use:

Code:

CPU Type: Single 144,146 etc or DC 165,170 etc?
Stepping:
Best Stable OC:
VCore:
Temps: Idle/Load

A slight clarification on the poll. By saying 1.8 - 2.2 I mean 1.8 < = x < = 2.2,
and by 2.2 - 2.6 I mean 2.2 < x <= 2.6

I really hope this is merged with the "Which Opteron do you have? " thread!

Some Analysis:
Not much data to draw any conclusion amongst the 144 series.

With the 146 series, the critical parameter, surprisingly was the week code alone, i.e 0540 > everything else. There is no clear cut demarcation between CABYE/CABNE/CAB2E without taking the 0540 into account.

With the 146 series, the earlier week CPU's offered a lot more than the later week codes. Note that the VCore varies, but I'm saying this because people who have the killer results have them because they can get there whilst the other's can't (or so I feel).

With the DC 165 Opty's week 36 (my CPU) has proved to be an excellent one. I'm more than happy! The rest are quite good but lack that extra boost.
Clearly the week 30 Opterons are kings. Just take a look at Ninjawreck's scores. He has killed everybody else in the Dual core arena!

I'd be glad if you guys can point out more correlations/patterns.

*Update*
Looks like the 0550 OEM CPU's are excellent. Looks like they may be on par with the 030's. The key is to cut down on load temps. We see load temps hitting 50+ C at modest voltages. There is a bit more headroom if temps can be controlled.

What degree of stability are we talking about here? It'd be nice to say "superpi 32million" (which only takes about 1/2 hour.) or something for a minimal stability standard.

Good statement. I recommend adding a field to the format, stating what they used for stability testing. I will edit my previous post to include such.

Any thing you choose to do

I'm going by the honor system here, people may have different ways of testing for stability. I personally prefer 2 instances of StressCPU. If you say its stable I'll take your word for it.

BTW- edit the title for grammar. it's "how WELL does your opteron overclock?"

Unfortunately, I realized it the moment I posted this, then I encountered a BSOD, it was too late to recover by then. Forgot to open the Windows

I'd say we break Davids toes first then his legs, just can't let the toes go to waist can we, I'm just happy that I got a good x2 that is able to keep up with the operon, but I would like the extra cache though. Anyway, you guys could contribute to the cpu database in the frontpage and add your OCs.
