    Exactly what I was thinking, welcome back s7e9h3n!

    Have you been in the future?

    BTW I love the Task Manager screenshot with 24threads!

    As someone said, where in Europe are you?

Max possible for DDR3 1333 eight channel is ~85GB/s so this is ~48% efficiency atm, in comparison to ~80% on the quad socket istanbul system with DDR2 800 (theor. max ~51GB/s).
    Particle here has an dual istanbul setup, maybe he can run a few benchmarks for comparison. Maybe stream at the same cpu and nb clock speed.

    Whoops--almost forgot about this. Here's a run at default for me. I think I must be doing something wrong. Not sure how strongly effected by ECC this is, either. I run with ECC set to maximum protection. Come to think of it, this may be with underclocked memory. Let me check...



    Default: 12x2200, DDR2-800, ECC Off...not a whole lot better

    Particle's First Rule of Online Technical Discussion:
    As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.

    Rule 1A:
    Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.

    Rule 2:
    When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.

    Rule 2A:
    When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.

    Rule 3:
    When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.

    Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!

    Random Tip o' the Whatever
    You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.

    Ohh thanks, those results look like single socket vs. dual channel.
    Do you really have all four channels populated and ran with 12 threads? Beside that with six cores sharing two channels this benchmark is heavi imc speed limited. My 955be and also the AII 240 and 250 get best results if the nb runs one notch below the cpu. I hit a limit once the nb speed reaches 2xmem speed, so the optimum with ddr3 1333 is 2.8GHz/2.6GHz cpu/nb. If it's the same with DDR2 you should not be limited by the stock nb speed however since it's already above 1.6GHz.

    Beside that I think only this ES has unlocked multis and voltages and the retail chips will be locked so using k10stats or similar to modify these settings on the chips msr register will not work and oc capability will be limited by the max possible ref HT the boards will offer.

    @s7: I'm curious, what msr register did you modify? Was it the controll register or the p-state-0 register?

    FASN8ing (times 3).
    I really hope some of these new G34/C32 boards will be made with "XS
    people" in mind.
    Definitely sounds like there is a 2P market here.

    Many thanks for sharing S7.

    - Dual Opteron 2427s (Istanbul) @ 2.2GHz CPU/2.2GHz NB
    - Each CPU has two 2GB DDR2-800 DIMMs installed in dual channel configuration

    The numbers are just lower than I'd expect.

    Particle, Maybe it has something to do with the chipset difference?

    Check your numa settings in the bios you should get around 20MB/s in that benchmark, just like the other dual socket shanghai/istanbul setups.

    Hehe This thread started so long ago I'd completely forgotten to watch Fudo. I thought they'd pick it up quicker.

    Didn't they get it wrong though? this is 2x CPUs right? And all of the benches were run with 2 CPUs right?

    Looks like the CPUs were definitely throttling:



    This run is over 1 sec faster than @ 3ghz.

    Don't know how much I'll be playing with the setup today as I'm dead tired from my trip.

    Could you please test with WPrime v1.55, then it's easier to compare to hwbot.

    can u try Cinebench run? And winrar benchmark?
    wprime is better with the same HT: NB (2000:2000, 2400:2400 etc). Example with 2000MHz HT and 2600MHz at NB is run whorse. But i think, u know it

    WPrime 1.55 seems to have issues detecting the proper number of cores.....

    .....so does the Winrar bench:



    Cinebench has the same problem as well...don't have a screenshot at them moment, but I'll post one later....

    I think he can't adjust it.

    This is not an overclockers board......if he could adjust he wouldn't be writing scripts to OC all cores he would just flip multis in bios

    Yep...frequencies aren't adjustable. Only multi:

    1.55 seems a lot slower:
