    Sandy Bridge 2500K/2600K Batch and Serial Numbers

    in Sandy Bridge (P67/Z68) OC

    Posted

    guys i found this one on a german site:

     

    http://www.hardwareluxx.de/community/16325676-post1246.html

     

    Asus Maximus IV Extreme: Multi 53/54 (54 nur mit 99,2)

    Asus P8P67 Deluxe: Multi 53

    Asus P8P67 WS Revolution: Multi 53

    Asrock P67 Pro3: Multi 52 (aber höher nicht getestet)

    Gigabyte P67A-UD4: Multi 52

     

    Mit dem UD4 lag das Maximum bei 52, es lief einfach nicht höher. Alle Boards mit selber CPU und Ram getestet.

     

    translated:

    the guy used the same chip and same ram on different boards to figure out the max multiplier...

    Gotcha. That doesn't apply to the Asus boards when you OC with turbo multi though does it? For example most of my chips can get to the windows load screen at 55x+ turbo multi but they can't actually get past the windows loading page into the desktop. Testing on SS now and tested high volts, doesn't help me get higher and none of these chips is going to actually finish booting 55x+.

     

    this is a quite interesting information - thanks for sharing :)

     

    edit: so finding the maximum multiplier seems to be more easy on gigabyte boards?

    Thanks for the input guys!

    Binning Sandy Bridge is extremely easy.

     

    - use HS fan with easy mounting

    - set Vcore to 1.55V

    - disable HT and 2 cores (to not make it overheat with crappy HSF)

    - increase multiplier

     

    You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU.

     

    Usually, it takes about 5 minutes to see if the CPU is good or not.

     

    With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable.

     

    But, that's something you don't need to test. With BCLK adjustments, you'll never get 5200MHz going or so. Multiplier binning is the best way.

     

     

    thanks for this hint.

    im sure many people try to boot the chip, which is difficult due to bad heatspreader and the so caused high temperature raise during boot.

     

    2600K - L051A863 #0108

    max multiplier: 55x

     

    just possible under cold due to massive heat under load:

    51x100 @1,50v - air - boot ok - win 7 - ssd (60 degree celsius boot temp)

    51x100 @1,50v - air - no boot - win xp -hdd (70 degree celsius boot temp)

    51x100 @1,51v - air - boot ok - win xp -hdd (75 degree celsius boot temp)

    52x100 @any voltage - air - no boot

     

    55x100 @1,57v - ln2 - boot ok - win xp -hdd + win7 -ssd

    totally benchstable:

    Cold testing?

    Have you try to enable turbo and set all the multiplyers to 53?

     

    yes, i tried this as well... thanks, but no gain :(

    i have no idea if should be like that, but i can just set the first 3 cores to 53x - the last one i had to keep "auto" otherwise the first 3 multiplier settings reseted back to "auto".

    Cold testing?

    Looks like we are all having issues with 52x+ multi on Jiggabyte boards. I'm also stuck with 52x, rarely 53x with UD3, no matter if the CPU is at -95°C or +35°C :/

     

    Could it be also that there are just some chip that are unwilling to go beyond ~ 5300?

     

    same problem here... no difference of temperature...

    my 2600k boots fine with 52 multiplier, but doesnt boot with 53, not on my ud4 nor the ud7.

     

    but i found out, i am able to boot with 53 multiplier, if i set the baseclock to 99 manually. anyway, no gain in total mhz :(

    If the community asks for it, I'm more than ready to limit the 'normal overclocker' rankings to reasonably prices hardware and leave the pro rankings for all the expensive hardware.

     

    haha, i see a new hot debate starting soon :D

    what is reasonable priced? is it the common 1000 usd/euro for the high end chips?

    how about the intel xeon x5680 or the upcoming x5690 for 1500 euro or even more?

     

    :P

    just played around with the ud4 and 2600k.

     

    cpu is capable of 5,1ghz (51x100) (3dmark06 cpu-test stable) with the following settings:

     

    internal cpu pll overvoltage: enabled

    real time ratio changes in os: disabled

    intel turbo boost tech.: auto

    turbo ratios: auto

    turbo power limit (watts): 1000 (auto works fine for me too)

    core current limits (amps): 500 (auto works fine for me too)

    cpu cores enabled: all

    cpu multi threading: enabled

    cpu enhanced halt (c1e): disabled

    c3/c6 state support: disabled

    cpu thermal monitor: disabled

    cpu eist function: disabled

    bi-directional prochot: auto

     

    voltage settings:

    load line calibration: enabled

    cpu vcore: 1,50v

    qpi/vtt voltage: 1,12v ("normal" works fine for me too)

    system agent voltage: 1,135v ("normal" works fine for me too)

    everything else: auto

     

    achieved with watercooler (single radiator in cold water was necessary as the load temperatures above 70 degree celsius resulted in crashing 3dmark06)

     

    for 5,2ghz i raised the vcore to 1,55volt
