leeghoofd`s Core i7 4770K at 5655.6MHz with an ASRock Z87 OC Formula motherboard

This profile was made on a system which does not allow overclocking. Try to enabled overclocking related options in your BIOS, or use a different motherboard. Applying downloaded profiles may not work.

Sorry, we do not have enough data collected for a {0} yet. If you make a second analysis, we''ll be able to draw the chart properly!

    Belgiumleeghoofd commented on his own score:

    Retesting 5ghz 1.385 Vcore CPU, no go over 6ghz 1core, 4/8 seems acceptable, CB at -115°C Not tweaked for performance (as usual)

    Farjam says:

    it was a 5ghz 4c8t 1.385v?

    Belgiumleeghoofd says:

    yep, boots at 1.385 into win7 4/8 and runs 1M, AIDA CPU Queen, PhotoworXX on air.

     

    Same CPU runs 4600 1.23Vcore AIDA stress test stable.

     

    Re-testing the other one tonite... wished it could do 6100 1 core and 5800 all cores, but nope...

     

    None optimised runs with the Corsair 2800C11 CFR kit... +1400 should be doable at them CPU speeds...

    Which batch is this one?

    Farjam says:

    so voltage on air is not always an important sign , my 6280mhz 01 chip was 4c8t 1.385 only for xp... but not bad with ln2... and i had an 6200 chip for 3Ds and 6050 for 06 that could not boot even 4.8 below 1.4v on air. and some 5ghz 1.41v that can not pass 06 @ 5700

    Germanyder8auer says:

    I think you still need low voltage on air but it has to scale on cold and high voltage.

    My first 4670K did 1,15V 4500 MHz primestable which was a very good one. 6,3 GHz max valid and 6,1 for 32m.

     

    I had a 4770K which did 4500 MHz at 1,175 Volt which is just a little bit worse but it did not scale on cold at all. 5,9 GHz max on LN2...

     

    But the L313B996 ones which only did 4300 MHz at 1,275 V primestable were 5,5 to 5,6 max valid on LN2.

    Belgiumleeghoofd says:

    Batch is L316B432 sr nr: 35310047A1952

     

    This chip needs high uncore/NB, eg setting it at 50X would shutdown the setup at +5800Mhz, with 52X it was far more stable...

     

    looking for better :P

    you looking for some chips like this? ...

    1.088 for cinebench :D

    Belgiumleeghoofd says:

    just want a bulletrpoof retail +6Ghz bencher for 3D 4/4... my quest continues...

    1.088 for cinebench :D

     

    And then you end up with a CB at -90°C and a max clock of 5,8 haha

    Farjam says:

    nope only only only on this one i was not so bad luck :D cb is -116 and 3Ds 6350-6400 and 6540 pifast, i buy cpus from one same batch to make sure about not a very bad cb :D

    AustraliaDinos22 says:

    scatter benching as usual :D

    Belgiumleeghoofd says:

    What did you expect dino :P

    South AfricaVivi says:

    interesting cache behaviour there albrecht, i have found my chip shut down earlier than normal sessions, so ill try mess with cache a little :)

    Germanynfszocker says:

    5.65GHz/1200MHz and 1370m of score, is no good efficiency;)

    Belgiumleeghoofd says:

    No tweaks applied to the rams as mentioned in the comment :P this is done on a daily OS too... just testing a CPU...
