leeghoofd commented on 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)

it was a 5ghz 4c8t 1.385v?

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?

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

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.

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

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

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

What did you expect dino :P

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

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

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