the bigger chip looks promising if you have cb below -120 and a good contact with the pot.

 

The i7 is not delidded, but I have never tryed LN2 on a pricy piece of hardware like this... I need some help to reach high frequency cuz I have never used LN2 before and do not want to ruin the chip... I only want a high freq validation than I will sell it.

air validation is not telling much.. try superpi 32m @ 5 GHz at the lowest possible voltage in win xp.

 

Aint air this validation, it is "cold" liquid (I do NOT have a waterchiller, it is redneck method), spi I have done it under win7 cuz I was only proving the low voltage, the score was not the priority!

By cold, we usually mean liquid nitrogen.

 

The validation you did is just a CPUZ validation, which can often go significantly higher than the actual "benchable" frequency.

 

At what voltage did it pass SPi32M? :)

maybe,MAYBE I've found something good.

 

X437B366 4790K

 

1.025v VID

1.05v 4500mhz wprime32m , hwprime

 

1.070v 4500mhz cb11.5

 

1.285v 5000 4c/8t boot

1.275v 5000 4c/8t 32m

 

1.245v 5000 2c/2t 32m

 

on ambient 26°C- normal aircooling. (Y)

Nice one!!! What sort of stable runs are you getting??

 

http://hwbot.org/submission/2761856_subaruwrc_cinebench_r11.5_core_i7_4790k_11.81_points

 

5.9 cb 11.5 with only 1.46v

didn't push higher cause get excited and went for pi32m

 

pi32m run at 6.3gig with 1.61v at -132°C relatively easy.

Now Im taking care of her and waiting for a potent VGA then push the 2D again.

 

Sort of scaling with volts. 6600 with 1.77v - 6700 with 1.82v more does not really help. End of heat dissipation capability. IHS seems good,Gelid GC-extreme used.

 

Cpu is in stock shape,neither delided nor polished.

Im really statisfied with it so far

What are some standard guidelines for binning 4790K, not including cold results? <1.3v for 4c/8t 5ghz 32M or is would that be an exceptional chip?

 

For the very best chips that's what you look for yeah. I just sold what was a pretty decent chip that managed to do 5GHz boot at 1.35v and would do 5.6GHz Super Pi @ 1.55v on single stage.

 

I found some chips that are great on air that have absolutely no cold scaling and some that are terrible on air but scale really well on cold too. I hate Haswell for that xD
