Skylake 6700K/6600K Batch and Serial Numbers

[Lucky_n00b]

I like it! Will you be testing the better samples for higher frequencies (5GHz)?

 

Yeah sure!

But maybe have to wait a while since these cpus will be used for an Indonesian amateur oc tournament next week

ambiant T°25/28°, cooled with a NH-d14+mx4 : nb x40, unstable xtu full run @4.8 for 1.4vc, cinebenchs @4.8 for 1.37vc stable

 

testing in this week with my cascade

Hi guys, i'm testing a 6700k cpu Batch#L520B669

 

1,31VID - 4.6ghz@1,30v (cinebench).

 

But i've a problem, in idle state the cpu always scale down to 40x. I've disabled speedstep and c-state, only turbo mode enable, but always scale down.

I miss somethings?

[Guest barbonenet]

Very high vid frank....try if you can boot at 5ghz...and your max xtu stable on air/wc....if you are under 4.8 u can sell it

[rtsurfer]

Tested 2 pcs 6700K, L523B383

 

#1 VID 1.312V. 4.7G CineBench 1.40V

#2 VID 1.292V. 4.7G CineBench 1.38V. (4.8G CineBench 1.45V).

 

XTU on both chips requires an additional 0.01mv. No delid.

All updated!

4c/8t 4,7ghz@1,40v XTU

4c/4t 4,9ghz@1,50c SPI32M

Updated

[ObscureParadox]

anyone else get really weird scaling with their CPU?

 

My 6700K can easily do 5.5GHz with less than 1.6v XTU stable, but 5.6GHz 4c/8t isn't stable on even Cinebench at any volts, just the strangest thing and not sure where my issue lies........

 

If it's the CPU then will just get the 5.5GHz XTU run done and sell on.

[xxbassplayerxx]

Sounds like a voltage issue... Where are PLL volts?

[ObscureParadox]

In the right place No combination of PLL volts makes a difference, at full pot vs -120c at 5.5GHz it acts the same, second it gets to 5.6GHz it's a no go... don't want to give up on the CPU but running out of LN2 here

[xxbassplayerxx]

Delidded?

[ObscureParadox]

Nope, but doubt I will gain anything by doing so since in XTU I don't look to be hitting positive temps in XTU so I doubt the package is getting that hot, not that 100MHz should make that much of a difference anyway...

[Alex@ro]

Do it anyway,you might get suprized

[ObscureParadox]

Do it anyway,you might get suprized

 

My fear is that if the CPU really is this bad and that my oc issues aren't temp related then delidding is just going to be a risk of killing a CPU with no gain and that in turn makes it harder for me to sell later

[Massman]

Sounds like a delid problem

#2 cannot boot 4.9G 1.50v reject

 

6700K L525B538 VID 1.37v

boot 5G at 1.45v, 0.02v higher 32M stable

LN2 -145C 1.50v 5.2G XTU

after delid

LN2 -145C 1.82v 6.0G XTU

my best chip so far, uncore goes also skyhigh

No delid no glory man... it is the only way....
