If i find the same batch as yours or batch that same the hwbot froum talking is it i can overclock same as yours or them very low voltage

Nah, it's all draw of luck bro.
Same batch doesn't mean they have similar OC capability.
For instance, many said L639 batch was generally great while there are a few other people saying they had a lot of bad L639 chips.

is it ok with this volt to run daily

Each person might have different opinion/acceptance criteria when it comes to "safe" temperatures & voltages.

Some might be worried about chip degradation when overclocking with excessive voltages for a long period of time.

For me, keep the core temperatures lower than TJmax of 100 degrees Celsius and you should be fine. Well, nowadays most motherboards come with over-temperature protection feature so your CPU Is not going to be killed so easily.

Happy Chinese New Year and enjoy overclocking...

delid or not ???

Delid will reduce the core temps by 15-20C.

Nice try but one minute Prime95 won't suffice.
Pretty sure the core temps will shoot up drastically (at least +10C) at/after 20 minutes of priming.
Need a few hours to confirm stability, 3-6 hours etc

Even with 1.248v still suffer with almost 80c full load in one minute

Prime95 is very2 stressful bro.

which one do you choose small fft,large fft ,or custom sir owikh84

Custom blend of course, min/max 1344 FFTs, with full memory capacity

l639
VID 1.168v

Same VID as my L644 chip

Don't do 4K?

As much as I like 1344, there are errors that can happen beyond 1344.

1344 FFT is like an acceleratedsystem stability study, so that you can test stability in a shorter time with Prime95.
Say if you can passed the 1344 with 90%+ available RAM for 15 mins, then your system should be stable for 12 hours of 4k FFT.

Nice chip

Here's mine...


Somehow 5.2GHz @ 1.424v freezes in Cinebench R15 so I think better stop here.
Got an offer for a 7700K binned at 5.2GHz @ 1.3v stable R15, $450 USD
Hmm, I think I will just wait for Ryzen first

[attachmentid=8510699]

i think the score with be same if i overclock to 5.1ghz compare with 7700k , haha

Exactly, bcos of the identical core performance between KBL and Skylake.
But to get that 6700K overclocked to more than 4.8GHz is quite a challenging task LOL.

need some silicon lottery
