I9 9900k

Only the 2 and yeah this is beating my other by quite a margin and the other was pretty good. I shoùld say this one will be 24/7 rock solid stable at 5.2ghz @ around 1.26v. 5.3g should also be doable with a decent cooler.

Are you still using a pump and bucket for cooling?
Good weather for OC this week/weekend :D

Anyone using a Z390 Aorus Master? Also what's the avergav 9900k overclock

Silicon lottery is the only place releasing overclocking figures for a large number of 9900k samples with standardised testing.

They are seeing about 40% hitting 5GHz or higher at 1.3v with a -2 AVX offset. They bin for high stability on cooling like 240 AIOs so their numbers could be considered conservative.

For non AVX workloads and in a system with better cooling (and possibly sacrificing some stability,) the percentage that will hit 5GHz will be higher and possibly require less vcore to get there.

Some updated figures regarding the silicon lottery.

Keep in mind their sample size and that it may not represent your own chances when buying a 9900k.

I think this is useful info for those overclocking. No info yet on why those particular voltages were chosen or any temperature data.

As of 12/07/18, 100% (no change) of tested 9900Ks were able to hit 4.8GHz or greater.
  • CPU Multiplier: 48
  • BCLK: 100.0
  • CPU Vcore: 1.275V
  • AVX Offset: 2

As of 12/07/18, the top 85% (+3%) of tested 9900Ks were able to hit 4.9GHz or greater.
  • CPU Multiplier: 49
  • BCLK: 100.0
  • CPU Vcore: 1.287V
  • AVX Offset: 2

As of 12/07/18, the top 41% (-5%) of tested 9900Ks were able to hit 5.0GHz or greater.
  • CPU Multiplier: 50
  • BCLK: 100.0
  • CPU Vcore: 1.300V
  • AVX Offset: 2

As of 12/07/18, the top 11% (-3%) of tested 9900Ks were able to hit 5.1GHz or greater.
  • CPU Multiplier: 51
  • BCLK: 100.0
  • CPU Vcore: 1.312V
  • AVX Offset: 2

Silicon lottery now have a larger sample size and as such the percentage of silicon meeting their requirements for each bin has changed.

As of 07/12/18 100% of 9900ks can hit 4.8GHz all core, while there has been an increase in the number of cpus able to hit 4.9GHz by 3% taking the number to 85%.

That's the end of the increases.

For 5.0GHz all core the percentage has dropped by 5% down to 41%. Almost 60% of 9900ks wont reach 5.0GHz all core, or roughly 3 out of every 5 9900ks are failing to reach 5.0GHz all core at the settings listed above.

Next a drop of 3% down from last month bringing the percent of 9900ks able to reach 5.1GHz all core to just 11%.
Just over 1 in 10 of the samples they are binning can hit 5.1GHz stable all core at their specified settings.

As always with these numbers there is no telling how representative of the 9900k supply as a whole the stock silicon lottery receives is. However as they bin more CPUs the numbers should more accurately reflect the silicon lottery for those considering buying retail or tray.

Finally, still no 5.2GHz bin listed. This doesn't mean they don't exist, there are probably 5.1GHz samples that will do 5.2GHz, but judging by the fact that no one is offering binned 5.2GHz 9900ks (when there are clearly people willing to pay for it) the number of stable 5.2GHz chips must be tiny.

Well my 9900k hits 100c and throttles from 5 to 4ghz on prime small with the corsair 115i pro. I'm waiting for some new thermal paste and will report back tomorrow with the results. I'm hoping its just bad seating, doubt improvised overclock can be the cause.

Although in normal situations like gaming it sits licely at 60-70c, if i do any sort of video rendering i know there will be throttles a going on

I reported a few pages back about my pc insta crashing on small tft prime95 avx, causing a restart. It seems it may have been because i left cpu current protection on auto. Set it to turbo and it seems to have cured it.

I leave my pc on 24/7 and had experienced a couple of crashes at idle over a few weeks. I presumed it was not enough voltage at idle, I changed my llc from turbo to high and upped my offset a couple of notches. But maybe it could have been my current protection setting? Maybe the pc had been idling and a process starts that loads the cpu and causes the shutdown... Im going to go change to my original settings now and see if maybe it was the vcore current protection setting.
Just a pain because the crash is rare and i could be waiting a couple of weeks to find out.

Here's hoping it is stable.
 
So...is this the best gaming CPU right now and if so, which model would team OCUK suggest?

My use case is gaming and.....erm, watching YouTube car videos and some Excel work. Yea, that's it :D
