I9 9900k

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.

Bins are created for stability in nearly every workload and tested using a 240AIO. These percentages can be considered accurate, conservative or optimistic depending on your own expected use and cooling.

As of 2/6/19, 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 2/6/19, the top 86% (+1%) 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 2/6/19, the top 39% (-2%) 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 2/6/19, the top 8% (-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

As their sample size increases both 5.0GHz and 5.1GHz samples again show a drop making them even rarer while 4.9GHz has become slightly more common.

A bin for 5.2GHz or higher is still noteably absent for the 9900k unlike the 9700k which had the 5.2GHz(10%) bin added at the end of last year/beginning of 2019.
This shows that silicon lottery is willing to update their bins when a new frequency becomes available in sufficient quantities, and that even with an AVX offset, 5.2GHz+ samples are in such short supply that there aren't enough that meet their criteria to be considered for sale as yet.
This mirrors the listings from both Caseking and OCUK that sell frequencies up to 5.1GHz with AVX offset but nothing higher.

I'm in the top 39%. I win 1 extra FPS! I'm just happy it's an even number at 5GHz. That annoyed me more than anything.
 
I rather run at 5ghz with 0 AVX offset because BF V uses AVX and that's one of the biggest real world loads.

As for stress testing, I've minimized it based on experience. Here's my quick and dirty for stress testing and benchmarking that hasn't failed me yet:

CPU
- 2 cinebench runs
- 1 Intel burn test run through (Default)
- 2 intel xtu runs
- 1 hr of battlefield 5 64man multiplayer < this will crash for sure with any issues. DX12

RAM
- 2 IBT
- 2 cinebench
- 2 Intel XTU
- 1hr of Dota 2. Dota 2 seems more sensitive to RAM than BF V and other games

GPU
- 3 timespy runs
- 1 hr of BF V MP

Each his own but I'm not going to have a machine sit there running Prime95 or memtest for hours on end. I put them in order of running them. The goal is to fail right away. Each test you go down should lead to lower chance of failover and is more of a validation of the results with the gaming session being the most "dynamic" element.
 
At the end of the day it is down to the individual as to what they consider "stable", i'm a great believer in if it does what you want it to do for everyday use, and doesn't GSOD, all is well. JMO.:D

This is the only reason (right now) why I want bf5 :D

I know what you mean. Being so close to 5GHz but not able to reach it, especially when others can, would be incredibly frustrating. What difference does 5 make over 4.9 or even 5.1? I don't know, but the psychological impact is real.

10/10 can confirm. was considering selling and buying a new one for that 0.1ghz but then the Mrs doensn't knw about the 2k pc debt :P

Yes, I run with 5GHZ 0 offset for this reason, too. Although DX12 on NVIDIA cards can still be jarring in this title. I stick to DX11.

I don't have the game but I run my OC with 0 AVX offset all the same. I do keep reading that BF5 doesn't like overclocks at all, but it sounds like either those complaining aren't actually stable, or they aren't AVX stable.
Since I don't own the game I can't weigh in one way or another, but I'm watching the sales so that I can add another 'stress test' to my arsenal. :D

Oh really? I guess I hadn't really looked online, but yes it's a fairly brutal test of stability as far as gaming is concerned. Those complaining likely aren't stable. If not wanting to sacrifice the magical 5GHz, it can sometimes help to reduce uncore ratio. Depends how conditional the overclock is.
 
This is where I am at with my 9900k sample, this will do for me I think. 1.325v in bios, under load its 1.288-1.296v with a LLC of 6. Max temp on one core of 87c.

^^always found LLC 3-4 best for asus but was z270 days, less rise then entered voltage and didn't spike hugely

how does the vrm hold up after testing ? then again dont think your doing AVX workloads and just gaming ?

I have always used an LLC of 6-7, 3-4 gives far too much droop, my IX Apex (Z270) I use LLC 7, XI Hero LLC 7, and my XI Extreme LLC 6, and always use a manual vcore.

VRM on the XI Extreme is very good, mid 40's under full load, no I don't use AVX or game, I am just an enthusiast.

5.2 is damn nice ! ram clocking fun next ?

He's running straight 13s at 3200. Whether that's conditional or not is for moorhen to answer but it's very tight for a daily rig.

Yes Straight 13's SS, 1000% HCI tested, as you know from another forum, this 3200mhz CL14 kit will do 4234mhz at 19-19-19-42, 1.460v. ;)

But not on this Extreme board, ram overclocking is not its strong point, waiting for the XI Apex.

The Extreme is great with memory, however it's still a 4 DIMM T-Topology board, which doesn't favour 2 DIMM configurations as well.
