this is a overclocking forum - many here will find it worth it

To be fair any OC'er would have found a Gold sample (a KS) if they really cared in the first place surely? I see this product as only being desirable for the ultra-niche "must have top range'rs", people who were looking at a K for a long term upgrade or a stop gap before Intel actually releases something interesting.

The problem with the long term upgrade or stopgap... is that clearly Intel doesn't fancy it's prospects beyond a year of use, so it's a very limited product to me, i certainly wouldn't buy if Intel suspects it'll die after a year, you won't be able to resell it to upgrade realistically without a huge loss. The weirdest thing though is that it doesn't really... do anything for Intel, they already have a large margin in gaming, a little bit extra that you could have achieved with a gold sample anyway is, i feel clutching to keep in the news i guess?

I'm not the market for this, clearly, AIBU?

Not for me neither

I won't look at the KS, not with the 10 core 5.1ghz comet lake coming soon and ryzen 4000 thereafter

Anyone with this chip, how are your stock temps before any OC?

I seem to sit around 27-29 degrees idle and under a cinebench r20 bench run hit between 71-75 degrees. This is on a 280 aio.
This is at a ish room temp of 21 degrees.
From Hwinfo core seems to be at 1.25/6 (currently all in auto) (only non stock settings are current limit which is set to 140% and power duration limits which is set to max)
*edit - and MCE disabled.

That second part.. you can certainly edit and flash GPU bios files, at least for AMD gpus you can. This is how you make a little rx550 a mini hashing monster. Nearly 18mh/s on eth for a cheap gpu if you dont mind spending ages messing around modding and flashing cards. Vega can also be flashed as can Navi.

Locked on NAVI... Cant edit bioses on AMD or NV now

looking at the reviews, it will switch down to a 4.7ghz clock for cinebench. That said, the fact you are running the cpu on a 280 is good news.

1.25v seems to confirm what the other reviews were posting.

I'm sure it didn't down clock on the cinebench run, HW info tracks min and max clock, it deviated to 4999mhz -5002mhz. so as far as I'm aware it remained at the 5Ghz mark.
I was expecting the 280 to struggle given how hot everyone said how hot the 9900k run, but these temps seem quite acceptable.

The temps will vary based on workload and stress level. P95 non avx small fft's are a good way to test the limit of your cooling. Then you'll know exactly how many amps and watts you can handle.

Those 5.2GHz-5.3GHz 9900ks's are selling for $1100-1200. https://www.digitaltrends.com/computing/intel-core-i9-9900ks-5-3-ghz-1100/

If you are going to build a system with a 5.3GHz 9900ks in it. Then you should get it delided and go with direct die cooling. 8-pack rips them off with his bear hands, without breaking the die. https://www.reddit.com/r/pcmasterrace/comments/aqwxxn/i9_9900k_direct_die/ https://youtu.be/-LecJjk-LrI

Then get the expensive high frequency RAM dialed in with nice tighten timings, see Corsair’s Vengeance LPX DDR4 5,000MHz kit? Or don't buy the RAM yourself and let 8-pack work his magic. Or get a Vengeance LPX DDR4 5,000MHz kit and let 8-pack work his magic.

Then find out you are gpu bound with one 2080ti, so now you have to get another one. So what about the temps? So you start thinking about that big rad. https://www.reddit.com/r/watercooling/comments/8f6hed/external_rad_and_pumping_station/ and decent pump.

Just not enough? Chiller time maybe, tell mum the fish died https://youtu.be/HMtvEbD2MQo
go with plan b https://youtu.be/VDEu7zPTNu4
or plan c move to Yakutsk and its fine overclocking weather. All-time record low recorded is minus 83 F (minus 64 C) in 1891, its like free phase change. https://www.nationalgeographic.com/magazine/2018/02/explore-yakutsk-russia-coldest-city/

Or go for a silent build, https://youtu.be/5QXp-UwrmEo https://youtu.be/4d0B0Dli-1g https://youtu.be/cPvlW9-Ijjc You are tired of 5.3GHz anyway and want LN2 type frequencies 24/7. After all you can start your own youtube channel.

Joking aside, get 8-pack to build it for you if you really need every single point in time spy.

Did linus attach a fridge to that PC? the "phase change" motor looks like a Fridge motor

That's an off the shelf solution from ldcooling. Does not state what the compressor is but does state that it adds 4mins to boot times. You of course get the free silent cooling of phase change.
http://www.ldcooling.com/shop/24-l

From the video 2NF11FX.2, http://files.danfoss.com/TechnicalInfo/Dila/06/nf11fx2_r134a_115v_60hz_06-2008_ed402v222.pdf
https://youtu.be/4d0B0Dli-1g?t=814

  • Application Vending Machine, Light Commercial Refrigeration
  • Nominal HP 1/3
  • Energy efficient compressor is heavy-duty, operates with low noise, and is rugged enough to operate under tough operating conditions.
https://www.grainger.com/product/SECOP-Refrigeration-Compressor-48TP46

About $200 each approx.

A good sample will do 5.2 on a 360aio. The difference between that and 5.3 is investing a lot more into a cooling system.

my cooling recommendations would be:
360 aio
Direct die
Custom loop

in that order.

That setup will have issues, you can hit near 300 watts for that overclock. https://www.kitguru.net/wp-content/uploads/2019/10/Power-1.jpg At least you get that cooling is a big issue. Only 3% can do 5.2GHz @ 1.325 volts and avx offset of 2.

Example, 5.25GHz all-core speed at 1.375V https://hexus.net/tech/reviews/cpu/136145-intel-core-i9-9900ks/?page=10

Quote "It's worth knowing that Blender system-wide power consumption jumps from an already-high 236W to 271W." End quote.

It's funny how they just added another fan to their Noctua cooler but speak about 271W in blender. Note a 4.7 GHz all-core and a constant load are quite sufficient to make air cooling absurd.

Just image whats going to happen with prime95 small fft runs. Most likely it will run considerably cooler at 5.1 GHz thanks to a massive reduction in voltage. I don't think a custom water loop with 360 rad is going to like 300+ watts. https://cdn.mos.cms.futurecdn.net/tdauREAwqYvHhsTjDHesSH-650-80.png This is a avx offset of -2 and 1.33V Vcore. Here is AIO vs chiller https://cdn.mos.cms.futurecdn.net/L4VXhJWFyumXDsrkR6QFNL-650-80.png I like the 64c temps of the chiller and not the 90c temps of the AIO. Power consumption is better with a chiller too https://cdn.mos.cms.futurecdn.net/LYS7BzgNoazb6UAUfCa43a-650-80.png

The best way to get 5.2GHz is to get a chiller. A 240mm Corsair H100X AIO can't even keep a stock 9900ks cooled. https://www.kitguru.net/components/cpu/luke-hill/intel-core-i9-9900ks-5ghz-8c16t-cpu-review/10/

mine runs 24/7 and average draw is about 90-100w in gaming. 5.3 1.395v.

i think running 5.3 on a 240/360 AIO is fine as long as you run a good AVX offset (-5) and limit the TDP to 120w so that if anything tries to spike the power you won’t spin the fans up hard. That way you get a nice speedy rig without the worry.

Mine was on a AIO before i upgraded to a car radiator and it was fine but the fans span up too hard for my bat ears.
