Dissuade me from buying 9900K

This is for CPU only obviously. That's after spending 6-8 months on the same setup trying all sorts of different stress tests. I'm happy to recommend that to anyone looking for stable CPU and be confident that their daily mainstream systems will be fine for gaming, compiling, rendering and desktop usage.

Other components (ram and GPU) need their own stress tests.

You can do as you please with your setup. Each his own.

It can take 6 hours for errors to start happening. Stable is 10 hours prime fft8 and 10 hours max fft. 2 hours any program is far too short. RAM also is stable for me for 2hours of mem test but always fails after 3-4 passes, right at the end. This is why stress testing takes so long.

The above test is 225watts 98c maximum temp and 1.4vcore with turbo LLC. RIP chip 24/7. Don't run prime95 8fft on that overclock, it's hotter. Also prime95 requires the most vcore for small fft8k runs.

There is also a 8c difference between cores. 98c is only 2c from max.

Thank you for testing that! Your cooling is pretty bad ass for sure. It's been a while since I ran real bench but I generally needed a lot lower vcore to pass real bench than i do occt/x.264/x.265. I'll run my daily 5.1 setup tonight and share.

Why is your system agent clock 800mhz? I thought 1000mhz was standard?

This is OCCT after 2 hours. 1.4v bios turbo llc, 52/47x. Alphacool 360LT with Kryo on the IHS. I'd just be happy dropping 10-15c off this honestly.

Yeah I mean, the MO-RA 420 Pro is similar to 2x580 radiators so that shows you where you would need to go to get your temps down by 20C, to get them down 10C then you are looking at adding in a single 580.

Thats why I went for a floor standers this time around with quick disconnects.

Buying a 9900KS might be cheaper and less hassle to drop your temps by 10C @ 5.1.

Don't know about the 800mhz clock, it is the ASROCK default, it might be why I am slower in Cinebench.

He could lap the CPU heat spreader, get that 98c core down to 90c or if there is a mounting issue. Fix it. Pay overclockers/8-pack to de-lid the CPU. Buy a chiller like https://www.overclockers.co.uk/hail...-hc500790watt-cooling-capacity-wc-004-hl.html for example. https://www.aquatuning.co.uk/water-...tra-titan-1500-hc500-790watt-cooling-capacity £544.53

this is the overclockers forum, people spend £1250 on a phone which lasts them 12 months :)

these rad setups can run for years and there is no problem with me switching it over to AMD all i gotta do is replace the chip+board, i will be done in about an hour, if/when i do switch it, it will run as whisper quiet as it is now, that is what you pay the extra money for - peace and quiet.

The setup costs around £700 once you factor in the fans, quick-disconnects, blocks, pump, res and other bits. I will do a build log once the aqua d5 next is in.

I can say now that it is all beautifully designed, made and finished, probably some of the best money i have spent, I would be running this setup if it were a 9900k or a 3900X because the 5700XT AE was a pain to cool when overclocked and a triple rad, just for the 5700XT was not enough :)

If you are going to really overclock that CPU and don't care about money. Buy a chiller, you don't need any rads but they can be loud. Phase change is a bridge too far. https://bit-tech.net/reviews/tech/cooling/hailea-hc-500a-water-chiller-review/1/ The issues will be there with sub ambient cooling but taking your coolant temps to 0c or even below will get you a much better overclock. Try here for one under £500 https://www.aquatuning.co.uk/search?sSearch=Hailea+HC-500A&p=1 Also here is a review. https://bit-tech.net/reviews/tech/cooling/hailea-hc-500a-water-chiller-review/1/

The issue is that you will spend a lot of money on rads and not get much more overclocking. With this you should get more but your vcore is also already at 1.4volts. More rads can't get you below ambient temps for the coolant. This will keep your graphic card at approx. 30c or less under load. https://bit-tech.net/reviews/tech/cooling/hailea-hc-500a-water-chiller-review/4/

This chiller is the cheapest but is only 265 watts https://www.aquatuning.co.uk/water-...65watt-cooling-capacity-white-special-edition £353.94

I would be happy with a 5GHz overclock all cores with no avx offset, get really fast ram and call it a day.

£700 is chiller build level spending. Get a 800 watt chiller for £500 and bypass the thermostat so it can take you to -20c. Then you can overclock with high vcore. Just insulate everything very well.

With a chilled water I remember a video were he reached 5.3GHz. https://www.youtube.com/watch?v=hc_T57d56AY

Chilled water 4.6GHz all core destroyer of worlds 3900x https://youtu.be/cotgANmjAcY

Looking forward to your build log. I'm going to do mine in increments so it's more of an experiment in how different steps impact temps. I went from air to alphacool and noted those results. Next step is direct die on the alphacool. After that will come a custom loop. That's where it's going to be a toss up between a multi rad setup or an external unit like the MORA

I would have done it but an ugly loud Chiller won’t get past the female police on a number of counts and the one i wanted only goes down to 20C and my loop is already at 22C.

Polished shiny shiny aluminium and led lighting on the other hand....

Seems it pretty goods as is, just need to get vcore down if you can.
 
Hopefully when the 9900ks is released and there is plenty of availability it will bring down prices on the 9900k -9700k
 
Think it will be a very limited availability part as there won’t be that many 9900K that will qualify.

It’s just that intel had to offer something as response against Zen 2, 10 core on Z490 H1 2020 so very much like 8086K.
 
I wasn't asking for proof, although 15 minutes is very weak. Would consider 1 to 2 hours at least if looking to post any kind of tangable proof. Nice temps, I have the Phobya 1080 here but it's reserved for HEDT.

That's fine, here is a realbench 15 minute stress. fans at 200rpm.

Yes Yes Yes I know the prices are coming down, but I pulled the trigger and installed a I9 9900K and a ROG Maximus WIFI (definately update the BIOS before you do anything, nice and easy as the board comes with everything you need to pull it from the web without having windows running) did a generic OC supplied with the board nothing fancy, stable at 5.0 and ram running at 4.3k (from 4k)... no messing took an hour from start to finish as shes purring like a kitten.

All ready for some low end 1080p gaming maybe 720p who knows.. (only put that in because I know it for some reason annoys certain people)

I know I really should have gone the AMD route but I'm lazy and this was the cheapest and quickest option for "me"

To be honest and to answer the OP's main point about ARMA, I can run ARMA on 1440p with pretty much all bells and whistles now then again though I could actually do that on my 8600k..

9900KS is just the same old 14nm inefficient CPU that the 9900K is. It's basically factory overclocked by Intel.

It still spits out too much heat and draws way too much power for an 8-core. Compare it to the 3800X in those metrics.
