ASRock X299 OC Formula Review
Why you can trust Tom's Hardware
How We Test
Additional cores create additional thermal and power loads that can push other hardware to its limits, yet the parts we’re hoping to push to the limit are all on the motherboards. Intel’s 10-core, 20-thread Core i9-7900X CPU is a great product for stressing the voltage regulators of various X299 motherboards, particularly under our full-AVX-load overclocking stability test.

Network | Integrated Gigabit Networking |
Graphics Driver | GeForce 382.53 |
The tremendous heat produced by the Core i9-7900X required us to use nothing less than our award-winning Fractal Design S24 liquid cooler system sample. Getting its fans to blow sufficiently over each motherboard’s voltage regulator required additional design consideration: Of our leftover case review samples, Cooler Master’s HAF-XB had the best layout.

slicedtoad Hmm. I think this board (and all of the x299 boards that achieve 4.4ghz) needs a better cooling solution to really test it. Either LN2 (which would likely be a nightmare to use as an objective test) or maybe delidded with a custom water loop. Delidding is fairly effective on x299 (replacing the TIM with something decent).*Reply
Then again, this article serves as a good example of the woes of overclocking a 10 core cpu. The motherboard isn't going to change the results much for most users because heat is usually the first problem.
*Why Intel decided to skimp on TIM with their $1000 CPUs, I have no idea. But I really don't think penny pinching is a suitable explanation. -
ElMojoMikeo It would appear that we have indeed hit a massive impasse on cooling. I am currently running older 39x0X processors on X79. I have spent a lot of time in the past tweaking them to stay inside their thermal limits. I am now looking to start upgrading them. The first thing I have been looking at is cooling. From bitter experience. I know that these new SkyLake X processors will be hard to live with on a daily basis without adequate cooling.Reply
Delidding six $1000+ processors. For those that don't know it requires special tools and nerves of steel. Once you have popped the IHS off, all warranties are void. So it's not really an option.
Open Challenge:
So the question now is. Is there a cooling system available anywhere at any cost that can keep a Skylake X processor from throttling under Prime95 on all cores? Without voiding any warranty.
I can't do that with the processors that I have now. So what hope has a Skylake X with more cores, cache and power consumption. -

Nope, recycled chart with missing title update. I thought I'd caught all of those :)20261602 said:7700k compatible ?

ohenryy I keep wondering why we dont see the oc formula on the am4, I guess they really just want crazy overclocks and know AMD cannot really go as high as intel?Reply
