Best CPU to Overclock 5400?

[Mr.White]

Hello!

I got the job of CPU overclocking for 5400 MHz and getting 4014 points on 3D Mark, I decided to choose i9-9900K for its factory clock being 5000 MHz with 1070 AMP from zotac and 8GB (2x 4GB) from Corsair 2666 MHz, 120GB HD, 600W Shean, and SilverStone PS 14 (spending all the money)

However, the processor was by no means stable and cool (I put the bios at "x54" and tested at all voltages) when I reached the "2.00" voltage the CPU broke.

Does anyone have any suggestions / help to collaborate with an overclocked starter, or do they know if it is impossible to achieve such frequency at the moment?

Thanks

I've reached 5400mhz with an intel 8086k, with custom-liquid cooling. If I remember right (been a few days ago) I needed a 280 Radiator - a single fan one wouldn't cool it enough to prevent throttling in OCCT. I *think* I had it stable on 1.65v and +4 to the multiplier (might have been 1.60v)

I had also taken a job to liquid-cool and OC a i9-9900k to 5400mhz, but couldn't get it stable, even with the biggest custom liquid cooler radiator and testing voltages up to 1.75v (one of the few I had to accept a 1 star on and abandon).

My guess is the 6-core 8086k has more overclock potential than the 8-core i9, although that's just a theory (also have no idea if there's some RNG on the individual processors in game)

Just so you're aware there -IS- silicon lotto in game. Your figures you give there are unique to the individual chips you tested at the time and may not be typical for all 8086K's or typical for all 9900K's. In PCBS we can buy for example 1000 different 8086K's and half of them may do 80c @ 5400 mhz @ 1.75v, half of them may do 90c, some may do 70c, etc. Also you may get some that might do 5400 mhz @ 1.5v, some might do it at 1.6v, etc. Same goes for the 9900K's.

You might want to watch the videos in this guide, though fairly old now, they have taught me a thing or two about "binning" and OCing etc.

e.g. putting 2.0volts on a cpu is going to blow 99% of them as it's way too much. Hope these help.

Hello everyone, thank you for your help in solving the problem.

I managed to solve it by doing a "Madness", I bought a 8086K and there was a certain amount of money left, so I bought a larger tank, a radiator of 280 and one of 240 (I connected the two), an H700I, and changed to 1070 for a 1060 Mini .

Before performing the above changes, I had the same heating problem, after making the changes, the processor lowered about 20 degrees in stock and remained stable in overlclock (this time I put x53 and slightly increased the base clock)

Follow the images below. (ignore the tubes, I'm starting to improve this technique)

Thanks again

Excellent, thanks for keeping us updated. Glad you solved it :)

I've been experimenting all day after finding this thread a few weeks ago. I hit 5.4GHz on an i9-9900k at 1.75V. I'm using a 140res, 1x360mm rad, 1x120mm rad, and 1x280mm rad. The case I'm using is the Corsair 900D with fans anywhere there was space. For GPUs, I'm using ROG Vega 64s. The CPU only hits mid-50's.

UPDATE: 5.5GHz ON 2.00V

Funny thing I managed 5.4 Ghz on an 8086K but it freaked out on the benchmark. Even though the Time Spy had it running 33.5 FPS on the first test and all tests were high enough to be 20,000's at least... Got me all Got a 6228 total score in TimeSpy with a 1161 CPU, 27,121 GPU score with NO thermal throttling, 98.5C highest CPU temp. 81.16C GPU temp.

I was struggling yesterday to reach 5464 Mhz on i7-8086K. I was about to give up but then I read this thread which encouraged me to hassle a little more. Enough said I spent like next 3 hours testing different cases and cooling systems, but finally made it with Corsair 900D case and like 3x360 radiators on 1.9V

It's not so much the case or the cooling system that is effecting overclocking in this game. You can get to a point in cooling where you are able to keep a 8086K @ 4.3 Ghz @ 60c under load and it still may not overclock to 4.3 Ghz even with better cooling.

It's like I said above: Silicon lotto. You could buy 1000 x 8086K's from the store and you may happen to get lucky to get one that will do 4.3 Ghz stable. It is completely random in-game. Also random attributes include: Thermals, and voltage.

Different chips from the store may have one 8086K that could do 4.3 Ghz with only 1.60v, or yours that requires 1.90v. You may get one that does 4.3 Ghz with 1.60v yet run 80c in a big custom water loop or you may get another one that does 4.3 Ghz with 1.60v that does 60c in the same loop. It's completely random.

Kinda strange, the 900D won't let me install but 2 360mm coolers in the front. The top stays reserved for 2 140mm or 1 280mm only, with 1 120 or a 1 240 in the rear. Did you try to bench your 5.4Ghz on Timespy? Like I said it flawed my run with a 6228 total score, but a 27121 GPU score for 2 2080Ti's, liquid cooled as well of course... No way it can run 27000+ GPU score and the CPU is sitting still at 1161...

Sorry I dont rememeber how many and which radiators i did fit, but I remember I threw in everything possible and it was alot :)

I wanted to remind y'all that in PCBS multiple small radiators will give you better cooling performance than multiple large ones. I know it is in opposite of real life but that's how it works in-game. For example: 6 x 120mm radiators would cool better than 2x 360mm in PCBS.

Nah tried that, they must have fixed it with the last update. Way better cooling with the raijintek 360 radiators.

did u run any tests or just started at 5.5?

If you're trying to get 5.5 ghz on a 9900K in-game then you can't just repeat whatever they did and expect to get it. It's completely random how chips overclock in this game and they just happened to get lucky to get a chip that OC's well. Most likely you'll never see their overclock with a 9900K yourself.
