Overclocker gets AMD Threadripper 3990X Running 5.3 GHZ on all 64-core (LN2)

Wowzers, get ready for the world's faster Cinebench run, overclockers by the name of Tsalk and Splave put some LN2 on the 3990X and started overclocking. The result 5.3 GHz on all cores, and also 5.5 GHz on a single core.

The processor we reviewed last Friday appear to clock quite well when sub-zero cooled. The 5.55 GHz from Tsaik is for a single core, he used a single ddr4 module that ran on ddr4-1866 with CL13 timings. The motherboard used was an MSI TRX40 Creator. Splave on his end achieved 5.3 GHz on all cores with a TRX40 Taichi from ASRock,32 GB G.Skill's Trident Z Neo ddr4-3200 memory at CL11 timings. As you have seen in our review, power consumption at high clocks is pretty crazy, they used two power supplies of 1250 watts

All this resulted in a score of 39,518 in the multithreaded test of Cinebench R20. In our own test, the 3990X achieved 24,608 points.

Holy crapola, what was the total power usage for that?

GN used supernova 1600w to reach 5ghz but idk how power usage was.

You realise that a lot of the big manufacturers have ln2 overclockers in house? Intel has a dedicated OC team that runs Ln2 on lots of chips. So it has significance.

It's also for fun not sure why some people need to assume it for big ego's to get off on (not aiming that at you fantaskaresef, just can't be bothered to quote everyone lol) it's the same reason people Drag race etc

Oh yes I am aware that they have it. For bragging rights between companies ofc, publicity and you never know who buys a Kingpin card over a normal one e.g.
Doesn't change much about what I wrote though but you are right

I don't really understand why people feel the need to point out the significance of LN2 overclocks. Yes, it is meaningless, but aren't most of the things we discuss on these forums petty? Is it really worth spending 30% more for a 5% performance increase? Do you really see a noticeable day to day difference when RAID'ing M.2 drives? Is it really that bad if your PC isn't nearly silent?

We're enthusiasts, aren't we? Overclocking a 64-core CPU like that is, at the very least, interesting, because it's pushing limits we've never seen before. How often have you seen a single CPU consume over 1KW of power?

Exactly, this clearly is not about practicality but abput pushing the limits to see whats possible.

64 cores at 5.3 is INSANE.

And yes, I cant even understamd how that CPU can take 1kw of power. My kitchen cooking pot has 1kw but is much bigger and very stupid compared to CPU, its just a piece of iron. That CPU is very delicate and fragile, how it can take 1kw is baffling.

Wow, what a beast.

And it will drive the progress a lot.

I like to see stuff like this because it's shows what hardware can do at insane levels.
