overclocked CPUs with warranty

[chiliwili69]

I only know three places where you can buy an overclocked CPU with warranty. The more OC the more you paid:

 

In US:

in Germany:

https://www.caseking.de/en/pc-components/cpus-processors/pretested-cpus

 

in Spain:

Does anybody know other shops who do the same?

Any experience to share?

you are an advanced techie, belonging to a the lucky few who has PIMAX as well as a pretty nice PC. Why do you feel the need to go down the route of paying a premium for something that you can easily do yourself?

 

In all my of my overclocking life experience I have never managed to destroy a single CPU. Did I take them out of warranty? Sure. Did any of them die? Not a single one.

 

Delidding is a piece of cake, however you can purchase a 45$ tool if you want to do it quickly, otherwise you can even do it with an Xacto-knife/scalpel.  Intel CPU's can take a lot of physical abuse on its periphery as the core chip itself is the size of a thumb nail, i.e. the heat spread cover is x10 larger than the actual chip.

 

And when running OC'ed CPU the only 2 factors to consider are Temperature and Voltage.  Delidded CPU's will run 55-60C max for 24 hours at max possible OC rate, and that's with AIO water cooler system (none of that custom water loop stuff needed).  And voltage? Well, don't be stupid running it at 1.5v.   Keep it at ~1.3 and you're set.

Well.... first I am not an advanced techie... just a basic beginner with OC.  The OC that I do at my home PC is just done by me.

 

The question was more for professional use in the company I work  . We use a dynamic process simulation software which is very expensive and also very single-thread dependent (so all this research for CPUs for IL-2 VR has been also very valid for the other software  ? ).

We buy regularly PCs for the projects we do and our IT guy has no clue about what is overclocking (it is an IT guy with no passion for technology/hardware  ? ), which is exactly what we will benefit in productivity in the company.

So I was looking for letting our IT guy where to buy OC CPUs or even better buy overclocked PCs already mounted with latest components. We found a company in Madrid who do that:

https://www.mantis.es 

The webpage is not updated in 1.5 years (strange) and now they are selling mostly i9-9900K with stable OC (until max 5.2GHz, with stress tests, etc) with ASUS z-390 ROG Maximus XI Apex. And with warranty!.

 

More and more I have became a kind of "advisor" in the company (we are just 60 people) to purchase new PCs and laptops. But it is not my duty. I am not the IT guy. But it is quite simple what we need, high single-thread score CPUs with very low GPU, or mostly Intel integrated GPU, good RAM, etc. For laptop we have jus standardised on MSI laptops. (light and powerful)

Anyone ever tested the i9-9900X for socket 2066?

I believe all the intel chips are still covered even if overclocked as long as its a k model. They can never know if it was or not.

 

Otherwise those sites you listed are correct they sell pre overclocked chips with a guarantee that they will run at those speeds.

What it surprises me is the stress test silicon lottery does. They use AVX offset 2.

 

So when they offer a 9700K at 5.2Ghz, they are not running at 5.2 effectively, but at 5.0GHz!  So this is quite easy for a 9700K.

So, where is the plus here?

 

We need to run IL-2 VR with AVX offset to 0, since IL-2 uses AVX instructions.

Yeah that's a relatively new thing in overclocking, people running with a avx offset are basically doing it for bragging rights.
